<dc:title><![CDATA[MsRi-CCF: Multi-Scale and Rotation-Insensitive Convolutional Channel Features for Geospatial Object Detection]]></dc:title>
<dc:source><![CDATA[Remote Sensing 10(2018)12, 1990]]></dc:source>
<dc:date>2018</dc:date>
<dc:description><![CDATA[Geospatial object detection is a fundamental but challenging problem in the remote sensing community. Although deep learning has shown its power in extracting discriminative features, there is still room for improvement in its detection performance, particularly for objects with large ranges of variations in scale and direction. To this end, a novel approach, entitled multi-scale and rotation-insensitive convolutional channel features (MsRi-CCF), is proposed for geospatial object detection by integrating robust low-level feature generation, classifier generation with outlier removal, and detection with a power law. The low-level feature generation step consists of rotation-insensitive and multi-scale convolutional channel features, which were obtained by learning a regularized convolutional neural network (CNN) and integrating multi-scaled convolutional feature maps, followed by the fine-tuning of high-level connections in the CNN, respectively. Then, these generated features were fed into AdaBoost (chosen due to its lower computation and storage costs) with outlier removal to construct an object detection framework that facilitates robust classifier training. In the test phase, we adopted a log-space sampling approach instead of fine-scale sampling by using the fast feature pyramid strategy based on a computable power law. Extensive experimental results demonstrate that compared with several state-of-the-art baselines, the proposed MsRi-CCF approach yields better detection results, with 90.19% precision with the satellite dataset and 81.44% average precision with the NWPU VHR-10 datasets. Importantly, MsRi-CCF incurs no additional computational cost, which is only 0.92 s and 0.7 s per test image on the two datasets. Furthermore, we determined that most previous methods fail to gain an acceptable detection performance, particularly when they face several obstacles, such as deformations in objects (e.g., rotation, illumination, and scaling). Yet, these factors are effectively addressed by MsRi-CCF, yielding a robust geospatial object detection method.]]></dc:description>

<dc:source><![CDATA[Physical Review B 81(2010), 214415]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The transverse acoustic wave propagating along the [100] axis of the cubic Tb<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> (acoustic c<sub>44</sub> mode) is doubly degenerate. A magnetic field applied in the direction of propagation lifts this degeneracy and leads to the rotation of the polarization vector - the magnetoacoustic Faraday rotation. Here, we report on the observation and analysis of the magnetoacoustic Faraday effect in Tb<sub>3</sub>Ga<sub>5</sub>O<sub>12</sub> in static and pulsed magnetic fields. We present also a theoretical model based on magnetoelastic coupling of 4f electrons to both, acoustic and optical phonons and an effective coupling between them. This model explains the observed linear frequency dependence of the Faraday rotation angle.]]></dc:description>

<dc:source><![CDATA[Dalton Transactions 39(2010)45, 10953-10958]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Using density functional theory (DFT) calculations, we revisited a classical problem of uranyl(VI) oxalate photochemical decomposition. Photoreactivities of uranyl(VI) oxalate complexes are found to correlate largely with ligand-structural arrangements. Importantly, the intramolecular photochemical reaction is inhibited when oxalate is bound to uranium exclusively in chelate binding mode. Previously proposed mechanisms involving a UO<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)<sub>2</sub><sup>2-</sup> (1:2) complex as the main photoreactive species are thus unlikely to apply, because the two oxalic acids are bound to uranium in a chelating binding mode. Our DFT results suggest that the relevant photoreactive species are UO<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)<sub>3</sub><sup>4-</sup> (1:3) and (UO<sub>2</sub>)<sub>2</sub>(C<sub>2</sub>O<sub>4</sub>)<sub>5</sub><sup>6-</sup> (2:5) complexes binding uranium in an unidentate fashion. These species go through decarboxylation upon excitation to the triplet state, which ensues the release of CO<sub>2</sub> and reduction of U(VI) to U(V). The calculations also suggest an alternative intermolecular pathway at low pH via an electron transfer between the excited state *UO<sub>2</sub><sup>2+</sup> and hydrogen oxalate (HC<sub>2</sub>O<sub>4</sub><sup>-</sup>) which eventually leads to the production of CO and OH<sup>-</sup> with no net reduction of U(VI). The calculated results are consistent with previous experimental findings that CO is only detected at low pH while U(IV) is detected only at high pH.]]></dc:description>

<dc:date>2007</dc:date>
<dc:description><![CDATA[Atomic and electronic properties of the Mo6S8 cluster are investigated using DFT band structure calculations with pseudopotentials and a plane-wave basis set. The calculations showed that these clusters can be well bound on the surface in a potential well with degenerate local energy minima, despite a negligible net electron transfer between the two subsystems. The cluster may move freely inside this well on the surface. The cluster-surface binding is via S-Au bonds, with additional contributions of the Mo atom in the vicinity of the surface.]]></dc:description>

<dc:title><![CDATA[Steam bubble condensation in polydispersed flow - Experiments and CFD simulations]]></dc:title>
<dc:source><![CDATA[7th International Conference on Multiphase Flow, ICMF 2010, 30.05.-04.06.2010, Tampa, USA]]></dc:source>

<dc:description><![CDATA[Many activities were done in the last years to improve the modeling of adiabatic bubbly flows in the frame of CFD. In this case models for momentum transfer between the phases are most important. Usually they are expressed as so-called bubble forces. Experimental investigation as well as Direct Numerical Simulations (DNS) showed, that these bubble forces strongly depend on the bubble size. In addition to the well known drag force also virtual mass, lift, turbulent dispersion and wall forces have to be considered. The lift force even changes its sign in dependence of the bubble size (Tomiyama, 1989). In consequence large bubbles are pushed to the opposite direction than small bubbles if a gradient of the liquid velocity perpendicular to the relative bubble velocity exists (Lucas et al. 2001, Prasser et al. 2007). To simulate the separation of small and large bubbles more than one momentum equation is required (Krepper et al. 2005). For this reason recently so-called Inhomogeneous-MUSIG (MUlti SIze Group) model was implemented into the ANSYS-CFX code (Frank et al. 2008, Krepper et al. 2008). It allows the consideration of a number of bubble classes independently for the mass balance (for a proper modeling of bubble coalescence and breakup a large number of bubble groups is required) and for the momentum balance (only very few classes can be considered due to the high computational effort, criteria for the classification can be derived from the dependency of the bubble forces on the bubble size, e.g. the change of the sign of the lift force). In the presently implemented version of the Inhomogeneous MUSIG model only transfers between the bubble classes due to bubble coalescence and breakup can be modeled. In case of flows with phase transfer additional transfers between the single classes and the liquid and transfers between bubble classes caused by growth or shrinking of bubbles have to be considered. The equations for the extension of the MUSIG models are derived in Section 2. of this paper (see also Lucas et al. 2009). They were recently implemented into the CFX code and are presently verified (see Section 4).]]></dc:description>

<dc:date>2011</dc:date>
<dc:description><![CDATA[The interaction of uranium(VI) with carbonate ions was studied with absorption spectroscopy and time resolved laser induced fluorescence spectroscopy due to the importance of these complexes in environmental relevant waters. In the pH range from 2 to 11 the influence of the temperature on the spectra was studied to check changes in the abundances of several binding forms. It was found that several binding forms are predominant at different temperatures and pH values. This observation can be explained by speciation changes due to the dependence of chemical equilibria on the temperature. 
Furthermore photoluminescence spectra of aqueous solutions of uranyl carbonate complexes were observed at ambient temperatures for the first time and single component absorption spectra of the uranyl carbonate complexes UO2(CO3)34- and UO2(CO3)22- were derived.]]></dc:description>

<dc:description><![CDATA[In the multi-barrier concept for the deep geological disposal of high-level radioactive waste (HLW), bentonite is proposed as a potential barrier and buffer material for sealing the space between the steel-canister containing the HLW and the surrounding host rock. In order to broaden the spectra of appropriate bentonites, we investigated the metabolic activity and diversity of naturally occurring microorganisms as well as their time-dependent evolution within the industrial B25 Bavarian bentonite under repository-relevant conditions. We conducted anaerobic microcosm-experiments containing the B25 bentonite and a synthetic Opalinus Clay pore water solution, which were incubated for one year at 30 °C and 60 °C. Metabolic activity was only stimulated by the addition of lactate, acetate or H2. The majority of lactate- and H2-containing microcosms at 30 °C were dominated by strictly anaerobic, sulfate-reducing and spore-forming microorganisms. The subsequent generation of hydrogen sulfide led to the formation of iron-sulfur precipitations. Independent from the availability of substrates, thermophilic bacteria dominated microcosms that were incubated at 60 °C. However, in the respective microcosms, no significant metabolic activity occurred and there was no change in the analyzed bio-geochemical parameters.]]></dc:description>

<dc:description><![CDATA[Proton captures on Mg isotopes play an important role in the Mg-Al cycle active in stellar H shell burning. In particular, the strengths of low-energy resonances with E < 200 keV in 25Mg(p,gamma)26Al determine the production of 26Al and a precise knowledge of these nuclear data is highly desirable. Absolute measurements at such low-energies are often very difficult and hampered by gamma-ray background as well as changing target stoichiometry during the measurements.

<dc:date>2010</dc:date>
<dc:description><![CDATA[A combined experimental and theoretical study is presented revealing the influence of metal-molecule coupling on electronic transport through single-molecule junctions. Transport experiments through tolane molecules attached to gold electrodes via thiol, nitro, and cyano anchoring groups are performed. By fitting the experimental current-voltage characteristics to a single-level tunneling model, we extract both the position of the molecular orbital closest to the Fermi energy and the strength of the metal-molecule coupling. The values found for these parameters are rationalized with the help of density-functional-theory-based transport calculations. In particular, these calculations show that the anchoring groups determine the junction conductance by controlling not only the strength of the coupling to the metal but also the position of the relevant molecular energy levels.]]></dc:description>

<dc:description><![CDATA[A new macrocyclic ligand, 2-[4,7-bis(2-pyridylmethyl)-1,4,7-triazacyclononan-1-yl]acetic acid (1), binds copper strongly and the resulting radiocopper(II)-ligand complex exhibits high in vivo stability. The pendant carboxylic group enables this derivative to be conjugated to the N-terminal amino acid residues of peptides. Exploiting this, two stabilized bombesin derivatives have been coupled to 1 and radiolabeled with the positron emitter copper-64.
In vitro binding characteristics of the [64Cu]CuII-labeled bombesin conjugates in gastrinreleasing peptide receptor (GRPR) overexpressing prostate cancer (PC-3) cells have been evaluated. Biodistribution studies performed in Wistar rats indicate a specific uptake in the GRPR-rich pancreas and rapid renal elimination. Small animal PET imaging studies confirmed a high extent of tumor accumulation in NMRI nu/nu mice bearing the human prostate tumor PC-3. Incorporation of one additional glutamic acid residue within the spacer between bombesin and the radiolabeled complex leads to a higher tumor-to-muscle uptake ratio.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[In this paper detailed studies on modification of structural and magnetic properties of Ni-doped hafnium oxide (HfO2) thin films are reported. We used 200 keV Ni beam for doping of Ni. For homogeneous dispersion and activation of doped Ni ions, 120 MeV Ni swift heavy ions (SHI) irradiation was used. This unique combination of Ni doping by ion beam and dispersing and activating by Ni SHI irradiation of HfO2 films is reported for the first time. The origin of ferromagnetism in the Ni-doped HfO2 thin films is investigated. We demonstrate the cluster free nature of our film using cross-sectional high resolution transmission microscopy and magnetization versus temperature data. Rutherford backscattering data are used to establish that Ni ions are implanted in the HfO2 matrix at the predicted location. Dispersion of implanted Ni and lattice defects such as oxygen vacancies are attributed to be the main source of ferromagnetism.]]></dc:description>

<dc:description><![CDATA[Nanocomposites are heterogeneous materials wherein the lateral extension of at least one component is lower than 100 nm.[1] They represent a new class of functional materials, whose properties cannot be predicted from those of their constituents alone. Among the various classes of nanocomposites, metal-containing nano-particles embedded in a carbon matrix have recently attracted considerable interest regarding their structure and properties.[2,3] 
This study focuses on the structure and the mechanical properties of C:V nanocomposites. A series of C:V films with a varying vanadium concentration of 2 at.% ≤ xv ≤ 50 at.% was grown on silicon by DC dual magnetron sputtering. Depending on the metal concentration, significant structural variations were observed within both phases (dispersed phase and matrix) of the nanocomposite. At low vanadium concentrations, an amorphous metal rich and an amorphous carbon phase are formed. An increasing metal content promotes the formation of cubic VC and a graphitic carbon phase. With optimized deposition parameters, the hardness of the C:V nanocomposite films is higher then 10 GPa, and the elastic modulus achieves values of about 130 GPa. The friction coefficients for sliding conditions are as good as 0.1.

<dc:source><![CDATA[Chemical Geology 284(2011), 240-250]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[The U(VI) sorption onto Opalinus Clay (OPA), a natural clay rock from Mont Terri, Switzerland, was investigated in the absence and presence of humic acid under aerobic conditions using synthetic OPA pore water (I = 0.34 M, pH 7.6) as background electrolyte. The results show that the U(VI) sorption onto OPA is low and not influenced by humic acid. This can be attributed to the dissolution of calcite, a mineral constituent of the clay. The resulting calcium ions (up to 25 mM) in the pore water influence both the U(VI) speciation and the speciation of humic acid. In OPA pore water the U(VI) speciation is dominated by the neutral complex Ca2UO2(CO3)3(aq) both in the absence and presence of humic acid. Its predominance was verified by time-resolved laser-induced fluorescence spectroscopy (TRLFS). Speciation estimations for humic acid show that calcium ions saturate the humic acid binding sites almost completely. Thus, only few humic acid binding sites are available for U(VI) complexation at pH 7.6. For the sorption of U(VI) and humic acid onto OPA distribution coefficients, Kd, were determined and amount to (0.0222 ± 0.0004) m3/kg and (0.129 ± 0.006) m3/kg, respectively. In conclusion, calcium ions determine the interaction processes of U(VI) and humic acid in the OPA system.]]></dc:description>

<dc:description><![CDATA[It has been shown that increasing substrate temperature above its optimum value leads to an increase of Al concentration in the AZO films, which exceeds the solubility limit and triggers the formation of an insulating metastable homologous (ZnO)3Al2O3 phase. The formation of (ZnO)3Al2O3 is established for the AZO films grown in a given range of deposition conditions, while the films grown at substantially different conditions may show formation of other secondary phases (e.g. aluminium oxide or spinel). This (ZnO)3Al2O3 impedes crystal growth and causes a significant increase of free electron scattering. In turn, it leads to an increase of electrical resistivity of the films. This phase has been observed by XANES even in the films with the lowest Al concentration and the best crystallinity. Increase of this phase volume fraction with increasing Al concentration correlates with observed changes in the film Raman and optical constants spectra.]]></dc:description>

The new biosensor responds to picomolar levels of aqueous uranyl ions within minutes using Lysinibacillus sphaericus JG-A12 S-layer protein tethered to gold electrodes. In comparison to traditional self assembled monolayer based biosensors the porous bioconjugated layer gave greater stability, longer electrode life span and a denser protein layer. Biosensors responded specifically to UO2 2+ ions and showed minor interference from Ni2+, Cs+, Cd2+ and Co2+.

<dc:description><![CDATA[CaO and P2O5 containing Ti surfaces were prepared and examined for their bioactivity. The preparation involved the incorporation of Ca and P into Ti by ion implantation to a total dose of up to 8 x 1017 ions/cm² with a 1.7 Ca/P ratio and a subsequent oxidation at 500 °C in O2 for 40 min. The model surfaces were examined for their reactivity toward hydroxyapatite formation by microscopically recording the mineralization in a simulated body fluid. The ion implantation modified surfaces were shown to exhibit enhanced mineralization by inducing heterogeneous nucleation, growth, and proliferation of hydroxyapatite, relative to a control sample of pure Ti. The surface induced reactivity was shown to relate to the enhanced provision of the ionic mineral components Ca2+ and HPO42- directly supplied from the surface and the substrate-mediated nucleation by hydroxylated surface TiO2.]]></dc:description>

<dc:title><![CDATA[Marangoni convection in molten salts - physical modelling toward lower Prandtl numbers]]></dc:title>
<dc:source><![CDATA[Experiments in Fluids 50(2011)2, 479-490]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[Marangoni convection is involved in many technological processes. The substances of industrial interest are often governed by diffusive heat transport and their physical modelling is limited with respect to the Prandtl number Pr. The present paper addresses this deficiency. Studies were made on molten salts having Pr values in an intermediate range well below that of the typically employed organics. Since some of the selected species have a relatively high melting point, a high-temperature facility which allows studying thermocapillary convection at temperatures in excess of 1000°C was built. The results presented here were obtained in a cylindrical geometry, although the equipment that was built is not restricted to this configuration because of its modular construction. Modelled after some applications, the fluid was heated centrically on top. The bulk was embedded in a large thermostatically controlled reservoir so as to establish the lower ambient reference temperature. A characteristic size of the experimental cell was chosen such that, on the one hand, the dynamic Bond number Bo did not become too high; on the other hand, the liquid had to have a certain depth to allow particle image velocimetry. The complicated balance between body forces and thermocapillary forces in the case of intermediate Bo was found to result in a distinct local separation into a bulk motion governed by natural convection with a recirculating Marangoni flow on top. In contrast to low viscosity organics, the vapour pressure of which increases considerably with decreasing Pr, high values of the Marangoni number can be reached. Comparisons of the topology of Marangoni vortices between molten salts with 2.3 <= Pr <= 6.4 and a silicone oil with Pr typically one order of magnitude higher suggest that the regime of non-negligible heat diffusion is entered.]]></dc:description>

<dc:description><![CDATA[A two-beam laser deflection system has been setup for real-time measurement of the stress in thin films during processing. The curvature of a Si-cantilever, laser reflectivity and real time spectroscopic ellipsometry data are recorded simultaneously. Reliable real time film thickness data are essential for the calculation of the instantaneous stress from the bending force per unit width measured. Instantaneous stress data with a depth resolution in the nanometer range provide detailed information on growth processes. It is demonstrated that force per unit width or global stress data, as calculated by applying the simple form of Stoney's equation, are not appropriate for the analysis of the stress in layered structures like boron nitride films.
The depth distribution of the instantaneous stress in boron nitride films recorded during growth by ion beam assisted deposition has been analyzed. The layer sequence of interfacial turbostratic BN layer / mixed (t-BN+c-BN) transition layer / cubic BN can be clearly identified in the instantaneous stress data. The instantaneous stress has been found to depend sensitively upon fluctuations in the boron deposition rate which in turn cause variations in the ion/atom arrival ratio. Real time global stress data recorded during ion implantation into c-BN films have revealed for the first time two mechanisms being involved.

<dc:description><![CDATA[A systematic study on structural defect buildup in 320 keV Ar-ion bombarded GaN epitaxial layers has been reported, by varying ion fluences ranged from 5x10<SUP>12</SUP> to 1x10<SUP>17</SUP> at/cm<SUP>2</SUP>. 1μm thick GaN epitaxial layers were grown on sapphire substrates using the MOVPE technique. RBS\channeling with 1.7 MeV <SUP>4</SUP>He beam was applied for analysis. As a complementary method High Resolution Transmission Electron Microscopy (HRTEM) has been used. The later has revealed the presence of extended defects like dislocations, faulted loops and stacking faults. New version of the Monte Carlo simulation code McChasy has been developed that makes it possible to analyze such defects on the basis of the Bent Channel (BC) model. Damage accumulation curves for two distinct types of defects, i.e. Randomly Displaced Atoms (RDA) and extended defects (i.e BC) have been determined. They were evaluated in the frame of the MultiStep Damage Accumulation (MSDA) model, allowing numerical parameterization of defect transformations occurring upon ion bombardment. Displaced atoms buildup is a three step process for GaN and whereas extended defect buildup is always a two step process.]]></dc:description>

<dc:description><![CDATA[Die Strömung in der Metallschmelze hat einen wesentlichen Einfluss auf die Produktqualität beim Stranggießen. Probleme entstehen beispielsweise durch Einschlüsse von Oxiden, intermetallischen Verbindungen oder Gasblasen, die durch eine unkontrollierte Strömung in die Erstarrungszone gelangen. Die Optimierung dieser Strömung basierte bisher vor allem auf numerischen Simulationen und Modellexperimenten mit Wasser. Obwohl die Strömungsuntersuchungen an diesen Wassermodellen signifikante Erkenntnisgewinne über die Strömung und die optimale Auslegung z.B. des Tauchrohrs oder der Eintauchtiefe des Tauchrohrs gebracht haben, stoßen diese Modelle für eine Reihe von Fragestellungen an ihre physikalischen Grenzen, da Flüssigmetalle z.B. sehr hohe Oberflächenspannungen und sehr kleine Prandtl-Zahl besitzen, und Wasser offensichtlich für Untersuchungen des Einflusses von Magnetfeldern völlig ungeeignet ist.
In den vergangenen Jahren wurden am Forschungszentrum Dresden-Rossendorf experimentelle Versuchsanlagen mit niedrig schmelzenden Legierungen für die physikalische Modellierung des Stranggussprozesses aufgebaut. Ziel ist die systematische Untersuchung der Flüssigmetallströmungen und Transportprozesse in Verteiler, Tauchrohr und Kokille. Dabei steht insbesondere die Wirkung elektromagnetischer Felder, wie sie in Form von elektromagnetischen Bremsen oder Rührern bereits im industriellen Einsatz sind, im Mittelpunkt. Außerdem bieten die Versuchsanlagen gute Bedingungen für die Erprobung neuer Messtechniken und Anlagenkomponenten. Die Versuchsanlage CONCAST-LMM (Continuous Casting Liquid Metal Model) ist 2009 fertig gestellt worden und arbeitet mit einer Sn60Bi40-Legierung als Modellfluid im Temperaturbereich von 200°C bis 400°C. Ein kleineres Modell mit der eutektischen GaInSn-Legierung wird bei Raumtemperatur betrieben. Die Strömungseigenschaften werden mit Hilfe lokaler Sonden sowie modernen Ultraschall und elektromagnetischen Methoden vermessen. 
Im Rahmen dieses Beitrages werden Strömungsmessungen in einer einphasigen Flüssigmetallströmung in der Kokille unter Einwirkung eines statischen Magnetfeldes vorgestellt und mit entsprechenden numerischen Simulationen verglichen. Es zeigt sich, dass das Magnetfeld den aus dem Tauchrohr in die Kokille austretenden Jet ablenkt und lokale Rezirkulationsgebiete verstärkt. Die bremsende Wirkung des Magnetfeldes stellt sich als äußerst komplex dar. Eine gleichmäßige Reduktion der Strömungsgeschwindigkeit im gesamten Volumen wird nicht beobachtet.]]></dc:description>

<dc:date>1999</dc:date>
<dc:description><![CDATA[Abstract. 
The elastic backward proton-deuteron scattering is analyzed within a covariant approach based on the Bethe-Salpeter equation with realistic meson-exchange interaction. Contributions of the one-nucleon and one-pion exchange mechanisms to the cross section and polarization observables are investigated in explicit form. Results of numerical calculations for the cross section, tensor analyzing power and spin transfers are presented. The one-pion exchange contribution is essential for describing the spin averaged cross section, while in polarization observables it is found to be less important.]]></dc:description>

<dc:description><![CDATA[In the present contribution, high-resolution positron lifetime and coincidence Doppler broadening spectroscopies are used to characterize defects in Fe76Al24 and Fe72Al28 alloys. In order to facilitate defect identification, we also perform a theoretical study of basic vacancy-like defects in three phases of the FeAl system: ordered, short-range ordered, and disordered. Positron characteristics, like positron lifetime, positron binding energy to defects, high-momentum parts of Doppler broadening curves and specific trapping rates, are calculated for various defect configurations. The results are discussed in the context of experimental data obtained here and available in literature.]]></dc:description>

<dc:description><![CDATA[Understanding of the mechanisms of donor impurity incorporation, its electrical activation and charge carrier transport in transparent conducting oxides (TCO) is required for further improvement of functionality of this class of materials. The present work focuses on investigation of indium oxide (IO), Sn-doped indium oxide (ITO), ZnO, and ZnO:Al (AZO) films grown by reactive pulsed magnetron sputtering (RPMS) with a precise control of the oxygen partial pressure at substrate temperatures, Ts, ranging from RT to 550°C. In order to explore potential advantages of RPMS, the relationship between the deposition parameters and structure, phase composition and physical properties of these TCOs was investigated. The films were characterized by spectroscopic ellipsometry, Hall effect measurements, X-ray diffraction (XRD) and, in case of ZnO and AZO films, by X-ray absorption near edge structures (XANES). The Sn concentration in ITO was determined by Auger analysis, while the Al concentration in ZnO matrix was estimated by elastic recoil detection analysis and Rutherford back scattering.
The comparison of the real-time behavior of the IO and ITO film structure and electrical properties during annealing provides a direct evidence of Sn donor activation (with an estimated efficiency of 40%) in ITO due to amorphous-to-crystalline transition. The ITO film crystallinity always improves with increasing substrate temperature or during isothermal annealing, with the electrical resistivity decreasing. In contrast, the electrical resistivity of AZO films shows a clear minimum at an optimum substrate temperature (200-400 °C), which depends on metal/oxygen flux ratio and correlates with a maximum in crystallinity (grain size). In this case, the highest mobility value of 46 cm2 V-1 s-1 is comparable to the best values achieved in AZO films grown by less cost-efficient techniques. This value is achieved at the free electron density of 6x10<sup>20</sup> cm-3 which corresponds to maximum ~30% electrical activation of Al impurity. At higher temperatures, the AZO electrical properties and crystalline quality deteriorate abruptly according to the following mechanism. Increasing Ts above its optimum value leads to a higher Al concentration in the AZO films, which exceeds the solubility limit and triggers the formation of an insulating metastable homologous (ZnO)3Al2O3 phase. This phase impedes crystal growth and causes a significant increase of free electron scattering both at grain boundaries and inclusions of this phase. In order to enable the growth of low-resistivity AZO films in a wider range of TS, lower metal/oxygen flux ratios should be used. The proposed approach to minimizing the influence of this undesirable phase may also be applied to other deposition methods of AZO involving high-energy particle bombardment.]]></dc:description>

<dc:title><![CDATA[Arsenic speciation in sulfidic waters: Consolidation of contradictory spectroscopic and chromatographic evidence]]></dc:title>
<dc:source><![CDATA[Analytical Chemistry 82(2010)24, 10228-10235]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[In recent years, analytical methods have been developed that have demonstrated that soluble arsenic‐sulfur species constitute a major fraction of dissolved arsenic in sulfidic waters. However, an intense debate is going on about the exact chemical nature of these compounds, since X‐ray absorption spectroscopy (XAS) data generated at higher (mmol/L) concentrations suggest the presence of (oxy)thioarsenites in such waters, while ion chromatographic (IC) and mass spectroscopic data at lower (μmol/L to nmol/L) concentrations indicate the presence of (oxy)thioarsenates. In this contribution, we connect and explain these two apparently different types of results. We show by XAS that thioarsenites are the primary reaction products of arsenite and sulfide in geochemical model experiments in the complete absence of oxygen. However, thioarsenites are extremely instable towards oxidation, and convert rapidly into thioarsenates when exposed to atmospheric oxygen, e.g. while waiting for analysis on the chromatographic autosampler. This problem can only be eliminated when the entire chromatographic process is conducted inside a glove box. We also show that thioarsenites are instable towards sample dilution, which is commonly employed prior to chromatographic analysis when ultra‐sensitive detectors like ICP‐MS are used. This instability has two main reasons: if pH changes during dilution, then equilibria between individual arsenic‐sulfur species rearrange rapidly due to their different stability regions within the pH range, and if pH is kept constant during dilution, then this changes the ratio between OH‐ and SH‐ in solution, which in turn shifts the underlying speciation equilibria. This problem is avoided by analyzing samples undiluted. Our studies show that thioarsenites appear as thioarsenates in IC analyses if oxygen is not excluded completely, and as arsenite if samples are diluted in alkaline anoxic medium. This also points out that thioarsenites are necessary intermediates in the formation of thioarsenates.]]></dc:description>

<dc:title><![CDATA[The basic physics of intersubband transitions  from the simple to the subtle]]></dc:title>
<dc:source><![CDATA[International Quantum Cascade Lasers School & Workshop, 30.08.-03.09.2010, Florenz, Italien]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[I will describe the basic properties of intersubband transitions in quantum wells, partly along the lines of the now ten-years-old review paper [1]. I will proceed from the very basic to the discussion of some more specific systems, like superlattices or transitions within the valence band, and to some recently discovered, rather subtle effects.
 An interesting interplay is found with transitions between shallow impurity states, which becomes particularly striking in superlattices and coupled quantum wells [2]. Based on a calculation that treats the heterostructure potential and the random-impurity potential on the same footing [3], we can successfully explain or re-interpret some old, hitherto poorly understood data (see Fig. 1). 
Another subtle effect emerges, if intersubband spectra are recorded using time-domain terahertz spectroscopy, i.e. fully resolving the phase of the electric field. We show that transmission and absorption spectra are not equivalent, and whereas the absorption line has a standard Lorentzian shape, the transmission spectrum exhibits a Fano-type lineshape (see Fig. 2). This has been explained with the influence of the so-called ponderomotive current [4].
Most of the more recent experimental work discussed here was performed mainly by Dominik Stehr and Martin Wagner (both FZD), most of the samples used were provided by Gottfried Strasser (TU Vienna) and his group, and for part of this work the collaboration with the theory group of Univ. Marburg (D. Golde, M. Kira, S. W. Koch) was indispensable.

<dc:description><![CDATA[We have investigated low-temperature elastic properties of PrMg<sub>3</sub> with a non-Kramers Gamma<sub>3</sub> doublet ground state using ultrasonic measurements. Although the Gamma<sub>3</sub> doublet possesses electric quadrupoles O<sub>u</sub> and O<sub>v</sub> with Gamma<sub>3</sub>-symmetry and magnetic octupole T<sub>xyz</sub> with Gamma<sub>2</sub>, PrMg<sub>3</sub> reveals no sign of symmetry breaking long-range ordering down to 20 mK. [1] The elastic constant of (C<sub>11</sub>-C<sub>12</sub>)/2 in PrMg<sub>3</sub> exhibits remarkable softening below 8 K, which is well described in terms of a Curie-type quadrupole susceptibility for the Gamma<sub>3</sub> doublet. An appreciable upturn in (C<sub>11</sub>-C<sub>12</sub>)/2 below 800 mK in PrMg<sub>3</sub> may indicate an transition into an exotic ground state due to the quadrupole Kondo state being screened by conduction electrons. Frequency dependence in (C<sub>11</sub>-C<sub>12</sub>)/2 and its attenuation coefficients at low temperature in PrMg<sub>3</sub> suggests quadrupole fluctuations possessing a characteristic relaxation time tau = tau<sub>0</sub>exp(E/kT) with tau<sub>0</sub> = 6x10<sup>-11</sup> sec and an activation energy E = 410 mK. The low-temperature behavior in (C<sub>11</sub>-C<sub>12</sub>)/2 of PrMg3 under magnetic fields is also presented.]]></dc:description>

<dc:description><![CDATA[This paper reports on simulations of solid mass-limited targets (MLT) via electrodynamic 2D3V particle-in-cell simulations. The interaction with long (300 fs) high intensity (10<sup>20</sup> W/cm²) laser pulses with targets of diameter down to 1 m is described in detail with respect to electron dynamics and proton and ion acceleration. Depending on the foil diameter, different effects consecutively arise. Electrons laterally recirculate within the target, smoothening the target rear accelerating sheath and increasing the hot electron density and temperature. Our results suggest that the most significant ion energy enhancement to should be expected for MLT with diameter below the laser focal spot size. The spread of energetic protons is decreased for medium sized foils while it is greatly increased for foils of size near the focal spot size.]]></dc:description>

<dc:title><![CDATA[Experiments on the transport, deposition and resuspension of nuclear aerosols]]></dc:title>
<dc:source><![CDATA[International Aerosol Conference – IAC 2010, 29.08.-03.09.2010, Helsinki, Finnland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Nuclear aerosol deposition and the assessment of its resuspension during a design basis accident in the primary circuit are a key issue in the development and certification of advanced pebble bed High Temperature Reactors (HTRs). Nuclear aerosols, in particular graphite dust in size of d = [0.1; 50] μm, are deposited during operation in the primary circuit (Moormann (2008)). It is of general interest how much of these aerosols escape from the primary circuit into the containment during a depressurization scenario. The knowledge about the amount of resuspended dust allows the detailed estimate of the dose escaping the primary circuit
Flow conditions in the primary circuit range from laminar flows in the recuperator till turbulent high Reynolds number flows in the pipes and ducts. Considering the particle size distribution published by Moormann (2008), particle Stokes numbers will range from very small Stk << 1 till moderately high Stk > 1. In order to investigate the fluid mechanic behavior between the flow and the aerosol within the set of characteristic numbers, we designed a small scale gas aerosol test facility (Figure 1).

We found a turbulent square duct flow most suitable because all the flow features such as streamwise and spanwise velocity gradients, as well as vortical structures are apparent. Furthermore, there will be a wide range of experimental and numerical data for comparison.
The test facility is a small scale wind tunnel in total length of 6 m with a 10 x 10 cm² square duct section. A 500 W radial fan at the outlet of the channel accelerates the flow field from 0 up to 7.5 m/s which is equivalent to a Reynolds number of about Re = 50 k.
The inlet is equipped with a HEPA filter to clean the incoming air. A nozzle contracts the flow into a square duct which is divided into a flow formation zone (15 x d) and a test section (5 x d). In the beginning of the flow formation zone the dust feeder or the aerosol generator injects the aerosol. The length of 15 x d for the flow formation zone ensures that the test section is streamed by a well developed turbulent channel flow with an evenly distributed aerosol. Both, test section and flow formation zone, are made of transparent acrylic glass to allow optical flow field measurements, such as PIV, high speed camera imaging for the analysis of the flow field and microscopic imaging techniques for the surface particle detection.
A diffusor stage decelerates the flow before it enters the electrostatic filter for air cleaning purposes. Finally, the 500 W radial fan produces the pressure drop for the desired flow speed.
Preliminary measurements of total pressure drop in the square duct section and time averaged mean center velocity profiles for different Reynolds number will be presented on the poster.]]></dc:description>

<dc:title><![CDATA[Prediction of polydisperse steam bubble condensation in sub-cooled water using the Inhomogeneous MUSIG model]]></dc:title>
<dc:source><![CDATA[CFD4NRS-3, Workshop on Experimental Validation and Application of CFD and CMFD Codes to Nuclear Reactor Safety Issues, 14.-16.09.2010, Washington D.C., USA]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The aim of this paper is to present the validation of a new methodology implemented in ANSYS CFX  (ANSYS, 2009), that extends the standard capabilities of the inhomogeneous MUltiple-SIze Group model (MUSIG) by additionally accounting for bubble size changes due to heat and mass transfer.  Bubble condensation plays an important role in sub-cooled boiling or steam injection into pools among many other applications of interest in the Nuclear Reactor Safety (NRS) area and other engineering areas. Since the mass transfer rate between phases is proportional to the interfacial area density, a polydisperse modelling approach considering different bubble sizes is of main importance, because an accurate prediction of the bubble diameter distribution is required. 
The standard MUSIG approach is an inhomogeneous one with respect to bubble velocities, which combines the size classes into different so-called velocity groups to precisely capture the different behaviour of the bubbles depending on their size. In the framework of collaboration between ANSYS and the Forschungszentrum Dresden-Rossendorf (FZD) an extension of the MUSIG model was developed, which allows to take into account the effect of mass transfer due to evaporation and condensation on the bubble size distribution changes in addition to breakup and coalescence effects. 
After the successful verification of the model, the next step was the validation of the new developed model against experimental data. For this purpose an experiment was chosen, which was investigated in detail at the TOPFLOW test facility at FZD. It consists of a steam bubble condensation case at 2MPa pressure in 3.9K sub-cooled water at a large diameter (DN200) vertical pipe. Sub-cooled water flows into the 195.3 mm wide and 8 m height pipe, were steam is injected at z=0.0 m and is recondensing. The experimental results are published in (Lucas, et al., 2007). Using a wire-mesh sensor technique the main characteristics of the two-phase flow were measured, i.e. radial steam volume fraction distribution and bubble diameter distribution at different heights and cross-sections. 
ANSYS CFX 12.0 was used for the numerical prediction. A 60 degrees pipe sector was modelled in order to save computational time, discretized into a mesh containing about 260.000 elements refined towards the pipe wall and towards the location of the steam injection nozzles. Interfacial forces due to drag, lift, turbulent dispersion and wall lubrication force were considered. The numerical results were compared to the experimental data. The agreement is highly satisfactory, proving the capability of the new MUSIG model extension to accurately predict such complex two-phase flow.]]></dc:description>

results are compared with purely ballistic simulations of the deposition process using the TRIYDN4.0 code. It is found that the intermixing of adjacent layers must be decribed in terms of ballistic mixing followed
by chemical mixing. The phase build-up in the transition layer between adjacent layers follows the non-equilibrium behaviour of Fe/Al in analogy to investigations on mechanically alloyed and ion-beam mixed Fe/Al. In
Fe-rich areas a bcc-solid-solution is formed. In Al-rich environment an amorphous phase is observed.]]></dc:description>

<dc:description><![CDATA[At the Forschungszentrum Dresden-Rossendorf (FZD), the Light Water Reactor (LWR) dynamics code DYN3D is extended and adopted for the application to block-type High temperature gas-cooled reactor (HTGR). DYN3D is a two-group diffusion code for 3D steady-state and transient core calculations based on nodal expansion methods. In addition to the neutron kinetics, it disposes of a thermal-hydraulics model for flow in parallel coolant channels. Macroscopic cross section data libraries precalculated with variation of burn-up, reactor poisons concentrations and thermal-hydraulic feedback parameters are linked to the code. Recently, a multi-group version of the code was developed.
In this paper, we give an overview of the latest developments of DYN3D concerning block-type HTGR.
The SP3 transport approximation is implemented into the multi-group DYN3D code to take anisotropy of the neutron flux and heterogeneity of the core more precisely into account. The SP3 method previously implemented into DYN3D for square fuel element geometry of LWR is being extended for hexagonal geometry of the graphite blocks, where the hexagons are subdivided into triangular nodes to be able to perform a systematic mesh refinement.
The main challenge in cross section generation for the HTGR core calculations is the treatment of the so-called double heterogeneity. The Reactivity equivalent Physical Transformation (RPT) approach is applied in order to eliminate the double-heterogeneity of HTGR fuel elements in HELIOS calculations. The full core analysis of the reference simplified HTGR core is performed with DYN3D using macroscopic nodal cross sections provided by HELIOS. The DYN3D results are verified against full core Monte Carlo simulations. 
A 3D heat conduction module coupled with a channel-type coolant flow model is implemented to take into account the temperature reactivity feedback to neutronics physically correctly. It is shown that there is significant redistribution of the produced heat by heat conduction between the graphite blocks.]]></dc:description>

<dc:source><![CDATA[Physical Review C, Vol. 62, 014313]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[Rotational bands in 73Br have been investigated 
up to spins of 65/2 using the EUROBALL 
III spectrometer. One of the 
negative-parity bands displays the highest rotational 
frequency 1.85 MeV reported to date in nuclei heavier than 25.
At high frequencies, the experimental dynamic moment of inertia  for all bands decrease to very low values,  indicating
a lose of collectivity. The bands are described in the configuration-dependent cranked 
Nilsson-Strutinsky model. The calculations indicate that 
one of the negative-parity bands is observed up to its terminating single-particle state at spin 63/2. 
This result establishes the first band termination in the 
A =70 mass region.]]></dc:description>

<dc:source><![CDATA[Workshop on Numerical Simulations of MHD flows, 18.-20.10.2010, Karlsruhe, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Numerical simulations of the electromagnetic induction equation are carried out applying a grid based finite volume method where insulating boundaries are treated by the boundary element method. A prescribed flow of liquid sodium provides the energy source for self-generation of a magnetic field and the influences of non-uniform material properties on the induction process are examined by means of internal assemblies and outer container walls with high conductivity or high permeability.

High permeability material even if localized in a small volume like the flow driving impellers in the French VKS dynamo experiment, essentially determines the field generation process (decrease of the effective critical magnetic Reynolds number and enforcing of internal boundary conditions on material interfaces). Permeability caused facilitation of dynamo action might be important as well for the helical flow in cooling circuits of fast breeders. Preliminary simulations for a model flow in and around soft-iron sub-assemblies (that comprise the nuclear fuel pins) show a reduction of the critical magnetic Reynolds number for the onset of dynamo action by a factor of 2.

The third examined configuration is motivated by an application of the contactless inductive flow tomography (CIFT) in a continuous casting model experiment. Consideration of the finite conductivity of the copper container walls results in a quantitative modification of the current distribution within the solid material. An enhanced current yields an amplified induced magnetic field outside of the container which must be considered in the reconstruction of the fluid velocity field.]]></dc:description>

<dc:description><![CDATA[Atomistic computer simulations based on the binary collision approximation (BCA) are very well suited to predict the dependence of as-implanted dopant profiles on implant parameters like energy, dose and direction of incidence as well as on the arrangement of oxide, poly-Si and other materials on the single-crystalline Si substrate. In particular channeling effects, the enhanced dechanneling due to accumulation of radiation defects during ion bombardment and due to preexisting ion-beam-induced defects can be simulated in a reasonable manner. The BCA code Crystal-TRIM was successfully integrated into 1D and 2D process simulators for the Si technology. The application of the trajectory splitting algorithm and the lateral duplicatioin method ensures a high computational efficiency.]]></dc:description>

<dc:description><![CDATA[High doses of 350 keV Al+ ions were implanted into 6H-SiC single crystals at 500oC. The phase formation was studied by TEM, SIMS and AES. A critical Al concentration of about 10 at% was found below that the 6H-SiC structure remains stable. The Al atoms
occupy preferentially Si sites in the SiC lattice. The replaced Si atoms seem to be mobile under the given implantation conditions and diffuse out. At higher Al concentrations the SiC matrix is decomposed and precipitates of Si and Al4C3 are formed.
It was found that the Al4C3 precipitates have a perfect epitaxial orientation to the SiC matrix. The phase transformation is accompanied by atomic redistribution and strong volume swelling. The resulting changes in the atomic profiles can be accounted
for by a simple chemical reaction model.]]></dc:description>

<dc:source><![CDATA[Wissenschaftlich-Technische Berichte / Helmholtz-Zentrum Dresden-Rossendorf; FZD-537 2010<br>ISSN: 1437-322X]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Die vorliegende Arbeit entstand im Rahmen einer Kooperation des Forschungszentrums Dresden-Rossendorf mit Qimonda Dresden GmbH & Co. OHG. Mithilfe der hochauflösenden Rutherford-Streuspektrometrie (HR-RBS) wurden das Diffusionsverhalten und Schichtwachstum von ZrO2 auf SiO2 und TiN im Anfangsstadium untersucht. Auf Grund der exzellenten Tiefenauflösung von 0,3 nm an der Oberfläche stand die Analyse von Konzentrationsprofilen in ultradünnen Schichten, respektive an deren Grenzflächen im Vordergrund.
Zur qualitativen Verbesserung der Messergebnisse wurde erstmals ein zweidimensionaler positionsempfindlicher Halbleiterdetektor in den Aufbau der HR-RBS implementiert und charakterisiert. Außerdem wurde ein Messverfahren in Betrieb genommen, das mögliche Schädigungen durch den Ioneneintrag in die Messprobe minimiert. Durch die Optimierung der experimentellen Bedingungen und die Entwicklung eines Programmpaketes zur Unterstützung des Analysten konnte ein effizienter Routine-Messablauf erstellt werden.
Im Moment einer binären Kollision zwischen einfallendem Ion und Targetelement kommt es bei kleinem Stoßparameter zu Veränderungen des Ladungszustands der gestreuten Ionen, insbesondere durch die abrupte Geschwindigkeitsänderung des Projektils und der Überlappung der Elektronenwolken. Bei der HR-RBS mit Energie separierendem Dipolmagneten muss zur Interpretation von Streuspektren die Ladungszustandsverteilung der gestreuten Projektile bekannt sein. Erstmalig konnte eine signifikante Abhängigkeit der Ladungszustandsverteilung gestreuter C-Ionen sowohl von der Schichtdicke als auch der Ordnungszahl des detektierten Targetelements, hier der vierten Nebengruppe, nachgewiesen werden.
Diese gewonnen Erkenntnisse ermöglichten systematische Untersuchungen zum ZrO2-Schichtwachstum im Anfangsstadium. Zur Herstellung der ZrO2-Schichten wurde die Atomlagenabscheidung (ALD) verwendet. Anhand der nachgewiesenen Agglomeration von ZrO2 auf nativen SiO2 wurde mithilfe der Rasterkraftmikroskopie (AFM) zur Bestimmung von Oberflächenrauigkeiten eine Methode konzipiert, welche die Auswirkung lokaler Schichtdickeninhomogenitäten auf die niederenergetische Flanke eines Streuspektrums berücksichtigt. Auf dieser Grundlage durchgeführte Simulationsrechnungen ergeben, dass keine Diffusion von Zr in die darunter liegende Schicht stattfand, jedoch eine ZrSiO4-Grenzflächenschicht existiert. Für das Wachstum von ZrO2 auf TiN wird aus den hoch aufgelösten Streuspektren ein völlig anderes Verhalten abgeleitet. Messungen zu Oberflächentopografien der TiN-Schicht liefern nicht zu vernachlässigende Werte für die Rauigkeit. Um den Einfluss der Oberflächenrauigkeit auf die Form des hoch aufgelösten Spektrums erfassen zu können, wurde eine Software entwickelt. Auf Basis von AFM-Messungen ermöglicht dieses Programm das Extrahieren einer Energieverteilung aus den Weglängen von ausschließlich an der Oberfläche gestreuten Ionen. Unter Berücksichtigung des Effekts der Oberflächenrauigkeit auf die HR-RBS Spektrenform konnte die Diffusion von Zr in das polykristalline TiN erstmals verifiziert werden. Die Beobachtungen weisen daraufhin, dass bereits nach dem ersten ALD-Zyklus ein geringer Anteil der deponierten Zr-Atome bis in eine Tiefe von etwa 3 nm in das TiN diffundiert. Die vorläufigen Ergebnisse legen Korngrenzendiffusion nahe.]]></dc:description>

<dc:description><![CDATA[Metals that form dense native surface oxide layers challenge plasma diffusion treatment techniques. Experimental results obtained during nitriding of stainless steel from real-time depth-resolved compositional analysis by elastic recoil detection give insight into the transport kinetics. In agreement with semi-quantitative considerations on the oxide removal and the oxide growth, the interplay of sputtering and oxidation emerges as a key parameter. On this background, suggestions for practical applications and optimization of the modification processes are given for different plasma diffusion treatment techniques.]]></dc:description>

<dc:source><![CDATA[Materials and Corrosion 50, 162-165 (1999)]]></dc:source>
<dc:date>1999</dc:date>
<dc:description><![CDATA[High oxidation resistance of gamma titanium aluminides can be achieved by the formation of a continuous scale of slowly growing Al2O3. The formation of such a scale was stimulated by the addition of small amounts of chlorine. The additions were incorporated by ion implantation into the sample. The g-TiAl samples were oxidized at 1173 K in air for 100 h. Even if chlorine is present in very small quantities, it has a highly beneficial effect on the oxidation resistance (microalloying effect). The kinetics are changed from mixed TiO2/Al2O3- kinetics for unimplanted specimens to pure Al2O3- kinetics for chlorine implanted specimens.]]></dc:description>

<dc:description><![CDATA[The production of laser-accelerated, high energy and high current particle beams requires a proper shielding assessment, especially when high intensity laser systems operate in repetition rate. The ELI (Extreme Light Infrastructure) future european facility in Czech Republic, where different optional laser beamlines are foreseen, will offer versatile electron and proton/ion sources, emitting in an unprecedented energy range (up to about 40 GeV for the electron case). For this facility a first extensive study that includes shielding and activation calculations for the 300 J laser beamline, which is the most critical for electron acceleration experiments, has been performed. Starting from analytical calculations, as well as from dedicated simulations, the main radiation fields produced in the laser-matter interaction have been defined. These fields have been then characterized as "source terms" in a full simulation with the Monte Carlo code FLUKA, where the produced secondary radiation has been studied to assess a proper shielding. The first results for the ELI shielding for the electron case, together with the activation calculations that drove several material solutions, are here presented and discussed.]]></dc:description>

Futhermore, the two executed air/water measurement series were specified. On the one hand, the behaviour of the flow through an Emergency Core Cooling (ECC) line into a Cold Leg of a Pressurized Water Reactor was investigated in dependence on some thermo hydraulic parameters. On the other hand, the occureance of thermal stratification inside the Cold Leg during ECC injection with different mass flows was analysed. An explanation of the next steps for the steam/water tests and an outlook completed the presentation.]]></dc:description>

<dc:description><![CDATA[Cyclin-dependent kinases 4 and 6 (Cdk4/6) are important components of cell cycle activation and control in early G<SUB>1</SUB> phase. Both enzymes and their regulators, e.g., cyclins, play critical roles in embryogenesis, homeostasis, and cancerogenesis. Cdk4/6 are attractive targets for cancer treatment. Recently, numerous selective small molecule inhibitors of Cdk4/6 have been developed. The potential of Cdk4/6 inhibitors, particularly, pyrido[2,3-d]pyrimidine derivatives, as both anti-cancer drugs and <SUP>124</SUP>I- and <SUP>18</SUP>F-radiolabeled tracers for cancer imaging using positron emission tomography is discussed.]]></dc:description>

<dc:description><![CDATA[DYN3D is an advanced nodal code for the three-dimensional steady-state and transient analysis of LWR cores with quadratic and hexagonal fuel assemblies. Although a new version of DYN3D for the simulation of block type High Temperature Gas cooled Reactors (HTGR) is currently under development, the main objective of this work is to demonstrate the applicability of the standard DYN3D version for the steady-state analysis of HTGR core. A preliminary reactor physic analysis procedure in which few group cross section sets are generated using HELIOS 1.9 transport lattice code and full core calculations are performed by DYN3D will be established. The Reactivity equivalent Physical Transformation (RPT) approach will be applied in order to eliminate the double-heterogeneity of HTGR fuel elements in HELIOS calculations. The full core analysis of the reference simplified HTGR core will be performed with DYN3D using macroscopic nodal cross sections provided by HELIOS. At this stage thermo-hydraulic feedback is not considered. The results of DYN3D calculations such as neutron multiplication factor, radial and axial power distribution, will be compared with those obtained from reference full core MCNP simulation.]]></dc:description>

<dc:source><![CDATA[Applied Physics A 71 (2000) 175-180]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[The lattice damage of silicon produced by ion implantation at extremely high  current  density of 0.8 A/cm<SUP>2</SUP> (2.5 x 10<SUP>18</SUP> cm<SUP>-2</SUP> s<SUP>-1</SUP>) was investigated.  In a focused ion beam system, implantation  was carried out with  70 keV Co ions, fluences of 1.2 x 10<SUP>16</SUP> cm<SUP>-2</SUP> and 6.7 x 10<SUP>15</SUP> cm<SUP>-2</SUP> into Si (111) at room temperature and elevated temperatures between 355 °C and 400 °C. Radiation damage measurements were performed by Rutherford backscattering/channeling spectroscopy and micro-Raman analysis. The radiation damage was studied as a function of pixel dwell-time and implantation temperature. The critical temperature for amorphization  increases with current density. Although the fluence of the focused ion implantation was constant, crystalline layers were obtained for short and amorphous layers for long pixel dwell-times. The critical dwell-time of crystalline/amorphous transition increases with implantation temperature. From the results a typical time for defect annealing of 10<SUP>-5</SUP> s at 400 °C and an activation energy of (2.5±0.6) eV were deduced.]]></dc:description>

<dc:description><![CDATA[Mit Hilfe von QCD-Summenregeln untersuchen wir die Sensitivität von pseudoskalaren Mesonen bestehend aus einem leichten und einem schweren Quark (D, D_s und B) auf das chirale Kondensat und betrachten mögliche Verschiebungen oder Aufspaltungen der Massen (d.h. Änderungen der Spektralfunktionen) von Teilchen und Antiteilchen unter Annahme einer linearen Dichteabhängigkeit der Kondensate.
Um Systeme mit direkterer Abhängigkeit vom chiralen Kondensat zu untersuchen, betrachten wir Weinberg-Kapusta-Shuryak Summenregeln bei endlichen Dichten im schwer-leicht Sektor.
Die besondere Rolle der Gluonenkondensate in Systemen aus zwei schweren Quarks (z.B. J/psi) und deren Beziehung zur QCD Spur Anomalie ermöglicht eine Erweiterung der Methode der QCD Summenregeln auf Temperaturen nahe T_c. Unter Verwendung des Rossendorfer Quasi-Teilchen-Modells bestimmen wir die Temperaturabhängigkeit des Digluonen-Kondensats bei endlichen Baryondichten nahe T_c und diskutieren deren Auswirkung auf das J/psi.]]></dc:description>

<dc:source><![CDATA[Microelectronic Engineering 48 (1999) 231-234]]></dc:source>
<dc:date>1999</dc:date>
<dc:description><![CDATA[This paper reports on self-organization of narrow bands of Ge nanoclusters in thin thermally grown SiO<SUB>2</SUB> layers by means of ion beam synthesis. Although the implanted Ge profile is distributed over almost the whole SiO2, a delta-like nanocluster band very close to, but well separated from the Si/SiO<SUB>2</SUB> interface is formed under specific implantation and annealing conditions. The evolution of this band can be explained by a model taking into account collisional ion beam mixing and reactions near the Si/SiO<SUB>2</SUB> interface, which describes in good agreement the experimental results. The reliable fabrication of such cluster bands are the basis for new memory applications.]]></dc:description>

<dc:source><![CDATA[Annals of Nuclear Energy 26 (1999) 1331-1339]]></dc:source>
<dc:date>1999</dc:date>
<dc:description><![CDATA[Subsequent studies have identified many scenarios which can lead to reactivity excursions due to boron dilution. The comparative study, presented in this paper, deals with the so-called "restart of the first reactor coolant pump" scenario and its reactor-dynamic consequences for the both VVER reactor types - VVER-440 and VVER-1000. The transient simulations were performed using the three-dimensional core dynamics code DYN3D. The DYN3D modeling features, including recent developments, as well as the cross-section generation methodology, involved in these calculations, are described. The analyzed accident scenario is outlined together with the assumptions made. The results of core response in this boron dilution accident for both VVER reactors have been compared within ranges, determined by the two reactivity values of interest: the criticaly limit and the reactivity initiated accident (RIA) limit.]]></dc:description>

<dc:source><![CDATA[30th International Conference on the Physics of Semiconductors (ICPS), 25.-30.07.2010, Seoul, Korea]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The discovery of superconductivity in heavily boron-doped diamond [1] has demonstrated that group-IV semiconductors can become superconducting upon carrier doping even at ambient conditions. Meanwhile superconductivity has been found in further heavily doped group-IV semiconductors such as Si and SiC [2]. Compared to these semiconductors, Ge seems to be less promising for realizing superconductivity as was based upon estimates of the electron-phonon coupling strength [3]. The challenge is to achieve extremely high hole concentrations which are commonly limited by the equilibrium solid solubility of the acceptor. Nevertheless, we succeeded in making Ge superconducting as recently reported [4]. A nonequilibrium doping process consisting of 100 keV Ga+-ion implantation with a fluence of 21016cm-2 and subsequent 3 ms flash-lamp annealing (FLA) enabled hole concentrations as high as 1.41021 cm-2. The superconducting state was observed in a thin (~60 nm) Ge layer with a maximum Ga content of about 8 at.% at critical temperatures below 0.5 K. From the measured critical parameters it follows that Ga-doped Ge is a type-II superconductor with a large Ginzburg-Landau parameter (>103).
The structure as well as the superconducting properties of the Ga-doped Ge layers depend sensitively on the preparation conditions as shown in Fig. 1. In search for higher transition temperatures, implantation and annealing conditions were varied in a more comprehensive study. Critical temperatures above 1 K were obtained for samples either implanted with 41016 cm-2 and flash-lamp annealed at 52 Jcm-2 or implanted with 21016 cm-2 and subjected to rapid thermal annealing (RTA) at 910°C for 60 s (Fig. 2). Critical magnetic fields perpendicular and parallel to the Ge:Ga plane up to about 0.3 and 1 T, respectively, were observed. Thus superconductivity in thin Ge:Ge layers is a robust effect and could be utilized in superconducting quantum devices.

<dc:description><![CDATA[The influence of the high current density of a focused ion beam on the ion beam synthesis of CoSi2 layers has been investigated. After 35 keV Co+ or 70 keV Co2+ implantation into a heated Si(111) substrate and subsequent annealing, the layers have been investigated by scanning electron microscopy and Rutherford backscattering spectroscopy. It is shown that the mode of beam scanning influences the CoSi2 layer formation significantly. At a given substrate temperature, a sufficient low dwell-time is required to obtain a continuous layer rather than a laterally disrupted structure. With increasing target temperature, the dwell-time window becomes less restricted. The results are discussed in terms of  damaging and dynamic annealing of the silicon crystal. RBS/channeling investigations demonstrate that continuous or disrupted CoSi2 layers are formed when the substrate remains crystalline or becomes amorphous, respectively.]]></dc:description>

<dc:description><![CDATA[The organometallic precursor (NEt<SUB>4</SUB>)<SUB>2</SUB>[ReBr<SUB>3</SUB>(CO)<SUB>3</SUB>] was reacted with bidendate dithioethers (L) of the general formula H<SUB>3</SUB>C-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-R (R = -CH<SUB>2</SUB>CH<SUB>2</SUB>COOH, CH<SUB>2</SUB>-C=CH) and R'-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-R' (R' = CH<SUB>3</SUB>CH<SUB>2</SUB>-, CH<SUB>3</SUB>CH<SUB>2</SUB>-OH, CH<SUB>2</SUB>COOH) in methanol to form stable rhenium(I) tricarbonyl complexes of the general composition [ReBr(CO)<SUB>3</SUB>L]. Under these conditions the functional groups do not participate in the coordination. As a prototypic representative of this type of Re compounds the propargylic-group-bearing complex [ReBr(CO<SUB>3</SUB>)(H<SUB>3</SUB>C-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>C=CH)] Re<SUB>2</SUB> was studied by X-ray diffraction analysis. Its molecular structure exhibits a slightly distorted octahedron with facial coordination of the carbonyl ligands. 
The potentially tetradentate ligand HO-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-OH was reacted with the trinitrato precursor [Re(NO<SUB>3</SUB>)<SUB>3</SUB>(CO)<SUB>3</SUB>]<SUP>2-</SUP> to yield a cationic complex [Re(CO)<SUB>3</SUB>(HO-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-OH)]NO<SUB>3</SUB>  Re8 which shows the coordination of one hydroxy group. Re8 has been characterized by correct elemental analysis, infrared spectroscopy, capillary electrophoresis and X-ray diffraction analysis.

The X-ray structure analysis of the complex [Re(CO)<SUB>3</SUB>(OOC-CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>-COOH)] Re6 shows the second carboxylic group non-coordinated offering an ideal site for functionalization or coupling a biomolecule.
The no-carrier-added preparation of the analogue <SUP>99m</SUP>Tc(I) carbonyl thioether complexes could be performed using the precursor fac-[99mTc(H<SUB>2</SUB>O)<SUB>3</SUB>(CO)<SUB>3</SUB>]<SUP>+</SUP>

In saline, the chromatographically separated compound was stable for at least 120 min.

The cationic charge of the conversion product was confirmed by capillary electrophoresis. By the introduction of a carboxylic group into the thioether ligand as a third donor group the conversion could be suppressed and thus the neutrality of the complex preserved. 
Biodistribution studies in the rat demonstrated for the neutral complexes [<SUP>99m</SUP>TcCl(CO)<SUB>3</SUB>(CH<SUB>3</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>3</SUB>)] Tc1 and [<SUP>99m</SUP>TcCl(CO)<SUB>3</SUB>(CH<SUB>2</SUB>-S-CH<SUB>2</SUB>CH<SUB>2</SUB>-S-CH<SUB>2</SUB>-C=CH)] Tc2 a significant initial brain uptake (1,03 ± 0.25 % and 0.78 ± 0.08 % ID/organ at 5 min. p.i.).

<dc:description><![CDATA[We have conducted systematic experimental studies of  K<sup>+</sup> and K<sup>-</sup> production and propagation in nucleus-nucleus collisions at beam energies close to and below the production threshold for free nucleon-nucleon (NN) collisions. In noncentral Au+Au collision, the  K<sup>+</sup> mesons are preferentially emitted perpendicular to the reaction plane and the excitation functions for K<sup>+</sup> and K<sup>-</sup> mesons nearly coincide when correcting for the threshold energy. In contrast, for NN collisions the K<sup>+</sup> yield exceeds the K<sup>-</sup> yield by two orders of magnitude near the respective NN threshold. Both effects are considered to be experimental signatures of a modification of kaon properties in the nuclear medium.]]></dc:description>

<dc:description><![CDATA[The presence of current pulses superimposed on the dc level of the ion current in liquid metal ion sources has been known for a long time. This work investigates the behaviour of the pulses for varying temperature and working liquid metal. Attempts are made to explain the differences observed in the threshold current for the appearance of the pulses and also in their terminal, or saturation, frequency. Differences are also found between sources using the same working metal, although the pulse appearance threshold current is the same for a given metal. 
The experimental results indicate that a low source operating temperature is desirable if droplet emission is to be minimized.]]></dc:description>

<dc:description><![CDATA[Thin films of Ba3Ca1.18Nb1.82O8.73, prepared in a sol-gel process by multiple dip-coating on silicon wafers were charged with hydrogen by dissociative water
absorption at definite values of water vapour pressures and temperatures. The hydrogen content was determined using nuclear resonance reaction analysis. From the resulting water vapour pressure/hydrogen composition isotherms the absorption enthalpies and the absorption entropy were calculated in the framework of a two site
model, based on Fermi-Dirac statistics. On Ba3Ca1.18Nb1.82O8.73 also impedance spectroscopy was performed yielding the bulk conductivity. From these data
in combination with proton transport numbers and the thermodynamic results as noted above the proton diffusion coefficient could be evaluated.

<dc:date>2010</dc:date>
<dc:description><![CDATA[Nominally undoped, hydrothermally grown ZnO single crystals have been investigated prior to and after doping in remote H plasma. Characterizations have been made by temperature-dependent Hall effect (TDH) and low temperature photoluminescence (PL) measurements. The H content before and after the doping has been de-termined using nuclear reaction analysis and is compared to the density of shallow donors derived from the TDH measurements. 
The electrical properties of the as-grown ZnO sin-gle crystals are found to differ significantly. This is as-cribed to the density ratio of shallow donors and compen-sating acceptors. PL measurements showed that AlZn, GaZn, and interstitial zinc (Zni) are prominent shallow donors in the as-grown samples.
Remote H plasma treatment produced a metallic conducting near-surface layer thus masking the electrical properties of the bulk. The electrical properties of the in-vestigated samples are very similar after the treatment, independent of the as-grown state, because the density of shallow donors far exceeds that of compensating accep-tors in the affected near-surface region. The maximum of the broad near-band-edge emission is found to be located at 3.3595 eV due to the high doping density.]]></dc:description>

<dc:source><![CDATA[International Journal of Developmental Neuroscience 28(2010), 31-38]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Traumatic brain injury is a leading cause of death and disability in children. Studies using adult animal models showed alterations of the central cholinergic neurotransmission as a result of trauma. However, there is a lack of knowledge about consequences of brain trauma on cholinergic function in the immature brain. It is hypothesized that trauma affects the relative acetylcholine esterase activity and causes a loss of cholinergic neurons in the immature brain. Severe fluid percussion trauma (FP-TBI, 3.8  0.3 atm) was induced in 15 female newborn piglets, monitored for 6 h and compared with 12 control animals. The hemispheres ipsilateral to FP-TBI obtained from seven piglets were used for acetylcholine esterase istochemistry on frozen sagittal slices, while regional cerebral blood flow and oxygen availability was determined in the remaining eight FP-TBI animals. Post-fixed slices were immunohistochemically labelled for choline acetyltransferase as well as for lowaffinity neurotrophin receptor in order to characterize cholinergic neurons in the basal forebrain. Regional cerebral blood flow and brain oxygen availability were reduced during the first 2 h after FPTBI (P < 0.05). In addition, acetylcholine esterase activity was significantly increased in the neocortex, basal forebrain, hypothalamus and medulla after trauma (P < 0.05), whereas the number of choline acetyltransferase and low-affinity neurotrophin receptor positive cells in the basal forebrain were unaffected by the injury. Thus, traumatic brain injury evoked an increased relative activity of the acetylcholine esterase in the immature brain early after injury, without loss of cholinergic neurons in the basal forebrain. These changes may contribute to developmental impairments after immature traumatic brain injury.]]></dc:description>

<dc:title><![CDATA[Concomitant targeting of cyclooxygenase-2 and oxidant stress pathways for radioprotection of normal vascular tissue]]></dc:title>
<dc:source><![CDATA[European Journal of Cancer 8(2010), 211]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background: 
Radiotherapy of various cancers is closely associated with increased cardiovascular morbidity and mortality. Arachidonic acid metabolites are supposed to play a key role in radiation-induced vascular dysfunction, inflammation, and injury. This study was designed to evaluate the effects of novel selective cyclooxygenase-2 (COX-2) inhibitors on radiation-induced formation of arachidonic acid metabolites via cyclooxygenase-2 and oxidant stress pathways in endothelial cells.

Materials and methods: 
Acute effects (1 d, 3 d) of X-ray radiation at moderate doses (2 to 10 Gy) without or with presence of selective COX-2 inhibitors (cyclopentene/indole/indomethacin derivatives (2 each); 1 µM, 10 µM) in human arterial (HAEC) and microvascular (HDMEC) endothelial cells compared to sham-irradiated controls were assessed. Therefore, the following parameters were measured: COX-2 induction; secretion of cytokines tumor necrosis factor-α, interleukin-6, and monocyte chemoattractant protein-1; release of prostaglandins PGE2 and PGI2; release of isoprostanes 8-iso-PGE2 and 8-iso-PGF2α; and oxidative stress (lipid peroxides).

Results: 
Irradiation of endothelial cells without presence of COX-2 inhibitors resulted in a dose-dependent augmentation of all parameters studied. When endothelial cells were exposed to COX-2 inhibitors during and for 24 h post irradiation, indole derivatives showed highest potency to inhibit release of both prostaglandins and isoprostanes. Furthermore, when irradiated cells were treated with indole derivatives a significant decrease of lipid peroxide formation and cytokine secretion could be observed, which indicates a direct interaction with oxidant stress-pathways. By contrast, both cyclopentene and indomethacin derivatives majorily inhibited prostaglandin release, but showed only slight effects on formation of isoprostanes, lipid peroxides and cytokines. Model experiments using human low density lipoproteins oxidized by radiolytically generated oxygen radicals showed that indole derivatives differently interact with peroxidation of polyunsaturated fatty acids, than the cyclopentene/indomethacin derivatives, suggesting a physico-chemical rationale for observed anti-oxidant activity.

Conclusion: 
Indole-based selective COX-2 inhibitors substantially decreased radiation-induced formation of vasoactive isoprostanes
8-iso-PGE2 and 8-iso-PGF2α by endothelial cells. These findings may have particular importance in radiation-induced processes in which COX-2 is induced and oxidant stress occurs. The reduction of radiation-induced vascular dysfunction by antioxidative COX-2 inhibitors may widen the therapeutic window of cyclooxygenase-2 targeted treatment.]]></dc:description>

<dc:title><![CDATA[Concomitant targeting of cyclooxygenase-2 and oxidant stress pathways for radioprotection of normal vascular tissue]]></dc:title>
<dc:source><![CDATA[21st Meeting of the European Association for Cancer Research (EACR-21), 26.-29.06.2010, Oslo, Norway]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background: 
Radiotherapy of various cancers is closely associated with increased cardiovascular morbidity and mortality. Arachidonic acid metabolites are supposed to play a key role in radiation-induced vascular dysfunction, inflammation, and injury. This study was designed to evaluate the effects of novel selective cyclooxygenase-2 (COX-2) inhibitors on radiation-induced formation of arachidonic acid metabolites via cyclooxygenase-2 and oxidant stress pathways in endothelial cells.

Materials and methods: 
Acute effects (1 d, 3 d) of X-ray radiation at moderate doses (2 to 10 Gy) without or with presence of selective COX-2 inhibitors (cyclopentene/indole/indomethacin derivatives (2 each); 1 µM, 10 µM) in human arterial (HAEC) and microvascular (HDMEC) endothelial cells compared to sham-irradiated controls were assessed. Therefore, the following parameters were measured: COX-2 induction; secretion of cytokines tumor necrosis factor-α, interleukin-6, and monocyte chemoattractant protein-1; release of prostaglandins PGE2 and PGI2; release of isoprostanes 8-iso-PGE2 and 8-iso-PGF2α; and oxidative stress (lipid peroxides).

Results: 
Irradiation of endothelial cells without presence of COX-2 inhibitors resulted in a dose-dependent augmentation of all parameters studied. When endothelial cells were exposed to COX-2 inhibitors during and for 24 h post irradiation, indole derivatives showed highest potency to inhibit release of both prostaglandins and isoprostanes. Furthermore, when irradiated cells were treated with indole derivatives a significant decrease of lipid peroxide formation and cytokine secretion could be observed, which indicates a direct interaction with oxidant stress-pathways. By contrast, both cyclopentene and indomethacin derivatives majorily inhibited prostaglandin release, but showed only slight effects on formation of isoprostanes, lipid peroxides and cytokines. Model experiments using human low density lipoproteins oxidized by radiolytically generated oxygen radicals showed that indole derivatives differently interact with peroxidation of polyunsaturated fatty acids, than the cyclopentene/indomethacin derivatives, suggesting a physico-chemical rationale for observed anti-oxidant activity.

Conclusion: 
Indole-based selective COX-2 inhibitors substantially decreased radiation-induced formation of vasoactive isoprostanes
8-iso-PGE2 and 8-iso-PGF2α by endothelial cells. These findings may have particular importance in radiation-induced processes in which COX-2 is induced and oxidant stress occurs. The reduction of radiation-induced vascular dysfunction by antioxidative COX-2 inhibitors may widen the therapeutic window of cyclooxygenase-2 targeted treatment.]]></dc:description>

<dc:description><![CDATA[Microbes are widely distributed in nature also under harsh conditions (e.g., high salinity; low permeability; high and low temperatures). They can strongly influence the migration of hazardous actinides in the environment once they have been released. This is demonstrated by an increased interest in studies exploring the interaction processes involving actinides and bacteria during the last years. However, worldwide only little detailed information is available about the biodiversity and microbial influences on radionuclide migration under the conditions of a deep nuclear repository.
The presentation covers the broad topic of actinide interactions with bacteria. A short overview about the determination of the microbial diversity giving the dominant bacterial strains will be given. In more detail, the manifold interaction process of bacteria with actinides will be highlighted based on selected examples. 
With this presentation we want to point out the importance of actinide-microbe interactions for the disposal of nuclear waste.]]></dc:description>

<dc:date>2012</dc:date>
<dc:description><![CDATA[In this study UV-vis spectroscopy as well as RT and cryo time-resolved laser-induced fluorescence spectroscopy (TRLFS) were applied to reinvestigate the complexation of uranium(VI) by benzoic acid (BA). For the first time in the liquid phase the existence of a U(VI)-BA complex with a 1:2 stoichiometry could be proven. 
RT TRLFS measurements revealed a static as well as a dynamic ligand-initiated quench process in the U(VI)-BA system. At these conditions no luminescence emission resulting from complex formation was found. Consequently cryo TRLFS was applied to increase the maximum detect-able BA:U(VI) ratio. By this for the first time a lumines-cence spectrum of the 1:2 U(VI)-BA complex could be determined. This species is characterized by emission bands at 467, 485, 505, 526, and 550 nm which are blue-shifted compared to the ones of the uranyl ion. The luminescence lifetime of the 1:2 complex amounts to 9.21 ± 0.01 µs at -18°C compared to 150.4 ± 0.5 µs for uranyl.
Stability constants of both, the 1:1 and the 1:2 species, have been calculated to be log β110 = 2.66 ± 0.18 and log β120 = 4.48 ± 0.24, respectively. UV-vis spectroscopy combined with factor analysis yielded the molar absorption spectrum of the 1:2 U(VI)-BA species which is characterized by absorption bands at 406, 418, 432.5, 447, and 461 nm and a molar absorption coefficient of 22 L•mol-1•cm-1.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[The heart of the radiation source ELBE at the Forschungszentrum Dresden-Rossendorf (FZD) is a 40-MeV LINAC with an average current of 1 mA. Due to its superconducting technology, the time structure is different from conventional LINACs. Electron bunches as short as 2 ps with a 26 MHz repetition rate can be used in continuous operation (cw) mode. This is an ideal host for an intense positron source. After organizing SLOPOS-9 in Rossendorf, it was decided to add EPOS (ELBE Positron Source) to the existing experiments at ELBE. EPOS consists of two LINAC-based setups, Gamma-induced Positron Spectroscopy (GiPS) and Monoenergetic Positron Spectroscopy (MePS). The GiPS setup, where positrons are produced inside the whole sample volume by pair production using a pulsed gamma beam, is unique so far. Here, bulky samples such as coarse powders, dispersions, but also liquids or whole devices of non-destructive testing can be investigated by all positron techniques important for materials science (lifetime spectroscopy, age-momentum correlation, and coincidence Doppler broadening spectroscopy). The same techniques will be applied at the MePS setup, where slow, mono-energetic positrons will be generated by moderation to study near-surface layers. This system is still under construction. The EPOS system will be completed by two conventional setups, a continuous slow positron beam and a positron lifetime/ Doppler spectrometer, both operated by 22Na sources.]]></dc:description>

<dc:description><![CDATA[The multi-purpose particle interaction and transport code FLUKA is integral part of all radiation protection studies for the design and operation of the Large Hadron Collider (LHC) at CERN. It is one of the very few codes available for this type of calculations which is capable to calculate in one and the same simulation proton-proton and heavy ion collisions at LHC energies as well as the entire hadronic and electromagnetic particle cascade initiated by secondary particles in detectors and beam-line components from TeV energies down to energies of thermal neutrons. The present paper reviews these capabilities of FLUKA in giving details of relevant physics models along with examples of radiation protection studies for the LHC such as shielding studies for underground areas occupied by personnel during LHC operation and the simulation of induced radioactivity around beam loss points. Integral part of the FLUKA development is a careful benchmarking of specific models as well as the code performance in complex, real life applications which is demonstrated with examples of studies relevant to radiation protection at the LHC.]]></dc:description>

Der entstehende Komplex 2 [Re{NC(CH<SUB>3</SUB>)<SUB>2</SUB>(Me<SUB>2</SUB>PhP)}(DMSMe<SUB>2</SUB>)<SUB>2</SUB>] kristallisiert triklin in der Raumgruppe P1, a = 12,334(7), b = 12,412(7), c = 12,414(8) Å; alpha = 60,14(3)°, beta = 67,98(3)°, gamma = 80,63(6)°; Z = 2. Das Rhenium befindet sich in einer quadratisch-pyramidalen Anordnung der Donoratome. Die beiden meso-DMSMe<SUB>2</SUB>-Liganden sind in syn-endo-Stellung angeordnet. Die Rhenium-Stickstoff-Bindung ist mit 1,697(12) Å nur wenig länger als in Nitridokomplexen und vergleichbar mit anderen Re-N-C-Bindungsabständen. Der Angriff des Lösungsmittels am Nitridostickstoffatom wird in Aceton (2) und Methylethylketon unter Bildung von 3 beobachtet. Massenspektrometrisch wird darüberhinaus nachgewiesen, daß auch eine Reaktion des Nitridostickstoffatoms mit dem Kondensationsprodukt des Methylethylketons erfolgt unter Bildung von [ReN{C(CH<SUB>3</SUB>)(C<SUB>2</SUB>H<SUB>5</SUB>)CH<SUB>2</SUB>C(O)C<SUB>2</SUB>H<SUB>5</SUB>(Me<SUB>2</SUB>PhP)}(DMSMe<SUB>2</SUB>)<SUB>2</SUB>]) 4. ]]></dc:description>

<dc:description><![CDATA[The usefulness of <SUP>18</SUP>F-labelled carbohydrates, especially 2-deoxy-2-[<SUP>18</SUP>F]fluoro-D-glucose, to study pathophysiological processes in man non-invasively using positron-emission-tomography (PET) led to a widespread investigation of different <SUP>18</SUP>F-labelled sugars and sugar derivatives. In consideration of the short half-life of fluorine-18 (T<SUB>1/2</SUB>=110 min) synthetic strategies concerning precursor design, labelling conditions and deprotection of the intermediate compounds were developed to guarantee an efficient high radiochemical yield synthesis for diagnostic purposes. Besides some aspects of medical application of 2-deoxy-2-[<SUP>18</SUP>F]fluoro-D-glucose, a few synthetic strategies are described reflecting development work on promising <SUP>18</SUP>F-labelled sugars for diagnostic purposes during the last two decades]]></dc:description>

<dc:source><![CDATA[Inorg. Chim. Acta 304 (2000) 26-32]]></dc:source>

<dc:description><![CDATA[Two novel oxorhenium complexes containing the 2,6-dithiomethylpyridine ligand were synthesized according to the '3 + 1' and the '3 + 2' approaches, respectively, and characterized by classical methods of analysis. The [2,6-dithiomethylpyridinato][p-methoxybenzenethiolato]oxorhenium complex, 1, was produced by simultaneous action of equimolar quantities of 2,6-dithiomethylpyridine and p-methoxybenzenethiol on the precursor [(n-C<SUB>4</SUB>H<SUB>9</SUB>)<SUB>4</SUB>N][ReOCl<SUB>4</SUB>] in EtOH. As revealed by spectroscopic data as well as X-ray structure analysis, complex 1 adopts a distorted square pyramidal geometry around the metal with the SNS/S donors forming the basal plane and the oxygen occupying the apex of the pyramid. When the same tridentate ligand reacts with [(n-C<SUB>4</SUB>H<SUB>9</SUB>)<SUB>4</SUB>N][ReOCl<SUB>3</SUB>(PO)] (PO = o-diphenylphosphinophenolato) as a precursor, complex 2a, [2,6-dithiomethylpyridinato][o-diphenylphosphinophenolato]oxorhenium, is obtained. The latter is a six-coordinate rhenium species to which the distorted octahedral geometry is assigned, according to the analytical findings. In this case, the SNS/P donors occupy the equatorial plane and the two oxygen atoms the apices of the distorted octahedron positioned trans to each other.]]></dc:description>

<dc:title><![CDATA[Synthesis and Autoradiographic Evaluation of a Novel High-Affinity Tc-99m Ligand for the 5-HT<SUB>2A</SUB> Receptor]]></dc:title>
<dc:source><![CDATA[13. Intern. Symposium on Radiopharmaceutical Chemistry, Saint Louis, USA 1999]]></dc:source>
<dc:date>1999</dc:date>
<dc:description><![CDATA[The successful development of [<SUP>99m</SUP>Tc]TRODAT as ligand for the dopamine transporter has shown the feasibility to image specific transporters in the brain with radiotracers based on Tc-99m (1). In contrast to this achievement and despite the efforts many groups have devoted so far, the search for Tc-99m complexes with affinity to post-synaptic CNS receptors have not yet reached the same stage of development (2). As one of the consequences for the design of serotonin-5-HT<SUB>2A</SUB> receptor binding Tc-99m complexes an affinity of < 1nM is believed to be a prerequisite for further progress. Aiming at such a high affinity, we have pursued our design concept starting from ketanserin as lead structure for 5-HT<SUB>2A</SUB> receptor binding ligands (3, 4).
Here we report on the synthesis of a new high-affinity Tc-99m ligand that meets the requirement of picomolar affinity. The complex is evaluated in various receptor binding assays and by in vitro autoradiography.

<dc:title><![CDATA[Water repartitioning at the water lipid protein interface controls receptor activation in G-Protein coupled receptors]]></dc:title>
<dc:source><![CDATA[Annual Meeting of the German Biophysical Society, 03.-06.10.2010, Bochum, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[G-Protein coupled receptors (GPCRs) play a fundamental role in many physiological processes. High ligand specifity of rhodopsin-like GPCRs in contrast to the highly conserved and class defining D(E)RY motif undergoing a protonation upon receptor activation suggests a general local activation mechanism acting as an autonomous functional module.  
It has been shown that the D(E)RY motif positioned at the phase boundary acts as a pH-dependent switch which is governed by side chain partitioning between the aqueous and lipidic phase [1].
Here we have addressed the putative reverse effect, i.e. restructuring of the water lipid interface upon side chain protonation to elucidate the functional implication of water lipid protein interactions in the control of protein conformation. We have studied a TM3 derived transmembrane segment where a fluorescence reporter resides below the D(E)RY motif inside the helix. By fluorescence spectroscopy, FRET studies and FTIR-Fluorescence cross correlation experiments we show the pH dependent hydration site N-terminally of the D(E)RY motif. Thus the ionized D(E) side chain attracts water that dissolves the TM-sequence even beyond the two preceding hydrophobic residues. 
These results argue for a key role of the rearrangement of the water lipid protein microstructure upon GPCR activation as it effects not only the phase boundary but even  more hydrophobic environment inside the lipidic phase.

<dc:description><![CDATA[Since the identification of ongoing 26Al production in the universe, the reaction sequence 24Mg(p,γ )25Al(β+ν)25Mg(p,γ )26Al has been studied intensively. At temperatures where the radiative capture on 25Al (t1/2 = 7.2 s) becomes faster than the β+ decay, the production of 26Al can be reduced due to the depletion of 25Al. To determine the resonances relevant for the 25Al(p,γ )26Si bypass reaction, we measured the 28Si(p,t )26Si reaction with high-energy precision using the Grand Raiden spectrometer at the Research Center for Nuclear Physics, Osaka. Several new energy levels were found above the p threshold and for known states excitation energies were determined with smaller uncertainties. The calculated stellar rates of the bypass reaction agree well with previous results, suggesting that these rates are well established.]]></dc:description>

<dc:description><![CDATA[The preparation and characterisation of "3+1+1" technetium complexes of the gen-eral formula [Tc(SES)(RS)(PMe<SUB>2</SUB>Ph)] (SES = tridentate dithiol ligand, E = S, O, NMe; RSH = monothiol ligand) at the no carrier added level is described. The Tc(III) com-plexes are prepared in a one-step procedure starting from pertechnetate in yields of 85 - 95 % of radiochemical purity. A comparison of their chromatographic data with the fully characterised <SUP>99</SUP>Tc complexes indicate the identity of the investigated com-pounds. Stability studies show that the <SUP>99m</SUP>Tc complexes undergo some alteration in solution. They are oxidised to the 3+1 oxotechnetium(V) complexes and/or decom-pose in aqueous solution. In challenge experiments performed with glutathione, ex-change of the monothiolato ligand occurs in the same manner as known for the 3+1 complexes.]]></dc:description>

The rho meson is considered within a scenario of pure chiral restoration by dropping the chirally odd condensates. The interplay of mass shift and broadening of the spectral function is highlighted. We apply finite density QCD sum rules to mesons consisting of a heavy and a light quark (D, Ds and B) and investigate their sensitivity to the chiral condensate and consider the splitting of particle and antiparticle spectral functions with increasing density of the ambient nuclear matter. In order to gain a more direct dependence on the chiral condensate and other potential order parameters of chiral symmetry we present a series of Weinberg-Shuryak type sum rules for heavy-light systems at finite densities.

<dc:date>2010</dc:date>
<dc:description><![CDATA[Results on the experimental and numerical modelling of the melt flow typically observed in Vertical Gradient Freeze (VGF) crystal growth with a Travelling Magnetic Field (TMF) are presented. Particular attention is paid on the transition from a laminar to a time-dependent flow, which represents a crucial problem in VGF growth. Low-temperature model experiments at around 80°C were performed using a GaInSn melt in a resistance furnace with concentric, separately adjustable heating zones. The TMF was created by an external coil system, and the flow velocity was measured by means of the Ultrasonic Doppler Velocimetry (UDV). The melt flow was simulated numerically using a finite volume code based on the open source code library OpenFOAM. As a criterion for the stability of the flow the turbulent kinetic energy was calculated under the influence of the TMF and thermal buoyancy. The results obtained are compared to isothermal TMF flow modelling at ambient temperature. The stability limit of the melt flow is found to be significantly influenced by the mutual interaction of buoyant and TMF-driven flows. Both experimental and numerical results show the stabilizing effect of a natural, VGF-type buoyancy on the TMF-induced flow.]]></dc:description>

<dc:description><![CDATA[Recent experiments of the ANKE collaboration concerning the phi meson production in pA-reactions p (2.83 GeV) + C, Cu, Ag and Au are appropriate for the absorptive phi-N interaction within the trancparency ratio. With the aim of analyzing the amount of phi absorption we applied our well confirmed transport model of Boltzmann-Ühling-Uhlenbeck (BUU) type on this scenario. The results seem to point to an absorption cross section of 18 \pm 3 mb only when accounting for secundary phi production processes as well as isospin asymmetry and ANKE acceptance conditions.]]></dc:description>

<dc:source><![CDATA[Nucl. Phys. A 646 (1999) 367]]></dc:source>
<dc:date>1999</dc:date>
<dc:description><![CDATA[Directed sideward flow of light charged particles and intermediate mass fragments was measured in different symmetric reactions at bombarding energies from 90 to 800 AMeV. The flow parameter is found to increase with the charge of the detected fragment up to Z=3-4 and turns into saturation for heavier fragments. Guided by simple simulations of an anisotropic expanding thermal source, we show that the value at saturation can provide a good estimate of the flow angle, Θ<sub>flow,</sub> in the participant region. It is found that Θ<sub>flow,</sub> depends strongly on the impact parameter. The excitation function of Θ<sub>flow,</sub> reveals striking deviations from the ideal hydrodynamical scaling. The data exhibit a steep rise of Θ<sub>flow,</sub> to a maximum at around 250-400 AMeV, followed by a moderate decrease as the bombarding energy increases further.]]></dc:description>

<dc:title><![CDATA[Thermodynamical limits of diluted (magnetic) semiconductors]]></dc:title>
<dc:source><![CDATA[30th International Conference on the Physics of Semiconductors (ICPS 2010), 25.-30.07.2010, Seoul, Südkorea]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The incorporation of transition metal dopants in semiconductors above their solubility limit is the main challenge for the fabrication of diluted magnetic semiconductors. Dietl et al. have predicted the Curie temperature of different p-type conducting semiconductors alloyed with 5 at. % Mn [1]. This work motivated experimental efforts focused on the fabrication of highly diluted magnetic semiconductors. Unfortunately, such highly diluted magnetic semiconductors are metastable alloys and try to reach their thermodynamical equilibrium by the diffusion of the incorporated magnetic dopants leading to spinodal decomposition and secondary phase formation. There exist classical models which describe the kinetics of phase transitions and secondary phase formation for large clusters consisting of 100, 1000 or more atoms. However, electronic properties like carrier concentration strongly depend on the fraction of unclustered dopant atoms. Especially, in diluted magnetic semiconductors the formation of such clusters has to be prevented and growth techniques far from thermodynamical equilibrium are necessary.
Besides the LT-MBE process, the magnetic dopant implantation followed by pulsed laser annealing (PLA) appears to be a promising route for the fabrication of ferromagnetic semiconductors. The fast temperature quenching during PLA suppresses the diffusion of magnetic dopant atoms, i.e. diffusion via random hopping of these dopants is frozen and metastable diluted magnetic semiconductors are formed. 
In this contribution we present the results from combined random-walk simulations and heat-flow calculations to describe the initial cluster formation for different magnetic semiconductors being characterized by a large variation of diffusion coefficients of the magnetic dopants. Under the assumption that the de-clustering probability of neighbouring dopants is lower than the clustering probability, we can explain the successful fabrication of GaAs:Mn and the impossibility to fabricate diluted ferromagnetic Si:Mn with LT-MBE or Mn implantation followed by PLA. Especially, our modelling approach can be used to estimate first clustering events during the re-crystallization after PLA. Within this picture, we conclude that for the preparation of diluted ferromagnetic semiconductors the basic diffusion parameters and the room temperature solubility of the magnetic dopants are reasonable parameters to estimate the chance for a successful preparation of different kinds of diluted systems.

<dc:date>1999</dc:date>
<dc:description><![CDATA[The SWR1000 is a new innovative boiling water reactor concept, which is developed by Siemens AG. This concept is characterized in particular by passive safety systems (e.g. four emergency condensers, four building condensers, eight passive pressure pulse transmitters, six gravity-driven core flooding lines). In the framework of BWR Physics and Thermohydraulic Complementary Action (BWR-CA) to the EU BWR R&D Cluster emergency condenser tests were performed by Forschungszentrum Jülich at the NOKO test facility. In this paper post test calculations with ATHLET are presented, which aim at the determination of the removable power of the emergency condenser and its operation mode. The 1D thermal-hydraulic code ATHLET was extended by the module KONWAR for the calculation of the heat transfer coefficient during condensation in horizontal tubes. In addition, results of CFD-calculations using the code CFX-4 are presented, which investigate the natural convection during the heat up process at the secondary side of the NOKO test facility. ]]></dc:description>

<dc:description><![CDATA[Trace elements are more significant for provenance of archaeological metallic artifacts than the main components. For gold, the most promising elements are Platinum Group Elements (PGE), Sb, Hg, Pb, and, especially for alluvial (panned) gold, Sn and Pt. Several small fragments of ancient gold objects from some Bronze Age objects and Greek and Dacian (KOSON  type) coins were analyzed. To check if the Transylvanian gold was used, some fragments of nuggets from Transylvanian mines and alluvial gold were also studied. The measurements were performed by using the AGLAE accelerator of the Centre de Recherche et de Restauration des Musees de France. The samples were bombarded with a 3 MeV proton micro-beam (roughly 50 µm diameter). The employed   beam current was around 10 nA. We also used the micro-PIXE technique at the nuclear microprobe facility of the Forschungszentrum Dresden-Rossendorf. A 3 MeV proton beam was employed; the beam diameter was roughly 150 μm. The total accumulated charge was around 3 μC. 
As conclusions of the performed experiments, one can quote the following findings: 
- Sn was detected as a trace-element in all the KOSON without monogram coins; in one of them we could acquire spectra in several spots; in one of them a very high concentration of Sn was found but not in the surrounding areas, most probably a cassiterite grain; 
- No trace-elements were detected in the KOSON with monogram coins and the pseudo-Lysimach staters issued by the Greek colonies at the Black Sea coast; it was concluded that highly refined gold was used to manufacture these coins; the above findings led us to the idea that the two kind of KOSON coins were manufactured by using different gold sources 
- Sn was also found as trace element in a fragment taken from a Early Bronze Age bracelet from Tauteu, hoard (Transylvania) and in a fragment from the Vulchitrun-like disk (Late Bronze Age) found in Calarasi, Oltenia; we could conclude that alluvial gold was most likely used to manufacture these Bronze Age objects; 
- Te was found in several geological samples (e.g. in the ones from Rosia Montana), a fact that is of particular importance, since this element appears to be a characteristic of the Transylvanian gold minerals, but it is easily evaporated during the native gold melting, so, its presence in gold objects is very improbable; 
- A very interesting finding was the presence of Pd traces in one of the alluvial gold samples, the one coming from Mures river.]]></dc:description>

<dc:description><![CDATA[Recently, the new skutterudite superconductor PrPt<sub>4</sub>Ge<sub>12</sub> with the comparably high transition temperature of T<sub>c</sub> = 7.9 K was discovered [1]. First experiments gave evidence for strong coupling and hint at point-like nodes of the order parameter [2]. The Sommerfeld coefficient is rather low and indicates that PrPt<sub>4</sub>Ge<sub>12</sub> is not a heavy-fermion superconductor. Here, we present results of a de Haas-van Alphen (dHvA) study performed on a high-quality single crystal. Several dHvA frequencies could be resolved over a broad angular range. The small band-resolved effective masses (less than half the free-electron mass) confirm the non-heavy-fermion character of the electron system. To get insight into the nature of the mass renormalization, the experimental data are compared with state-of-the-art band-structure calculations]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Arsenic-doped ZnMgO films were fabricated on SiO<sub>2</sub> by the radio frequency magnetron sputtering technique at different substrate temperatures during growth. The yielded films were characterized by room temperature Hall measurement, x-ray diffraction, x-ray photoelectron spectroscopy, scanning electron microscopy, secondary ion mass spectroscopy, nuclear reaction analysis and low-temperature photoluminescence. As-doped samples grown at low substrate temperature (350 degrees C) were n-type conducting (n similar to 10<sup>18</sup> cm<sup>-3</sup>), with evidence showing that the hydrogen impurity was an important shallow donor associated with the observed n-type conduction. Conversion of n-type to p-type conduction being observed at the substrate temperature of similar to 400 degrees C was associated with the formation of the As<sub>Zn</sub>(V<sub>Zn</sub>)<sub>2</sub> shallow acceptor complex and the drastic reduction of the hydrogen content.]]></dc:description>

<dc:date>1998</dc:date>
<dc:description><![CDATA[We have investigated the complexation behavior of natural humic acids (HA) with model substances. Our synthetic HA model substance, prepared from glutamic acid and xylose, shows operational properties comparable to those of natural HA in terms of water solubility at different pH and in the type and number of its functional groups. We investigated its complexation behavior with the UO<sub>2</sub><sup>2+</sup> ion by time-resolved laser-induced fluorescence spectroscopy. For comparison, we used purified natural HA from Fluka and Aldrich. The experimental data were evaluated applying the metal ion charge neutralization model developed by Kim and Czerwinski. For our synthetic product, we determined a loading capacity of 23 ±  4 % and a complexation constant of log beta = 6.16 ±  0.22 (pH 3.90 ±  0.05; I: 0.1 M NaClO<sub>4</sub>).  The obtained values are comparable with experimental results determined for Fluka and Aldrich HA. These results lead to the conclusion that our synthetic product appropriately models the functionality of natural HA.]]></dc:description>

X-ray structure determination was performed for complexes 3 and 4. Complex 3 adopts the expected distorted trigonal bipyramidal geometry around the metal in a syn configuration, while complex 4, due to the aromatic character of the nitrogen of the SNS donor-atom set, exhibits a distorted square pyramidal geometry. The interaction of complexes 1 - 4 with glutathione (GSH) was studied by high performance liquid chromatography (HPLC), revealing the rapid formation of the respective daughter complexes 5 - 8, wherein the L coligand has been substituted by GS. The daughter complexes 5 - 8 have been characterized by ES-MS and a battery of NMR measurements involving HETCOR, COSY and NOESY procedures. Kinetic aspects of the interaction of complexes 1 ¾ 3 with GSH have been studied by isothermal titration microcalorimetry providing direct measurements of the interaction rate constants as well as the total enthalpy change. The reaction of complex 1 is characterized by the slowest and that of complex 2 by the fastest rate. This is in agreement with previously reported trends for analogous <SUP>99m</SUP>Tc complexes.]]></dc:description>

<dc:date>2000</dc:date>
<dc:description><![CDATA[The irradiation-induced microstructural changes in surveillance materials of the VVER 
440-type weld metal Sv-10KhMFT were investigated by small angle neutron scattering 
(SANS) and anomalous small angle X-ray scattering (SAXS). Due to the high fluence 
a strong effect was found in the SANS experiment. No significant effect of the irradiationis detected by SAXS. The reason of this discrepancy is the different 
scattering contrast of irradiation-induced defects for neutron and X-rays. An analysis 
of the small angle X-ray scattering shows that the scattering intensity is mainly caused by vanadium-containing precipitates and grain boundaries. Both types of scattering defects are hardly changed by irradiation. Neutron irradiation rather produces additional scattering defects of few nanometers in size. Assuming these defects are clusters containing copper and other foreign atoms with a composition according to results of atom probe field ion microscopy investigations, both the high SANS and the low SAXS effect can be explained. ]]></dc:description>

New surface phases were shown to be incorporated into the surface: sodium titanates Na2TiO3 (in the as-implanted state) and Na2Ti6O13 (after 20 min heating at 700 °C in air). A variable level of the surface porosity and roughness was observed depending on the applied ion dose and energy.

<dc:date>2001</dc:date>
<dc:description><![CDATA[We present the results of a systematic investigation of neutron-irradiated and thermally-annealed model alloys using positron annihilation spectroscopy (PAS), including both lifetime and Doppler broadening techniques. The objective of this work is to use PAS to provide information on the irradiation-induced microstructural features that are thought to cause embrittlement in pressure-vessel steels. Such information could complement the results obtained by other techniques, especially small-angle neutron scattering (SANS) and atomic probe field ion microscopy (APFIM). We examined a series of model Fe-based alloys, in which the Cu, P and Ni concentration were systematically varied. These alloys were examined in the as-fabricated state, after irradiation to 1 x 10 19 nxcm-2, and to 8 x 10 19 nxcm-2, and after successive post-irradiation 30-minute isochronal anneals at temperatures ranging from 200 to 600 °C. In each case, we measured the positron annihilation lifetime distribution, the Doppler broadening (S-parameter), and the 15 N Rockwell hardness for the samples. ]]></dc:description>

<dc:description><![CDATA[
Uranium(VI) complex formation at vegetative cells and spores of Bacillus cereus and Bacillus sphaericus was studied using uranium LII-edge and LIII-edge extended x-ray absorption fine structure (EXAFS) spectroscopy. A comparison of the measured equatorial U-O distances and other EXAFS structural parameters of uranyl complexes formed at the Bacillus strains with those of the uranyl structure family indicates that the uranium is predominantly bound as uranyl phosphate.

<dc:source><![CDATA[The 18th International Conference on Ion Implantation Technology (IIT 2010), 06.-11.06.2010, Kyoto, Japan]]></dc:source>

<dc:description><![CDATA[According to the subsequently continued shrinking of semiconductor device dimensions the fabrication of ultra shallow pn-junctions is the essential requirement for modern CMOS technology. Therefore the importance of measurement techniques for dopant depth profiles is rising and the demands in resolution and accuracy are increasing. The established methods like SIMS and spreading resistance profiling become less suitable for these applications because of their disadvantages at measurements near the silicon surface.
Stepwise Oxidation Profiling was applied to boron doped p+ layers as a new measurement technique for ultra shallow doped layers. Single crystalline n-type silicon (110 Ohmcm) with <100>- orientation was used as base material. One sample type was implanted with boron at an ion energy of 1 keV and an implantation fluence of 3x1014 cm<sup>-2</sup>. After implantation the samples were annealed by rapid thermal annealing (RTA) at 1000 °C and 10 s annealing time. On the other sample type boron was deposited by e-beam evaporation. Following, a 400 keV Si pre-implant was done to avoid transient enhanced diffusion and then a flash lamp diffusion (FLD) was carried out with 600 °C preheating and a 1300 °C Xe flash of about 3 ms duration. The two sample types were fabricated as planar van der Pauw (VDP) test structures.
Compared to the Continuous Anodic Oxidation Technique (CAOT) developed by S. Prussin the measurement procedure of SWOP is similar and the dopant depth profiles are measured by altering between an electrical VDP measurement of the sheet resistance and the electrochemical growth of thin anodic SiO2 layers (in steps of 1 nm and below). The SWOP measurement can be done in one apparatus without removing the sample for anodic oxidation or electrical VDP measurement. The values of the active boron concentration are calculated using the hole mobility values based on the Thurber expression.]]></dc:description>

<dc:source><![CDATA[5th Forum on New Materials (in the framework of 12th International Conference on Modern Materials and Technologies - CIMTEC 2010), 13.-18.06.2010, Montecatini Terme, Italien]]></dc:source>

<dc:description><![CDATA[The synthesis of transparent conductive oxides (TCO) with high transmittance in the near infrared (IR) spectral range is a key requirement for increasing the power conversion efficiency in thin film solar cells. As the absorption at energies close to the Si band gap (1.1 eV) is caused by the free electron plasma it is necessary to maximize their mobility at moderate densities (~5x10<sup>20</sup> cm<sup>-3</sup>) in order to simultaneously reach low resistivities of ~2x10<sup>-4</sup> Ohm*cm and improve the IR transmittance.
Therefore a reactive magnetron sputtering method using metallic Zn/Al alloy targets was developed to achieve high carrier mobilities (~45 cm<sup>2</sup>/Vs) in ZnO:Al thin films. The influence of growth temperature, oxygen partial pressure and target Al concentration on the electrical film properties has been investigated systematically by Hall effect measurements.
Additionally XRD, X-TEM, AFM, ERDA, RBS and spectroscopic ellipsometry were employed to reveal film structure, composition and optical properties. The experimentally observed limit of mobility in polycrystalline ZnO:Al is discussed in terms of ionized impurity scattering and clustering as well as grain boundary limited transport.]]></dc:description>

<dc:source><![CDATA[Nanoscale Research Letters 6(2011), 26]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[We describe a two-step synthesis of pure multiwall MoS<SUB>2</SUB> nanotubes with a high degree of homogeneity in size. The Mo<SUB>6</SUB>S<SUB>4</SUB>I<SUB>6</SUB> nanowires grown directly from elements under temperature gradient conditions in hedgehog-like assemblies were used as precursor material. Transformation in argon-H<SUB>2</SUB>S/H<SUB>2</SUB> mixture leads to the MoS<SUB>2</SUB> nanotubes still grouped in hedgehog-like morphology. The described method enables a large scale production of MoS<SUB>2</SUB> nanotubes and their size control. X-ray diffraction, optical absorption and Raman spectroscopy, scanning electron microscopy with wave dispersive analysis, and transmission electron microscopy were used to characterize the starting Mo<SUB>6</SUB>S<SUB>4</SUB>I<SUB>6</SUB> nanowires and the MoS<SUB>2</SUB> nanotubes. The unit cell parameters of the Mo<SUB>6</SUB>S<SUB>4</SUB>I<SUB>6</SUB> phase are proposed. Blue shift in optical absorbance and metallic behaviour of MoS<SUB>2</SUB> nanotubes in two-probe measurement are explained by a high defect concentration.]]></dc:description>

<dc:source><![CDATA[Applied Radiation and Isotopes 51 (1999) 37-41]]></dc:source>
<dc:date>1999</dc:date>
<dc:description><![CDATA[Alkaline hydrolysis of 1,3,4,6-tetraacetyl-2-(<SUP>18</SUP>F]fluoro-deoxy-D-glucose in the course of 2-[<SUP>18</SUP>F]fluoro-deoxy-D-glucose (<SUP>18</SUP>FDG) synthesis offers special advantages over acidic hydrolytic procedures, because the reaction time is short and thermal requirements are very mild. In view of the possible epimerization of  2-[<SUP>18</SUP>F]fluoro-deoxy-D-glucose a multi-centre study has been performed to check the safety of this method for routine production of <SUP>18</SUP>FDG in view of the quality standards set by the European Pharmacopoeia. The study revealed that in using 0.33 M NaOH for the hydrolysis, a limitation of the reaction temperature to 40°C and a restriction of the reaction time to 5 min represent reaction conditions, which reliably limit the epimerization of <SUP>18</SUP>FDG to <SUP>18</SUP>FDM to 0.5%. Regarding the quality requirements on FDG as set forth by pharmacopoeial standards, alkaline hydrolysis of the intermediate in routine <SUP>18</SUP>FDG production is a safe and efficient reaction pathway, which furthermore obviates the requirement to check for other 2-substituted deoxy-D-glucose derivatives.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[We studied the angular dependence of the ferromagnetic resonance (FMR) spectra of (0001)ZnO single crystals implanted with Ni and Fe ions and compared the results to the data obtained by other experimental techniques, especially, x-ray diffraction (XRD) and superconducting quantum interference device magnetometry. The FMR revealed the formation of metal nanocrystals (NCs) embedded in the ZnO lattice in an oriented way. Whereas in the case of Ni, the conclusions drawn from the FMR studies corroborated the XRD and magnetometry results with respect to the alignment of the NCs in the host lattice, in the case of the Fe NCs, the FMR clearly shows that the hard magnetization axis (which is < 111 > in bcc Fe) is oriented perpendicular to the sample surface (parallel to the [0001]ZnO axis), at variance with the former XRD observations.]]></dc:description>

<dc:title><![CDATA[In Vivo Binding of [18F]NS10743 on α7 Nicotinic Acetylcholine Receptors (α7-nAChR) in Pig Brain]]></dc:title>
<dc:source><![CDATA[23rd Annual Congress of the European Association of Nuclear Medicine (EANM), 09.-13.10.2010, Wien, Österreich]]></dc:source>

<dc:description><![CDATA[Aim: Alterations of α7-nAChR have been observed in schizophrenia, brain trauma and neurodegenerative diseases. For PET imaging of α7 nAChR [18F]NS10743 has been successfully developed and evaluated in mice by tissue distribution and specificity studies. Here we report on baseline and blocking PET studies with [18F]NS10743 in pig brain. 

Materials and Methods: Dynamic PET scanning (2h) was performed in anesthetized female piglets (13-15 kg), intravenously injected with ~ 330 MBq [18F]NS10743 (specific activity >150 GBq/µmol). Three animals additionally received 5 mg/kg of the α7 nAChR antagonist NS6740. Plasma samples were taken and metabolite-corrected input functions were estimated. Individual regions of interest were defined using an MRI-based template of pig brain.  SUV, distribution volume (VT= K1/k2) and binding potential (BPND = (VT region - VT reference)/VT reference) were estimated. 

Results: [18F]NS10743 readily passed the blood-brain barrier and the uptake of radioactivity peaked with SUV = 2.23±0.71 at 8-10 min in the baseline scan while in NS6740-blocking studies the radioactivity levels peaked significantly earlier (SUV = 3.02 ± 1.28 at 6 min)  and decreased faster. At the end of study (between 90 and 120 min pi) SUV was significantly decreased by NS6740 in all investigated brain regions except olfactory bulb, which was chosen as reference region for calculation of BPND. At baseline, a mean VT value of 6.07±1.54 was estimated with the highest radiotracer accumulation in temporal, parietal, and occipital lobe, thalamus, striatum, and middle cortex (VT = 7.27±1.95  7.10±1.58). Intermediate binding was observed in hippocampus, colliculi, midbrain, frontal lobe, and ventral cortex (VT = 6.76±1.71  6.09±1.05), and lowest values were assessed in the cerebellum, pons, and olfactory bulb (VT = 5.71±1.18  4.11±0.96). Baseline BPND values for high (temporal lobe), median (hippocampus) and low specific binding (cerebellum) were  0.76±0.07, 0.54±0.08, and 0.39±0.08, respectively. NS6740 significantly reduced the binding potential BPND in regions with high [18F]NS10743 binding (temporal lobe: -29 %, p = 0.01; midbrain: -35 %, p = 0.02) while the decrease in regions with low binding was not significant (cerebellum: -16 %, p = 0.2). 

Conclusion: The data provide clear evidence of in vivo binding of [18F]NS10743 at α7 nAChR. However, with regard to the low density of α7 nAChR expression in the brain further modifications of the NS10743 core structure are needed to increase the target affinity of the tracer compound.]]></dc:description>

<dc:source><![CDATA[21st International Conference on the Application of Accelerators in Research and Industry (CAARI 2010), 08.-13.08.2010, Dallas/Fortworth, Texas, USA]]></dc:source>

<dc:description><![CDATA[Lasers can process materials at spatiotemporal µm and ps scales. Here it will be shown that swift heavy ions can be used for materials processing at even shorter length and time scales.  Swift-heavy-ion-induced deformation of spherical Au and Ge nanoclusters (NCs) embedded in SiO2 was studied experimentally and theoretically. Ge NC shaping is size dependent under  irradiation with 38 MeV iodine ions and with 89 and 185 MeV gold ions. Large NCs dont deform, smaller ones become discus-shaped, and very small ones show Ge loss at their equator. Small Au NCs deform into rods and wires, and, rather exotic, at critical NC size Au wires are squeezed out of the poles of the Au spheres.
Modeling and atomistic computer simulations identified the main driving forces: (i) The materials dependent electronic stopping power, (ii) the volume change upon melting, (iii) the asymmetric hydrodynamic flow due to stress field hysteresis, as well as (iv) far-from-equilibrium steady-state solubilities and strongly anisotropic diffusion. The latter one leads to Ostwald ripening of deformed NCs. The NC size distributions, shapes and anisotropies can be tailored by appropriate tuning of the driving forces. Our model describes the ion-induced shape evolution of different elements for different ion species, energies and fluences even quantitatively, where only one fit parameter describes all experiments. It is based on classical thermodynamics and hydrodynamics only. An even stronger proof is the shape change of nanospheres of critical size under swift heavy ion irradiation. For such particles, exclusively central ion impacts induce shaping, where Au is squeezed out of the poles. Using an unimodal size distributions and changing the ion impact angle during irradiation, tailoring of very exotic nanoparticle shapes become feasible.]]></dc:description>

<dc:description><![CDATA[The self-organisation of periodic pattern on (001)Ge by bombardment with different heavy ion species (Bi+, Bi++, Bi2+, Bi3+, Bi3++) obtained from a liquid metal ion source in a mass separating 30 kV FIB system was studied. Aspect ratios exceeding values reported so far for elemental semiconductors substantially were found after cluster irradiation. An excellent regular self-ordering of dot (40 nm in height, interdistance of ~50 nm) and ripple pattern was achieved. Despite of high ion fluence, Raman measurements prove a crystalline surface layer. This result deviates drastically from monomer irradiation, where similar to former ion irradiation of Ge a spongy amorphous surface layer is formed. For the transition from the usual behaviour to the unexpected pronounced pattern formation a threshold of the energy density deposited by the collision cascade was identified: If the deposited energy density exceeds the melting threshold, dot or ripple pattern appear. In our model we assume that the ion-impact-induced deposition of energy per volume (estimated by SRIM) must exceed the energy needed for melting. Thus, Bi segregation during re-solidification of the melted pool and the 5% volume difference between molten and solid Ge can cause the observed Bi separation and Ge patterning, respectively. A consistent, qualitative model will be discussed.]]></dc:description>

<dc:description><![CDATA[The self-organisation of periodic pattern on (001)Ge by bombardment with different heavy ion species (Bi+, Bi++, Bi2+, Bi3+, Bi3++) obtained from a liquid metal ion source in a mass separating 30 kV FIB system was studied. Aspect ratios exceeding values reported so far for elemental semiconductors substantially were found after cluster irradiation. An excellent regular self-ordering of dot (40 nm in height, interdistance of ~50 nm) and ripple pattern was achieved. Despite of high ion fluence, Raman measurements prove a crystalline surface layer. This result deviates drastically from monomer irradiation, where similar to former ion irradiation of Ge a spongy amorphous surface layer is formed. For the transition from the usual behaviour to the unexpected pronounced pattern formation a threshold of the energy density deposited by the collision cascade was identified: If the deposited energy density exceeds the melting threshold, dot or ripple pattern appear. In our model we assume that the ion-impact-induced deposition of energy per volume (estimated by SRIM) must exceed the energy needed for melting. Thus, Bi segregation during re-solidification of the melted pool and the 5% volume difference between molten and solid Ge can cause the observed Bi separation and Ge patterning, respectively. A consistent, qualitative model will be discussed.]]></dc:description>

<dc:description><![CDATA[ZrO2 layers stabilized with 9mol% Y2O3 of 35-100 nmthickness were deposited by sputtering on 200 nm thick Fe layers on Si/SiO2. Ion beam mixing induced by 300 keV Kr ions and 1.5 MeV Br ions bombardement was studied at temperatures ranging from 100 to 300 K. Samples were analysed by means of RBS, GXRD, and SEM techniques. RBS analysis revealed important atomic transport across the ZrO2/Fe interface. The amount of intermixed atoms increases with increasing ion dose. Ion beam mixing was observed at low temperaturesw. Upon 300 keV Kr-ion bombardment the tetragonal structure of as-deposited ZrO2(Y2O3) layers was transformed into the cubic one. High energy ion bombardment produces only transformations of the crystalline structure without any visible atomic transport and the formation of the rare FeO-wuestite phase. Kr blistering was observed from samples implanted with 300 keV Kr ions to fluences exceeding 1e16 at/cm2 at 100 K and 5e16 at/cm2 at RT.]]></dc:description>

<dc:source><![CDATA[FZD Doktorandenseminar, 22.-24.09.2010, Krögis (Meissen), Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[This thesis is located at the Institute of Radiochemistry, FZD Research Site Leipzig for Interdisciplinary Isotope Research, Reactive Transport Division (FWRT). The main focus of this division is the investigation of transport processes in geosystems by means of radiotracer applications. The main topic of the thesis is the visualization of transport processes in geologic material by means of the in-house development of the GeoPET-method. This work is conducted as part of the scientific joint venture: Dynamik abgesoffener oder gefluteter Salzbergwerke und ihres Deckgebirgsstockwerks (Dynamic of drowned or flooded salt mines and their overburden), coordinated by the Bundesanstalt für Geowissenschaften und Rohstoffe (BGR).

Since the late 19. century drowned salt mines cause severe mining damages in the city of Stassfurt (Saxony-Anhalt). Sink hole depressions and subsidence of the surface below the groundwater table destroyed large parts of the down town. The general causation was lack of experience with salt mines and mining in gypsum karst in the 19. century.  The causation in detail why and how exactly salt rock has washed out is more complicated to identify, as streaming mechanisms at the small scale level are partly still unclear; the general fluid dynamics at small scales is partly unknown.

To reveal these processes and mechanisms the behaviour of salt brines at the millimetre scale in drilling cores of the different geological units of the salt rock and its surrounding is examined by three-dimensional visualization of the distribution of radioactive labelled water measured with PET. Mechanisms at millimetre scale control mechanisms at the kilometre scale and are of utmost importance for the principal understanding of fluid dynamics. In the laboratory you can have a look into the rock. In the field this is not possible this way.

Combining PET data with high resolution CT-scans of the samples (conducted by the cooperation partners JGU Mainz and BAM Berlin) allows an alignment of processes of the fluid flow and its associated hydraulic pathway structures. This matching is important for understanding and for generalized conclusion about ongoing processes and is a necessary preparatory work for computer modelling.

Lattice-Boltzmann-simulations of velocity fields and streaming patterns based on CT-data are compared with PET-data derived from the same samples. This comparison of the flow patterns is done by means of geostatistic methods that allows scale independant spatial correlation of the patterns and therefore provide scale indpendant parameters like correlation lengths that are a necessity for upscaling.

Short term objective is the improvement and validation of parameters and fluid flow concepts derived from small scale simulations. Long term objective is the improvement of upscaling of parameters and concepts to the field scale and a better understanding and prediction of mining damages and groundwater behaviour.]]></dc:description>

<dc:date>1998</dc:date>
<dc:description><![CDATA[For measuring sputtering yields with MeV heavy ions only low current densities can be used in order to avoid excessive target heating. Consequently self-cleaning of the target surface during the irradiation cannot be achieved and a contamination free surface has to be maintained by means of UHV conditions. A UHV-setup including a differential pumping system has been designed and operated at a vacuum of 10<sup>-10</sup> mbar during experiments. Sputtered particles were collected on Si catchers and subsequently measured by two different surface analysis methods: Total Reflection X-Ray Fluorescence (TXRF), and Heavy Ion Rutherford Backscattering Spectrometry (HI-RBS). In-situ surface cleaning by 8 keV Xe ions as well as online monitoring by ERDA were found to be essential. With sufficient precautions on the surface conditions reproducible sputtering yields were obtained. First  measurements for 230 MeV Au ions on Au, Zr, and Ti targets are presented.]]></dc:description>

<dc:description><![CDATA[

Using the FOPI detector at GSI Darmstadt, excitation functions of collective flow components were measured for
the Au+Au system, in the reaction plane and out of this plane, at seven incident energies ranging from 100A MeV
to 800A MeV. The threshold energies, corresponding to the onset of sideward-flow (balance energy) and
squeeze-out effect (transition energy), are extracted from extrapolations of these excitation functions toward
lower beam energies for charged products with Z>= 2. The transition energy is found to be larger than the balance
energy. The impact parameter dependence of both balance and transition energies, when extrapolated to central
collisions, suggests comparable although slightly higher values than the threshold energy for the radial flow. The
relevant parameter seems to be the energy deposited into the system in order to overcome the attractive nuclear
forces.]]></dc:description>

<dc:source><![CDATA[Neuropathology and Applied Neurobiology 36(2010), 225-236]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Aims: Traumatic brain injury (TBI) is one of the leading causes of death and disability in children. Adult animal models of TBI showed cholinergic alterations. However, there is no comparable data on immature animals. Therefore, this study investigates cholinergic markers in a large animal model of juvenile TBI. Methods: Twenty-seven female newborn piglets were subjected to lateral fluid percussion (FP) injury and compared with 12 untreated animals. After 6 h, animals were sacrificed and the brains removed.The hemispheres ipsilateral to FP-TBI from seven piglets and corresponding hemispheres from six control animals were used for autoradiography. Receptor density was determined with [3H]epibatidine (nicotinic acetylcholine receptors) or [3H]QNB (muscarinic acetylcholine receptors). The density of the vesicular acetylcholine transporter (vAChT) was assessed with (-)-[3H]vesamicol. Cerebral blood flow was measured by coloured microsphere method. Results: Cerebral blood flow and brain oxygen delivery were transiently reduced early after FP-TBI (P < 0.05). TBI caused reductions of muscarinic acetylcholine receptor density (fmol/mg) in the basal forebrain (sham: 10797  1339, TBI: 8791  1031), while nicotinic acetylcholine receptor remained stable. Significant increases in vAChT density (fmol/mg) were observed in the basal forebrain (sham: 2347  171, TBI: 2884  544), putamen (sham: 2276  181, TBI: 2961  386), cortex (sham: 1928  262, TBI: 2377  294), thalamic areas (sham: 2133  272, TBI: 2659  413), hippocampus (sham: 2712  145, TBI: 3391  501) and hypothalamus (sham: 2659  139, TBI: 3084  304). Conclusions: Cholinergic markers are altered after mildto- moderate TBI in the immature brain.Whereas the ACh receptors are stable in almost any brain region after TBI, vAChT expression increases after trauma at the employed severity of this specific trauma model.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Here we report on direct transport measurements on a G-quadruplex covalently wired between two gold electrodes realized by the mechanically controllable break junction technique. We found that the G-quadruplex shows a rather high conductance. Interestingly, when the distance of both electrodes was reversibly varied over a several nm-span this conductance behavior persists reproducibly. These hitherto unprecedented properties make G-quadruplexes interesting candidates for nanoelectronic applications where varied distances between electrodes need bridging without loss of conductance.]]></dc:description>

<dc:description><![CDATA[In ion beam analysis the decrease of the measuring signal with a number of incident ions, due to a destruction of the surface layer being analysed, depends critically
on the lateral intensity distribution in the analysing ion beam. For the assumption of destruction in one step, the decrease was calculated and the obtained analytical
formulae was fitted to the decrease as measured in ERDA and PIXE analyses. This allows to obtain values for the destruction cross sections for the ions and the
samples in the analysis, as well as information about the lateral intensity distribution in the analysing ion beam.]]></dc:description>

<dc:description><![CDATA[FTIR spectroscopy has become an important non-destructive tool in gathering structural information of biological macromolecules at atomic resolution and under functional conditions. Modern instrumentation allows recording high resolution IR spectra of biomolecules in liquids, thin films, and adsorbed monolayers without chemical modification. The time-course of structural changes of biomolecules can be followed easily down to ~20 ms time resolution with rapidly scanning interferometers.  If such reactions are highly reproducible, molecular mechanisms can be studied at a time resolution down to ns by step scan interferometers. Despite the advanced user-friendliness in operating modern FTIR spectrometers, the use of the adequate detector type, the correct adjustment of the signal to noise ratio, the setting of optical and electronic filters to physically restrict the band width and the corresponding choice of the interferometer scanning speed are crucial parameters in the hand of the user. Their prudential use is essential for gaining high quality spectra by proper signal averaging procedures in static as well as time-resolved experiments and for avoiding spectral artefacts inherent to improper sampling of both the optical path and the intensity of the IR interferogram.]]></dc:description>

<dc:description><![CDATA[The high-pressure induced structural phase transitions and pressure induced elastic and anharmonic behavior of boron compounds viz. BN, BP, and BAs have been investigated using an inter-ionic potential approach based on charge transfer effect. These compounds go to NaCl phase (B1) under pressure from zinc blende phase (B3). The variations of second-order elastic constants and their combinations follow a systematic trend with pressure, identical to that observed in other compounds of zinc blende structure family. Shear stiffness constants decrease with increasing pressure up to phase transition pressure. The bulk moduli of these compounds are in reasonably good agreement with other theoretical and experimental data. The values of phase transition pressure of these compounds obtained by using the present approach are also in good agreement with those predicted by using the pseudo potential approach. The present approach has also succeeded in predicting the Born and relative st!
 ability criterion for stable zinc blende phase of these compounds. We also present a set of third-order elastic constants and pressure derivatives of second-order elastic constants for boron compounds.]]></dc:description>

<dc:date>2000</dc:date>
<dc:description><![CDATA[The phase formation and annealing behaviour are reported after nitrogen PIII in two austenitic stainless steels, DIN 1.4541
(X6CrNiTi18.10) and DIN 1.4571 (X6CrNiMoTi17.12.2), differing only in the Mo content. The treatment parameter were
pulses of 10 s and 40 kV for a nitrogen dose of 4×1018 cm-2 at a temperature of 380°C. In 1.4541, without Mo, the modified
layer is limited to 1.5 m while the 2 wt.% Mo-containing 1.4571 exhibits a layer thickness of 15 m. No difference in the
hardness (corrected for the layer thickness) and the wear behaviour was observed. Using X-ray diffraction (XRD) a lattice
expansion between 5 and 11%, was observed, not correlated with the nitrogen content (as determined by glow discharge
optical spectroscopy ¯¯ GDOS). After annealing at 400 and 425°C for different times, the lattice constant is slightly reduced,
albeit no phase transformation was observed in 1.4571. In 1.4541 at a temperature of 425°C a strong reduction of the lattice
expansion, coupled with an inward diffusion of the nitrogen was observed. No mechanism explaining this behaviour is available
at the moment.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[In order to shed more light on the role of magnetic gradient forces and Lorentz forces on the deposition pattern found recently at copper electrodes, experiments and numerical simulations have been performed in a generic geometry that consists of a single small cylindrical permanent magnet which is placed behind the cathode. The cylinder axis coincides with the magnetization direction and points normal to the electrode surface. The electrode is oriented vertically which allows a separate discussion of the influence of both forces.

Experiments and numerical simulations are found to give very good agreement with respect to the deposition pattern. Our analysis clearly shows that the major influence is due to the action of the magnetic gradient force. Numerical simulations prove that the separate action of the Lorentz force does not reproduce the deposition structure. A detailed analytical discussion of the motion forced by the different magnetic forces in superposition with natural convection is given.]]></dc:description>

<dc:title><![CDATA[Novel <SUP>99m</SUP>Tc '4 + 1' peptide conjugates: Tuning the biodistribution by variation of coligands]]></dc:title>

<dc:description><![CDATA[A sophisticated coligand strategy is presented for peptide-derived radioconjugates based on <SUP>99m</SUP>Tc '4 + 1' mixed-ligand complexes. The new pharmacologically active coligands are assessed for <SUP>99m</SUP>Tc-labeling of the RGD-peptide cyclo(Arg-Gly-Asp-D-Tyr-Lys) which is an established vehicle to target a<SUB>v</SUB>ß<SUB>3</SUB> integrins playing a crucial part in tumor pathogenesis.
Complexes of the general formula [<SUP>99m</SUP>Tc(NS<SUB>3</SUB>R)X] were synthesized and evaluated, in which Tc(III) is coordinated by NS<SUB>3</SUB>R, a derivative of the tetradentate chelator 2,2´,2´´-nitrilotriethanethiol (NS<SUB>3</SUB>), and by X, a monodentate binding isocyanide bearing the biomolecule. The novel tetradentate chelators (NS<SUB>3</SUB>R = NS<SUB>3</SUB>crown, NS<SUB>3</SUB>en, NS<SUB>3</SUB>(COOH)<SUB>3</SUB>) constitute NS<SUB>3</SUB> with a crown ether, an amine or a tricarboxylic acid as pharmacological modifiers. The isocyanides (X = L2-RGD, L2-Lys) contained the linker isocyanobutanoic acid (L2) coupled to N<SUP>6</SUP>-Lys of the RGD-peptide and additionally to a single Lys.
The lipophilicity (distribution coefficient log D<SUB>O/W</SUB>, pH = 7.4) of the RGD-containing radiotracers decreased in the order of the coligands NS<SUB>3</SUB>crown (-1.7 +/- 0.1), NS<SUB>3</SUB>en (-2.7 +/- 0.1) and NS<SUB>3</SUB>(COOH)<SUB>3</SUB> (-3.3 +/- 0.1). In the same order of the coligands, the biodistribution of the series [<SUP>99m</SUP>Tc(NS<SUB>3</SUB>R)(L2-RGD)] in normal rats showed a decrease of hepatobiliary and an increase of urinary excretion.
The ratio of specifically to unspecifically uptaken activity (sum of surface bound and internalized activity) in a<SUB>v</SUB>ß<SUB>3</SUB> integrin-expressing M21 cells was in the range of approximately 4-5 and comparable for all [<SUP>99m</SUP>Tc(NS<SUB>3</SUB>R)(L2-RGD)] tracers. The biodistribution of [<SUP>99m</SUP>Tc(NS<SUB>3</SUB>en)(L2-RGD)] in v/v mice bearing M21 and M21L (control) tumor xenografts exhibited a specific tumor uptake with a low target-background ratio.
The metabolic stability of the [<SUP>99m</SUP>Tc(NS<SUB>3</SUB>R)(L2-RGD)] tracers in normal rats was high, since 75-87% of the radioactivity in the plasma extract was assigned to the injected radiotracers 60 min after intravenous
application in a rat. The hypothetical metabolites [<SUP>99m</SUP>Tc(NS<SUB>3</SUB>R)(L2-Lys)] were not found.
These results demonstrate a considerable improvement of in vivo properties of <SUP>99m</SUP>Tc '4 + 1' peptide conjugates and open up the possibility of applying the labeling approach for further radiodiagnostic peptides.]]></dc:description>

<dc:description><![CDATA[Increasing the power conversion efficiency of modern thin film solar cells based on absorbers like silicon (Eg=1.11 eV), CuIn_xGa_(1-x)Se_2 (Eg=1.0-1.5 eV) and CdTe (Eg=1.44 eV) is one of the major goals of research devoted to photovoltaics. These cells rely on transparent electrodes made of transparent conductive oxides (TCO) whose high transmittance and low resistivity result in a high short circuit current and fill factor enabling high cell efficiency.

In TCOs absorption in the near infrared (NIR) and visible spectral region is caused by the free electrons and is influenced by their density and mobility inside the host lattice. Due to this inter-relation of optical and electrical properties TCOs with highest carrier mobility at moderate electron densities (~5x10<sup>20</sup> cm<sup>-3</sup>) are required to simultaneously reach low resistivities and high NIR transmittance. Furthermore the deposition process used should be cost effective and scalable to large area substrates.

Therefore a reactive magnetron sputtering method using metallic Zn/Al alloy targets was developed to achieve high carrier mobilities (µ~45 cm²/Vs) in ZnO:Al (AZO) thin films [1], which is comparable to values achieved with other methods like RF magnetron sputtering or pulsed laser deposition.
Mass spectrometry and high accuracy capacitive pressure sensing together with a variation of the magnetron discharge parameters allowed for a fine control of oxygen partial pressure (p_O2). The dependence of the films electrical properties on the substrate temperature (T_S), the Al content in the sputter targets and p_O2 have been investigated systematically by Hall-effect measurements. Spectroscopic ellipsometry was used to determine film thickness and optical properties. The film structure, morphology and elemental composition was analysed by various methods including AFM, XRD, X-TEM, ERDA and RBS. Analysis of the film composition together with Hall-effect data was used to estimate Al donor activation.

Results show that there are optimum values of T_S and p_O2 at which films with resistivities down to ~2.3x10<sup>-4</sup> Ohm*cm and free electron densities of ~6.0x10<sup>20</sup> cm<sup>-3</sup> were achieved. A shift of these optimum growth parameters and the resulting film properties with the target Al content has been detected. The observed limit of mobility in polycrystalline AZO is discussed in terms of ionized impurity scattering and clustering as well as grain boundary limited transport.
Recent investigations of Al concentration in the films and local bonding structure, revealed by XANES seem to explain the well known deterioration of resistivity in AZO at elevated substrate temperatures or after annealing.]]></dc:description>

<dc:description><![CDATA[Es wurde ein Modell zur realistischen Beschreibung der Kühlmittelvermischung innerhalb des Reaktordruckbehälters eines Druckwasserreaktors entwickelt und validiert. Dieses schnell rechnende Modell basiert auf dem Prinzip der linearen Superposition der Antwortfunktionen auf Dirac-Impuls-ähnliche Störungen der Kühlmittelparameter. Es wurde in den gekoppelten Programmkomplex DYN3D/ATHLET als Schnittstelle zwischen dem eindimensionalen Thermohydraulikprogramm ATHLET und dem dreidimensionalen neutronenkinetischen Kernmodell DYN3D eingebunden und simuliert in effizienter Weise die Vermischung des Kühlmittels innerhalb des RDB. 
Für die Analyse von hypothetischen Borverdünnungsstörfallen wurde eine Methodik entwickelt, die auf dem neuen Modell zur Beschreibung der Kühlmittelvermischung basiert. Diese Methodik besteht aus einer Kombination von stationären und transienten Rechnungen, in denen die Vermischung der deborierten Pfropfen auf dem Weg zum Reaktorkern in realistischer Weise simuliert wird. Über die Variation der Größe des deborierten Kühlmittelpfropfens kann der gewünschte Grad an Konservativität für die Analysen vorgegeben werden.
Diese neue Methodik wurde erfolgreich auf zwei verschiedene Borverdünnungsstörfalle angewandt. Neben dem Start der ersten Hauptkühlmittelpumpe bei Vorhandensein eines deborierten Kühlmittelpfropfens im kalten Strang des Primärkreislaufes wurde ein Deborierungsstörfall im Nachkühlbetrieb betrachtet. In beiden Fällen zeigten die Ergebnisse der Parameterstudie für eine generische Kernkonfiguration, dass es selbst bei Annahme des maximal möglichen Pfropfenvolumens zwar zur Rekritikalität des abgeschalteten Reaktors aber nicht zu einer unzulässigen Erhöhung der Hüllrohrtemperatur kommt. Wesentliche Ursache dafür ist die Verwendung realistischer zeitabhängiger Verteilungen der Borkonzentration am Eintritt in jedes Brennelement.]]></dc:description>

<dc:date>2001</dc:date>
<dc:description><![CDATA[Real-time ellipsometry (RTE) in combination with particle flux measurement is applied to ion beam assisted deposition (IBAD) of boron nitride (BN) films. RTE is used as a toll for process diagnostic to improve the deposition stability. A novel technique for the determination of absolute density depth profiles from dynamic growth rate data and film forming particle flux is employed. From real-time cantilever curvature measurement and simultaneously recorded film thickness data instantaneous stress depth profiles are derived with a depth resolution in the nm--range. The synergistic effects on the information obtained from RTE, particle flux, and cantilever bending data are demonstrated. The density of turbostratic BN (tBN) is found to increase slightly with film thickness while the compressive stress decreases, indicating an increasing quality and/or size of crystallites in the course of film growth. Refractive index and density depth profiles in cubic BN (cBN) films correspond perfectly to structural information obtained from dark field TEM graphs. The established tBN/cBN 2-layer model is found to be a crude approximation that has to be replaced by a 3-layer model including nucleation, grain growth, and coalescence of cBN. The instantaneous compressive stress in a homogeneous tBN film is found to decrease while the density increases during growth. The instantaneous compressive stress depth profiles in cBN films are more complex and not easy to understand but reliable information on the structural evolution during growth can be extracted.]]></dc:description>

<dc:description><![CDATA[An intensity modulated focused ion beam (FIB) which is hitting the surface of a solid, heats up a small near subsurface region to a temperature which is sufficient for thermal elastic wave generation.  The measurement of these waves can be used for analysis and imaging of surface as well as subsurface structures in the material. The modified FIB equipment IMSA-100 working with 35 keV Ga+ and Au+ ions, respectively, and a current of about 3 nA was employed to obtain acoustic images from structures on silicon and glass targets. The acoustic signals were detected using a PZT transducer delivering an output voltage of 50 - 100 nV. The modulation frequency was varied in the range of 60 - 170 kHz. The obtained lateral resolution of the ion acoustic images at these frequencies was about 15 µm on silicon and about 7µm on glass, respectively. Furthermore some estimations due to the reachable resolution  and a short description of the set-up is given.]]></dc:description>

<dc:description><![CDATA[The data of direct single-photon measurements of the WA98 collaboration in the reaction Pb(158 AGeV) + Pb are analyzed within a thermal model with a minimum number of parameters adjusted to the dilepton data obtained by the CERES and
NA50 collaborations in the reactions Pb(158 AGeV) + Au, Pb.
The agreement of our model with the WA98 data points to a unique  large thermal source emitting electromagnetic radiation observable in both the real and virtual photon channels.

<dc:source><![CDATA[Physical Review C, Vol. 62, 054314, 1-10]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[High-spin states of the nucleus $^{88}$Sr have been studied via the 
reaction $^{80}$Se($^{11}$B,$p$2$n$) at a beam energy of 45 MeV. Gamma-rays 
were detected with the six-detector array OSIRIS CUBE. The level scheme of 
$^{88}$Sr has been extended up to $E \approx$ 11 MeV and $J = 17$.
Mean lifetimes of three levels have been determined using the 
Doppler-shift-attenuation method. The level structures in $^{88}$Sr have
been interpreted in terms of the shell model. The calculations were performed
in the configuration space $(0f_{5/2}, 1p_{3/2}, 1p_{1/2}, 0g_{9/2})$ for 
the protons and $(1p_{1/2}, 0g_{9/2}, 1d_{5/2})$ for the neutrons. These 
calculations describe the high-spin level sequences linked by $M1$ transitions
with strengths of $B(M1) \leq 1.4$  W.u. as multiplets of seniority 
$\upsilon$ = 4 and 6 states including proton configurations and neutron-core 
excitations.

<dc:description><![CDATA[The investigation of the correlations between magnetic and lattice degrees of freedom provides a better understanding of the underlying physics of frustrated and low-dimensional spin systems. Ultrasound experiments are proven to be a powerful tool to probe the spin-lattice interactions and lattice instabilities. Here, we will present some recent outcome of our ultrasound studies performed at high magnetic fields. We report results of our investigations of the frustrated spin system CdCr<sub>2</sub>O<sub>4</sub> [1]. This material shows a wide magnetization plateau, from 28 to 58 T, at one half of the full moment of S = 3/2 Cr<sup>3+</sup>. We further present results for the low-dimensional quantum antiferromagnets Cs<sub>2</sub>CuCl<sub>4</sub> [2] and NiCl<sub>2</sub>-4SC(NH<sub>2</sub>)<sub>2</sub> [3]. The spin-strain coupling is discussed in frame of the exchange-striction mechanism.]]></dc:description>

<dc:title><![CDATA[Validation of the RELAP5 code for the modeling of flashing-induced instabilities under natural-circulation conditions using experimental data from the CIRCUS test facility]]></dc:title>
<dc:source><![CDATA[Nuclear Engineering and Design 243(2012), 168-175]]></dc:source>
<dc:date>2012</dc:date>
<dc:description><![CDATA[This paper reports on the use of the RELAP5 code for the simulation of flashing-induced instabilities in natural circulation systems. The RELAP 5 code is intended to be used for the simulation of transient processes in the Russian RUTA reactor concept operating at atmospheric pressure with forced convection of coolant. However, during transient processes, natural circulation with flashing-induced instabilities might occur. The RELAP5 code is validated against measurement data from natural circulation experiments performed within the framework of a European project (NACUSP) on the CIRCUS facility. The facility, built at the Delft University of Technology in The Netherlands, is a water/steam 1:1 height-scaled loop of a typical natural-circulation-cooled BWR. It was shown that the RELAP5 code is able to model all relevant phenomena related to flashing induced instabilities. The magnitude and frequency of the oscillations were reproduced in a good agreement with the measurement data. The close correspondence to the experiments was reached by detailed modeling of all components of the CIRCUS facility including the heat exchanger, the buffer vessel and the steam dome at the top of the facility.]]></dc:description>

<dc:description><![CDATA[An experimental and theoretical study of the transport of mineral wool fibre agglomerates in nuclear power plant containment sumps is being performed.  A racetrack channel was devised to provide data for the validation of numerical models, which are intended to model the transport of fibre agglomerates.  The racetrack channel provides near uniform and steady conditions that lead to either the sedimentation or suspension of the agglomerates.  Various experimental techniques were used to determine the velocity conditions and the distribution of the fibre agglomerates in the channel. The fibre agglomerates are modelled as fluid particles in the Eulerian reference frame. Simulations of pure sedimentation of a known mass and volume of agglomerations show that the transport of the fibre agglomerates can be replicated. The suspension of the fibres is also replicated in the simulations; however, the definition of the fibre agglomerate phase is strongly dependent on the selected density and diameter. Detailed information on the morphology of the fibre agglomerates is lacking for the suspension conditions, as the fibre agglomerates may undergo breakage and erosion. Therefore, ongoing work, which is described here, is being pursued to improve the experimental characterisation of the suspended transport of the fibre agglomerates.]]></dc:description>

<dc:description><![CDATA[To study the kinetics of Al ion nitriding, a series of experiments has been performed at fixed ion beam parameters using substrate temperatures varied from 250 °C to 400 °C at intervals of 50 °C. The nitride layers have been analysed by nuclear reaction analysis (NRA), elastic recoil detection analysis (ERDA), x-ray diffraction (XRD) and scanning electron microscopy (SEM). Depending on the experimental conditions, the nitriding kinetics shows different character: controlled by the delivery of N ions or by the diffusion of Al atoms. Furthermore, the growth of the nitride layer is limited due to the bad layer adhesion. XRD analysis reveals the formation of a hexagonal AlN-phase plus a small  fraction of the cubic AlN-phase. ]]></dc:description>

<dc:description><![CDATA[The amorphous non-equilibrium state of the system Fe/Al is studied in bulk and thin-film systems. For bulk samples prepared by ion-beam mixing of laser-deposited multilayers, a bcc solid solution is found
for alloys with up to 70 at.% Al.  Around 75 at.% Al a Fe2Al5-like crystalline phase is found. An amorphous state with Fe2Al5-like short-range order is found for 80 at.% Al. In thin films, e.g. the amorphous Al-rich transition layer of a laser-deposited Fe/Al multilayer, the amorphous state can exist for
up to 30 at.% Fe due to the high interfacial energy. By ion-beam mixing at low temperatures (about 140 K) an oversaturation of 40 at.% Fe could be achieved.       ]]></dc:description>

<dc:description><![CDATA[Classical molecular dynamics simulations were performed to investigate elementary ion-beam-induced defect production in 3C- and 4H-SiC. A modified Tersoff potential was used to model the interactions between the atoms. For cases where C and Si primary knockon atoms (PKAs) start parallel or antiparallel to the [0001] direction the threshold PKA energy for defect formation as well as the final defect configuration and its formation energy were determined. The elementary defects observed in 3C-SiC and 4H-SiC differ significantly whereas the corresponding threshold PKA energies and the formation energies of the configurations are mostly rather similar. In 4H-SiC new sites for C and Si interstitials were found: One site is situated between two C<SUB>3</SUB>Si<SUB>3</SUB> hexagonal rings, the other between a C<SUB>3</SUB> and a Si<SUB>3</SUB> trigonal ring. ]]></dc:description>

<dc:description><![CDATA[For focused ion beam applications of Erbium as well as of several metal ions which are of interest for optical and semiconductor investigations a liquid metal ion source operating with an Er-stainless steel alloy was developed and investigated. This alloy consists of a mixture of Er70Fe22Cr5Ni3 and has a melting point of about 860°C. The wetted needle type tungsten emitter showed a stable emission behaviour down to 1µA emission current. The I-V characteristics, the temperature dependence of the extraction voltage, the mass spectrum, and the energy spread of the main beam components depending on the emission current were investigated. While in the case of singly charged metal ions the beam is not defined due to isotope interference in the case of doubly charged ions the species well separated for focused ion beam applications are available.]]></dc:description>

<dc:source><![CDATA[The Journal of Computational Multiphase Flows 2(2010)3, 131-143]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Stratified two-phase flow regimes can occur in the main cooling lines of Pressurized Water Reactors, Chemical plants and Oil pipelines. A relevant problem occurring is the development of wavy stratified flows which can lead to slug generation. In the last decade, the stratified flows are increasingly modelled with computational fluid dynamics (CFD) codes. In CFD, closure models are required that must be validated. The recent improvements of the multiphase flow modelling in the ANSYS CFX code make it now possible to simulate these mechanisms in detail. In order to validate existing and further developed multiphase flow models, high-resolution measurement data is needed in time and also in space. For the experimental investigation of co-current air/water flows, the HAWAC (Horizontal Air/Water Channel) was built. The channel allows in particular the study of air/water slug flow under atmospheric pressure. Parallel to the experiments, CFD calculations were carried out. The two-fluid model was applied with a special turbulence damping procedure at the free surface. An Algebraic Interfacial Area Density (AIAD) model on the basis of the implemented mixture model was introduced, which allows the detection of the morphological form of the two phase flow and the corresponding switching via a blending function of each correlation from one object pair to another. As a result this model can distinguish between bubbles, droplets and the free surface using the local liquid phase volume fraction value. The behaviour of slug generation and propagation was qualitatively reproduced by the simulation, while local deviations require a continuation of the work. The creation of small instabilities due to pressure surge or an increase of interfacial momentum should be analysed in the future. Furthermore, experiments with pressure and velocity measurements are planned and will allow quantitative comparisons at other superficial velocities.]]></dc:description>

<dc:description><![CDATA[Co/Cu multilayers were prepared by crossed-beam pulsed laser deposition and
characterized by high-angle X-ray diffraction as well as specular and non-specular reflection. The as-deposited structure has
a higher rms roughness than magnetron sputtered Co/Cu multilayer. In
general the roughness of the interface is described by a very large lateral correlation length and a high jaggedness.
Ion-beam mixing of the multilayers with 150 keV Cu ions and a fluence of
up to 5e15 Cu/cm^2 leads to the formation of a granular system of superparamagnetic Co clusters in Cu, as it is shown by magnetic
measurements.        ]]></dc:description>

<dc:description><![CDATA[  Soft hadron production is described  as a two-step process, where  the
  interaction  of the   partonic constituents of  the colliding  hadrons
  leads to the production  of intermediate subsystems (fireballs), which
  decay subsequently into hadrons.   The  weights of the  various  final
  states are derived from the corresponding phase-space factors modified
  by  empirical transition elements. The  results compare well with data
  at  energies    between   particle  production  thresholds   and   ISR
  energies. Special emphasis is put on correlation data, which offer the
  opportunity  to  shed  some  light on   the question  whether particle
  production proceeds via fireballs or strings.

<dc:source><![CDATA[18th International Conference on Ion implantation Technology (IIT 2010), 06.-11.06.2010, Kyoto, Japan]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[One of the main goals of materials research using ion beams is to synthesize nanostructures, for example semiconducting or metallic nanocrystals (NCs) in insulating films. A great effort is currently devoted to NC fabrication for micro- and optoelectronics by ion beam synthesis (IBS), because this method is compatible with modern CMOS technology. The present contribution addresses the Si NC formation by a non-conventional IBS approach of ion beam mixing of SiO2/Si interfaces in thin gate oxides [1], with special emphasis on well-controlled size and position tailoring as well as their application in non-volatile nanocrystal memories and in light emitting field-effect transistors (LEFET). Compared to conventional Si NC synthesis by Si+ ion implantation into the gate oxide [2], we take advantage of this self-alignment process, i.e., the Si NCs are formed in SiO2 at a well-controlled small distance of ca. 2 nm from the Si/SiO2 interfaces. 
In order to implement our novel technique in CMOS technology, ion irradiation through a MOS-FET stack of 50nm poly-Si/15nm SiO2/Si substrate was performed with 50 keV Si+ ions. The ion beam mixing of the upper poly-Si/SiO2 interface and the lower SiO2/(001)Si interface leads to Si excess in the gate oxide.  Subsequent rapid thermal annealing reforms sharp interfaces and separates the excess Si from SiO2. Adjacent to the recovered interfaces, 3-4 nm thick SiO2 zones denuded completely of excess Si have been found, whereas the more distant tails of excess Si form well-aligned narrow layers of NCs with 2-3 nm diameter. The self-alignment of the NC layers with the SiO2/Si interfaces allows to control shorter (direct) tunneling distances between the NCs and the Si electrodes with the potential of faster devices operating at reduced voltages.
The Si NC MOSFETs with an active gate area of 20x20 µm2 were fabricated as nMOSFET devices in a standard 0.6 µm CMOS process line. Their electrical characteristics have been evaluated in terms of write/erase voltage, duration of the programming time, endurance and retention for different ion irradiation and annealing conditions.  For the investigation of the light-emitting characteristics of the same nMOSFETs, an AC voltage was applied to the gate in order to inject charges of both polarities into the NCs. AC voltage and frequency dependent electroluminescence spectra in the wavelength region of 400-1000 nm were recorded for different annealing conditions.  The performance of the Si NC memories and LEFETs with further possibilities of optimization of efficient charge storage and light emission properties will be discussed.]]></dc:description>

<dc:source><![CDATA[Chemical Engineering and Technology 23(2000)845-849]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[A new one-dimensional model suitable for practically orientated simulations of transient multiphase flows within vessels was developed. The model bases on a new developed specific Particle-In-Cell method. The equations of transport are solved free of numerical diffusion. This property and the distinction between continuous and dispersed phases make an implicit reflection of discontinuities as e.g. the top level of the mixture possible. Flexible interfaces allow a convenient coupling of this model with constitutive correlations and models for special phenomena. There is also an interface, which enables the implementation of foam models. By such a model the generation decay of foam at the top level of the mixture may be simulated. A special goal of the code is the transient simulation of emergency relief from chemical reactors. For this reason the code was equipped with models for pressure calculation, conservation of energy, phase transfer, bubble generation, bubble growth, coalescence, drift of the phases, heat release from the vessel wall, discharge and homogeneous chemical reactions. ]]></dc:description>

<dc:source><![CDATA[Annals of Nucl. Energy 27 (2000) 1441-1457]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[The influence of fluid-structure interaction (FSI) on vibration modes is investigated using the finite element method. The method of modelling is verifyed by comparing the finite element results with the exact analytical solution of a simple fluid-shell test system. It is shown that the method of coupling between structural and fluid elements is important for the accuracy of the eigenfrequencies. The vibration modes of the reactor pressure vessel and its internals of a WWER-1000 type reactor are calculated. The FSI causes a considerable down shift of the shell mode frequencies of pressure vessel, core barrel and thermal shield. Some bending modes which exhibit a relative displacement between pressure vessel and core barrel or between core barrel and thermal shield are significantly affected too. Some simple analytical approaches to consider the FSI are discussed on the basis of the numerical results. ]]></dc:description>

<dc:description><![CDATA[Natural IIa diamond was implanted at 90 keV to 1 1015 N+/cm2 and subsequently at 150 keV to 3 1017 Si+/cm2 at a temperature of 900°C. The structure of the implanted diamond region was investigated by high resolution cross-sectional transmission electron microscopy, Raman- and infrared absorption spectrometry. A buried layer with crystalline 3C-SiC domains in perfect epitaxial  relation to the diamond substrate was detected.  Amorphization and graphitization was completely prevented by the elevated temperature during the implantation. Resistance measurements demonstrated low electrical resistivity in the implanted regions. ]]></dc:description>

<dc:date>2000</dc:date>
<dc:description><![CDATA[We report on a nuclear resonance fluorescence experiment on the semi-magic odd-mass fp-shell nucleus 51V. The
detected dipole strength distribution is discussed on the basis of modern shell-model calculations employing a
model space allowing for excitations of protons and neutrons from the 1f7/2 to the (2p1/2,2p3/2,1f5/2) shells. The
calculations indicate that the main body of transitions is of magnetic dipole type, and they are capable of
reproducing the observed distribution well. Possible electric dipole and quadrupole contributions are also
discussed.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[A correlation between the grain orientation and the out-of-plane magnetic properties of nitrogen-enriched polycrystalline austenitic stainless steel surface is performed. Due to the competition between the magnetocrystalline anisotropy, the exchange and dipolar interactions, and the residual stresses induced by nitriding, the resulting effective magnetic easy-axis can lay along unusual directions. It is also demonstrated that, by choosing an appropriate stainless steel texturing, arrays of ferromagnetic structures with out-of-plane magnetization, embedded in a paramagnetic matrix, can be produced by local plasma nitriding through shadow masks.]]></dc:description>

<dc:description><![CDATA[The TEM study of titanium contained ZSM-5 zeolite before and after hydrothermal treatment was performed. The use of different TEM techniques - such as conventional TEM, HRTEM and EDX line scans provides important information about the zeolite catalyst consisting from several phases. The hydrothermal treatment of zeolite powder leads to strong changes in the morphology of the constituting particles. They are characterised by a homogeneous structure before hydrothermal treatment while the occurrence of holes after thermal treatment was observed. These changes lead to the enrichment of zeolite with titanium that enhance its catalytic activity. Some of the titanium surplus precipitates as TiO2 anatase nanoparticles within the holes.]]></dc:description>

<dc:source><![CDATA[JP 4090077 B2]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[Mit der Erfindung wird ein Gittersensor vorgestellt, in dem die Elektroden in Form von elektrisch leitfähigen Gitterstäben bzw. Drähten in zwei oder drei Ebenen parallel zueinander angeordnet und sowohl gegenüber ihrer Halterung als auch gegeneinander elektrisch isoliert sind. Erfindungsgemäß sind die Elektroden der einzelnen Ebenen zueinander in einem Winkel von vorzugsweise 90° angeordnet. Eine der Ebenen, im Fall von drei Ebenen die mittlere, ist dabei als Erregerebene mit einem Impulsgenerator verbunden, während die weitere(n) Ebene(n) als Empfängerebene(n) mit einer Auswerteelektronik gekoppelt ist (sind).
Bezüglich des Verfahrens zur Signalgewinnung besteht die Erfindung darin, daß  die Elektroden der Erregerebene nacheinander mit einem symmetrischen bipolaren Rechteckimpuls  angesteuert werden, wobei alle nicht angesteuerten Elektroden niederohmig mit Nullpotential verbunden sind. Die Bestimmung der örtlichen Leitfähigkeit erfolgt in unmittelbarer Umgebung der Kreuzungspunkte von jeweils einer Erregerelektrode auf alle Empfängerelektroden durch Messung des Stromeintrags auf alle Empfängerelektroden gleichzeitig. Die Anregung der einzelnen Erregerelektroden erfolgt zeitlich nacheinander, die gemessenen Stromeinträge an allen Kreuzungspunkten werden dann durch eine elektronische Auswerteeinheit zu einer Leitfähigkeitsverteilung über den erfaßten Strömungsquerschnitt zusammengefügt.
Mit der Erfindung ist die Ermittlung der Leitfähigkeitsverteilung innerhalb des vom Gittersensor begrenzten Querschnitts mit hoher Auflösung und Meßfolge möglich. Die erhaltenen Meßwerte repräsentieren die lokalen Leitfähigkeitswerte direkt und erfordern keine zusätzliche Nachberechnung mittels tomographischen Rekonstruktionsalgorithmen.]]></dc:description>

<dc:description><![CDATA[High-spin states in 72Br were studied with the EUROBALL III spectrometer . The negative-parity band
observed in this experiment displays a signature inversion around spin I = 16. The interpretation within cranked Nilsson-Strutinsky approach shows that this signature pattern is a signal of a substantial triaxial shape change with increasing spin where the nucleus evolves from a triaxial shape with rotation around the intermediate axis at low spin 
through an axially symmetric prolate one to a triaxial shape 
but with rotation around the shortest principal axis at high spin.
This is the first case in which signature inversion was clearly related to varying gamma deformation.]]></dc:description>

<dc:description><![CDATA[The photoluminescence (PL) and PL excitation (PLE) properties of Sn-implanted SiO2 layers thermally grown on crystalline Si has been investigated and compared with those from Ge- and Si-implanted SiO2 layers. In detail, the violet PL of Sn-implanted SiO2 layers is approximately 2 and 20 times higher than those of Ge- and Si-implanted SiO2 layers, respectively. Based on PL, PLE and decay time measurements the violet PL is interpreted as due to a triplet-singlet transition of the neutral oxygen vacancy (NOV) typical for Si-rich SiO2 and similar Ge- and Sn-related defects in Ge- and Sn-implanted SiO2 films. The enhancement of the blue-violet PL within the isoelectronic row of Si, Ge and Sn will be explained by means of the heavy atom effect.]]></dc:description>

<dc:title><![CDATA[Intrauterine growth restriction induces up-regulation of cerebral aromatic amino acid decarboxylase activity in newborn piglets: [<SUP>18</SUP>F]fluorodopa positron-emission-tomographic study]]></dc:title>
<dc:source><![CDATA[Pediatric Research 49 (2001) 474-480]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[There is evidence that intrauterine growth restriction (IUGR) is associated with altered dopaminergic function in the immature brain. However, the relevant enzyme activities have not been measured in the living neonatal brain together with brain oxidative metabolism. Therefore <SUP>18</SUP>F-labelled 6-fluoro-L-3,4-dihydroxyphenylalanine (FDOPA)  was used together with positron-emission-tomography to estimate the activity of the aromatic amino acid decarboxylase in the brain of 10 newborn IUGR piglets (2 to 5 days old; body weight 908±109g) and in 10 normal-weight (3 to 5 d old; body weight 2142±373g) newborn piglets. The regional transport of FDOPA to the brain and the clearance rate of labeled metabolites from brain tissue were broadly similar in the two groups. However, the regional rate constant for back flux from the brain was markedly increased in IUGR piglets for striatum (72%) and frontal cortex (83%) (p < 0.05). Furthermore, the rate constant for conversion of FDOPA to fluordopamine was markedly increased (between 48 % in cerebellum and 91 % in mesencephalon, p < 0.05) in all brain regions of IUGR piglets studied. 
Thus, it is suggested that IUGR induces an up-regulation of amino acid decarboxylase activity that is not related to alterations in brain oxidative metabolism.

<dc:description><![CDATA[Anhand der Bergbaufolgeschäden des ehemaligen Kali- und Steinsalzbergbau im Raum Staßfurt (Sachsen-Anhalt) wurden im Rahmen des Forschungsverbundvorhaben Dynamik abgesoffener oder gefluteter Salzbergwerke und ihres Deckgebirgsstockwerks Ursachen, Prozesse und Auswirkungen der Bergschäden exemplarisch und umfassend untersucht. 
Ein verbessertes Prozessverständnis, das auf kleinskaligen experimentellen Untersuchung der Strukturen und Prozesse im Labormaßstab und damit verbundenen Modellierungen beruht, soll zur Aufklärung des Geschehens und möglicher Folgen beitragen.
Zu diesem Zweck wurde in enger Zusammenarbeit mit dem Teilvorhaben zur strukturbezogenen Prozessmodellierung eine Methode zur direkten räumlich aufgelösten und quantitativen Prozessbeobachtung entwickelt und angewendet. Hierfür wurde als bildgebendes Verfahren die Positronen-Emissions-Tomographie (PET) eingesetzt. Hierfür wird ein Teil des injizierten Fluids mit Spuren eines Radiotracers markiert. Die Tracerkonzentration kann zerstörungsfrei, mit höchstmöglicher Empfindlichkeit und einem geeignetem Auflösungsvermögen in Raum und Zeit abgebildet werden. Der Prozess wird durch den Tracer auf geringst mögliche Weise beeinflusst und es wird ein realistisches Bild der Tracerverteilung, bzw. des Fließverhaltens, mit einer räumlichen Auflösung von 1 mm und einer zeitlichen Auflösung von 60s erzeugt.
Dieses Fließverhalten lässt sich mit räumlich heterogenen und prozessabhängigen Verteilungen von Parametern, wie effektiven Volumina, Permeabilitäten, Abstandsgeschwindigkeiten und Dispersionsraten beschreiben. Einem besseren Prozessverständnis dient insbesondere der Abgleich mit mit Lattice-Boltzmann-Simulationen der Fließprozesse, die auf hochauflösenden computertomographischen (µXCT) Messungen der internen Struktur der identischen Bohrkerne beruhen. Dieser Vergleich von PET-Messdaten mit Lattice-Boltzmann - Simulationsdaten, der zugleich eine Skalenübertragung um etwa drei Größenordnungen bedeutet, erfolgt mit geostatistischen Methoden.
Nicht in jedem Fall war dieser Abgleich zwischen Simulation und Experiment möglich: Während in klüftig-porösen Materialien gewöhnlich mit beiden Methoden räumlich stark differenzierte präferentielle Fließwege im Kluftsystem gefunden wurden, konnte in eher mikrostrukturell ausgeprägten Materialien trotz messbarer Permeabilität gelegentlich kein verbundener Porenraum aus den CT-Bildern segmentiert und somit keine LBM-Simulation durchgeführt werden. In diesem Fall zeigte die PET-Untersuchung ein diffuses Ausbreitungsverhalten des Tracers.]]></dc:description>

<dc:description><![CDATA[The Ge nanoparticles fabricated by ion implantation technique in SiO2 thin film crystallise after irradiation with high energetic electron beam. The crystallisation process depends on the irradiation dose and intensity. Irradiation with a dose above 6x103 C/cm2 results in cluster growths and above 4x104 C/cm2 in crystallisation. An irradiation of intensity below 150 A/cm2 leads to the crystallisation of Ge nanoparticles in the form of single crystals. For irradiation intensities above this value the formation of twinned and multiply twinned particles (MTP) was observed.]]></dc:description>

<dc:source><![CDATA[Biometals 2010, 25.-30.07.2010, Tucson, USA]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Plants are able to accumulate uranium (U) in roots and shoots /1/. Hence, we could detect an accumulation of this metal inside suspension cells of canola (Bassica napus) via fluorescence microscopy. Such uptake of highly toxic heavy metals requires skilled complex cellular defense mechanisms.
One example is the formation of metal complexes in the cytosol. A prominent candidate might be the tripeptide glutathione (GSH) bearing metal chelating functionalities like carboxylato- and thiol residues. Whereas at pH 5.7 the formed complex was stable over 6 hours, the initial complexes at pH > 6.0 degraded within 30 minutes. A reduction of U(VI) by GSH seems to be possible, because of strong spectral changes contributed by thiolate functionality. However, the spectra of the later formed chelates indicated an involvement of SH-groups in U complexation. 
This is necessary for the formation of phytochelatins based on GSH. These metal binding peptides could be detected by HPLC in the cytosol 24 hours after U contact. U was bound to these peptides revealed by gelelectrophoresis of isolated cytoplasmic peptides and subsequent Laser-induced Fluorescence Spectroscopy. Despite these GSH consuming processes during U contact, the cytoplasmic GSH content decreased only slightly but not significantly compared to the control. Artificial depletion of GSH induced an up to twofold increased metabolic activity of cells challenging with U concentrations ≤ 10 µM whereas higher U contents dramatically reduced the metabolism. These data underlines the tight cellular regulation and the importance of GSH in maintaining defense reactions against U.

<dc:description><![CDATA[Mn doped Ge (Ge:Mn) is a promising candidate for a ferromagnetic semiconductor compatible with silicon technology, since Mn acts as a magnetic ion as well as a double acceptor. Whereas ferromagnetism above room temperature has been evidenced by magnetization measurements, the transport behavior is entirely different from the GaAs:Mn system [1], the prototype of a ferromagnetic semiconductor.

We have prepared a series of Ge:Mn layer by Mn ion implantation into near-intrinsic Ge substrates, at 350 °C (resulting in Mn5Ge3 clusters) and -40 °C (without precipitates) [1-4]. The Mn concentration ranges from 0.004% to 10%. For samples with 10% Mn, flash lamp and pulsed laser annealing (PLA) has been applied. We obtained three kinds of samples: (1) very dilute Ge:Mn where no ferromagnetic coupling can be expected [1]; (2) nanocrystalline Mn5Ge3 embedded inside the Ge matrix [2]; and (3) diluted Ge:Mn together with Mn-rich spinodal phases [3]. Indeed all samples show p-type conductivity with a hole concentration ranging from 1018 to 1020 cm<sup>3</sup>. The highest concentrations above 1020 cm<sup>3</sup> can only be achieved by PLA. In the sample with the largest hole concentration of 2.1×1020 cm<sup>3</sup>, we observed a one-to-one correspondence between the hysteresis in magnetization, magnetoresistance and Hall resistance below 10 K [3, 4]. We argue that the hole concentration is the critical parameter to establish carrier mediated ferromagnetism in Ge:Mn [4]. In addition to the compatibility to Si technology, ion implantation followed by PLA is an established scalable chip technology and may have a significant industry impact.

<dc:description><![CDATA[Our investigation supporting the feasibility of the in-situ
 PET monitoring in proton therapy is presented. We simulated by means of the FLUKA code the amount and the spatial distribution of the main  ß+ emitters created in PMMA targets by  protons at  typical therapeutic energies. The quantitative  comparison   with the   activation  induced by 12C  ions of energies corresponding to the same range shows that the available signal   at the same physical dose level should be up to two times more intense for protons than that actually successfully used for the control of  carbon ion therapy    at  GSI Darmstadt. The spatial correlation between the activity and the dose profile  for protons is poorer than  for 12C nuclei. However,  an important  check of the particle range, dose localization and stability of the treatment during all the fractions seems to be possible.

<dc:title><![CDATA[Roughness evolution in amorphous silicon films grown by (biased) DC magnetron sputtering]]></dc:title>
<dc:source><![CDATA[12th International Conference on Plasma Surface Engineering, 13.-17.09.2010, Garmisch-Partenkirchen, Germany]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Control over surface roughness (σ) is a critical issue in many physical, chemical, biological and technological processes. Regarding relevant systems, silicon is a model material that finds a wide range of applications in microelectronic and photovoltaic devices. Further, the growth of amorphous silicon (a-Si) could yield ultrasmoothness, a keystone for the production of ultrathin films, in analogy to amorphous diamond-like carbon [1]. Based on this motivation, we have studied the roughness evolution of a-Si films prepared by DC magnetron sputtering at low (LP) and high (HP) plasma pressures (10-3 and 3×10-3 mbar, respectively). The morphological analysis was carried out by atomic force microscopy and interpreted in the framework of dynamic scaling concepts [2]. The film thickness evolution was analyzed by ex-situ spectroscopic ellipsometry, providing also information on the disorder character of the films. Smooth (σ<0.2nm) films were produced at LP whereas rougher surfaces were grown at HP. The growth exponent [σ(t)~tβ] was close to 0.25 at LP, compatible with a morphology controlled by surface diffusion relaxation processes, whereas HP yielded considerably higher β characteristic of unstable growth. The distinct evolution should be related to the lower mean free path in the gas phase at HP, which alters the incidence angle and/or size of the particles condensing at the substrate and can result in shadowing effectsduring growth [3]. Finally, a negative DC bias voltage (-400V) applied to the substrate at HP changes drastically the surface morphology to ultrasmooth (σ~0.12 nm) during the whole temporal window sampled, resulting in β~0 (i.e. suppressing surface roughening). The latter could be consistent with the Edwards-Wilkinson interface equation [2]. This evident surface smoothing could be ascribed to ion-induced downhill currents that preferentially erode prominent features [1].

<dc:date>2002</dc:date>
<dc:description><![CDATA[The Master Curve concept allows to quantify the variation of fracture toughness with the temperature throughout the  ductile-to-brittle transition region. Limit curves of fracture tough ness for defined failure probabilities and a reference temperatures can be determined using this method. Thus, fracture mechanical values can be supplied for an integrity assessment of structural components. This paper presents the application of the master curve concept to the reference temperature determination over the thickness of RPV steel plate. It was shown that the master curve concept is applicable for the  fracture mechanical characterisation of material with different microstructures using small test specimens. The influence of the material homogeneity and the test temperature on the resulting reference temperature was investigated.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[The 3,4-disubstituted piperidine framework plays an important role in many fields of pharmaceutical research[1] The ring opening of a conformationally rigid oxirane, annelleted to an N-protected six membered piperidine by an amine nucleophile, is a powerful method for establishing a trans-beta-aminoalcohol at the 3,4-position. Compounds derived from azavesamicol (trozamicol), which have been reported as usefulligands for the vesicular acetylcholine transporter (VAChT),[2] are displaying a 3-amino-piperidin-4-ol as a consistent structural feature. As part of our efforts in the search for new VAChT ligands for F18-PET (positron emission tomography) we have found a regioselective ring opening approach applying 3-(4-fluorobenzyl)-7-oxa-3-azabicyclo[4.1.0]heptane, which was utilized for a new 4-step synthesis of 4-fluorobenzyltrozamicol.
In contrast to former methodology, processing a common acyl[3] or carbamoyl[4] protective group at the piperidine nitrogen, we choose an N-benzyl protection. Starting from pyridine, which was converted to an N-4-fluorobenzylpyridinium salt, we obtained the corresponding N-protected 1,2,3,6-tetrahydropyridine via a standard hydrogenation using NaBH4 in EtOH. It was possible to epoxidize the olefine in high yield without interfering the basic tertiary amine, if applying trifluoroacetic acid in combination with its anhydride and H2O2-urea. As expected, the LiCIO4 assisted reaction of 1-aralkyl-3,4-epoxypiperidines with a series of aliphatic and aromatic amines in acetonitril led to a regioselective attack at position 4 of the piperidine to obtain 1-aralkyl-4-amino-piperidin-3-ol.[5] However, if applying EtOH as a protic solvent, without a coordinating Li-cation as additive, the inverse reg ioselectivity was observed. In this case, 1-aralkyl-3-aminopiperidin-4-oIs were derived as main products from the cleavage of the epoxy C-O bond at position 3. Following these protocols the aminoalcohol products were obtained as pure compounds by simple work-up without the need of chromatographic
separation.
In summary, we present an efficient method for the preparation of 3-amino-4-hydroxypiperidines and its regioisomers in 4-steps. The highly VAChT affine 4-fluorobenzyltrozamicol was obtained in an overall yield of 35%.]]></dc:description>

<dc:title><![CDATA[The impact of hypoxia on gene expression and protein synthesis of Eph receptors and ephrin ligands in human melanoma cells]]></dc:title>
<dc:source><![CDATA[European Journal of Cancer 8(2010), 119]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background 
The transmembrane Eph receptors (Eph) and their ephrin ligands represent the largest subfamily of receptor tyrosine kinases. Eph/ephrins are key players in cell-cell communication due to their capability of bidirectional signaling. There is evidence that Eph/ephrins also play an important role in tumor progression and metastasis. Since hypoxia is an important elicitor for metastatic behaviour of tumor cells, the aim of our study was to investigate the influence of hypoxia on Eph and ephrin expression in primary and metastatic melanoma cell lines.

Materials and methods 
The influence of experimental hypoxia (6 to 72 h) on viability and metabolism of three melanoma cell lines (Mel-Juso, A375, and A2058) was characterized using MTT tests and cellular uptake of both <SUP>18</SUP>F-fluoromisonidazole (FMISO) and <SUP>18</SUP>F-fluorodeoxyglucose (FDG). The mRNA expression of EphA2, EphB4, ephrinA1 and ephrinB2 was analyzed with quantitative RT-PCR. Protein synthesis was determined by flow cytometry. 

Results 
The uptake of FMISO increased in all three melanoma cell lines after incubation under hypoxic conditions. The FDG uptake under hypoxic conditions decreased in all three cell lines. The MTT test demonstrated that viability of A375 cells decreased to 29±3% after 72 h of hypoxia. A2058 cells showed only a weak decrease of viability by approximately 30%, whereas viability of Mel-Juso cells under hypoxia was not influenced. In all cells Eph/ephrin gene expression under hypoxic and normoxic conditions showed only minor differences, except for EphA2 expression in A375 cells, which increased by >40% after 12 h hypoxia. Flow cytometry showed no alteration in ephrin ligands under hypoxic conditions. In contrast, after 72 h hypoxia we detected a slight increase in EphB4 protein in all melanoma cell lines, and enhanced EphA2 protein only in metastatic cell lines A375 and A2058. 

Conclusion
The metastatic melanoma cell lines A375 and A2058 react more sensitive to hypoxic conditions than the primary melanoma cell line Mel-Juso. Experimental hypoxia increases Eph receptor gene expression and protein synthesis, particularly, in metastatic melanoma cell lines, which could be indicative for a further mechanism by which hypoxia affects tumor metastasis.]]></dc:description>

<dc:description><![CDATA[We present new experimental results concerning the azimuthal distributions of proton-likes, light and intermediate mass fragments at midrapidity for Au(100-800 A MeV)+Au collisions measured with the FOPI phase-I detector at GSI in Darmstadt. The azimuthal distributions are investigated as a function of the collision centrality, the incident energy, the fragment charge and transverse momentum. The azimuthal anisotropy is maximum for impact parameters around 7 fm. Intermediate mass fragments present a stronger out-of-plane emission signal than light fragments and a saturation is reached for Z 4. The azimuthal anisotropy increases with the fragment transverse momentum and decreases as the incident energy increases. The azimuthal anisotropy of Z = 2 particles investigated as a function of the scaled fragment transverse momentum follows an universal curve for bombarding energies between 250-800 A MeV. A signature for a transition from in-plane to out-of-plane emission is evidenced at the lowest beam energies.]]></dc:description>

<dc:description><![CDATA[Using the FOPI facility at GSI, charged particles (1\leqZ\leq6) produced in the Au(150 A MeV)+Au reaction have been measured at laboratory angles 1.20<lab<300. Highly central collisions have been selected with two criteria, both dealing with the longitudinal and transverse degrees of freedom of the reaction. The relevance of this selection method is supported by QMD calculations which indicate that such criteria are able to select mean impact parameters less than 2 fm. Bias effects introduced by the criteria have been evaluated. The centre-of-mass polar angle distributions of low energy clusters emitted in
these central collisions, have been extracted: the intensity ratio deduced for a transverse to longitudinal emission is found to be R=1.4+0.2-0.4. Model comparisons using QMD are presented. The value of R appears to depend sensitively on the nucleon-nucleon cross section, nn. Within this model, a value of nn=25±5 mb is derived.

<dc:description><![CDATA[The sorption of selenium(VI) onto pure anatase, a polymorph of titanium dioxide, was investigated. At the macroscopic level, batch experiments and electrophoretic mobility measurements have been performed. Selenium(VI) retention was found to be pH-dependent, i.e. sorption of selenium(VI) decreases with increasing pH (pH range 3.5-11). Selenium(VI) sorption dependence on the ionic strength was also evidenced, i.e. sorption increases while the ionic strength decreases. Electrophoretic mobility measurements showed that selenium(VI) sorption had no effect on the isoelectric point of anatase. At the microscopic level, XPS (X-ray Photoelectron Spectroscopy) measurements evidenced the absence of reduction of selenium(VI) during the sorption process. Furthermore, the nature of the sorbed surface species at the anatase/liquid interface has been elucidated using Attenuated Total Reflection Fourier-Transform Infrared (ATR FT-IR) spectroscopy. The spectroscopic results strongly suggest the formation of outer-sphere complexes on the whole pH range, which is in agreement with batch sorption experiments and electrophoretic mobility findings.]]></dc:description>

<dc:description><![CDATA['3+1' Oxorhenium(v) complexes [ReO(SN(R')S)(SR)] (R' = Me, Et, Pr or Bu; SR = aminoalkane thiolate) have been synthesized by ligand exchange at trans-trichloromonooxo-bis(triphenylphosphine)rhenium(v) with a mixture of HSN(R')SH and RSH in alkaline methanolic solution. The complexes were purified by column chromatography  and characterized by elemental analysis, mass and IR spectroscopy and for selected compounds by <SUP>1</SUP>H NMR spectroscopy. The structures of those complexes have been determined by X-ray diffraction analysis and revealed a change in the co-ordination geometry from square pyramidal to trigonal bipyramidal, depending on the chelating (SN(R')S) moiety. The alkyl group (R') was found to be arranged "syn" to the oxorhenium group. ]]></dc:description>

<dc:description><![CDATA[Plants may take up uranium from contaminated sites and thus may represent a potential risk. To evaluate the risk of uranium being transferred from the environment into the human food chain knowledge concerning the uranium speciation is essential since reactivity and toxicity of uranium largely depend on its speciation. 
Plants take up their nutrients from the soil in dissolved form and thus uranium may enter plants as dissolved species. To study this process the speciation of uranium in a uranium contaminated site, i.e. Gessenheap near Ronneburg in Saxony/Germany was studied by time-resolved laser-induced fluorescence spectroscopy (TRLFS) in the aqueous phase, i.e. in surface water (drainage channel on the Gessenheap) and in pore water (approximately 0.5  1 m below surface of test site Gessenwiese). In both waters uranium sulfate species dominate the uranium speciation and clearly show that uranium sulfate species are in contact with plant components.
In a second step we determined the uranium concentration in the plants obtained from the test field Gessenheap by ICP-MS. For these analyses cell saps of birch leaves, of a birch boletus, and of compartments of butterbur (leaves, roots, and sprouts) were obtained by ultra centrifugation. The highest uranium concentration was found in sap samples from roots of butterbur with 39.3 ppb uranium (approximately 1.5  10-7 M uranium); in the sap samples of birch leaves 18.1 and 16.6 ppb uranium, respectively were detected. In all other sap samples the uranium contents were below 4 ppb uranium. The uranium content in the studied dried plant materials were less than 2.2 ppb, and dried birch leaves contains less than 0.1 ppb uranium. 
The above listed uranium concentrations turned out to be too low to be successfully analyzed by TRLFS. In addition, we have to mention that plant sap may contain substances which quench the fluorescence signal of uranium (VI), e. g. some heavy metal ions or organic compounds. For future studies plant samples containing higher uranium concentrations are used for TRLFS investigations, possibly mosses or lichens.]]></dc:description>

<dc:description><![CDATA[Pt films on alumina substrates, both in their as-received and annealed states, have been extensively characterized by slow positron implantation spectroscopy (SPIS). Bulk Pt samples have been investigated by conventional positron annihilation spectroscopy (PAS) as well as by SPIS. A variety of state-of-the-art theoretical calculations have been performed to aid the interpretation of experimental findings. The research shows that a re-interpretation of earlier defect studies of bulk Pt by PAS is required in order to achieve a satisfactory agreement with the present experimental findings and theory.]]></dc:description>

<dc:description><![CDATA[Surface modification of titanium is of interest considering the necessary improvement of mechanical properties of this material for
applications as e.g. artificial joints. This work is devoted to the formation of a layer with a high content of the titanium aluminides Ti3Al
and TiAl below the surface by high-dose aluminium implantation. If the maximum aluminium concentration exceeds 20 at.%,
precipitation of Ti3Al is detected by XRD already in the as-implanted state. For maximum aluminium concentrations between 50 and 55
at.%, the phase TiAl is found beside Ti3Al after annealing at 700°C. For a double implantation resulting in an aluminium concentration of
about 60 at.% in the depth range between 100 and 200 nm, a disordered fcc TiAl phase is observed after implantation as precursor for
the ordered tetragonal TiAl formed by subsequent annealing at 600°C.]]></dc:description>

<dc:description><![CDATA[The strong influence of dose rate and implantation temperature on the dose dependence of the shape of Ge channeling implantation profiles is demonstrated for the first time. Applying a focused ion beam (FIB) system allows the use of a very high (10<SUP>18</SUP> cm<SUP>-2</SUP>s<SUP>-1</SUP>) and a very low (10<SUP>10</SUP>-10<SUP>11</SUP> cm<SUP>-2</SUP>s<SUP>-1</SUP>) dose rate. Implantations are performed at R.T. and at 250°C. At the high dose rate and R.T. the dose rate dependence of the profile shape is found to be most pronounced. Atomistic computer simulations using a relatively simple damage buildup model can explain the effects observed. It is shown that at R.T. defect relaxation processes can last up to 1 s, which is longer than assumed so far. The lifetime of implantation defects at 250°C is estimated to be in the  order of 10s.]]></dc:description>

<dc:title><![CDATA[The effect of rare-earth clustering on charge trapping and electroluminescence in rare-earth implanted metal-oxide-semiconductor light-emitting devices]]></dc:title>
<dc:source><![CDATA[Journal of Applied Physics 107(2010)12, 123112]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The effect of rare-earth clustering in dielectric media on the electroluminescence (EL) intensity, the charge trapping and the EL quenching was investigated using the example of Tb and Eu-implanted SiO<sub>2</sub> layers. It was shown that the increase in the REO<sub>X</sub> cluster size induced by an increase in the furnace annealing temperature resulted in an increase in the concentration of electron traps with capture cross sections from 2 x 10<sup>-15</sup> to 2 x 10<sup>-18</sup> cm<sup>2</sup>. This is probably associated with an increase in the concentration of oxygen deficiency centers as well as with strained and dangling bonds in the SiO<sub>2</sub> matrix which leads to an enhanced scattering of hot electrons and a decrease in the excitation cross section of the main EL lines of RE<sup>3+</sup> ions. For the main EL lines of Tb<sup>3+</sup> and Eu<sup>3+</sup> ions the relation of the EL quenching to negative and positive charge generation in the SiO<sub>2</sub> was considered. It was demonstrated that in case of REO<sub>X</sub> nanoclusters with small sizes (up to 5 nm) the E!
 L quenching process can mainly be explained by a defect shell model which suggests the formation of negatively charged defect shells around the nanoclusters leading to a Coulomb repulsion of hot electrons and a suppression of the RE<sup>3+</sup> excitation. At high levels of the injected charge (more than 2 x 10<sup>20</sup> e/cm<sup>2</sup>) a second stage of the EL quenching was observed which was contributed to a positive charge accumulation in the SiO<sub>2</sub> at a distance beyond the tunneling distance from the SiO<sub>2</sub>-Si interface. In case of Eu-implanted SiO<sub>2</sub> the quenching of the main EL line of Eu<sup>3+</sup> is mostly correlated with positive charge trapping in the bulk of the dielectric. A model of EL quenching of the main Eu<sup>3+</sup> line is proposed. (C) 2010 American Institute of Physics.]]></dc:description>

<dc:description><![CDATA[Phase resolved X-ray Ferromagnetic Resonance (XFMR) has been measured in fluorescence yield, widening the application of XFMR to opaque samples on opaque substrates. Magnetization dynamics were excited in a Co<sub>50</sub>Fe<sub>50</sub>(0.7)/Ni<sub>90</sub>Fe<sub>10</sub>(5) bilayer by means of a continuous wave  microwave excitation, while X-ray Magnetic Circular Dichroism (XMCD) spectra were measured stroboscopically at different points in the precession cycle. By tuning the x-ray energy to the L3 edge of Ni or Fe, the dependence of the real and imaginary components of the magnetic susceptibility upon the strength of an externally applied static was determined. First results from measurements on a Co<sub>50</sub>Fe<sub>50</sub>(0.7)/Ni<sub>90</sub>Fe<sub>10</sub>(5)/Dy(1) sample confirm that enhanced damping results from the addition of the Dy cap.]]></dc:description>

<dc:description><![CDATA['3+1' Mixed-ligand [<SUP>99m</SUP>Tc]oxotechnetium complexes with affinity for melanoma were synthesized in a one-pot reaction. Complexation of technetium-99m with a mixture of N-R(3-azapentane-1,5-dithiol) [R = Me, Pr, Bn, Et<SUB>2</SUB>N(CH<SUB>2</SUB>)<SUB>2</SUB>] and N-(2-dialkylamino)ethanethiol [alkyl] = X = Et, Bu, morpholinyl] using Sn<SUP>2+</SUP> as the reducing agent resulted in the formation of '3+1' mixed-ligand technetium-99m complexes [TcO(SN(R)S)(SNX<SUB>2</SUB>)] in high radiochemical yield (60-98%). In vitro uptake studies in B16 murine melanoma cells indicated a moderate tumor-cell accumulation (40%) of compound 1 [R = Me, X = Et] and a higher accumulation (69%) of compound 2 [R = Me, X = Bu] after a 60-min incubation. In vivo evaluation of compounds 1-6 in the C57B16/B16 mouse melanoma model demonstrated tumor localization. Compound 2 displayed the highest accumulation with up to 5% ID/g at 60 min after injection. In vivo, 2 also showed a low blood-pool activity and high melanoma/spleen (4.3) and melanoma/lung (1.9) ratios at 1 h. These results suggest that small technetium-99m complexes could be useful as potential melanoma-imaging agents. ]]></dc:description>

<dc:description><![CDATA[The type of monitoring of nuclear power plants in Ukraine practised early nineties provided the supervisory authority with only inadequate access to information about the current safety status of plants. For the Zaporozhye NPP, unit 5, a technical system to improve the operational monitoring has been designed, installed and commissioned for trial operation at the end of 1995 as a pilot project. The system complements existing operation checking and monitoring facilities by including modern means of information technology. It enables concentration on a continuous monitoring of the state of unit 5 in normal operation and in cases of anomalies or incidents so that when recognisable deviations from the regular plant operation occur, the authority can immediately inquire and if necessary impose conditions on the operator. In 1997 the Information and Crisis Centre of the Ukraine supervisory authority in Kiev has equipped with the most essential technical means necessary for quasi-simultaneous transfer of data and voice and for monitoring purposes and connected the Centre to the Zaporozhye system. A similar monitoring system for both VVER-440 units of the Rovno NPP by analogy with the pilot project was specified, put into operation and connected to the ICC in 1998.]]></dc:description>

<dc:title><![CDATA[Tilting of self-organized layered arrays of encapsulated metal nanoparticles in C:Ni nanocomposite films by means of hyperthermal ion deposition]]></dc:title>
<dc:source><![CDATA[ICMCTF 2010 38th International Conference on Metallurgical Coatings & Thin Films, 02.-06.05.2010, San Diego, California, United States of America]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Self-organization at the nanoscale is a key issue in modern material science as it promises a potential route to commercially scalable production of functional nanomaterials. Here we present the growth-structure study of self-organized layered arrays of carbon encapsulated Ni nanoparticles grown by means of pulsed filtered cathodic vacuum arc deposition. Influence of the oblique ion incidence and Ni content on the film morphology is investigated. The film morphology has been determined by transmission electron microscopy (TEM) and grazing incidence small angle x-ray scattering (GISAXS) while C/Ni ratio was determined by means of nuclear reaction analysis. The C:Ni films with the Ni content in the range of ~6-50 at.% are considered. The results show that for the perpendicular incoming depositing ion incidence the C:Ni film structure consists of alternating self-organized nickel carbide and carbon layer oriented parallel to the film surface. However, for the oblique ion incidence the layered structure tilts in relation to the surface. The tilting angle and periodicity strongly depends on the deposition angle as well as on the Ni content. Combined TEM and GISAXS analysis shows that the film cross-sections can be described by two density modulation waves advancing with the growing film surface  one towards the incoming ions, another one with the weaker amplitude moving in roughly perpendicular direction. The results are discussed on the basis of the interplay between thermodynamically driven phase separation and energetic ion induced ballistic effects. Such structures show significant anisotropy which can be considered for tribological, optical, magnetic or magnetotransport applications.]]></dc:description>

<dc:source><![CDATA[Journal of Oncology 2010(2010), 135285]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Eph receptors and their ephrin ligands were identified in the late 1980's. Subsequently, they were linked to different physiological and pathophysiological processes like embryonic development, angiogenesis, and tumorigenesis. In this regard, recent work focused on the distribution and effects of Eph receptors and ephrins on tumor cells and tumor microenvironment. The purpose of this review is to outline the role of these molecules in physiological angiogenesis and pathophysiological tumor angiogenesis. Furthermore, novel therapeutical approaches are discussed as Eph receptors and ephrins represent attractive targets for antiangiogenic therapy.]]></dc:description>

<dc:description><![CDATA[Extended duality (i.e. the replacement of the thermal dilepton emissivity of hadron matter by that of q bar q annihilation) 
is used to explain the dilepton data of heavy-ion experiments at CERN-SPS. Taking into account the background contributions (hadronic cocktail, Drell-Yan, semileptonic open charm decays) the spectral shapes of the CERES, NA38/50 and HELIOS-3 data in experiments with lead and sulfur beams can be well described while the normalizations of the sulfur beam data is problematic.]]></dc:description>

<dc:title><![CDATA[Modeling of Condensation in Horizontal Tubes]]></dc:title>
<dc:source><![CDATA[Nuclear Engineering and Design 204 Issue 1-3 (2001) 251-265]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[The condensation in horizontal tubes plays an important role e.g. for the determination of the operation mode of horizontal steam generators of VVER reactors or passive safety systems for the next generation of nuclear power plants. Two different approaches (HOTKON and KONWAR) for modeling this process have been undertaken by Forschungszentrum Jülich (FZJ) and University for Applied Sciences Zittau/Görlitz (HTWS) and implemented into the 1D-thermohydraulic code ATHLET, which is developed by the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS) mbH for the analysis of anticipated and abnormal transients in light water reactors. 
Although the improvements of the condensation models are developed for different applications (VVER steam generators - emergency condenser of the SWR1000) with strongly different operation conditions (e.g. the temperature difference over the tube wall in HORUS is up to 30 K and in NOKO up to 250 K, the heat flux density in HORUS is up to 40 kW/m² and in NOKO up to 1 GW/m²) both models are now compared and assessed by Forschungszentrum Rossendorf FZR e.V. Therefore post test calculations of four selected HORUS experiments were performed with ATHLET/KONWAR. It can be seen that the calculations with the extension KONWAR as well as HOTKON improve significantly the agreement between computational and experimental data. ]]></dc:description>

<dc:source><![CDATA[Physica Scripta T94 (2001) 98-101]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[Tritium depth profiling measurements by accelerator mass spectrometry  have been performed at the facility installed at the Rossendorf  3 MV Tandetron. In order to achieve an  uniform erosion at the target surface inside of a commercial Cs ion sputtering source and to avoid edge effects, the samples were mechanically scanned inside of a commercial Cs sputter ion source. The sputtered negative ions were mass analysed by the injection magnet of the Tandetron. Interesting ions except tritium are measured with the Faraday cup between the injection magnet and the accelerator, while the tritium is counted after the accelerator with semiconductor detectors. Depth profiles have been measured for carbon samples which had been exposed to the plasma at the first wall of the Garching fusion experiment ASDEX-Upgrade and from the European fusion experiment JET, Culham/UK. Tritium contents in the JET samples were up to six orders higher than in samples from ASDEX-Upgrade. Tritium beam currents from samples with high tritium content can be measured partly in the Faraday cup before the accelerator. A dedicated tritium AMS facility with an air-insulated 100 kV tandem accelerator is under construction. First results of test operation are presented.]]></dc:description>

<dc:description><![CDATA[The design of a sputter deposition chamber for the in situ study of film growth by synchrotron x-ray diffraction and reflectivity is reported. Four x-ray windows, sealed with low cost, non-hazardous Kapton, enable scattering both in the horizontal as well as in the vertical scattering planes. The chamber fits into a standard six-circle goniometer from Huber which is relatively widespread in synchrotron laboratories. Two miniature magnetrons and additional gas inlets allow for the deposition of compound films or multilayers. Substrate heating up to 650°C and different substrate bias voltage are possible. The performance of the chamber was tested with the deposition of high quality TiN films of different thicknesses. ]]></dc:description>

<dc:date>2000</dc:date>
<dc:description><![CDATA[Different SiC-surfaces were coated with thin layers of Si or Ge and subsequently annealed to 900 °C respective 600 °C. According to AFM results, Si- or Ge-clusters, respectively, are formed whose number, size distribution and shape depend on the process parameters. Such samples were investigated with synchrotron x-ray diffraction on the ROBL-beamline at the ESRF. The /2 - scans show for all samples (111)- and (220)-reflections of Si or Ge, respectively. This reveals unambiguously that the clusters grow preferentially in two different orientations (<111>, <110>). Interestingly, for the Ge-samples those reflections are shifted towards the angular position of the corresponding Si-reflection. Such a peak shift could be explained by a lattice distortion due to the lattice mismatch or by the change in the lattice constant due to the formation of a Si/Ge solid solution. The lateral orientation of the (111)- and (110)-clusters was investigated by comparison of the -scans of a cluster-reflection (220-reflection for (111)-clusters and 111-reflection for (110)-clusters) with an appropriate substrate-reflection. This comparison showed that the (111)-clusters as well as the (110)-clusters grow coherently with respect to the substrate. ]]></dc:description>

<dc:date>2002</dc:date>
<dc:description><![CDATA[Particle Induced X-ray Emission (PIXE) at the external proton beam has proved ideal to study the individual techniques used for creating art objects. In particular, PIXE is tailored for examining paintings because of the low level of background produced by organic components like binders and paper backings. Thus, even traces of pigments as deposited by pens on cardboard can be identified by this method. The combination of PIXE with external Rutherford Backscattering Spectrometry (RBS) allows non-destructive gain of knowledge on near-surface and thin film arrangements of paint materials. Thicker but less complex layers of oil paintings can be identified by special procedures of depth resolved PIXE investigation. In this case, RBS provides additional information on organic coverings like madder lake or varnishes. ]]></dc:description>

<dc:title><![CDATA[18F-Labelled Alkyl-Substituted Spirocyclic Piperidines – Potential Radiotracers For PET Imaging Of σ1 Receptors]]></dc:title>
<dc:source><![CDATA[BRAIN 2011, 24.-28.05.2011, Barcelona, Spain]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[Objectives: Neuroprotective effects mediated by signal transduction via the transmembrane σ1 receptor localised in the endoplasmatic reticulum make this receptor a promising target for novel approaches in the therapy of neurodegenerative diseases. Furthermore, behavioural changes are assumed to be related to alterations in the expression of σ1 receptors mainly expressed in the striatum. Thus, molecular imaging of σ1 receptors of the brain may hold potential in diagnostics and drug development, and we have compared in mice radiotracer properties of a series of new 18F-labelled spirocyclic piperidine derivatives with high affinity and selectivity for σ1 receptors. 

Methods: Radiosynthesis of fluoromethyl- ([18F]WMS1850), fluoroethyl- ([18F]fluspidine), fluoropropyl- ([18F]WMS1813), and fluorobutyl-([18F]WMS1847) substituted derivatives was performed by nucleophilic substitution of the corresponding tosylate precursors using  K[18F]F-K222-carbonate complex. Organ distribution of radiotracers applied i.v. was determined in female CD-1 mice at 5, 30, 60, and 120 min p.i. Spatial distribution of the radiotracer binding sites was examined by ex vivo brain autoradiography at 45 min p.i. Target specificity was investigated in blocking studies with pre-application of 1 mg/kg of the σ1 receptor ligand haloperidol by assessing the organ distribution of the respective radiotracer at 60 min p.i. The metabolic stability in vivo of each radiotracer was evaluated by radio-TLC and -HPLC analyses of brain, plasma, and urine samples. 

Results: The radiotracers were obtained with radiochemical yields of 35-53%, radiochemical purities >98.5%, and specific activities >150 GBq/µmol. All radiotracers readily passed the blood-brain barrier with high brain uptake values at 30 min p.i.:  [18F]fluspidine = 4.71 ± 1.39 % ID/g, [18F]WMS1813 = 3.18 ± 0.68 % ID/g, [18F]WMS1850 = 2.65 ± 0.68 %ID/g, and [18F]WMS1847 = 1.78 ± 0.16 %ID/g. High initial radioactivity uptake was also observed in peripheral organs which express σ1 receptors such as spleen, thymus, kidney, and stomach. In brain as well as in these organs the uptake of radioactivity  was significantly reduced in mice pre-treated with haloperidol. Distribution patterns of the radiotracer binding sites in brain were resembling for all four radiotracers with [18F]fluspidine possessing the highest target (facial nucleus)-to-nontarget (olfactory bulb) ratio (4.69 at 45 min p.i.). The metabolic stability in vivo was high for all radiotracers (75% parent radiotracer in plasma at 30 min p.i.), and none of the peripherally detected radiometabolites crossed the blood-brain barrier. 

Conclusion: Fluoroalkylated spirocyclic piperidines are high affinity ligands for σ1 receptors with high brain uptake, specific binding, and good metabolic stability. Within the herein reported series of 18F-labelled derivatives, the in vivo data identify [18F]fluspidine as the most suitable radiotracer for further development in molecular imaging of σ1 receptors. [18F]fluspidine radiosynthesis is selected for transfer to an automated radiosynthesis module for further preclinical development.]]></dc:description>

<dc:description><![CDATA[We report the synthesis and evaluation of 1'-(4-[125I]iodobenzyl)-3H-spiro[isobenzofuran-1,4'-piperidine] ([125I]Spiro-I) as a potential SPECT tracer for imaging of σ1 receptors. [125I]Spiro-I was prepared in 5565% isolated radiochemical yield, with radiochemical purity of >99%, via iododestannylation of the corresponding tributyltin precursor. In receptor binding studies, Spiro-I displayed low nanomolar affinity for σ1 receptors (σ1: Ki = 2.75 ± 0.12 nM; σ2: Ki = 340 nM) and high subtype selectivity (σ2/σ1 = 124). Biodistribution in mice demonstrated relatively high concentration of radioactivity in organs known to contain σ1 receptors, including the lung, kidney, heart, spleen, and brain. Administration of haloperidol 5 min prior to injection of [125I]Spiro-I significantly reduced the concentration of radioactivity in the above-mentioned organs. These findings suggest that the binding of [125I]Spiro-I to σ1 receptors in vivo is specific.]]></dc:description>

<dc:description><![CDATA[An overview of the activity on metal oxides grown by reactive pulsed magnetron sputtering (RPMS) is presented, including high refractive index materials (Nb2O5) and transparent conductive oxides (Sn-doped In2O3 and Al-doped ZnO). For Nb2O5 the influence of process parameters such as plasma density and substrate temperature on optical properties, their thermal stability and film microstructure are discussed. In case of Sn-doped In2O3 (ITO) it is shown that by isothermal or electric current annealing amorphous films crystallize at different activation energies and that the resistivity decreases in two steps ascribed to relaxation and Sn donor activation. Finally it is shown that by RPMS films of Al-doped ZnO (AZO) with high mobility (45 cm²/Vs) can be obtained. The existence and dependence of an optimum substrate temperature for maximum mobility is discussed. Furthermore it is shown that in polycrystalline AZO the carrier mobility is limited by a combination of ionized impurity scattering and grain boundary limited transport depending on the carrier concentration. These effects are also influenced by the Al concentration in the sputtering target.]]></dc:description>

<dc:title><![CDATA[Manganese doped Germanium: from clustering to carrier-mediated ferromagnetism]]></dc:title>
<dc:source><![CDATA[International Conference on Physics and Applications of Spin Related Phenomena in Semiconductors (PASPS-VI), 01.-04.08.2010, Tokyo, Japan]]></dc:source>

<dc:description><![CDATA[Manganese doped Germanium (Ge:Mn) is a promising candidate for a ferromagnetic semiconductor compatible with silicon technology, since Mn acts as a magnetic ion as well as a double acceptor. In recent years, Ge:Mn thin layers as well as nanostructures have been fabricated, mostly by LT-MBE, and analyzed [1-4]. Whereas ferromagnetism above room temperature has been evidenced by magnetization measurements, the transport behavior (magnetoresistance: MR, anomalous Hall effect: AHE) is entirely different from the GaAs:Mn system, the prototype of a ferromagnetic semiconductor. For instance, the previously reported AHE in Ge:Mn (i) was observed at temperatures above 10 K, (ii) but exhibited no hysteresis, and (iii) changed the sign of its slope. This behavior has been ascribed to Mn-diluted Ge [2, 4], Mn-rich spinodal decomposed phases [3] and MnGe precipitates [5], respectively. We argue that the origin of these observations lies in the less effective substitution of Mn at Ge sites, which results in too low a hole concentration, making carrier-mediated ferromagnetism impossible. The hole concentrations realized in Ge:Mn grown by LT-MBE are mostly well below 10<sup>19</sup> cm<sup>-3</sup>.

We have prepared a series of Ge:Mn layer by Mn ion implantation into near-intrinsic, n-type Ge substrates, at 350 °C (resulting in Mn5Ge3 clusters) and -40 °C (without precipitates) [6-8]. The Mn concentration ranges from 0.004% to 10%. For samples with 10% Mn, several annealing procedures have been applied, namely ms flash lamp annealing and nsec pulsed laser annealing with various optical fluences. By this systematic preparation, we obtained three kinds of samples: (1) very dilute Ge:Mn where no ferromagnetic coupling can be expected [6]; (2) nanocrystalline Mn5Ge3 embedded inside the Ge matrix [7]; and (3) diluted Ge:Mn together with Mn-rich spinodal phases [8]. Indeed all samples show p-type conductivity with a hole concentration ranging from 10<sup>18</sup> to 10<sup>20</sup> cm<sup>-3</sup>. The highest concentrations above 1020 cm<sup>-3</sup> can only be achieved with the help of pulsed laser annealing. A careful characterization of structure, magnetic and transport properties, leads us to the following conclusions.

(1) From 20 to 10 K the resistance of samples with a hole concentration of >10<sup>18</sup> cm<sup>-3</sup> increases in an activated manner with an activation energy of 4 meV, but below 10 K it saturates, i.e. the sample behaves metallic. 
(2) We evoke the consideration of a two-band-like conduction in Ge:Mn. Above 10 K another conducting channel with different mobility is active, resulting in the drop of resistivity and the anomalous Hall resistance. The latter can be well described over a wide of parameters by considering two types of carriers with different mobility and population (see Ref. 6).
(3) In the sample with the largest hole concentration of 2×10<sup>20</sup> cm<sup>-3</sup>, we observed, for the first time to our knowledge, a one-to-one correspondence between the hysteresis in magnetization, magnetoresistance and Hall resistance below 10 K. This is our key result, shown in Fig. 1, and is a strong evidence for carrier-mediated ferromagnetism. Note however that considering mere magnetization data, ferromagnetism remains present up to >100 K.   

In summary, we present the magnetic and magnetotransport properties of a series of Ge:Mn samples with hole concentrations ranging from 10<sup>18</sup> to 2x10<sup>20</sup> cm<sup>-3</sup>. The hole concentration is the critical parameter to establish carrier mediated ferromagnetism in Ge:Mn, similar as is known for GaAs:Mn. A high-concentration co-doping with a shallow acceptor may allow to increase the hole concentration further, possibly resulting in a dramatically increased Curie temperature. In addition to the compatibility to Si technology, ion implantation followed by pulsed laser annealing is an established scalable chip technology and therefore may have a significant industry impact.

<dc:title><![CDATA[Hot Electrons Transverse Refluxing in Ultraintense Laser-Solid Interactions]]></dc:title>
<dc:source><![CDATA[Physical Review Letters 105(2010), 015005]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[We have analyzed the coupling of ultraintense lasers (at ∼2×1019   W/cm<sup>2</sup>) with solid foils of limited transverse extent (∼10  s of μm) by monitoring the electrons and ions emitted from the target. We observe that reducing the target surface area allows electrons at the target surface to be reflected from the target edges during or shortly after the laser pulse. This transverse refluxing can maintain a hotter, denser and more homogeneous electron sheath around the target for a longer time. Consequently, when transverse refluxing takes places within the acceleration time of associated ions, we observe increased maximum proton energies (up to threefold), increased laser-to-ion conversion efficiency (up to a factor 30), and reduced divergence which bodes well for a number of applications.]]></dc:description>

<dc:description><![CDATA[Aluminum (oxy)hydroxide films play an important role as sorbents of toxic elements in aqueous environments, where their heterogeneous nucleation and growth can be controlled by the speciation of dissolved Al species and the charge and structure of underlying mineral surfaces. The structure of gibbsite films nucleated at the interface between the muscovite (001) surface and 1 mM AlCl3 solutions was investigated as a function of pH using in situ X-ray reflectivity. Growth of well-ordered gibbsite films was observed at pH 3–4, even when the solutions were undersaturated with respect to gibbsite. The ordering of these gibbsite films likely resulted from the structural similarity (i.e., epitaxy) between the basal planes of gibbsite and muscovite. In contrast, no film growth was observed at pH 9–12 where the solutions were supersaturated with respect to gibbsite. These results indicate that adsorption and accumulation of aqueous Al(III) species (i.e., Al3+ and AlOH2+ at acidic pH) is a critical step for the formation of secondary minerals on the negatively-charged muscovite surface.]]></dc:description>

<dc:title><![CDATA[Identification of the uranium speciation in an underground acid mine drainage environment analysed by laser fluorescence spectroscopy]]></dc:title>
<dc:source><![CDATA[Geochimica et Cosmochimica Acta 75(2011), 2200-2212]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[The subsurface acid mine drainage (AMD) environment of an abandoned underground uranium mine in Königstein/Saxony/Germany, currently in the process of remediation, is characterized by low pH, high sulfate concentrations and elevated concentrations of heavy metals, in particular uranium. Acid streamers thrive in the mine drainage channels and are heavily coated with iron precipitates identified as schwertmannite and jarosite. These precipitates are biomineralisations and related to the presence of Fe-oxidizing microorganisms. Such precipitates were also observed in stalactite-like dripstone, called snottites, growing on the gallery ceilings. The bacterial diversity was identified on basis of analysed 16S rDNA sequences and revealed that the beta-proteobacterium Ferrovum myxofaciens dominates. Colloidal uranium, neither as U(IV)- or as U(VI) eigencolloids nor uranium adsorbed on colloids was detected as photon correlation spectroscopy analyses and centrifugation experiments of drainage water and snottite water at different centrifugal accelerations between 500 g and 46000 g showed.
The uranium speciation in the underground AMD waters flowing in mine galleries as well as dripping from the ceiling and forming stalactite-like dripstones were studied by time resolved laser-induced fluorescence spectroscopy (TRLFS). The fluorescence lifetime of both waters were best described with a mono-exponential decay, indicating the presence of one species only. The detected positions of the emission bands and by comparing it in a fingerprinting procedure with spectra obtained for acid sulfate reference solutions, in particular Fe - SO42- - UO22+ reference solutions, indicated that the uranium speciation in the AMD environment of Königstein is dominated in the pH range of 2.5 to 3.0 by the highly mobile aquatic uranium sulfate species UO2SO4(aq) and formation of uranium precipitates is rather unlikely as is retardation by sorption processes. The presence of iron in the AMD reduces the fluorescence lifetime of the UO2SO4(aq) species from 4.3 µs found in iron-free uranium sulfate reference solutions to 0.7 µs in both AMD waters of Königstein and in iron containing uranium sulfate reference solutions, respectively. Thermodynamic calculations indicated the presence of two additional uranium species, i.e. UO2(SO4)2- and UO22+ in AMD of Königstein, however TRLFS provided no spectroscopic evidence for their existence. 
TRLFS was directly applied to complex solutions of acid mine drainage (AMD) environments intimately associated with microbiology and Fe-precipitates and shows that it is a suitable spectroscopic technique to identify the uranium speciation in natural solutions containing a multitude of different complexing agents.]]></dc:description>

<dc:description><![CDATA[Carbon implantations into silicon were carried out in order to form thin surface layers of SiC. Single crystalline <100> silicon samples were implanted with 40 keV 13C ions with a fluence of 3.8x1017 ions/cm2 and subsequently thermally treated under high vacuum conditions at different temperatures using a 20 keV electron beam. The isotope 13C offers the advantage to measure the carbon redistribution caused by the thermal treatment process with the nuclear resonance reaction analysis. The crystallinity of the SiC surface layers is studied by X-ray diffraction and transmission electron microscopy measurements. A polycrystalline 3C-SiC surface layer with a low content of 6H-SiC grains is formed with a thickness of about 70 nm. The analysis of high resolution TEM micrographs from the interface region shows obviously that the 6H-SiC phase coexists with the 3C-SiC modification in SiC layer.

<dc:description><![CDATA[Magnetic properties of a presurface zone of the bulk, single-crystal (110)Cr, implanted with 119Sn ions were studied by means of conversion electron Mössbauer spectroscopy. A strong enhancement of the magnetic hyperfine field, B, was found. The increase is by a factor of ~2.7 in the average value of B and by a factor of ~2.3 in the most probable value of B (the amplitude of the spin-density waves, SDW's). The observed effects are explained in terms of the interference of two spin-density waves having the same amplitude phase but various polarizations. The relative contributions of the interfering SDW's was estimated as equal to ~60% for those with mutual perpendicular and ~40% for those with mutual parallel polarization. ]]></dc:description>

<dc:source><![CDATA[Kerntechnik 66(2001) 195-201]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[The Rossendorf Beamline at the European Synchrotron Radiation Facility is equipped with a unique radiochemistry experimental station. This dedicated station has been designed to perform environmentally relevant experiments on radionuclides, in particular actinides, using synchrotron based X-ray absorption fine structure spectroscopy. The technical concepts and the layout of this experimental station, where radioactive solids and liquids with activities of up to 185 MBq can be studied, are presented. The radiological safety of experimenters, equipment, and of the environment are ensured by the specially developed radiochemistry safety system. The multibarrier concept, the ventilation and air monitoring systems, the radiological protection system, and special software components for recording and visualisation of the safety status are described in detail.

<dc:description><![CDATA[This article describes the crystal selection and quality control utilized to develop and calibrate a high resolution array of CsI(TI) scintillator crystals for the detection of energetic charged particles. Alpha sources are used to test the light output variation due to thallium doping gradients. Selection of crystals with better than 1% non-uniformity in light output is accomplished using this method. Tests with 240 MeV alpha beam reveal that local light output variations within each of the tested CsI(TI) crystals limit the resolution to about 0.5%. Charge and mass dependences in the energy - light output relationship are determined by calibrating with energetic projectile fragmentation beams.]]></dc:description>

<dc:title><![CDATA[Characterization of mesoporous ZnO:SiO<SUB>2</SUB> films obtained by the sol-gel method]]></dc:title>
<dc:source><![CDATA[Thin Solid Films 518(2010), 7002-7006]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[ZnO:SiO<SUB>2</SUB> films are intensively investigated for optical and electronic applications. Additionally, porous ZnO:SiO<SUB>2</SUB> films are of great interest as catalyst and gas-sensing materials. The solgel method is an efficient and low-cost process for the deposition of meso- and microporous silica-based films. The present paper studies the effect of the withdrawal speed on the microstructure and optical properties of mesoporous ZnO:SiO<SUB>2</SUB> films obtained by the solgel method. The morphology of the films was investigated by atomic force microscopy and the overall structure was studied by X-ray diffraction. The structure and size of the zinc oxide nanoparticles embedded in the silica matrix were investigated in more detail by transmission electron microscopy. These techniques showed ZnO:SiO<SUB>2</SUB> films with crack-free mesoporous morphology and highly efficient embedding of ZnO nanoparticles with (100) preferred orientation. Furthermore, the optical transmittance (in the visible and near infrared regions) and the optical band gap value were observed to vary with withdrawal speed. It is shown that ZnO:SiO<SUB>2</SUB> nanocomposites films which possess ZnO particles exhibiting a (100) orientation, with possible special applications in non-linear optics, could be prepared by the low-temperature crystallization solgel method.]]></dc:description>

<dc:description><![CDATA[In high-dose ion implantation nanoclusters can be formed in a rather well-controlled manner as a function of implantation parameters like ion fluence, ion flux and substrate temperature. According to our current understanding of ion beam synthesis the evolution of nanoclusters is determined by the competition between ballistic and thermodynamic effects. While standard thermodynamics, i.e. the phase transition from a supersaturated solid-solution to second-phase precipitates via homogeneous nucleation and growth, gives a reasonable explanation for a variety of observed nanostructures, under irradiation conditions ballistic processes can modify the phase-ordering kinetics dramatically. By incorporating collisional mixing with the standard thermodynamical kinetic Monte-Carlo model, analytical predictions of irradiation effects of nanoclusters, e.g. inverse Ostwald ripening, are discussed.]]></dc:description>

<dc:date>2001</dc:date>
<dc:description><![CDATA[When sub mm size gold inclusions in SiO2 are irradiated with MeV gold ions, a ring of nanometer-size clusters is formed in their immediate vicinity. The size, density and radial distribution of these nanoclusters was determined. Our observations are in agreement with a recent prediction that in a driven system, under appropriate ion beam and temperature conditions, the steady-state solute concentration's dependence on precipitate size may be opposite to that expected from the equilibrium Gibbs-Thomson relation. Kinetic Monte-Carlo simulations account for additional experimental results: the irradiation-induced increase in solute concentration can promote nucleation of additional precipitates around the first ring. The latter finding contradicts the usual assumption that ion beam mixing hinders nucleation.]]></dc:description>

<dc:description><![CDATA[Strahlungsinduzierte Defekte können die Eigenschaften von Festkörpern stark verändern. Die physikalischen Prozesse bei der Bildung und Evolution dieser Defekten laufen auf sehr unterschiedlichen Zeit- und Längenskalen ab und sind dem Experiment nur teilweise direkt zugänglich. Multiskalen-Computersimulationen tragen zum besseren Verständnis der genannten Vorgänge und ihres Einflusses auf die Materialeigenschaften bei. Die atomistische Modellierung spielt dabei eine wichtige Rolle. Im Vortrag wird das am Beispiel der ionenstrahlinduzierten Defektbildung und der Defektmigration in Silicium erläutert. Die methodischen und inhaltlichen Verbindungen zwischen diesen Untersuchungen und der atomistischen Simulation von strahlungsinduzierten Defekten im Reaktorstahl werden aufgezeigt und diskutiert.]]></dc:description>

<dc:description><![CDATA[Atomic calculations, based on empirical potentials and the method of homogeneous deformation, are presented for the elastic properties of as-deposited amorphous carbon at 0 K. Several structural models of amorphous carbon generated by a realistic molecular-dynamics simulation of ion-beam deposition were studied. The models yield intrinsic compressive stresses of approximately 10 GPa. Here, we examine the dependence of the second-order elastic constants of amorphous carbon on the intrinsic stress, as well as on hydrostatic pressure. Different sets of elastic constants describing the behaviour of a solid under stress are considered. The nonlinear effects are shown to become appreciable at a pressure of 10 GPa, whereas the difference between the elastic constants in the equations of motion and the Lagrangian elastic constants is not large. ]]></dc:description>

<dc:source><![CDATA[Thin Solid Films 416 (2002) 114-121]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[Co/Cu multilayers were prepared by cross-beam pulsed laser deposition and characterised by high-angle X-ray diffraction as well as specular and off-specular reflection before and after annealing (500 °C, 2h). Using synchrotron radiation at the K-edge energy of Co and Cu to enhance the scattering contrast, the study shows that annealing does not enlarge the interface roughness but strongly influences the interface morphology. In the fractal model of self-affine structures the latter is expressed by the drastic reduction of the extremely large lateral roughness correlation length parameter from about 4 µm in the as-deposited state to about 20 nm after annealing. High-angle X-ray diffraction indicates that the reduction of lateral roughness correlation length  is caused by grain coarsening due to growth of crystallites and grain boundaries. Thermal treatment enhances the separation of Co and Cu at the interface, i.e. the initially very jagged (roughness exponent between 0.15 and 0.3) structure is smoothed (roughness exponent between 0.6 and 0.7).

<dc:description><![CDATA[Am Beispiel von dotierten Halbleitern konnte gezeigt werden, dass es mit Hilfe der korrekten Interpretation von KPFM-Daten möglich ist, die gemessene KPFM-Spannung mit der Ladungsträger-Konzentration in den untersuchten Halbleitern zu korrelieren. Die präsentierten Ergebnisse an dotiertem Silizium und Mn-implantiertem Germanium legen nahe, dass die Modellierung der KPFM-Spannung auf alle dotierten Halbleitermaterialien angewandt werden kann, solange die intrinsische Ladungsträgerkonzentration geringer als die Dotierkonzentration ist. Wir erwarten, dass in Zukunft die KPFM-Methode auch zur quantitativen Untersuchung der elektrischen Eigenschaften anderer Materialsysteme eingesetzt wird. Grundlage dafür ist immer das Verständnis der Ursache der mittels KPFM detektierten elektrostatischen Kräfte und die damit verbundene korrekte Interpretation der KPFM-Spannung.]]></dc:description>

<dc:source><![CDATA[Materials Science in Semiconductor Processing 3 (2000) 297-301]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[Damage has been observed in MeV-ion-implanted Si away from the maximum of the nuclear energy deposition profile, mainly around the half of the projected ion range, Rp/2, after annealing at temperatures between 700°C ad 1000°C. This damage is primarily created by the implanted ions and consists of intrinsic defects remaining so small that they have not been observed by techniques sensitive to the lattice structure (RBS/C, TEM). The only way to detect this damage is to decorate it with metals and to measure the metal distribution. In this study the formation and disappearance of the Rp/2 damage has been investigated by Cu gettering in Si +-ion implanted Si versus temperature and time of the annealing cycle. The defects undergo a defect evolution during annealing which results in a decrease of the width of the damage layer with increasing temperature and prolonged time of the annealing. It is mostly believed that an excess of vacancies around Rp/2 getter metal impurities. Nevertheless, by means of positron annihilation spectroscopy no vacancy defects have been observed. In contrast in our XTEM investigation we found small (20-30nm) interstitial loops in the Rp/2 region. The creation of these loops is triggered by injected interstitials resulting from the ion milling procedure used during TEM specimen preparation. The ion bombardment of Si give rise to self-interstitials that diffuse extensively at room temperature and may modify the existing interstitial clusters to bigger agglomerates which can be observed by XTEM.]]></dc:description>

<dc:description><![CDATA[The analytical simulation of the counter-current flow limitation phenomenon in a PWR is an essential element to understand safety-related issues in nuclear power plants. It is expected that the introduction of computational fluid dynamics (CFD) tools will enhance the accuracy of the simulation predictions compared to the established one-dimensional thermal hydraulic analyses. Nevertheless, the use of CFD for this complicated task is still a challenge today. Due to the need to understand the CCFL phenomenon in a PWR for reasons of safety and characterisation of normal operation, it is necessary to validate computer codes and to verify computational results using experimental data. Therefore it is also interest to prove the understanding of the general fluid dynamic mechanism leading CCFL and to identify the critical parameters affecting this phenomenon.

In order to improve the transient analysis of counter-current two-phase flows, experimental and numerical studies were conducted at Forschungszentrum Dresden-Rossendorf (FZD). A 1/3rd scale model of the hot leg PWR of a German Konvoy Pressurized Water Reactor with rectangular cross section was used. The experimental results on this topic were reported in previous reports [Deendarlianto et al. (2008) & Vallée et al. (2009)]. Selected an air-water CCFL experiment at 0.15 MPa and room temperature at FZD (experimental running number 30-09) was numerically modelled with three-dimensional two-fluid models of computer code CFX 12.0 (ANSYS CFX). The aim of this CFD simulation is to validate the prediction model of the CCFL with the existing multiphase flow models built in the commercial code ANSYS CFX. CFD simulation was performed using the multi-fluid Euler-Euler modeling approach or free surface model available in CFX. The calculation was carried out in fully transient manner using a gas/liquid inhomogeneous multiphase flow model coupled with a shear stress transport (SST) turbulence model. In the present numerical study, the drag coefficient was approach by using the Algebraic Interfacial Area Density (AIAD) model. The results indicated that quantitative agreement between calculation and experimental data was obtained for the occurrence of flooding point. Next, it was found also that a comparison with the high-speed video observations shows a good qualitative agreement.]]></dc:description>

The HADES study of the light C+C system at 1 and 2 AGeV confirms former finding of the DLS collaboration. Further studies of the reaction p+p and d+p allowed to reveal contribution to the above mentioned data of di-leptons produced during first chance collision.

<dc:title><![CDATA[Autocrine regulation of receptor for advanced glycation endproducts (RAGE) by S100A4 promotes migration and invasion in A375 melanoma cells]]></dc:title>
<dc:source><![CDATA[21st Meeting of the European Association for Cancer Research (EACR-21), 26.-29.06.2010, Oslo, Norway]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background
The calcium-binding protein S100A4 is associated with metastasis of different cancer entities, including melanoma. The multiligand receptor for advanced glycation endproducts (RAGE) has been suggested to interact with extracellular S100A4 protein. We hypothesized that the interaction between RAGE and S100A4 plays an important role in activation of growth, adhesion, motility and migration in a human melanoma cell line with high metastatic potential.

Materials and methods
In order to investigate the cellular role of the RAGE-S100A4 interaction in vitro, we produced recombinant S100A4 and soluble RAGE (sRAGE). Furthermore, we established A375 melanoma cells stably transfected with S100A4 using vector pIRES2-AcGFP1 (A375-S100A4). The overexpression of S100A4 has been verified by western blot and flow cytometry. Assays for determination of migratory, invasive and adhesive behaviour of A375-S100A4 cells were performed. Furthermore, specific interaction of S100A4 with RAGE was characterized by surface plasmon resonance spectroscopy using immobilized sRAGE.

Results
The overexpression of S100A4 did not influence growth properties and adhesive behaviour of the A375-S100A4 cells; however, it affects their motility and migratory activity in comparison to mock-transfected cells. A375-S100A4 cells show an increased secretion of S100A4 into the extracellular space and, in consequence, an enhanced RAGE protein expression. Molecular interaction studies revealed high affinity (lower micromolar range) of S100A4 towards immobilized sRAGE, suggesting a biochemical rationale for the observed effects. 

Conclusion
This investigation shows that overexpression of S100A4 influences the metastatic behavior of A375 melanoma cells. The enhanced secretion of S100A4 leads to an autocrine upregulation of RAGE expression and synthesis in A375-S100A4 cells. The findings support the supposed functional role of RAGE-S100A4 interaction in promoting a metastatic phenotype of human melanoma.]]></dc:description>

<dc:title><![CDATA[Autocrine regulation of receptor for advanced glycation endproducts (RAGE) by S100A4 promotes migration and invasion in A375 melanoma cells]]></dc:title>
<dc:source><![CDATA[European Journal of Cancer 8(2010), 118-119]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background
The calcium-binding protein S100A4 is associated with metastasis of different cancer entities, including melanoma. The multiligand receptor for advanced glycation endproducts (RAGE) has been suggested to interact with extracellular S100A4 protein. We hypothesized that the interaction between RAGE and S100A4 plays an important role in activation of growth, adhesion, motility and migration in a human melanoma cell line with high metastatic potential.

Materials and methods
In order to investigate the cellular role of the RAGE-S100A4 interaction in vitro, we produced recombinant S100A4 and soluble RAGE (sRAGE). Furthermore, we established A375 melanoma cells stably transfected with S100A4 using vector pIRES2-AcGFP1 (A375-S100A4). The overexpression of S100A4 has been verified by western blot and flow cytometry. Assays for determination of migratory, invasive and adhesive behaviour of A375-S100A4 cells were performed. Furthermore, specific interaction of S100A4 with RAGE was characterized by surface plasmon resonance spectroscopy using immobilized sRAGE.

Results
The overexpression of S100A4 did not influence growth properties and adhesive behaviour of the A375-S100A4 cells; however, it affects their motility and migratory activity in comparison to mock-transfected cells. A375-S100A4 cells show an increased secretion of S100A4 into the extracellular space and, in consequence, an enhanced RAGE protein expression. Molecular interaction studies revealed high affinity (lower micromolar range) of S100A4 towards immobilized sRAGE, suggesting a biochemical rationale for the observed effects. 

Conclusion
This investigation shows that overexpression of S100A4 influences the metastatic behavior of A375 melanoma cells. The enhanced secretion of S100A4 leads to an autocrine upregulation of RAGE expression and synthesis in A375-S100A4 cells. The findings support the supposed functional role of RAGE-S100A4 interaction in promoting a metastatic phenotype of human melanoma.]]></dc:description>

<dc:description><![CDATA[Ultra-fine grained nickel samples were cyclically deformed at room temperature and at 200°C. The mean grain size of about 200 nm, determined by SEM and from the broadening of synchrotron diffraction profiles remained nearly constant, whereas the spectrunm of internal strains changed in consequence of the cyclic deformation. The relation between the profile shape ans asymmetry and the {hkl} reflection type suggests the existence of long range granular stresses in the original ufg samples.]]></dc:description>

<dc:title><![CDATA[Irradiation effects on toughness behaviour and microstructure of VVER-type Pressure Vessel Steels]]></dc:title>
<dc:source><![CDATA[Journal of Nuclear Materials 297 (2001) 251-261]]></dc:source>

<dc:description><![CDATA[The irradiation sensibility and the annealing behaviour were studied on seven different heats from VVER 440 and VVER 1000-type reactor pressure vessel steels. The specimens were irradiated at the Rheinsberg prototype VVER 2 reactor to mean neutron fluences between 43 - 127.6A1018 n/cm² [E > 0.5 MeV] and afterwards toughness and strength properties were determined. In addition the microstructure was analysed using SANS technique. There is an obvious trend regarding the correlations between the irradiation-induced changes of transition temperature, hardness and volume fraction of microstructural features of the radius near of approx. 0 to 2 nm. The main parameters of influence are the neutron fluence and the nickel content. The nickel-containing VVER 1000-type pressure vessel steel is more sensible against irradiation than the VVER 440-type steel which has a low content of nickel. For the last one the sensibility against radiation embrittlement depends on content of copper and phosphorus. Annealing at 475 °C (100 h) reduces the irradiation effect but not completely in every case.]]></dc:description>

<dc:description><![CDATA[We demonstrate the realization of a quantum cascade laser (QCL) based on strained InGaAs/AlGaAs/GaAs grown on GaAs substrate using molecular beam epitaxy. The material is compared to a GaAs/AlGaAs structure with nominally identical radiative transitions. Lasing at 10 microns was achieved in the strained and the unstrained material. The strained material shows an improved temperature performance with a T0=112K between 125 K and 200 K and a maximum working temperature of T=200 K. ]]></dc:description>

<dc:date>2001</dc:date>
<dc:description><![CDATA[It has been found that phase transformations in implanted iron may strongly depend on the sample thickness. The effect essentially relies on lower impurity concentration required for given phase formation in thin films when compared with thick layers or bulk samples and most likely should be attributed to the stress formed during layer deposition. The phase transformation in thin films is also more complete, for example full transformation of thin iron layers into iron nitrides was observed, whereas in thick and bulk samples about 20 % of Fe atoms in implanted layer remain in crystalline alpha-Fe phase. ]]></dc:description>

<dc:source><![CDATA[Talanta, 57, 999-1009 (2002)]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[Carbon-13 cross-polarization magic-angle spinning nuclear magnetic resonance spectroscopy (13C-CP/MAS-NMR) was applied to study the chemical modification process of humic acids (HA) with diazomethane and the subsequent alkaline hydrolysis of the methylated HA, which results in HA with blocked phenolic OH groups. We investigated different chemically modified and unmodified natural and synthetic HA with carbon-13 of natural abundance. In addition, we studied carbon-13 labeled modified synthetic HA, that were synthesized with [13C]diazomethane as methylation reagent, to confirm the assumed modification process and to determine the type of functional groups that have the highest affinity for methylation.
The results of the NMR studies with carbon-13 labeled HA show that carboxyl and acidic (phenolic) OH groups are methylated with diazomethane. Due to the alkaline saponification of the methylated HA, methyl esters of carboxyl groups are hydrolyzed, whereas phenolic OH groups remain methylated. Carboxyl groups show the highest affinity for methylation. 
From the spectra of the modified and unmodified HA with carbon-13 of natural abundance it can be concluded that the applied modification procedure causes only the desired structural changes in HA.]]></dc:description>

<dc:title><![CDATA[The impact of hypoxia on differential expression of neurotensin receptors (NTR) in colorectal and prostate carcinoma cells]]></dc:title>
<dc:source><![CDATA[European Journal of Cancer 8(2010), 61]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background: 
Recent studies showed increased expression of neurotensin receptors (NTR), particularly, NTR1 and NTR3, in various tumors, thus NTR is assumed a potential target for tumor imaging and therapy. However, the knowledge about the quantitative expression of NTR on mRNA and protein level, e.g., under hypoxic conditions is limited. The aim of this study was to develop a quantitative method for determination of absolute NTR mRNA amount in tumor and non-tumor cells and tissues. For method evaluation the NTR mRNA amounts in human colorectal (HT-29) and prostate (PC3) carcinoma cell lines under normoxic and hypoxic conditions in vitro were compared.

Material and methods: 
A novel real-time RT-PCR method using an external standard was established. The elongation factor 1 alpha (EF1α) gene served as housekeeping gene and glucose transporter protein type 1 gene (GLUT1) was used as indicator for cellular hypoxic regulation effects. The derived standard curves allow for calculation of the number of specific mRNA molecules normalized to 1000 molecules of EF1α. Acute and chronic experimental hypoxia was induced by cultivation of cells at an oxygen concentration of 0.6% for 4 to 72 hours. 

Results: 
Both HT-29 cells and PC3 cells show high mRNA expression of NTR1 in normoxia. In acute hypoxia (</- 24 hours) the expression level of NTR1 did not change. However, under conditions of chronic hypoxia in HT-29 cells, at the latest after 48 hours, the NTR1 mRNA expression was significantly decreased. In contrast, the NTR1 mRNA in PC3 cells remained at a high level also in hypoxia. The mRNA level of NTR3 was about 5 orders of magnitude lower than NTR1 in both cell lines. Expression of NTR3 in both cell lines showed no significant differences during hypoxia, with a tendency to increase. 

Conclusion: 
A novel standardizable and reproducible quantitative method for measurement of NTR mRNA in cancer cells was established. The use of NTR1 as a target for imaging or therapy strongly depends on tumor cell type and tumor hypoxia. Ongoing investigations will compare quantitative mRNA expression with data on functional expression of NTR, e.g., protein synthesis and radioligand interaction, in human samples and rodent tumor (xenograft) models.]]></dc:description>

<dc:title><![CDATA[Reliable micro-measurement of strontium is the key to cracking the life-history code in the fish otolith]]></dc:title>
<dc:source><![CDATA[Nuclear Instruments and Methods in Physics Research B 168 (2000) 109-116]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[The fish otolith is a calcium carbonate (usually aragonite) crystal that crows continuously by accretion over the life of the fish and unlike bone is not continuously re-metabolised. Consequently, the otolith has long been regarded as a potential store of information about the life history of an individual fish, and this information is encoded in the deposition pattern of trace elements in the otolith. The code has been difficult to crack. However, recent developments have show that: (1) Sr is one of the few non-mobile trace elements in the otolith; and (2) the pattern of Sr deposition summarises the effects of environment changes that affect the growth rate of the otolith crystal. The remaining difficulties in cracking the chemical code in the otolith have hinged about making reliable micro-measurements of the stable Sr content at spatial resolutions of 10 µm or less; this interval represents about 4-6 days of otolith growth in most species of fish. This paper describes high beam resolution 2 µm linear measurements, and 6 µm square measurements over narrow windows of about 300µm square, and links these micro-measures to macro-measures of 2D maps of the entire surface of sections of otoliths up to 5 mm square at beam resolutions of 25 µm square. The otoliths used in this study are from the Jurel, or Peruvian Jack mackerel, Trachurus murphyi (Carangidae: Teleostei).]]></dc:description>

<dc:description><![CDATA[Background 
Cyclin-dependent kinases 4 and 6 (Cdk4/6) function as critical activators of cell cycle progression in human tumors. Pyrido[2,3 d]pyrimidine derivatives CKIA and CKIE are selective Cdk4/6 inhibitors with high potency for the inhibition of G1 phase progression and tumor cell proliferation. The aim of this study was the evaluation of radiolabeled compounds [<SUP>124</SUP>I]CKIA and [<SUP>18</SUP>F]CKIE as radiotracers for PET imaging of Cdk4/6 in tumors in vivo.

Materials and methods 
Cellular uptake of radiotracers [<SUP>124</SUP>I]CKIA and [<SUP>18</SUP>F]CKIE was studied in human colorectal (HT-29) and squamous cell (FaDu) carcinoma cells. Small animal PET studies of both radiotracers were performed in FaDu xenograft-bearing nude mice.

Results 
Radiotracer uptake studies showed fast and high uptake (up to 800%ID/mg protein) of [<SUP>124</SUP>I]CKIA in both cell lines after 1 h at 37°C. Cellular uptake of [<SUP>18</SUP>F]CKIE was lower (HT 29, 46.3±11.2%ID/mg protein; FaDu, 46.2±13.8%ID/mg protein). Radiotracer uptake was significantly lower at 4°C for [<SUP>124</SUP>I]CKIA (150%ID/mg protein) and [<SUP>18</SUP>F]CKIE (15%ID/mg protein) after 1 h in both cell lines. Cellular uptake of [<SUP>18</SUP>F]CKIE was reduced to 18.0±4.9%ID/mg protein in the presence of 10 µM of nonradioactive CKIE at 37°C. Dynamic small animal PET studies showed rapid clearance of [<SUP>124</SUP>I]CKIA and [<SUP>18</SUP>F]CKIE from the blood and fast hepatobiliary excretion. The half-life of radiotracer elimination from the blood was calculated to be 7.2 min for [<SUP>124</SUP>I]CKIA and 7.9 min for [<SUP>18</SUP>F]CKIE, respectively. Radiotracers were rapidly metabolized in blood in vivo, yielding >90% (1 min p.i.), 20% (30 min), and <5% (1 h) of the original compounds. Small animal PET studies with [<SUP>124</SUP>I]CKIA only showed marginal uptake of the radiotracer in the FaDu tumor. In the case of [<SUP>18</SUP>F]CKIE a higher uptake was detected in the peripheral proliferative region of the tumor after 1 h p.i. However, the constant tumor-to-muscle ratio of 1.5 suggests a non-Cdk4/6-mediated uptake of [<SUP>18</SUP>F]CKIE in human tumor xenografts in mice.

Conclusions 
Synthesis of pyrido[2,3-d]pyrimidine-based radiotracers [<SUP>124</SUP>I]CKIA and [<SUP>18</SUP>F]CKIE allowed for the first time the quantification of cellular uptake in vitro and imaging of tissue-specific distribution of Cdk4/6 inhibitors in vivo. However, the short biological half-life in the blood and low tumor uptake of [<SUP>124</SUP>I]CKIA and [<SUP>18</SUP>F]CKIE limit the use of both radiotracers for the characterization of Cdk4/6 expression in tumors by means of PET. Further development of suitable radiolabeled Cdk4/6 inhibitors for functional characterization of Cdk4/6 in tumors continues to be of great interest in current translational cancer research.]]></dc:description>

<dc:source><![CDATA[Diamand and Related Materials 9 (2000) 657 - 679]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[The properties of polymer-like amorphous hydrogenated carbon thin films with low defect density have been studied. These films were implanted with carbon ions with a dose range of 10<SUP>12</SUP> - 10<SUP>16</SUP> cm<SUP>-2</SUP>. The purpose of the study is to investigate the effects of ion beam damage on this type of film. Optical absorption measurements observe a narrowing of the optical band gap, suggesting the introduction of a large number of defect states subsequent to the implantation resulting in the broadening of the band tails, only after a threshold ion dose of 10<SUP>15</SUP> cm<SUP>-2</SUP>. Nuclear reaction analysis suggests also a reduction in the hydrogen content of the film which coincides with film thinning.

<dc:date>2010</dc:date>
<dc:description><![CDATA[In various insulators, the impact of individual slow highly charged ions (eV-keV) creates surface nanostructures, whose size depends on the deposited potential energy. Here we report on the damage created on a cleaved BaF2 (111) surface by irradiation with 4.5×q keV highly charged xenon ions from a room-temperature electron-beam ion trap. Up to charge states q=36, no surface topographic changes on the BaF2 surface are observed by scanning force microscopy. The hidden stored damage, however, can be made visible using the technique of selective chemical etching. Each individual ion impact develops into a pyramidal etch pits, as can be concluded from a comparison of the areal density of observed etch pits with the applied ion fluence (typically 10<sup>8</sup> ions/cm<sup>2</sup>). The dimensional analysis of the measured pits reveals the significance of the deposited potential energy in the creation of lattice distortions/defects in BaF2.]]></dc:description>

<dc:source><![CDATA[Vacuum 63 (2001) 523-527]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[Tianium and his alloys are widely used in medical applications, e.g. for artifical joints, dental prosthesis, teeth and so on. However, it these metals have to be coated with ceramic facing, some stability problems in the ceramic-titanium system arise due to the strong affinity of titanium to oxygen, which causes a reduction of the ceramic oxide. It is known that this reduction effect can be mitigated by alloying titanium or its alloys with a small amount of silicon using, e.g. an ion implantation technique. In the present work, we report the results of a new approach to alloying silicon to Ti6Al4V using high intensity pulsed plasma beams. The feasibility to from the silicide Ti5Si3 with grain size larger as 75 nm is demonstrated. This silicide has the highest melting point (2130 °C) among of all stable phases in the Si-Ti system.

<dc:description><![CDATA[The morphology of the as-implanted damage in silicon is investigated using a recently developed combination of time-ordered computer simulations based on the binary collision approximation (BCA) with classical molecular dynamics (MD) calculations. The method is applied to determine the type and the amount of defects formed within the first nanosecond after ion impact. The depth profile and the total number of different defect species (vacancies, interstitials, disordered atoms, etc.) produced on average per incident ion are calculated for B+ (15 keV), P+ (5, 10, 20, 30 keV), and As+ (15 keV) implantations. It is shown that the as-implanted defect structure depends not only on the nuclear energy deposition per  ion but also explicitly on the ion mass. Therefore for each ion species the damage morphology exhibits characteristic features. For heavy ions the percentage of extended defects is higher than for light ions. In all cases investigated the number of free or isolated interstitials exceeds the amount of free vacancies. The results obtained allow a microscopic interpretation of the phenomenological model for the as-implanted damage employed in conventional BCA simulations in order to describe the dose dependence of the shape of ion range profiles. They can be also applied to get more realistic initial conditions for the simulation of the defect kinetics during post-implantation annealing.]]></dc:description>

<dc:source><![CDATA[Biometals 14 (2): 171-179 (2001)]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[The interaction of uranium with cells of three recently described eco-types of Acidithiobacillus ferrooxidans recovered from uranium mining wastes was studied. The uranium sorption studies demonstrated that the strains from these types possess different capability to accumulate and tolerate uranium. The amount of uranium biosorbed by all A. ferrooxidans strains increased with increasing the concentration of uranium. We have found that the representatives of type II accumulate significantly higher amounts of uranium in comparison to the other A. ferrooxidans strains. The investigations of the tolerance to uranium showed that the types I and III are resistant to 8 and 9 mM of uranium respectively, whereas the type II does not tolerate more than 2 mM of uranium. The recovery of the accumulated uranium by desorption was investigated using various desorbing agents as sodium carbonate, sodium citrate and EDTA at different concentrations. Sodium carbonate was the most efficient desorbing agent, removing 97% of the uranium sorbed from the cells of A. ferrooxidans type III, and 88.33 and 88.50% from the cells of the types I and II, respectively.

<dc:source><![CDATA[Applied Physics Letters Vol. 80 Number 1 , 7 January 2002, 55-57]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[It is demonstrated that the intrinsic stress in cubic boron nitride films can be significantly relaxed during growth by simultaneous medium energy ion implantation. The stress in the growing film has been studied in-situ using cantilever curvature measurements and has been reduced to below 2 GPa by simultaneous Ar+ or N+ ion implantation with an energy of 70 keV and 35 keV, respectively. The resulting cubic boron nitride films show an increased long term stability. The results reveal that the stress in cBN is not reduced due to segregation of boron at grain boundaries.]]></dc:description>

<dc:description><![CDATA[Multi-crown-dendrimers of four different generations have been synthesized by grafting 4, 8, 16 and 32 benzo[15]crown-5 units at the periphery of POPAM-dendrimers. The binding of sodium pertechnetate and mercury(II) chloride by the multi-crown-dendrimers has been studied by liquid-liquid extraction using the radioactive probes <SUP>22</SUP>Na<SUP>+</SUP>, <SUP>99</SUP>TcO<SUB>4</SUB><SUP>-</SUP>, and <SUP>203</SUP>Hg<SUP>2+</SUP>. The third- and fourth-generation dendrimers 3 and 4, in particular, are capable of extracting mercury(II) with high efficiency ( ca. 12 Hg<SUP>II</SUP> ions per dendrimer molecule, even at low generation). It has been shown that the guest molecules investigated preferentially encapsulated inside the dendrimers.

<dc:title><![CDATA[Permeation studies in vitro and in vivo of potential radiopharmaceuticals with affinity to neuro receptors]]></dc:title>
<dc:source><![CDATA[Pharmaceutical Research, Vol. 17, No. 6 (2000) 754-760]]></dc:source>
<dc:date>2000</dc:date>
<dc:description><![CDATA[PURPOSE: 
To check the influence of structural characteristics on their permeation through the blood-Brain barrier (BBB), a set of radioactive [<SUP>99m</SUP>Tc]chelates bearing amine groups was synthesized and tested in vitro as well as in vivo.

METHODS:
Compounds with different log P and pK<SUB>a</SUB> values were obtained by complex forming reactions of [<SUP>99m</SUP>Tc]pertechnetate with varying substituents. Transport was studied in rats and mice, as well as in an ECV304 cell culture model.

RESULTS:
In vitro higher permeation was found for compounds with electron attracting substituents in beta-position to the amine group (pK<SUB>a</SUB> values 7.4 to 8.3) than for those with more basic amine groups (pK<SUB>a</SUB> values > 8.9) even for similar logD<SUB>ph 7.4</SUB>. In vivo brain uptake between 0.8 and 4.8% of the injected dose (ID) per organ was found for the former, whereas < 0.4% ID were present for the latter.

CONCLUSIONS:
Three structurally diverse classes of [<SUP>99m</SUP>Tc]chelates showed distinct patterns with regard to brain uptake in vivo and BBB permeability in vitro which could not be predicted by their lipophilicity alone. The close correlation between the data from rats and mice and those obtained with cell cultures render the ECV304 cells an attractive model for the screening of new compounds.

<dc:description><![CDATA[The magnetic-field dependence of the energy spectrum of GaAs doped with nitrogen impurities is investigated. Our theoretical model is based on the phenomenological band anticrossing model (BAC) which we extended in order to include the magnetic field and electron-phonon interaction. Due to the highly localized nature of the nitrogen state, we find that the energy levels are very different from those of pure GaAs. The polaron correction results in a lower cyclotron resonance energy as compared to pure GaAs. The magneto-absorption spectrum exhibits series of asymmetric peaks close to the cyclotron energy.]]></dc:description>

<dc:description><![CDATA[Failure analysis and optimization of nanoelectronic devices require knowledge of their electrical properties. Kelvin probe force microscopy (KPFM) is a standard technique for the investigation of the surface potential. We present its applicability to locally doped semiconductors. Quantitative dopant profiling by means of KPFM is successfully shown on a conventional static random access memory (SRAM) cell and on cross-sectionally prepared Si epilayer structures by applying a recently introduced new explanation of the measured KPFM signal [1]. The presented KPFM model is also used to explain observed large conductivity differences in different Mn implanted and pulsed laser annealed Ge samples by revealing a strong variation of the Fermi level position on the µm scale in dependence on the annealing conditions [2]. 
In addition, the frequency dependence of the Kelvin bias above differently doped regions is discussed with respect to surface states and trapped charges in the thin oxide layer on top [3]. Using an active mixer, the excitation amplitude of the cantilever is almost independent of the operation frequency. As a result, KPFM measurements have to be performed at frequencies high enough so that the electrical properties of the locally doped semiconductor and not of the oxide layer are probed.

<dc:description><![CDATA[Starting from the tripodal ligand 2,2',2"-nitrilotris(ethanethiol) (NS<SUB>3</SUB>) and isocyanides (CNR) as co-ligands neutral mixed-ligand technetium(III) complexes of the general formulation [Tc(NS<SUB>3</SUB>)(CNR)] have been synthesized and characterized. The <SUP>99</SUP>Tc complexes can be obtained by a two-step reduction/substitution procedure starting from [TcO<SUB>4</SUB>]<SUP>-</SUP> via the phosphine-containing precursor complex [Tc(NS<SUB>3</SUB>)(PMe<SUB>2</SUB>Ph)]. As shown by X-ray structural analyses the complexes adopt a nearly ideal trigonal-bipyramidal geometry with the trigonal plane formed by the three thiolate sulfurs of the tripodal ligand. The central nitrogen atom of the chelate ligand and the monodendate isocyanides occupy the apical positions. 
The no-carrier-added preparation of the corresponding <SUP>99m</SUP>Tc complexes was performed by a one-step procedure starting from <SUP>99m</SUP>[TcO<SUB>4</SUB>]<SUP>-</SUP> with stannous chloride as reducing agent. 
Biodistribution studies in the rat demonstrated for the nonpolar, lipophilic compounds a significant initial brain uptake. In vitro challenge experiments with glutathione clearly indicated that no transchelation reaction occurs. Furthermore, there were no indications for reoxidation of Tc(III) to Tc(V) species or pertechnetate. We propose this type of complexes as a useful tool in designing of lipophilic<SUP> 99m</SUP>Tc or <SUP>186</SUP>Re/<SUP>188</SUP>Re radiopharmaceuticals.

<dc:title><![CDATA[Uranyl(VI) Carbonate Complex Formation: Validation of the Ca2UO2(CO3)3(aq.) Species]]></dc:title>
<dc:source><![CDATA[Radiochimica Acta 89, 511-518 (2001)]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[
We recently discovered a neutral dicalcium uranyl tricarbonate complex, Ca2UO2(CO3)3(aq.), in uranium mining  related waters /1/.  We are now reporting a further validation of the stoichiometry and the formation constant of this complex using two analytical approaches with time-resolved laser-induced fluorescence spectroscopy (TRLFS) species detection: i) titration of a non-fluorescent uranyl tricarbonate complex solution with calcium ions, and quantitative determination of the produced fluorescent calcium complex via TRLFS; and ii) variation of the calcium concentration in the complex by competitive calcium complexation with Na2EDTA.
Slope analysis of the log (fluorescence intensity) versus log [Ca2+] with both methods  have shown that  two calcium ions are bound to form the complex   Ca2UO2(CO3)3(aq.).   The formation constants determined from the two independent methods are:  i) log ßo213 = 25.26 ± 0.71 and ii) log ßo213 = 25.57 ± 0.37.
A bathochrome shift of 0.35 nm between the UO2(CO3)34- complex and the Ca2UO2(CO3)3(aq.) complex was observed in the UV-vis absorption spectrum and in the laser-induced photoacoustic spectrum (LIPAS), giving additional proof for the formation of the calcium uranyl carbonate complex. 
EXAFS spectra at the LII and LIII - edges of uranium in uranyl carbonate solutions with and without calcium did not differ significantly. A somewhat better fit to the EXAFS of the Ca2UO2(CO3)3(aq.) complex was obtained by including the U-Ca shell. From the similarities between the EXAFS of the Ca2UO2(CO3)3(aq.) species in solution and the natural mineral liebigite, we conclude that the calcium atoms are likely to be in the same positions both in the solution complex and in the solid. 
This complex  influences considerably the speciation of uranium in the pH region from 6 to 10 in calcium-rich uranium-mining-related waters.

<dc:source><![CDATA[Inorganica Chimica Acta 322 (2001) 79-86]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[Technetium(I) thioether carbonyl complexes and their reaction products with histidine were prepared and characterized by Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy , various chromatographic and electrophoretic methods and electrospray mass spectrometry. Their behaviour in aqueous solutions was studied on the carrier-added (99Tc) and the no-carrier-added (99mTc) levels. HPLC and electrophoretic studies show the identity of reaction products at both concentration levels. Technetium(I) carbonyl complexes containing a bidentate dithioether ligand, [Tc(CO)3Cl(S-S)], as well as a tridentate carboxylato thioether ligand, [Tc(CO)3(S-S-O)], undergo a ligand exchange reaction with histidine and form the complex [Tc(CO)3His]. EXAFS measurements were performed to estimate structural parameters of the dissolved technetium(I) carbonyl complexes and their reaction products after the challenge experiments. The calculated bond lengths and coordination numbers are in accordance with the expected values and confirm the ligand exchange reactions.

<dc:description><![CDATA[Abstract: Co nanoparticles fabricated by ion beam synthesis in SiO2 films were inve-stigated with TEM and SQUID technique. The variation of the thermal treatment enables the formation of Co nanoclusters of different sizes ranging from 2 to 40 nm. Small nanoclusters of about 2-3 nm are amorphous, whereas clusters above 7 nm show the configuration of cubic Co nanocrystals. Measurements of magnetization at tem-peratures between 2 K and 360 K reveal superparamagnetic behaviour for the small nanoclusters up to 3 nm and ferromagnetism for clusters above 7 nm . ]]></dc:description>

<dc:description><![CDATA[Co/Cu multilayers were prepared by cross-beam pulsed laser deposition  and characterised by high-angle X-ray diffraction as well as specular and off-specular reflection. Using synchrotron radiation at the K-edge energy of Co and Cu to enhance the scattering contrast, the study shows that the roughness of these multilayers is well described by the fractal model of self-affine structures. For the pulsed laser deposited layers an extremely large lateral correlation length, xi, of the vertically correlated interfacial roughness is found (xi >1 µm) which exceeds the xi-value of the uncorrelated roughness by about two orders. The interfaces are very jagged (roughness exponent, h, between 0.15 and 0.3). The root mean square roughness, sigma, of the Cu/Co and Co/Cu interfaces are of the same order compared with the values reported for sputtered layers. ]]></dc:description>

<dc:description><![CDATA[Purpose: Before the novel technology of laser-based particle acceleration can be used for clinical applications, several requirements have to be fulfilled. These are the supply of stable and reliable particle beams with reproducible properties, sufficient particle intensity and useable energy spectra. Additionally, a precise dose delivery in an appropriate time and the exposure of a desired irradiation field are needed. Beside these demands, consequences on dosimetry as well as on the radiobiological effect have to be investigated for ultra-short pulsed laser-accelerated particle beams. Method andMaterials: The joint project onCOOPtics, an interdisciplinary and multicenter institution focusing on the development of a laser particle accelerator for radiation oncology, is introduced. The worldwide first systematic in vitro irradiations with laser-accelerated electrons performed with the JeTi laser system will be presented focusing on the experimental setup, practical experiences and on dosimetric and radiobiological results. In a next step, cell irradiation experiments with laser-accelerated protons have been prepared. Therefore, a dedicated dosimetric system was developed. It is integrated into a device that can be installed at different laser and conventional accelerators and serves also as cell or animal irradiation device. Results: A laser accelerator was successfully optimized for systematic radiobiological experiments performed over 3 months. No significant differences between laser-accelerated and conventional 6 MeV electron beams were found. An integrated dosimetry and cell irradiation device for systematic in vitro and in vivo experiments with laser-accelerated protons was developed, characterized, calibrated and successfully tested with both continuous and pulsed proton beams. Cell irradiations with protons have been started. Conclusion: Laser accelerators can be used for radiobiological experiments, meeting all necessary requirements like homogeneity, stability and precise dose delivery. Nevertheless, before fulfilling the much higher requirements for clinical application, several improvements concerning i.e. proton energy, spectral shaping and patient safety are necessary.

<dc:title><![CDATA[Calculation of intrinsic stresses in amorphous carbon films grown by molecular dynamics simulation: from atomic to macroscopic scale]]></dc:title>
<dc:source><![CDATA[Computational Materials Science 24 (2002) 154-158]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[We present a method to calculate macroscopic bulk stresses in tetrahedral amorphous carbon (ta-C) films grown by a realistic atomic scale simulation of ion-beam deposition. Similar to real as-deposited films, the simulated films have a high content of sp3 bonded atoms and large intrinsic compressive stresses. Deriving atomic stresses from an interatomic potential and averaging them over slices inside the film, we show that average stresses in the inner film region converge to realistic values (~10 GPa) as the thickness of the slices exceeds 1 nm. The analysis of stress variation with depth reveals that in amorphous films deposited with low energy (20-30 eV) ions the highest compressive stress is attained in the region of steady-state growth, while in films grown with 80 eV ions it reaches a maximum in an intermediate layer adjacent to the crystalline substrate. The transition from graphitic carbon to ta-C is found to occur at a threshold stress of about 13 GPa]]></dc:description>

<dc:source><![CDATA[Journal of Applied Physics 91, No. 4, (2002) 2037-2044]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[During growth the micro-structural development of TiN films was studied  especially the change in texture with film thickness. The films were deposited by use of a magnetron sputtering source in a vacuum chamber equipped with two magnetron sources and mounted on a goniometer located at a synchrotron radiation beam line. X-ray diffraction and reflectivity measurements were carried out in situ to follow the microstructure as a function of film thickness. With the deposition parameters that were chosen, a crossover was observed: grains with a (002) plane parallel to the film surface dominate at small thickness, while, at larger thickness, (111) grains dominate. Recrystallization was identified as a mechanism that controls this texture development. The driving force for change of orientation of the individual grains arise from minimalization of the sum of the surface energy and the strain energy of the individual grains. ]]></dc:description>

<dc:source><![CDATA[Physical Review B 63 (2001) 165329 -1-5]]></dc:source>
<dc:date>2001</dc:date>
<dc:description><![CDATA[Ordered quantum dot patterns are generated on GaSb and InSb surfaces due to a
surface instability induced by Ar+ ion  sputtering under normal incidence.
The characteristic length of the generated patterns scales with the square
root of the ion energy over the energy range of 75 - 1800 eV. This energy
dependence is compared to the solutions of the isotropic Kuramoto-Sivashinsky
equation and allows the determination of the lateral width of the energy
distribution deposited by the incident ions in the very low energy range. We
show that the observed energy dependence is in agreement with the linear
continuum theory under the assumption that the dominant smoothing process is
due to effective ion induced diffusion without mass transport on the surface.]]></dc:description>

<dc:source><![CDATA[Surface & Coatings Technology 150 (2002) 188-198]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[The structural and phase transformations occurring in the near-surface layers of pre-quenched high-speed steel subjected to pulsed electron beam melting have been investigated.  Melting was induced by a low-energy (20–30 keV), high-current electron beam with a pulse duration of 2.5 µs and an energy densities ranging from 3 to 18 J/cm2. Using electron microscopy and x-ray diffraction it has been revealed that with increasing beam energy density gradual liquid-phase dissolution of initial globular M6C carbide particles occurs in the near-surface layer of thickness up to ~1 µm. This process is accompanied by formation of martensite crystals (gamma-phase) and an increase of residual austenite (alpha-phase) content.  When the carbide particles are completely dissolved, martensitic transformation is suppressed. In this case, a nonmisoriented structure is formed consisting predominantly of submicron cells of -phase separated by nanosized carbide interlayers.  Irradiation of cutting tools (drills) in a mode corresponding to an abrupt decrease in the content of M6C particles due to their liquid-phase dissolution enhances the wear resistance of the drills by a factor of 1.7. This is associated with the fixation of undissolved particles in the matrix, the formation of residual compressive stresses and of dispersed M3C carbide particles as well as the high (~50 %) content of the metastable -phase in the surface layer.]]></dc:description>

<dc:description><![CDATA[Failure analysis and optimization of nanoelectronic devices require knowledge of their electrical properties. Kelvin probe force microscopy (KPFM) is a standard technique for the investigation of the surface
potential. Since KPFM was developed in 1991 the measured KPFM signal was attributed to the contact potential difference (CPD) between conductive probe and sample. We show that the CPD is not suitable to describe the measured Kelvin bias in semiconductors quantitatively and introduce a unique KPFM model [1] which successfully correlates the measured Kelvin bias with the difference between Fermi energy and respective band edge. Quantitative dopant profiling is demonstrated on cross-sectionally prepared Si epilayer structures and on a Si dynamic random access memory cell.

<dc:description><![CDATA[When light is resonant with a material excitation the optical Stark or Autler-Townes (AT) effect couples the involved energy states and alters their energy, i.e. the states get dressed by the light-matter interaction. This fundamental quantum-mechanical feature of light-matter interaction was originally observed in atomic spectroscopy [1]. However, despite some theoretical work, it took a long time to the first observation of the AT effect for terahertz (THz) light coupled to hole [2] and electron [3] intersubband transitions in semiconductor quantum wells. 
 Here, we report clear evidence of the intra-excitonic AT effect. In our experimental work we study the NIR transmission at low temperature of a GaAs/AlGaAs multiple quantum well film (substrate etched away) exposed to strong picosecond THz pulses from the free-electron laser (FEL) at FZD. NIR spectra are recorded for a series of different THz frequencies and intensities. When tuning the THz photon energy in the range from 6 to 17 meV around the 1s-2p intra-excitonic transition energy that lies at ~9 meV, we observe a line splitting when pumping near resonance, and low- and high-energy shoulders, respectively, when pumping off resonance. This behavior is consistent with the AT effect. In Fig. 1 the measured absorption around the heavy-hole 1s exciton is displayed for different THz photon energies, showing the two dressed states and their expected anticrossing behavior. We discuss our experimental evidence of a coupling between the NIR bright 1s state and the NIR dark 2p state on the basis of a two-level model. Near resonance (10.5 meV) we find that our simplified model describes the situation surprisingly well up to a THz field strength of 10 kV/cm (I = 650 kW/cm<sup>2</sup>), corresponding to a Rabi energy of 0.6 times the 1s-2p transition energy. This is already well beyond the limits of the rotating-wave approximation. At the highest field strengths, the Rabi sidebands appear to start interacting with other exciton states. A full many-body theory would have to deal with the complete manifold of excitonic states as well as with the possibility of exciton field ionization. Note that for the above parameters in our case the ponderomotive energy is 3 meV and thus of the same order as the exciton transition/ionization energy (i.e. Keldysh parameter near unity) and the Rabi energy, an extremely non-trivial regime.
Using picosecond THz pulses we finally demonstrate that the induced absorption change occurs adiabatically only during the THz pulse. This ultrashort change that corresponds to an up to 20-fold increase in transmission can in principle be exploited in NIR modulators or switches.

<dc:source><![CDATA[ICPS 2010, 30th International Conference on the Physics of Semiconductors, 25.-30.07.2010, Seoul, Südkorea]]></dc:source>

<dc:description><![CDATA[When light is resonant with a material excitation the optical Stark or Autler-Townes (AT) effect couples the involved energy states and alters their energy, i.e. the states get dressed by the light-matter interaction. This fundamental quantum-mechanical feature of light-matter interaction was originally observed in atomic spectroscopy [1]. However, despite some theoretical work, it took a long time to the first observation of the AT effect for terahertz (THz) light coupled to hole [2] and electron [3] intersubband transitions in semiconductor quantum wells. 
 Here, we report clear evidence of the intra-excitonic AT effect. In our experimental work we study the NIR transmission at low temperature of a GaAs/AlGaAs multiple quantum well film (substrate etched away) exposed to strong picosecond THz pulses from the free-electron laser (FEL) at FZD. NIR spectra are recorded for a series of different THz frequencies and intensities. When tuning the THz photon energy in the range from 6 to 17 meV around the 1s-2p intra-excitonic transition energy that lies at ~9 meV, we observe a line splitting when pumping near resonance, and low- and high-energy shoulders, respectively, when pumping off resonance. This behavior is consistent with the AT effect. In Fig. 1 the measured absorption around the heavy-hole 1s exciton is displayed for different THz photon energies, showing the two dressed states and their expected anticrossing behavior. We discuss our experimental evidence of a coupling between the NIR bright 1s state and the NIR dark 2p state on the basis of a two-level model. Near resonance (10.5 meV) we find that our simplified model describes the situation surprisingly well up to a THz field strength of 10 kV/cm (I = 650 kW/cm<sup>2</sup>), corresponding to a Rabi energy of 0.6 times the 1s-2p transition energy. This is already well beyond the limits of the rotating-wave approximation. At the highest field strengths, the Rabi sidebands appear to start interacting with other exciton states. A full many-body theory would have to deal with the complete manifold of excitonic states as well as with the possibility of exciton field ionization. Note that for the above parameters in our case the ponderomotive energy is 3 meV and thus of the same order as the exciton transition/ionization energy (i.e. Keldysh parameter near unity) and the Rabi energy, an extremely non-trivial regime.
Using picosecond THz pulses we finally demonstrate that the induced absorption change occurs adiabatically only during the THz pulse. This ultrashort change that corresponds to an up to 20-fold increase in transmission can in principle be exploited in NIR modulators or switches.

<dc:source><![CDATA[Electrochimica Acta 56(2011)6, 2665-2675]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[The effect of a uniform magnetic field on the hydrogen evolution reaction (HER) during water electrolysis in 0.1 M Na2SO4 solution was investigated. Irrespective of the magnetic field orientation with respect to the electrode surface, the desorption of hydrogen is enhanced by the presence of the magnetic field. This effect is displayed by a reduction of the mean bubble size as well as a narrower bubble size distribution in a magnetic field. Moreover, it is shown that in the presence of an external magnetic field the fractional bubble coverage is strongly retarded. As a consequence the current density is increased since more active sitesare available for the reduction processes. These effects are discussed with respect to the Lorentz force driven convection induced by a magnetic field. In order to resolve further the influence of a magnetic field applied in the perpendicular-to-electrode configuration, where the bulk Lorentz force is negligible, a numerical study has been performed. This revealed the mechanism of the improved desorption of a hydrogen bubble from the electrode surface. The numerical study has been validated by a model experiment. Most importantly, it is clearly demonstrated that a magnetic field superposed during water decomposition is a very effective method to intensify hydrogen evolution processes, and it should be possible to significantly improve the energetic efficiency of the hydrogen production via water electrolysis in a magnetic field.]]></dc:description>

<dc:description><![CDATA[Purpose: The novel technology of laser based particle acceleration promises accelerators of compact size and reasonable costs that may significantly contribute to a widespread use of ion radiotherapy. Although some basic properties of laser acceleration are reasonably well known from theory, simulations and fundamental experiments, several demands have to be fulfilled for its medical application. Moreover, the ultra-short pulsed particle beams with resulting high pulse dose-rate have to be characterized with regard to their radiobiological properties. Therefore, a precise dosimetry is necessary that considers the special characteristics of the laser accelerated protons. Special attention has to be drawn on the low energy (<10 MeV), the exponential energy spectrum, the low repetition rate and the pulse-to-pulse fluctuations of the available laser accelerated proton beams.

Material & Methods: An Integrated Dosimetry and Cell Irradiation Device (IDCID) for systematic in vitro and in vivo experiments with laser accelerated protons was developed and characterized. The IDCID (Fig. 1) consists of a kapton vacuum window, an ionisation chamber consisting of ultra-thin foils (22.5 µm) for online dose information and a Faraday cup inset for absolute dosimetry that can be replaced by an inset for cell or even mouse model irradiation. Radiochromic films, i.e. GafChromic EBT, or CR-39 solid state track detectors can be included matching the plane of the cell monolayer. For the use of the Faraday Cup (FC) for absolute dosimetry and cross-calibration of the ionisation chamber, an accurate FC calibration is necessary. Therefore, three independent ways were chosen: (1) electronic calibration by applying a defined charge to the FC amplifier, (2) dose calibration against a clinical established absolute dosimetry and (3) calibration with CR-39 solid state track detectors. The dose calibration was performed at the proton therapy facility at the Helmholtz Zentrum Berlin, where also EBT and EBT2 films were calibrated for determination of 2D dose distribution. Moreover, the FC calibration with the help of CR-39 was carried out at the Tandem accelerator of the Forschungszentrum Dresden-Rossendorf.

Results: Successfully, the functional capability of the IDCID was thoroughly tested and precisely calibrated with three independent methods. EBT / EBT2 films were calibrated for several proton beam qualities with mean energies between 5 - 62 MeV. As next step, first systematic in vitro cell irradiations were performed for a human squamous cell carcinoma (FaDu) cell line irradiated with 7 MeV monoenergetic protons.

Conclusion: Both the dosimetric and radiobiological requirements for systematic cell irradiations with laser accelerated protons have been fulfilled.

Moreover, the ultra-short pulsed particle beams with resulting high pulse dose-rate have to be characterized with regard to their radiobiological properties. Therefore, a precise dosimetry is necessary that considers the special characteristics of the laser accelerated protons. Special attention has to be drawn on the low energy (<10 MeV), the exponential energy spectrum, the low repetition rate and the pulse-to-pulse fluctuations of the available laser accelerated proton beams.

Material & Methods: An Integrated Dosimetry and Cell Irradiation Device (IDCID) for systematic in vitro and in vivo experiments with laser accelerated protons was developed and characterized. The IDCID (Fig. 1) consists of a kapton vacuum window, an ionisation chamber consisting of ultra-thin foils (22.5 µm) for online dose information and a Faraday cup inset for absolute dosimetry that can be replaced by an inset for cell or even mouse model irradiation. Radiochromic films, i.e. GafChromic EBT, or CR-39 solid state track detectors can be included matching the plane of the cell monolayer. For the use of the Faraday Cup (FC) for absolute dosimetry and cross-calibration of the ionisation chamber, an accurate FC calibration is necessary. Therefore, three independent ways were chosen: (1) electronic calibration by applying a defined charge to the FC amplifier, (2) dose calibration against a clinical established absolute dosimetry and (3) calibration with CR-39 solid state track detectors. The dose calibration was performed at the proton therapy facility at the Helmholtz Zentrum Berlin, where also EBT and EBT2 films were calibrated for determination of 2D dose distribution. Moreover, the FC calibration with the help of CR-39 was carried out at the Tandem accelerator of the Forschungszentrum Dresden-Rossendorf.

Results: Successfully, the functional capability of the IDCID was thoroughly tested and precisely calibrated with three independent methods. EBT / EBT2 films were calibrated for several proton beam qualities with mean energies between 5 - 62 MeV. As next step, first systematic in vitro cell irradiations were performed for a human squamous cell carcinoma (FaDu) cell line irradiated with 7 MeV monoenergetic protons.

Conclusion: Both the dosimetric and radiobiological requirements for systematic cell irradiations with laser accelerated protons have been fulfilled.

<dc:source><![CDATA[Applied Geochemistry 26(2011), 2134-2146]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[An on-site gas monitoring study has been conducted in the framework of an earthquake laboratory (the international NELSAM-DAFGAS projects) at the TauTona Gold mine, South Africa.  Extensive underground activities began in 2004 with the establishment of a 25 m² cubby and the drilling of five boreholes up to 60 m apart within the Pretorius Fault zone at 3.54 km depth.  Instruments for chemical and seismic monitoring were then installed within the cubby and boreholes. Since 2007 sensitive gas monitoring devices have been continuously improved to enable the direct observation of geogas concentration variations in the DAFGAS borehole. The major gas concentrations are constant and air-like with about 78% N<sub>2</sub>, 21% O<sub>2</sub>, 1% Ar, while the geogas components CO<sub>2</sub>, CH<sub>4</sub>, He and H<sub>2</sub> show most interesting trends and variations on the minute-by-minute basis.  Time series and cross correlation analysis with meteorologic and seismic data allow the identification of two different gas components (geogas and tunnel air) and the identification of the two most significant processes influencing the borehole gas composition: 1) pumping-induced tunnel air breakthrough events through networks of initially water-saturated fault fractures; and 2) blasting induced permeability enhancement of the fault fractures to above ~5*10<sup>-10</sup> m².  The current set-up of the gas monitoring system is sensitive enough to quantify the resulting geogas transport during periods of intense blasting activities (including recorded blasts with seismic moment ≤ 1*10<sup>9</sup> Nm, located within 1000 m of the cubby) – and, we suggest, also during induced earthquakes – a final goal of the project.]]></dc:description>

<dc:date>2002</dc:date>
<dc:description><![CDATA[
Si+ ion implantation into Si under inclined incidence angle was applied to demonstrate that Cu gettering in the region around half of the projected ion range, RP/2, of ion-implanted Si is controlled by the same mechanism working for excess vacancy generation. The obtained results directly relate the appearance of the RP/2 gettering effect to radiation-induced excess vacancies. Excess vacancies were found to be origin for the dominating gettering sites of Cu at RP/2. Moreover, it was shown that the undesired impurity trapping at RP/2 can be prevented by means of additional Si+ implantation into the vacancy-rich region of ion-implanted Si to balance the excess of vacancies. The parameters were determined for the additional Si+ implantation to remove Cu gettering at RP/2. If the threshold fluence necessary to remove the Cu gettering at RP/2 is exceeded, the excess vacancies are overcompensated and new interstitial-type dislocation loops form.

<dc:date>2011</dc:date>
<dc:description><![CDATA[Magnetic vortices show promise as data storage structures, however the vortex formation process imposes a lower limit on the element’s size. In this article a technique is presented, which application increases the probability of nucleating of magnetic vortices in sub-micron sized soft magnetic thin film elements. By tailoring the edge geometry of the elements, the symmetry of their magnetic configuration is broken in a manner which favors vortex nucleation. Micromagnetic simulations are presented, which demonstrate this effect in soft-magnetic disks with beveled edges. The favored edge geometry was realized by applying nanosphere lithography directly on top of a ferromagnetic thin film material. The resulting magnetic reversal loops show that in both magnetically isolated as well as in closely packed arrays of beveled disks, vortex formation takes place. The technique presented facilitates the vortex formation even in closely packed and small elements. The lowering of the minimum critical diameter for vortex formation enables a significant increase of data storage density in devices based on magnetic vortices.]]></dc:description>

<dc:description><![CDATA[Art objects of glass are subjected to ageing processes even under air conditioning of museums. Glass surfaces are decomposed and sometimes their transparency is considerably reduced. This is the consequence of chemical processes which take place between the silicate network and the humidity of the ambient atmosphere. In particular, potassium-calcium-silica glasses are affected. Degradation takes place via ion exchange reactions where potassium and calcium are leached out and hydrogen-bearing species are incorporated into the silicate structure. Endangered glass objects of museums should be indicated by means of non-destructive composition analysis. Simultaneous use of the ion beam methods PIXE, PIGE and RBS at a non-vacuum facility proves ideal to determine both the corrosion state of the glass surface and the composition of the glass bulk. The results allow recommendations to museums regarding demands of special storage conditions. Art scientists may deduce details on the glass prove-nience or on special manufacturing technologies.]]></dc:description>

<dc:description><![CDATA[Results of ac-susceptibility, specific-heat, magnetization, and electron-spin-resonance studies of a [Gd<sub>2</sub>(fum)<sub>3</sub>(H<sub>2</sub>O)<sub>4</sub>]·3H<sub>2</sub>O  (fum=fumarate, C<sub>4</sub>H<sub>2</sub>O<sub>4</sub>) powder samples are reported. The results of these measurements enabled us to identify the studied compound as a three-dimensional S = 7/2 Heisenberg magnet with T<sub>N</sub> = 0.19 K and dominant crystal-field anisotropy. The susceptibility studies conducted at audio frequencies and temperatures from 2 to 30 K revealed that the application of static magnetic fields induces a slow spin relaxation. The relaxation is not associated with an anisotropy energy barrier and is explicable assuming resonant phonon trapping. The magnetic field dependence of the relaxation time is consistent with the proposed scenario and suggests that a strong spin-lattice interaction may be the mechanism governing the relaxation properties in the studied system]]></dc:description>

<dc:description><![CDATA[In the Forschungszentrum Rossendorf (FZR), an infrared FEL at the radiation source ELBE is under construction. For the measurements of the electron beam position in the undulator, two systems will be used. The first one consists of seven insertable beryllium OTR (Optical Transition Radiation) view screens, which will also be used for the alignment of the FEL optical resonator. The second one will use a single moveable YAG (Yttrium Aluminium Garnet activated by Cerium) screen, which can travel within the undulator vacuum chamber such that the electron beam position can be measured at any place in the undulator.]]></dc:description>

<dc:source><![CDATA[Physical Review B 82(2010), 024422]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The standard model of rare-earth magnetism assumes that magnetic anisotropy is mainly caused by single-ion effects. The importance of two-ion anisotropy is still disputed. For a number of materials this two-ion anisotropy is in the same order of magnitude and strongly influences the magnetic properties. Single crystalline Tb<sub>5</sub>Ge<sub>3</sub> has a high moment and low symmetry and, because of this, a large anisotropy is expected. In the present study the influence of the two-ion interaction was investigated. Magnetization and magnetostriction were measured in high magnetic fields up to 60 T. The magnetic phase diagram constructed for the main crystallographic directions shows antiferromagnetism in zero field and a number of magnetic phases at higher fields. The exchange interaction was evaluated based on a model calculation of these phase diagrams. We conclude that a huge anisotropy in the two-ion interaction is present, which overwhelms the single-ion effects.]]></dc:description>

<dc:description><![CDATA[Based on previous results on laser cooling of relativistic c3+ ion beams at the ESR storage ring we present new laser systems and optical diagnostics for laser cooling of relativistic ion beams.
In combination with a new Schottky detection and new beam profile measurement system currently tested at the ESR the new optical diagnostics will help to give new insight into the dynamics of laser cooled ion beams with unprecedented resolution.
With a scanning and a pulsed laser system newly introduced to the experiment we will be able to cool relativistic ion beams without the need of electron precooling. This will be of great importance for the laser cooling experiments at higher energies available at future storage rings.]]></dc:description>

<dc:source><![CDATA[Chemical Research in Toxicology 24(2011), 193-203]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[Radionuclides represent a serious health risk to humans in case of incorporation. To get a first insight into the transport and metabolism of trivalent actinides in the human organism, we investigated the in vitro speciation of curium(III) in human urine samples using fluorescence spectroscopy. Since in speciation studies trivalent lanthanides are often used as analogs for trivalent actinides, we probed the suitability of this theory by investigating the speciation of europium(III) in human urine, too. Comparison with reference spectra of both heavy metals in model urine and of their complexes with single organic urine constituents then allowed for the determination of the dominant species. Furthermore the chemical composition of all urine samples was analyzed and the parameters affecting the metals speciation were determined. Surprisingly the chemical composition of the natural urine samples does not seem to have a great influence on the dominant species. Instead the pH was found to be the most important parameter. For both, the actinide and the lanthanide, two analog species were identified in dependence on the pH: In samples with slight acidic pH a curium(III) and europium(III) citrate complex dominates, respectively, while in samples with near neutral pH a ternary complex with phosphate and citrate as ligands is formed in each case. Comparison with thermodynamic modeling yields some discrepancies especially at higher pH which is due to a lack of data for the ternary species of both heavy metals.]]></dc:description>

<dc:description><![CDATA[Low energy ion implantation into SiO2 causes a damaged layer near the surface. The high amount of broken bonds due to displaced Si and O atoms forms a more or less "open glassy network" in which moisture from the ambient can be absorbed. Therefore chemical reactions of the implanted impurities with hydrogen and oxygen must be expected during subsequent annealing. Water absorption in heavy ion damaged SiO2 layers has been studied by hydrogen depth profiling using the Nuclear Reaction Analysis (NRA). SiO2 was implanted with ions of different mass (Si, Ge, Sn) and doses in the range 1013...1016 cm-2. H depth profiles were measured after a certain storage under clean room conditions (40 % rel.hum.) and after additional wet cleaning as well as after certain annealing. At the surface and in the region of the implanted profile the H concentration reaches (5...10) at% after storage and increases during wet chemical cleaning up to 12 at% for implantation doses  > 1*1014 cm-2.]]></dc:description>

<dc:description><![CDATA[The structure for the development of a fuel element design with reduced sodium void achieved by the use of the moderating material ZrH is investigated. In the study the sodium void effect, as well as the major feedback coefficients are analyzed. Besides the feedback coefficients, the influence on the operational parameters like neutron flux distribution, power distribution, and burnup distribution is investigated for the different possibilities of arranging the moderating material in the fuel element. Additionally, the fuel cycle parameters breeding and minor actinide production are analyzed. For a first evaluation of the behavior during transients the influence of temperature changes in the ZrH and the consequences of dissociation of the ZrH on the fuel element power are studied.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Nanopatterning solid surfaces by low-energy ion bombardment has received considerable interest in the recent years. This interest was partially motivated by promising applications of nanopatterned substrates in the production of functional surfaces. Especially nanoscale ripple patterns on Si surfaces have attracted attention both from a fundamental and an application related point of view. This paper summarizes the theoretical basics of ion-induced pattern formation and compares the predictions of the various continuum models to experimental observations with special emphasis on the morphology development of Si surfaces during sub-keV ion sputtering.]]></dc:description>

<dc:description><![CDATA[Over the past decade, molecular imaging has revolutionized medical diagnostics especially the detection of cancer. Among this new frontier, positron emission tomography (PET) allows early diagnoses, efficient monitoring of therapeutic treatment, and quantitative imaging of cancer. One of the most attractive positron-emitting radionuclide is <SUP>64</SUP>Cu, which is meanwhile readily available in high specific activity from small cyclotrons. <SUP>64</SUP>Cu-labeled peptides represent very interesting vector molecules for certain entities of cancer.

Figure 1: Bifunctional chelating agents (BFCAs) for stable binding of copper radionuclides (arrows show the position of BFCAs for the linkage to peptides) 

Pyridine-containing macrocyclic amine ligands I, bispidine II and cyclam tetrapropionic acid III derivatives (Fig. 1), which simultaneously allow the coupling to peptides, have been developed for the stable fixation of copper radionuclides.<SUP>[1-3]</SUP> Corresponding bioconjugates with bombesin as well as neurotensin form rapidly very stable radiocopper complexes which permit clear visualization of tumor tissue in small animal PET studies.

Acceleration of these computations is always a major task since the run time of the simulations representing sequential algorithms is in the range of several months. We developed an implementation for the KPZ equation on graphics processing units (GPU) using the Compute Unified Device Architecture (CUDA).

<dc:description><![CDATA[Reactive pulsed magnetron sputtering (RPMS) is employed to grow Al-doped ZnO (AZO) films on fused silica and epitaxially on Al2O3(001). The RPMS process window for obtaining highly transparent and conductive AZO with high mobility and the influence of process parameters such as oxygen partial pressure and substrate temperature are discussed. It is shown that the optimum electrical properties depend stronly on the Al concentration of the sputtering target and that mobility on fused silica is limited to about 45 cm²/Vs. The relations between depostion conditions and film microstructure, stochiometry and electrical properties are investigated, pointing to an enrichment of Al with increasing substrate temperature leading to a deterioration of crystalline structure and carrier mobility. 
Finally the observed limitations of electrical properties are categorized and discussed in terms of ionized impurity scattering and grain boundary limited transport.]]></dc:description>

<dc:source><![CDATA[5th Forum on New Materials (in the framework of 12th International Conference on Modern Materials and Technologies - CIMTEC 2010), 13.-18.06.2010, Montecatini Terme, Italy]]></dc:source>

<dc:description><![CDATA[Resistivity of ZnO:Al (AZO) films is known to increase significantly during annealing or growth at temperatures higher than certain optimum value that is a problem during preparation of thin film solar cells. To understand this process, AZO films with different Al concentrations grown by reactive pulsed magnetron sputtering were studied. The electrical resistivity of the films shows a minimum at an optimum substrate temperature, which shifts from 400 °C to 200 °C with increasing Zn/O flux ratio. At higher temperatures, resistivity increases due to simultaneous decrease of the free electron density and mobility. It is accompanied by a significant deterioration of the film crystallinity, increase of Al concentration and drop of the growth rate. X-ray absorption near edge structures (XANES) excludes formation of aluminum oxides in this case. It shows formation of homologous phase (ZnO)3(Al2O3) whose formation is triggered by an increase of the Al/Zn ratio in the film. Therefore, at growth temperatures above the optimum value Al preferentially forms this phase instead of occupying Zn site in the lattice.]]></dc:description>

<dc:description><![CDATA[In many metal casting processes the flow structure in the mould is very important for the produced material. For instance the flow field in the mould in the continuous casting process plays an important role for slug entrainment and surface defects. The measurement of that velocity field is very difficult due to the opaqueness and the high temperature of the liquid steel. One possible measurement technique is the contactless inductive flow tomography (CIFT), which is able to reconstruct the three dimensional velocity field in electrically conducting melts from externally measured induced magnetic fields.
Since for thin slab casting the velocity can be assumed to be mainly two-dimensional it is sufficient to apply only one external magnetic field and to measure the induced fields at the narrow faces of the mould. We utilize CIFT for visualizing the flow of GaInSn in a model of continuous steel casting. In a first step we show that a numerically determined flow field can be reconstructed by CIFT with an empirical correlation coefficient of nearly 80 per cent. Then we apply the method to the real model and show that typical flow features can be reliably detected.]]></dc:description>

<dc:description><![CDATA[The mechanically controllable break junction technique is used to study charge transport through suspended DNA molecules. The current-voltage (I-V) characteristics in an aqueous solution display series of negative differential resistance (NDR) and hysteresis behavior. Under high-vacuum conditions, the peak positions of NDR shift to lower voltage, and the amplitude is reduced dramatically. The observed NDR behavior is consistent with the polarization mechanism in DNA molecular junctions, which demonstrates a change in the coupling of the molecular level to a polaron mode under different environment.]]></dc:description>

<dc:description><![CDATA[Optical properties and interdot transfer dynamics of trapped carriers in InGaAs quantum dots (QDs) are investigated. Time resolved photoluminescence (PL) was measured for time-delayed interband and intraband excitations. Terahertz activated luminescence (TAL) from trapped carriers having lifetimes of ~250 ns at 8 K, was observed. Spectral shift of the TAL with respect to the PL showed the trionic nature of the PL in the n-doped QDs. With increasing terahertz excitation intensity, the TAL increased and reached saturation. The activation energy associated with the trapped carrier decay was quite close to the intersublevel transition energy (~20 meV) indicating trapping in the QDs.]]></dc:description>

<dc:description><![CDATA[Segregation of Al2O3 or ZnAl2O4 in Al-doped ZnO (AZO) is often discussed as a reason for deterioration of the film electrical properties during growth at temperatures above a certain optimum value (150-300 °C). However, conclusive evidence of these phase segregation in AZO is lacking since electrical properties and crystallinity of the films deteriorate simultaneously and, the disordered structure precludes a proper analysis using conventional methods. The present work overcomes these limitations using characterization techniques based on synchrotron radiation, such as X-ray diffraction and X-ray absorption near edge structures. These studies were combined with investigations by spectroscopic ellipsometry, Hall effect measurements and elastic recoil detection analysis. The AZO films grown by reactive pulsed magnetron sputtering at substrate temperatures, Ts, ranging from RT to 550 °C, were investigated. It is found that Al-sites in an insulating metastable homologous (ZnO)3Al2O3 phase are favored above an optimum Ts value (200-400 °C), which depends on the metal/oxygen flux ratio. Energy deposition during growth due to the elevated TS and from the flux of energetic particles incident on the substrate causes preferential Zn desorption. Thus, increasing TS above the optimum value leads to a higher Al concentration (cFAl) in the films, as compared with that of the sputter targets. It exceeds the solubility limit and triggers the formation of this phase, whose volume fraction scales with increasing cFAl. This impedes crystal growth, causes a significant increase of free electron scattering, and results in an increase of the film electrical resistivity. It is shown that one can grow low-resistivity AZO films in a wider range of TS using lower metal/oxygen flux ratios during deposition. This may be suggested as an approach to minimizing the effect of such undesirable phase formation on AZO film electrical properties.]]></dc:description>

<dc:description><![CDATA[The design of a nuclear waste repository is a challenging technological entreprise. The reasons are intrinsically related to the nature of the problem: the storage of a variety of radioactive materials for a period longer than human history. The potential consequences of a repository failure are dramatic because they lead to high environmental impact and economical costs of remediation [1]. Repository implementation should therefore rely on deep process understanding and intrinsic passive safety of geological systems. Modern approaches to the geological storage of nuclear wastes deal with a careful site selection and a multi-barrier system. The Swiss waste disposal program is currently in the final stage of the site selection process. Three geological location identified as potential disposal sites are located in Opalinus Clay formations. The multi-barrier disposal concept is heavily relying on the physical and chemical properties of clay minerals, in particular, their interaction with radionuclides [2]. 
The minerals clays of interest (illite and montmorillonite) were studied over years to derive empirically the sorption properties necessary for the safety assessments. Natural systems are heterogeneous in terms of mineralogical and chemical composition. The experimental studies are limited to a finite number of scenarios, simplified chemistry and short timescale. A mechanistic description of the sorption processes is necessary to transfer the data obtained from simplified reference systems to complex natural environments using computational models based on physical and chemical process understanding. A synthetic clay, saponite, was selected as the customizable and chemically pure starting material. Sorption experiments were carried out to obtain sorption isotherms for a divalent transition metal (nickel) and a trivalent lanthanide (lutetium). The mechanistic information about the sorption processes was achieved by X-ray spectroscopy techniques that have been carried out at the Rossendorf Beamline at the European Synchrotron Radiation Facility. The spectroscopic data are interpreted with help of ab initio molecular dynamics simulations.

<dc:title><![CDATA[Hysteresis in the magneto-transport of Manganese-doped Germanium: evidence for carrier-mediated ferromagnetism]]></dc:title>
<dc:source><![CDATA[30th International Conference on the Physics of Semiconductors, 25.-30.07.2010, Seoul,, korea]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The III-V compound GaMnAs is considered as being the prototype diluted ferromagnetic semiconductor (FMS), exhibiting negative magnetoresistance (MR) and anomalous Hall effect (AHE) related to carrier-mediated ferromagnetism. However, it would be very desirable to have a group-IV FMS, being compatible with silicon technology. In particular manganese-doped germanium prepared using low-temperature molecular beam epitaxy (LT-MBE) has proven to be a very promising material [1]. Still, no direct correspondence between transport and magnetization data has been reported yet to date. The reported MR and AHE in Ge:Mn are likely caused by (super)paramagnetic Mn ions or precipitates or by two-band-like conduction [2]. We believe that the origin of these observations lies in the less effective substitution of Mn at Ge sites, which results in too low a hole concentration, making carrier-mediated ferromagnetism impossible. The hole concentrations realized in Ge:Mn grown by LT-MBE are mostly well below 10<sup>19</sup> cm<sup>-3</sup>, which indicates the possible unsuitability of LT-MBE to achieve a large hole concentration in Ge:Mn. 

In this contribution, we show that the hole concentration can be increased by two orders of magnitude, from 10<sup>18</sup> to 10<sup>20</sup> cm<sup>-3</sup>, through Mn-ion implantation into Ge followed by pulsed laser annealing [3]. In Mn-doped Ge with a hole-concentration of around 2.1×10<sup>20</sup> cm<sup>-3</sup>, we observe that the longitudinal (Fig. 1c) and the Hall (Fig. 1b) resistance exhibit the same hysteresis as the magnetization (Fig. 1a) at temperatures below 10 K. This hysteresis in magneto-transport is usually considered as a direct evidence of carrier-mediated ferromagnetism. In sharp contrast to this, such effects are absent in Mn-doped Ge with a smaller hole-concentration. Below 10 K, the resistance of Ge:Mn films is nearly constant, i.e., quasi metallic, while from 10 to 20 K it decreases steeply with an activation energy of 4 meV. The magnetic and magneto-transport properties can be qualitatively well explained within a picture of dopant segregation and the formation of bound magnetic polarons. We will present a comprehensive correlation between the magnetic, transport and structural properties of Ge:Mn samples with different hole concentrations, as well as a comparison with literature. Note that ion implantation followed by pulsed laser annealing is an established scalable chip technology and may have a significant industry impact.

<dc:description><![CDATA[The creation of surface nanostructures in BaF2 (111) surfaces was studied after irradiation with slow highly charged Xe ions from the Dresden-EBIT (Electron Beam Ion Trap). After irradiation, the crystals were investigated by scanning force microscopy (SFM). Using specific ion parameters, the topographic images show nanohillocks emerging from the surface. Additionally, we used the technique of selective chemical etching to reveal the lattice damage created by ion energy deposition below and above threshold needed for surface hillocks formation. The role of both potential and kinetic energy as well as a comparison with results for swift heavy ion irradiations of BaF2 single crystals are presented.]]></dc:description>

<dc:date>2011</dc:date>
<dc:description><![CDATA[U(VI) accumulation by the acidothermophilic archaeon Sulfolobus acidocaldarius at pH 4.5 and 6 was investigated. These pH values are relevant for some heavy metal and uranium polluted environments where populations of S. acidocaldarius were found to persist. We demonstrate that at these pH values U(VI) is rapidly complexed by the archaeal cells. A combination of X-ray absorption spectroscopy and time-resolved laser induced fluorescence spectroscopy revealed that at pH 4.5 both, organic phosphate and carboxylic groups are involved in the U(VI) complexation. In addition, at this pH, part of the added U(VI) was precipitated in inorganic uranyl phosphate mineral phases. These mineral phases were the most predominant uranium complexes found after the treatment of the cells with U(VI) at pH 6. Transmission electron microscopic analysis of the cells treated at pH 4.5 showed extracellular and intracellular U(VI) accumulates. The extracellular complexes represented mainly inorganic uranyl phosphate complexes. The formation of the intracellular uranyl phosphate deposits is attributed to uncontrolled uptake of U(VI) as a result of the increased cell permeability, most likely due to the stress of the non-optimal pH and uranium toxicity. Our results demonstrate that at moderate acidic conditions S. acidocaldarius immobilizes U(VI) via biosorption and biomineralization processes.]]></dc:description>

<dc:description><![CDATA[Focused ion beam (FIB) techniques are one way to modify locally the properties of magnetic thin films. In previous works it was demonstrated that focused-ion-beam irradiation causes a considerable grain growth in magnetic thin films under certain conditions and therefore a change of their magnetic properties [1]. Although the grain growth can be already qualified by simple REM images a crystallographic tool is needed for a qualitative analysis. We used the advantage of nondestructive X-ray diffraction to study the grain growth.
A magnetic thin film of 50nm thick permalloy film (Fe0.2Ni0.8) sputtered on Si was used for the investigations. We have analyzed two simple parameters such as the grain size and the microstrain depending on the ion dose and beam current. Due to the very small structures created by focused-ion-beam techniques (usually less then 0.4x0.4mm2 size) an optimized X-ray laboratory setup with a focused X-ray beam of 200µm was used.

<dc:description><![CDATA[We investigated the immobilization of the estrogen receptors hER<sub>α</sub> on the silanized SiO<sub>2</sub> surfaces for biosensor applications. The conjugation of the estrogen receptor hER<sub>α</sub> to the quantum dot dye QD655 was achieved. In order to obtain an optimal immobilization of the estrogen receptor hER<sub>α</sub> on the functionalized SiO<sub>2</sub> surface, the bioconjugate hER<sub>α</sub>-QD655 (Rcpt-qd655) solution was prepared with higher a molarity ratio of 10 to 20 between the QDs and the receptors. A blue laser with an excitation wavelength of 405 nm was used for photoluminescence spectroscopy (PL) investigations to monitor the bioconjugate Rcpt-qd655 immobilization on the silanized SiO<sub>2</sub> surfaces with three different functional groups namely -NH<sub>2</sub>, -COO<sup>-</sup> and -SH. Several wash processes were applied to remove the excess receptors from the surface after the immobilization. A Fourier transform infrared spectroscopy (FTIR) was used to control the biofilm background after each wash of the receptor coated surface which allows the optimization of the immobilization protocol. In order to test its stability the Quartz crystal microbalance (QCM) was employed and the receptor density was calculated.
Finally the optimal biolayer (silane film+ hER<sub>α</sub> receptor) was tested for measurements of 17 ß-estradiol (E2) concentration of 1µM in waterish solution. The measurement concept outlined in [L. Rebohle et al., Vacuum 83 (2009) 24-28] was applied. The whole system was investigated by PL, which exhibits two color signals, namely from the receptor and the detected E2 molecules.]]></dc:description>

<dc:description><![CDATA[In many technological processes involving liquid metals or semiconductor melts the velocity fields cannot be measured due to the lack of commercial measuring techniques for opaque melts. We present two measuring techniques which have proven recently as providing reliable velocity measurements in liquid metals, at least in the temperature range up to about 700°C: the ultrasonic Doppler Velocimetry (UDV) and the contactless inductive flow tomography (CIFT). UDV is capable of delivering velocity profiles along the ultrasonic beam with a time-resolution of about 20 Hz. CIFT is based on the flow-induced modification of some externally applied magnetic field, which is measured by some array of magnetic field sensors outside of the melt.

<dc:description><![CDATA[The sorption behavior/ retardation of actinides (uranium) in deep geological formations like clay, granite or salt is determined by the constitution of the host rock material and the presence of bioligands and microbes. To which extent can bioligands and microbes lead to a mobilisation of the respective actinyl ion?
By presenting results of our current research categorical examples for the interaction of uranium(VI) with above mentioned interaction partners are given:
-	Interaction with host rock material: the anaerobic sorption of U(VI) onto Opalinus Clay
-	Interaction with bioligands: interaction of U(VI) with the model ligand benzoic acid investigated by UV-vis spectroscopy and cryo-TRLFS
-	Interaction with microbes: interaction of U(VI) with the Äspö bacterium Pseudomonas fluorescens (HAADF-TEM measurements and uranium accumulation experiments)]]></dc:description>

<dc:source><![CDATA[Journal of Analytical Atomic Spectrometry 17(2002)4, 321-328]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[Glass treated on its surface with silver compounds and an aluminosilicate, such as ochre or clay, at higher temperatures (between 550 and 650°C) accepts a wide variety of a yellow colour. It is the aim of this study to investigate the parameters of the manufacturing process affecting the final colour of silver stained glass and to correlate them with the final colour and colour intensity. Therefore, defined mixtures of ochre and a silver compound (AgCl, AgNO<SUB>3</SUB>, Ag<SUB>2</SUB>SO<SUB>4</SUB>, Ag<SUB>3</SUB>PO<SUB>4</SUB>, Ag<SUB>2</SUB>O) were prepared and applied on soda-lime glass. The firing process was modified within the range from 563 to 630°C and glass samples were analysed after treatment with energy dispersive X-ray fluorescence analysis (EDXRF), scanning electron microscopy (SEM/EDX), transmission electron microscopy (TEM), as well as ion beam analysis (IBA) with an external beam. Within the scope of IBA simultaneous measurements using particle-induced X-ray emission (PIXE), particle-induced gamma-ray emission (PIGE), and Rutherford backscattering spectrometry (RBS) were carried out in order to obtain the thickness of the Ag-rich surface layer and the depth distribution of Ag. By means of TEM the microstructure of the silver particles was visualised. XRF results show that the lowest amount of Ag could be detected on glass samples treated with silver stain mixtures containing AgCl and Ag<SUB>2</SUB>O. A low kiln temperature (e.g. 563°C) results in a higher silver concentration at the surface and lower penetration depths. Furthermore, the results obtained with SEM/EDX at cross-sections of the glass samples could be confirmed by PIXE, PIGE, RBS, and TEM.]]></dc:description>

<dc:source><![CDATA[VIII-th INTERNATIONAL CONFERENCE "ION IMPLANTATION AND OTHER APPLICATIONS OF IONS AND ELECTRONS", 14.-17.06.2010, Kazimierz Dolny, Poland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The immediate and accurate monitoring of chemical and biological substances is essential in environmental analysis for minimizing the health risk for citizens and their exposure to pollutants. Recently, considerable attention has been focused on endocrine-disrupting compounds (EDCs), such as estrogens, which constitute a wide group of environmental pollutants, especially in drinking water.
A new concept for measuring the concentration of such organic compounds by using Si-based, integrated light sources for fluorescence analysis is presented. In that concept the analyte, estrogen in this example, is labelled with a fluorescence marker and is immobilized at the passivated surface of the light emitter by receptor molecules. 
The ion beam technology is one of the most essential steps of the light emitter fabrication. The integrated light emitters are based on a metal-oxide-semiconductor (MOS) structure. This oxide layer is implanted with Ge or rare earth ions (Gd and Tb) followed by annealing and SiON deposition. Depending on the implanted element there is a broad palette of MOS devices emitting light from the UV up to the red spectral region. The combination between Si-based integrated light emitter and this kind of biosensing opens a way to extremely small device dimensions and is of great interest for point-of-care measurements.

The current system was investigated Fourier-Transform infrared spectroscopy (FTIR), x-ray-photoelectron spectroscopy, photoluminescence (PL) and electroluminescence (EL) measurements.]]></dc:description>

<dc:description><![CDATA[Failure analysis and optimization of nanoelectronic devices require knowledge of their electrical properties. Kelvin probe force microscopy (KPFM) is a standard technique for the investigation of the surface potential. We present its applicability to locally doped semiconductors. Quantitative dopant profiling by means of KPFM is successfully shown on a conventional static random access memory (SRAM) cell and on cross-sectionally prepared Si epilayer structures by applying a recently introduced new explanation of the measured KPFM signal [1]. The presented KPFM model is also used to explain observed large conductivity differences in different Mn implanted and pulsed laser annealed Ge samples by revealing a strong variation of the Fermi level position on the µm scale in dependence on the annealing conditions [2]. 
In addition, the frequency dependence of the Kelvin bias above differently doped regions is discussed with respect to surface states and trapped charges in the thin oxide layer on top [3]. Using an active mixer, the excitation amplitude of the cantilever is almost independent of the operation frequency. As a result, KPFM measurements have to be performed at frequencies high enough so that the electrical properties of the locally doped semiconductor and not of the oxide layer are probed.

<dc:description><![CDATA[X-ray computed tomography (CT) is nowadays a well established 2D and 3D visualization technique in medicine and non-destructive testing. An increasing number of scientific and engineering problems requires three-dimensional imaging capabilities, since structures of growing complexity are seldom seizable by a cross-section only. Because CT scanning requires sampling of radiographic projections from different viewing angles around an object, typically mechanical rotation mechanisms, either for the source-detector compound or the object, are employed by common CT systems. Hence, they are quite slow and their application in the study of fast processes, such as multiphase flows or live animals, was so far impossible. 
Here we introduce a new ultrafast three-dimensional X-ray CT method based on electron beam scanning, which achieves imaging rates of 500 volume images per second. It represents an extension of a two-dimensional ultrafast electron beam CT modality presented earlier1. Although this 2D CT system reaches cross-sectional frame rates of up to 10,000 images per second, the new system is superior for the analysis of processes and moving objects, where structural changes occur in three dimensions. With an experimental study that is reported here we could demonstrate the capability of this new method to recover the structure of typical gas-solid and gas-liquid two-phase flows. Thus, ultrafast three-dimensional X-ray CT forms a practical alternative to high-speed videometry and furthermore provides non-superimposed density distributions even from opaque media.]]></dc:description>

<dc:title><![CDATA[Interaction of ephrinB2 with its receptors EphB4 and EphB6  potential impact on tumor-associated inflammation in human melanoma]]></dc:title>
<dc:source><![CDATA[21st Meeting of the European Association for Cancer Research (EACR-21), 26.-29.06.2010, Oslo, Norway]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background
Tumor-associated inflammatory cells (TAIC) are a major component of the tumor microenvironment and can contribute to both tumor progression and metastasis for instance by direct cell-cell interaction via membrane-bound proteins. Tumor cells show varying expression of Eph receptors and their ephrin ligands, which both are receptor tyrosine kinases. Eph/ephrins are hypothesized to be possible mediators of tumor-associated inflammation. The aim of our study was to analyze the distribution of ephrinB2 and its receptors EphB4 and EphB6 in inflammatory and melanoma cells and to clarify proinflammatory effects due to Eph/ephrin-mediated cell-cell contact.

Material and Methods
HL-60 promyelocytes and THP-1 monocytes, differentiated into granulocytes and macrophages, were used as a model for TAIC. Undifferentiated and differentiated cells were co-cultivated with Mel-Juso and A2058 melanoma cells. EphrinB2, EphB4 and EphB6 mRNA expression and protein synthesis was investigated using qRT-PCR and flow cytometry. Secretion of the proinflammatory cytokines IL-6 and TNF-α was analyzed using ELISA. 

Results
No alteration in gene expression of ephrinB2, EphB4 and EphB6 could be observed during differentiation of HL-60 and THP-1 cells. In contrast, protein synthesis of ephrinB2, EphB4 and EphB6 was two- to threefold higher in HL-60 granulocytes compared to HL-60 promyelocytes and HL-60 macrophages. THP-1 macrophages showed a slightly increased protein synthesis of EphB4 and EphB6 compared to THP-1 monocytes whereas ephrinB2 protein content remained constant. Co-culture of both THP-1 monocytes and macrophages with Mel-Juso cells caused a substantial increment in secretion of proinflammatory cytokines. Co-culture of both HL-60 granulocytes and THP-1 monocytes with A2058 cells did not affect cytokine secretion. By contrast, co-culture of HL-60 macrophages with A2058 cells resulted in increased IL-6 secretion whereas co-culture of THP-1 macrophages with A2058 cells resulted in increased IL-6 secretion but decreased TNF-α release. 

Conclusions
To our knowledge, mRNA expression and protein synthesis of ephrinB2, EphB4 and EphB6 was investigated for the first time in undifferentiated and differentiated HL-60 and THP-1 cells and, moreover, in Mel-Juso and A2058 melanoma cells. Co-culture of TAIC with melanoma cells resulted in proinflammatory effects. To differentiate the role of various Eph receptors and ephrin ligands in mediation of these effects after direct cell-cell contact of TAIC and melanoma cells selective inhibitors for Eph are applied in ongoing studies.]]></dc:description>

<dc:description><![CDATA[A dedicated AMS facility for depth profiling of tritium in carbon samples containing higher quantities of tritium has been installed, tested and applied for routine measurements in the Forschungszentrum Rossendorf. It is based on an SF6-insulated 100 kV tandem accelerator equipped with a thin diamond-like carbon (DLC) stripper foil of about 1 µg/cm2. The carbon samples have been cut from tiles of the inner wall of the fusion experiments ASDEX-upgrade Garching/Germany, JET Culham/GB and TFTR Princeton/USA. Depth profiles of deuterium and other light elements can be measured simultaneously using the Faraday cup at the entrance of the accelerator (SIMS mode of the facility) or in the case of very low concentrations after acceleration using a particle detector (AMS mode).

<dc:description><![CDATA[Silver nanoparticles are formed in a polystyrene film by temperature induced dissociation of an organometallic precursor dispersed in the polymer. Further heating of the sample above the polymer boiling point allows control over the fill content of the silver particles. The process is recorded in real time by spectroscopic ellipsometry. The ellipsometric data is modeled using the Maxwell-Garnett effective medium approximation. Modeling the silver component using a Drude term with a modified electronic relaxation frequency allows the particle size to be inferred by scaling the relaxation frequency with microstructural observations of the particle dimensions. The particle size can subsequently be determined during the growth process from the final radius of 7.4 nm back to 2.3 nm, at which point quantum size effects limit the effectiveness of the model.]]></dc:description>

<dc:description><![CDATA[Gallium nitride is a novel material for short wavelength (blue) optoelectronics. Our previous investigation showed that Mn doped GaN has paramagnetic or antiferromagnetic properties opening new possible applications. The high concentration of magnetic ions possibly allows for the use of such a material in magnetooptic and spintronic devices. GaMnN and GaMnMgN powders were prepared by heating mixtures of gallium and manganese powder or powders of gallium nitride and manganese in a stream of ammonia at the temperature up to 1250°C. The powders have a grain size about 1-10 µm and they contain more than 2%  of manganese by weight. Powders of doped GaN were prepared in a series of technological processes at various temperatures, ammonia flow rates and concentration of dopants in initial mixtures. Since hydrogen largely attributes to the passivation of p-dopants it plays an essential role in determination of electrical properties of these materials. Hydrogen content analysis was performed by the NRA method using the 1H(15Na,alpha gamma)12C reaction. This reaction has a sharp resonance of the cross-section at 6.385 MeV. Therefore it is possible by changing the incident 15N beam energy to measure depth distribution of hydrogen. It was found out that hydrogen concentration in our materials was below 1.5at%.]]></dc:description>

<dc:title><![CDATA[Pu recycling in a full Th-MOX PWR core: Part I - steady state analysis]]></dc:title>
<dc:source><![CDATA[Nuclear Engineering and Design 241(2011)1, 193-202]]></dc:source>

<dc:description><![CDATA[Current practice of Pu recycling in existing LWRs in the form of U-Pu mixed oxide fuel (MOX) is not efficient due to continuous Pu production from U-238. The use of Th-Pu mixed oxide (TOX) fuel will considerably improve Pu consumption rates because virtually no new Pu is generated from thorium. In this study, the feasibility of Pu recycling in a typical pressurized water reactor (PWR) fully loaded with TOX fuel is investigated. 
Detailed 3-dimensional 100% TOX and 100% MOX PWR core designs are developed. The full MOX core is considered for comparison purposes. The design stages included determination of Pu loading required to achieve 18-month fuel cycle assuming three-batch fuel management scheme, selection of poison materials, development of the core loading pattern, optimization of burnable poison loadings, evaluation of critical boron concentration requirements, estimation of reactivity coefficients, core kinetic parameters, and shutdown margin. 
The performance of the MOX and TOX cores under steady-state condition and during selected reactivity initiated accidents (RIA) is compared with that of the actual uranium oxide (UOX) PWR core. 
Part I of this paper describes the full TOX and MOX PWR core designs and reports the results of steady state analysis. The TOX core requires a slightly higher initial Pu loading than the MOX core to achieve the target fuel cycle length. However, the TOX core exhibit superior Pu incineration capabilities. 
The significantly degraded worth of control materials in Pu cores is partially addressed by the use of enriched soluble boron and B4C as a control rod absorbing material. Wet annular burnable absorber (WABA) rods are used to flatten radial power distribution. The temperature reactivity coefficients of the TOX core were found to be always negative. The TOX core has a slightly reduced, as compared to UOX core, but still sufficient shutdown margin. 
In the TOX core βeff is smaller by about a factor of two in comparison to the UOX core and even lower than that of the MOX core. The combination of small βeff and reduce control materials worth may potentially deteriorate the performance under RIA conditions and requires an additional examination. The behavior of the considered cores during the most limiting RIAs, such as rod ejection, main steam line break, and boron dilution, is further investigated and reported in Part II of the paper.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[The installation of a new 6 MV-Tandetron accelerator opens a new topic of research at FZ Dresden-Rossendorf: Accelerator mass spectrometry (AMS). The Dresden AMS facility (DREAMS) will be mainly used for measurements of the long-lived radionuclides <SUP>10</SUP>Be, <SUP>26</SUP>Al, <SUP>36</SUP>Cl, <SUP>41</SUP>Ca and <SUP>129</SUP>I (T1/2 = 0.1-15.7 Ma) in the isotopic ratio range of 10<SUP>-10</SUP>- 10<SUP>-16</SUP>. The same accelerator will be partially also used for spatial- and depth-resolved chemical analysis using ion beam techniques such as Rutherford Backscattering Spectrometry (RBS), Elastic Recoil Detection (ERD), Particle-induced X-ray and Gamma-ray emission (PIXE/PIGE) and Nuclear Reaction Analysis (NRA). Using these methods, we are able to measure nondestructively "all natural" elements, i.e. H to U; most elements with lateral, some in 3D resolution. Additionally, materials modification via high energy ion implantation is possible. 
The AMS injector consist of two Cs-sputter ion sources SO-110 with wheels for up to 200 sputter targets, a 54° electrostatic analyzer (ESA) and a 90° bouncer magnet for sequential acceleration of stable isotopes and radionuclides.  In contrast to common low-energy AMS facilities, which have mainly specialized in radiocarbon analyses (<SUP>14</SUP>C), the FZD-AMS is the first modern type facility in the EU that will run at a terminal voltage of 6 MV. The electrostatic accelerator operates with a Cockcroft-Walton type high voltage cascade for generating the terminal voltage.  The high-energy part of the system consists of a 90° analyzing magnet, a set of precise Faraday cups with energy slits for measuring the stable nuclides and stabilising the terminal voltage, a set of absorber foils for isobar suppression, a 35° ESA, and a 30° vertical magnet for suppressing interfering species. The radionuclides will be finally detected by a ΔE/E gas ionisation chamber containing four anodes.  There is a main advantage of us-ing a high-energy accelerator for mass spectrometry: The background and interfering signals, resulting from molecular ions and ions with similar masses (e.g. isobars) are nearly completely eliminated. Thus, AMS provides much lower detection limits compared to conventional mass spectrometry.  
The benefits from using AMS for radiation protection, nuclear safety, nuclear waste, radioecology, phytology, nutrition, toxicology, and pharmacology research are obvious and manifold: Smaller sample sizes, easier and faster sample preparation, higher sample throughput and the redundancy for radiochemistry la-boratories will largely reduce costs. Lower detection limits will widen applications to shorter and longer time scales and to sample types which could never been investigated before.  Especially in environmental and geosciences, the determination of long-lived cosmogenic radionuclides like <SUP>10</SUP>Be, <SUP>26</SUP>Al, and <SUP>36</SUP>Cl became more and more important within the last decades. Using these nuclides dating of suddenly occurring prehistoric mass movements, e.g. volcanic eruptions, rock valanches, tsunamis, meteor impacts, earth quakes and glacier movements, is possible. Additionally, glacier movements and data from ice cores give hints for the reconstruction of historic climate changes and providing information for the validation of climate model predicting future changes. Taking the advantage of location into account DREAMS will soon also focus on applications of radionuclides of anthropogenic origin such as plutonium isotopes and <SUP>129</SUP>I. 
Investment and maintenance costs of a high-energy AMS facility are much higher compared to e.g. methods determining radionuclides via their decay. All methods including AMS need sophisticated radiochemical separation procedures. However, for several nuclides the requirements with respect to the purity of the final sample to be measured are much lower for AMS. As it is the case for most destructive analytical methods AMS chemical sample preparation takes much longer and is more expensive that the actual measurement, which takes about 10 - 60 min.]]></dc:description>

<dc:description><![CDATA[Single-phase vanadium dioxide films grown on (0001) sapphire and (001) silicon substrates show very different insulator-metal electronic transition. A detailed description of the growth mechanisms and the substrate-film interaction is given, and the characteristics of the electronic transition are described by the morphology and grain boundary structure. (Tri-)epitaxy-stabilized columnar growth of VO2 takes place on the sapphire substrate, while on silicon the expected Zone II growth is identified. We have found that in the case of the Si substrate the reasons for the broader hysteresis and the lower switching amplitude are the higher average oxygen vacancy concentration and the VxSiyO built up in the grain boundaries. These phenomena are the result of the material transport between the silicon substrate and the growing film.]]></dc:description>

<dc:description><![CDATA[Experimental investigations revealed that both the impurity Cu and the alloying element Ni may contribute to hardening and embrittlement of reactor pressure vessel (RPV) steels during the irradiation by fast neutrons. The irradiation-induced supersaturation of vacancies and self-interstitials amplifies the diffusion of the foreign atoms in bcc-Fe and causes the formation of nanosized Cu- or Ni-rich clusters which act as obstacles to dislocation motion within the grains of the polycrystalline matrix. The concentration of Cu in RPV steels is typically higher than its solid solubility and, therefore, irradiation-enhanced  formation of Cu-rich precipitates is observed. Measurements showed that these clusters may not only consist of pure Cu but also include vacancies [1]. On the other hand, the Ni concentration is typically below its solubility limit. That means, any formation of Ni-rich clusters as found in [2] for neutron-irradiated binary Fe-Ni alloys is essentially irradiation-induced. Obviously, these clusters must contain additional species in order to be stable. Small-angle neutron scattering analysis [2] indicated that vacancies could be the other constituent.
In the present work atomistic computer simulations using the ternary Fe-Cu-Ni interatomic potential by Bonny et al. [3] are employed to investigate the thermodynamics of Cu-vacancy and Ni-vacancy precipitates in bcc-Fe. The nucleation free energy of the clusters is determined by the energy and the entropy change due to precipitation using isolated (diluted) Cu and Ni atoms as well as vacancies as the reference. In agreement with indications from measurements the nanoclusters are assumed to have the bcc structure of the iron matrix. The binding energy of the most stable cluster configurations is calculated by simulated annealing within the framework of on-lattice Metropolis Monte Carlo simulations and by subsequent relaxation using off-lattice molecular dynamics calculations.

<dc:title><![CDATA[Ultrasensitive Bestimmung von Radionukliden Mittels Beschleunigermassenspektrometrie bei DREAMS am Beispiel von <sup>36</sup>Cl]]></dc:title>
<dc:source><![CDATA[7. Workshop RCA, 10.-11.06.2013, Dresden, Deutschland]]></dc:source>
<dc:date>2013</dc:date>
<dc:description><![CDATA[Beschleunigermassenspektrometrie (AMS - Accelerator Mass Spectrometry) ist eine hochsensitive Methode zur Bestimmung der Häufigkeit von Radioisotopen. Dabei werden Radionuklide immer relativ zu den stabilen Isotopen des jeweiligen Elements gemessen. Da bei der AMS radioaktive Atome nicht durch ihren Zerfall detektiert werden, sondern direkt gezählt werden, eignet sich die Methode in erster Linie für langlebige Radionuklide (t<sub>1/2</sub> > 100 a). Dabei können je nach Element Isotopenverhältnisse von 10<sup>-15</sup>-10<sup>-16</sup> (entspricht nBq) gemessen werden, wobei die Messzeit ca. 1 h pro Probe beträgt. Im Wesentlichen besteht eine AMS-Anlage aus einer Ionenquelle (üblicherweise Cs-Ionensputterquelle) zur Extraktion negativer Ionen aus dem Probenmaterial (< 10 mg), zwei Massenspekrometern (Injektormagnet und Analysiermagnet) zum Filtern der Ionen nach ihrer Energie, ihrem Impuls und Ladungszustand, einem Beschleuniger der die Ionen auf die für die finale Separation notwendigen Energien (MeV) beschleunigt und durch das sogenannte „Stripping“ für eine totale Unterdrückung des molekularen Isobarenhintergrundes sorgt und einem Detektor zum Zählen der Radioisotope bzw. Faraday-Cups zur Messung des Stromes der Stabilisotope. 

Die AMS-Anlage DREAMS (DREsden AMS) ist seit August 2011 in Betrieb [1]. Momentan werden bei DREAMS Routinemessungen der Nuklide <sup>10</sup>Be, <sup>26</sup>Al und <sup>41</sup>Ca durchgeführt [2]. Bei den volatilen Element Cl und I werden Präzisionsmessungen noch durch Langzeit- und Probe-zu-Probe-Kontaminationseffekte in der Ionenquelle verhindert [3]. Kooperationen mit der TU Bergakademie Freiberg einerseits und dem UFZ Leipzig (Helmholtz-Zentrum für Umweltforschung) andererseits bei denen Proben aus der Salar de Uyuni (Salzwüste in Bolivien) und von unterirdischen Wasserläufen im Oman untersucht wurden, haben gezeigt, dass die Bestimmung von <sup>36</sup>Cl-Konzentrationen dennoch auf einem Level von einigen 100 nBq zurzeit schon möglich ist. Die Entwicklung einer neuen Ionenquelle für volatile Elemente, die in ersten Versuchen vielversprechende Ergebnisse geliefert hat, wird noch präzisere AMS-Messungen von <sup>36</sup>Cl bei DREAMS ermöglichen.

<dc:description><![CDATA[In this talk I will present an overview of the activities at the Forschungszentrum Dresden-Rossendorf (FZD) focusing on laser ion acceleration, x-ray generation via Thomson scattering and medical beam line design for tumor therapy with laser-driven particle beams.
Optimization and precise control of the properties of laser-driven radiation sources using large-scale realistic simulations and direct comparison to experiment play a key role in the research program at FZD.
I will show some recent results obtained at FZD and give an outlook on future work, with an emphasis on the development of new simulation tools.]]></dc:description>

<dc:title><![CDATA[A comprehensive study of the p-type conductivity formation in radio frequency magnetron sputtering grown arsenic-doped ZnO film]]></dc:title>
<dc:source><![CDATA[6th International Workshop on Zinc Oxide and Related Materials, 05.-07.08.2010, Changchun, China]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[As-doped ZnO films were grown by the radio frequency magnetron sputtering method at different substrate temperature TS. For each of the TSs, the average carrier concentration and mobility were obtained from samples grown by eight independent runs of growth through the Hall measurement.  ZnO films grown on SiO2, Si and glass exhibited similar conductivity dependence on TS.  As a typical example shown in the figure illustrating the carrier concentration of ZnO:As/SiO2, n-type high resistive films were yielded at low TS (i.e. 200°C).  Those grown at TS=350°C and 400°C were p-type, though had large deviations from individual runs of growth. Reproducible p-type films having h~6x10<sup>17</sup>cm-3 and µ~6 cm2V-1s-1 were fabricated at high enough TS of 450°C.  Conversion of the n-type ZnO:As film grown at TS=200°C to p-type film (p~10<sup>17</sup>cm-3) was observed upon the 450°C post-growth annealing in Ar.  
	The ZnO:As films grown at different TSs were studied by X-ray photoelectron spectroscopy (XPS), photoluminescence (PL), positron annihilation spectroscopy (PAS) and nuclear reaction analysis (NRA).  The XPS and the 10K PL results showed that majority of the As-atoms occupied the Zn-site of the lattice and the As-related acceptor had an activation energy Ea=155 meV. The correlated increase of S-parameter (obtained from the PAS study) showed that the p-type conductivity was associated with the Vzn-related defect and/or its increased open volume. These results were in consistent with Limijumnong et als AsZn-2VZn shallow acceptor model [Phys. Rev. Lett. 92, 155504 (2004)], which proposed an Ea=0.15 eV and a VZn volume increase due to atomic relaxation. An anti-correlation between the H-density and the p-type conductivity was also observed in the NRA study.  Our results thus suggested that the p-type conductivity was associated with the thermally induced AsZn-2VZn shallow acceptor formation and the H-donor reduction.

<dc:description><![CDATA[At the bremsstrahlung facility of the ELBE accelerator there exists the possibility to investigate dipole strength distributions up to the neutronseparation energies with photon energies up to 18 MeV. The facility and various results for nuclides measured during recent years will be presented. One example is the study of 86Kr that complements a systematic study of stable isotones at the shell closure of neutron number N = 50. As a special feature, a high-pressure gas target was used in this experiment. The other presented example is an experiment on 136Ba. GEANT4 simulations were performed to detremine the non-nuclear background that has to be removed from the measured spectra. This opens up the possibility to take into account also the strength of unresolved transitions. Simulations of gamma-ray cascades were carried out that consider the transitions from states in the quasicontinuum and allow us to estimate their branching ratios. As a result, the photoabsorption cross sections obtained from corrected intensities of ground-state transitions are combined with existing data from (gamma,n) experiments and are compared with theoretical predictions.]]></dc:description>

<dc:description><![CDATA[HADES is a second generation experiment designed to study dielectron production in proton, pion and heavy ion induced reactions at the GSI accelerator facility in Darmstadt. The physics programme of HADES is focused on in-medium properties of the light vector mesons. In this contribution we discuss relevance of dielectron spectroscopy to the problem of hadron mass origin. We present status of the HADES experiment, demonstrate ists capability to identify rare dielectron signal and show first experimental results obtained from C+C reations at 2 AGeV.]]></dc:description>

<dc:date>1996</dc:date>
<dc:description><![CDATA[Siliconoxynitride layers with thicknesses between 5 and 10 nm were grown on (100) oriented silicon by rapid thermal processing (RTP) using either N20 or NH3 as nitridant. In order to study the trapping behaviour at the interface and in die insulator bulk, capacitance-voltage (CV) and current-voltage (IV) measurements have been performed combined with different magnitudes of Fowler-Nordheim stress. In addition, Deep Level Transient Spectroscopy (DLTS) has been applied for interface state detection. Auger Electron Spectroscopy (AES) has been used to obtain depth profiles for Si, N, 0 and C. The deconvolution of die AES signal displays significant peak contributions related to intermedium oxidation states. Nuclear Reaction Analysis (NRA) was successfully applied for hydrogen detection in buried SiOXNY thin films.]]></dc:description>

<dc:description><![CDATA[At the Rossendorf nuclear microprobe facility, a beam of protons with MeV energy was used to analyse ancient human bones of the Merowingian period (6-8th
century AD), Emitted X-rays were detected to determine the elemental composition of the bones and to estimate the influence of the burial environment on the
elemental content of the skeletons, In cross sections of human femora, a different behaviour of the radial distributions of the main and trace elements like P, Ca, Mn,
Fe, Zn, Br, and Sr was observed using lateral-resolved mu PIXE. This result indicates post mortem mineral exchange processes and diagenetic alteration during
burial of bone tissue in soil.]]></dc:description>

<dc:description><![CDATA[We report on high-field magnetization, specific-heat and  electron spin resonance (ESR) studies of the quasi-two-dimensional spin-1/2 Heisenberg antiferromagnet [Cu(pyz)<sub>2</sub>(HF<sub>2</sub>)]PF<sub>6</sub>. The frequency-field diagram of ESR modes below T<sub>N</sub> \approx 4.38 K is described in the frame of the mean-field theory.  The obtained results allowed us to determine the anisotropy/exchange interaction ratio, A/J = 0.003, and the upper limit for the inter/intra-plane exchange-interaction ratio, J'/J = 1/16. It is argued that despite of onset of 3D long-range magnetic ordering the magnetic properties of this material (including high-magnetic-field magnetization and nonmonotonic field dependence of the Neel temperature) are strongly affected by two-dimensional spin correlations.]]></dc:description>

<dc:source><![CDATA[Int. Conf. "Nuclear Energy for New Europe", 06.09.-09.10.2010, Portoz, Slovenien]]></dc:source>

<dc:description><![CDATA[Bubble condensation in sub-cooled water is a complex process, to which various phenomena contribute. Since the condensation rate depends on the interfacial area density, bubble size distribution changes caused by breakup and coalescence play a crucial role.
Experiments on steam bubble condensation in vertical co-current steam/water flows have been carried out in a 8m long vertical DN200 pipe. Steam is injected into the pipe and the development of the bubbly flow is measured at different distances to the injection using a wire mesh sensor.

<dc:description><![CDATA[Bubble condensation in sub-cooled water is a complex process, to which various phenomena contribute. Since the condensation rate depends on the interfacial area density, bubble size distribution changes caused by breakup and coalescence play a crucial role.
Experiments on steam bubble condensation in vertical co-current steam/water flows have been carried out in a 8m long vertical DN200 pipe. Steam is injected into the pipe and the development of the bubbly flow is measured at different distances to the injection using a wire mesh sensor. By varying the steam nozzle diameter the initial bubble size can be influenced. Larger bubbles come along with a lower interfacial area density and therefore condensate slower. Steam pressures between 1-2 MPa and sub-cooling temperatures from 2 to 6 K were applied. Due to the drop of hydrostatic pressure along the pipe, the saturation temperature falls towards the upper pipe end. This affects the sub-cooling temperature and can even cause re-evaporation in the upper part of the test section. The experimental configurations are simulated with the CFD code CFX using an extended MUSIG approach, which includes the bubble shrinking or growth due to condensation or re-evaporation.

<dc:date>1998</dc:date>
<dc:description><![CDATA[The enrichment of F on Antarctic meteorites is the result of their exposure to the atmosphere, and its measurement allows a subdivision of the terrestrial age into a
duration of exposure on the ice and the time a meteorite was enclosed by the ice. In many cases, the periods of surface exposure are only small fractions of the
terrestrial ages of meteorites collected in Antarctica. The enrichment of F on the surfaces of Antarctic achondrites was investigated by means of nuclear reaction
analysis (NRA): scanning proton beams with an energy of 2.7 and 3.4 MeV were used to induce the reactions F-19(p,alpha gamma)160 and
F-19(p,p'gamma)F-19, respectively. Gamma signals proportional to the F content were measured. The following Antarctic achondrites were investigated: Martian
meteorite ALH 84001; diogenite ALHA77256; the eucrites ALHA81011 and ALHA78132; and in addition, the H5 chondrite ALHA79025. For ALH 84001, our
data indicate a period of exposure on the ice of <500 years. Thus, this specimen was enclosed in the ice >95% of its terrestrial age of 13 000 years.]]></dc:description>

<dc:source><![CDATA[Vacuum 84(2010), 913-919]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Near equiatomic and Ti-rich NiTi polycrystalline films have been deposited by magnetron co-sputtering using a chamber installed at a synchrotron radiation beamline. The in situ X-ray diffraction studies enabled the identification of different steps of the structural evolution during film processing. 
The depositions on a 140 nm amorphous SiO2 buffer layer heated at 520°C (without applying bias voltage, Vb, to the substrate) led to a preferential growth of <100> oriented grains of the NiTi B2 phase from the beginning of film growth until the end of the deposition. 
Films exhibiting a preferential growthof <110> oriented grains of the NiTi B2 phase from the beginning of the deposition were obtained (without and with a Vb of - 45 V) by using a TiN coating with a topmost layer formed by <111> oriented grains. Those trends have been observed for the growth of near equiatomic (~50.0 at.% TiNi) and Ti-rich (~50.8 at.% TiNi) NiTi films.
Additionally, an ion gun had been commissioned, which allows ion bombardment during sputter deposition or post-deposition ion irradiation. In this first series of experiments, a NiTi film was irradiated with He ions after deposition (without exposing the film to the atmosphere, i.e., avoiding surface oxide formation), thus modifying deliberately the microstructure of the film locally.]]></dc:description>

<dc:description><![CDATA[The first application of a Sonogashira cross-coupling reaction in <SUP>18</SUP>F chemistry has been developed. The reaction was exemplified by the cross-coupling of terminal alkynes (ethynylcyclopentyl carbinol  6, 17alpha-ethynyl-3,17beta-estradiol  7 and 17alpha-ethynyl-3-methoxy-3,17beta-estradiol  8) with 4-[<SUP>18</SUP>F]fluoroiodobenzene. 4,4'-Diiododiaryliodonium salts were used as precursors for the synthesis of 4-[<SUP>18</SUP>F]fluoroiodobenzene, enabling the convenient access to 4-[<SUP>18</SUP>F]fluoroiodobenzene in 13-70 % yield using conventional heating or microwave activation. The Sonogashira cross-coupling of 4-[<SUP>18</SUP>F]fluoroiodobenzene with terminal alkynes gave the corresponding 4-[<SUP>18</SUP>F]fluorophenylethynyl-substituted compounds [<SUP>18</SUP>F]-9, [<SUP>18</SUP>F]-10 and [<SUP>18</SUP>F]-13 in yields up to 88% within 20 min starting from 4-[<SUP>18</SUP>F]fluoroiodobenzene.]]></dc:description>

<dc:source><![CDATA[13. Jahrestagung der Gesellschaft für Biologische Strahlenforschung GBS, 01.-02.09.2010, Hamburg, Deutschland]]></dc:source>

<dc:description><![CDATA[Background: The novel technology of laser particle acceleration, which promises ion radiotherapy accelerators of compact size and reasonable costs, generates ultra-short pulsed particle beams (~ 100 fs) with very high pulse dose rate (more than 1012 Gy/min). The development of this new technology for radiotherapy application is the aim of the joint research project onCOOPtics  High intensity lasers for radiooncology. One important step before potential medical application is the radiobiological characterization of this new radiation quality starting with in vitro cell experiments. 

Material and Methods: Cell irradiations have been performed with protons generated at the 150 TW laser system Draco installed at the FZD. Before starting irradiation experiments the laser particle accelerator had to be optimized with respect to intensity, energy distribution, spot size, stability and reliability of the proton beam. Furthermore, beam filtering and transport to an in-air irradiation site and a dosimetry system were developed and realised. For a precise dose measurement, low energy protons were filtered out by a permanent magnet system. At cell irradiation site the proton beam possessed an energy spectrum of 6 to 18 MeV with a maximum at 7 MeV resulting in a minimal penetration depth in water of approximately 500 µm. To avoid stopping of protons within the bottom of the cell culture vessel or the cell monolayer, dedicated material for cell cultivation and irradiation had to be established to minimize material on the proton path. Cells of the radiosensitive tumour cell line SKX were seeded at thin biofilm (50 µm thickness) in place of conventional cultivation vessels. To quantify the irradiation damage, residual DNA double strand breaks were detected using the immunofluorescence H2AX/53BP1 staining technique 24 h after irradiation, optimized for the special cell carrier material. Cell samples were irradiated with three different doses applied by different proton pulse numbers and controlled by online dose measurement. As online dosimetry system an ionization chamber was used, cross-calibrated against Gafchromic EBT radiochromic films and a Faraday cup to provide precise dose determination at the cell site. 

Results: The successful in vitro cell irradiation by laser-accelerated protons represents an important milestone on the long term development of laser ion acceleration for clinical radiotherapy. The laser accelerator generated a stable and reproducible proton beam over the whole experiment time. The measurement of the ionization chamber as online dosimeter showed a stable mean dose per pulse of (0.1370.039) Gy during all irradiations. The EBT films verified a homogeneous dose distribution at the cell location. The irradiated tumour cells demonstrated a clear trend in the number of DNA double-strand breaks in accordance with delivered dose.

Conclusion: Systematic cell irradiation experiments with laser-accelerated protons has been started determining dose-effect curves for both tumour and normal tissue cell lines and also including the cell surviving assay as second biological endpoint. In addition to the experiments with laser-accelerated proton pulses reference cell irradiations are performed using a continuous proton beam at a conventional tandem accelerator.

<dc:description><![CDATA[The nELBE beamline at Forschungszentrum Dresden-Rossendorf (FZD) provides intense neutron beams by stopping a primary electron beam in a liquid lead radiator and producing then neutrons by bremsstrahlung photons through (gamma,n) reactions. To increase the neutron yield through the electron energy enhancement (from the current 40 MeV limit up to 50 MeV), to optimize the neutron/photon ratio and to minimize several source of background at the present time, a new neutron beamline with a new, larger experimental room has been designed. Extensive simulations with the particle interaction and transport code FLUKA have been performed to assess all the shielding aspects of the design.

<dc:description><![CDATA[The design and synthesis of anion receptors of technical and biochemical significance is receiving more and more attention.<SUP>1-8</SUP> Currently, effective binding and selective phase transfer of the oxoanions pertechnetate and perrhenate is of considerable interest from different point of view. Due to its long half-life and environmental mobility, the radioactive pertechnetate is one of the most hazardous contaminants. In this context, effective and selective separation processes are of utmost importance.<SUP>9-12</SUP> On the other hand, there are some emerging possibilities for the application of the radiochemically active oxoanions pertechnetate and perrhenate in nuclear medicine.<SUP>13,14</SUP> The most commonly used isotope in diagnostic nuclear medicine <SUP>99m</SUP>Tc is readily available from a <SUP>99</SUP>Mo/<SUP>99m</SUP>Tc generator system.<SUP>15-19</SUP> Likewise, the b-emitting <SUP>188</SUP>Re  discussed as one of the most interesting radionuclides for specific therapeutic applications  is conveniently produced by a <SUP>188</SUP>W/<SUP>188</SUP>Re generator.<SUP>20-22</SUP> In both cases the radionuclides are available as oxoanions in isotonic solution, and it appears highly desirable to directly complex <SUP>99m</SUP>TcO<SUB>4</SUB><SUP>-</SUP> and <SUP>188</SUP>ReO<SUB>4</SUB><SUP>-</SUP> as they exist in the generator eluate itself. But, the binding of such large, lowly charged anions is a difficult venture. The enthalpic contribution for complexation is rather small. Hence, host compounds being capable to encapsulate these oxoanions are of great interest. 
For both directions discussed above, some different requirements have to be fulfilled for the design of ligands. The essential properties of ligands serving as extractants and imaging/therapeutic agents are summarized in Table 1.]]></dc:description>

<dc:title><![CDATA[Multiphase flow measurement techniques in industrial safety analysis]]></dc:title>
<dc:source><![CDATA[6th Dresden Symposium, "HAZARDS DETECTION AND MANAGEMENT", 20.-24.09.2010, Dresden, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Multiphase flows play a major role in many industrial fields, such as in chemical and mineral oil industry and energy power production. Industrial processes run at high pressures and temperatures and involve hazardous materials, such as toxic chemicals or radioactive products. Hence, they must be operated in a safe way under all circumstances, not only in the operational plant mode but also for accident scenarios. Therefore the Institute of Safety Research at Forschungszentrum Dresden-Rossendorf (FZD) spends great effort in the investigation of multiphase flow behavior in industrial plants under such conditions. Understanding the physics of multiphase processes and flows requires special instrumentation of industrial plant components as well as dedicated test facilities.

The expertise at FZD covers the identification of different phases and temperatures employing measurement techniques for permittivity and conductivity as well as ultrafast electron beam X-ray tomography. Many measurement systems, like wire-mesh sensors, needle probes and flow microscopes have been developed and are continuously improved. Especially the existing expertise is the basis for the research on new multiphase measurement technologies, for example autonomous sensors but also a multi-phase flow meter and a filling level sensor. 

The poster describes some of the available measurement technologies and outlines future developments.]]></dc:description>

<dc:description><![CDATA[A monitoring system based on adaptive heat balances has been developed for early fault detection in exothermic reactions. Its efficiency could experimentally be proven for a homogeneous esterification reaction in the laboratory reactor and pilot plant scale.
Experiments under normal and several faulty conditions were carried out in different reactor scales to prove the adaptation of the monitoring technique to various scales of chemical batch reactors. Results of the on-line testing in the pilot plant showed that the monitoring system was able to recognise undesired faults correctly.]]></dc:description>

<dc:description><![CDATA[The reaction p d -> d phi p_{sp} is studied within the Bethe-Salpeter formalism. Under special kinematical conditions (slow backward spectator proton p_{sp} and fast forward deuteron) relevant for forthcoming experiments at COSY, the cross section and a set of polarization observables factorize in the contribution of the pure subprocess p n -> d phi and a contribution stemming from deuteron quantities and kinematical factors. This provides a theoretical basis for studying threshold-near processes at quasi-free neutrons.]]></dc:description>

<dc:description><![CDATA[We present a new theoretical understanding of and selected results from experiments performed in 2009 at the TRIDENT laser at Los Alamos National lab. Those experiments yielded the wolrd's highest proton energies from laser-solid interaction and were based on novel flat-top copper cone targets. Simulations show that a new mechanism of laser-plasma interaction was responsible for the observed high proton energies and suggest that an optimization of the cone geometry may further enhance the achievable proton energies.]]></dc:description>

<dc:description><![CDATA[A novel technique for the determination of the thermodynamic and kinetic parameters of the Grignard reagent formation is described. Instead of operating under the spontaneous exothermic initiation of Grignard reactions, the calorimetric measurement was carried out in a closed reactor pressure vessel. In that way, the increase of the reactor temperature and the pressure can be used for detecting the initiation of the Grignard-reagent formation as shown by comparison with the on-line profiles of the concentration of the Grignard reagent measured by FTIR-spectroscopy simultaneously. Results showed that the molar reaction enthalpy of a Grignard reagent could be determined by a closed reactor vessel more accurately than under reflux conditions.]]></dc:description>

<dc:description><![CDATA[The catalytic hydrogenation of aromatic nitro compounds is a complex exothermic process influenced by the competing effects of the mass transfer and the kinetics. In reaction calorimeters, several methods were applied to determine the parameters of kinetics and mass transfer under different process conditions. It was found that a bad quality of the aromatic nitro compound and disadvantageous process conditions can cause an accumulation of intermediates which probably deactivate the catalyst and lead to low reaction rates.]]></dc:description>

<dc:description><![CDATA[The 14N(p,g)15O reaction is the bottleneck of the carbon-nitrogen-oxygen (CNO) cycle, thus determining its speed. The precise knowledge of its cross section is necessary to address the recently discovered discrepancy for elemental abundances in the standard solar model, the so-called solar abundance problem. Several experimental efforts are underway to improve the precision, among them lifetime measurements of excited states in the 15O compound nucleus. The seminar talk will report on a different approach, namely a direct cross section measurement at comparatively high energy, 0.5-1.5 MeV, recently performed at the Dresden Tandetron.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The project ECOSTAR (acronym for ex-vessel core melt stabilization research) involves in total 17 orgnizations from five European countries. The objective of the project is to demonstrate the technical feasibility of core melt mitigation measures outside the reactor pressure vessel (RPV) as well as the validation of a selected set of codes in order to provide the necessary input for the definition of a convincing safety concept to control corium melts for both existing and future reactors.
The ECOSTAR projects is focused on three key phenomena for ex-vessel mitigation measures, namely melt release from RPV, ex-vessel corium transport and long-term corium stabilization. The extensive work program covers different scenarios and consists of a large number of experiments with both simulant and real materials, code development and validation as well as analytical activities.
This paper presents the progress of work per end of the year 2001 and the results obtained since the launch of the project. ]]></dc:description>

<dc:description><![CDATA[The solidification process and the resulting microstructure of Nd-Fe-B alloys in consideration of melt convection has been investigated experimentally with a specially designed floating-zone arrangement. A controlled influence on the melt flow is possible via tailored magnetic fields which enable enhancement or suppression of the melt convection. A specially designed magnetic two-phase stirrer offers a strong influence on the melt flow in the floating-zone facility. As a result, the microstructure pattern, mainly the volume fraction and grain size of the a-Fe phase, vary strongly with the strength of the internal flow motion. The melt flow is studied numerically under the additional effect of the two-phase stirrer taking into account the coupled heat and fluid flow fields. The electromagnetically driven flow during the inductive heating turned out to be of strong influence on the resulting microstructure.

<dc:description><![CDATA[The influence of melt rotation on the microstructure formation of Nd-Fe-B alloys, mainly  the  volume fraction and grain size of the a-Fe phase, has been investigated using the electromagnetic levitation technique which allows the in-situ measurement of the solidification kinetics containerlessly. Samples were subjected to a strong rotation during levitation and compared to fixed samples without additional sample rotation in the levitation facility. Additionally, experiments have been carried out where specially sealed samples were subjected to a well-defined forced rotation. A distinct reduction of the a-Fe volume fraction in samples with strong rotation was observed by measuring the magnetic moment in a vibrating sample magnetometer (VSM). The influence of cooling rate and undercooling level on microstructure formation and phase distribution has been investigated as well. The melt flow in a levitated droplet is studied numerically under the additional effect of a global sample rotation which may give a strong suppression of internal motions.]]></dc:description>

<dc:description><![CDATA[To protect the health of the population, knowledge is necessary about the transfer of radioactive heavy metals, like uranium, via the food chain soil-water-plant-animal-human. The overall process of uptake of heavy elements into plant tissues from contaminated soils is quantified using the soil-to-plant transfer factor (TF). The transfer factor of uranium for lupine and dandelion is in the range of  10-2  to 10-3. To obtain a more mechanistic understanding of the uptake of heavy metals in plants  knowledge about the  individual physical-chemical processes is  needed. This study focuses on the determination of uranium speciation after uptake of uranium by plants (lupine, dandelions, lamb¢s lettuce). For the first time, laser-induced fluorescence spectroscopy and X-ray absorption spectroscopy were used to determine the chemical speciation of uranium in plants. Information on the spatial distribution of uranium in the plant was achieved by scanning electron microscopy, coupled with energy-dispersive X-ray microanalysis. Differences were detected between the uranium speciation in the initial solutions (hydrophonic and pore water of soil) and inside the plants. The oxidation state of uranium remained hexavalent after the uptake. The chemical speciation of uranium was identical in the roots, shoot axis, and leaves and was independent of the various investigated plants. First results are  reported concerning the speciation of uranium in cell sap and solid cell components after separation. Spectroscopic data of relevant model compounds (e.g. sugar phosphates, inorganic phosphates, carboxylic acids, proteins) are compared with the uranium complexes in the different compartments of the plants.The results indicate that the uranium is predominantly bound to phosphoryl groups but in dependence on the experimental conditions the formation of uranium carboxylate complexes cannot be excluded.]]></dc:description>

<dc:description><![CDATA[A new scheme to efficiently accelerate protons by a single linear polarized high-intensity ultrashort laser pulse using multiple ultrathin foils is proposed. The foils are stacked at a spacing comparable to their thickness and subsequently irradiated by the same laser pulse. The foil thicknesses are chosen such that the laser light pressure can displace all electrons out of the foil. The authors present a simple, yet precise dynamical model of the acceleration process from which both optimum foil thickness and spacing can be derived. Extensive two-dimensional (2D) particle-in-cell simulations verify the model predictions and suggest an enhancement of the maximum proton kinetic energy by 30% for the two-foil case compared to a single foil.]]></dc:description>

<dc:description><![CDATA[The magnetoconductance of an open carbon nanotube (CNT)-quantum wire was measured in pulsed magnetic fields. At low temperatures, we find a peculiar split magnetoconductance peak close to the chargeneutrality point. Our analysis of the data reveals that this splitting is intimately connected to the spin-orbit interaction and the tube chirality. Band-structure calculations suggest that the current in the peak regions is highly spin polarized, which calls for application in future CNT-based spintronic devices.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[A superconducting electron linear accelerator of high brilliance and low emittance has been constructed in the Forschungszentrum Rossendorf in order to deliver cw electron beams with a maximum average current of 1 mA. The accelerator will be used to produce different kinds of secondary radiation, neutrons and positrons. Bremsstrahlung produced at ELBE will be used for nuclear-structure and nuclear-astrophysics experiments employing photon-induced reactions such as (y,y) (nuclear-resonance-fluorescence), (y,n), (y,p) (nuclear photo effect) and photon-induced fission. These experiments will be carried out with electron energies up to 20 MeV at a specially designed bremsstrahlung facility. In order to optimize the design of components of the bremsstrahlung facility and to reduce background radiation, simulations using the code GEANT were performed. We describe the main elements of the bremsstrahlung facility, such as the thin water-cooled radiator, the beam hardener, the photon beam collimator, the HPGe-detector setup. Furthermore, we present a comparison of simulations with measurements and report on first experiments with the new facility.]]></dc:description>

<dc:source><![CDATA[10th Int. Conf. on Computer Simulations of Radiation Effects in Solids (COSIRES 2010), 19.-23.07.2010, Krakow, Poland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The reliability and predictability of classical molecular dynamics simulations is based on the precision of the interatomic potential used. Because Si has such a great technological importance there is a clear need for more accurate potentials. Recently, a new bond-order potential has been developed [1] by modifying the well-known analytical form given by Tersoff. It has been shown that this potential can reproduce many structural and thermodynamic properties of diamond-structure Si, such as the elastic constants and the melting characteristics, and it is able to determine the cohesive energy and the lattice constants of other solid phases reasonably well [1,2]. Furthermore, the potential yields rather correct data on structure and thermodynamics of liquid and amorphous Si. [2]. 
In the present work the new bond-order potential is applied to investigate point defect energetics and kinetics as well as solid phase epitaxial recrystallization of amorphous Si. The structure and the formation energy of the most stable configurations of vacancies and self-interstitials are determined. The migration of point defects is simulated and the characteristic migration pathways are identified. A more comprehensive study on preparation and properties of amorphous Si than in [2] is performed, and the results are compared with available experimental data. Solid phase epitaxial recrystallization is simulated at different temperatures and the recrystallization rate is determined. The results on point defect properties and solid phase epitaxial recrystallization are compared with those obtained by the Stillinger-Weber and the Tersoff potential as well as with experimental data and results of first principle calculations. Finally, a comparison is made with available results determined by two other bond-order potentials which have been recently developed [3-6].

<dc:source><![CDATA[23rd International Free Electron Laser Conference, 20.-24.08.2001, Darmstadt, Deutschland<br>Proceedings of FEL 2001, II-19]]></dc:source>

<dc:description><![CDATA[The ELBE project is intended to produce a wide spectrum of different radiation and neutrons, especially coherent light in the medium and far infrared by means of a free electron laser. The driver of the radiation source is a super-conducting electron linear accelerator designed for a wide range of beam parameters in order to satisfy the various requirements.
Recently, the forst cryostat containing two nine-cell niobium standing wave rf cavities for an acceleration up to 20 MeV has been put into operation and has been cooled down. For the first time, an accelerated electron beam has been produced successfully.
The helium cooling for the cryostat working at 1.8 K, the electron beam injector, the radio frequency system, beam control and beam diagnostics operate very reliably. In the paper the results of the beam parameter measurements and the experiences gained in the first operation period will be presented.

<dc:description><![CDATA[The Rossendorf superconducting Electron Linac of high Brilliance and low Emittance (ELBE) delivers an 40 MeV, 1 mA cw-beam for different applications such as bremsstrahlung production, electron channeling, free-electron lasers or secondary particle beam generation. In this energy region in case of collisions of the electron beam with the pipe nearly all beam power will be deposited into the pipe material. Therefore a reliable beam loss monitoring is essential for machine protection at ELBE. Different systems basing on photo multipliers, compton diodes and long ionisazion chambers were studied. The pros and cons of the different systems will be discussed. Ionisazion chambers based on air-isolated RF cables installed some cm away parallel to the beam line turned out to be the optimal solution. The beam shut-off threshold was adjusted to 1 µC integral charge loss during a 100 ms time interval. Due to the favourable geometry the monitor sensitivity varies less than +/- 50 % along the beam line (different shielding conditions).]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Traveling-wave Thomson scattering is a novel interaction design that allows circumventing the Rayleigh limit in optical undulators, which is interesting for possible realizations of Thomson scattering sources with photon yields per pulse that are orders of magnitudes beyond current designs. The resulting radiation reaction could even be strong enough for driving an FEL instability. Here we present details on how a Traveling-wave setup has to be implemented in experiment. An emphasis is put on the use of varied-line spacing (VLS) gratings for spatio-temporal beam shaping at large interaction angles to achieve optimal overlap. At the FZD we are using the high-power laser system DRACO (250TW) to realize a Thomson source with electrons from the linear accelerator ELBE or laser-plasma accelerated electrons. We present the current status and further progress towards a head-on Thomson source and a Traveling-Wave Thomson scattering source aiming for high photon yields per pulse.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[A one-dimensional code DYN1D-MSR for transient analysis of Molten Salt Reactors  MSR was developed in FZR. The code is based on the well know three-dimensional code DYN3D. The neutron kinetics routines for axial direction calculation from DYN3D are combined with new models of delayed neutrons production and thermal-hydraulic. The results from the Molten salt Reactor Experiment were used to validate the code. After the successful validation several transients typical for the liquid fuel system were analyzed using the design data of the Molten Salt Breeder Reactor. The results of all transients (overcooling of fuel at core inlet, reactivity insertion, and fuel pump coast-down) have shown that the dynamic behavior of MSR is stable when the coefficients of thermal feedback are negative.]]></dc:description>

<dc:source><![CDATA[Journal of Materials Chemistry 20(2010), 9995-10000]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[The atomic layer deposition of CaB<sub>2</sub>O<sub>4</sub> was carried out using bis(tris(pyrazolyl)borate)calcium (CaTp<sub>2</sub>) and water as precursors.  CaTp<sub>2</sub> melts at 280 °C, undergoes solid state thermal decomposition at 385 °C, and sublimed on a preparative scale at 180 °C/0.05 Torr in about 3 hours with 99.7% recovery and 0.2% nonvolatile residue.  Self-limited ALD growth was established at 350 °C with CaTp<sub>2</sub> pulse lengths of ≥ 2.0 s.  An ALD window was observed from 300 to 375 °C, in which the growth rate was between 0.34 and 0.36 Å/cycle.  The thin film compositions were assessed by elastic recoil detection analysis (ERDA) and X-ray photoelectron spectroscopy (XPS).  The B/Ca ratios for CaB<sub>2</sub>O<sub>4</sub> films deposited at 275, 325, 350, and 400 °C were 1.84(11), 1.85(11), 1.89(13), and 1.42(10), respectively, as determined by ERDA.  Within the ALD window, hydrogen concentrations ranged from 0.22(2) to 0.35(4) atom % and the carbon and nitrogen concentrations were below the detection limits.  XPS analyses on representative CaB<sub>2</sub>O<sub>4</sub> thin films showed all expected ionizations.  X-ray diffraction experiments revealed that the as-deposited films were amorphous.  The surface morphology was assessed by atomic force microscopy and scanning electron microscopy.  The rms surface roughness of a typical 2 μm x 2 μm area for films deposited at 325 and 350 °C was 0.3 nm.  Scanning electron micrographs of these films showed no cracks or pinholes.]]></dc:description>

<dc:source><![CDATA[6th European Workshop on Beam Diagnostics and Instrumentation for Particle Accelerators, 05.-07.05.2003, Mainz, Germany]]></dc:source>
<dc:date>2003</dc:date>
<dc:description><![CDATA[The radiation source ELBE is based on a superconducting LINAC. Initially it was designed to operate in CW mode with repetition rates either 13 MHz either 260 MHz. Later it was decided to operate the accelerator with reduced repetition rates for diagnostic reasons and for certain users. Now it is possible to operate with bunch frequency 13/n MHz, where n can be 2,4,8,16,32,64 and 128. It is required that the BPM system supports any of these operation modes. A core element of the BPM electronics is a logarithmic detector AD8313 made by Analog Devices Inc. The logarithmic detector is a direct RF to DC converter rated up to 2.5 GHz. Initial design of the BPM electronic was sophisticated only for CW operation with repetition rate more than 10 MHz, since bandwidth of the AD8313 is about of 10 MHz. Additionally a sample and hold amplifier is built in to provide enough time for an ADC to make measurements. The sample and hold amplifier is synchronized with a bunch frequency. In the paper we present results of the modified BPM electronics test.]]></dc:description>

<dc:title><![CDATA[Euler-Euler Simulation of Fluid Dynamics and Mass Transfer in Bubbly Flows]]></dc:title>
<dc:source><![CDATA[12th European Fluid Mechanics Conference, 09.-13.09.2018, Wien, Österreich]]></dc:source>
<dc:date>2018</dc:date>
<dc:description><![CDATA[CFD simulations of dispersed bubbly flow on the scale of technical equipment are feasible within the Eulerian two-fluid framework of interpenetrating continua. However, accurate numerical predictions rely on suitable closure models. To achieve predictive capability, all details of the closure models have to be fixed in advance without reference to any measured data. 
Concerning the fluid dynamics of bubbly flows a baseline model has recently been proposed to this end and shown to work for a range of different applications in a unified manner1,2. This provides a reliable background which is well suited to add more complex physics. Concerning mass transfer in bubbly flows only few studies have been performed to date3. For the mass transfer coefficient, a variety of entirely different closures have been applied in rather similar situations. To facilitate predictive applications, a standard model which is validated for a broad range of conditions yet has to be developed. 
The present contribution considers two test cases from the literature, where mass transfer takes place during the absorption of oxygen into water. The first case is a bubbly mixing layer4, the second is concerned with co-current bubble column flow5. The above mentioned baseline model is used for the fluid dynamical part of the simulation model. Two different correlations for the mass transfer coefficient are considered6, which had been used in previous work. Sources of uncertainty in both, models and data, are discussed. Taking into account possible measurement errors, reasonable agreement between simulations and measurements is found for the present situations. Needs for further experimental data to facilitate qualification of a generally applicable model are specified.]]></dc:description>

<dc:description><![CDATA[The assessment of radiation damage to electronics is a complex process and requires a detailed description of the full particle energy spectra, as well as a clear characterization of the quantities used to predict radiation damage. FLUKA, a multi-purpose particle interaction and transport code, is capable of calculating proton-proton and heavy ion collisions at LHC energies and beyond. It correctly describes the entire hadronic and electromagnetic particle cascade initiated by secondary particles from TeV energies down to thermal neutrons, and provides direct scoring capabilities essential to estimate in detail the possible risk of radiation damage to electronics. This paper presents the FLUKA capabilities for applications related to radiation damage to electronics, providing benchmarking examples and showing the practical applications of FLUKA at CERN facilities such as CNGS and LHC. Related applications range from the study of device effects, the detailed characterization of the radiation field and radiation monitor calibration, to the input requirements for important mitigation studies including shielding, relocation or other options.]]></dc:description>

<dc:description><![CDATA[Since their discovery in 1991, Peptide Nucleic Acids (PNAs) have been used in molecular biology, mainly for detecting single base mismatches in oligonucleotide sequences. [1] Due to their non natural pseudo-peptide backbone, which replaces the phosphate-ribose backbone of natural DNA, PNAs are stable against enzymatic degradation. Furthermore, as they form very stable hybrids with both DNA and RNA, PNAs have also been thought to be useful for antisense and antigene therapies. Nuclear medicine is another field of research where PNAs have been used, as, for example, possible agents in the so-called pretargeting approach.[2] In this context, we are interested in the radiolabeling of PNA strands with therapeutically relevant nuclides, e.g. <SUP>188</SUP>Re. En route to explore the wide potential of this pretargeting using PNA principle, we prepared a new azido derivative of 2,2´-dipicolylamine, namely 2-azido-N,N-bis((pyridin-2-yl)methyl)ethanamine (Dpa-N<SUB>3</SUB>). It was demonstrated that Dpa-N<SUB>3</SUB> could be efficiently labeled with both [Re(CO)<SUB>3</SUB>(H<SUB>2</SUB>O)<SUB>3</SUB>]Br and [<SUP>99m</SUP>Tc(H<SUB>2</SUB>O)<SUB>3</SUB>(CO)<SUB>3</SUB>]<SUP>+</SUP> to give [Re(CO)<SUB>3</SUB>(Dpa-N<SUB>3</SUB>)]Br and [<SUP>99m</SUP>Tc(CO)<SUB>3</SUB>(Dpa-N<SUB>3</SUB>)]<SUP>+</SUP>, respectively. Furthermore, Dpa-N<SUB>3</SUB> was successfully coupled to a PNA oligomer. Subsequent labeling of Dpa-PNA with [<SUP>99m</SUP>Tc(H<SUB>2</SUB>O)<SUB>3</SUB>(CO)<SUB>3</SUB>]<SUP>+</SUP> afforded [<SUP>99m</SUP>Tc(CO)<SUB>3</SUB>Dpa-PNA] in radiochemical yields > 90% (Figure 1). Biodistribution studies of [<SUP>99m</SUP>Tc(CO)<SUB>3</SUB>Dpa-PNA] in Wistar rats showed a very fast blood clearance and modest accumulation in the kidneys. There was no significant activity in the thyroid and the stomach, demonstrating a high in vivo stability of the <SUP>99m</SUP>Tc-labeled Dpa-PNA conjugate.

<dc:description><![CDATA[This study investigates the migration behavior of U(IV) and U(VI) in the system humic acid / uranium / quartz sand by means of column experiments. Humic acid exhibits a significant influence on the transport of U(IV) and U(VI). In case of U(VI) a clear mobilizing effect was observed. There are strong indications for a similar influence of humic acid on U(IV) transport. Both redox species of uranium differ slightly in their migration behavior in presence of humic acid. This is mainly reflected in a disagreement of their total recoveries. The observed difference amounts to approximately 25 %.]]></dc:description>

<dc:source><![CDATA[7th International Conference on Multiphase Flow, ICMF, 30.05.-04.06.2010, Tampa, USA]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[To model the macroscopic bubble interactions (e.g. coalescence and breakage), the two-fluid model in conjunction with the population balance equation (PBE) approach has been considered as a practical and accurate formulation of handling bubbly flow systems. Recently, the MUltiple SIze Group (MUSIG) model appears to be one of the most direct solution methods which solves the PBE with discrete class approach and fuses seamlessly with the computational fluid dynamics (CFD) framework. Nonetheless, for complex bubbly flow structures with wide range of bubble size, large number of classes must be used to attain sufficient resolution for the bubble size distribution (BSD). This poses severe limitations on both computational time and resources. This paper focuses on introducing an alternative direct quadrature method of moments (DQMOM) (Marchisio and Fox, 2005) where the BSD is tracked through its moments by integrating out the internal coordinate. The main advantage of DQMOM is that the number of scalars to be solved is very small (i.e. usually 4-6). To assess the performance of DQMOM in measure-up with the MUSIG model, predictions of both models are validated against two experimental data by Hibiki et al. (2001) and Lucas et al. (2005). In general, the model predictions compared very well against the measured data. Associated
numerical issues and drawbacks for the DQMOM model are also discussed.]]></dc:description>

Especially, quantitative profiling of dopant concentrations is essential for process and device engineering in semiconductor industry. The most straightforward nanometrology technique is the Kelvin probe force microscopy (KPFM) where electrostatic forces are detected.
Quantitative dopant profiling by means of KPFM measurements is successfully shown on a conventional static random access memory (SRAM) cell and on
cross-sectionally prepared Si epilayer structures by applying a recently introduced new explanation of the measured KPFM signal [1]. The presented KPFM model is also used to explain observed large conductivity differences in different pulsed laser annealed Mn-implanted Ge samples by revealing a strong variation of the Fermi level position on the micrometer scale in dependence on
the annealing conditions after Mn implantation [2].
In addition, the frequency dependence of the KPFM bias is discussed. Using an active mixer, the excitation amplitude of the cantilever is almost independent of the operation frequency. As a result, the frequency dependence is samplespecific and KPFM measurements have to be performed at frequencies high enough so that the electrical properties of the locally doped semiconductor are
probed.

<dc:date>2010</dc:date>
<dc:description><![CDATA[Electrochemical Cu deposition was performed from electrolytes containing 0.1 M to 1 M CuSO4 in a well-defined magnetic gradient field. Patterned deposits resulted in all cases showing a strong correlation to this gradient field. It was observed that with increasing Cu2+ concentration the structuring effect decreases in terms of differences in topography and morphology. An explanation of this effect is presented based on local convection induced by the magnetic field gradient force which is dependent on the concentration gradient established during the deposition. Superimposed effects of Lorentz force driven convection were observed for high Cu2+ concentrations, and their influence on the deposition process is discussed.]]></dc:description>

<dc:description><![CDATA[In the present work, Euler-Euler modeling  of bubbly flows is combined with a full Reynolds stress model for the turbulence in the liquid carrier phase. Reynolds stress models have only rarely been explored in this context, although effects requiring this level of description are frequently encountered in industrial applications towards which the Euler-Euler approach is geared. In particular, source terms describing the additional bubble-induced contribution to the liquid phase turbulence with proper account for its anisotropy have not firmly been established yet. A formulation based on the direction of bubble motion relative to the liquid is given here. Two well-known variants of Reynolds stress models due to Launder, Reece and Rodi and Speziale, Sarkar and Gatski are compared. Closure relations for the bubble forces are applied that have been shown previously to work well over a range of conditions. The model is validated by comparison with a set of pipe flow data that contains variations of liquid and gas flow rates as well as different pipe diameters. An important criterion for the selection of the data was to provide measurements of individual components of the Reynolds stress tensor.]]></dc:description>

<dc:source><![CDATA[8. Workshop zum Verbundvorhaben "Wechselwirkung und Transport von Actiniden im natürlichen Tongestein unter Berücksichtigung von Huminstoffen und Tonorganika", 13.-14.04.2010, Dresden-Rossendorf, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Für die Veranstaltung wurden keine Abstracts eingereicht.

Vorgestellt wurden TRLFS-Studien mittels Eu(III) an Systemen aus Huminstoff und Al(III) verschiedenen Alters. Innerhalb des untersuchten Zeitraums von ca. 2 Tagen wurde eine Zunahme im Konkurrenzeffekt von Al(III) bezüglich der Huminstoff-Komplexbildung anderer Metalle festgestellt. Ziel der spektroskopischen Messungen war ein Nachweis struktureller Veränderungen am Huminstoff, die den beobachteten Effekt erklären. Zwar konnte gezeigt werden, dass durch die Komplexbildung von Al(III) erhebliche Veränderungen in der Mikroumgebung des Sondenmetalls Eu(III) induziert werden. Diese entsprachen jedoch nicht dem zeitlichen Trend im Konkurrenzeffekt. Aus Spektrenanalysen ging hervor, dass ein solcher Trend bei der relativ hohen Konzentration des Sondenmetalls gar nicht auftritt.
Gezeigt wurden auch erste PET-Untersuchungen zum diffusiven Transport in einem Opalinuston-Bohrkern. Mit Hilfe verbesserter Korrekturverfahren und neuer Visualisierungstechniken konnte die Methodik erheblich voran gebracht werden. Bereits nach einer Versuchsdauer von 2 Wochen konnte ein Diffusionskoeffizient abgeschätzt werden, der in Übereinstimmung mit Literaturdaten stand. Die Erfassung räumlicher Inhomogenitäten im Ausbreitungsverhalten erfordert jedoch längere Messzeiten und einen modifizierten Versuchsaufbau, welcher ebenfalls vorgestellt wurde.]]></dc:description>

<dc:source><![CDATA[International Journal of Radiation Oncology Biology Physics 2002(2002)53, 36-42]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[Purpose: Compared to photon irradiation, carbon ions provide physical and biologic advantages that may be exploited in chordomas and chondrosarcomas. 
Methods and Materials: Between August 1998 and December 2000, 37 patients with chordomas  (n = 24) and chondrosarcomas (n = 13) were treated with carbon ion radiotherapy within a Phase I/II trial. Tumor conformal application of carbon ion beams was realized by intensity-controlled raster scanning with pulse-to-pulse energy variation. Three-dimensional treatment planning included biologic plan optimization. The median tumor dose was 60 GyE (GyE =Gy x relative biologic effectiveness). 
Results: The mean follow-up was 13 months. The local control rate after 1 and 2 years was 96% and 90%, respectively. We observed 2 recurrences outside the gross tumor volume in patients with chordomas. Progression-free survival was 100% for chondrosarcomas and 83% for chordomas at 2 years. Partial remission after carbon ion radiotherapy was observed in 6 patients. Treatment toxicity was mild. 
Conclusion: These are the first data demonstrating the clinical feasibility, safety, and effectiveness of scanning beam delivery of ion beams in patients with skull base tumors. The preliminary results in patients with skull base chordomas and low-grade chondrosarcomas are encouraging, although the follow-up was too short to draw definite conclusions concerning outcome. In the absence of major toxicity, dose escalation might be considered.]]></dc:description>

<dc:description><![CDATA[One of the main goals of materials research using ion beams is to synthesize nanostructures, for example semiconducting or metallic nanocrystals (NCs) in insulating films. A great effort is currently devoted to NC fabrication for micro- and optoelectronics by ion beam synthesis (IBS), because this method is compatible with modern CMOS technology. The present contribution addresses the Si NC formation by conventional ion implantation into the gate oxide and by a non-conventional IBS approach of ion beam mixing of SiO2/Si interfaces in thin gate oxides, with special emphasis on well-controlled size and position tailoring. The two approaches will be compared and related technological challenges discussed. Compared to conventional Si NC synthesis by Si+ ion implantation into the gate oxide, we take advantage of the self-alignment ion beam mixing process, i.e., the Si NCs are formed in SiO2 at a well-controlled small distance of ca. 2 nm from the Si/SiO2 interfaces. The technical applications in non-volatile nanocrystal memories and in light emitting field-effect transistors (LEFET) are demonstrated. 
The Si NC MOSFETs were fabricated as nMOSFET devices in a standard 0.6 µm CMOS process line. Their electrical characteristics have been evaluated in terms of write/erase voltage, duration of the programming time, endurance and retention for different ion irradiation and annealing conditions. For the investigation of the light-emitting characteristics of the same nMOSFETs, an AC voltage was applied to the gate in order to inject charges of both polarities into the NCs. AC voltage and frequency dependent electroluminescence spectra in the wavelength region of 400-1000 nm were recorded for different annealing conditions. The performance of the Si NC memories and LEFETs with further possibilities of optimization of efficient charge storage and light emission properties will be discussed.]]></dc:description>

<dc:source><![CDATA[Advanced Accelerator Concepts Workshop, 13.-19,06,2010, Annaplolis, USA<br>1299: AIP Conference Proceedings, 715]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[For the past ten years, the highest proton energies accelerated with high-intensity lasers was 58 MeV, observed in 2000 at the LLNL NOVA Petawatt laser, using flat foil targets. Recently, 67.5 MeV protons were observed in experiments at the Los Alamos National Laboratory (LANL) Trident laser, using one-fifth of the PW laser pulse energy, incident into novel conical targets. We present a focused study of new theoretical understanding of this measured enhancement from collisional Particle-in-Cell simulations, which shows that the hot electron temperature, number and maximum energy, responsible for the Target Normal Sheath Acceleration (TNSA) at the cone-top, are significantly increased when the laser grazes the cone wall. This is mainly due to the extraction of electrons from the cone wall by the laser electric field, and their boost in the forward direction by the v×B term of the Lorentz force. This result is in contrast to previous predictions of optical collection and wall-guiding of electrons in angled cones. This new wall-grazing mechanism offers the prospect to linearly increase the hot electron temperature, and thereby the TNSA proton energy, by extending the length over which the laser interacts in a grazing fashion in suitably optimized targets. This may allow achieving much higher proton energies for interesting future applications, with smaller, lower energy laser systems that allow for a high repetition rate.]]></dc:description>

<dc:title><![CDATA[Experimental investigation of the flow in a bubble column]]></dc:title>
<dc:source><![CDATA[Seminar, 24.11.2005, Karlsruhe, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Computational Fluid Dynamics (CFD) models for two-phase flows always require closure relations representing the nature of the forces acting at the interface between the participating phases. This is   vital for the modelling of momentum transfer term. In case of a gas-liquid flow, it is expressed in terms of forces acting on bubbles.  The present study uses instantaneous high-speed video observations of the bubble motion to validate models for the interfacial forces.
	The turbulent diffusion coefficient of the gaseous phase is obtained by a statistical evaluation of the movement of bubbles in a swarm, which is affected by the turbulence of the liquid phase. After the bubble trajectories were identified, the lateral displacement of bubbles was statistically analysed by constructing probability density functions. The dispersion coefficients of the standard distributions were found to grow proportionally to the square-root of the time. This supports the assumption of a diffusion model for the lateral displacement. Deviations from the linear dependency were identified to be the result of deterministic oscillatory motions of the rising bubbles. 
	Another objective is objective is to demonstrate the capabilities of the high-speed stereo-imaging technique to study the single (isolated) bubble dynamics in a vertical bubble column. The reconstruction algorithm of the 3D bubble trajectories from the stereo images of the bubble projection is presented. The bubble size, shape, orientation as well as bubble aspect ratio are investigated.
	The first results of experiments on bubble motion in a vary narrow flat bubble column (width-100 mm, depth-8 mm, height  600 mm) obtained for the validation of numerical predictions achieved using DNS-based analyses (Wörner et al. FZK) are presented. Results of high-speed video measurements of bubble parameters (bubble shape, size, rising velocity etc.) as well as PIV measurements of velocity of the liquid phase are discussed.]]></dc:description>

<dc:title><![CDATA[Quantification of secondary Fe-phases formed during sorption experiments on chlorites]]></dc:title>
<dc:source><![CDATA[Int. Conference on the Applications of the Mössbauer Effect, 21.-25.09.2003, Muscat, Oman]]></dc:source>
<dc:date>2003</dc:date>
<dc:description><![CDATA[During batch sorption experiments of heavy metals on chlorite not only sorption reactions take place, but also reactions of chemical weathering leading to mineral dissolution and the formation of secondary phases, in particular the Fe-oxy-hydroxide ferrihydrite. Despite of its minor mass, ferrihydrite plays a major role in removing aqueous uranium(VI) from solution, because of its large specific surface area which it introduces into the system. To accurately model the sorption and transport on or through geological materials it is necessary to precisely determine the mass of the newly-formed Fe-phase. As the relative mass of the ferrihydrite within the geological matrix  was too small, it proved impossible to use powder X-ray diffraction or some other spectroscopic technique, e.g. Raman spectroscopy, for its identification and quantification. 
Because of the ability to discriminate different sites and oxidation states of iron, Mössbauer spectroscopy was the method of  choice. At first spectra of pure chlorite and pure ferrihydrite were measured. In a second step, simulated spectra were compared with spectra from powders with known chlorite/ ferrihydrite ratios. There  was a good agreement between the predicted values and those obtained by the spectrum fit. Finally, the calibration spectra were used to investigate real geological material and to estimate the fraction of  the secondary Fe-phase, which has formed during the sorption experiments. Changes of  less than 2 % (absolute) could be detected. It should be noted that there is a strong overlap between the different subspectra and that a good counting statistics is required.

<dc:source><![CDATA[Vacuum 78(2005)2-4, 285-290]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Hydrogen plays an important role in GaN and related alloys. It is often a part of  the growth environment and can be incorporated in GaN during different processing steps. Its behaviour  is rather complicated and poorly understood. GaN doped with Fe has currently gained an increasing interest as a suitable magnetic semiconductor for spintronic applications. Here, we report results of the study on GaN doped with Fe and codoped with Mg for deep acceptors, Si for shallow donors and isoelectronic Al. Samples were grown by the chemical transport process in the form of small (~ 0.3 mm) crystallites and subsequently pressed to form platelets. As-grown samples and after annealing in different atmospheres (successively with N<sub>2</sub> and NH<sub>3</sub>) were studied. Hydrogen concentration were determined by NRA using the <sup>15</sup>N profiling method. Hydrogen release due to the analysing beam was evaluated using the molecular recombination model. Effective H-release cross-section was found to be the same for all GaFeN samples, independently of codoping. The lowest concentration of hydrogen among as-grown materials was revealed in GaFeN samples. Codoped materials showed higher hydrogen concentration, increasing in the following sequence: Mg, Si and Al. Hydrogen concentration can be substantially reduced by annealing in N<sub>2</sub> atmosphere, whereas subsequent annealing in NH<sub>3</sub> produces hydrogenation, however, to concentrations below that for pristine samples. The model of these processes has been proposed.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Diamond-like carbon (DLC) is a promising protective coating for future optical storage technologies. The requirements place conflicting constraints on the nature of the DLC. It must be transparent at 400 nm, hard and wear-resistant, uniform, pinhole-free, have a low stress and be deposited at high rate without a high heat load on a plastic substrate. In order to optimise the films under these constraints, we have studied in detail the band gap, stress, density and Young's modulus of hydrogenated amorphous carbon (a-C:H) films deposited by plasma enhanced chemical vapour deposition using a large area electron cyclotron wave resonance source of 14 in. diameter and a variety of hydrocarbon gas sources. We have been able to produce wear-resistant carbon coatings with a high transparency at 400 nm without damaging the plastic disks. We also show that for these films the refractive index can be used as a rapid empirical means of property correlation.

<dc:title><![CDATA[Porous silicon as an intermediate layer for heterojunction solar cells on p-type Si crystalline substrates]]></dc:title>
<dc:source><![CDATA[19th European Photovoltaic Solar Energy Conference, 07.-11.06.2004, Paris, France, 588]]></dc:source>

<dc:description><![CDATA[The study of the influence of ITO deposition process on the defect formation in the interface region of heterojunctions (HJ) is done. The role of intrinsic a-Si:H and as an alternative a thin porous Si buffer layer is analyzed. It is shown that a thin porous Si as a buffer layer in HJ solar cells leads to the improvement of the HJ solar cells efficiency since this layer serves as a protection one of the Si substrate during the ITO deposition process. By DLTS method it is observed that damages created during the deposition of ITO layer can be essentially suppressed by a thin a-Si:H or thin porous Si buffer layers. In case of porous silicon formation by the electrochemical etching the process is softer and this thin intermediate layer has similar properties as a-Si:H concerning the hydrogen concentration and the characteristics of Si-H bonds. This conclusion was derived from the Nuclear Reaction Analysis (NRA) and Raman measurements, which are performed on porous-Si/crystalline Si structures. It is concluded that the main role of a thin porous Si layer in a Si based heterojunction structure is the improvement of the interface properties of HJ solar cells due to a protection of the Si substrate during the depositions of a-Si:H and ITO layers.]]></dc:description>

<dc:source><![CDATA[Materials Science Forum 457-460(2004), 351-354]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[The formation of 3C-SiC epitaxially grown on Si wafers is still a considerable problem. Due to the 20% misfit between Si and 3C-SiC the defect density in the film is very high. the partial melting and subsequent recrystallization of the film by the flash lamp process can improve the quality of the thin 3C-SiC films. In this paper the microstructure of the annealed and partially recrystallized 35 nm thick films is studied by transmission electron microscopy. The films were grown by APCVD using Silane and Propane. The flash lamp annealing system consists of Xe lamps powered by discharging capacitors producing pulses of 20 ms. After irradiation almost free of defects 3C-SiC trapezoidal protrusions (TPs) are formed at the lower part of the film. In the uppermost part of the film the defect density was also reduced. The good quality of the TPs is shown by high resolution cross-section TEM observations. The good quality of the films was also confirmed by Plane View TEM observations of the moiré patterns in the as grown and annealed films. Moiré patterns are formed when the electron beam penetrates both the Si and the SiC lattices and are very sensitive to any lattice distortion or defects.]]></dc:description>

<dc:source><![CDATA[Materials Science Forum 457-460(2004), 1515-1518]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[The formation of SiC on Insulator (SiCOI) using a tool wet sacrificial oxidation is studied. The wet oxidation in 3C-SiC is very anisotropic strongly depended on the defect density, especially the inversion domain boundaries (IDBs). The SiCOI structure was realized by depositing of 35 nm thick 3C-SiC film on (100)-Si substrate by APCVD subsequently the film was annealed by flash lamps. The flash lamp annealing system consists of Xe lamps powered by discharging capacitors producing pulses of 20 ms. After radiation two zones can be distinguished, upper and lower, exhibiting high and low defect density, respectively. The highly defected upper zone was etched by wet sacrificial oxidation at 1150°C for 16 min. forming a 50nm thick oxide layer on the top of a good quality, 20nm thick, 3C-SiC film. In parallel, a buried oxide layer having a mean thickness of 44nm was formed by oxidation of the Si substrate through existing channels created in the SiC by the preferential wet oxidation of the IDBs which touch the SiC/Si interface. Through the oxided channels the Si substrate is oxided fast forming a continuous buried oxide layer realizing the SiCOI structure. ]]></dc:description>

<dc:description><![CDATA[To evaluate the influence of humic substances upon the extent of neptunium(V) sorption by granite, the sorption of neptunium(V) on granite in the absence and presence of humic acid was studied under anaerobic conditions as a function of pH in a series of batch equilibrium experiments. The neptunium and humic acid sorption onto the mineral constituents of granite (quartz, orthoclase, albite, biotite, and muscovite) was also studied to identify the mineral component which dominates the sorption of neptunium and humic acid on granite. The study showed that the neptunium sorption is affected by both the pH and the presence of humic acid. An increased mobility of neptunium was found between pH 7 and pH 11 in the presence of humic acid. As dominating mineral phase in the granite for the neptunium sorption, biotite was identified.]]></dc:description>

<dc:description><![CDATA[Uranium is a long-living radionuclide that represents ecological and human health hazards. The mining and processing of uranium during the last decades for nuclear fuel and nuclear weapon production resulted in generation of significant amounts of radioactive waste. It is critical that the uranium in these wastes has to be effectively immobilized and removed away in order to prevent ground water contamination. Microbial biosorption of U(VI) was proposed as one of the methods for uranium immobilization. In this paper, we describe the isolation of bacterial strains from water and soil samples collected from different uranium contaminated environments. Phylogenetic analysis of these strains revealed that they are related to Stenotrophomonas maltophilia, Bacillus sphaericus, Microbacterium oxydans, Pseudomonas rhodesiae  etc. As estimated by using ICP-MS these natural isolates possess a high ability to accumulate uranium and other heavy metals such as Cd, Pb, Ni and Ag. The bacterial uranium tolerance was studied using flow cytometry techniques. X-ray absorption near-edge structure analysis showed that the cells of these strains precipitate U(VI) as autunite-like phase (inorganic uranyl phosphate phase) at pH 4.5, probably due to the release of the inorganic phosphate from the cells. However, at pH 2 the uranium bonding was consistent with the formation of complexes with organic bound phosphate of the cell surface. These results are in agreement with those found by infrared measurements.Transmission electron microscope and energy dispersive X-ray analysis showed strain-specific extracellular and/or intracellular uranium accumulation to varying degrees.]]></dc:description>

<dc:description><![CDATA[Abstract: We present a dielectric continuum model approach for studying the electrical polarization properties of interface polarization coupled BaTiO3, BaTiO3-ZnO, and ZnO-BaTiO3-ZnO thin-film structures consisting of several hundred nanometer thick layers. Our model augments the effects of electric field driven switchable polarization and depletion layer formation with spontaneous interface polarization coupling. Wurtzite-structure (piezoelectric) n-type ZnO and perovskite-structure (ferroelectric) highly insulating BaTiO3 layers were prepared and investigated. The coupling between the nonswitchable spontaneous polarization of ZnO and the electrically switchable spontaneous polarization of BaTiO3 causes strong asymmetric polarization hysteresis behavior. The n-type ZnO reveals hysteresis-dependent capacitance variations upon formation of depletion layers at the ZnO/BTO interfaces. We obtain a very good agreement between our model generated data and our experiment. Our model approach allows for derivation of the amount and orientation of the spontaneous polarization of the piezoelectric constituents and can be generalized toward multiple-layer piezoelectric-semiconductor ferroelectric heterostructures. We identify interface polarization coupled triple-layer ZnO-BTO-ZnO heterostructures as two-terminal unipolar ferroelectric Bi-junction transistor for use in memory storage.]]></dc:description>

<dc:description><![CDATA[The presentation starts from sustainability considerations of different energy carries like oil,  hoard cool, or nuclear energy.
It is highlighted, that in terms of sustainability nuclear energy suffers from the danger of proliferation of weapons grade material, the maximum damage of a conceivable severe accident, and the extremely long isolation period of the nuclear waste in the final disposal. Discussing the safety analysis of so called boron dilution transients in PWRs, the behaviour of the reactor pressure vessel during a severe core melt accident, and the possibilities of the transmutation of long lived radio-nuclides it is shown how modern nuclear safety research can contribute to improved sustainability performance of nuclear energy.

<dc:description><![CDATA[A general framework is presented for the modeling of turbulent dispersion in Eulerian Multi-Phase Flows. The approach is based on a double averaging procedure of the local instant equations. We start with the ensemble averaged equations of Eulerian multi-phase flow. We perform a second time average of these, in order to form equations which may be used to model turbulent multi-phase flows. These are conveniently expressed in terms of Favre or Mass averaged variables. Turbulent dispersion is modeled by performing a time average of the interphase drag term in its modeled form, and expressing it in terms of Favre averaged variables. The resulting double averaged momentum equations contain additional terms which account for a turbulent dispersion force. We call the resulting model the Favre Averaged Drag (FAD) model for turbulent dispersion. It is first presented in a general form which may be used in conjunction with any Reynolds averaged turbulence model, and for an arbitrary number of phases with arbitrary morphologies. For the purposes of this study, we make two further specializations, to poly-dispersed multiphase flows, and to turbulence models which employ the eddy diffusivity hypothesis. The resulting model is compared to several other models that have appeared in the literature, We show that all are special cases of the FAD model, within certain physical and mathematical limitations. Hence the FAD model encompasses all of these models, but has a potentially wider range of universality. The FAD model has been implemented in the commercial CFD package, CFX-5, and tested against a range of dispersed multiphase flows, including bubbly flows in vertical pipes, and liquid-solid flows in mixing vessels. The FAD model is shown to yield superior predictions in all cases.]]></dc:description>

<dc:description><![CDATA[The investigation of reactor pressure vessel (RPV) materials from decommissioned NPPs offers the unique opportunity to scrutinize the irradiation behaviour under real conditions. Material samples taken from the RPV wall enable a comprehensive material characterisation. The paper describes the investigation of trepans taken from the decommissioned WWER-440 first generation RPVs of the Greifswald NPP. Those RPVs represent different material conditions such as irradiated (I), irradiated and recovery annealed (IA) and irradiated, recovery annealed and re-irradiated (IAI). The working program is focussed on the characterisation of the RPV steels (base and weld metal) through the RPV wall. The key part of the testing is aimed at the determination of the reference temperature T0 following the ASTM Test Standard E1921-05 to determine the fracture toughness of the RPV steel in different thickness locations.
In a first step the trepans taken from the RPV Greifswald Unit 1 containing the X-butt multilayer submerged welding seam and from base metal ring 0.3.1 both located in the beltline region were investigated. Unit 1 represents the IAI condition. It is shown that the Master Curve approach as adopted in ASTM E1921 is applicable to the investigated original WWER-440 weld metal. The evaluated T0 varies through the thickness of the welding seam. The lowest T0 value was measured in the root region of the welding seam representing a uniform fine grain ferritic structure. Beyond the welding root T0 shows a wavelike behaviour. The highest T0 of the weld seam was not measured at the inner wall surface. This is important for the assessment of ductile-to-brittle temperatures measured on sub size Charpy specimens made of weld metal compact samples removed from the inner RPV wall. Our findings imply that these samples do not represent the most conservative condition. Nevertheless, the Charpy transition temperature TT41J estimated with results of sub size specimens after the recovery annealing was confirmed by the testing of standard Charpy V-notch specimens. The evaluated Charpy-V TT41J shows a better accordance with the irradiation fluence along  the wall thickness than the Master Curve reference temperature T0. 
The evaluated T0 from the trepan of base metal ring 0.3.1 varies through the thickness of the RPV wall. T0 increases from -120°C at the inner surface to -104°C at a distance of 33 mm from it and again to -115°C at the outer RPV wall. The KJc values generally follow the course of the MC, although the scatter is large. The re-embrittlement during 2 campaigns operation can be assumed to be low for the weld and base metal.]]></dc:description>

<dc:description><![CDATA[Structures of the natural bacterial and archaeal communities in soil and water samples from three U wastes in Germany and  from two in the USA were compared by using the 16S rDNA and the RISA retrievals. We found that the composition of the bacterial communities is very diverse and site-specific. However, several particular groups of bacteria including also novel lineages were identified in the samples of all habitats. Some of the retrieved 16S rDNAs were related to sequences already found in other heavy metal contaminated environments and it seems that they represent not yet cultured bacterial populations characteristic for the latter. 
A quantitative analysis of the Geobacter sp. populations demonstrated that they are  present  in low but site-specific number at the studied environments.
The archaeal populations in the studied environments were, in contrast to the bacterial, not very dense and they were limited to only two lineages of not yet cultured groups of  Crenarchaeotae.  Only in one of the samples studied representatives of methanogenic Euryarchaeotae  were identified.
Chemolithoautotrophic strains involved in U mobilization and also heterotrophic U reducing and immobilizing strains were cultured from  the samples from the U wastes. In addition, several ultramicrobacterial isolates were cultured on oligotrophic media. These isolates were characterized morphologically and physiologically. Their interactions with U and several other metals were studied by using ICP-MS, EXAFS, and IR spectroscopy.

<dc:description><![CDATA[The Multidot Nano-flash Memory suggested by Tiwari [APL69(1996)1232] is a promissing candidate for succeeding the common Floating Gate Flash Memory. 
Its most challenging configurational feature is a layer of insulated Si nanoclusters (NCs) within the oxide of a MOS-like structure.
Here, we present experimental evidence that the theoretical concept predicting the self-organization of delta-layers of Si NCs at ion irradiated interfaces is valid (cf. Heinig [APA77(2003)17]).
In this approach of "bottom-up" structuring, unconventionally, a 15nm thin buried SiO<SUB>2</SUB> layer, which is enclosed by a 50nm poly-Si capping layer and the Si substrate, is irradiated with Si ions. Ion impact drives the system to a state far from thermodynamic equilibrium, i.e. the local composition of the target is modified to a degree unattainable in common processes. A region of SiO<SUB>x</SUB> (x<2) -- where x is a function of depth -- is formed which is not stable.
During annealing, the system relaxes towards equilibrium, i.e. phase separation (via spinodal decomposition and nucleation) sets in. Within a certain time window of annealing, the structure of the system matches with a structure similar to the Multidot Memory device, the principal character of which is a 2D layer of Si nanoclusters of (d~3nm) which is embedded in a 3D SiO<SUB>2</SUB> matrix at a distance of ~3nm from the Si substrate.
The experimental handicap that tiny Si NCs (d<3nm) which are embedded in SiO<SUB>2</SUB> are not visible in common XTEM is resolved by a novel method which applies Ge as contrast enhancing element in TEM studies of tiny Si NCs.]]></dc:description>

<dc:description><![CDATA[Located in presynaptic cholinergic nerve terminals, the vesicular acetylcholine transporter (VAChT) represents a potential target for quantitative visualization of early degeneration of cholinergic neurons in Alzheimer´s disease using PET. Benzovesamicol derivatives are proposed as radioligands for this purpose. We report QSAR studies of vesamicol and benzovesamicol derivatives taking into account the stereoselectivity of the VAChT binding site. Use of different data sets and different models in this study revealed that both enantiomers of 5-fluoro-3-(4-phenyl-piperidin-1-yl)-1,2,3,4-tetrahydro-naphthalen-2-ol (5-FBVM) are promising candidates, with predicted VAChT affinities between 6.1 and 0.05 nM. The synthesis of enantiopure (R,R)- and (S,S)-5-FBVM and their corresponding triazene precursors for future radiofluorination is reported. Both enantiomers exhibited high in vitro affinity for VAChT [(+)-5-FBVM: Ki = 6.95 nM and (-)-5-FBVM: Ki = 3.68 nM] and were selective for s2 receptors (~70-fold), only (+)-5-FBVM is selective for s1 receptors (~5-fold). These initial results suggest that (+)-(S,S)-5-FBVM warrants further investigation as a potential radioligand for in vivo PET imaging of cholinergic nerve terminals.]]></dc:description>

<dc:description><![CDATA[The CFD package CFX-5 has been used to predict the development of upward directed gas-liquid flows in a vertical pipe. Under the assumption of monodisperse bubbles the dilute gas-liquid flow has been predicted using the Eulerian framework of multiphase flow modeling. The capabilities of the CFX-5 flow solver have been extended by taking into account additional non-drag forces like lift, turbulent dispersion and wall lubrication forces. Range of applicability and accuracy of the numerical model have been validated against measured gas void fraction profiles obtained at the MT-Loop test facility of the Forschungszentrum Rossendorf (FZR) in the bubbly flow regime. Best agreement of numerical results with experimental data could be obtained for a wide range of experimental conditions, if Menter s k-w Shear Stress Transport (SST) turbulence model has been used in combination with the Favre averaged drag (FAD) turbulent dispersion force model as derived by Burns [1]. Furthermore results of extensive numerical experiments [2] for the examination and comparison of different model formulations for the wall lubrication and turbulent dispersion forces are presented in this paper.]]></dc:description>

<dc:description><![CDATA[Focused ion beams from liquid metal ion sources (LMISs) have become of increasing interest in recent years. A promising source is one of Ge ions, important in the semiconductor technology; e.g., local doping of SixGe1-x structures. The beam energy spread, ΔE½, of the source - which, through the chromatic aberrations of the system determines the final spot size at the target - and the peak energy deficit (PED), as well as the mass spectra of a Au73Ge27 eutectic liquid metal alloy ion source were investigated. Source temperature was the main experimental parameter. The melting point of the eutectic was determined as 366oC. ΔE½, measured with a retarding field analyser, is expressed as the full width of the distribution at half its maximum height (FWHM). Doubly-charged ions attain twice the energy of singly-charged ions, for a given voltage drop, and this has to be taken into account when determining the value of ΔE½ and the PED. Ge was found to be much more abundant in the doubly-charged state, in accordance with Brandon`s criterion [1]. From PED measurements we conclude that Ge++ as well as Au+ and Ge+ are directly field-evaporated, whereas Au++ is post-ionized from the singly-charged state. As expected for liquid metals that display a linear decrease of their surface tension coefficient with temperature, the liquid metal ion source under investigation shows an increase in emission current with increasing temperature. This is in contrast to Si containing metallic glass alloys, e.g., AuSi or AuGeSi, that have an anomalous surface tension coefficient [2]. The mass spectra, where obtained with an ExB filter. Alongside the main monomer species, cluster ions, the result of droplet disintegration, were identified. The conclusions drawn from a study of the ratio of the abundance of doubly to singly-charged monomer ions, support our deductions from PED measurements, as far as the mechanisms of creation of the monomer ions are concerned.

<dc:description><![CDATA[The volatility of plutonium oxides in the O2-H2O(g)/SiO2(s) system has been studied by thermo-chromatography in the temperature range 1475 to 600 K. Oxides of thorium, protactinium, uranium, neptunium, and americium in trace amounts have been studied for comparison. Oxide samples containing 105  1016 actinide atoms were heated in the starting position of the ther-mochromatographic silica columns.  Mixtures of helium, oxygen and water vapor were applied as reactive mobile gas phase. Resulting from thermochromatography the volatile actinide spe-cies are deposited in the column downstream, thus creating inner chromatograms along a temperature gradient. At the end of each experiment the actinide chromatograms were meas-ured by alpha spectrometry. Gamma spectrometry was used to measure protactinium.
Plutonium was found to be volatile in humid oxygen at temperatures above 1300 K. The Pu volatility is lower than that of uranium, but higher as one would expect for stable Pu(IV) which is nonvolatile under the applied experimental conditions. The Pu volatility is assigned to PuO2(OH)2(g). The experimental results give evidence of the oxidation of PuO2 and NpO2 to higher oxides by moist oxygen.

<dc:source><![CDATA[Surface &amp; Coatings Technology 204(2010)16-17, 2551-2558]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Crystallographic structure and lattice rotation of the expanded austenite produced by means of low temperature plasma nitriding is investigated. The microstructure of the nitrogen enriched layer has been investigated by means of X-ray diffraction (XRD) while the lattice rotations in the nitrided zone were assessed by electron backscattered diffraction (EBSD). The nitrogen depth profiles have been determined by means of glow discharge optical emission spectroscopy and nuclear reaction analysis. XRD shows the presence of the expanded austenite or γN phase in all the nitrided samples characterized by average larger lattice spacing in relation to non-nitrided steel matrix. EBSD investigation demonstrates that in addition to the lattice expansion nitrogen incorporation into the stainless steel matrix induces significant lattice rotations. The amount and direction of these crystallographic plane rotations are function of the initial orientation. An unusual evolution of the 220 γN line as a function of the nitriding duration is observed together with an anomalously high intensity ratio of the 111 and 200 γN  and matrix lines. The XRD results are interpreted on the basis of the lattice rotations of diffracting planes, nitrogen concentration gradient, nitrogen diffusion anisotropy and residual stress. It shows that these rotations are a pertaining feature for the understanding of the γN microstructure.]]></dc:description>

<dc:description><![CDATA[Photoactivation measurements on Sm-144 have been performed with bremsstrahlung endpoint energies from 10.0 to 15.5 MeV at the bremsstrahlung facility of the superconducting electron accelerator ELBE of Forschungszentrum Dresden-Rossendorf. The measured activation yield for the Sm-144(gamma,n) reaction is compared with the calculated yield using cross sections from previous photoneutron experiments. The activation yields measured for all disintegration channels Sm-144(gamma,n), (gamma,p), and (gamma,alpha) are compared to the yield calculated by using Hauser-Feshbach statistical models. A new parametrization of the photon strength function is presented and the yield simulated by using the modified photon strength parameters is compared to the experimental data.]]></dc:description>

<dc:source><![CDATA[Journal of Physics D: Applied Physics 41(2008), 085208]]></dc:source>
<dc:date>2008</dc:date>
<dc:description><![CDATA[Samples of pure titanium were laser nitrided by continuous wave CO2 laser irradiation in mixtures of nitrogen and argon gas with different ratios. In all cases, TiN formed in the surface. The properties and the characteristics of the processed samples were evaluated using nanoindentation technique, optical microscopy, surface roughness measurements, X-ray diffraction and wear resistance measurements. It was found that the nitrogen content in the gas atmosphere has a massive effect on the microstructure and the mechanical properties of the laser nitrided samples. For all treated samples, the mechanical properties are improving with the nitrogen content in the gas atmosphere. Moreover, the thickest TiN layers with high values of the microhardness and good wear resistance were obtained for the titanium sample that was treated in 80% N2 and 20% Ar. In addition, the strain and the grain size of the coatings formed at the surface of the laser nitrided titanium samples were determined from X-ray data.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Bacterial diversity was studied in a water sample collected from a depth of 290-324 m below the land surface from the monitoring site S15 near the city of Tomsk, Siberia, Russia. In order to overcome the problems of culturability of bacteria, we applied a direct molecular approach based on PCR amplification and cloning of the 16S rDNA of the members of the natural bacterial communities. 65% of the cloned sequences were almost identical to the 16S rRNA genes of Dechlorosoma sp. belonging to the Rhodocyclus group of b-subclass of Proteobacteria. Relatively high was the number of the sequences which shared high identities with the 16S rRNA genes of some cultured g-Proteobacteria (6.9%), a-Proteobacteria (4.6%) and with the sequences of mostly uncultured members of Cytophaga/Flavobacterium/Bacteroides (5.4%), Actinobacteria (4.6%) and Planctomycetales (2.3 %). The rest of the retrieved sequences were clustered in small groups, each containing about 1 % of the total number of clones, and they matched with 16S rDNA sequences of Bacillales, Holophaga/Acidobacteria, Nitrospira, and d-Proteobacteria, respectively.]]></dc:description>

The focus is on the production of strangeness using proton and ion beams, as well as the photo- and electroproduction of strangeness, as observed at modern facilities.  The elementary production of K+- and phi mesons as well as Lambda, Sigma hyperons on the nucleon is described. Based on these results, the production of strange mesons and strange baryons on nuclear targets, as well as the creation of light hypernuclei is discussed, emphasizing the influence of the nuclear medium.]]></dc:description>

<dc:description><![CDATA[In the framework of the EU project VALCO, measurements at the V-1000 test facility of the Russian Research Centre 'Kurtschatov Institute' are used for the validation of three-dimensional neutronic calculations. Experimental results of steady states and kinetic experiments are available for comparisons with calculations. Respective DYN3D calculations have been performed by using the cross section libraries generated with the codes HELIOS, CASMO and WIMS.
Results obtained by the DYN3D code are compared with steady-state measurements for two different configurations of the V-1000 facility. Pin-power distributions measured within one fuel assembly are compared to the results of the pin power reconstruction implemented in DYN3D. 
Two kinetic experiments performed in the V-1000 facility were simulated by the DYN3D code. Comparisons of the calculated results with the measurements at the in-core detector positions are given. The calculated fast flux of the nodes, situated near to the ionisation chambers of the two reactimeters, is compared with the detector signal. The results of the relative detector rates coincide with the measurements. The dynamical reactivities are obtained from the core-averaged flux by inverse point kinetics.  It is compared with reactivity curves, provided by the two reactimeters.]]></dc:description>

<dc:title><![CDATA[Influence of irradiation on para- and autocrine regulation of extracellular S100A4 (metastasin) and its receptor RAGE in B16 mouse melanoma cells]]></dc:title>
<dc:source><![CDATA[21st meeting of the European Association for Cancer Research (EACR-21), 26.-29.06.2010, Oslo, Norway]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background: 
Malignant melanoma is one of the most invasive and metastatic tumors. A common therapeutic approach towards metastases will combine radiation with chemotherapy and/or surgery. The interaction between tumor and inflammatory cells, e.g., via S100A4 (metastasin) and the receptor for advanced glycation endproducts (RAGE), is hypothesized to play a key role in metastasis of melanoma. In this study the contribution of para- and autocrine S100A4-RAGE activation to growth, motility and migration of metastatic melanoma and inflammatory cells before and post irradiation was investigated.

Materials and methods: 
Mouse melanoma cells (B16), macrophages (RAW; a model for tumor associated macrophages (TAM)) and B16/RAW cocultures (ratio 1 to 5) were exposed to single dose irradiation (5, 10, and 20 Gy, compared to sham-irradiated controls) for 0, 3 and 6 days. S100A4 and RAGE expression in these cells was quantified via real-time RT-PCR, Western-blot analysis and immunochemistry. Cell growth and cellular viability was detected by MTT assay. Migration assays of non- and irradiated cells were performed with and without chemoattractants (supernatants of irradiated cocultures after 6 days). Additionally, the actin cross-linker L-plastin was investigated as a migratory marker. 

Results: 
Post irradiation, S100A4 and RAGE mRNA expression was significantly increased in B16 and RAW cells but not in cocultivated cells. S100A4 protein expression was only detected in irradiated B16 cells whereas RAW cells always showed high levels in non- and irradiated cells. Interestingly, cocultures showed only minor S100A4 expression levels with a further reduction of S100A4 after irradiation. In contrast, RAGE protein showed only slight differences. A significant reduction of cell viability was observed after irradiation via MTT assay. On the other hand, migratory activity was significantly increased in B16 and cocultures after irradiation whereas RAW cells showed a significant decrease. Furthermore, chemoattractants significantly induced the migration in non-irradiated B16 cells. 

Conclusion: 
Irradiation of both melanoma cells and macrophages alters their migratory and invasive activity. Under conditions of cocultivation these effects were more pronounced. We suppose an involvement of para- and autocrine regulation of extracellular S100A4 and its receptor RAGE in melanoma cells and TAM, thereby changing functional properties of melanoma cells towards a promigratory phenotype.]]></dc:description>

<dc:description><![CDATA[Bacteria, ubiquitous in all aquatic and soil systems, can interact in many ways with actinides. They can mobilize or immobilize actinides in the environment, leading to their dissolution or precipitation. Knowledge of bacteria-actinide interactions is important for understanding the migration behaviour of the latter in the biogeosphere. In this work, a combination of Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy, Infrared (IR) spectroscopy, Transmission Electron Microscopy (TEM) and Energy Dispersive X-ray Spectroscopy (EDS) was used to conduct a molecular and atomic analysis of the uranium complexes formed by different bacterial strains isolated from uranium mining waste piles. EXAFS analysis showed that the cells of Stenotrophomonas maltophilia JG-2, Pseudomonas rhodesiae R5 and Myxococcus xanthus precipitate U(VI) as autunite-like phase at pH 4.5, probably due to the release of the inorganic phosphate from the cells. However, in the case of B. sphaericus JG-A12 the uranium bonding was consistent with the formation of a ternary complex with phosphate and carboxylate. These results are in agreement with those found by Infrared measurements. TEM and EDS analysis showed strain-specific extracellularl and/or intracellularl uranium accumulation to varying degrees. In  B. sphaericus JG-A12 the uranium is located at the cell wall, while the cells of S. maltophilia JG-2 and P. rhodesiea R5 accumulate uranium both extracellularly on the cell surface and intracellularly as electron-dense granules.]]></dc:description>

<dc:description><![CDATA[Mechanical and tribological properties of successive C and N ion implantation into Al were studied in the present work. Ion sequence, substrate temperature and subsequent thermal treatment were performed in order to understand the involved mechanisms on the surface hardening. The results showed that independent of the ion sequence, a higher surface hardness is obtained for room temperature ion implantation (≈ 10 GPa). At high substrate temperature the hardness decreases to 7 GPa. The hardening mechanisms are discussed in terms of: solid solution, hard embedded precipitates in the soft Al matrix and the damage produced by the ion implantation process. Adhesive and abrasive regimes are identified from the friction coefficient profiles and are function of the ion implantation parameters. Wear resistance is improved if subsequent thermal treatment at high temperature is performed. Wear improvement is correlated to the presence of a high concentration of carbon clusters in the Al matrix.]]></dc:description>

<dc:title><![CDATA[Experimental Evidence of Si Nanocluster delta-Layer Formation in Buried and Thin SiO<SUB>2</SUB> Films Induced by Ion Irradiation]]></dc:title>
<dc:source><![CDATA[EMRS Spring Meeting, 26.05.2004, Strasbourg, France]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[Self-aligned Si nanocluster (NC) formation in thin MOSFET gate oxides by means of ion beam mixing and post-irradiation annealing of SiO<SUB>2</SUB>-Si interfaces is proven for the first time by cross-section TEM. This study proves a recent prediction based on kinetic Monte Carlo (KLMC) simulations that a delta-layer of tiny Si NCs in SiO<SUB>2</SUB>, located 2…3nm apart from the SiO<SUB>2</SUB>-Si interface, can be fabricated by ion irradiation [1]. Such a self-aligned NC delta-layer configuration meets the requirements of non-volatile multi-dot floating-gate memory transistors [2], on which immense research effort has been spent in recent years.
By conventional TEM techniques the delta-layer of Si NCs in SiO<SUB>2</SUB> can not be observed due to the low mass contrast between Si and SiO<SUB>2</SUB> and the tininess of the Si NCs which have a mean diameter of 1.5nm. Here we present a method of mass contrast enhancement of such tiny Si NCs by alloying them with Ge. For this purpose, a thin Ge layer was embedded into the oxide far above the SiO<SUB>2</SUB>-Si interface, i.e. outside the mixing range of the SiO<SUB>2</SUB>-Si interface in order not to interfere with the original Si NC formation process. During post-irradiation annealing, diffusing Ge atoms are captured by the Si NCs due to the strong Si-Ge bond.]]></dc:description>

<dc:title><![CDATA[Dynamo experiments: where we stand and where we go]]></dc:title>
<dc:source><![CDATA[European Geosciences Union, 1st General Assembly, 25.-30.04.2004, Nice, France]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[It was a nice coincidence that, after years of preparations, the liquid sodium dynamo facilities in Riga and Karlsruhe had become operative nearly simultaneously at the end of 1999. Since those pioneering times, there have been many additional runs in either place, yielding a wealth of reproducible data on the kinematic as well as on the saturated regime. The accompanying numerical work has got some maturity and shows, by now, a reasonable correspondence with the experimental results. The results of the two experiments are complementary rather than redundant as they cover the paradigmatic cases of a large scale dynamo (Riga) and a mean-field dynamo (Karlsruhe). With the main focus on the results and the interpretation of the Riga dynamo experiment, we give a summary of what has been achieved so far and what is left for future dynamo experiments. In particular, we demonstrate that the saturation mechanism of the Riga dynamo experiment is already a non-trivial one as it relies heavily on the change of the flow structure due to the back-reaction of the self-excited magnetic field. We comment on the envisioned dynamo experiments in non-rotating and rotating spheres and ask what geodynamo simulation could learn from
them.

<dc:description><![CDATA[The influence of 30 keV Ga+ ion irradiation on the magnetic properties of polycrystalline NiFe/FeMn exchange bias layers were investigated. In this context, it was of particular interest to determine whether a previously observed enhancement of the bias field value for the irradiation with 5 keV He+ ions is a material-specific or an ion-specific effect. Moreover, the capability of magnetic micropatterning using Ga+ ions from a Focused Ion Beam source was tested. It could be demonstrated that magnetic patterning with a lower limit in the range of 100  1000 nm is possible.]]></dc:description>

<dc:description><![CDATA[An analysis of experimental data consisting of isotopically resolved spallation products from 1 GeV proton-necleus interactions with targets from Fe to Cd is presented. It was found that the yield ratios of isotopes classified by the difference of the neutron numbers are compatible with relations derived in the grand canonical approach. The independence of isotopic temperatures on the target mass was demonstrated for spallation products. An 'unified' isoscaling is proposed which takes into account different nucleonic compositions of the emitting sources. Modified isoscaling parameters are proposed and their physical meaning is discussed.]]></dc:description>

<dc:source><![CDATA[ICNMTA 2010 - 12th International Conference on Nuclear Microprobe Technology and Applications, 26.-30.07.2010, Leipzig, Germany]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Recently, the role of microbial activity in mineral formation has become of great interest. In this case, the question arose for platinumpalladium nuggets recovered from an alluvial deposit (unconsolidated sediments deposited by streams) in the state of Minas Gerais in Brazil [1]. The morphological features of these aggregates of noble metals intuitively suggest that biological processes play a role in the formation of these particles. However, a geochemical fingerprint of microbial activity in precious-metal fixation is lacking. Iodine can provide such a fingerprint because it is a strongly biophile element. However, the detection of iodine at the µg/g level in a heavy matrix is quite challenging.
There are various techniques for the quantitative chemical analysis based on the detection of X-rays. Two of these techniques are PIXE (Particle Induced X-ray Emission) and XRF (X-Ray Fluorescence). In the past, only PIXE could be combined with a focussed ion beam to obtain elemental distribution maps with micrometer lateral resolution. PIXE was performed using a 3 MeV and 2 MeV H<sup>+</sup> beam focussed to about 5x5 µm² coming from a 3 MV Tandetron accelerator at FZD, Dresden [2]. Another possibility is a mobile micro-XRF spectrometer, called MICROTAX or ArtTAX [2], in which X-rays from an X-ray tube are focussed by a polycapillary lens to a spot size of less than 100 µm. Both techniques, PIXE and µ-XRF, failed in detecting any iodine. The best detection limit obtained by PIXE was 70 µg/g for I in this matrix.
Nowadays, Synchrotron Radiation-induced XRF (SR-XRF) can also achieve spot sizes in the micrometer range. The SR-XRF analysis was carried out at the high energy beam line of the BAM, BAMline, at BESSY II. The excitation energy was 40 keV. An ~1 µm² spot size was achieved by focusing with an compound refractive lens CRL [3]. Only SR-XRF succeeded and indicated a significant positive correlation between iodine and palladium concentrations.
The measurements confirm that SR-XRF is very suitable for the detection of trace elements in heavy-metal matrices, which is mainly due to the tunability of the X-ray energy. The results of the SR-XRF measurements suggest that iodine may be used as a tracer for biologically mediated mineral formation.

<dc:source><![CDATA[VAAM 2004, 28.-31.03.2004, Braunschweig, Germany<br>Proceedings]]></dc:source>

<dc:description><![CDATA[Cells of the uranium mining waste pile isolate Bacillus sphaericus JG-A12 are capable of selective and reversible accumulation of  heavy metals.
The cells of B. sphaericus JG-A12 are enveloped by a surface-layer (S-layer). S-layers, which are composed of identical protein monomers with the ability to self-assemble into two-dimensional crystalline arrays, are one of the most commonly observed surface structures of archaea and bacteria.
In case of the strain JG-A12 our analyses showed that the S-layer is capable of binding metals. Thus, it is probable that the S-layer contributes to heavy metal resistance.
Sequence analyses showed, that the S-layer proteins of  B. sphaericus JG-A12 and its closest relative, B. sphaericus NCTC9602,  possess an unusual high identity of the N-terminus and the central domain, whereas  the C-terminal parts differ significantly between the two strains. Further, both strains contain a second truncated S-layer gene-like copy which is possibly encoded by large plasmids. These results indicate a horizontal transfer of parts of the gene between different strains.
The S-layer proteins show a high content of aspartate and glutamate, especially in the C-terminal part. IR analyses demonstrated that the carboxylgroups of these residues are involved in Pd-binding.

<dc:date>2004</dc:date>
<dc:description><![CDATA[Contamination of soils with heavy metals and radionuclides is a severe environmental problem. Bacteria are involved in migration and detoxification of a large number of toxic metals due to their ability to interact with and to biotransform them. Total DNA was extracted from soils of one uranium mining waste pile near the town of Johanngeorgenstadt (Germany) and of one uranium mill tailings near Shiprock, NM in the USA. Universal bacterial, archael and also Geobacter-specific primers were used to construct 16S rDNA libraries. We found that natural microbial communities at the two uranium wastes differed significantly.                         Alpha-Proteobacteria and representatives of the Holophaga/Acidobacterium phylum were predominant in the U mining waste pile, whereas the Shiprock U mill tailings was occupied mainly by Bacillales, Gamma-Proteobacteria and Green non-sulfur bacteria. The most related sequences to ours in the GenBank were those of not yet cultured bacteria or archaea. Representatives of the genus Geobacter were identified in the U waste pile by using Geobacter-specific primers and in the U mill tailings by both Geobacter-specific and universal primers. Because these bacteria are able to reduce and immobilize a large number of heavy metals, we are performing a quantification of them via Real time PCR. Efforts to cultivate some bacterial isolates from the U wastes are in progress in our laboratory.

<dc:date>2004</dc:date>
<dc:description><![CDATA[In the present work the influence of HA on the interaction of tetravalent actinides onto quartz sand was investigated in batch and column experiments. HA can affect the sorption of actinides onto mineral surface as a complexing ligand for cations in solutions, and as an adsorbent by modifying the properties of the mineral surface.
Batch experiments were performed with Th(IV) as stable tetravalent actinide element. Column experiments were carried out with uranium which is less stable in the tetravalent state under laboratory conditions. Results of the U(IV) migration were compared to the U(VI) migration. 
HA shows a pH-dependent influence on the Th(IV) sorption onto quartz sand. At pH < 4 HA may immobilize Th(IV) due to HA sorption and/or precipitation onto the surface. Between pH 4 and pH 5 the Th(IV) sorption is decreased in the presence of HA which can be attributed to the formation of dissolved Th(IV)-humate complexes. For higher pH values a comparable effect is assumed. The experimental proof was not possible by the performed batch experiments. 
From the column experiments it can be concluded that HA affects the migration of both U(IV) and U(VI). In the presence of HA U(VI) is significantly mobilized. A similar effect is supposed for U(IV). This is in accordance with the results of the batch experiments.

<dc:description><![CDATA[Several mental diseases are associated with disorders of the serotonergic neurotransmission.[1] The serotonin transporter (SERT) regulates the synaptic concentration of this neurotransmitter and represents a primary target in the development of antidepressant drugs. Indol-3-yl-cyclo-alkanyl/-alkenyl amines (CnH2n-2(4), n=6,5,3), considered as conformationally constrained analogues of 5-hydroxytryptamine (5-HT, serotonin), have been introduced as a class of candidates holding highly potent SERT inhibitors[.2] In the search for new SERT ligands for PET with improved binding profiles we turned our interest towards rigid structures containing a 1,3-disubstituted cyclobutane (CnH2n-2, n=4), as spacer between the indole moiety and the amino group.
The present work describes our work on the synthesis and biological evaluation of the mono-fluorinated (2a,3a,4a) and double-fluorinated target molecules (1 b,2b).
The carbonyl group of both 3-(2-benzyloxy-ethyl)- and 3-(3-benzyloxy-propyl)cyclobutanone was converted by appropriate steps to yield the N-methyl, N-Boc protected cis- or trans-cyclobutyl amines. After removing the O-benzyl group, the alcohol was oxidized to the aldehyde applying the known TEMPO (2,2,6,6-tetramethyl-1-piperidinyloxy) procedure. The secondary amines (1a-4a) were then directly obtained from the cyclobutyl aldehyde precursor via Fischer indole synthesis; for the tertiary amines 1 b and 2b an N-alkylation of 1 a and 2a with 3-fluoropropyliodide was performed.
Displacement experiments on hSERT-HEK293 cells labeled with [3H]citalopram have shown that cis-derivatives (Ki values: 1 b, 6.74±0.79 nM; 2a, 5.43±0.54 nM; 2b, 6.31 ±1 .37 nM) have nanomolar affinity for human SERT. The trans compound shows somewhat lower affinity (3a, 10.7±1.88 nM). By contrast, parallel studies applying [3H]paroxetine as radioligand indicated significantly lower SERT affinities [90 nM < Ki (1 b,2a,2b,3a,4a) <155 nM]. Thus, potential radiotracers based on the new derivatives may be able to selectively label the citalopram binding site of the SERT.
We have developed a general access to 5-fluoroindol-3-yl cyclobutylamines both in cis(1a, 1b, 2a, 2b) and trans-configuration (3a, 4a) obtained from readily accessible starting materials. Five synthesized compounds (1b, 2a, 2b, 3a, 4a) displayed promising affinities for SERT.]]></dc:description>

<dc:title><![CDATA[EXAFS, XANES, and DFT study of the mixed-valence compound YMn 2O 5: Site-selective substitution of Fe for Mn]]></dc:title>
<dc:source><![CDATA[Physical Review B 82(2010), 014409]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[In YMn2O5 the Mn atoms occupy two non-equivalent Wyckoff sites within the unit cell exhibiting different oxygen coordinations, i. e. the system can be characterized as a mixed-valence compound. For the formation of the orthorhombic crystal structure Jahn-Teller distortions are assumed to play an important role. In this study, we aimed at the investigation of the crystal structure on the substitution of Mn by the non-Jahn-Teller cation Fe+3. Therefore, we synthesized a series of YMn(2-x)FexO5 powder samples with x = 0; 0:5; 1 by a citrate technique. We utilized extended x-ray absorption fine structure (EXAFS), x-ray absorption near edge structure (XANES) analysis and Density Functional Theory to investigate the two non-equivalent Wyckoff sites within the orthorhombic crystal structure (confirmed for all compositions) occupied by transition-metal atoms. For quantitative determination of structural short-range order firstly all plausible options of substitution of Fe for Mn were discussed. On basis of these evaluations the EXAFS and XANES behavior was analyzed and appropriate crystallographic weights were assigned to the subset of structural models in accordance with the experimental data. From EXAFS analysis, using multiple scattering theory, we concluded only the 4h Wyckoff site to be occupied by Fe (occupancy refined was (100 +- 3)% in case of x = 1). Furthermore, taking the XANES spectra into account, we could verify the EXAFS results and additionally explain the differences in the Mn-K XANES spectra in dependence on x to be caused by changes of the dipole transitions to 4p final states. Since only one Wyckoff site is involved the experimentally observed limit to a maximum amount of x = 1 is explained. Additionally, a possible disorder, discussed in the literature, was not proven for our samples. With DFT calculations the experimental findings were verified on base of the total energy of the different possible electronic configurations. Crystal field effects were identified to be responsible for the site selective substitution of Fe for Mn.]]></dc:description>

<dc:description><![CDATA[Recently it could be reported, that uranium can occur in its tetravalent oxidation state on the Surface of roots of Arabidopsis halleri /1/. Nevertheless it is very unusual to find uranium in this oxidation state in soil compartments located close to the earth surface, where oxidizing conditions dominate. The oxidation state +6 should be the stable under these conditions.
Flavonoids are widely distributed in plants and have multifunctional properties. They are known for there antioxidant activity Within this class of compounds quercetin is very widespread.  Considering that quercetin may be involved in the reduction process we carried out experiments to reduce uranium-(VI) by quercetin. The experiments were carried in under N2-atmosphere to avoid reoxidation of the formed uranium-(IV). Under these in vitro conditions quercetin was able to reduce up to 10% of the uranium. Uranium-(IV) was determined directly by Laser-Induced Photoacoustic Spectroscopy and UV-Vis spectroscopy. 
However, this does not explain the existence of uranium-(VI) on the roots. The redox potential of quercetin was measured as function of pH. The shift of the redox potential supports the reduction of uranium with increasing pH /2/. Additionally quercetin can act as complex forming agent. We studied the complex formation of quercetin with uranium-(IV) and uranium-(VI). In both cases a 1:1 complex was found and the stability constants were determined to be log β11 = 20.36 /2/ and log β11 = 13.8 /3/, respectively. This shows a strong stabilization of the uranium-(IV) in its complex with quercetin.

<dc:source><![CDATA[Journal of Applied Physics 101(2007), 103523]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[In this work, we investigate the strain and defect state of silicon implanted with nitrogen by plasma immersion ion implantation, with doses between 4.5 1016 and 8.7 1016 cm 2. For this purpose, we have used Auger electron spectroscopy, x-ray reflectivity, and high-resolution x-ray diffraction. Auger spectra showed that nitrogen concentration profiles broaden and shift deeper into the substrate as the dose increases. High oxygen concentration in the first 20 nm suggested the presence of an amorphous oxide layer at the sample surface, which was confirmed by x-ray reflectivity measurements. Reciprocal space maps revealed a tensile strain perpendicular to the surface, while no in-plane strain was detected. Since no significant diffuse scattering was found, randomly distributed point defects must be predominant in the strained region compared to large displacement field defects such as clusters and dislocations. 2 scans around (004) Bragg reflection were fitted using dynamical theory of x-ray diffraction. The strain profiles obtained from the best fits correlated well with nitrogen concentration depth profiles, signaling interstitial nitrogen as the main source of strain.]]></dc:description>

<dc:description><![CDATA[Changes of surface layer composition produced by ion bombardment of polyethylene and polypropylene samples were studied. These materials are under consideration for load bearing surfaces in biological and technical applications. To improve their tribological properties surface layers are usually modified by ionizing radiation. To study mechanism of transformations induced by ion beam bombardment selected polymers were implanted with H, He and Ar ions to the fluences ranging from 3x1014 to 2x1016 1/cm². RBS and NRA techniques were applied for sample analysis. Important hydrogen release was observed with increasing ion dose and was correlated with the ion stopping power. Another important effect observed was the rapid oxidation of samples, which apparently occurs after exposure of implanted samples to the air. Up to 10 at.% of oxygen can be incorporated in the implanted layer.]]></dc:description>

<dc:description><![CDATA[Biosorption processes of heavy metals and actinides like uranium by fungal cells play an important role in the mobilisation or immobilisation of these elements in nature. Different sorption experiments of U(VI) with Schizophyllum commune at different initial uranium concentrations and therewith connected varying initial uranium speciation showed high uranium sorption capacities in the pH range from 4 to 7. Formed uranium complexes were investigated by means of time-resolved laser-induced fluorescence spectroscopic measurements (TRLFS). The obtained spectra show clearly differences between the emissions properties of the uranium species on fungi and the dissolved uranium species in the initial mineral medium. While the oxidation state of uranium remained unchanged during the sorption process, the uranium speciation changes significantly. Extra- and/or intracellular phosphate groups are the predominant binding places of uranium due to our first spectroscopic results. X-ray absorption fine structure spectroscopic measurements (EXAFS) were performed for a structural characterisation of formed uranium-fungi species and a verification of the TRLFS results.]]></dc:description>

<dc:source><![CDATA[Journal of Nuclear Science and Technology 48(2011), 490-498]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[The paper reports on new developments in the field of measuring techniques for liquid metal flows. We present three variants of a fully contactless electromagnetic flow meter for determining the integral flow rate in a channel flow. Respective test measurements have been performed at a liquid sodium and lead loop, respectively. One of the sensors is of particular interest since its operation does not depend on the electrical conductivity of the liquid metal, hence it is independent on the melt temperature. The Ultrasound Doppler Velocimetry (UDV) determines the velocity profile along the ultrasonic beam, and has the capability to work even through the channel wall. We present measurements obtained in a liquid sodium channel flow. Further, we report on the development of a contactless magnetic tomography of the global flow pattern in liquid metals. This method provides the full three-dimensional mean velocity distribution in a given liquid metal volume.]]></dc:description>

<dc:description><![CDATA[<b>Introduction:</b>  The AMS business is booming: Many low-energy (< 1 MV) facilities, which are fully dedicated for <SUP>14</SUP>C-analysis, are under construction or in funding status. Additionally, medium-energy accelerators such as the British 5 MV-NEC machine at SUERC Glas-gow, the French 5 MV-HVEE-machine ASTER at Aix-en-Provence [1] and the two German 6 MV-HVEE-machines DREAMS at Dresden [2] and Cologne AMS have been recently installed or are still in testing mode in Central Europe. Of course, these bigger machines need not only experienced physicists and technicians to get them running. It also seems to be advisable to have some experienced scientists around, who knows how to prepare AMS targets for <SUP>10</SUP>Be, <SUP>26</SUP>Al, <SUP>36</SUP>Cl, <SUP>41</SUP>Ca, and <SUP>129</SUP>I measurements.
Quality assurance:  In contrast to the <SUP>14</SUP>C-community, where e.g. round-robin exercises are routine business, the idea of quality assurance and traceable standards has only been brought up lately for the other cosmogenic radionuclides. Thus, world-wide accepted standards issued by metrology institutes are rare: NIST is selling two kinds of <SUP>129</SUP>I/<SUP>127</SUP>I-standards, and the Institute for Reference Materials and Measurements (IRMM) provides one set of <SUP>41</SUP>Ca/<SUP>40</SUP>Ca solutions having eight different ratios [3]. Unfortunately, the most commonly used <SUP>10</SUP>Be/<SUP>9</SUP>Be standard provided by NIST has been recently sold-out and will not be reissued. Other primary standard-type materials (<SUP>26</SUP>Al,<SUP>36</SUP>Cl), which are not commercially available, have been prepared by diluting certified activities and subsequent analysis within round-robin exercises [4,5]. After production of big quantities of in-house secondary standards for all nuclides, cross-calibration vs. primary standard-type materials has to be performed in-house and elsewhere [1].
Finally, as commercial <SUP>9</SUP>Be contains intrinsic <SUP>10</SUP>Be up to a level of 4x10<SUP>-14</SUP> [6] sophisticated production of in-house carriers, used as machine blanks and for processing samples, such as Be<SUB>2</SUB>SiO<SUB>4</SUB> originating from a deep mine in Brazil (Fig. 1), is needed.
 
Fig. 1: Origins of terrestrial samples yet processed at FZD chemistry labs: Antarctica, Brazil (carrier), Italy, Macedonia, Nepal, Slovenia, Tajikistan and Turkey.

Only after production and measurement of all these materials, the AMS facility is ready for real sample measurements.
<b>Real samples:</b>  As it is always not advisable to change two important things at the same time, here machine and chemistry, first and foremost, a close cooperation with the AMS teams of ASTER and VERA (Vienna Environmental Research Accelerator) needed to check the quality of the new chemical sample preparation at FZD.
A good AMS sample is defined by two main features: high stable isotope current and low isobar concentration. A high chemical yield and low concentrations of other elements  originating either from the matrix or chemical products used  are less important. A corresponding low processing blank, i.e. with a very low radionuclide/stable nuclide ratio, is, however, essential for projects working near the detection limit. For high sample throughput and reasonable costs a fast, easy and cheap chemical separation is also favorable. Though, as it is the case for most destructive analytical methods, AMS sample preparation takes much longer, i.e. 24 h (ice, water) to 2-4 weeks (sediments, rocks), and is more expensive than the actual AMS measurement [7], which takes about 10-60 min.
For <SUP>10</SUP>Be-AMS-targets isolated from quartz-rich river sediments (Himalaya, erosion rate study) and a calcite-rich boulder from a Slovenian rockfall area, <SUP>9</SUP>Be-currents had been in the range of ASTER standards and machine blanks. The processing blanks produced at FZD were in the same order as the machine blank (1x10<SUP>-15</SUP>), thus, more than one order of magnitude lower than the lowest sample ratio.
Ten <SUP>36</SUP>Cl-AMS-targets prepared from river terraces (Anatolian Plateau, Turkey, uplift rate study) will be investigated in June at VERA, hopefully validating the high quality of <SUP>36</SUP>Cl-AMS targets.
<b>Conclusion:</b>  We successfully started AMS chemistry in 2009 at FZD and are now open to more collaborations with research institutes and universities.

<dc:description><![CDATA[The nuclides <sup>98</sup>Mo and<sup>100</sup>Mo have been studied in photon-scattering experiments by using bremsstrahlung produced from electron beams with energies from 3.2 to 3.8 MeV. Six dipole transitions in <sup>98</sup>Mo and 19 in <sup>100</sup>Mo were observed for the first time in the energy range from 2 to 4 MeV.
A specific feature in both nuclides is the deexcitation of one state with spin J = 1 to the 0<sup>+</sup> ground state as well as to the first excited 0<sup>+</sup> state, which cannot be explained in standard models. We present a model based on one-particle-one-hole excitations, which allows us to deduce the mixing amplitudes for the two 0<sup>+</sup> shape-isomeric states from the experimental ratio of the transition strengths from the J = 1 state to the 0<sup>+</sup> ground state and to the 0<sup>+</sup> excited state.]]></dc:description>

<dc:title><![CDATA[Effects of irradiation on viability, growth, metastatic properties and expression of Eph receptors and their ephrin ligands in human melanoma cells]]></dc:title>
<dc:source><![CDATA[21st Meeting of the European Association for Cancer Research (EACR-21), 26.-29.06.2010, Oslo, Norway]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Background: 
It is accepted that X-ray irradiation influences growth, viability and metastatic potential of tumor cells. Furthermore, it is supposed that tumor cell invasion and metastasis is regulated by Eph receptors and their ephrin ligands. The aim of our study was to investigate the influence of irradiation on cell viability, growth, and metastasis in human melanoma cells and whether this is mediated by dysregulated Eph receptor or ephrin ligand expression.

Material and Methods: 
Primary (Mel-Juso) and metastatic (A375, A2058) human melanoma cell lines were irradiated with 5 or 10 Gy. Up to 7 days after irradiation we examined cell viability (MTT test). At 1 day and 7 days post irradiation we further analyzed cellular growth, motility (scratch assay), adhesion to fibronectin, and migration through a porous membrane. Furthermore, the mRNA expression of 8 different Eph receptors and 6 ephrin ligands was analyzed using RT-PCR.

Results: 
In all cell lines a dose dependent decrease in viability and cell growth for up to 1 week after irradiation was demonstrated. Analysis of metastatic properties 1 day after X-ray showed decelerated scratch closure, slight increase in migration, and increased adhesion to fibronectin in all investigated cell lines. In contrast, 1 week after irradiation we detected faster scratch closure in irradiated primary Mel-Juso cells but unaltered motility in metastatic cell lines and, moreover, decreased migration in primary Mel-Juso cells and, by trend also in metastatic A375 cells. In addition, in Mel-Juso and A375 cells capability to adhere to fibronectin remained elevated. RT-PCR analysis revealed that Eph receptors and ephrins investigated have similar mRNA expression levels in primary and metastatic cell lines, with exception of both EphA2 and ephrinA5 showing enhanced expression in metastatic A375 cells. After irradiation changes in mRNA expression were not 
detected with exception of an increase in EphA2 and EphA3 in A375 cells and ephrins A1 and A5 in A375 and Mel-Juso cells 7 days after treatment.

Conclusion:
Irradiation considerably influences viability and metastatic properties of melanoma cells. The different effects depending on time after irradiation observed suggest an involvement of cell-cell interaction via A-type Eph receptors and ephrins in irradiation-induced metastatic potency of melanoma cells.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The magnetic anisotropy in amorphous soft magnetic CoFeSiB films is modified by He-ion irradiation. A rotation of uniaxial anisotropy depending on the applied field direction in the irradiated areas is observed by magnetometry and complementary domain observation by Kerr microscopy. No significant degradation in magnetic properties relative to the as-deposited state is found from the magnetization loops on non-patterned films. Using irradiation together with photolithography the films were treated locally, resulting in anisotropy patterned structures. Complicated periodic domain patterns form due to the locally varying anisotropy distribution. Overall magnetic properties and domain patterns can be adjusted.]]></dc:description>

<dc:description><![CDATA[In previous experiments, diamond-like carbon (DLC) foils which are being produced at Kurchatov Institute, have proven well suited as long-lived stripper foils for high-energy heavy-ion tandem accelerators and ultra-thin secondary-electron (SE) emitting foils for TOF spectrometers. This paper presents the recent advances in DLC targetry with main emphasis given to development and applications of ultra thin foils (maximum diameter up to 70 mm) with high uniformity and minimal possible effective thickness, the latter has been evaluated by measurements of both energy loss and angular scattering of heavy ions transmitting through the foils. Comparative lifetimes of DLC stripper foils irradiated with high intensity (150 muA) He+ beams at 2 MeV are reported, which demonstrate the favorable use of DLC foils as supplemental strippers at RFQ linacs. In conclusion, the attractive results of application of ultra-thin DLC foils to TOF detectors for heavy ion AMS as well as to compact tandem accelerators are presented.]]></dc:description>

<dc:title><![CDATA[Biodistribution and catabolism of <SUP>18</SUP>F-labeled N-epsilon-fructoselysine as a model of Amadori products]]></dc:title>
<dc:source><![CDATA[Nuclear Medicine and Biology 33(2006), 865-873]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Amadori products are formed in the early stage of the so-called Maillard reaction between reducing sugars and amino acids or proteins. Such nonenzymatic glycosylation may occur during the heating or storage of foods, but also under physiological conditions. N-epslion-fructoselysine is formed via this reaction between the epsilon-amino group of peptide-bound lysine and glucose. Despite the fact that, in certain heated foods, up to 50% of lysyl moieties may be modified to such lysine derivatives, up to now, very little is known about the metabolic fate of alimentary administered Amadori compounds. In the present study, N-succinimidyl-4-[<SUP>18</SUP>F]fluorobenzoate was used to modify N-epsilon-fructoselysine at the a-amino group of the lysyl moiety. The in vitro stability of the resulting 4-[<SUP>18</SUP>F]fluorobenzoylated derivative was tested in different tissue homogenates. Furthermore, the 4-[<SUP>18</SUP>F]fluorobenzoylated N-epsilon-fructoselysine was used in positron emission tomography studies, as well as in studies concerning biodistribution and catabolism. The results show that the 4-[<SUP>18</SUP>F]fluorobenzoylated N-epsilon-fructoselysine is phosphorylated in vitro, as well as in vivo. This phosphorylation is caused by fructosamine 3-kinases and occurs in vivo, particularly in the kidneys. Despite the action of these enzymes, it was shown that a large part of the intravenously applied radiolabeled N-epsilon-fructoselysine was excreted nearly unchanged in the urine. Therefore, it was concluded that the predominant part of peptide-bound lysine that was fructosylated during food processing is not available for nutrition.]]></dc:description>

<dc:title><![CDATA[4D-in-beam-PET für periodisch bewegte Phantome bei Bestrahlung mit einem mitbewegten 12C-Strahl]]></dc:title>
<dc:source><![CDATA[16. Jahreskongress der Deutschen Gesellschaft für Radioonkologie, 03.-06.06.2010, Magdeburg, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Fragestellung
In-beam-PET ist die bislang einzige Methode zur in vivo und in situ Überwachung der Dosisapplikation bei der Ionenstrahltherapie. Sie wurde in einem Pilotprojekt am GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt bei der 12C-Bestrahlung von über 400 Patienten mit unbeweglichen Tumoren im Kopf-Halsbereich erfolgreich eingesetzt. Die geplante Anwendung der Ionenstrahltherapie auf, v. a. atmungsbedingt, intrafraktionell bewegliche Tumoren erfordert eine Erweiterung der in-beam-PET-Datenrekonstruktion. Die Notwendigkeit einer zeitaufgelösten (4D) Auswertung und die Qualität der damit reproduzierbaren Aktivitätsverteilung werden anhand experimenteller Daten dargestellt.

Methodik
Ein PMMA-Phantom wurde mittig im Gesichtsfeld des Doppelkopf-PET-Scanners BASTEI am ehemaligen medizinischen Bestrahlungsplatz der GSI positioniert und senkrecht zur Einstrahlrichtung periodisch (sinusförmig, Amplitude = 10 mm, Periode ≈ 3,5 s) ausgelenkt. Mit einem monoenergetischen 12C-Bleistiftstrahl wurde eine im Bereich des Bragg-Peaks homogene, linienförmige Dosisverteilung parallel zur Bewegungsrichtung im Target appliziert. Für die Bestrahlung wurde ein neuartiges Tracking-System benutzt, welches die Strahlrichtung der aktuellen Phantomauslenkung anpasst. Im Verlauf der Bestrahlung entsteht durch Kernfragmentierungen eine der Dosisverteilung ähnliche +-Aktivitätsverteilung aus v. a. 11C und 15O. Die entsprechende Annihilationsstrahlung sowie die Targetbewegung werden während der Bestrahlung (≈ 85 s) und weitere 5 min danach detektiert. Die gemessenen Ereignisse werden unter Berücksichtigung der Detektoreffektivität und einer Schwächungskorrektur rückprojiziert und mit einer Referenzaktivität aus einer zweiten, identischen Bestrahlung und Aktivitätsmessung jedoch ohne Phantombewegung verglichen. Für eine 4D-Auswertung werden zuerst in einem zusätzlichen Zwischenschritt die Koinzidenzen entsprechend der Bewegungsamplitude oder -phase sortiert und die einzelnen Rückprojektionen werden anschließend zusammengeführt.

Ergebnis
Ohne Berücksichtigung der Phantombewegung ist die Aktivitätsverteilung entlang der Bewegungsrichtung über die Targetgrenzen hinaus verschmiert. Sie weicht im Hochdosisbereich bis zu 22 % von der statischen Referenz ab und die Breite des lateralen 8020%-Aktivitätsabfalls vergrößert sich von 7,6 mm für die Referenz auf 17,2 mm. Bei der 4D-in-beam-PET bleibt diese mit 8,3 mm innerhalb der Fehlergrenzen erhalten und der maximale Unterschied zur Referenz beträgt nur 4 %.

Schlussfolgerung
Bereits bei geringen Bewegungsamplituden ist eine 4D-Rekonstruktion erforderlich, da andernfalls nicht die tatsächlich applizierte Dosisverteilung verifiziert werden kann. Bei genauer Kenntnis des Bewegungsverlaufes reproduziert die vorgestellte 4D-in-beam-PET die Aktivitätsverteilung im Phantom innerhalb statistischer Schwankungen. Weitere Experimente für komplexe Targetgeometrien, Dosisverteilungen und Bewegungsabläufe sind erforderlich.]]></dc:description>

<dc:source><![CDATA[Physical Review C 83(2011), 014317]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[The influence of the quadrupole shape fluctuations on the dipole vibrations in transitional nuclei is investigated in the framework of the instantaneous-Shape Sampling (ISS) Model, which combines the Interacting Boson Model for the slow collective quadrupole motion with the Random Phase Approximation for the rapid dipole vibrations. Coupling to the complex background configurations is taken into account by folding the results with a Lorentzian with energy dependent width (collisional damping CD). 
The low-energy energy portion of the  gamma absorption cross section, which is important for photo-nuclear processes, is studied for the isotop series of  Kr, Xe, Ba, and Sm. The experimental cross sections are well reproduced. The low-energy dipole strength is determined by the Landau fragmentation of the dipole strength and its redistribution caused by the shape fluctuations. CD only wipes out fluctuations of the absorption cross section, generating the smooth energy dependence observed in experiment. In the case of semi magical nuclei, shallow pygmy resonances  are found in correspondence with experiment.]]></dc:description>

<dc:description><![CDATA[Novel indole radiotracers for 123I and 99Tcm labeling were designed. The corresponding reference compounds (Indole-I and Indole-MAMA-Re) and the precursor for 99Tcm labelling were synthesized. The compounds were characterized by IR, NMR, and MS analyses. Competition binding assays in vitro show that the Ki values of Indole-I for σ1 and σ2 receptors are (0.574 ± 0.355) μmol/L and (0.162 ± 0.030 2) μmol/L, respectively. The Ki values of Indole-MAMA-Re for σ1 and σ2 receptors are (3.75 ± 2.22) μmol/L and (7.83 ± 4.87) μmol/L, respectively. Furthermore, 99Tcm-Indole-MAMA was successfully prepared. The radio-chemical purity (RCP) of 99Tcm-Indole-MAMA after purification was higher than 90% by  HPLC analysis. The compounds reported in this paper may be used as lead compounds for further structural modification to develop indole SPECT tumor imaging agents.]]></dc:description>

<dc:description><![CDATA[Superjunction devices (SJDs) are a novel class of power devices which break the physical limit of silicon with respect to the area specific turn-on-resistance. SJDs consist of a modified vertical MOSFET structure which is characterized by additional deep pillar-like p-type regions formed inside the n(-) epi-layer below the transistor gate. In the present investigation ultra-high energy boron ion implantation of 2-25 MeV were applied for forming the deep p-type regions laterally structured using Si stencilmasks. For energies above 12 MeV the incident ions exceed the Coulomb barrier for Si which leads (i) to a significant gamma and neutron emission during implantation and, (ii) an activation of the wafer and the mask material. Fortunately, the most relevant reaction (11B+28Si >n,alpha>34mCl> 34S+beta) has a half-life time of only 32 min so that the radiation level of the wafers drops below the critical radiation protection limit within the processing time. Based on the described technology Infineon Technologies successfully prepared a set of prototype wafers with fully functional high-voltage transistors. Typical blocking capability was in the range of 560 V with an on-state resistance of about 185 mOhm.]]></dc:description>

<dc:title><![CDATA[The superconducting RF photoelectron source for the ELBE accelerator at Rossendorf]]></dc:title>
<dc:source><![CDATA[ANKA Seminar, 08.02.2010, Karlsruhe, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Most of the proposed electron accelerator projects for future FELs, ERLs, or 4th generation light sources require electron beams with an unprecedented combination of high-brightness, low emittance and high average current. The ideal candidate for it is the superconducting RF photogun (SRF gun) which can be easily operated in CW like a DC photogun and may reach the beam quality of a normal conducting RF photogun. Challenges are the design of the superconducting cavity, the choice of the photocathode type, its life time, a possible cavity contamination, the difficulty of coupling high-average power into the gun and finally the risk of beam excitation of higher order cavity modes. At the FZ Dresden-Rossendorf a SRF gun has been developed and installed at the ELBE superconducting linac. The SRF gun is designed for an average current of 1 mA and an maximum electron energy of 9 MeV. The 1.3 GHz cavity consists of three full cells with TESLA geometry, a specially designed half-cell where the photocathode is placed. The photocathode with a Cs2Te photoemission layer is normal-conducting and cooled by liquid nitrogen. In the talk an overview of the technical concept, the RF properties, the photo cathode development, and beam parameter measurements will be given.]]></dc:description>

<dc:source><![CDATA[Applied Radiation and Isotopes 69(2011), 852-857]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[Aim. 
Labeling of specific monoclonal antibodies or their fragments with suitable radionuclides can be utilized for diagnosis of autoimmune disorders or in preclinical research for elucidation of the role of specific cell types in underlying disease pathophysiology. In contrast to other radionuclides, <SUP>89</SUP>Zr as a marker for positron emission tomography (PET) and protocols for <SUP>89</SUP>Zr production so far have found relatively little interest despite the many advantages of this radionuclide. 
Methods. 
We examined the production, separation, and characterization of <SUP>89</SUP>Zr, including supplementation of a commercial Cyclone<SUP>®</SUP> 18/9 with a self-made Solid Target System (STS) and the construction of a re-usable target holder. Optimized conditions to reduce undesired long-lived side products were specified. Obtained [<SUP>89</SUP>Zr]Zr-oxalate was used for labeling of anti-B cell antibodies with desferrioxamine-p-SCN as a bifunctional chelator. <SUP>89</SUP>Zr-labeled antibodies were injected in DBA/1 mice to examine usability for detection of B cells in vivo by PET.
Results. 
The improved conditions yielded <SUP>89</SUP>Zr of high purity with smaller amounts of long living <SUP>88</SUP>Zr isotope compared to other methods. The antibody labeling procedure yielded crude mixtures containing non-chelated metal, which were separated using desalting columns. Analytical radio-HPLC and TLC revealed <SUP>89</SUP>Zr-labeled antibodies of sufficient purity. PET measurements showed binding of <SUP>89</SUP>Zr-labeled anti-B cell antibodies in tissues with high frequencies of B cells, i.e. in spleen and lymph nodes.
Conclusion. 
Labeling of antibodies directed to specific cell types with <SUP>89</SUP>Zr according to our protocol turned out to be an effective tool for in vivo visualization and tracking of cells in mice by immuno-PET.]]></dc:description>

<dc:source><![CDATA[Radiochimica Acta 99(2011), 775-782]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[The formation of aqueous Cm(III) phosphate complexes was studied at room temperature by time-resolved laser-induced fluorescence spectroscopy (TRLFS) in 0.1 M NaClO<sub>4</sub> solutions. The experiments were perfomed at a fixed total Cm(III) concentration of 3x10<sup>-7</sup> or 2x10<sup>-8</sup> M by varying the phosphoric acid concentration (3x10<sup>-5</sup> - 0.1 M) and the pH (1.4 - 6.0). The red shift of the excitation and emission spectra, as well as the increase of luminescence lifetimes clearly showed the influence of phosphate on the aqueous Cm(III) speciation. In acidic phosphate solutions ([H<sub>3</sub>PO<sub>4</sub>] < 0.1 M, pH 1.4 - 2.6) an increase in luminescence intensity was detected due to complexation with H<sub>2</sub>PO<sub>4</sub> -. At [H<sub>3</sub>PO<sub>4</sub>] > 4x10<sup>-4</sup> M and between pH 4.0 and 6.0 in general a decrease in luminescence intensity affiliates the complexation with HPO<sub>4</sub><sup>2-</sup>. Two Cm(III)-phosphate complexes could be identified from the emission data, CmH<sub>2</sub>PO<sub>4</sub><sup> 2+</sup> and CmHPO<sub>4</sub><sup>+</sup>, having peak maxima at 599.6 and 600.8 nm, respectively. TRLFS in combination with ultra-filtration (1 kD) showed that the formation of CmHPO<sub>4</sub><sup>+</sup> is affiliated by the generation of Cm(III)-phosphate colloids especially at [H<sub>3</sub>PO<sub>4</sub>] > 0.002 M and pH > 5. Cm(III)-phosphate colloids formed at pH 5 and 6 are characterized by an emission maximum at 603.1 nm. Based on the factor analysis of the emission data the stability constants of the two complexes were calculated to be log ß<sub>121</sub> = 20.23 ± 0.13 and log ß<sub>111</sub> = 16.54 ± 0.80 at an ionic strength of 0.1 M (NaClO<sub>4</sub>).]]></dc:description>

<dc:description><![CDATA[The extreme versatility of dendrimers makes them attractive for drug delivery applications. In this perspective, binding of potential drug molecules non-covalently at the interior of dendritic hosts seems to be the most appropriated strategy. We have established glycodendrimers with dense maltose shell which may be utilized to encapsulate nanometer sized guest molecules. <SUP>[1]</SUP> This is of particular interest since it has been shown that polynuclear cluster compounds have antitumoral as well as antiviral properties. <SUP>[2]</SUP>

The encapsulation and release of an anionic rhenium cluster complex [Re<SUB>6</SUB>S<SUB>8</SUB>(OH)<SUB>6</SUB>]<SUP>4- [3]</SUP> in biocompatible maltose-decorated dendrimers (generation 4 and 5) have been studied in detail applying different physico-chemical methods, e.g. UV/vis, time-resolved laser-induced fluorescence spectroscopy, laser induced liquid bead ion desorption mass spectrometry and dynamic light scattering measurements. On average, 4  5 cluster anions can be captured in the interior of sugar-coated dendrimers, and a slow release of cluster complexes was observed under physiological conditions.

The encapsulation and release properties of maltose-decorated nanocarriers imply the possibility for the development of the next generation dendritic hosts with targeting moieties.

<dc:source><![CDATA[Wissenschaftlich-Technische Berichte / Helmholtz-Zentrum Dresden-Rossendorf; FZD-535 2010<br>ISSN: 1437-322X]]></dc:source>

<dc:description><![CDATA[The migration behavior of actinides and other radioactive contaminants in the environment is controlled by prominent molecular phenomena such as hydrolysis and complexation reactions in aqueous solutions as well as the diffusion and sorption onto minerals present along groundwater flow paths. These reactions significantly influence the mobility and bioavailability of the metal ions in the environment, in particular at liquid-solid interfaces.
Hence, for the assessment of migration processes the knowledge of the mechanisms occurring at interfaces is crucial. The required structural information can be obtained using various spectroscopic techniques.
In the present study, the speciation of uranium(VI) and neptunium(V) at environmentally relevant mineral  water interfaces of oxides of titania, alumina, silica, zinc, and alumosilicates has been investigated by the application of attenuated total reflection Fouriertransform infrared (ATR FT-IR) spectroscopy. Moreover, the distribution of the hydrolysis products in micromolar aqueous solutions of U(VI) and Np(V/VI) at ambient atmosphere has been characterized for the first time, by a combination of ATR FT-IR spectroscopy, near infrared (NIR) absorption spectroscopy, and speciation modeling applying updated thermodynamic databases.
From the infrared spectra, a significant change of the U(VI) speciation is derived upon lowering the U(VI) concentration from the milli- to the micromolar range, strongly suggesting the dominance of monomeric U(VI) hydrolysis products in the micromolar solutions. In contradiction to the predicted speciation, monomeric hydroxo species are already present at pH ≥ 2.5 and become dominant at pH 3. At higher pH levels (> 6), a complex speciation is evidenced including carbonate containing complexes.
For the first time, spectroscopic results of Np(VI) hydrolysis reactions are provided in the submillimolar concentration range and at pH values up to 5.3, and they are comparatively discussed with U(VI). For both actinides, the formation of similar species is suggested at pH ≤ 4, whereas at higher pH, the infrared spectra evidence structurally different species. At pH 5, the formation of a carbonate-containing dimeric complex, that is (NpO2)2CO3(OH)3^-, is strongly suggested, whereas carbonate complexation occurs only under more alkaline conditions in the U(VI) system.
The results from the experiments of the sorption processes clearly demonstrate the formation of stable U(VI) surface complexes at all investigated mineral phases. This includes several metal oxides, namely TiO2, Al2O3, and SiO2, serving as model systems for the elucidation of more complex mineral systems, and several alumosilicates, such as kaolinite, muscovite and biotite. From a multiplicity of in situ experiments, the impact of sorbent characteristics and variations in the aqueous U(VI) system on the sorption processes was considered.
A preferential formation of an inner-sphere complex is derived from the spectra of the TiO2 and SiO2 phases. In addition, since the in situ FT-IR experiments provide an online monitoring of the absorption changes of the sorption processes, the course of the formation of the U(VI) surface complexes can be observed spectroscopically. It is shown that after prolonged sorption time on TiO2, resulting in a highly covered surface, outer-sphere complexation predominates the sorption processes. The prevailing crystallographic modification, namely anatase and rutile, does not significantly contribute to the spectra, whereas surface specific parameters, e.g. surface area or porosity are important.
A significant different surface complexation is observed for Al2O3. The formation of innerspheric species is assumed at low U(VI) surface coverage which is fostered at low pH, high ionic strength and short contact times. At proceeded sorption the surface complexation changes. From the spectra, an outer-spheric coordination followed by surface precipitation or polymerization is deduced. Moreover, in contrast to TiO2, the appearance of ternary U(VI) carbonate complexes on the γ-Al2O3 surface is suggested.
The first results of the surface reactions on more complex, naturally occurring minerals (kaolinite, muscovite and biotite) show the formation of U(VI) inner-sphere sorption complexes. These findings are supported by the spectral information of the metal oxide surfaces.
In this work, first spectroscopic results from sorption of aqueous Np(V) on solid mineral phases are provided. It is shown that stable inner-sphere surface species of NpO2 ^+ are formed on TiO2. Outer-sphere complexation is found to play a minor role due to the pH independence of the sorption species throughout the pH range 4  7.6. The comparative spectroscopic experiments of Np(V) sorption onto TiO2, SiO2, and ZnO indicate structurally similar bidentate surface complexes.
The multiplicity of IR spectroscopic experiments carried out within this study yields a profound collection of spectroscopic data which will be used as references for future investigations of more complex sorption systems in aqueous solution. Furthermore, from a methodological point of view, this study comprehensively extends the application of ATR FT-IR spectroscopic experiments to a wide range in the field of radioecology. 
The results obtained in this work contribute to a better understanding of the geochemical interactions of actinides, in particular U(VI) and Np(V/VI), in the environment. Consequently, more reliable predictions of actinides migration which are essential for the safety assessment of nuclear waste repositories can be performed.]]></dc:description>

<dc:description><![CDATA[The volume fraction of martensite continuously increases with the fatigue cycle number. Consequently, the martensite amount can be used for indication of the low cycle fatigue state. Following an exponential decay function, the martensite volume fraction decreases with increasing temperature. No influence of the load frequency was found. The initial material state plays an important role for the martensite formation rate. The amount of martensite formed is much higher after cold-rolling than after solution annealing as final manufacturing process. The martensite shows a fibre texture in the annealed material. The (I 10) planes are preferentially oriented parallel and perpendicular to the loading direction. In the cold-rolled material no significant preferred orientation of this phase was found. The martensite is concentrated in the centre of the specimens. The shape of the distribution seems to be independent on the martensite amount.]]></dc:description>

<dc:description><![CDATA[Chromium oxynitride films CrOxNy were prepared by reactive magnetron sputtering from a chromium target in Ar/O-2(N2O)/N-2 gas mixtures. The argon-to-nitrogen partial pressure ratio and the DC discharge power were kept constant in the experiments. By changing the gas composition the film stoichiometry can be continuously varied from CrN to Cr2O3. The film composition has been determined by Rutherford backscattering (RBS) and by elastic recoil detection analysis (ERDA). From an XRD analysis it was concluded that the films consist of CrN nanocrystals in an amorphous oxide matrix. Depending on the oxygen content [O], the electronic behaviour of the films changes, accompanied by the evolution of an optical band gap, which was determined by spectral transmission and reflection measurements. The (negative) temperature coefficient at approximate to 300 K of the resistivity of the films is in the range of 0.5 (CrN) to 2% K-1 (CrO0.5N0.7). This film property can be used for temperature-dependent resistors, for instance in thermal radiation detectors.]]></dc:description>

<dc:title><![CDATA[A limited-angle CT approach for a fast scanned electron-beam X-ray tomography with application to multi-phase flow measurements]]></dc:title>
<dc:source><![CDATA[4th World Congress on Industrial Process Tomography, 05.-08.09.2005, Aizu, Japan]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[We devised and tested a computed tomography approach that utilises a scanned electron beam X-ray source to produce multiple projections of an object at scan rates of 1000 frames per second and at an in-plane resolution of 1 mm. The measurement setup consists of an electron beam unit, a cylindrical tungsten target, and a detector line array which are operated inside a vacuum enclosure. By means of fast periodic electron beam deflection we produce a linearly moving focal X-ray spot on the tungsten target. The X-ray detector is read out in synchronisation with the beam deflection signal such that a set of consecutive tomographic projections from an object that is placed between target and detector can be obtained. This approach has some attractive features: it gives the highest achievable axial resolution, which is necessary to image fast moving flow structures and it is comparatively moderate in effort and costs. However, these advantages are compromised by the fact, that the projection data is incomplete with regard to the projection angle. The arising limited-angle problem may be solved by iterative image reconstruction algorithms. We will show, that this approach is suitable for a certain class of flow problems which are characterised by less complex object distributions and a high degree of available a-priori information, such as two-phase flows and particle tracking problems. In the presentation we will give an overview on the method, present first experimental results and discuss the image reconstruction process in some more detail.]]></dc:description>

<dc:source><![CDATA[Nanotechnology 21(2010)38, 385703]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[An approach for tailoring the magnetic properties by ion irradiation of granular perpendicular CoCrPt:SiO2 films grown on silica particles with sizes down to 10 nm was investigated. The as-prepared samples reveal an intriguing scaling dependence of the coercive field and remnant magnetization: both parameters are found to decrease with decreasing particle size. However, Co+ irradiation at a low fluence of 0.5 x 10<sup>14</sup> cm<sup>-2</sup> already results in an opposite scaling behavior. It is assumed that this modification is due to the enhancement of the intergranular magnetic exchange coupling of the granular CoCrPt:SiO2 film initiated by Co+ irradiation resulting in a modified reversal behavior. Further increase of the irradiation fluence beyond 1.6 x 10<sup>14</sup> ions cm<sup>-2</sup> leads to a degradation of the magnetic layer properties, lowering the remnant magnetization and the coercive field in the easy-axis direction. Moreover, the local magnetic properties of the samples were analyzed by magnetic force microscopy revealing magnetic multi-domain cap structures.]]></dc:description>

<dc:description><![CDATA[Si nanocrystals for multi-dot floating-gate memories have been produced by non-conventional ion beam synthesis (IBS). Due to ion beam mixing irradiation with 1015-1016 Si+ cm-2 at 50-100 keV through 50 nm poly-Si and 15 nm SiO2 on (001)Si results in a considerable Si excess within the oxide. At the upper and lower interfaces of the gate oxide, this ion irradiation forms a metastable SiOx (x < 2) composition. Post-irradiation RTA thermal treatment leads to phase separation into Si and SiO2. Adjacent to the recovering interfaces, narrow SiO2 zones become denuded of excess Si. More distant excess Si precipitates as Si NCs in the gate oxide. MOSFET characteristics in terms of write/erase voltage, duration of the programming time, endurance and retention have been evaluated. ]]></dc:description>

<dc:description><![CDATA[Magnetic fields allow to study distinct magnetic effects in various electrochemical systems. Lorentz forces can be utilized to tailor convection and mass transfer in electrolytic cells, thereby influencing for example the morphology and the structure of the electrodeposits [1]. Recently, the influence of magnetic gradient forces on the preparation of microstructured metal deposits on field-gradient electrodes has been discussed in the literature [2]. The presentation summarizes new experimental results, analytical findings and numerical simulations in order to discuss the influence of different magnetic forces involved and the prospects towards smaller deposition structures.

<dc:source><![CDATA[Advanced Spectroscopy and Microscopic Characterisation Techniques - Tools to Enlighten Biogeochemical Interfaces in Soils, 04.-06.10.2010, Jena, Deutschalnd]]></dc:source>

<dc:description><![CDATA[Positron-Emission-Tomography (PET) enables direct and quantitative monitoring of the spatio-temporal distributions of dissolved inert and/or reactive PET-nuclides and PET-nuclide-labelled compounds during their passage through decimetre-scaled material samples. We apply PET exclusively to geological samples and reach the physical resolution limit of about 1 mm with our small-animal-PET scanner (ClearPET, Raytest). We suggest our GeoPET has unrivalled sensitivity and selectivity for tracer concentrations to some 107 tracer atoms/µl and thus is ideally suited for direct flow and transport process observations in soils. This lower limit of the tracer concentration in the order of about 1 kBq/µl outranges other process observation methods (e.g. NMR or resistivity tomography) by many orders of magnitude. Like in the common medical practice, a combination with µCT for structural imaging would be advantageous for improving the spatial significance.
In the past we demonstrated the feasibility of the method, applying in-house developed and medical PET-scanners. The installation of the PET scanner in our controlled area makes possible long-term experiments and the application of non-standard and long-living PET-nuclides (like 124I, decay time 4 days, and 58Co, decay time 71 days). The installation of a new cyclotron will also extend the availability of short-living PET-isotopes for fast process observations (e.g. 11C, decay time 20 min). Application of these nuclides extends the common radiopharmaceutical practice of labelling organic compounds with 18F (decay time 110 min).
The density of geomaterials may cause more than 50% of Compton-scattered events, which degrade the image quality. The quantification of the resulting artefacts is under way by Mont-Carlo model-based tools and will significantly empower the scatter-correction procedures.
Transport observation studies have been conducted on consolidated, partially fractured rocks and on soils, often showing more or less localized transport pathways. The effective volume and transport network, as well as the effective surface area for specific process conditions can be derived directly and quantitatively from the spatio-temporal tracer distribution in the sample, which can be visualized as 3D-movie, in contrast to indirect observations based on break-through curves at the endpoint of the sample. Comparisons with Lattice-Boltzmann simulations based on structural information obtained by µCT are indicating, that any actual transport field very much depends on elusive boundary conditions and therewith represents just one instance of a variety of possible spatio-temporal distributions with similar effective parameters.]]></dc:description>

<dc:description><![CDATA[In order to study the role of the exchange interaction at and near the interface, Ni81Fe19/Fe50Mn50 bilayers have been studied, which have an intervening layer of varying thickness and position in the antiferromagnetic Fe50Mn50 layer. The role of the intervening layer is to generate partial exchange decoupling. As a result, samples were obtained, where in one in-plane direction the position of the intervening layer varies from the interface to the top surface of the Fe50Mn50 layer at a constant intervening layer thickness, and in the other in-plane direction the intervening layer thickness varies. Two-dimensional maps of the resulting exchange bias field and the coercive field were obtained from magneto-optic Kerr effect magnetometry measurements. The role of the position and strength of the partial decoupling within the antiferromagnetic layer on the exchange bias effect and the coercive field is discussed.]]></dc:description>

<dc:source><![CDATA[Physical Review C 72(2005), 035206]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[We analyze an effect of the coherent Theta+Lambda(1520) photoproduction in gamma D interaction near the threshold. We demonstrate that the coherence effect becomes manifest in a comparison of the nK+ invariant mass distribution when the pK- invariant equals the Lambda(1520) mass. Our model calculations indicate a sizeable contribution of resonant and non-resonant background processes in the gamma D to np K+K- reaction which generally exceed the contribution of the coherent resonant channel. However, we find that the coherent Theta+Lambda(1520) photoproduction is enhanced relative to the background processes in the forward hemisphere of the pK- pair photoproduction. Moreover, the coherence effect does not depend on the Theta+ photoproduction amplitude and is defined by the probabilities of the Lambda(1520) photoproduction and the Theta+ to NK transition. Therefore, this coherence effect may be used as an independent method for studying the mechanism of Theta+ production and Theta+ properties.]]></dc:description>

<dc:description><![CDATA[Ferritic/martensitic ODS-steel has been proposed as one of the best candidates as structural materials to be located in future fusion reactors, i.e. ITER and DEMO. One of the points of concern in further material development for fusion applications is the study of the diffusion and/or retention of light atoms, like H, which can be produced by transmutation. In this work, we investigated the chemical composition as well as the H distribution for H as-implanted and post-implanted annealed ODS-steel samples by means of simultaneous µ-PIXE and µ-ERD measurements. In general, µ-PIXE data evidence a quite inhomogeneous distribution of yttrium in some of the samples. It has been found that those regions with a larger Y content correspond with iron- and chromium- depleted regions. The possible correlation between Y and H content is discussed, on the basis of a large H diffusion even at room temperature.]]></dc:description>

<dc:title><![CDATA[Structure and dielectric function of two- and single-domain ZnO epitaxial films]]></dc:title>
<dc:source><![CDATA[Journal of Applied Physics 102(2007), 113505]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[The differences between two- and single-domain ZnO epitaxial films, grown by reactive pulsed magnetron sputtering, have been studied with respect to their texture development and x-ray coherence length behavior at various substrate temperatures and oxygen partial pressures. The film in-plane ordering depends on the surface pretreatment of the sapphire substrate. After pretreatment in an oxygen radio-frequency plasma, single-domain films form even at a substrate temperature of 100 degrees C in a wide range of oxygen pressures, and at a growth rate up to 1.2 nm/s. The single-domain films show a linear dependence of the x-ray coherence length on the substrate temperature, while a steplike dependence is characteristic of the two-domain films. The ZnO complex dielectric function was obtained using a parametrized semiconductor oscillator model for spectroscopic ellipsometry data analysis. For the films grown at 550 degrees C, the band gap of 3.29 +/- 0.01 eV is independent of the type of in-plane ordering and variation of the texture. The oscillator broadening correlates with the width of (0002) diffraction peak rocking curve. Both parameters increase at high oxygen pressure and low substrate temperature, which is attributed to a higher defect (dislocation) density.]]></dc:description>

<dc:description><![CDATA[For the long-term performance assessment of nuclear waste repositories, knowledge concerning the interactions of actinide ions with mineral surfaces is imperative. The mobility of released radionuclides is strongly dependent on the sorption/desorption processes at mineral surfaces and their incorporation into the mineral frame. Hydrous iron oxides (ferrihydrite) are globally of great importance in the environment. Upon heating pure ferrihydrite converts to crystalline goethite and hematite. In the presence of di- or trivalent metal ions the transformation is affected leading to the promotion of one crystal formation over the other and incorporation of these ions. This Study deals with the question if released Am(III) can be immobilized by sorption onto 6-line-ferrihydrite. Moreover it is studied what happens if ferrihydrite transforms to a more crystalline phase.]]></dc:description>

<dc:description><![CDATA[Five fragments of ancient gold objects belonging to Pietroasa Cloşca cu Puii de Aur (The Golden Brood Hen with Its Chickens) Romanian hoard were analyzed using the micro-PIXE (Particle Induced X-ray Emission) technique. The purpose of the study was to gain some more knowledge regarding the metal provenance by determining the presence of PGE (Platinum Group Elements) and other high-temperature melting point trace elements (Ta, Nb, Cr) at a micrometric scale. Ta and Nb inclusions (micrometeric areas of composition different from the surroundings) on two samples and Pd inclusions on one sample were found. The measurements led to some conclusions for the possible gold ore sources of Pietroasa treasury: the South-Ural Mountains, Nubia (Sudan) and/or Anatolian deposits and Roman imperial coins.]]></dc:description>

Two modes with asymmetric (with respect to the hnu =gµ<sub>B</sub>B line) frequency-field dependences are resolved, illuminating the striking incompatibility with a simple uniform S= 1/2 Heisenberg chain model. The unusual ESR spectrum is explained in terms of the recently developed theory for S= 1/2 chains, suggesting the important role of next-nearest-neighbor interactions in this compound.

<dc:description><![CDATA[Bezüglich eines hypothetischen Kernschmelzeszenarios in einem Leichtwasserreak-tor (LWR) ist es notwendig, mögliche Versagensformen des Reaktordruckbehälters sowie Versagenszeiträume zu untersuchen, um die Belastung für das Containment bestimmen zu können. Es wurden bereits eine Reihe von Experimenten durchge-führt, welche Erkenntnisse hierüber liefern sollen. 
Vom Institut für Sicherheitsforschung des FZR wurde ein Finite-Elemente-Modell er-stellt, das sowohl die Temperaturfeldberechnung für die Wand als auch die elasto-plastische Mechanik der Behälterwand beschreibt. Dabei wurde ein fortgeschrittenes Modell für das Kriechen und für die Materialschädigung entwickelt und an Hand von experimentellen Daten validiert. Die thermischen und mechanischen Berechnungen sind rekursiv und sequentiell gekoppelt. Das Modell ist in der Lage, Versagenszeit und Versagensposition eines Behälters mit beheiztem Schmelzepool zu berechnen.
Das Modell wurde für Voraus- und Nachrechnungen der FOREVER-Experimente, die den RDB eines LWR im Maßstab 1:10 nachbilden, angewendet. Diese Experimente wurden an der KTH Stockholm durchgeführt. Die Ergebnisse der Berechnungen sind qualitativ und quantitativ sehr zufriedenstellend.
Erste Rechnungen für eine LWR-Geometrie wurden durchgeführt, um Unterschiede und Gemeinsamkeiten zwischen prototypischen Szenarien und skalierten Experi-menten herauszuarbeiten.

<dc:description><![CDATA[The so called double-heterogeneity, characterizing High Temperature Gas cooled Reactors (HTGR) block type fuel elements, presents a challenge for existing deterministic lattice codes that were originally developed for LWR applications. A large number of TRISO particles randomly dispersed in the fuel compact introduces an additional complexity into the modeling. The Monte Carlo (MC) based codes, which are capable of simulating complex geometries of HTGR fuel elements, are mainly used for the reference calculations. The use of MC codes as production tools for a few-group cross section generation for 3D nodal codes is still very limited due to the high computational costs.
Recently a new few-group cross section generation methodology for a full core analysis of HTGRs was proposed. This methodology is based on homogenization approach called Reactivity equivalent Physical Transformation (RPT). The RPT methodology combines high spatial resolution of MC codes with superior computational speed of deterministic lattice codes. At the first stage, a MC code is used to simulate an HTGR fuel element with explicitly described TRISO particles at the beginning of life (BOL) and at the nominal operational conditions. At the second stage the TRISO particles are homogenized with the fuel compact graphite to get rid of double-heterogeneity problem. It is well known that a simple volume-weighted homogenization of TRISO particles in the graphite matrix results in the underestimation of the self-shielding effect. However, according to the RPT approach, TRISO particles are homogenized in a smaller central volume rather than in entire fuel compact. The volume of the smeared region is adjusted in such way that k-inf of homogenized geometry matches that of the reference heterogeneous one obtained from MC reference calculations. Since the radius of the smeared zone was determined at the beginning of life (BOL) it is kept constant and is used for depletion and branch-off calculations by lattice codes.
The main disadvantage of the RPT approach is the fact that TRISO particles are smeared together with the compact graphite and constitute one homogeneous material. Keeping in mind that the fuel and graphite temperatures may significantly vary during the reactor operation, these temperatures should be decoupled during a few-group cross section generation. However in the majority of lattice codes temperatures are assigned to the regions (e.c. HELIOS code) or to the homogeneous materials (e.c. CASMO code) rather than to particular nuclides like in the MC codes. In order to overcome this disadvantage the RPT methodology has been modified in a way that only TRISO particles are smeared in the central compact region while all compact graphite is concentrated in the remained outer compact region. This modification allows assigning different temperatures to the fuel and as well as to the compact matrix graphite.
The main objective of this study is to verify the modified RPT methodology. A set of depletion calculations of a prismatic block-type HTGR fuel lattice of fuel and coolant channels was performed. Two models of prismatic fuel assembly are considered: 1) 3D model with explicitly described TRISO particles; 2) 2D model, in which TRISO particles are homogenized using the modified RPT approach. 3D calculations are performed with MCNP based depletion code BGCore. 2D calculations are carried out with BGCore code and deterministic lattice code HELIOS 1.9. The comparison between 3D and 2D results is reported. Conclusions regarding validity of modified RPT approach are drawn.]]></dc:description>

<dc:description><![CDATA[The so called double-heterogeneity, characterizing High Temperature Gas cooled Reactors (HTGR) block type fuel elements, presents a challenge for existing deterministic lattice codes that were originally developed for LWR applications.

<dc:description><![CDATA[Strain analysis of a laterally patterned Si-wafer was carried out utilizing X-ray grazing-incidence diffraction performed at the ID10B at the ESRF. The lateral patterning was done by focused ion beam implantation using a AuGeSi alloy liquid metal ion source. Samples were prepared by either a 35 keV Au+ ion beam (dose: 0.3, 2 ·10E14cm−2) or by a 70 keV Ge++ ion beam (dose: 8 · 10E14cm−2). It was shown that a periodical defect structure consisting of both implanted and not implanted stripes is created due to ion beam implantation. The induced strain distribution induced, however, shows no periodicity. This can be only explained by an overlap of the strain fields created in each implanted stripe. We found a maximum strain for the Au implanted samples in a depth of about 20 nm (da/a = −1,−3 · 10E−4 for the Au samples); for the Ge sample in a depth of  100nm (da/a = −1.2 · 10E−4). At depths 500nm below the sample surface the strain of the Ge sample becomes smaller than the detection limit (da/a < 2 · 10E−5). Using this technique we were able to create a buried Ge layer with a thickness of about 200 nm and an averaged Ge content of about 1%.]]></dc:description>

<dc:description><![CDATA[Small-angle neutron scattering experiments have been performed on a homogeneously deformed specimen (uniform elongation 18.5%) of commercial thin-sheet wrought aluminium alloy AA 6013 (Al-Mg-Si-Cu) aged at room temperature. Comparisons with undeformed material revealed characteristic deformation-induced anisotropy of the two-dimensional X-ray and neutron scattering pattern, which can be interpreted as being due to deformation-induced arrangements of preferentially aligned dislocation segments. The results turn out to be helpful for the understanding of anisotropic small-angle X-ray scattering patterns obtained from the crack-tip plastic zone of cracked specimens of the aluminium alloy AA 6013 tempered at 190°C to maximum hardness.   ]]></dc:description>

<dc:description><![CDATA[In order to improve the microstructure of casting ingots a rotating magnetic field (RMF) is widely used to stir the liquid phase during solidification. Usually, the interaction between the solidification process and the RMF driven flow has been discussed only in terms of the flow pattern well-known from the laminar, isothermal case being a superposition of a primary swirling flow in azimuthal direction and a secondary flow occurring as a double vortex in the r-z plane. Effects arising from the propagation of the solidification front, the extension of the mush zone or the spin-up of the flow at higher cooling rates are almost not taken into account. We present experimental and numerical investigations concerning the influence of a RMF driven flow on the momentum, heat and mass transfer within a binary Sn-Pb alloys solidified directionally. 
Solidification experiments were carried out using a Sn-15wt%Pb alloy in a cylindrical mold positioned on a water-cooled copper chill. The ultrasound Doppler velocimetry (UDV) was applied to measure the bulk flow during solidification. The temperature field was monitored using thermocouples. The set-up was enclosed by an inductor providing the RMF. The Taylor numbers Ta were varied between 10e5 and 10e8. 
The continuum formulation based model has been adopted for numerical simulations using the following assumptions: all transport properties, such as thermal and electrical conductivity or viscosity, are assumed to be constant; the density of solid phase equals the density of liquid phase; the phases are in local thermodynamic equilibrium; the velocity of solid phase in the upper part of the mushy zone is equal to the velocity of the liquid phase. The mushy region is modeled using a mixture viscosity formulation. The Lorentz force in the Navier-Stokes equation has been calculated by means of an analytical solution for the time-averaged Lorentz force for a finite cylinder. The resulting set of eqiuations is discretized by an implicit finite-volume, finite-difference based method, and solved by using the SIMPLE algorithm.
Our results show that the velocity field undergoes distinct modifications during solidification indicating the occurrence of more sophisticated flow patterns as known from the isothermal case.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The motion of single Argon bubbles rising in the eutectic alloy GaInSn under the influence of a DC magnetic field was examined. The magnetic field lines were aligned either in longitudinal or in transverse direction. The magnetic field strength was chosen up to 0.3 T corresponding to magnetic interaction parameters N of 1.5. The experiments were carried out in the following parameter range: 2500 < Re < 5500, 2 < Eo < 7, Mo = 2.4e-13. The liquid metal was in a cylindrical container at rest. The Ultrasound Doppler Velocimetry (UDV) was applied to determine bubble and liquid velocities simultaneously. The measured bubble terminal velocity showed oscillations indicating a zig-zag movement of ellipsoidal bubbles. The measurements revealed a distinct electromagnetic damping of the bubble induced liquid velocity leading to more rectilinear bubble trajectories. Within the present interaction number range (N < 2), the applied magnetic field can either increase or decrease the bubble drag coefficient depending on the bubble size and the magnetic interaction parameter. Moreover, significant modifications of the bubble wake structure were observed. Raising of the magnetic field strength causes an enlargement of the eddy structures in the wake. In case of the longitudinal magnetic field the Strouhal number St decreases with increasing magnetic interaction parameter.]]></dc:description>

<dc:description><![CDATA[We present the transverse momentum spectra and rapidity distributions of \pi^{-} and K^0_S in Ar+KCl reactions at a beam kinetic energy of 1.756 A GeV measured with the spectrometer HADES. The reconstructed K^0_S sample is characterized by good event statistics for a wide range in momentum and rapidity. We compare the experimental \pi^{-} and K^0_S distributions to predictions by the IQMD model. The model calculations show that K^0_S at low tranverse momenta constitute a particularly well suited tool to investigate the kaon in-medium potential. Our K^0_S data suggest a strong repulsive in-medium K^0 potential of about 40 MeV strength.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Multiply twinned FePt nanoparticles with icosahedral structures were prepared by dc magnetron sputtering in argon. The icosahedral structure of these particles is known to be very stable against structural transformations into both the face-centered cubic phase (fcc, A1) and the chemically ordered tetragonal L10 phase upon in-flight or post-deposition thermal annealing. Irradiation of these multiply twinned FePt particles with 5  keV He ions, however, resulted in a transformation into predominantly single crystalline fcc particles at high ion fluences of f>1017  ions/cm2. Adjacent particles were observed to coalesce under the effect of He irradiation, and the size of individual particles was found to be slightly reduced, which indicates a high atomic mobility owing to temporarily enhanced defect concentrations caused by the ion bombardment. Strikingly, there was no indication for the occurrence of L10 ordered FePt nanoparticles upon ion irradiation in these samples.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The crystallization of amorphous silicon films deposited on glass, using the flash lamp annealing process was realized and studied. The duration of the flash is 20 ms, about two orders of magnitude shorter than the standard rapid thermal annealing process. The a-Si films deposited on Coming glass were irradiated with different energy densities and crystallized exhibiting grains with a mean size up to 6 mum. In order to reduce the strain due to the thermal gradient, the samples were preheated from the backside. The ability of the FLA process to eliminate the ingrain defects in already crystallized poly-Si films at 600 degreesC is also demonstrated.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[First lasing of the mid infrared FEL at ELBE was achieved on May 7, 2004. The Radiation Source ELBE at the Forschungszentrum Rossendorf in Dresden is currently under transition from commissioning to regular user operation. Presently the electron linac produces an up to 18 MeV, 1 mA (cw) electron beam which is alotted to generate various kinds of secondary radiation. After the successful commissioning of the bremsstrahlung and channeling-X-ray facilities during 2003 stable lasing has now been observed in the IR range (15 to 22 μm). The oscillator FEL is equipped with two planar undulator units, both consisting of 34 hybrid permanent magnet periods of 27.3 mm (Krms = 0.3 - 0.8). The distance between the two parts is variable and the gaps can be adjusted and tapered independently. At 19.6 µm an optical power of 3W was out-coupled in a macro pulse of 0.6 ms duration using an electron beam energy of 16.1 MeV and an energy spread of less than 100 keV; the micropulse charge was 50 pC and its width slightly above 1ps. With the installation of a second acceleration module for additional 20 MeV smaller wavelengths will become available in the near future.]]></dc:description>

Molekularbiologische Analysen der metallbindenden S-layer wiesen die Existenz von zwei unterschiedlichen S-layer-Genen nach. Sowohl das funktionale Gen als auch das stumme Gen wurde sequenziert.

<dc:description><![CDATA[We present a novel high-yield Thomson scattering geometry that takes advantage of compact electron bunches, as available in advanced, low-emittance linear accelerators or laser wakefield accelerators. In order to avoid the restrictions on the X-ray photon yield imposed by the Rayleigh limit, we use ultrashort, pulse-front tilted laser pulses in a side-scattering geometry. Such a traveling-wave setup allows an overlap of electron and laser beams, even after propagating over distances much longer than the Rayleigh length. Experimental designs are discussed and optimized for different scattering angles. Specifically, to minimize group delay dispersion at large scattering angles > 10° degrees, we propose the use of varied-line spacing (VLS) gratings for spatio-temporal laser pulse shaping. Compared to head-on (180° degrees) Thomson scattering, interaction lengths are in the centimeter to meter range and photon numbers for ultrashort X-ray pulses can increase by several orders of magnitudes.]]></dc:description>

<dc:title><![CDATA[Extension of CFD codes - application to two-phase flow safety problems, phase 2]]></dc:title>
<dc:source><![CDATA[OECD: Report NEA/CSNI/R(2010)2, 2010<br>137 Seiten]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[This document is an extension of the NEA/SEN/SIN/AMA(2006)2 report produced by the Writing Group 3 on the extension of CFD to two-phase flow safety problems, which was formed following the recommendations made at the Exploratory Meeting of Experts to Define an Action Plan on the Application of Computational Fluid Dynamics (CFD) Codes to Nuclear Reactor Safety Problems held in Aix-en-Provence, in May 2002. Extension of CFD codes to two-phase flow is a chance for safety investigations, by giving some access to smaller scale flow processes which were not seen by present tools. Using such tools as part of a safety demonstration may bring a better understanding of physical situations, more confidence in the results, and an estimation of safety margins. The increasing computer performance allows a more extensive use of 3D modelling of two-phase Thermalhydraulics with finer nodalization. However, models are not as mature as in single phase flows and a lot of work has still to be done on the physical modelling and numerical schemes in such two-phase CFD tools. The Writing Group listed and classified the NRS problems where extension of CFD to two-phase flow may bring real benefit and also classified different modelling approaches. First ideas were reported about the specification and analysis of needs in terms of validation and verification.]]></dc:description>

<dc:description><![CDATA[Plant-measured data provided within the specification of the OECD/NEA VVER-1000 coolant transient benchmark (V1000CT) were used to validate the DYN3D/RELAP5 and DYN3D/ATHLET coupled code systems.

<dc:date>2005</dc:date>
<dc:description><![CDATA[Dynamics of the Molten Salt Reactor - one of the 'Generation IV' concepts - was studied in this paper. The graphite-moderated channel type MSR was selected for the numerical simulation of the reactor with liquid fuel. The MSR dynamics is very specific because the fuel flow influences the delayed neutrons distribution. Presently, there are not many accessible numerical codes appropriate for the MSR simulation, therefore the DYN3D-MSR code was developed based on the FZR in-house code DYN3D. It allows calculating of full 3D transient neutronics in combination with parallel channel type thermal-hydraulics. By means of DYN3D-MSR, several transients typical for the liquid fuel system were analyzed. Those transients were initiated by reactivity insertion, by overcooling of fuel at the core inlet, by the fuel pump start-up or coast-down, or by the blockage of selected fuel channels. The results of these transient studies have shown that the dynamic behavior of MSR is acceptable with respect to the reactor safety.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Measurements of the cross sectional distribution of gas fraction and bubble size distributions were conducted in a vertical pipe with an inner diameter of 51.2 mm and a length of about 3 m for air/water bubbly and slug flow. The use of a wire-mesh sensor allows a high resolution of the gas fraction data in space as well as in time. From these data time averaged values for the two-dimensional gas fraction profiles decomposed according to a large number of bubble size classes were calculated. This allows to extract data for the radial gas fraction profiles for a given range of bubble sizes as well as data for local bubble size distributions. The structure of the flow is characterized by these data. The measurements were done for up to 10 different inlet lengths and for about 100 combinations of gas and liquid volume flow rates. The data are very useful for the development and validation of meso-scale models for the forces acting on a bubble in a shear field of the liquid flow and models for bubble coalescence and break-up. Such models are necessary for the qualification of CFD codes for the simulation of bubbly flows.]]></dc:description>

<dc:description><![CDATA[We report on the generation of proton pulses with maximum energies exceeding 15MeV bymeans of the irradiation of few micron thick metal foils by ultrashort (30 fs) laser pulses at a power level of 100 TW. In contrast to the well known situation for longer laser pulses, here, a near linear scaling of the maximum proton energy with laser power can be found. Aiming for radiobiological applications the long and short term stability of the laser plasma accelerator as well as a compact energy selection and dosimetry system is presented. The first irradiation of in vitro tumour cells showing dose dependent biological damage is demonstrated paving the way for systematic radiobiological studies.]]></dc:description>

<dc:description><![CDATA[In processes involving electrically conducting liquids, the application of an external magnetic field offers efficient opportunities for a contactless flow control and fluid handling. However, for a well-aimed optimisation of the flow structure local information about flow quantities like velocity, pressure, temperature, concentration or void fraction are necessary. In case of liquid metals the choice of a suitable measuring technique is a crucial problem, because the user is confronted not only with the opaqueness but also with high temperatures as well as a strong chemical reactivity of the fluid against many materials. Therefore, measuring techniques well-known from ordinary hydrodynamics generally fail for liquid metal applications. As a consequence, no commercial measuring systems are available for liquid metal applications. 
During the last years experimental activities of FZR were focussed on the development and qualification of techniques to measure the velocity in liquid metal flows. Various liquid metal model experiments with various liquid melts at different temperatures have been performed to test and evaluate local sensors as well as integral methods.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[<p>A new facility for experiments in pulsed high magnetic fields (HLD*) is under construction at the Forschungszentrum Rossendorf (FZR) in Dresden, Germany. In order to offer a wide spectrum of experimental capabilities at HLD, pulsed field coils are planned in the parameter range 60 T, 50 mm, 1s to 100 T, 20 mm, 0.01 s for maximum field, bore, and pulse duration. These magnets will be energized by a modular 50 MJ / 24 kV / 600 kA capacitor bank. The pulsed magnets will be complemented by commercial superconducting magnets for dc fields up to 20 T. Besides many other experimental capabilities, as a unique opportunity, infrared spectroscopy in the wavelength range between 5 and 150 µm will be possible in pulsed fields by connecting the pulsed field lab with the new free-electron-lasers of the neighbouring superconducting electron linear accelerator ELBE of the FZR. <br>
Since 1999, we have gained experience in a pilot project by building a 1.0 MJ / 10 kV / 61 T high field laboratory. Funded since 2003, we have already completed our laboratory building and machineshop. In addition, we have planned and started to assemble the 50 MJ power supply which can be partly used in 2005 and will be fully operational by 2006. First pulsed test coils have already been built and tested using a 1.44 MJ / 24 kV / 37 kA pilot power supply manufactured at FZR. Currently we are starting to order our experimental equipment. Together with the user coils, this equipment will be mainly installed and put into operation during 2006. We are planning to open the doors of our laboratory to users in 2007.</p>
 
<p>* The HLD project has been jointly submitted for funding by the Forschungszentrum Rossendorf FZR, the Leibniz Institute for Solid State and Materials Research Dresden, the Max Planck Institute for Chemical Physics of Solids, the Max Planck Institute for the Physics of Complex Systems, and the Institute for Solid State Physics of the Dresden Technical University in 1998. It is jointly funded for installation by the Federal Ministry of Education and Research of Germany and the Saxon Ministry of Science and the Fine Arts.</p>]]></dc:description>

<dc:source><![CDATA[Internationaler ILK-Workshop, 23.02.2005, Frankfurt/Main, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Die Internationale Länderkommission Kerntechnik (ILK) hat 2004 eine Stellungnahme zur Bewertung der Nachhaltigkeit der Kernenergie und anderer Technologien zur Stromerzeugung vorgelegt.
Die Bewertung beruht u.a. auf der Quantifizierung von Indikatoren, wie etwa die Produktionskosten oder die CO-2-Emission, die verschiedene Nachhaltigkeitsaspekte charakterisieren und der Aggregation dieser Indikatoren zu einem einzigen Nachhaltigkeitskennwert für jede der betrachteten Energieoptionen.
Die Aggregation kann beispielsweise über den Totalkostenansatz oder mit Hilfe der Multikriteriellen Entscheidungsanalyse (MCDA) erfolgen. Die beiden Verfahren führen in der Regel zu unterschiedlicher Nachhaltigkeitsbewertung. Dies liegt zum einen daran, dass einige der Indikatoren finanziell nicht fassbar sind und deshalb im Totalkostenansatz nicht berücksichtigt werden. Zum anderen sind bei der Aggregation mit Hilfe der MCDA Wichtungsfaktoren für Einzelindikatoren und die "Nachhaltigkeitssäulen" Wirtschaft, Umwelt, Gesellschaft festzulegen. Bislang stehen keine Leitlinien für die Fixierung dieser  Gewichtungen zur Vefügung. Der Vortrag stellt die genannten Aggregationsverfahren vor und diskuiterit dann Vor- und Nachteile.]]></dc:description>

<dc:description><![CDATA[We have measured the ac susceptibility and resistivity of highly pure samples of the intermetallic compound LaCu<sub>6</sub> down to ultralow temperatures. We have prepared the samples by arc melting of stoichiometric amounts of 99.99\% La and 99.9999\% Cu in a water-cooled copper crucible under Ar protective atmosphere and analysed them by x-ray diffraction and SQUID magnetometry. At T≤T<sub>c</sub> = 0.16 K we observe a superconducting transition. Due to the manifold physical properties of isostructural ReCu<sub>6</sub> compounds (e.g. RE = Ce: heavy fermion system, RE = Pr: hyperfine enhanced nuclear spin system, RE = Nd: electronic antiferromagnet), numerous studies of interplay phenomena may become possible in the quasibinary compounds RE<sub>1-x</sub>La<sub>x</sub>Cu<sub>6</sub>, respectively.]]></dc:description>

<dc:description><![CDATA[Compared to magnetically doped superconductors described by the theory of Abrikosov and Gorkov, electronic singlet ground state systems can have a much larger critical concentration of magnetic impurities, following the model of Keller and Fulde. The recent study of the superconducting Van Vleck paramagnet La<sub>{1-x}</sub>Pr<sub>x</sub>Te revealed a critical Pr<sup>{3+}</sup> concentration x close above 0.50. Surprisingly, in La<sub>{0.50}</sub>Pr<sub>{0.50}</sub>Te the superconducting state with T<sub>c</sub> = 0.20 K appeares not to be stable down to zero temperature. Instead, a reentrant transition to the normal state likely caused by the hyperfine enhanced magnetic moments of the <sup>{141}</sup>Pr nuclei occurs at about 0.02 K. Although these moments are not in a magnetically ordered ground state at T = 0.02 K, their contribution to Cooper pair breaking seems to be even stronger than of ferromagnetically ordered but non enhanced nuclear moments in type-I superconducting AuIn<sub>2</sub>.]]></dc:description>

<dc:description><![CDATA[The behavior of particles driven through a narrow constriction is investigated in experiment and simulation. The system of particles adapts to the conﬁning potentials and the interaction energies by a self-consistent arrangement of the particles. It results in the formation of layers throughout the channel and of a density gradient along the channel. The particles accommodate to the density gradient by reducing the number of  layers one by one when it is energetically favorable. The position of the layer reduction zone ﬂuctuates with time while the particles continuously pass this zone. The ﬂow behavior of the particles is studied in detail. The velocities of the particles and their diffusion behavior reﬂect the inﬂuence of the self-organized order of the system.]]></dc:description>

<dc:source><![CDATA[Workshop "Ionenstrahlphysik und -technologie", 11.-12.04.2005, Leipzig, Deutschland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[As an example, we report on the tailoring of the magnetic properties of Permalloy (20 nm Ni81Fe19) by means of 30 keV Cr implantation. Due to the doping the Curie temperature of the Permalloy film decreases with the implantation fluence and drops below room temperature at an averaged Cr concentration of about 7 at-%. Also the saturation magnetization and the uniaxial anisotropy decrease. However the magnetic damping behavior of Cr implanted Permalloy films is strongly enhanced which is due to a combination of structural changes and alloying effects in the thin film. In order to clarify the basic mechanism for the enhancement the chemical and structural contributions to the magnetic damping parameter are separated by a comparison to results of 30 keV Ni implantation.]]></dc:description>

<dc:description><![CDATA[Many references from the cast metal literature are known discussing the effect of melt convection during the early stages of solidification on the grain structure. The application of mechanical or electromagnetic stirring, ultrasonic or sonic vibrations promotes the formation of fine, equiaxed grains. In this paper experimental and numerical investigations will be presented concerning the influence of a flow driven by a rotating magnetic field (RMF) on the momentum, heat and mass transfer within binary Sn-Pb alloys solidified directionally. The ultrasound Doppler velocimetry (UDV) was applied to measure the bulk flow during solidification. 
The continuum formulation based model has been adopted for numerical simulations. The mushy region is modeled using a mixture viscosity formulation. The Lorentz force in the Navier-Stokes equation has been calculated by means of an analytical solution given by for a finite cylinder. 
Our results show that the velocity field undergoes distinct modifications during solidification indicating the occurrence of more sophisticated flow patterns as known from the isothermal case. The forced convection causes distinct modifications of the temperature and concentration field such as a reduction of the temperature gradient ahead of the solidification front and a shift of the mixture concentration towards the eutectic concentration on the axis of the ingots. Without electromagnetic stirring the alloy solidifies solely in form of dendrites aligned parallel to the heat flow direction. In contrast, a transition from a columnar to an equiaxed growth (CET) is observed if the solidifying ingot is exposed to an RMF.

<dc:source><![CDATA[Materials Science and Engineering A 402(2005), 55-65]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[An experimental study with respect to the influence of a rotating magnetic field (RMF) on the unidirectional solidification of Pb-Sn alloys is reported. The magnitude of the bulk flow in the melt generated by the RMF varies with the magnetic Taylor number Ta. The forced convection causes distinct modifications of the temperature and concentration field such as a reduction of the temperature gradient ahead of the solidification front. Without electromagnetic stirring the alloy solidifies solely in form of dendrites aligned parallel to the heat flow direction. In contrast, a transition from a columnar to an equiaxed growth (CET) is observed if the solidifying ingot is exposed to an RMF. The position of the CET is shifted towards the bottom of the casting by increasing the Ta number. The CET was found to occur for a cooling rate of about 0.4 K/s and temperature gradients in the range between 0.6 and 1.0 K/mm]]></dc:description>

<dc:description><![CDATA[The magnetorotational instability (MRI) triggers turbulence and enables outward transport of angular momentum in hydrodynamically stable rotating shear flows, e.g., in accretion discs. What laws of differential rotation are susceptible to the destabilization by the axial or helical magnetic field? The answer to this vital for astrophysical and experimental applications question inevitably leads to the study of spectral and geometrical singularities on the instability threshold of the operator of this problem. The singularities provide a connection between seemingly discontinuous stability criteria and thus explain several paradoxes in the theory of MRI that were kept poorly understood since 1950s.]]></dc:description>

<dc:description><![CDATA[At the Forschungszentrum Dresden-Rossendorf a new neutron time-of-flight facility has been set up. Fast neutrons in the energy range from 0.1 MeV to 10 MeV are produced using pulsed electron beams from a superconducting electron linear accelerator. Short beam pulses of less than 10 ps allow high-resolution time-of-flight experiments with the aim to determine interaction cross sections of neutrons with reactor structural materials and actinides at energies matching the neutron energies in fast reactors. Following experiments using a thermionic electron injector a new superconducting radio-frequency injector has been built which will allow average beam currents of 0.5 mA at a repetition rate of 500 kHz.
Meanwhile, first experiments on inelastic neutron scattering cross sections on 56Fe and total neutron cross sections on aluminium and tantalum have been performed as benchmark experiments. While photons from the de-exciting transitions are being detected using a 16-element BaF2 scintillator array, neutrons are measured with five low-threshold plastic scintillation detectors.

<dc:description><![CDATA[In the course of our investigation of the heavy fermion compound CeCu<sub>6</sub>,
we have recently performed measurements of the heat capacity as well as elastic neutron diffraction down to ultralow temperatures. In the last decade, various groups have investigated this compound by means of susceptibility, magnetization, nuclear quadrupole resonance, and thermal expansion as well. There is a strong evidence for a magnetic ordering transition at about 2.5 mK. Here we like to present our latest heat capacity data taken at 0.1 mK ≤ T ≤ 100 K as well as neutron diffraction data taken down to 15 mK. These results give further
hints for magnetic correlation effects in CeCu<sub>6</sub>.]]></dc:description>

<dc:source><![CDATA[International Conference on Ultralow Temperature Physics, 28.-31.08.2002, Kanazawa, Japan]]></dc:source>
<dc:date>2002</dc:date>
<dc:description><![CDATA[Since the first experimental finding of a competition between nuclear magnetism and superconductivity in the nuclear ferromagnet AuIn2, investigations have been extended to Al, Sn, Rh, In, AuAl<sub>2</sub>, and very recently to Pr<sub>1-x</sub>La<sub>x</sub>Te. The experiments have demonstrated that the contribution of nuclear magnetism to Cooper pair breaking is a common phenomenon. Even in a system with tiny nuclear magnetic moments (e.g. Sn), a reduction of the critical field B<sub>c</sub>(T) has been detected at ultralow temperatures. In more detail, the observed influences of nuclear magnetism on superconductivity vary strongly with the size of hyperfine coupling, ranging between a tiny reduction of B<sub>c</sub>(T) in the case of weak hyperfine coupling (AuAl<sub>2</sub>) and the complete destruction of superconductivity in the opposite case of strongly coupled and hyperfine enhanced nuclear spin systems (e.g. Pr<sub>0.50</sub>La<sub>0.50</sub>Te). The hyperfine interaction appeares to be the dominant mechanism for the nuclear magnetic contribution to Cooper pair breaking.]]></dc:description>

<dc:source><![CDATA[RHMF, 20.-23.07.2003, Toulouse, Frankreich]]></dc:source>
<dc:date>2003</dc:date>
<dc:description><![CDATA[We are building a user facility for experiments in pulsed high magnetic fields at the Forschungszentrum Rossendorf, Dresden. Based on the experience obtained since 1999 from a pilot pulsed field laboratory with a 1 MJ / 10 kV capacitor bank and magnets for the field range up to 60 T at the IFW, the new large scale facility will be built until 2006. It will comprise a new laboratory building, a 50 MJ / 24 kV capacitor bank, and high performance experimental equipment including various pulsed magnets for the field range up to 100 T / 10 ms. In order to offer a wide spectrum of experimental possibilities, the pulsed field magnets are planned with various bore diameters (up to 50 mm) and various pulse times (10 ms to 1 s). As a unique opportunity, infrared spectroscopy in the wavelength range between 5 and 150 µm will be possible at high magnetic fields by connecting the pulsed field lab to the free-electron-lasers of the superconducting electron linear accelerator ELBE of the FZR. The german Wissenschaftsrat has recently recommended the Dresden High Field Project without any hesitation. The project is a joint effort of the FZR, the IFW, the Max-Planck-Institut für chemische Physik fester Stoffe, the Max-Planck-Institut für Physik komplexer Systeme, and the Institut für Angewandte Physik of the TU Dresden.]]></dc:description>

<dc:description><![CDATA[<p>In nature, the magnetic field acts as a fundamental thermodynamic property like temperature or pressure. For this, the magnetic field plays a decisive role in many facets of nature, and in consequence, is of importance in several natural sciences. In particular, the understanding of magnetic properties of matter and the interplay of magnetism with other quantities is a challenging field of research. Under extreme conditions, like low temperatures, high pressures, and high magnetic fields, new interesting properties of matter can appear and the understanding of materials properties can crucially be gained.</p>
 
<p>Further, the manifold magnetic effects in nature and in particular the magnetic properties of matter are a rich source for technological innovations. Historically, there is an immense number of inventions like the compass, electro motor, generator, relay, magnetic brake, levitating train, nuclear magnetic resonance tomograph, hard disk drive, magneto-electric random access memory. Nowadays, in transport, energy production, medicine, communication, data storage, and other areas of daily live, magnetic systems, components, and properties are used in a large variety.</p>
 
<p>In the last decades, the application of high magnetic fields became a powerful research tool. Especially in solid state physics important discoveries like the integer quantum Hall and fractional quantum Hall effect, both honoured with the Physics Nobel Prize, are based on experiments in very high magnetic fields.</p>
 
<p>In order to establish a large modern user facility with unique experimental possibilities for science in high magnetic fields and in order to provide an easy access for the high field community in Europe, the Dresden High Field Project has been created. Since 2003 this facility is under construction. In this paper, we give a snapshot on the status and some recent achievements in the course of the project. The Dresden High Field Laboratory for nondestructive pulsed magnetic fields up to 100 T will open its doors as a user facility in January 2007.  </p>]]></dc:description>

<dc:description><![CDATA[Systematic Slow Positron Implantation Spectroscopy (SPIS) and Atomic Force Microscopy (AFM) studies of various 6H-SiC samples are presented to clear the role of conductivity type, crystal quality, ion implantation (B+, Al+, N+), and annealing (1.650 °C) on the formation of continuous long furrows (undulations) running in one direction across the wafer surface. It is found that the observed changes in surface morphology are primary the result of thermal activation and thus occur independent of conductivity type, crystal quality, and type of ion implantation. In terraces in-between the long furrows, stripe like islands with a discrete height in the nanometer range have been observed which may have some link with the ion implantation chosen. SPIS results clearly indicate the formation of vacancy clusters in n-type material which are connected with the mobility of nitrogen in the samples at elevated temperatures. It is found that defect profiling by SPIS is not influenced by the changes in surface morphology observed due to annealing.]]></dc:description>

<dc:description><![CDATA[Uranium ores are very common in several regions of Germany, e.g. Saxony, Thuringia and Bavaria. Weathering and ore mining are processes which result in mobilization of uranium. So far only a general radiation dose limit for drinking water exists in Germany but no limit value for uranium itself. The latter is  a radioactive and also toxic element and therefore discussions have raised to adopt a limit value for uranium in Germany. Against this background the development of novel strategies for cleaning uranium contaminated water became an increasingly interesting subject. In the past the Bacillus sphaericus strain JG-A12, recovered from the uranium mining waste pile Haberland nearby the town of Johanngeorgenstadt, was demonstrated to bind selectively several heavy metals including uranium [1]. Molecular and structural analyses of the uranium complexes formed by the cells, spores and the surface layer (S-layer) protein of B. sphaericus JG-A12 via extended X-ray absorption fine structure (EXAFS) spectroscopy identified carboxyl and phosphate groups as binding sites for uranium [2]. Moreover sol-gel techniques were used for immobilization of B. sphaericus JG-A12 cells in a porous silicate matrix. [4, 5]. The obtained biological ceramic (biocer) is particularly suitable for the use as selective filter material for the immobilization of uranium from polluted industrial waters.

This work is aimed to investigate the capability of biocers containing B. sphaericus JG-A12 cells to remove uranium from contaminated drinking water. For the experiments four different tap water samples supplemented with 30 µg uranium per liter and one Hungarian mineral water with a uranium content of 142 µg uranium per liter were selected. Uranium sorption by the biocer showed the removal of over 99% of dissolved uranium from the tap water samples. In the case of the heavy metal containing and highly saline mineral water 86% of uranium and 76% of zinc were immobilized.

In order to improve the uranium binding capacity of the biocers, the uranium sorption by B. sphaericus JG-A12 cells was tested depending on the amount of phosphorus present in the growth medium. Highest binding capacities were achieved with biomass grown in phosphate rich media, containing at least 1.4 mM phosphorus. In contrast, the binding capacity was remarkably lower with biomass grown in phosphate limited medium. Furthermore uranium binding of the isolated and purified S-layer of B. sphaericus JG-A12 was investigated. Interestingly, the S-layer of B. sphaericus JG-A12 possesses even at low concentration of uranium higher affinity to uranium than the S-layer protein of its closest relative B. sphaericus NCTC 9602 or the reference protein bovine serum albumine. Recent analyses of the S-layer genes of B. sphaericus JG-A12 [6] allow to perform in future genetic modifications of the cell surface of B. sphaericus JG-A12. This displays a further possibility to enhance the capacity and the selectivity of the uranium binding by the next generation of biocers.

<dc:description><![CDATA[The objective of the ECORA project is the evaluation of computational fluid dynamics (CFD) software for reactor safety applications, resulting in best practice guidelines (BPG) for an efficient use of CFD for reactor safety problems. The project schedule is as follows: (i) establishment of BPGs for use of CFD codes, for judgement of CFD calculations and for assessment of experimental data; (ii) assessment of CFD simulations for three-dimensional flows in LWR primary systems and containments; (iii) quality-controlled CFD simulations for selected UPTF and SETH PANDA test cases; and (iv) demonstration of CFD code customisation for PTS analysis by implementation and validation of improved turbulence and two-phase flow models. The project started in October 2001 and is for a period of 36 months. The project consortium consists of 12 partners combining thermal-hydraulic experts, code developers, safety experts and engineers from nuclear industry and research organizations. At mid-term, the following results were achieved: (i) BPGs are available for simulations of reactor safety relevant flows. These BPGs have found interest in the European projects FLOMIX-R, ASTAR and ITEM; (ii) important flow phenomena for PTS and containment flows have been identified; (iii) experimental data featuring these phenomena have been selected and described in a standardised manner suitable for simulation with CFD methods; (iii) surveys of existing CFD calculations and experimental data for containment and primary loop flows have been performed and documented; (iv) first results for simulations of PTS-relevant single-phase and two-phase flow cases are available.
Documentation is available via the internet at http://domino.grs.de/ecora/ecora.nsf. The models developed within the project are implemented in industrial and commercial CFD software packages and are therefore accessible by industry and research institutions.]]></dc:description>

<dc:source><![CDATA[Journal of Mathematical Physics 46(2005), 063504]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[It is shown that the α²-dynamo of Magnetohydrodynamics, the hydrodynamic Squire equation as well as an interpolation model of PT-symmetric Quantum Mechanics are closely related as spectral problems in Krein spaces. For the α²-dynamo and the PT-symmetric model the strong similarities are demonstrated with the help of a 2×2 operator matrix representation, whereas the Squire equation is re-interpreted as a rescaled and Wick-rotated PT-symmetric problem. Based on recent results on the Squire equation the spectrum of the PT-symmetric interpolation model is analyzed in detail and the Herbst limit is described as spectral singularity.]]></dc:description>

<dc:description><![CDATA[Die Nutzung biologischer Strukturen für die Nanotechnologie ist auf Grund der Größe vieler wichtiger Biomoleküle ein naheliegender Ansatz. S-Layer (engl.: surface layer) sind als äußerste parakristalline Proteinschicht bei vielen Bakterien und Archaea zu finden. Die Untereinheiten dieser Schichten, Protein- oder Glykoproteinmonomere, haben die Fähigkeit zur Selbstorganisation als monomolekulare gitterartige Schicht und eignen sich deshalb bestens zur Funktionalisierung von Oberflächen und zur Herstellung von Ultrafiltrationsmembranen. Einige S-Layer von bakteriellen Isolaten aus Schwermetall- und Radionuklid-belasteten Umgebungen haben außerdem die Eigenschaft, bestimmte Metalle zu binden und können deshalb zur Herstellung von Nanostrukturen, Metallclustern definierter Größe oder als selektive Bindungsmatrix in Filter zur Reinigung kontaminierter Wässer eingesetzt werden.]]></dc:description>

<dc:description><![CDATA[The common concept of heavy metal migration in the hydrosphere differentiates between solid and liquid phase, considered as immobile and mobile. Colloidal phases are often neglected, which may have the following consequences on environmental hazard prognosis (Zänker et al. 2003):
a) The contaminant is regarded as mobile in the model, but it adsorbs on colloids which aggregate and settle (natural attenuation): the prognosis is too pessimistic.
b) The contaminant is regarded as immobile in the model due to adsorption on the host rock, but in part it adsorbs on colloids which are transported: the prognosis is too optimistic.
c) Only if the contaminant is fully mobile, i.e. it is not adsorbed onto solid phases: colloidal transport is irrelevant and the model description is correct.
This study is focused on the incidence of colloids and their binding of toxic metals in streams of the Erzgebirge (Germany), a low mountain region which strongly suffered in the past from mining activities, e.g. uranium mining, and from acid rain loads exceeding the buffering reaction by weathering. Mildly acidic conditions (pH 5-6.5), which may occur in the runoff from dumps or arise on the reversal from stronger acidification (Ulrich and Meybohm 2005), or by mixing of waters with different loads of protons and metals, favor the generation of colloids by hydrolysis of iron (Fe) and aluminum (Al) or by dissolution of clay minerals and precipitation of secondary ferric oxides. 
Based on samples from the confluence of two forest streams in the Erzgebirge, 27Al MAS NMR spectroscopy showed that Al-rich colloids contain distinct Al(O)4 centers similar to the -Keggin polyoxocation AlO4Al12(OH)24(H2O)127+(aq) [Al13] (left Fig.). These colloids form via aggregation of the Al13 nanoclusters (Furrer et al. 2002) and bear a high surface density of functional groups capable of accumulating heavy metal cations.
Fe-rich colloids (right Fig.), which often consist of metastable ferrihydrite, exhibit similar properties. Such colloids form when acidic seepage (e.g. from a uranium mine or dump) mixes with near-neutral surface water. Uranium (U), which is soluble under strongly acidic (UO22+) and alkaline (uranyl carbo-nate complexes) conditions, will be scavenged and immobilized by colloids which aggregate and settle in the slightly acidic pH region. On the other hand, contaminants that are usually immobile (As, Cu, Pb), can be mobilized by colloids. The molecular structure of some sorption complexes derived from EXAFS and ATR FT-IR spectroscopy is discussed.

<dc:source><![CDATA[12th International Conference on Particle Induced X-Ray Emission and its Analytical Applications, 27.06.-02.07.2010, Guildford, UK]]></dc:source>

<dc:description><![CDATA[This 18th century object with delicate on-glaze decorations let arise doubts regarding its complete originality. Comparing both base body and cover, the shades of porcelain glazing differ visually. Moreover, the painting shows slight differences in color and flow. Simultaneous PIXE and RBS (Rutherford Backscattering Spectrometry) using the 4-MeV proton beam in air [1] proved ideal to get convincing answers. The maximum proton beam intensity was only 200 pA for 30 s acquisition time in order to ensure non-destructive analysis of the very sensitive material.
For the green colorant of leaves of trees, painted on both bottom and cover, the artist used copper green pigment [2]. For painting the bottom of the base body Cu was the starting material; brass was certainly applied for the cover as deduced from additional Zn lines displayed by PIXE. In the latter case the green pigment was obviously brightened by the addition of Co. Pink decoration of the cover could be identified as made from purple due to small Au-L lines. They were not visible analysing the pink skirt, painted on the bottom, because of superimposed intense Pb-L lines originating from the glazing. Comparatively, the X-ray spectrum obtained from pure glazing of the cover shows much lower Pb-L intensity. RBS was helpful for getting information on the depth distributions of Pb regarding the different types of glazing. This is illustrated in the graphs below. Whereas the bottom of the porcelain box comprises thick and lead containing glazing, the RBS spectrum taken from glazing of the cover makes clear that only little Pb exists, which is localized at the glazing surface. This can be attributed to a surface polishing process carried out in the past.

<dc:description><![CDATA[This 18th century object with delicate on-glaze decorations let arise doubts regarding its complete originality. Comparing both base body and cover, the shades of porcelain glazing differ visually. Moreover, the painting shows slight differences in color and flow. Simultaneous PIXE and RBS (Rutherford Backscattering Spectrometry) using the 4-MeV proton beam in air [1] proved ideal to get convincing answers. The maximum proton beam intensity was only 200 pA for 30 s acquisition time in order to ensure non-destructive analysis of the very sensitive material.
For the green colorant of leaves of trees, painted on both bottom and cover, the artist used copper green pigment [2]. For painting the bottom of the base body Cu was the starting material; brass was certainly applied for the cover as deduced from additional Zn lines displayed by PIXE. In the latter case the green pigment was obviously brightened by the addition of Co. Pink decoration of the cover could be identified as made from purple due to small Au-L lines. They were not visible analysing the pink skirt, painted on the bottom, because of superimposed intense Pb-L lines originating from the glazing. Comparatively, the X-ray spectrum obtained from pure glazing of the cover shows much lower Pb-L intensity. RBS was helpful for getting information on the depth distributions of Pb regarding the different types of glazing. This is illustrated in the graphs below. Whereas the bottom of the porcelain box comprises thick and lead containing glazing, the RBS spectrum taken from glazing of the cover makes clear that only little Pb exists, which is localized at the glazing surface. This can be attributed to a surface polishing process carried out in the past.

<dc:title><![CDATA[Experimental observations related to the lateral lift force in poly-dispersed bubbly flows]]></dc:title>
<dc:source><![CDATA[48th European Two Phase Flow Group Meeting, 27.-30.06.2010, London, United Kingdom]]></dc:source>

<dc:description><![CDATA[The influence of the lateral lift force on trajectories of single bubbles under idealized conditions was investigated in the past by means of Direct Numerical Simulations (DNS) and by well defined experiments. However, contradictory discussions can be found in literature on the meaning of this force for poly-dispersed flows, i.e. flow with medium or high gas volume fraction. Usually such flows are turbulent and bubble-bubble interaction, i.e. bubble coalescence and breakup play an important role. For this reason it is not self-evident, that the correlation for the lift force coefficient obtained by Tomiyama can be applied for such flows. 
The separation of small and large bubbles in poly-dispersed flows was clearly shown in experiments on vertical pipe flow basing on wire-mesh sensor measurements which allow the measurement of bubble size distributions. The critical diameter at which the lift force changes its sign predicted by the Tomiyama correlations (5.8 mm for air-water flow at ambient conditions) seems to fit in general well with the transition between wall and core peaks in the radial gas volume fraction profiles decomposed according to the bubble size. This was also confirmed for steam-water flows at a pressure of 6.5 MPa for which the critical diameter is at about 3.5 mm according to the correlation. 
However in case of void fraction larger than about 5 % the effect of the lift force is superposed by dynamic effects as bubble coalescence and breakup and radial migration of the bubbles. For this reason it is not possible to conclude on the critical diameter directly from the shape of the radial gas volume fraction profiles. Also, it was argued, that the wall peak of small bubbles can be caused by large bubbles moving fast upwards in the pipe centre and pushing the small bubbles towards the wall. For this reason in the presented work the distribution of bubbles in dependence on radial position and on bubble sizes is investigated in detail for developing flows. New, high-quality data on air-water as well as on steam-water flows in a DN200 pipe are used for these investigations. The validity of the Tomiyama correlation can be confirmed for a wide range of flow rates. Finally the consequences of the lateral lift force on the flow bubble columns, on the stability of homogeneous bubbly flows and on bubble plumes produced by bubble entrainment from impinging jets are discussed.]]></dc:description>

<dc:description><![CDATA[In order to design and optimize pulsed field coils, their current leads, and in particular their reinforcement, we currently test commercial Finite Element software of various suppliers. We concentrate on these programs which have implemented so called "multiphysics modules" which are able to solve combined problems as they typically occur in high field techniques: e.g. calculation of the magnetic field from a current distribution along with the resulting Lorentz forces, stresses, dislocations etc.. In detail, we focus on the programs ANSYS, ANSOFT, as well as FEMLAB. We like to give a brief survey of their usefulness, perspectives, and last but not least, of their cost.]]></dc:description>

<dc:description><![CDATA[In the present study cubic 3C(Si1xC1y)Gex+y solid solutions were created by using ion beam synthesis. 3CSiC thin layers grown on on-axis Si (111) substrates by Molecular Beam Epitaxy were implanted with Ge in order to incorporate Ge atoms in the Silicon Carbide lattice. Two series of experiments were carried out. The implantation energy was chosen to be 140 keV and 200 keV and the implantation dose 1 × 1017 cm2 and 4.7 × 1016 cm2 respectively. The samples were annealed under rapid thermal annealing conditions in the temperature range between 800 °C and 1300 °C. X-ray diffraction measurements indicate an enlargement of the lattice constant. The observed higher absorption in the implanted layers could be a sign of a band gap reduction as a consequence of Ge incorporation.]]></dc:description>

<dc:description><![CDATA[The DYN3D code allowing to calculate the whole reactor core of light water reactors and its transient behaviour has been developed at the Forschungszentrum Rossendorf (FZR). It treats the three-dimensional (3d) neutron kinetics with a two-group diffusion approximation using the nodal method for assemblies with quadratic and hexagonal geometry. As input data DYN3D needs two-group cross sections for the neutrons, which are averaged over each node. These cross sections are generated using the 2d-code-system HELIOS. The necessity to calculate these two-group cross sections three-dimensionally was evaluated with the Monte-Carlo code MCNP and the 2d- and 3d-cell-code TransRay, which has been specially developed for that purpose at FZR. TransRay uses the same solution method as employed by HELIOS. The following reactor cells were investigated: A partially inserted control rod and void (or moderator with a lower density respectively) around a fuel rod as a model for a steam bubble in the moderator region. In general it could be concluded, that a three-dimensional data generation of averaged two-group cross sections is rather necessary for reactor cells with steam bubbles than for reactor cells with absorbers.]]></dc:description>

<dc:description><![CDATA[The DYN3D code allowing to calculate the whole reactor core of light water reactors and its transient behaviour has been developed at the Forschungszentrum Rossendorf (FZR). It treats the three-dimensional (3d) neutron kinetics with a two-group diffusion approximation using the nodal method for assemblies with quadratic and hexagonal geometry. As input data DYN3D needs two-group cross sections for the neutrons, which are averaged over each node. These cross sections are generated using the 2d-code-system HELIOS. The necessity to calculate these two-group cross sections three-dimensionally was evaluated with the Monte-Carlo code MCNP and the 2d- and 3d-cell-code TransRay, which has been specially developed for that purpose at FZR. TransRay uses the same solution method as employed by HELIOS. The following reactor cells were investigated: A partially inserted control rod and void (or moderator with a lower density respectively) around a fuel rod as a model for a steam bubble in the moderator region. In general it could be concluded, that a three-dimensional data generation of averaged two-group cross sections is rather necessary for reactor cells with steam bubbles than for reactor cells with absorbers.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The effect of magnetic fields on momentum and mass transfer in electrochemical processes has been studied by means of Digital Particle Image Velocimetry (DPIV), shadowgraphy and mean current density measurements.

Chronoamperometric copper electrolysis was carried out in a small electrolytic cell (29x46x6 mm) made mainly from PMMA. The sidewalls forming the vertical electrodes consist of thin copper plates behind which permanent magnets could be fixed. The Lorentz force generated from the faradaic currents and the permanent magnets field has been always parallel to the electrodes. Depending on the orientation of the magnets, downwards or upwards directed Lorentz forces could be generated.

The moderate magnetic field of permanent magnets placed behind the electrodes, although its action is limited to the vicinity of the electrodes, is able to promote convection in the whole cell. Flow structures measured by DPIV compare very well with the patterns of the concentration field given by shadography. Steady state limiting current densities as well as initially instationary current density values can be explained by the corresponding velocity measurements. It will be shown that the interplay of Lorentz and buoyancy forces is substantial for the resulting flow structure.]]></dc:description>

<dc:description><![CDATA[The uranyl tricarbonato complex is one of the most important uranyl species under environmental conditions. The tendency to form stable metal-uranyl tricarbonato complexes was found particularly for the interaction with alkaline earth elements. However, under comparable chemical conditions the formation of these complexes is very different. While magnesium tends mainly to the formation of a MgUO2(CO3)32+ - complex, in the case of calcium the Ca2UO2(CO3)3(aq.) complex is the most stable  and the formation of the CaUO2(CO3)32+ - complex is very limited. In the corresponding systems with strontium as well as for barium only the MeUO2(CO3)32+ - complex is formed. The stability constants of the MeUO2(CO3)32+ - complexes increase in the series Mg, Ca , Sr and Ba. The formation of Me2UO2(CO3)3  complexes for Mg, Sr and Ba occurs only in a small concentration range and the formed complexes tends to precipitate. The Me2UO2(CO3)3  complexes for Mg and Ca form stable minerals as bayleyite and liebigite. However several other mineral modifications as zellerite, fontanite, sharpite and rabbittite underline the geochemical importance of this class of compounds.
Analogous phenomena can be expected in the alkaline earth uranyl phosphate systems and first results will be presented.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Driven by the requirement of high cutting efficiency and improvement of wafer flatness wire sawing of GaAs single crystals under brittle material removal conditions has been studied. Crack nucleation and crack propagation were investigated by indentation and scratching tests on polished {100}-oriented semi-insulating GaAs wafers. Based on these results a concept has been developed to control the force balance in the cutting slits so that the deflection of the wires perpendicular to the cutting planes is minimal resulting in cuts of high flatness. The concept has been successfully introduced in mass production of GaAs wafers.]]></dc:description>

<dc:description><![CDATA[The magnetic anisotropy in amorphous soft magnetic FeCoSiB films is modified by He-ion irradiation. A realignment of uniaxial anisotropy depending on the applied field direction in the irradiated areas is observed by magnetometry and complementary domain observation by Kerr microscopy. Using irradiation together with photolithography the films were treated locally, resulting in anisotropy patterned structures. Complicated periodic domain patterns form due to the confined anisotropy distribution. Overall magnetic properties and domain patterns can be adjusted.]]></dc:description>

<dc:description><![CDATA[Different reconstruction techniques are used to reconstruct the distribution of the physical characteristics, describing a sample under investigation, from a set of tomographic projections. We present a technique for the evaluation of the reconstruction quality. The technique is based on the comparison of two images (phantom and reconstructed image) by means of the correlation coefficient and of the mean square error between them. In parallel, the correlation coefficient and mean square error are calculated for the wavelet transforms of the phantom and reconstructed images. The scales for the wavelet transform are chosen in agreement with the major geometric parameters of the phantom. Then the correlation coefficient of the wavelet transform with the chosen scale yields an evaluation of the quality of the phantom parameters reconstruction. The accuracy of the parameters reconstruction is determined by the mean square error for the selected scale. The phantom used for the analysis is a medium with randomly distributed grains. The distribution is characterized by two parameters: grain size and grain density (average number of grains per unit area). The parameters are used as the scales for the wavelet transform calculation. We make a comparison of the Algebraic Reconstruction Technique (ART) and the Filtered Back Projection Algorithm.]]></dc:description>

<dc:source><![CDATA[Grundwasser (2003)Ausgabe 4, 213-223]]></dc:source>
<dc:date>2003</dc:date>
<dc:description><![CDATA[Kolloide sind Bestandteile aller aquatischen Systeme. Das Verhalten der Kolloide in der Umwelt, deren Mobilisierung, Transport und Abscheidung und somit auch die Relevanz sind noch nicht vollständig verstanden. Dies liegt zum Teil an der Tatsache, dass die Kolloidanalytik extrem aufwändig ist. Sie gehört nicht zur Standardanalytik eines Wasserlabors. Keine Technik ist bisher zufriedenstellend in der Lage, Kolloide in ihrem gesamten Größenbereich auch bei geringsten Konzentrationen gleichzeitig zu quantifizieren und zu identifizieren. In der Regel ist eine Kombination von verschiedenen Techniken notwendig, um ausreichend Informationen über das Verhalten der Kolloide zu erhalten. Für die Bestimmung der Oberflächeneigenschaften stehen kaum Methoden zur Verfügung. Eine weitere, nicht zu unterschätzende Schwierigkeit ist die Probennahme und Probenaufbereitung. Für die Untersuchung von Kolloiden sind spezielle Probennahmetechniken und Protokolle notwendig, da ansonsten die ungestörten, natürlichen Bedingungen durch (Probennahme-)Artefakte maskiert werden. Dieser Artikel soll in Form einer Übersichtsarbeit Hinweise zur Probennahme geben und die verschiedenen Möglichkeiten der Kolloidanalytik aufzeigen.]]></dc:description>

<dc:title><![CDATA[Structural phase transformation of FePt nanoparticles by ion irradiation]]></dc:title>
<dc:source><![CDATA[Euromat 2005, 05.-08.09.2005, Prague, Czech Republic]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Owing to its large magneto-crystalline anisotropy energy, L1_0 ordered tetragonal FePt is among the most intensively discussed materials when it comes to pushing the superparamagnetic limit towards minimum particle sizes for future ultra-high density magnetic data storage media. Depending on the preparation technique, however, the formation of the L10 thermodynamic equilibrium phase is often impeded by either a lack of thermodynamic driving forces or a lack of diffusivity. 
Recently it has been shown that gas phase prepared FePt nanoparticles can exhibit a very narrow size distribution with a mean diameter of roughly 6 nm. Together with a packing density of 2.8 x 10^12 particles / cm^2 a potential data storage density of 18  Tbit / inch^2 could be achieved. Unfortunately these particles are superparamagnetic at room temperature due to their multiply twinned icosahedral structure. Therefore it is of essential importance to transform these nanoparticles into the favourable L10 phase in a post-deposition treatment. 
In the present study, post-deposition 5 keV He irradiation has been employed in order to perform the phase transformation of such gas phase prepared FePt nanoparticles. Structural characterization of the samples was carried out by means of High Resolution Transmission Electron Microscopy (HRTEM). After ion irradiation the previously multiply twinned icosahedral particles have transformed mostly into the single crystalline fcc structure. However, no indication for the chemically ordered L10 phase is found. This might be due to the fact that either the particles investigated are already smaller than a critical particle size below which the L10 phase is no longer the thermodynamic equilibrium phase in FePt, or kinetic aspects may be of increasing importance at these length scales.]]></dc:description>

<dc:description><![CDATA[I will discuss two recent advances related to semiconductor light sources in the infrared and THz regions. One example is a quantum cascade laser operating at a wavelength shorter than 4 microns above room temperature with high peak power. It is based on strained InGaAs/InAlAs on InP, with the addition of high barriers of pure AlAs for better confinement and strain compensation. In a novel few-cycle THz emitter we try to combine the advantages of the high electric bias field in photoconductive antennas with a large active area. This is achieved with an interdigitated electrode structure, partially covered in order to mask one field polarity. As a result no destructive interference of the emitted THz wave occurs, which allows upscaling of the device area.]]></dc:description>

<dc:description><![CDATA[Background
Bacteria play an important role in biogeochemical transformations and migration of uranium (U) in nature. In order to understand how U(VI) interacts with natural bacterial communities of U mining waste piles a series of microcosm experiments was  performed.
Methods
Several portions of a solid sample collected from the U mining waste pile near the city of Johanngeorgenstadt in Germany were supplemented with different amounts of U(VI), starting from the original 40 mg U/kg up to 300 mg/kg. 
The solubility of the U originally present and of the added U was assessed by selective sequential extraction (SSE). The composition of bacterial communities present in the original and in the supplemented with U samples was analyzed applying 16S rDNA retrieval by using 43F and 1404R degenerated primers. 
Results
SSE analysis demonstrated that in the original sample the main part of uranium was strongly bound in mineral phases. The bacterial community of this sample was predominated by Alphaproteobacteria and by representatives of Holophaga /Acidobacterium  phylum. 
The bacterial community structure of the sample was noticeable changed by increasing its U content to 100 mg/kg . No Holophaga/Acidobacterium and only a few representatives of Alphaproteobacteria were retrieved in this sample. Instead, a large number of sequences of mainly Gamma-Pseudomonas, and of Arthrobacter sp. were  found. The propagation of several populations of Deltaproteobacteria and especially of Geobacter sp. was induced in the sample as well. After 4 weeks of incubation,  most of the U added to this sample was still only weakly complexed. 
The bacterial community structure of the most contaminated sample, containing 300 mg U/kg, differed significantly from the two samples described above and depended on the aeration conditions during the incubation. In this sample the number of 16S rDNA sequences representing Cytophaga/Flavobacterium /Bacteroides  group was extremely high. Arthrobacter sp. populations were also identified but not as strongly predominant.   
Conclusions
The addition of U(VI) to a low contaminated U mining waste sample induces significant shifting in the indigenous bacterial populations. The effect of the added U(VI)seems to depend on its amount and on the redox conditions.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[Electrons confined in a flat semiconductor quantum dot with a parabolic in-plane potential act like a collective many-particle oscillator under coherent intraband excitation. We investigate theoretically the properties of these oscillators under a simultaneous scale transformation of the lateral dimensions and the electron occupation number. As the lateral size increases from a few nm (typical for self-assembled dots) to the mesoscopic regime, the physics of the system is changing qualitatively: Quantization effects gradually lose importance against Coulomb interactions and eventually the electron lake in a mesoscopic dot resembles a classical Wigner liquid. This parabolically confined "Wigner lake" behaves to the outside like a form-elastic "superparticle" of high charge. It can be coherently controlled by THz dipole radiation just like a single electron, but with reduced Brownian diffusion in the phonon heat bath. We propose a flexible method to fabricate single mesoscopic!
  dots of a controlled shape, Coulomb-coupled groups of dots, and almost arbitrary potential landscapes, using current semiconductor technology. As a first example, the collective modes of two Coulomb-coupled superparticles in neighboring dots are calculated. Also, we consider the possibility of steering a superparticle with shaped laser pulses to follow any complex two-dimensional orbit.]]></dc:description>

<dc:description><![CDATA[Thin beta-FeSi2 layers have been prepared by ion beam synthesis (IBS) on (111)Si substrates. The obtained samples have been characterized by means of infrared and Raman spectroscopies. The infrared (IR) transmittance spectra show the absorption at 310 cm(-1) as an indication of the initial nucleation of beta-FeSi2 precipitates during the implantation of iron into silicon substrate. The main feature of the photoluminescence (PL) measurements at 12 K in the beta-FeSi2/(111)Si samples annealed at 850 degreesC for 90 min is an intense peak localized at 0.811 eV. This peak is assigned to optical radiative transitions intrinsic to beta-FeSi2. (C) 2004 Elsevier Ltd. All rights reserved.]]></dc:description>

<dc:description><![CDATA[Uranium is present in the Earths crust at an average concentration of 2 mg/kg, similar to As and Mo, but ten times higher than Sb. It is enriched in granitic and phosphate rocks, lignite and monazite sands, and occurs in numerous minerals, uraninite (pitchblende), carnotite, and autunite being most abundant. During mining and ore processing (World production of U 35,000 Mg/a), these relatively insoluble, U(IV) and/or U(VI) containing minerals are converted into highly soluble and mobile U(VI) aqueous species, which may present an immediate risk for the environment, or are converted back to less mobile chemical forms. We will give an overview of processes, which influence the fate of U in this greatly perturbed biogeochemical cycle.
	Even at low redox potential and in equilibrium with uraninite, the aqueous solution of soils, the vadose zone and aquifers is dominated by U(VI) species. The extremely complex speciation of U(VI) is influenced by pH, dissolved carbonate and the presence of organic ligands. The mobility of these species is reduced by sorption processes to minerals, insoluble natural organic matter, and biota. On the other hand, the presence of carbonate and organic ligands with strong affinity for uranyl may prevent sorption to surfaces and enhance the mobility. The migration of U is furthermore influenced by the formation of, or sorption to mobile colloids.
	A strong immobilization of U presents the reduction to U(IV) and the subsequent precipitation as uraninite or other minerals. This process may proceed as a catalytic reaction on inorganic surfaces. Microorganisms, however, which are abundant even in U waste piles with high heavy metal concentrations, may be more important for U(IV) mineral precipitation. Processes involved are a direct biological reduction of U(VI) or an indirect reduction by changing redox potential and pH of the aqueous solution. Microorganisms can reduce the U mobility also by processes like bioaccumulation and biomineralization. Alternatively, particular groups of microorganisms can mobilize U from the ores by direct and indirect (metabolic-conducted) oxidation of U(IV), a process called bioleaching. Microorganisms can also increase the U mobility by releasing chelating ligands into the environment. Thus, they play one of the key roles in the biogeochemical cycling of U.]]></dc:description>

<dc:description><![CDATA[Open charm mesons (pseudo-scalar and scalar as well as axial-vector and vector) propagating or resting in nuclear matter display an enhanced sensitivity to the chiral condensate. This offers new prospects for seeking signals of chiral restoration, in particular in pA and \bar{p}A  reactions as envisaged in first-round experiments by the CBM and PANDA collaborations at FAIR. Weinberg-type sum rules for charming chiral partners are presented, and the distinct in-medium modifications of open-charm mesons are discussed. We also address the gluon condensates near Tc and their impact on QCD sum rules.]]></dc:description>

<dc:description><![CDATA[We present a novel concept for optical undulators that avoids the restrictions by the Rayleigh limit and thus allows to define interaction length and diameter independent of each other. With an ultrashort, high-power laser pulse in an oblique angle scattering geometry using tilted pulse fronts, electrons and laser remain overlapped while both beams travel over distances much longer than the Rayleigh length. For small scattering angles (<10°), where dispersive effects become negligible and interaction lengths scale up to the meter range, we discuss with the help of 1D-calculations the possibility of entering the SASE-FEL regime using optical undulators driven by existing lasers.]]></dc:description>

<dc:title><![CDATA[Potential energy retention of highly charged ions in solid surfaces]]></dc:title>
<dc:source><![CDATA[12th International Conference on the Physics of Highly Charged Ions, 06.-11.09.2004, Vilnius, Lithuania]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[In the interaction of highly charged ions with solid surfaces a main interest lies in the study of the dissipation channels for the potential energy. A large amount of information about secondary electron emission and X-ray emission has been collected in the past, enlightening the physics of the relaxation process of HCIs at surfaces. Calculating the amount of energy, which is dissipated into these channels only 10% to 15% is obtained. Less information is available about the absolute amount of the potential energy, which is deposited into the surface. In view of possible applications of HCIs for surface modifications the knowledge of this amount is essential. 
In order to study the energy retention of the potential energy of HCIs into solid surfaces, we apply a calorimetric approach [1]. The ions (charge state q=2 .. 8) are extracted from an ECR ion source with 5 kV and decelerated to final kinetic energies down to 60 eV x q after beam transport and charge state separation. By using a liquid-nitrogen cooled calorimetric setup the retention of the total energy, kinetic and potential, is determined via the temperature increase during the bombardment. Measuring the energy retention at kinetic energies from 200  60 eV and extrapolating to 0 eV kinetic energy the separated potential energy is obtained. The experiments were done on clean Cu, Si, and SiO2 surfaces.
Here, we present a comparative study of the relative retention coefficients of the potential energy for the metallic, semiconductor, and insulator surfaces. In addition, measurements of the secondary electron yield are taken into consideration for a detailed picture of the energy dissipation channels.

<dc:description><![CDATA[Cone-beam type X-ray CT is a potential mehtod to measure three-dimensional phase-distribution in vessels. An example for that is the measurement of gas profiles in stirred chemical reactors. Such data is highly valuable for the assessment and evaluation of chemical processes, for optimisation of the reactor and stirrer design, and for evaluation of computational fluid dynamics codes used to model the fluid flow and heat transer in reactive systems. However, there are considerable difficulties for accurate quantitative measurements, for instance of average gas fraction in a fluid, due to beam hardening and radiation scattering effects. In a theoretical and experimental work we have investigated the non-linear effect of both physical phenomena and developed a suitable measurement setup as well as calibration and software correction methods to achieve a highly accurate void fraction measurement with X-ray cone-beam tomography.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[We present new measurements of the Be-7(p,gamma)B-8 cross section from (E) over bar (cm) = 116 to 2460 keV. Our new measurements lead to S-17(0) = 22.1 +/- 0.6(expt) +/- 0.6(theor) eV b based on data from (E) over bar (cm) = 116 to 362 keV, where the central value is based on the theory of Descouvemont and Baye. We compare our results to other S-17(0) values extracted from both direct (Be-7(p, gamma)B-8) and indirect (Coulomb dissociation and heavy-ion reaction) measurements, and show that the results of these 3 types of experiments are not mutually compatible. We recommend a "best" value, S-17(0) = 21.4 +/- 0.5(expt) +/- 0.6(theor) eV b, based on the mean of all modern direct measurements below the 1(+) resonance.]]></dc:description>

<dc:source><![CDATA[Nuclear Physics A 746(2004), 483C-486C]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[Knowledge of the influence of nuclear shell structure on the survival probability of heavy compound nuclei against fission is important for a quantitative understanding of the production rates of spherical super-heavy elements (SHE). Fission probabilities of N = 126 isotones beyond astatine can be used as test cases for the production of spherical super-heavy elements, as those isotones possess a strong shell correction energy and are highly fissile. Here, we report on two new experimental approaches which probe the effect of the closed neutron shell at N = 126 on the competition between fission and particle evaporation using projectile fragmentation and electromagnetic-induced fission of radioactive beams. We conclude that these nuclei lose at least a great part of their stability against fission at low excitation energies and angular momenta-mostly due to the influence of collective contributions in the level density. Implications on the production of spherical SHE will be!
  discussed.]]></dc:description>

<dc:description><![CDATA[In the past several years, environmental sciences have increased their share in the research portfolios of many synchrotrons, not least for their topicality from a societal point of view. As this field overlaps with many other disciplines, the ESRF decided to establish, in 2005, a dedicated Review Panel for Environmental Science and Cultural Heritage.
This facility report summarizes recent trends and results from the ESRF to highlight the different disciplines, techniques and topics. It should also be noted that environmental studies encompass both a better understanding of natural phenomena and monitoring the impact of human activity on nature.]]></dc:description>

<dc:title><![CDATA[Quantitative zinc speciation in soil with XAFS spectroscopy: Evaluation of iterative transformation factor analysis]]></dc:title>
<dc:source><![CDATA[Physica Scripta T115(2005), 1038-1040]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[We employed a combination of selective sequential extractions and bulk XAFS spectroscopy, and extracted spectral XAFS components and their concentrations by iterative transformation factor analysis (ITFA), in order to determine the Zn speciation in a smelter-contaminated, acidic soil. We compared the speciation by ITFA with one we performed earlier using principal component analysis and linear combination fit. ITFA identified 4 different species, two different franklinite-type phases (Zn-Fe spinels), sphalerite (Zn sulfide) and Zn oxalate, the latter forming as a precipitate during chemical extraction with oxalate solution. The second spinel-type phase could be extracted with the help of ITFA, although no appropriate reference sample was available. Spinel 1 and 2 have Zn-O distances of 1.96 and 1.99 Å, and Zn-Fe distances of 3.53 and 3.48 Å, respectively. The results from ITFA gave much better fits of experimental spectra and are better in line with elemental mapping and XAFS microspectroscopy. The major advantage of investigating XAFS data with ITFA is the possibility to derive all species even when part of the references are not available.]]></dc:description>

<dc:source><![CDATA[Applied and Environmental Microbiology 71(2005)9, 5532-5543]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Bacillus sphaericus JG-A12 is a natural isolate recovered from a uranium mining waste pile near the town of Johanngeorgenstadt in Saxony, Germany. The cells of this strain are enveloped by a highly ordered crystalline proteinaceous surface layer (S-layer) with an ability to bind uranium and other heavy metals. By using a phosphoprotein specific staining, Inductive Coupled Plasma- Mass Spectrometry (ICP-MS) analysis and a colorimetric method, purified and recrystallized S-layer proteins were shown to be phosphorylated. We used Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy to determine the structural parameters of the uranium complexes formed by purified and recrystallized S-layer sheets of B. sphaericus JG-A12. In addition, the complexation of uranium by the vegetative bacterial cells was studied. The EXAFS analysis demonstrated that in all samples studied, the U(VI) is coordinated to carboxyl groups in a bidentate fashion with an average distance between the U atom and the C atom of 2.88 ± 0.02 Å, and to phosphate groups in a monodentate fashion with an average distance between the U atom and the P atom of 3.62 ± 0.02 Å. Transmission Electron Microscope (TEM) analysis showed that the uranium accumulated by the cells of this strain is located at the cell surface as dense deposits.]]></dc:description>

<dc:description><![CDATA[The capabilities of the in-house code FLOCAL and of the code ATHLET (developed by GRS, Germany) to reproduce instabilities of natural circulation BWRs at low pressure will be shown. FLOCAL consists of a 4-equations two-phase model. This code is the thermalhydraulic module of the three-dimensional neutronic codes DYN3D, also in-house development of FZR. The code ATHLET is a general-purpose thermalhydraulic code which has the possibility of using 4, 5 or 6-equations two-phase model. This code has been coupled with DYN3D. The results of the simulation obtained with the two codes are compared with experiments carried out with facilities built at Delft University of Technology (The Netherlands) and at Paul Scherrer Institute (PSI, Switzerland). The phenomenology of the instabilities is very well reproduced by the two codes. Good quantitative agreement is found as well.]]></dc:description>

<dc:description><![CDATA[We determined Sb speciation in 9 soil samples from 6 Swiss shooting ranges using Sb K-edge EXAFS spectroscopy and advanced statistical data analysis methods (ITFA). Despite the high variability in Geology, pH (3.1 - 7.5) and Sb concentrations (1000 - 17000 mg/kg), we found only two species: metallic Sb(0) and Sb(V) forming inner-sphere sorption complexes on Fe oxide surfaces. The relative amount of Sb(0) ranged from 0 to 75 %, the relative amount of Sb(V) ranged from 25 to 100 %. Distribution between the two species was not explained by any of the measured variables. No evidence for Sb(III) was found in the bulk samples. To the best of our knowledge this is the first quantitative determination of the chemical Sb forms in bulk soil samples.]]></dc:description>

<dc:description><![CDATA[Colloids can either stimulate or retard the transport of actinides. Environmental colloids are formed by a variety of mechanisms. The most important one is the precipitation of secondary phases. There have already been several publications on colloid generation within water bod-ies due to chemical reactions after the mixing of waters of different chemical composition or after access of air. Much less information exists about a different mechanism of colloid for-mation in the nature  the direct production of secondary mineral colloids at the water-rock interface by the weathering of rock material.

The formation of colloids during the weathering of ground phyllite from an abandoned ura-nium mine and the sorption of uranium(VI) onto these colloids were studied. Centrifugation and ultrafiltration were applied. A method to differentiate between the primary mineral col-loids of the phyllite and the precipitated secondary mineral colloids was developed. 

Significant amounts of colloids of the 101 to 102 nm size class were found in the suspension of ground phyllite after weathering times of 87 h to 792 h. Considerable fractions (up to 10 mg/L) of these 101 to 102 nm colloids consisted of secondary minerals. The following compo-sition of the freshly precipitated colloids is to be expected: Ferihydrite, aluminosilicates, amorphous Al(OH)3, gibbsite, possibly iron silicates, possibly iron-alumino silicates. It should be emphasized that a significant fraction of the secondary mineral colloids was composed of iron(III) compounds which is of relevance for the sorption behaviour of these colloids. A more detailed mineralogical characterization of the colloids is underway. The 101 to 102 nm secondary mineral colloids were relatively stable and remained in colloidal suspension over longer periods of time.

The direct formation of secondary mineral colloids at the mineral-water interface by the weathering of rock material is an alternative to the well-known mechanism of colloid forma-tion by the mixture of different water bodies or by aeration of a water body. This direct mechanism of colloid production occurs during the weathering of freshly crushed rock in the unsaturated zone as for instance crushed rock in mine dumps. Colloids produced by this mechanism can influence the transport of actinides since they have a large specific surface area and a high sorption affinity for heavy metals. This was demonstrated for uranium(VI).]]></dc:description>

<dc:source><![CDATA[Journal of Applied Physics 108(2010), 043503]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Periodic precipitation patterns in C:Ni nanocomposites grown by energetic ion co-deposition are investigated. Films were grown at room temperature by ionized physical vapor deposition using a pulsed filtered cathodic vacuum arc. We reveal the role of the film composition, ion energy and incidence angle on the film morphology using transmission electron microscopy and grazing incidence small angle x-ray scattering. Under these growth conditions, phase separation occurs in a thin surface layer which has a high atomic mobility due to energetic ion impacts. This layer is an advancing reaction front, which switches to an oscillatory mode, producing periodic precipitation patterns. Our results show that the ion induced atomic mobility is not random, as it would be in the case of thermal diffusion, but conserves to a large extent the initial direction of the incoming ions. This results in a tilted pattern under oblique ion incidence. A dependence of the nanopattern periodicity and tilt on the growth parameters is established and pattern morphology control via ion velocity is demonstrated.]]></dc:description>

<dc:source><![CDATA[The European Conference on Physics of Magnetism'05, 24.-27.06.2005, Poznan, Poland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Using magnetron sputter deposition a number of glass/Ta 7nm/PtMn 20nm/CoFe 4nm/Ta 4nm samples with large exchange bias field were prepared for magnetic pattering investigations. By means of optical lithography and physical etching several patterns with decreasing lateral sizes of either the elements or the spacing between the elements were prepared. The largest square is 50 x 50 µm2 and the smallest only 1 µm2. The separating lines range from 10 µm to 2 µm width. The magnetic characterization of the samples was done by VSM and MOKE. Kerr microscopy and MFM investigations in an applied magnetic field have been performed in order to get a deeper understanding of the domain pattern. All images show a monodomain magnetization state in zero magnetic field. The shape of the structure itself dose not influence the magnetization direction. The shape anisotropy contribution is thus smaller than the unidirectional anisotropy given by the exchange bias. In addition 5 keV He+ ion irradiation was used to decrease exchange bias field value and thereby modify the ratio between unidirectional and shape anisotropy. The magnetic domain structure is investigated as a function of this ratio.]]></dc:description>

<dc:title><![CDATA[First Results from SHIP Experiment]]></dc:title>
<dc:source><![CDATA[Fusion Science and Technology 47(2005)1T, 59-62]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[At present, the GDT facility of the Budker Institute of Nuclear Physics Novosibirsk is being upgraded. The first stage of the upgrade is the Synthesized Hot Ion Plasmoid (SHIP) experiment. It aims, on the one hand, at the investigation of plasmas the parameters of which are expected to appear in the region of high neutron production in a GDT based fusion neutron source as proposed by the Budker Institute and, on the other hand, at the investigation of plasmas the parameters of which have never been achieved before in magnetic mirrors. 
The experiment is performed in a small mirror section which is installed at the end of one side of GDT. The magnetic field on axis is in the range of 0.5-20 Tesla and the mirror ratio is 1.2-1.4. The mirror is filled with background plasma streaming in from the central cell. This plasma component is maxwellized and has an electron temperature of about 100 eV. Two neutral beam injectors perpendicularly inject a total current of about 50 Atom Amperes of deuterium neutrals with an energy of 20 keV 
as a pulse with a duration of about 1 ms. Ionization of the beams generates the high-energy ion component. The device has been equipped with several diagnostic methods which are successfully used in GDT experiments.
The paper presents first results of plasma parameter measurements in the SHIP experiment.]]></dc:description>

<dc:description><![CDATA[At present, the GDT facility of the Budker Institute of Nuclear Physics Novosibirsk is being upgraded. The first stage of the upgrade is the Synthesized Hot Ion Plasmoid (SHIP) experiment. It aims, on the one hand, at the investigation of plasmas the parameters of which are expected to appear in the region of high neutron production in a GDT based fusion neutron source as proposed by the Budker Institute and, on the other hand, at the investigation of plasmas the parameters of which have never been achieved before in magnetic mirrors. 
The experiment is performed in a small mirror section which is installed at the end of one side of GDT. The magnetic field on axis is in the range of 0.5-20 Tesla and the mirror ratio is 1.2-1.4. The mirror is filled with background plasma streaming in from the central cell. This plasma component is maxwellized and has an electron temperature of about 100 eV. Two neutral beam injectors perpendicularly inject a total current of about 50 Atom Amperes of deuterium neutrals with an energy of 20 keV 
as a pulse with a duration of about 1 ms. Ionization of the beams generates the high-energy ion component. The device has been equipped with several diagnostic methods which are successfully used in GDT experiments.
The paper presents first results of plasma parameter measurements in the SHIP experiment.]]></dc:description>

<dc:description><![CDATA[Upon substituting Ca for Eu in the local-moment ferromagnet EuB<sub>6</sub>, the Curie temperature <em>T<sub>C</sub></em>
decreases substantially with increasing dilution of the magnetic sublattice and is completely suppressed
for <em>x</em> ≤0:3. The Ca substitution leads to significant changes of the electronic properties across the
Eu<sub><em>x</em></sub>Ca<sub>1-<em>x</em></sub>B<sub>6</sub> series. Electron microscopy data for <em>x</em> ≈ 0.27 indicate a phase separation into Eu- and
Ca-rich clusters of 5 to 10 nm diameter, leading to percolation-type phenomena in the electrical
transport properties. The related critical concentration <em>x</em><sub>p</sub> is approximately 0.3. For <em>x</em> ≈ 0.27, we
observe colossal negative magnetoresistance effects at low temperatures, similar in magnitude as those
reported for manganese oxides.]]></dc:description>

<dc:title><![CDATA[Anisotropy of Thermal Conductivity and Possible Signature of the Fulde-Ferrell-Larkin-Ovchinnikov state in CeCoIn<sub>5</sub>]]></dc:title>
<dc:source><![CDATA[Physical Review B 70(2004)134513, 1-7]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[We have measured the thermal conductivity of the heavy-fermion superconductor CeCoIn<sub>5</sub> in the vicinity of the upper critical field, with the magnetic field perpendicular to the <em>c</em> axis. Thermal conductivity displays a discontinuous jump at the superconducting phase boundary below critical temperature <em>T</em><sub>0</sub>≈1 K, indicating a change from a second- to first-order transition and confirming the recent results of specific heat measurements on CeCoIn<sub>5</sub>. In addition, the thermal conductivity data as a function of field display a kink at a field <em>H<sub>k</sub></em> below the superconducting critical field, which closely coincides with the recently discovered anomaly in specific heat, tentatively identified with the appearance of the spatially inhomogeneous Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) superconducting state. Our results indicate that the thermal conductivity is enhanced within the FFLO state, and call for further theoretical investigations of the order parameters real-space structure (and, in particular, the structure of vortices) and of the thermal transport within the inhomogeneous FFLO state.]]></dc:description>

<dc:source><![CDATA[Physical Review B 69(2004)132407, 1-4]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[We have combined the results of magnetization and Hall effect measurements to conclude that the ferromagnetic moments of lightly doped CaB<sub>6</sub> samples display no systematic variation with electron doping level.
Removal of the surface with acid etching substantially reduces the measured moment, although the Hall constant and resistivity are unaffected, indicating that the ferromagnetism largely resides on and near the sample surface. Electron microprobe experiments reveal that Fe and Ni are found at the edges of facets and growth steps, and on other surface features introduced during growth. Our results indicate that the weak ferromagnetism previously reported in undoped CaB<sub>6</sub> is most likely of extrinsic origin.]]></dc:description>

<dc:description><![CDATA[A multiple velocity multiple size group (NxM MUSIG) model was developed for inhomogeneous poly-dispersed multiphase flows in cooperation with ANSYS CFX. The model is constructed by incorporating the population balance equation into the multi-fluid modeling framework. The dispersed phase is allowed to be classified into $N$ continuum fields (velocity groups) according to their hydrodynamic behaviors; each group allowing an arbitrary number of sub-size classes. This model has generalized all possible class model variants and is applicable to large-scale computations. As a pre-investigation for the CFX5.8 development, the Nx1 variant was implemented based on CFX5.7 and applied to investigate as-liquid flows in a vertical pipe. The results confirm that this model is capable of predicting the separation of bubbles of different sizes and the development of the gas volume fraction along the pipe.]]></dc:description>

<dc:description><![CDATA[We performed silicon diffusion experiments with sol-gel derived isotopically enriched silica glasses at temperatures between 1050°C and 1300°C. The diffusion profiles were measured by means of time-of-flight secondary ion mass spectrometry. Samples annealed in closed silica ampoules under argon or dry air reveal enhanced Si diffusion compared to Si diffusion in fused silica. On the other hand, annealing in a large alumina tube under <sup>18</sup>O<sub>2</sub> ambient yields Si and O diffusion coefficients which approach the results for thermally grown SiO<sub>2</sub>. The enhanced Si diffusion in sol-gel derived glass is proposed to be due to water residues which lead to the formation of silanol SiOH groups.]]></dc:description>

<dc:description><![CDATA[A start-up procedure for natural-circulation Boiling Water Reactors is illustrated. The procedure, developed in order to avoid flashing-induced instabilities at low pressures and low powers, does not require any additional system. The reactor vessel is pressurized while steam is produced outside the core and riser sections. In this way, the firsts stage of the pressurization takes place with the reactor operating in single-phase natural-circulation conditions, thus without occurrence of flashing-induced flow oscillations. At the same time, a smooth steam production and pressurization of the system is achieved. A simple analytical model is applied to the ESBWR of General Electric to have a first impression on the order of magnitude of the parameters involved and to verify whether the start-up of the reactor can be achieved in reasonable times. The feasibility of the procedure is then studied in details by means of the ATHLET code (Lerchi and Austregesilo, 2003), developed by GRS (Germany). This code has been successfully qualified against low-pressure flashing-induced instabilities within the framework of the EU project NACUSP]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[To improve the performance of critical part components, new methods for surface strengthening are being developed with success, like plasma immersion ion implantation (PIII) and hybrid surface treatments mixing PIII and ion nitriding processes. A combination of high pressure (4 x 10(1)Pa), moderate temperature (up to 450degreesC) glow discharge nitriding with low pressure (8 x 10(-2)Pa) and low DC bias voltage ion nitriding (or DC PIII) was implemented. Depending on the particular conditions of the treatment and the depth probed, mixed phases of gamma(N) and epsilon were measured in the treated SS304 steel sample. This near surface modification resulted in an improved hardness (up to a factor of 2.7 x) of the sample which could also enhance its wear properties. Surface modification of T16Al4V alloy and SS304 steel by a combination of PIII and subsequent ion nitriding was investigated as well. Nitrogen ions were implanted into the specimens at 15 keV and then ion nitrided at !  low pressure (7 x 10(-2)Pa) with a bias of -800 V. Compared to the untreated samples, the hardness of Ti6Al4V alloy and the steels could be improved significantly. AES results indicated high retained doses in both samples, confirming the high efficiency of this hybrid process.]]></dc:description>

<dc:description><![CDATA[A PtMn/NiFe exchange bias system with an exchange bias field of 180 Oe was magnetically patterned by means of a low fluence focused ion beam. A 1 µm wide stripe pattern with the long axis (1000 µm) oriented parallel to the exchange bias field direction has been irradiated by 2x10<sup>14</sup> Ga<sup>+</sup>/cm<sup>2</sup>. In the irradiated area the coercivity is reduced and the exchange bias field vanishes, while in the nominally non-irradi-ated region between the irradiated stripes the exchange bias field is reduced to approximately 35 Oe. This reduction is attributed to the magnetic coupling of the irradiated stripes to their intervening non-irradiated regions. Magnetic domain imaging by means of Kerr microscopy and magnetic force microscopy support this interpretation.]]></dc:description>

<dc:description><![CDATA[In this work, junctions with reduced Hf coupling were fabricated by ion beam deposition and oxidation, using CoFeB electrodes. The CoFeB layer has a strong (110) texture that can be the origin of lower Hf and coercivity when compared with CoFe. Junctions processed down to 2x4 um2 with 40Å thick CoFeB bottom electrodes have 42% of tunneling magnetoresistance (TMR), (R x A ~400 Ohm um2), Hc of ~10 Oe and Hf of ~2 Oe. CoFe-based junctions (R x A ~500W Ohm um2) have lower TMR (~35%) and larger Hf (~5-6 Oe) and Hc (~12-14 Oe). Local chemical composition analysis of the cross section indicated Fe-O segregation without Co grown on top of the barrier for CoFe-based junctions and not for CoFeB ones.]]></dc:description>

<dc:description><![CDATA[Low resistance spin-dependent tunnel junctions are investigated for read-head applications due to their large tunneling magnetoresistance effect and low junction resistance-area product. Typical full junction structures can be Ta 70Å/NiFe 70Å/MnIr 80Å/CoFe 35Å/Hf(x)Al(y)O(z) t/CoFe 35Å/NiFe 40Å/Ta 30Å, with t around 10 Å, annealed to temperatures up to 250ºC. We analysed simpler structures with RBS experiments at a grazing angle of incidence in order to study the junction only. Heavy ion- and He-ERDA experiments were also done. The composition of the HfAlO barrier is determined, showing that a slightly substoichiometric oxide is formed. On annealing at 240ºC, the interfaces of the barrier become sharper. TEM results confirm that the barrier is continuous after annealing. This is related to an increase in the tunnel magnetoresistance signal from 4% to 13.5% after annealing.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[B-C-N thin films of a wide composition range were deposited by reactive d.c. magnetron sputtering of targets with different B/C ratio in an Ar/N2 atmosphere. The bonding characteristics of these amorphous films were investigated by Fourier-transformed infrared spectroscopy and X-ray photoelectron spectroscopy. The results of both characterisation methods indicate that real ternary compounds in which all three elements are bound to each other are only formed when at least one element has a low concentration in the film (and therefore could be considered as an impurity). Otherwise the deposited material tends to a phase separation into binary compounds and single phases.]]></dc:description>

<dc:description><![CDATA[Surface chemistry during wet chemical etching in alkaline KOH solution and dry etching in SF6/O2 plasma of high dose Ga+ implanted Si has been investigated by means of  secondary ion mass spectroscopy (SIMS) and x-ray induced photoelectron spectroscopy (XPS). During wet chemical etching in a KOH/H2O solution a thin layer of  GaOx of < 1 nm thickness is formed, which has been investigated more in detail by angle-resolved XPS.. In the case of dry reactive ion etching the surface chemistry is quite different. In this case a more enhanced oxidation of Ga takes place due to the high reactivity of atomic oxygen from the SF6/O2 plasma. SIMS results show that during RIE a Ga rich surface layer forms and therefore an enhanced Ga oxidation takes place leading to a thicker GaOx layer compared to wet chemical treatment. XPS depth profiling points at a stoichiometry of nearly completely oxidized Ga (Ga2O3) layer free from Si with a thickness of about 5 ... 10 nm. The etch rate lowering in Ga+ as- implanted silicon is ascribed to the formation of gallium oxide at the Si surface during the etch processes.]]></dc:description>

<dc:description><![CDATA[Oxidative modification of low-density lipoprotein (LDL) is regarded as a crucial event in atherogenesis. Assessing the metabolic fate of oxidized LDL (oxLDL) in vivo with radiotracer techniques is hindered by the lack of suitable sensitive and specific radiolabeling methods. We evaluated an improved methodology based on the radiolabeling of native LDL (nLDL) and oxLDL with the positron emitter fluorine-18 ((18)F) by conjugation with N-succinimidyl-4-[(18)F]fluorobenzoate ([(18)F]SFB). We investigated whether radiolabeling of LDL induces adverse structural modifications. Results suggest that radiolabeling of both nLDL and oxLDL using [(18)F]SFB causes neither additional oxidative structural modifications of LDL lipids and proteins nor alteration of their biological activity and functionality, respectively. Thus, radiolabeling of LDL using [(18)F]SFB could prove to be a promising approach for studying the kinetics of oxLDL in vivo.]]></dc:description>

<dc:description><![CDATA[The diffusion of humic acid (HA) in Georgia kaolinite KGa-1B was studied. The compacted clay plug was conditioned with a 0.01 M NaClO4 + 1 mM NaN3 solution at pH 5.2. The effective porosity ε and the effective diffusion coefficient De of water were determined using tritiated water (HTO). A synthetic 14C-labeled HA type M42 with a concentration of 11.0 mg/L and a specific activity of (17.0 ± 0.5) MBq/g was used as tracer. We applied a steady-state through-diffusion technique with constant gradient. The particle size distribution of HA was determined by ultrafiltration.

The migration of HA in compacted clay is governed by diffusion. However, compared to an ionic tracer some characteristics are observed. The De values found for HA (2·10^13 to 2·10^12 m^2/s) are about two to three orders of magnitude lower than that of HTO. Likewise the rock capacity factor α(HA) amounts to only 10 % to 50 % of ε. The spatial extension of the humic colloids constricts their mobility in the narrow pore space thus increasing the tortuosity of the diffusion path and decreasing the pore volume accessible for HA. This phenomenon is referred to as size exclusion effect. In [1] a significant adsorption of HA on KGa-1B was found (Kd = 680 ml/g at pH 5.2) which would result in a value for α above unity. Obviously, the size exclusion dominates the HA migration.
The particle size distributions of the high and the low concentration reservoir differ significantly. The mean particle size shifts from about 50 kD in the high to less than 1 kD in the low concentration reservoir. Only small particles are able to pass the pore system. This is in agreement with the HA distribution in the clay plug where most of the tracer was found at the high concentration boundary.]]></dc:description>

<dc:description><![CDATA[Microbes are widely distributed in nature and they can strongly influence the migration of actinides in the environment. Microorganisms in concentrations of 1x103 to 5x106 cells ml-1 were estimated by Pedersen et al. in the aquifer system of the Äspö Hard Rock Laboratory (Äspö HRL) in Sweden. The number of sulfate-reducing bacteria (SRB) was between 101 to 2x104 cells ml-1. We investigated the interaction of the SRB Desulfovibrio äspöensis, DSM 10631T, with plutonium. The 242Pu was provided as a mixture of ca. 46% Pu(VI) and ca. 34% Pu(IV)-polymer. Interactions between bacteria and plutonium in mixed oxidation states were not yet intensively investigated. 
In this study, accumulation experiments were performed in order to obtain information about the amount of the Pu bound by bacteria in dependence on the contact time and the [Pu]initial at pH 5. We used liquid-liquid-extractions and absorption spectroscopy to determine the Pu speciation. In agreement with the results obtained with U(VI) [2] and Np(V), we found a strong dependence of the amount of accumulated Pu with [Pu]initial. Based on our results and taking into consideration the findings of Panak et al. [3], we developed a model describing the interaction of Pu(VI) and Pu(IV)-polymers with D. äspöensis. In a first step, the Pu(VI) and Pu(IV)-polymers are bound to the biomass. The Pu(VI) is reduced to Pu(V) due to the activity of the cells within the first 24 h of contact time. Most of the formed Pu(V) dissolves due to the weak complexing properties. The dissolved Pu(V) disproportionates to Pu(IV) and Pu(VI) which are then interacting with functional groups of the cell surface structure. Indications were found also for a penetration of Pu species inside the bacterial cells.

<dc:date>2003</dc:date>
<dc:description><![CDATA[We measured the specific heat and resistivity of heavy fermion CeCoIn<sub>5</sub> between the superconducting critical field <sub>c2</sub> = 5 T and 9 T, with the field in the [001] direction, and at temperatures down to 50 mK. At 5 T the data show a non-Fermi liquid (NFL) behavior down to the lowest temperatures. At the field above 8 T the data exhibit a crossover from the Fermi liquid to a non-Fermi liquid behavior. We analyzed the scaling properties of the specific heat and compared both the resistivity and the specific heat with the predictions of a spin-fluctuation theory. Our analysis leads us to suggest that the NFL behavior is due to incipient antiferromagnetism (AFM) in CeCoIn<sub>5</sub> with the quantum critical point in the vicinity of H<sub>c2</sub>. Below H<sub>c2</sub> the AFM phase which competes with the paramagnetic ground state is superseded by the superconducting transition.]]></dc:description>

<dc:source><![CDATA[XTOP 2010 / 10th Biennial Conference on High Resolution X-Ray Diffraction and Imaging, 20.-23.09.2010, University of Warwick, UK]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Focused ion beam irradiation can be used as a tool for creation of magnetic nanos-tructures. Previous studies have shown that FIB irradiation of thin metallic films could induce significant grain growth and therefore modify magnetic properties [1-2]. In this work we compare X-ray diffraction studies with magnetic properties that were characterized by magneto-optic Kerr effect sensing both the in-plane and the out-of-plane components of the magnetization.
A 50nm thick permalloy layer (Ni80Fe20) irradiated with different fluences of Ga+ ions was chosen for the investigations of grain size and microstrain. Due to the small irradiated areas produced by FIB irradiation XRD measurements were carried out on an optimized X-ray laboratory setup with a focused X-ray beam of 200µm as well as on the ESRF ID01 facility using a 1µm focused beam. Figure 1a shows rocking curves of the (111) permalloy reflection and demonstrates the material texturing with increase of ion fluence as there is a narrowing in FWHM and a rise of intensity. Low irradiation fluences up to 6.24*10E15 ions/cm<sup>2</sup> modify the material and induce crystal-lite growth, whereas larger fluences completely destroy the crystalline structure. A further material crystallization should improve the magnetic properties. Due to the incorporation of Ga+ ions into the lattice additional softening of the permalloy film occurs and leads to the degradation of magnetic properties. In figure 1b a corre-sponding saturation Kerr rotation measurement is shown. It demonstrates a decrease of the magnetic moment with increasing ion fluence.

<dc:date>2004</dc:date>
<dc:description><![CDATA[Electromagnetic levitation is a well-known technique for containerless processing of metals and alloys both in the solid and in the molten state. In experiments the levitated bodies often times show different types of instabilities resulting in a rotating and oscillating motion of the sample. We present results on the reason of such spontaneous instabilities. The theoretical predictions are verified by model experiments using solid Al or Mg spheres. These instabilities can obviously be avoided by system parameters below the corresponding non-dimensional threshold. If this is not possible, an active damping method using DC magnetic fields has been developed. The DC field can either be produced by permanent magnets or by an electromagnetic superposition to the levitation coils. Experiments will be shown demonstrating the stabilization effect due to the DC magnetic fields.
Numerical simulations for the flow inside the molten levitated sample will be given as well as results for the linear stability of this internal flow. Flow and flow stability are also analyzed for the case of a molten droplet subject to a global rotation. It is shown that the global rotation may have a significant stabilizing influence on the internal flow field.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[The motion of single Argon bubbles rising in the eutectic alloy GaInSn under the influence of a DC longitudinal magnetic field was examined. The magnetic field strength was chosen up to 0.3 T corresponding to magnetic interaction parameters N of 1.5. The experiments were carried out in the following parameter range: 2500 < Re < 5500, 2 < Eo < 7, Mo = 2.4×10-13. The liquid metal was in a cylindrical container at rest. Bubble and liquid velocities were measured using the Ultrasound Doppler Velocimetry (UDV). The measured bubble terminal velocity showed oscillations indicating a zig-zag movement of ellipsoidal bubbles. Whereas for small bubbles (de £ 4.6 mm) an increase of the drag coefficient with increasing magnetic interaction parameter was observed, the application of the magnetic field reduces the drag coefficient of larger bubbles (de ³ 5.4 mm). The measurements revealed a distinct electromagnetic damping of the bubble induced liquid velocity leading to more rectilinear bubble trajectories. Moreover, significant modifications of the bubble wake structure were observed. Raising of the magnetic field strength causes an enlargement of the eddies in the wake. The Strouhal number St decreases with increasing magnetic interaction parameter.]]></dc:description>

<dc:description><![CDATA[Two cases are considered in order to study possible drag reductions due to the action of electromagnetic forces. 
1. A direct numerical simulation of a turbulent channel flow is performed. The unsteady Navier-Stokes equations and Poisson electric potential equation are solved at a Reynolds number Re=3000 and 6000, based on the laminar centreline velocity V0 and channel half-width d. The tau-collocation spectral method developed by J. Kim. et al. is used. The Crank-Nikolson method for the viscous and a third-order Runge-Kutta method for the nonlinear term and the Lorentz force are applied. The resolution was 64x65x64 in the streamwise, wall-normal and spanwise directions. For an electromagnetic actuator consisting basically of a spanwise oscillating force, we analysed the drag reduction and its efficiency for various load number. It is shown that a load number of order one leads to a significant increase of the efficiency in comparison to the standard case of high small load number.

2. For the flow around a sphere we found an internal alternating electromagnetic field source which leads to a strong drag reduction. The analysis is done in the Stokes approximation analytically and then at Reynolds number Re ~ 300 numerically using a pseudospectral code. A simple gradient-type optimisation was applied in order to tailor the magnetic field source for the purpose of a reduced drag. We considered the simplified case (decoupling of fluid flow and electromagnetic fields) of large load numbers, with the drawback that the strong drag reductions obtained are certainly inefficient from the energetical point of view.]]></dc:description>

<dc:description><![CDATA[This work is concerned with the convection in a finite cylinder driven by a rotating magnetic field. Both direct numerical simulation (DNS) and experiments have been carried out to study the characteristics of this kind of confined flows. A decoupling of the mathematical model into the Navier-Stokes equations and an a priori known Lorentz force was achieved in the usual manner by employing the rigid-body and the low-frequency approximations. Adams-Bashforth time integration has been combined with a second-order finite element method for the discretisation. Utilising the upcoming technique of Ultrasonic Doppler Velocimetry (UDV) allowed for a mapping of the meridional velocity components throughout an entire section of the container. In a more quantitative fashion potential difference measurements (PDM) were performed to support and validate the numerical results.]]></dc:description>

All our data may be rather well described across the entire temperature regime covered on the basis of a Debye-type relaxation-time approximation and by assuming the concurring influence of various scattering channels on the mean free path of the phonons. An unusual and strong resonance in the scattering rate of the phonons of all investigated materials is attributed to a strong interaction between acoustic itinerant and localized modes, the latter arising from oscillations of the metal cations around their equilibrium position.]]></dc:description>

<dc:description><![CDATA[We present a planar large-area photoconducting emitter for impulsive generation of terahertz (THz) radiation. The device consists of an interdigitated electrode metal-semiconductor-metal (MSM) structure which is masked by a second metallization layer isolated from the MSM electrodes. The second layer blocks optical excitation in every second period of the MSM finger structure. Hence charge carriers are excited only in those periods of the MSM structure which exhibit a unidirectional electric field. Constructive interference of the THz emission from accelerated carriers leads to THz electric field amplitudes up to 85 V/cm when excited with fs optical pulses from a Ti:sapphire oscillator with an average power of 100 mW at a bias voltage of 65 V applied to the MSM structure. The proposed device structure has a large potential for large-area high-power THz emitters.]]></dc:description>

<dc:source><![CDATA[Seminarreihe der Forschergruppe Magnetofluiddynamik, 20.10.2004, Ilmenau, Germany]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[For a physical modelling of hot and chemically aggressive metallic melts in industrial processes, the according experiments are done mostly on water. Besides the fact that the important influence of magnetic fields on the flow cannot be studied at all, the majority of these results are meaningless owing to the non-matching similarity criteria, such as for instance the Prandtl number in the case when thermal gradients are involved. Realistic models rely on low melting point metals the flow of which is not easily measurable by of the shelf equipment.
Rather than giving a systematic review of the measuring techniques available for liquid metal flows, the presentation will concentrate on electric potential probes (EPP) and the up and coming ultrasonic Doppler velocimetry (UDV). These methods will be compared with respect to their applicability and characteristics such as sensitivity, dynamic range,  and spatial as well as temporal resolution. Several practically orientated examples have been selected to demonstrate the state of the art performance of both these techniques.
In crystal growth processes rotating magnetic fields (RMFs) are often employed for homogenisation purposes while it is mandatory to keep the flow almost stationary. Well below the threshold of linear stability, the transition from the Stokes-regime to a laminar boundary layer flow was quantified by EPP.
The flow mapping capabilites of UDV have turned out to be a powerful tool for the determination of topological details of the convective pattern.
Scaling laws known from theory may be proved by precision measurements. This was done for the ~Ta2/3-dependence in the RMF by EPP and the ~B-characteristic in a single-phase AC (pulsating) magnetic field by UDV.
Whereas Kolmogorov-like spectra were obtained from the swirling flow, large scale structures with the according low frequency oscillations were found within the recirculation. A video prepared from a sequence of the correlated velocity information contained in each UDV-profile impressively shows the spatio-temporal behaviour of such coherent structures.
To complete with the modern developments in velocity measuring techniques in electrically conduction fluids, the principles of the inverse reconstruction from measurements of the flow-induced magnetic field outside the fluid volume will be outlined. A first benchmark of this method clearly shows its robustness and the ranges of applicability.]]></dc:description>

<dc:source><![CDATA[Radiochimica Acta 93(2005)9/10, 527-532]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The aim of this work is to illustrate the effect of parameter uncertainty (protolysis constants) in surface complexation modeling. As example the blind prediction of Np(V) sorption onto hematite was selected, applying the Diffuse Double Layer Model (DDLM). 
None of the pK parameter sets randomly generated within a space of two standard deviations did deliver unacceptable predictions for the distribution coefficients. Thus the formally large spreading of the pK values as extracted from literature (even after normalization and extrapolation to infinite dilution) is actually not critical.

<dc:description><![CDATA[The capabilities and limitations of wavelet analysis are demonstrated for the illustrative case of two practial applications: investigation of magneto-tunneling signals and the extended x-ray absorption fine structure (EXAFS) of uranium. A brief introduction to wavelet analysis is given. The term "window size" of the mother wavelet function is defined; this concept underlies one of the ideas for a criterion of optimal choice of the mother wavelet function. The capabilities of a software package developed by the authors are demonstrated; this software was used for all the calculations done in the course of this study.]]></dc:description>

<dc:description><![CDATA[Surface Complexation Models (SCM) can describe sorption processes at the mineral-fluid interface on a scientific, quasi-thermodynamic basis. The effect of parameter uncertainty in blind predictions is illustrated by the example of Np(V) sorption onto hematite.
The Diffuse Double Layer (DDL) model was chosen as SCM submodel to keep the number of parameters at a minimum. From the surface species reported so far, =FeOH<sub>2</sub><sup>+</sup>, =FeO<sup>-</sup>, =FeONpO<sub>2</sub>, =FeONpO<sub>2</sub>(HCO<sub>3</sub>)<sub>2</sub><sup>2-</sup>, =FeOHCO<sub>2</sub>, and =FeOCO<sub>2</sub><sup>-</sup> were selected with their normalized DDL reaction constants log K<sub>n</sub>, taken from the RES³T database (Brendler et al., 2003).
The modeling was performed with the FITEQL code, version 3.2. The predictions were evaluated by comparison with the experimental results by Kohler et al. (1999), comprising of 52 data points for the Np(V) sorption at varied pH, ionic strength, solid/liquid ratio, Np content, and air P<sub>CO2</sub>. When focusing on the conventional distribution coefficient K<sub>D</sub>, the maximum deviation for all data subsets is less than one order of magnitude, a spreading considered to be reasonable in performance assessment applications.
Because the protolysis constants can not be varied independently, the point of zero charge (PZC) and delta pK were calculated based on experimental pK<sub>1</sub> and pK<sub>2</sub>. Consequential we generated 20 independent pK data sets with the aid of Gaussian-distributed random numbers. None of these parameter sets did deliver unacceptable blind predictions for the distribution coefficients.
The formally large scatter of pK values as extracted from literature is actually not critical. Even the use of inconsistent values from other electrostatic models will yield similar results. For well-defined mineral systems, provided a suitable database is accessible, the SCM approach seems to be promising.

<dc:description><![CDATA[Eine in ruhendem Wasser aufsteigende Luftblase wird parallel zur Wasseroberfläche in zwei zueinander senkrechte horizontale Richtungen parallel projiziert. Diese beiden Projektionen werden zunächst als Ellipsen approximiert. Anhand der Ellipsen wird die Blase dann als Rotationsellipsoid modelliert. Das Rotationsellipsoid eignet sich zur Analyse des Verhaltens von Blasen auf ihrem Weg durch das Wasser. Dies wird an einem Ensemble schraubenartig aufsteigender Blasen verdeutlicht.

An air bubble rising in resting water is imaged by a parallel projection in two perpendicular horizontal directions. Initially, these two projections are approximated by ellipses. In the next step, the bubble is modelled as a spheroid matching the ellipses. The resulting spheroid is suitable to analyse the orientation of the symmetry axis of the bubble during its propagation through the liquid phase. The capabilities of the method is illustrated on an ensemble of bubbles rising on a helical trajectory.]]></dc:description>

<dc:source><![CDATA[IAEA Specialists meeting "Irradiation effects and mitigation in Reactor Pressure Vessel", 28.05.2004, Gus Khrustalny, Russia]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[This paper provides a summary of Master Curve fracture toughness test results on small surveillance-type single- edge bend (SE(B)) and one-inch thick compact tension (1T-CT) specimens of the IAEA reference reactor pressure vessel (RPV) steel JRQ and other national RPV steels from numerous laboratories throughout the world. The JRQ test blocks distributed to the different laboratories were mainly from test plate 6JRQ.  The mean fracture toughness of the 6JRQ plate material generally can be described satisfactorily with the standard Master Curve method from ASTM E 1921-02.  The mean T0 values shows in accordance with previous investigations that a bias of around 10 K exists between the T0 values of CT and SE(B) specimen types so that CT specimens give higher T0. The analyses of both JRQ and national RPV steels confirm that the procedures specified in ASTM E 1921-02, as well as the SINTAP procedure, are generally valid and applicable for characterizing RPV type steels and even steels showing distributed inhomogeneity.]]></dc:description>

The results demonstrate the applicability of the normalization method for the J-R curve determination for a range of steels. The normalization method yields results, which deviate as much as 15 % from the values obtained with the unloading compliance method, and thus results of acceptable accuracy can e attained with this method.]]></dc:description>

<dc:title><![CDATA[What one learns from reactor pressure vessels of decommissioned nuclear power plants.]]></dc:title>
<dc:source><![CDATA[International Symposium FONTEVRAUD 7: Contribution of Materials Investigations to Improve the Safety And Performance of LWRs, 26.-30.09.2010, Avignon, France]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Nuclear power plant operators must demonstrate that the structural integrity of a nuclear reactor pressure vessel (RPV) is assured during routine operations and under postulated accident conditions. The aging of the RPV steels is monitored via surveillance programs. Radiation loading, metallurgical and environmental histories, however, can differ between surveillance and RPV materials. Therefore, the investigation of RPV material from decommissioned NPPs offers the unique opportunity to evaluate the real toughness response. Such an opportunity is now available through the investigation of RPV material from the decommissioned Greifswald NPP (WWER-440/V-230).
The Greifswald RPVs of 4 units represent different material conditions as follows:
	Irradiated (Unit 4),
	irradiated and recovery annealed (Units 2 and 3), and
	irradiated, recovery annealed and re-irradiated (Unit1).
The recovery annealing of the RPV was performed at a temperature of 475° for about 152 hours and included a region covering ±0.70 m above and below the core beltline welding seam.
Material samples of a diameter of 119 mm called trepans were extracted from the RPV walls. The research program is focused on the characterisation of the RPV steels (base and weld metal) across the thickness of the RPV wall.
This paper presents test results measured on the trepans of the beltline welding seam and base metal of the above mentioned conditions. The key part of the testing is focussed on the determination of the reference temperature T0 following the ASTM standard E1921-09 to determine the facture toughness, and how it degrades under neutron irradiation and is recovered by thermal annealing. Other than that the mentioned test results include Charpy-V and tensile test results. Following results have been determined:

<dc:description><![CDATA[Nuclear power plant operators must demonstrate that the structural integrity of a nuclear reactor pressure vessel (RPV) is assured during routine operations and under postulated accident conditions. The aging of the RPV steels is monitored via surveillance programs. Radiation loading, metallurgical and environmental histories, however, can differ between surveillance and RPV materials. Therefore, the investigation of RPV material from decommissioned NPPs offers the unique opportunity to evaluate the real toughness response. Such an opportunity is now available through the investigation of RPV material from the decommissioned Greifswald NPP (WWER-440/V-230).
The Greifswald RPVs of 4 units represent different material conditions as follows:
	Irradiated (Unit 4),
	irradiated and recovery annealed (Units 2 and 3), and
	irradiated, recovery annealed and re-irradiated (Unit1).
The recovery annealing of the RPV was performed at a temperature of 475° for about 152 hours and included a region covering ±0.70 m above and below the core beltline welding seam.
Material samples of a diameter of 119 mm called trepans were extracted from the RPV walls. The research program is focused on the characterisation of the RPV steels (base and weld metal) across the thickness of the RPV wall.
This paper presents test results measured on the trepans of the beltline welding seam and base metal of the above mentioned conditions. The key part of the testing is focussed on the determination of the reference temperature T0 following the ASTM standard E1921-09 to determine the facture toughness, and how it degrades under neutron irradiation and is recovered by thermal annealing. Other than that the mentioned test results include Charpy-V and tensile test results. Following results have been determined:
	The mitigation of the neutron embrittlement of the weld and base metal by recovery annealing could be confirmed.
	KJc values of the weld metals generally follow the course of the MC though with a large scatter.
	There is a large variation in the T0 values evaluated across the thickness of the multilayered welding seams.
	The T0 measured on TS oriented SE(B) specimens from different thickness locations of the welding seams strongly depends on the structure along the crack tip.
	It was demonstrated that T0 evaluated according to the SINTAP MC extension represents the brittle fraction of the data sets.
	A direct correlation between T0 and TT41J of the investigated weld metal is questionable due to the different thickness location of the crack tip and the notch root in pre-cracked SE(B) and the reconstituted Charpy-V specimens, respectively.
	A strong scatter of the fracture toughness KJc values of the recovery annealed base metal of Unit 1 is observed with clearly more than 2% of the values below the fracture toughness curve for 2% fracture probability. The application of the multimodal MC approach describes the temperature dependence of the  KJc values in a satisfactory manner.]]></dc:description>

The labeling of acyclic purine and pyrimidine nucleoside derivatives with fluorine-18 required for the HSV-1 tk imaging approach with Positron Emission Tomography (PET) 18 is described. The methoxytritylated and tosylated precursors were radiolabeled using a K[<SUP>18</SUP>F]F/kryptofix 2.2.2<SUP>TM</SUP> complex, followed by removal of the protecting groups under acidic conditions and HPLC purification. The radiochemical yields of the <SUP>18</SUP>F-tracers amount to 5 - 15 % (decay corrected) after a synthesis time of 85 - 95 min, the radiochemical purity was > 98 % with an average specific activity of 19 GBq/μmol at the end of synthesis.]]></dc:description>

<dc:description><![CDATA[The timing performance of various multigap resistive plate chambers (MRPCs) has been tested at the Rossendorf electron linac ELBE. Electrons with energies of 20-40 MeV have been used to mimic minimum ionizing hadrons to be detected in large-scale time-of-flight (TOF) detectors for future heavy-ion collision experiments. Referencing the TOF measurement to the accelerator radio frequency, no fast start detector was necessary. A typical time resolution (including contributions from front-end electronics) of about 70 ps has been achieved for individual strips of the multistrip-anode MRPCs. Rate dependencies and detection efficiencies have been investigated.]]></dc:description>

<dc:description><![CDATA[We present a nonresonant photoconductive terahertz detection antenna suitable for detection of both focused and unfocused terahertz radiations. Our system consists of a scalable terahertz emitter based on an interdigitated electrode structure and a detection antenna with similar electrode geometry. While the emitter is fabricated on semi-insulating GaAs we compare different ion-implanted GaAs-based detection antennas. We studied the dependence of the measured terahertz signal on the power and spot size of the gating laser pulse. In addition we compare the performance of our antenna with that of electro-optical sampling.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[The small punch test (SPT) is a suitable miniaturized test method to determine the actual and local material state in structural components under operating conditions. A combined experimental-numerical approach is presented to identify material parameters of plastic deformation and ductile damage behaviour from the SPT. Neural networks (NN) are generated and trained by finite element simulations to obtain the relation between a load displacement curve of the SPT and the matching material parameters. These parameters, identified from the SPT, are validated by reference values determined from smooth and notched tensile specimens. Next, the same parameters are used to simulate the ductile crack growth in fracture specimens by means of finite elements. This way, even fracture thoughness data J_Ic of the materials could be successfully predicted. These findings substantiate the feasibility to gain comprehensive material characteristics from the SPT and their transferibility to quantify the ductile failure of strucural components.]]></dc:description>

<dc:source><![CDATA[Uranium Mining and Hydrogeology IV, 11.-16.09.2005, Freiberg, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The ability of hydroxyapatite Ca10(OH)2(PO4)6 (HAP) to immobilize metal ions, particularly lanthanides and actinides, is well known. The long-term stability of this fixation is proven by natural analogue studies. Thus, HAP is a potential filling material in engineered barriers in abandoned mining areas as well as in the near-field of underground repositories for nuclear and toxic waste.
The interaction of U(VI) with HAP was studied in batch and unsaturated column experiments and by time-resolved laser-induced fluorescence spectroscopy (TRLFS). We investigated a seepage water from Schlema (Saxony) with a Uranium concentration of 10-5 M and a syn-thetic HAP packed in a matrix of purified quartz sand.
The batch sorption experiments show 100 % adsorption of UO22+. The break-through curves measured in the column experiments with continuous pulse injection yield a retardation factor Rf = 33.2 ± 1.5 compared to the conservative tracer tritiated water. This value corresponds to the strong adsorption behavior. An elution of the column with ten pore volumes of a uranium-free solution revealed a distinct tailing and a uranium recovery near unity. Thus, the sorption process proved reversible. The TRLFS measurements facilitate a differentiation of uranium bound to the HAP surfaces and to the quartz matrix. Furthermore, the surface speciation of uranium could be identified. Finally, a numerical model using the reactive transport code Crunch describes the transport behavior of uranium.]]></dc:description>

<dc:title><![CDATA[Surface Bond Structure of Uranium Adsorbed onto Mine Water Colloids]]></dc:title>
<dc:source><![CDATA[15th Users Meeting, 08.-11.02.2005, Grenoble, France]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The sorption complexes of uranium to colloidal ferrihydrite (Fh) were investigated by EXAFS and ATR FT-IR spectroscopy in mildly acidic solution (pH 5.5) in presence and in absence of atmospheric CO2. EXAFS has shown that sulfate, silicate, and carbonate are not involved as ligands bidentately bound onto the adsorbed U. Hence a new surface bond structure of U on hydrous ferric oxides is proposed which tightly fits the experimental EXAFS data. However, ATR FT-IR spectra suggest ternary uranyl carbonato surface complexes under these conditions open to the atmosphere. The conflicting spectroscopic results can be harmonized by proposing a monodentate linkage of the carbonate ligands.]]></dc:description>

<dc:description><![CDATA[The mining and processing of uranium during the last decades for nuclear fuel and nuclear weapon production resulted in generation of significant amounts of radioactive wastes. The mobility of this radionuclide is controlled by its interactions with ions, minerals and microorganisms present in nature. As a consequence of their small size and diverse metabolic activities, bacteria are able to interact intimately with uranium and other metal ions present in their environment. Assessment of the potential hazard posed by the presence of uranyl-bacterial complexes, as well as the development and application of accurate contaminant transport models, requires an understanding of the speciation of uranium associated with bacteria. This paper summarizes the effect of pH on the speciation of uranium bound by about fifteen bacterial strains isolated from uranium mining wastes. Microbiological methods in combination with Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy, Infrared (IR) spectroscopy, Transmission Electron Microscopy (TEM) and Energy Dispersive X-ray Spectroscopy (EDS) were applied. EXAFS analysis showed that the cells of the most bacterial strains studied precipitate U(VI) as m-autunite-like phase at pH 4.5, probably due to the release of the inorganic phosphate from the cells as result of the acidic phosphatase activity. However, at pH 2 uranium formed complexes with organically bound phosphates of the cell surface. At pH 3, both organic and inorganic phosphate uranyl species occur together. No structural differences of the uranium complexes formed by three types of Acidithiobacillus ferrooxidans at above mentioned pH values were found, indicating the implication of organic phosphate moieties in the complexation. However, in the case of B. sphaericus JG-A12 the uranium bonding was consistent with the formation of complexes with organic bound phosphate and carboxylate groups of the cell surface. We applied Iterative Target Test Factor Analysis to determine the speciation at different pH values quantitatively from the EXAFS spectra. Transmission electron microscopy and energy dispersive X-ray analysis revealed species and even strain-specific extracellular and/or intracellular uranium accumulations to varying degrees. Different hypothesis explaining the different coordination chemistry of uranium to bacteria in function of the pH of the uranium solution in terms of solubility of m-autunite and/or microbial activity will be discussed.]]></dc:description>

<dc:source><![CDATA[The 4-th International Conference "Safety Assurance of NPP with WWER", 23.-25.05.2005, Podolsk, Russia]]></dc:source>

<dc:description><![CDATA[The coolant mixing in PWR is an issue relevant for reactor safety, but of importance also for the optimisation of normal reactor operation. In the case of boron dilution accidents, the coolant mixing is the only effective mitigative mechanism against severe consequences of the accident. The degree of mixing determines the thermal and, therefore, mechanical load of the reactor pressure vessel wall. 

Within the European project FLOMIX-R, an unique experimental data base on coolant mixing in PWRs has been created. Experiments on coolant mixing have been performed at three European mixing test facilities representing different types of reactors. Additionally, slug mixing data from the FSUE EDO Gidropress VVER-1000 mock-up have been made available. Mixing under steady-state flow conditions, slug mixing during the start-up of the first main coolant pump and mixing of cold emergency core cooling (ECC) water have been investigated. Moreover, measurement data from a real VVER-440 reactor plant (NPP Paks in Hungary) have been made available. 

The measurement data base was used for the validation of computational fluid dynamics (CFD) codes. Calculations were performed for selected tests from the data base using the CFD codes CFX and FLUENT. For quality assurance in the CFD code validation, so-called Best Practice Guidelines (BPG) have been applied. The BPG require a minimization of numerical errors and solution errors by systematic grid and time step refinement and sensitivity tests on the impact of uncertainties in the boundary conditions, before the effect of different physical models can be assessed. The applicability of various turbulence modeling techniques was studied for transient and steady state flow. 

The paper gives on overview on the experimental data base and on first, preliminary conclusions from the CFD code validation.]]></dc:description>

<dc:description><![CDATA[The coolant mixing in PWR is an issue relevant for reactor safety, but of importance also for the optimisation of normal reactor operation. In the case of boron dilution accidents, the coolant mixing is the only effective mitigative mechanism against severe consequences of the accident. The degree of mixing determines the thermal and, therefore, mechanical load of the reactor pressure vessel wall. 

Within the European project FLOMIX-R, an unique experimental data base on coolant mixing in PWRs has been created. Experiments on coolant mixing have been performed at three European mixing test facilities representing different types of reactors. Additionally, slug mixing data from the FSUE EDO Gidropress VVER-1000 mock-up have been made available. Mixing under steady-state flow conditions, slug mixing during the start-up of the first main coolant pump and mixing of cold emergency core cooling (ECC) water have been investigated. Moreover, measurement data from a real VVER-440 reactor plant (NPP Paks in Hungary) have been made available. 

The measurement data base was used for the validation of computational fluid dynamics (CFD) codes. Calculations were performed for selected tests from the data base using the CFD codes CFX and FLUENT. For quality assurance in the CFD code validation, so-called Best Practice Guidelines (BPG) have been applied. The BPG require a minimization of numerical errors and solution errors by systematic grid and time step refinement and sensitivity tests on the impact of uncertainties in the boundary conditions, before the effect of different physical models can be assessed. The applicability of various turbulence modeling techniques was studied for transient and steady state flow. 

The paper gives on overview on the experimental data base and on first, preliminary conclusions from the CFD code validation.]]></dc:description>

<dc:source><![CDATA[Applied Physics Letters 87(2005), 043109]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In successive implantations of p- and/or n-dopants the implantation sequence may affect the ion range distributions. This is demonstrated for two consecutive implantations into the [001] channel direction: (i) 35 keV B  followed by 50 keV As and (ii) 50 keV As followed by 35 keV B. The defects formed in the first implantation cause enhanced dechanneling of the subsequently implanted ions and, therefore, influence the shape of the range distributions in the second implantation step. The experimental range profiles can be reproduced very well by atomistic computer simulations which take into account damage accumulation or dynamic annealing during a single implantation step as well as the influence of the defects formed by the preceding implantation steps.]]></dc:description>

<dc:description><![CDATA[The complex formation of neptunium(V) with 4-hydroxy-3-methoxybenzoic acid (vanillic acid) was studied by time-resolved laser-induced fluorescence spectroscopy with ultra-short laser pulses using the fluorescence properties of 4-hydroxy-3-methoxybenzoic acid. A 2:1 complex of neptunium(V) with 4-hydroxy-3-methoxybenzoic acid was found. The stability constant of this complex was determined to be log β210 = 7.33 ± 0.10 at an ionic strength of 0.1 mol/l (NaClO4) and at 21 °C. The determination of the stability constant required an investigation of the excited-state proton transfer of 4-hydroxy-3-methoxybenzoic acid over the whole pH range. It was realized that 4-hydroxy-3-methoxybenzoic acid undergoes excited-state reactions only at pH values below 5. At pH values above 5 stability constants can be determined without kinetic calculation of the proton transfer.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Endocrine-disrupting compounds (EDC´s) constitute a wide group of environmental pollutants that causes severe effects on the people and wild life. Actually, considerable interests have been focused on quantification methods for analytical tracing of chemical substances in drinking water, as in food industry, and medical diagnostic. 
A sensor concept for estrogen detection in waterish solutions by Silicon based light emitters (MOSLED) was developed. This concept is based on direct fluorescence analysis and consists of a certain arrangement of the bio- components and their fabrication methods as well as the measurement protocol. 
The functionalization of the SiO2 surface of the MOSLED was realized by means of the new developed SSC (Spraying Spin Coating) method. The chemical precursors of this method are organofunctional silane groups with three different functional groups, namely the amino-, carboxyl-, and thiolgroups. These results have been compared with those of the literature. The optimization of the SSC-method was analyzed by means of standard surface science techniques like FTIR-, Raman-, and XPS-spectroscopy. The surface roughness was applied by using AFM-spectroscopy, which showed a smooth surface by the samples treated with the SSC-method. 
In order to immobilize the hER(alpha) receptor at the surface, the receptor was bound to the molecular shell of the QDot655 dye and finally adsorbed to the silanized SiO2 surfaces. The fraction of the immobilized hER(alpha) receptors was controlled via Photoluminescence-measurements.
The whole concept of the sensor was tested at two water samples containing estrogen in different concentrations.]]></dc:description>

<dc:source><![CDATA[Inorganic Chemistry 49(2010), 6381-6383]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[This paper describes, for the first time, a simple method for the synthesis of uranyl aluminate (URAL) nanoparticles. URAL was prepared by U(VI) hydrolytic precipitation with ammonia at pH = 11 in the presence of mesoporous alumina MSU-X under 20 kHz of sonication followed by annealing of the obtained solids at 800 C. TEM, XAFS, powder XRD, and 27Al MAS NMR studies revealed that the speciation of uranium in this system strongly depends on uranium concentration. The sample with 5 wt % of uranium yields air-stable nanoparticles (∼5 nm) of URAL. Presumably, UO2 2þ cations in this compound are coordinated with bidentate AlO2 - groups. The increase of uranium concentration to 30 wt % causes mostly formation of U3O8 fine particles (∼50 nm) and small amounts of URAL.]]></dc:description>

<dc:description><![CDATA[Multiferroic rare-earth manganites have attracted much attention because of the coexistence of ferroelectric and magnetic orders. Using THz-range FEL- and BWO-based electron spin resonance (ESR) spectroscopy techniques, the frequency-field dependence of magnetic excitations in the hexagonal multiferroic YMnO<sub>3</sub> in the antiferromagnetically (AFM) ordered phase has been studied. A slope of the frequency-field dependences of AFM resonance modes, ~ 0.5 cm<sup>−1</sup>/T, is explaned in terms of the triangular AFM model. A gap in the excitation spectrum, ~ 42 cm−1, was observed directly. A fine structure of AFM resonance absorption observed by as is a clear signature of a finite interaction between the neighboring Mn<sup>3+</sup> layers. The interplane exchange interactions constants, J<sub>1</sub> = -510 mK and J<sub>2</sub> = -350 mK, have been estimated.]]></dc:description>

<dc:title><![CDATA[Krein space related physics: PT-symmetric Quantum Mechanics, MHD α²-dynamos, planar Couette flows, ...]]></dc:title>
<dc:source><![CDATA[3rd International Workshop on Pseudo-Hermitian Hamiltonians in Quantum Physics, 20.-22.06.2005, Istanbul, Turkey]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Operator theoretic structures are discussed which underlie PT-symmetric Quantum Mechanics (PTSQM), the spherically symmetric α²-dynamo of magnetohydrodynamics (MHD) and the plane Couette flow of hydrodynamics (described by the Squire equation). Mathematically, the three types of models are closely related as spectral problems in Krein spaces − Hilbert spaces with an indefinite metric structure.
In contrast to the purely real spectrum of self-adjoint operators in "usual" Hilbert spaces, the spectrum of self-adjoint operators in Krein spaces consists, in general, of two types of spectral sectors: sectors with purely real eigenvalues and other sectors with pairwise complex conjugate eigenvalues. Transitions between different sectors occur at exceptional points of square root branching type. Knowing the boundaries of the sectors in parameter space one would know, e.g., the boundaries of the physical sectors of PTSQM (with exact/unbroken PT-symmetry) or of the oscillatory regimes of α²-dynamos.
The underlying Krein space related structure of the different physical setups indicates a possible fruitful interplay of these models in handling their technical and conceptual aspects on a unified footing. We make some aspects of such an interplay explicit and demonstrate its usefulness on the example of a PT-symmetric interpolation model and the Squire equation of hydrodynamics. This allows us to gain a deeper insight into the specifics of the Herbst limit.

The talk is based on material from math-ph/0501069 (which is to appear in J. Math. Phys.) and extends it.]]></dc:description>

<dc:source><![CDATA[4th Workshop on Semiconductor Nanodevices and Nanostructured Materials (NANOSEMIMAT-4), 09.-13.03.2005, Sao Pedro, SP, Brazil]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Recently remarkable progress has occurred in the variety and efficiency of silicon based light emitters, based on Si pn junctions, Si MOS structures doped with rare earth elements, or containing Si nanoclusters. I will present our work in some of these areas. 

We have fabricated Si light emitting diodes (LED) by high-dose boron implantation into n-type Si. The free-exciton electroluminescence (EL) increases with temperature, reaching wall-plug efficiencies of more than 0.1% at room temperature. A model which is based on excitons localized near nanoscale boron doping spikes can explain the EL dependence on current and temperature. We have integrated such structures into a microcavity with a buried metallic CoSi2 bottom mirror and a Si/SiO2 Bragg mirror on top. This resonant-cavity LED exhibits significant spectral narrowing, consistent with the quality of the cavity. 

We also have fabricated light emitting Si MOS structures which were implanted with various rare-earth elements, from the well known Er3+ emitting at the telecom wavelength of 1.54 microns, to Gd3+, which emits in the deep UV at 316 nm. This is, to our knowledge, the first Si based UV light emitter, with many potential applications in areas such as bio-sensing.]]></dc:description>

<dc:title><![CDATA[Investigation of the creation of Fe nanoparticles in MgO by ion beam synthesis]]></dc:title>
<dc:source><![CDATA[International Conference on the Applications of the Mössbauer Effect, 05.-09.09.2005, Montpellier, France]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Recently, the investigation of metallic nanoparticles embedded in dielectric oxides has become a topic in magnetic data storage development. Especially the creation of high density data storage devices due to ion beam synthesis of magnetically, highly anisotropic FePt nanoparticles in sapphire yielded promising results. On the other hand, pure Fe-nanoparticles have been created in sapphire, Y-stabilized ZrO2 or MgO. The motivation for the latter includes the search for magneto-optically active surfaces as well as pronounced magnetoresistance.
For doping MgO single crystals with Fe, ion implantation is a promising technique. First extensive studies were performed by Perez et al. who investigated the annealing behaviour of samples implanted with different doses of 57Fe at different energies with conversion electron Mössbauer spectroscopy (CEMS) [1]. They obtained up to 20 % of the implanted iron atoms  in a-Fe precipitates while the remaining Fe-atoms were found to be in different Fe2+ and Fe3+ charge states.

In this paper, we propose a method for the creation of large fractions of a-Fe nanoparticles (up to 60%).  MgO(001) single crystals were implanted with of 6x1016 cm-2  ions of the Mössbauer isotope  57Fe at 100 keV. The  implantation temperature was varied from room temperature up to 800 °C. Moreover, post annealing was investigated. Samples were characterized by CEMS, RBS, TEM and XRD. We found that the temperature during the implantation plays the important role for the formation of the Fe0 state while post annealing results in the preferential formation of Fe oxidation states, mainly Fe3+ states. The largest fraction of iron with  Fe0 state was obtained at implantation temperatures between 600 and 800 °C.

<dc:description><![CDATA[Experiments were done at the TOPFLOW facility of the Forschungszentrum Dresden-Rossendorf to establish a CFD-grade database on the condensation of steam bubbles injected into sub-cooled upwards vertical pipe flow. Bubble size distributions are important, since the condensation rate is proportional to the interfacial area density. To develop and validate closure models for CFD codes experimental data with high resolution in space and time are required. The steam was injected via orifices in the pipe wall located at different distances from measuring plane. 1 mm and 4 mm injection orifices are used to vary the initial bubble size distribution. The variation of the distance between the location of the gas injection and the measuring plane allows investigating the evolution of the flow along the pipe. Pressure, steam and water flow rates and the sub-cooling were also varied. Measurements are done using wire-mesh sensors and thermocouples. Data on averaged void fraction, radial gas volume fraction profiles, profiles of the gas velocity and bubble size distributions in dependency of the L/D ratio are presented.]]></dc:description>

<dc:description><![CDATA[Es werden neue Messergebnisse zur Fluoreszenz vom Americum(III) vorgestellt. Die Fluoreszenzzerfallszeit liegt im Nanosekundenbereich. Aufgrund der Analogie zum Curium(III) sollte auch beim Americum die Anzahl der Wassermoleküle in der Solvathülle die über die fluoreszenzzerfallskonstante ermittelt werden können. Es erschien aufgrund der Datenlage (Fluoreszenzzerfallszeit) ratsam, frühere Untersuchungen von Kimura zu wiederholen. Vorgestellt werden außerdem Untersuchungen zur Komplexbildung von Neptunium mit Vanillinsäure und von Kupfer(II) mit verschiedenen Dendrimeren.]]></dc:description>

<dc:description><![CDATA[The light meson dilepton identification in the HADES detection system is based on an invariant mass reconstruction of their decay into e<sup>+</sup>e<sup>-</sup> pairs. Methods of the dilepton signal reconstruction in the HADES spectrometer and preliminary dilepton spectra for C+C reactions at 2 AGeV are presented in this paper. In the signal reconstruction particularly important is the reduction of the huge combinatorial background arising from wrong combinations of electrons and positrons into un-like sign pairs. A purity of the dilepton signal is determined by using GEANT simulation with the full HADES geometry and a realistic detector response.]]></dc:description>

<dc:description><![CDATA[Risk assessments of actinide-contaminated soils and sediments require detailed knowledge of actinide speciation and its long-term kinetics. Former Saxonian mine tailings, which have been covered but else left undisturbed, are ideally suited to study changes in uranium speciation over timescales of decades. We investigated the major uranium species in two samples from buried mine tailings using a combination of Synchrotron-based microfocus-techniques (μ-XRF, μ-XRD with micrometer resolution), bulk EXAFS spectroscopy, and chemical extractions.
In sample F1 (5 m depth, oxic, pH 8, U=440 mg/kg, high Ca, S, Pb, Cu, Zn concentrations), uranium is diffusely distributed among aggregates of layer silicates (muscovite, illite and kaolinite). The chemical extractions and EXAFS results confirm that uranium is sorbed to these minerals, but is not incorporated into their crystal structure. Sorption is also in line with the high pH and low carbonate concentrations in pore water. In sample F3 (12 m depth, oxic, pH 4, U=430 mg/kg), the combination of μ-XRF and μ-XRD enabled us to identify several U(IV) and U(VI) containing minerals like coffinite, uraninite, uranyl hydroxide, and vanuralite. Only a minor part of U is sorbed to layer silicates as confirmed by chemical extractions and EXAFS spectroscopy.
At smaller depth (F1, 5 m), sulfuric acid from the ore extraction procedure was completely neutralized by the construction waste used as cover material, resulting in precipitation of jarosite and gypsum. Even 30 years after the ore extraction, uranium remains highly soluble. At greater depth (F3, 12 m), the low pH from ore extraction was conserved. The presence of U(IV) minerals suggest either precipitation of secondary (IV) minerals due to microbial redox activity, or incomplete dissolution of primary (IV) minerals due to ore processing inefficiency of these older sediments. The U(IV) minerals were recalcitrant during chemical extractions, suggesting low uranium solubility even at oxic redox conditions. The results demonstrate a very high variability of uranium speciation and hence potential mobility, which seems to depend on geochemical parameters and site history, but shows little influence of time.]]></dc:description>

<dc:source><![CDATA[Japan-Germany Colloquium 2005: Semiconductor Physics and Technology, 14.-16.02.2005, Dresden, Deutschland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[I will discuss two recent advances related to semiconductor light sources in the infrared and THz regions. One example is a quantum cascade laser operating at a wavelength shorter than 4 microns above room temperature with high peak power. It is based on strained InGaAs/InAlAs on InP, with the addition of high barriers of pure AlAs for better confinement and strain compensation. In a novel few-cycle THz emitter we try to combine the advantages of the high electric bias field in photoconductive antennas with a large active area. This is achieved with an interdigitated electrode structure, partially covered in order to mask one field polarity. As a result no destructive interference of the emitted THz wave occurs, which allows upscaling of the device area.]]></dc:description>

<dc:description><![CDATA[The strain Bacillus sphaericus JG-A12 was isolated from a uranium mining waste pile near the town of Johanngeorgenstadt, Germany. The cells of this strain are capable of selective and reversible accumulation of U, Cu, Pb, Al, and  Cd from the U waste waters. It was demonstrated that this strain is enveloped by a surface layer protein (S-layer) which differs significantly in its primary structure from the other B. sphaericus S-layers studied up to date. The highly regular structure of the S-layers with many pores of identical size offers good binding sites for different kind of molecules and also nucleation sites for formation of metal nanoclusters like Pd, for example. In this study we demonstrate that the cells of B. sphaericus JG-A12 and their purified and recrystallized S-layer are capable to bind effectively Au(III) from salt solutions. Moreover, in the presence of reducing agents such as molecular H2, Au(III) is reduced to metallic nanoclusters. Reduced gold nanoclusters were regularly distributed and sized according to the pores of the protein lattice. The metallic nature of the clusters was confirmed by different techniques such as EXAFS, XANES, UV-Vis spectroscopy and by X-ray powder diffraction. The size of the gold nanoparticles was estimated to be about 10 Å. Changes in functional groups in the cells and S-layer due to gold binding were observed by FT-IR microscopy. The cellular localization of the deposited Au(III) and of the gold nanoclusters was defined using transmission electron microscopy (TEM) and environmental scanning electron microscopy (ESEM). The results demonstrated that B. sphaericus JG-A12 might be used to prepare gold nanoparticles that can be tailor-made for particular applications.]]></dc:description>

<dc:title><![CDATA[Magnetic field control of the mould filling process of aluminium investment casting]]></dc:title>
<dc:source><![CDATA[Sino-German Workshop on EPM, 11.-13.10.2004, Shanghai, China]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[The mould filling process of aluminum investment casting consists basically of the flow in a U-bend showing a high pouring velocity at the beginning and decreasing velocity values during the course of the process. The high velocities during the starting phase are supposed to cause distinct problems like bubble or inclusion entrapment. Several types of filters are already in use for the purpose of inclusion filtering but velocity reduction, too.
We present results on the design and application of a DC magnetic field to control the pouring velocity. Numerical calculations were performed to simulate the filling process and the effect of the magnetic field. The free surface problem which occurs in the riser of the casting unit was taken into account by a Volume-of-Fluids Method. 3d transient calculations using the commercial finite- element code FIDAP (FLUENT Inc.) were carried out for a simplified model system as well as for the real aluminum casting unit. The term for the electromagnetic force was implemented into the code via a user defined subroutine, and an additional equation for the electrical potential was solved. End effects due to the limited size of the magnet poles were taken into account. In that way, results from three-dimensional transient simulations of the filling process were obtained.
Parallel to the simulations model experiments have been performed using the low melting eutectic InGaSn. The casting unit was modelled by a plexiglas model. The ultrasonic Doppler velocimetry was applied to carry out detailed velocity measurements in the model. Such measurements delivered the basis to validate the numerical calculations. A comparison between numerical and experimental results showed an excellent agreement, allowing scaling up the simulations to the realistic aluminium casting process. 
Real tests have been performed at an industrial investment caster with molten aluminium. The primary action of the magnetic field, i.e. the reduction of the velocity peaks at the beginning of the process, was clearly shown. In a second set of experiments the amplitude of the DC field was tuned during the process. At the beginning the maximum braking force was applied, whereas the field strength was reduced with increasing fluid level in the casting unit. In this regime, a clear reduction of the peak velocities is obtained without a significant prolongation of the overall filling time.]]></dc:description>

<dc:description><![CDATA[For the investigation of air/water stratified flow, a horizontal channel with rectangular cross-section was build at Forschungszentrum Rossendorf. The channel allows the investigation of air/water co- and counter-current flows under atmospheric pressure, especially the slug behaviour.
Optical measurements were performed with a high-speed video camera, and were complemented by simultaneous dynamic pressure measurements. Further, an interface capture technique was developed and possible applications (e.g. plot of the time dependent water level in a cross-section, recognition of the slug position) presented.]]></dc:description>

<dc:description><![CDATA[Vanadium doped ZnO thin films (Zn1−xVxO, where x=0.05 or x=0.13) were grown on c-cut sapphire substrates using pulsed laser deposition technique. Their structure and magnetic properties were examined in relation to the doping concentration. All deposited films were highly oriented along the c-axis and exhibited ferromagnetic behavior with a Curie temperature up to 300 K. The crystal structure was found to be better for layers with lower vanadium concentration. The films had a porous fine-grained microstructure and a column-like character as the V concentration was reduced. A weak dependence of magnetization on temperature was observed. The saturation magnetization was found to be strongly dependent on the crystal structure, grain size and V-ion concentration.]]></dc:description>

<dc:source><![CDATA[Experimental Thermal and Fluid Science 35(2011)1, 11-19]]></dc:source>
<dc:date>2011</dc:date>
<dc:description><![CDATA[In this article, dispersed flow of viscous oil and water is investigated. The experimental work was performed in a 26.2-mm-i.d. 12-m-long horizontal glass pipe using water and oil (viscosity of 100 mPa.s and density of 860 kg/m<sup>3</sup>) as test fluids. High-speed video recording and a new wire mesh sensor based on capacitance (permittivity) measurements were used to characterize the flow. Furthermore, holdup data were obtained using quick-closing-valves technique (QCV). An interesting finding was the oil-water slip ratio greater than one for dispersed flow at high Reynolds number. Chordal phase fraction distribution diagrams and images of the holdup distribution over the pipe cross-section obtained via wire-mesh sensor indicated a significant amount of water near to the pipe wall for the three different dispersed flow patterns identified in this study: Oil-in-water Homogeneous Dispersion (o/w H), Oil-in-water Non-homogeneous Dispersion (o/w NH) and Dual continuous (Do/w & Dw/o). The phase slip might be explained by the existence of a water film surrounding the homogeneous mixture of oil in water in a hidrofilic-oilfobic pipe.]]></dc:description>

<dc:description><![CDATA[In nondestructive testing (NDT) of microelectronic components many applications using X-ray radiography are well established. This method is based on the attenuation of radiation intensities of x-rays transmitting an object. Computer tomography (CT), however, is a visualization method which is based on reconstructing three-dimensional models from several two-dimensional X-ray projections of the object. It is only recently used for NDT because it is more expensive and time consuming than conventional X-ray imaging. Nevertheless, there are applications where simple radiography provides only poor results because of superimposed object layers. This article discusses NDT specific problems of CT such as beam hardening and shows some microelectronic applications benefiting from CT as well as examples where modifications of the standard CT procedure are necessary to gain depth information about the object. This so called limited angle tomography reaches a higher image resolution than CT when flat modules are tested.]]></dc:description>

<dc:description><![CDATA[In nondestructive testing (NDT) of microelectronic components many applications using X-ray radiography are well established. This method is based on the attenuation of radiation intensities of x-rays transmitting an object. Computer tomography (CT), however, is a visualization method which is based on reconstructing three-dimensional models from several two-dimensional X-ray projections of the object. It is only recently used for NDT because it is more expensive and time consuming than conventional X-ray imaging. Nevertheless, there are applications where simple radiography provides only poor results because of superimposed object layers. This article discusses NDT specific problems of CT such as beam hardening and shows some microelectronic applications benefiting from CT as well as examples where modifications of the standard CT procedure are necessary to gain depth information about the object. This so called limited angle tomography reaches a higher image resolution than CT when flat modules are tested.]]></dc:description>

<dc:description><![CDATA[Uranium is of great importance for the Morsleben radioactive waste disposal site. Its retention by both backfilling materials and the overlying rock was determined in batch sorption experiments over a period of 400 days. There, the solution simulated the brines typical for this site. The observed retention at the backfilling and overlying rock materials was in the regions of 95.8 to 100% and 92.7 to 98.1%, respectively. The solubility of solid U<sub>3</sub>O<sub>8</sub> in these brines was determined to be between 5*10<sup>-9</sup> and 9*10<sup>-6</sup> mol/L uranium.

<dc:description><![CDATA[In preparation for thermochromatographic adsorption studies of Lr in metal columns at temperatures up to 2000 K we investigated the metal adsorption of Cm and Bk. Cm was chosen to model Lr as a trivalent metal and Bk as a trivalent actinide having a (divalent) fn+1s2 ground state configuration. 250Bk electroplated on tantalum and 248Bk/246Cm implanted in zirconium foils were used as actinide sources. To carry out an adsorption experiment the actinide sources were placed at the starting position of the thermochromatographic columns and hold for 30 min at 1850 K. Standard enthalpies of adsorption were calculated from the experimental results and compared with calculations using a semi-empirical method. Based on these results, the capability of the method for studying electronic and metallic state properties of the heaviest actinides up to Lr is discussed.  ]]></dc:description>

<dc:description><![CDATA[The coolant mixing is of relevance for two classes of accident scenarios  boron dilution and cold-water transients. Experimental investigations and numerical simulations of coolant mixing in the downcomer and the lower plenum of PWRs was the topic of the EU-Project FLOMIX-R. The results of the project showed, that coolant mixing has a high relevance for nuclear safety. The coolant mixing is the only inherent mechanism, which reduces risks of power excursions. For the investigation of the relevant mixing phenomena, the Rossendorf test facility ROCOM has been used. ROCOM is a 1:5 scaled  Plexiglas model of the PWR Konvoi allowing conductivity measurements by wire mesh sensors and velocity measurements by the LDA technique. Series of experiments were performed at ROCOM to study the mixing of a slug of lower borated water during the start-up of the first main circulation pump.

The CFD calculations were carried out with the code CFX-5. A complex hybrid mesh with the size of 2 million nodes and 4 million elements was used. The turbulence was modeled with the SST model.  

Due to the strong momentum insertion during the pump start-up, a dominating horizontal component of the flow was observed near the inlet nozzle leading to a circumferential flow around the core barrel.  Therefore, the injected slug is distributed into two main jets, and the maximum of the tracer concentration at the core inlet appears firstly at the location opposite to the loop where the tracer was injected. For turbulent flows the CFD-Code CFX-5 was validated for turbulent, momentum driven mixing. A better description of the mixing processes inside the RPV is the basis of a more realistic safety assessment concerning boron dilution scenarios.]]></dc:description>

<dc:description><![CDATA[The coolant mixing is of relevance for two classes of accident scenarios  boron dilution and cold-water transients. Experimental investigations and numerical simulations of coolant mixing in the downcomer and the lower plenum of PWRs was the topic of the EU-Project FLOMIX-R. The results of the project showed, that coolant mixing has a high relevance for nuclear safety. The coolant mixing is the only inherent mechanism, which reduces risks of power excursions. For the investigation of the relevant mixing phenomena, the Rossendorf test facility ROCOM has been used. ROCOM is a 1:5 scaled  Plexiglas model of the PWR Konvoi allowing conductivity measurements by wire mesh sensors and velocity measurements by the LDA technique. Series of experiments were performed at ROCOM to study the mixing of a slug of lower borated water during the start-up of the first main circulation pump.

The CFD calculations were carried out with the code CFX-5. A complex hybrid mesh with the size of 2 million nodes and 4 million elements was used. The turbulence was modeled with the SST model.  

Due to the strong momentum insertion during the pump start-up, a dominating horizontal component of the flow was observed near the inlet nozzle leading to a circumferential flow around the core barrel.  Therefore, the injected slug is distributed into two main jets, and the maximum of the tracer concentration at the core inlet appears firstly at the location opposite to the loop where the tracer was injected. For turbulent flows the CFD-Code CFX-5 was validated for turbulent, momentum driven mixing. A better description of the mixing processes inside the RPV is the basis of a more realistic safety assessment concerning boron dilution scenarios.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[We introduce a new method to noninvasively and continuously measure the swelling process of the nasal mucosa. Thereby we use light of different wavelengths in the near infrared range which is transilluminated through the nasal tissue and whose extinction is recorded as a function of time. From the temporal and spectral extinction data we are able to extract characteristic parameters that describe the swelling process quantitatively by means of a regression type parameter estimation algorithm. Furthermore, we show the capability of the method to quantify hemoglobin saturation in the surplus blood volume and introduce a bilateral measurement approach that allows us to examine the swelling process in both nasal cavities simultaneously. The method has been applied to the nasal allergen provocation test and verified on a limited number of volunteers.]]></dc:description>

<dc:source><![CDATA[342. WE-Heraeus Seminar "Science and Technology of Inorganic Nanowires", 13.-16.02.2005, Bad Honnef, Deutschland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In this contribution, results of predictive atomistic computer simulations are presented which describe the ion beam synthesis of single-crystalline CoSi2 nanowires (NWs) embedded in Si. In order to simulate the Co implantation, the binary collision codes TRIDYN and TRIM were adapted to the particular experimental situation of a finely focused Co ion beam of a few tens of nanometers in width. The resulting 3D implantation profile serves as input for a kinetic lattice Monte-Carlo code by means of which nucleation and growth of CoSi2 precipitates and their coalescence into a CoSi2 NW are described.
Due to the systems tendency towards a reduction of interfacial free energy (Rayleigh instability), it will be demonstrated that the orientation of the Co implantation profile to the Si matrix influences the stability of the synthesized CoSi2 NW. Since the system energetically favors the CoSi2(111)/Si(111) interface, faceting forces occur if the Co implantation profile is not aligned with the Si-[011] direction. Thus, intentional misalignment is a possible way to a controlled decay of the NW into a chain of monodisperse and equidistant nanoclusters which is applicable as plasmon waveguide.]]></dc:description>

<dc:description><![CDATA[We report on the first analysis of directed and elliptic flow with the new method of Lee-Yang zeroes. Experimental data are presented for Ru+Ru reactions at 1.69A GeV measured with the FOPI detector at SIS/GSI. The results obtained with several methods, based on the event-plane reconstruction, on Lee-Yang zeroes, and on multi-particle cumulants (up th 5th order) applied for the first time at SIS energies, are compared. They show conclusive evidence that azimuthal correlations between nucleons and composite particles at this energy are largely dominated by anisotropic flow.]]></dc:description>

<dc:title><![CDATA[In-situ x-ray diffraction studies concerning the influence of Al concentration on the texture development during sputter deposition of Ti-Al-N thin films]]></dc:title>
<dc:source><![CDATA[Journal of Vacuum Science & Technology A 23(2005)5, 1384-1391]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In-situ x-ray diffraction was employed during the growth of thin Ti<SUB>1-x</SUB>Al<SUB>x</SUB>N films, using a deposition chamber installed at a synchrotron radiation beamline. The films were deposited by reactive co-sputtering from Ti and Al targets. At constant x ~ 0.06, substrate temperature, bias voltage, and nitrogen partial pressure, and thus growth rate, was varied. Further, x was systematically varied from 0 to 0.73 while keeping all the other parameters constant. x < 0.15 and high deposition rates of ~ 1 Å/s lead to the typical crossover behavior between initial (001) and final (111) off-plane preferred orientation. Reducing the deposition rate to < 0.5 Å/s leads to a reversed behavior with a clear (001) preferred orientation above a film thickness of 600 Å which is essentially independent of the substrate temperature. Keeping the deposition rate low, the (111) preferred orientation can be recovered for x > 0.15, which can be explained by the higher adatom mobility of Al compared to Ti in the presence of atomic nitrogen. Increasing x towards the AlN segregation threshold at x ~ 0.60 leads to hard nano-composite nc-TiAlN/AlN structures, and x > 0.73 finally leads to dominant AlN with an a-axis off-plane texture.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[A general but simple method is proposed to eliminate the quantum fluctuations generated by selected one-body operators in the excitation spectrum of a discrete random phase approximation (RPA) Hamiltonian. This method provides an outstanding tool for the removal of the contaminating spurious effects originated from symetry violations. It can be also applied as a mode filter for analyzing RPA response functions.]]></dc:description>

<dc:description><![CDATA[EDXRF analysis with subsequent multivariate data analysis proves useful for the determination of the authenticity of iridescent glass artifacts. Thus, clusters of the glass groups investigated were formed which can be associated with the glass manufacturers. By means of ion beam analysis with the external proton beam the producing technology of iridescent glass objects of the Art Nouveau glass manufacturer Loetz/Austria with so-called Papillon pattern was characterised in a non-destructive way. Due to the simultaneous application of PIXE and RBS the glass structure including a sequence of glass layers covered with a SnO2-layer of approximately 50 nm thickness on the surface could be described.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[Structural modifications of solid Si (0 0 1) targets exposed to the XUV TESLA free lectron laser radiation were studied. The samples were irradiated with the photon energy centered at 14 eV, in short pulses of only 80 fs and of peak power up to 1 GW. The FEL beam was focused on sample surfaces to microspots of size 10100m. The energy density in the spots varied from below the ablation threshold up to far above this threshold. The structural modifications induced with the irradiation were studied by AFM, Nomarski contrast microscopy and by X-ray diffraction methods. A variety of morphological structures created in the damaged areas was found. The maps of the X-ray diffracted intensity distribution recorded around chosen spots on the Si surface made it possible to probe the damage distribution range around the spots. The observed features are related to the FEL irradiation fluencies applied.]]></dc:description>

<dc:description><![CDATA[Combined external Ion Beam Analysis (IBA) measurements, consisting of Proton Induced X-ray EmissionProton Induced Gamma-ray EmissionRutherford Back-Scattering (PIXE-PIGE-RBS) have been performed on several obsidian fragments with archaeological significance at the Rossendorf tandem accelerator using a 3.85 MeV proton beam. A comparison was made between these external IBA results and the ones previously obtained on the same obsidian samples using Laser AblationInductively Coupled PlasmaMass Spectrometry (LA-ICP-MS). The purpose of the study was to assess the potentiality of external IBA for provenance studies on archaeological obsidian, especially as a non-destructive alternative to the LA-ICP-MS method. As an example, the source attribution of an archaeological obsidian fragment from Transylvania to Tokay Mountains/Slovakian range flow is discussed.]]></dc:description>

<dc:description><![CDATA[This paper reports about the DYN1D-MSR code development and dynamics studies of the molten salt reactors (MSR)  one of the Generation IV International Forum concepts. In this forum the graphite-moderated channel type MSR based on the previous Oak Ridge National Laboratory research is considered.
The liquid molten salt serves as a fuel and coolant, simultaneously and causes two physical peculiarities: the fission energy is released predominantly directly into the coolant and the delayed neutrons precursors are drifted by the fuel flow. The drift causes the spread of delayed neutrons distribution to the non-core parts of primary circuit and it can lead to a reactivity loss or gain in the case of fuel flow acceleration or deceleration, respectively. Therefore, specific 3D tool based on in house code DYN3D was developed in FZR. The code DYN3D-MSR is based on the solution of two-group neutron diffusion equation by the help of a nodal expansion method and it includes models of delayed neutrons drift and specific MSR heat release distribution.
In this paper the development and verification of 1D version DYN1D-MSR of the code is described. The code has been validated with the experimental data gained from the molten salt reactor experiment performed in the Oak Ridge and after the validation it was applied to several typical transients (overcooling of fuel at the core inlet, reactivity insertion, and the fuel pump trip).]]></dc:description>

<dc:title><![CDATA[Turbulent dispersion of bubbles in poly-dispersed gas-liquid flows in a vertical pipe]]></dc:title>
<dc:source><![CDATA[13th International Conference on Nuclear Engineering, 15.-20.05.2005, Beijing, China]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The turbulence of the liquid phase has a signi cant dispersion e ect on the migration of bubbles in a vertical  ow. Based on a double averaging approach and by adopting the Favre averaged velocity, a generalized model, called the Favre Averaged Drag (FAD) Model, was developed for the turbulent dispersion force for Eulerian simulations of multiphase  ows [Burns et al., 2004]. The model formulation was originally derived from the instant Eulerian model equations as a result of the correlation between the inter phase drag and the volume fractions. In this work, a new model derivation from the two-way coupled Lagrangian formulation is provided. This derivation makes the sense of the double averaging approach straightforward. Moreover, the new derivation provides a theoretical foundation for applying the FAD model to the Lagrangian solver, which will signi cantly increase the computational e ciency. We also provide validation and evaluation for this model by numerical and experimental investigations of bubbly  ows in a vertical pipe. The experimental data were obtained by using the wire-mesh sensor technique. The computations were carried out by applying poly-dispersed models. The emphasis is to examine the model applicability under various  ow conditions including bubbly  ows with a wall peak and a core peak of the gas volume fraction,  ows in the transition region between them, and in the  nely dispersed  ow regime. The e ect of the drag force model on the turbulent dispersion force was also examined.]]></dc:description>

<dc:description><![CDATA[Gefährlich, riskant, umweltschädigend, gesundheitsschädlich, unverantwortbar, unwirtschaftlich, unsozial, nicht nachhaltig - das sind Adjektive, mit der die Nutzung der Kernenergie zur Stromversorgung häufig belegt wird. Tatsächlich tragen die Kernkraftwerke jedoch stabil zur kostengünstigen Stromversorgung bei. In Deutschland haben sie einen Anteil von 30 %, in einigen Ländern mehr. Unter dem Eindruck spürbar anwachsender Brennstoffpreise bei den fossilen Energieträgern und immer deutlicher werdender Folgen der Klimaveränderungen mehren sich die Stimmen, die eine Renaissance der Kernenergie für notwendig halten. In einer solchen Situation ist es wichtig, die Potenzen der Energiegewinnung durch Kernspaltung zu kennen und die wichtigsten Behauptungen der Kernenergiegegner kritisch zu hinterfragen. Speziell für Deutschland wird ein Blick auf die gängigen Konzeptionen zur Energiestrategie der nächsten 50 Jahre geworfen. Letztendlich wird der Schluss gezogen, dass langfristig ein Umsteuern auf einen Mix aus nuklearen und regenerativen Energiequellen erfolgen muss, um zu einer nachhaltigen und ökonomisch, sozial und ökologisch vertretbaren Energieversorgung zu gelangen.]]></dc:description>

<dc:description><![CDATA[Silizium ist zwar die Basis für nahezu die gesamte Mikroelektronik, die Integration mit optischer Funktionalität ist jedoch nur eingeschränkt möglich, da Silizium als indirekter Halbleiter ein schlechter Lichtemitter ist. Andere optoelektronische Komponenten, wie Dektektoren, Modulatoren oder Wellenleiter können aus Silizium hergestellt werden, ein Siliziumlaser hat sich bisher aber allen Realisierungsversuchen widersetzt. In den letzten Jahren hat es jedoch rasante Fortschritte bei der Effizienz Silizium-basierter Lichtemitter gegeben, sogar optischer Gewinn (gain) wurde berichtet. Ich möchte diese Entwicklung zusammenfassen und dann unsere Unterschungen an Bor-implantierten Si pn Dioden und an mit seltenen Erd-Ionen implantierte MOS-Strukturen präsentieren, deren Effizienzen schon nahe zum anwendungsrelevanten Bereich kommen.]]></dc:description>

<dc:description><![CDATA[The time-dependent flux over the fission barrier of an excited nucleus under the influence of dissipation is investigated. Characteristic features of the evolution of the amplitude of the probability distribution and the velocity profile at the fission barrier are derived. Analytical results are compared to numerical Langevin calculations and used to develop a new analytical approximation to the solution of the Fokker¿Planck equation for the time-dependent fission-decay width. This approximation is
shown to be more realistic than previously proposed descriptions, which were widely used in the past.]]></dc:description>

<dc:description><![CDATA[The production of K+-mesons in pA (A = D: Q Cu, Ag, Au) collisions has been investigated at the COoler SYnchrotroii COSY-Julich for beam energies T-p = 1.0-2.3 GeV. Double differential inclusive p C cross-sections at forward angles theta(K+) < 12&DEG; as well as the target mass dependence of the K+ momentum spectra have been measured with the ANKE spectrometer. Far below the free NN threshold at T-NN = 1.58 GeV the spectra reveal a high degree of collectivity in the target nucleus. From the target mass dependence of the cross-sections at higher energies, the repulsive in-medium potential of the K+--mesons can be deduced. Using pN cross-section parameterisations from the literature and our measured pD data we derive a cross-section ratio σ(pn --> K+X)/sigma(pp --> K+X) similar to (3-4).]]></dc:description>

<dc:title><![CDATA[Wire-mesh sensors and tomography methods developed by FZR]]></dc:title>
<dc:source><![CDATA[Seminar, 29.11.2004, Darmstadt, Germany]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[The Institute of Safety Research of the Forschungszentrum Rossendorf, Germany, has developed electrode-mesh sensors, which allow the measurement of the electrical conductivity distribution in a flow duct. This can be used either for the detection of the gaseous phase in a gas-liquid flow or for mixing studies in single phase flow, when the components have different electric conductivities. Due to the high measuring rate each bubble is mapped in several successive instantaneous frames. This allows to obtain bubble size distributions as well as bubble-size resolved gas fraction profiles beside the visualisation and the calculation of profiles of the time-averaged void fraction. The sensor is widely used to study the evolution of the flow pattern in an upwards air-water flow. The experiments aim at closure equations describing forces acting on bubbles as well as coalescence and fragmentation frequencies for the implementation in CFD-codes. Some other prominent examples of the application of wire-mesh sensors were given, like (1) boiling water reactor stability studies, (2) the visualization of cavitation at fast-acting cut-off valves, (3) the visualization of the flow structure behind a closing globe valve, and finally (4) mixing studies in single-phase flow at the ROCOM test facility in Rossendorf, which are aimed at the mixing of deborated slugs during boron dilution transients. 
 
Second subject of the paper is radiation tomography. A gamma-tomography setup for imaging a periodically changing density field is described. It is based on a time-resolved acquisition of the detector signals. It was used to visualize the gas fraction distribution within the impeller of an axial turbo-pump operating at about 1500 rpm, that delivered a gas-liquid mixture, as well as to a hydraulic clutch (coupling). In the field of X-ray tomography, the status of the development of an ultra-fast system based on a scanning electron beam is presented. An electron beam is linearly deflected over a tungsten target with a frequency of 1 kHz. X-rays generated by the traveling focus penetrate the object and arrive at a detector line placed behind the object. The detectors are read-out with a sufficiently high speed in order to obtain projections of the density distribution in different projecting directions, which change thanks to the scanning. First results showing tomographic image sequences of a phantom consisting of small spheres kept in arbitrary motion in a cylindrical test box will be presented. Moving spheres of 3 mm diameter with cylindrical holes of 1 mm diameter were resolved at a framing rate of 1 kHz.]]></dc:description>

<dc:description><![CDATA[A non-baffled stirred vessel reactor was investigated computationally with CFX-5 numerical package. The mixing of two miscible liquids with different densities was dynamically predicted from an initially stratified to a complete mixing condition. Although for a non-baffled vessel an axi-symmetric behaviour can be expected, the process was regarded as three dimensional in order to demonstrate the local instabilities associated with the blade passage. Additionally, the gas phase was involved into the simulations to investigate the effect of the free surface deformation on the mixing process. The two-phase gas-liquid interactions were modelled using the free surface model. The different density liquids were comprised into the liquid phase by the means of the multicomponent model. The grid elements size was kept relatively low because of the dynamic behaviour of the liquid surface central vortex. Furthermore, the available turbulence models were considered to obtain the closest possible match with the experimental observations. In such a way, the stirred vessel hydrodynamics was dynamically calculated in 3-D in order to study the effect of the density difference.
The numerical simulations were evaluated experimentally using video visualisation technique. The lighter (alcoholic) coloured component and the heavier (water) transparent one, which were initially stratified, were brought into motion by the means of the rotating impeller and the mixing process was captured by digital camcorder and subsequently the images were digitally processed. Several points, close to vessel central line and wall, for which the optical distortion was minimal were considered for evaluation of the numerical predictions. 
The hydrodynamics of the above described system is of particular concern for many chemical and biochemical reactions engineered to take place in stirred vessel reactor. Although the initial conditions were to some extend idealised in order to avoid some complications raised by the presence on an injection, the studies showed strong influence on the density difference on the homogenisation. Such so called idealised conditions, however, also might occur in the stirred vessel, especially in the case of impeller malfunctioning. In case of impeller stoppage, i.e. breakdown, different density liquids present in the vessel might get stratified. This effect might prove to be of significant importance, especially in the case of reacting liquids for large-scale reactors operating in the industry.]]></dc:description>

<dc:source><![CDATA[European Journal of Inorganic Chemistry 22(2005), 4501-4508]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Dendritic oxybathophenanthroline ligands (generation 0 to 3) have been synthesized by treatment of 4,7-bis(4´-hydroxyphenyl)-1,10-phenanthroline with the corresponding Fréchet-type dendrons carrying a benzylic bromide function at the focal point. The complexation of copper(II) has been studied by liquid-liquid extraction using the radioisotope <SUP>64</SUP>Cu and time-resolved laser-induced fluorescence (TRLFS) measurements in organic media proving the formation of 1:3 complexes (Cu : dendritic ligand). The stability of the copper complexes is mainly determined by the 1,10-phenanthroline core element. The stability constants of the 1:3 complexes were found to be in the order of log K ~ 16 in CHCl<SUB>3</SUB>. On the other hand, increasing generation of the dendritic Fréchet-type branches leads to enhanced shielding of the copper ion from the environment. Additional information about this behaviour was obtained  by the fluorescence lifetimes which are much less influenced upon addition of copper(II) salt to solutions of the higher generation ligands.]]></dc:description>

<dc:source><![CDATA[Classical and Quantum Gravity 22(2005), 3135-3167]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[We study multi-dimensional gravitational models with scalar curvature nonlinearities of types R-1 and R4. It is assumed that the corresponding higher dimensional spacetime manifolds undergo a spontaneous compactification to manifolds with a warped product structure. Special attention has been paid to the stability of the extra-dimensional factor spaces. It is shown that for certain parameter regions the systems allow for a freezing stabilization of these spaces. In particular, we find for the R-1 model that configurations with stabilized extra dimensions do not provide a late-time acceleration (they are AdS), whereas the solution branch which allows for accelerated expansion (the dS branch) is incompatible with stabilized factor spaces. In the case of the R4 model, we obtain that the stability region in parameter space depends on the total dimension D = dim(M) of the higher dimensional spacetime M. For D > 8 the stability region consists of a single (absolutely stable) sector which is shielded from a conformal singularity (and an antigravity sector beyond it) by a potential barrier of infinite height and width. This sector is smoothly connected with the stability region of a curvature-linear model. For D < 8 an additional (metastable) sector exists which is separated from the conformal singularity by a potential barrier of finite height and width so that systems in this sector are prone to collapse into the conformal singularity. This second sector is not smoothly connected with the first (absolutely stable) one. Several limiting cases and the possibility of inflation are discussed for the R4 model.]]></dc:description>

<dc:title><![CDATA[Potential of proton microbeam in the study of dental composites. 1. Micro-PIXE mapping of Ca, Zr, Ba and Yb]]></dc:title>
<dc:source><![CDATA[17th International Conference on Ion Beam Analysis, 26.06.-01.07.2005, Seville, Spain]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In recent studies, PIXE and ERDA showed a high potential for dental composites [1, 2]. However, wide-beam IBA techniques can not explore the biomaterials' granular structure, which requires microbeam methods to be accounted for.
In this report we applied proton μPIXE for mapping the major elements in dental composites, with the aim of evaluating the method's potential. A flat sample with a smooth surface (~ 1 mm thick) of the composite previously labeled IV.a [1,2] was prepared by photopolymerization on a glass plate. Measurements were carried out at the Rossendorf nuclear microprobe with a 3.1 MeV proton beam focused to a spot of ~3 μm. Five areas ~250 x 250 μrn located ~0.5-2 mm apart of each other were mapped on the flat specimen at ~4 μm resolution. The μPIXE maps of Ca, Zr, Ba and Yb clearly evidenced the granular structure of the composite. The mineral particles revealed a polydisperse size distribution and different compositions. Thus while most mineral particles were Ca-rich and not larger than ~8 μm, a small number of much larger inclusions were seen, with size in the ~16-60 μm range and with high levels of Zr, Ba and Yb. Generally the maps of the elements were complementary, but some apparent deviations from this rule were seen in the different areas. This suggests that the mixture of mineral particles may show some degree of heterogeneity visible in the sample on a ~1 mm scale, which is comparable to the diameter of a dental filling. Therefore μPIXE mapping gives structural insight on the dental composites, potentially relevant for the study of their properties and behavior in the oral environment.

<dc:description><![CDATA[To investigate the structural and chemical heterogeneity of dental composites, we analyzed their composition both in whole maps and in selected points by μPIXE, μPIGE and μPBS (Proton Backscattering). Two qualitatively similar biomaterials labeled IV.a and V were studied. Thick disk-shaped, flat-surface samples were prepared by photopolymerization on a glass plate, and investigated at the Rossendorf nuclear microprobe with a 3.1 MeV proton beam focused to a ~3 μm spot. Areas of 250 x 250 μm² were mapped, and selected inclusions were analyzed in point mode using three detectors simultaneously. Five areas located ~0.5-2 mm apart of each other and five inclusions from a map for IV.a, as well as one area for V were analysed. Hydroxylapatite and pyrite were used as reference materials. Concentrations from μPIXE spectra were determined by GUPIX calculations. Up to 19 elements were detected, i.e. Ca, Zr, Ba, Yb (major), Fe, Sr, Hf (minor), Mn, Se, Ho (traces) by μPIXE; F, Na, Al, Si by μPIGE; and C, O, F, Al, Si, Ca (and possibly N, Na, Cl) by μPBS. As compared to IV.a, in composite V higher Ca, lower Zr and Ba, and similar Yb levels were found. The mixture in composite IV.a appeared as a heterogeneous map both on a ~1.0 and on a ~0.1 mm scale of the sample. Thus in all μPIXE maps the absolute concentrations of Ca, Zr, Ba and Yb showed rather high dispersion (relative standard deviations ~31-44 %), but the ratios Zr/Ca, Ba/Ca and Yb/Ca were largely constant. The inclusions analyzed in point mode were Zr-rich and although their relative concentrations were roughly constant the absolute ones showed very high dispersion (rel. SD ~120 %). Hence proton microprobe analysis methods are well suited to study the dental composites and to characterize in detail their heterogeneous structure.]]></dc:description>

<dc:source><![CDATA[6th METCOR Project Meeting, 12.07.2005, Sankt Petersburg, Russia]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[At the Institute of Safety Research of the FZR a finite element model has been developed simulating the thermal processes and the viscoplastic behaviour of the vessel wall. An advanced model for creep and material damage has been established and has been validated using experimental data. The thermal hydraulic and the mechanical calculations are sequentially and recursively coupled. The model is capable of evaluating fracture time and fracture position of a vessel with an internally heated melt pool.
At the Alexandrov Research Institute of Technology in Sosnovy Bor (Russia), the thermo-chemical interaction between molten corium and RPV steel is experimentally investigated. The work is done in the frame of the ISTC project METCOR. The experiments show that the ablation of the steel occurs at interface temperatures below the steel melting temperature. The ablation rate significantly depends on the chemical compostion of the corium melt.
The presentation shows a concept for using the METCOR data within the finite element model of the FZR.]]></dc:description>

<dc:source><![CDATA[Wissenschaftlich-Technische Berichte / Helmholtz-Zentrum Dresden-Rossendorf; FZR-434 2005<br>ISSN: 1437-322X]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[DYN3D is an best estimate advanced code for the three-dimensional simulation of steady-states and transients in light water reactor cores with quadratic and hexagonal fuel assemblies. Burnup and poison-dynamic calculations can be performed. For the investigation of wide range transients, DYN3D is coupled with system codes as ATHLET and RELAP5.

The neutron kinetic model is based on the solution of the three-dimensional two-group neutron diffusion equation by nodal expansion methods. The thermal-hydraulics comprises a one- or two-phase coolant flow model on the basis of four differential balance equations for mass, energy and momentum of the two-phase mixture and the mass balance for the vapour phase. Various cross section libraries are linked with DYN3D. 

Systematic code validation is performed by FZR and independent organizations.]]></dc:description>

<dc:description><![CDATA[An algebraic method for evaluating bare nucleon matrix elements of quark operators is proposed. Thereby, bare nucleon matrix elements are traced back to vacuum matrix elements. The method is similar to the soft pion theorem.

<dc:date>2005</dc:date>
<dc:description><![CDATA[Thermally wet oxidized SiO2 layers of 500 nm thickness have been implanted by sulfur ions of energy 150 keV and a dose 5 x 10(16) ions/cm(2) leading to an atomic dopant fraction of 4 at% at a mean depth of 190 nm. The cathodoluminescence spectra of these sulfur implanted SiO2 layers show besides a characteristic violet band at 405 nm a sharp and intensive multiplet structure beginning in the green region at 500 nm over the yellow-red region and extending to the near IR measured up to 820 nm. The energy step differences of the sublevels amount in average to 120 meV and indicate vibration associated electronic states, probably, of unsaturated sulfur radicals equivalent to Si-S center dot or equivalent to Si-O-S center dot substituting the former nonbridging oxygen hole center (NBOHC) equivalent to Si-O center dot as an intrinsic defect of the pure SiO2. After 1 min electron beam irradiation with a dose of 0.3 As/cm(2) the spectral multiplet structure is nearly lost but the NBO!  HC red band R (660 nm) remains.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The local structure of the chemical bond of iron ions implanted into SiO2 glasses (implantation energy, 100 keV; fluence, 1 x 10(16) cm(-2)) is investigated using x-ray emission and absorption spectroscopy. The Fe L x-ray emission and absorption spectra are analyzed by comparing them with the corresponding spectra of reference samples. It is established that iron nanoparticles implanted into the SiO2 vitreous matrix are in an oxidized state. The assumption is made that the most probable mechanism of transformation of iron nanoparticles into an oxidized state during implantation involves the breaking of Si-O-Si bonds with the formation of Si-Si and Fe-O bonds.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Recent experiments at the Experimental Storage Ring (ESR) at GSI have shown that relativistic Li-like C3+ ion beams can be cooled to an unprecedented momentum spread of dp=p ~ 10<sup>-7</sup> using a single-frequency laser tuned to the Doppler-shifted 2S1/2 -> 2P1/2 and 2S1/2 -> 2P3/2 atomic transitions. Although these results encourage the application of laser cooling to beams of other Li-like and Na-like ions at even higher energies as will be available at future storage rings at FAIR (Facility for Antiproton and Ion Research), two major concepts have to be demonstrated experimentally: First, efficient laser cooling of ion beams with large initial momentum spread, thus avoiding additional electron cooling to match the large momentum spread to the usually small momentum acceptance of the laser force. Second, all-optical measurements of the relevant beam parameters, thus overcoming the limited resolution of standard storage ring detectors such as the Schottky pickup electrode at ultra-low momentum spreads. The aim of this paper is to discuss the technical realization of these concepts as planned for an upcoming beam time at ESR.]]></dc:description>

<dc:description><![CDATA[2D simulations of isothermal liquid-liquid mass transfer subject to surface tension and buoyancy driven hydrodynamic instabilities have been carried out. Simulation is based on the numerical solution of two-dimensional equations of momentum and mass transport, using a combination of finite difference and finite volume methods. Two different cases have been considered: (1) buoyancy stable mass transfer, only surface tension driven convection occurs; (2) surface tension driven instability superseeded by buoyant convection. The faster attenuation of mass transfer coefficients in buoyancy stable situations is attributed to the merging of convection cells leading to a reduction in the number of renewal zones along the interface. Concentration profiles next to the interface reveal the diffusional nature of the mass transfer.]]></dc:description>

<dc:source><![CDATA[Monte Carlo 2005 Topical Meeting, 17.-21.04.2005, Chattanooga, United States, 0 89448 695 0]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The IBR-2 is a small fast reactor with plutonium oxide fuel and liquid sodium cooling. A ro-tating two-reflector system periodically closes and opens a non-reflected side of the reactor and leads it through the prompt super critical state in a time of about 500 microseconds. During this time a burst of fast neutrons is generated in the core of the reactor, which spreads out through moderators. Channels lead the neutrons to measurement instruments. 
Certain reactivity parameters of the rotating reflector system determine essential parameters of the reactor as a pulsed neutron source. Just now a new reflector system, the so-called PO-3, has been installed. For this reason the important reactivity effects of the reflector were newly calcu-lated with help of the MCNP-4C2 code. The contribution presents numerical results, which were obtained in different ways and compares results of calculations and measurements. The special in-terest consisted in studying the effect of neglecting the fission source effect, as assumed by the PERT option of the code, on the calculation results. The comparison of numerical with measure-ment results showed agreements in some cases but also considerable discrepancies, which could not yet be explained. Therefore, no final conclusion on the applicability of the PERT method for the calculation of total and displacement reactivity effects of the rotating reflector system of the IBR-2 reactor could be drawn.]]></dc:description>

<dc:source><![CDATA[IEEE Transactions on Applied Superconductivity 20(2010), 672]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[In this paper we consider various issues of design, fabrication, and performance of non-destructive pulsed magnets at the Dresden High Magnetic Field Laboratory. Currently, a variety of pulsed magnets are in operation in the laboratory. A 70 T/8.5 MJ magnet, having a 24 mm bore and generating field pulses of about 150 ms duration serves as a workhorse for external users and for in-house research. Smaller 6065 T/1.5 MJ magnets with a bore of 20 mm and pulse duration of 25 ms have been proven to be very reliable in operation. In addition, a new 90 T/9MJdual-coil magnet has recently achieved 87.2 T in a 20 mm bore. A 60 T/43 MJ longpulse magnet is currently tested. Questions of magnet longevity, coil monitoring, as well as magnetic-field measurements are addressed. Further magnet-technology developments and the route to 100 T are discussed.]]></dc:description>

<dc:description><![CDATA[The main luminescent centers in SiO2 are the red luminescence R(1.85eV) of the non-bridging oxygen hole center (NBOHC) and the oxygen deficient center (ODC) with a blue B(2.7eV) and a UV band (4.4eV). Implanted hydrogen diminishes the red luminescence but increases the blue and the UV bands. Thus hydrogen passivates the NBOHC and keeps the ODC's in active emission states. A preliminary model of luminescence center transformation is based on radiolytic dissociation and re-association of mobile oxygen and hydrogen at the centers as well as formation of interstitial H2, O2, and H2O molecules.]]></dc:description>

<dc:description><![CDATA[This contribution addresses self-assembling of  Si-nanocrystals (NCs) in gate oxides, with special emphasis on size and position tailoring and their application as discrete charge storage centers in nanocrystal memories. The Si NCs for these multi-dot floating-gate memories have been produced by ion irradiation through SiO2/Si-interfaces. Si excess within SiO2 is formed by ion beam mixing of Si from the Si substrate and from the poly-Si capping layer into the gate oxide. Ion irradiation with 3x1015 -10x1015 Si+ cm-2 at 50-100 keV through 50 nm poly-Si and 15 nm SiO2 on (001)Si results in a considerable Si excess. At the upper and lower interfaces of the gate oxide, this ion irradiation forms a metastable SiOx composition. Si NCs are formed by phase separation into Si and SiO2 during post-irradiation thermal treatment. Adjacent to the recovering interfaces, narrow SiO2 zones becomes denuded of excess Si. More distant excess Si precipitates as Si NCs in the gate oxide. This approach was applied to nMOSFET-NC-memory fabrication in the standard CMOS line at ZMD. MOSFET characteristics in terms of write/erase voltage, duration of the programming time, endurance and retention have been evaluated.]]></dc:description>

<dc:description><![CDATA[The origin of ferromagnetism in ZnO single crystals implant-doped with Fe is investigated using X-ray diffraction, transmission electron microscopy, superconducting quantum interference device magnetometry and Mössbauer spectroscopy. For an ion fluence of 4×1016 ions per cm2 and an implantation temperature of 620 K, Fe nanoparticles are responsible for room-temperature ferromagnetism of the ZnO single crystals. On the other hand Fe ions implanted with an ion fluence of 4×1015 ions per cm2 at a temperature of 253 K develop a ferromagnetic coupling within the host matrix. Consequently only high resolution methods allow to rule out secondary phases in doped magnetic semiconductors.]]></dc:description>

<dc:description><![CDATA[Due  to the lattice misfit between the silicon and the silicon carbide lattices the epitaxial deposition of  SiC layers normally results in a highly defected carbide layer. Short time annealing seems to be an effective method to improve the crystal structure of the epitaxial layer using intense light pulses from flash lamps.   
From the present point of view the annealing mechanism is based on the rapid melting of a thin silicon interface layer due to the intense light pulse, giving the non molten SiC layer the possibility for relaxation and annealing. Consequently, after the pulse is over and the liquid silicon intermediate layer solidifies epitaxially on the monocrystalline substrate one receives a high temperature annealed epitaxial SiC on silicon structure.
Although the annealing of the SiC layer due to the flash irradiation could be verified by TEM investigations a serious problem remains, connected with the facetted melting of the monocrystalline silicon surface after rapid heating above the melting temperature. Due to the layer by layer crystallisation within the molten pyramides, including a lateral growth component and due to the 5 % higher density of liquid silicon in comparison to solid silicon a surface relief will be formed after the solidification process is completed.  
Two techniques were tested to circumvent the deep facetted melting. 
The first procedure to homogenize the melting depth is based on the introduction of a so called melt stop layer in a certain depth below the SiC / Si interface. For this purpose carbon admixture which increases the melting temperature of silicon was implanted at a dose of  2*1017cm-2 and a energy of 140 keV through a 30 nm thick SiC layer into silicon, forming a approximately 200 nm thick melt barrier in a depth of 400 nm. 
As a further possibility to prevent the facetted melting ion implantation of germanium admixture as a element reducing the melting temperature of silicon was tested. 
It could be experimentally shown that both, the introduction of a melt stop layer at any depth behind the Si / SiC interface as well as the modification of the silicon surface, leading to a decrease of the silicon melting temperature, are usefull methods for the homogenization of the melting depth at the bulk silicon surface.]]></dc:description>

Bearing in mind the so-called [2 + 1] mixed ligand approach for the development of target-pecific radiopharmaceuticals, reactions of 1 with isonitriles carrying the (2-methoxyphenyl)piperazine pharmacophore (part of WAY 100635) were also studied and the complexes [Re{kappa(2)-H(mu-H)B(tim(Me))(2)}(C equivalent to N-R'-WAY)(CO)(3)] (R' = butylene (5), pentylene (6) or hexylene (7)) isolated. The novel mixed Re(I) tricarbonyl complexes (3-7) have been characterized by the usual analytical techniques, which included X-ray diffraction analysis in the cases of 3, 4 and 5. The affinity of the complexes 5-7 toward the 5-HT1A receptors was tested in competitive receptor binding assays and the IC50 values found were in the 21.9-66.5 nM range. Complex 7, with the longest spacer length between the isonitrile function and the pharmacophore, has shown an improved selectivity towards the 5-HT1A subtype of receptors when compared with 5 and 6.]]></dc:description>

<dc:description><![CDATA[Annealing of thin films of amorphous indium tin oxide (ITO) in vacuum is known to decrease their resistivity. The amorphous-to-crystalline transition is often assumed as the reason for this improvement due to a Sn donor activation, but the physical mechanisms behind the experimental observation are not clear. In present work, the films were studied during heating in vacuum within the temperature range Ta=20-330 °C at a constant rate of 5 °C/min as well as at isothermal annealing at Ta=210 °C. This study is focused on in situ spectroscopic ellipsometry (SE) monitoring of the film properties during annealing. In addition, the films were investigated by in situ four point probe resistivity measurement technique and the in situ X-ray diffraction (XRD) and elastic recoil detection analysis (ERDA). The observed temperature dependences of the ellipsometry parameters and resistivity indicate several stages with features at Ta=110, 150, 280, and 310 °C, in contrast to the more simple two-stage behavior of these characteristics obtained during isothermal annealing. Even in the XRD-amorphous state, the film resistivity significantly decreases with increasing temperature due to a free-electron density enhancement as shown by SE. It is likely caused by the generation of oxygen vacancies, because ERDA showed decrease of the oxygen content in the film on this stage of annealing. A rapid crystallization within the temperature range of 250-280 °C leads to a further decrease of the resistivity due to Sn donor activation. The amorphous-to-crystalline transition is accompanied by a film roughening as it is shown by in situ SE and corroborated by atomic force microscopy.]]></dc:description>

<dc:description><![CDATA[The write performance of a multidot memory is investigated in MOS (metal-oxide-semiconductor) capacitors. The oxide of the MOS structure on p-type Si contains a layer of ion beam synthesized Ge nanocrystals (NC's) very close to the Si/SiO2 interface. This structure is modeled in a floating gate-like approach, where the NC's are considered as individual storage nodes and charged by direct tunneling of holes. Quantum confinement and Coulomb blockade effects of small Ge NC's (1-6 nm) are discussed and found to be negligible for the present structure. A close agreement between the calculated write characteristics and experimental data clearly confirms the validity of the model. From the simulation results it is predicted that a flatband voltage shift ΔVfb = -1V could be gathered with programming times tprog < 1µs. The write parameters (pulse voltage and duration) for a given ΔVfb value are mainly determined by the distance of the NCs' to the substrate.]]></dc:description>

<dc:description><![CDATA[Optical patterns as small as 200nm width have been fabricated in a thin film of amorphous silicon carbide (aSiC:H)using a focused ion beam microscope, (FIB). Because of the low electric conductivity of aSiC:H, the diameter of the writing ion beam is broadened by the effect of surface charging which was overcome by depositing a thin layer of gold onto the aSiC:H film.

<dc:date>2012</dc:date>
<dc:description><![CDATA[We present results of μSR, dHvA, and SQUID magnetization measurements on borocarbide superconductors, which show a remarkable correlation between an order-disorder transition of the vortex lattice, observed in the μSR measurements, and enhanced additional damping of dHvA oscillations in the peak-effect region. It is, therefore, concluded that an important mechanism of additional damping of dHvA oscillations in the superconducting state should be associated with enhanced scattering of quasi particles by the pair potential in disordered vortex lattices.]]></dc:description>

<dc:description><![CDATA[MgO(001) single crystals were irradiated with 57Fe at an energy of 100 keV and an ion fluence of 6x1016cm-2 at implantation temperatures between 25°C(RT) and 1000°C.
Analysis was carried out by means of CEMS, XRD, RBS and TEM. We found that the implantation temperature plays the important role for the formation of Fe nanoparticles. The fraction of metallic Fe (CEMS Fe0 signal) increases from 28% for RT implantation to 60% for 800°C implantation, while the Fe profile remains unchanged (Rp ¡Ö 50 nm). The nanoparticles formed after 800°C implantation are about 5 nm in size and exhibit fcc-structure with an orientation relationship of Fe(111)/MgO(111) and Fe(220)/MgO(220). The nanoparticles exhibit paramagnetism at room temperature.
At an implantation temperature of 1000°C the Fe implantation profile smears out completely and 92% of the Fe atoms are found in the Fe3+
oxidation state.]]></dc:description>

<dc:title><![CDATA[Minimierung der Inter-Observer-Variabilität bei volumetrischen Auswertungen von onkologischen Ganzkörperstudien in der PET]]></dc:title>
<dc:source><![CDATA[Nuklearmedizin 44(2005), A16]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Ziel: In (1) wurde ein Verfahren vorgestellt, welches zur Eingrenzung, Analyse und quantitativen Auswertung dreidimensionaler Strukturen (VOIs) innerhalb von PET-Bildvolumen dient. Hierbei werden die VOIs halbautomatisch über eine Schwellwertanalyse detektiert und segmentiert. Da der Schwellwert durch den Anwender festgelegt wird, unterliegt das gesamte Verfahren in bestimmtem Umfang der Subjektivität des Anwenders mit entsprechender Konsequenz für die Inter-Observer-Variabilität. Das Ziel dieser Arbeit war es, die vorhandene Schwellwertanalayse so zu modifizieren, dass sie die Volumina von VOIs und hiervon abhängige Größen wie die mittlere Tracerakkumulation/SUVs reproduzierbar bestimmt.

Methodik: Der Anwender muss einen ersten Schwellwert festlegen, der in etwa dem subjektiv als korrekt betrachteten Wert entspricht. Die nähere Umgebung des Volumens definiert den Untergrund und schränkt gleichzeitig den zu betrachtenden Bereich ein. Ausgehend von diesem Hintergrund lassen sich lokale Schwllwerte definieren. Um diese Schwellwerte zu finden, muss das Niveau des Untergrundes ermittelt werden. Dies geschieht über einen Least-Squares-Fit gegen eine 3D-Hyperfläche, welcher mittels multilinearer Regression berechnet wird.

Ergebnisse: Bei den betrachteten Testdatensätzen lieferte die Methode erste viel versprechende Ergebnisse. Untersucht wurden zum einen Studien mit ortinvariante, sowie solche mit stark ortsabhängigem Untergrund. Für einen um 40 Prozentpunkte variierenden Schwellwertbereich wurden die Volumina jeweils mit und ohne Bestimmung des Untergrundes berechnet. Es zeigte sich, dass bei Studien mit ortinvariantem Untergrund die Schwankungsbreite der ermittelten Volumina von 150 Prozent auf 10 Prozent reduziert werdn konnte. Bei Studien mit stark ortsabhängigem Untergrund, z.B. an Organgrenzen, konnte eine Verminderung von 280 Prozent auf 60 Prozent erreicht werden. Hierbei spielt die Höhe des untergrundes in beiden Fällen keine Rolle, solange der Startschwellwert über dem Untergrundniveau liegt.

Schlussfolgerung: Die Methode liefert bei hinreichend ortsinvariantem Untergrund stabile Ergebnisse. Bei stark ortsabhängigem Untergrund sind Erweiterungen nötig. Vorstellbar wäre eien ortsabhängige Gewichtung des Untergrundes im Bereich zwischen Startvolumen und Untergrund, was in weiteren Tests zu untersuchen ist.]]></dc:description>

<dc:description><![CDATA[Bright green electroluminescence with luminance up to 2800 cd/m2 is reported from indium-tin-oxide/SiO2:Tb/Si metal-oxide-semiconductor devices. The SiO2:Tb3+ gate oxide was prepared by thermal oxidation followed by Tb+ implantation. Electroluminescence and photoluminescence properties were studied with variations of the Tb3+ ion concentration and the annealing temperature. The optimized device shows a high external quantum efficiency of 16 % and a luminous efficiency of 2.1 lm/W. The excitation processes of the strong green electroluminescence are attributed to the impact excitation of the Tb3+ luminescent centers by hot electrons and the subsequent cross-relaxation from 5D3 to 5D4 energy levels. Light emitting devices with micrometer size fabricated by the standard metal-oxide-semiconductor technology are demonstrated]]></dc:description>

<dc:title><![CDATA[Aluminum investment casting with magnetic field control of the mould filling process]]></dc:title>
<dc:source><![CDATA[International Symposium on Liquid Metal Processing and Casting, 18.-21.09.2005, Santa Fe, New Mexico, United States<br>Proceedings, 0-87170-827-2, 295-303]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[From a fluid mechanical point of view, the filling of the mould during aluminum investment casting processes comprises in essence a flow in a U-bend. It is characterized by a high value of the pouring velocity in the early stage, which decreases in the course of the process. This initial high velocity poses distinct problems such as entrapment of bubbles or debris. At present, different types of filters are used for the removal of inclusions, a desired secondary effect of which is a reduction of the melt velocity. 
A non-invasive contact-less solution to control the flow of liquid aluminum is the application of a static (DC) magnetic field. Numerical calculations were performed to simulate the filling process and in particular the influence of the field. The free surface problem, which occurs in the riser of the casting unit, was taken into account by a volume-of-fluid method. 3D transient calculations employing the commercial finite-element code FIDAP were carried out for a simplified model system as well as for the real aluminum casting unit. The term for the electromagnetic force was implemented via a user defined subroutine while an additional equation for the electrical potential was solved. End effects owing to the limited size of the magnet poles were taken into account.
In parallel to the simulations, model experiments were performed using the eutectic alloy InGaSn (Tmelt = 10oC). The casting unit was modeled by a perspex pattern, and ultrasonic Doppler veloci­metry was applied for detailed acquisition of velocity data. Such measurements constitute a profound basis for the validation of the numerical simulations. On account of the excellent agreement, an up- scaling towards the realistic aluminium casting process is justified. 
Finally, realistic tests with liquid aluminium were performed at an industrial installation. The primarily aimed at influence of the magnetic field, i.e. the attenuation of velocity peaks in the beginning of the process, could be clearly demonstrated. In a second set of experiments, the strength of the DC field was adapted to the process. At start-up, the maximum braking force was applied for a fixed time, followed by a reduction with increasing filling-level of the casting unit. This schedule provided a distinct damping of the peak velocities without the drawback of a significant prolongation in filling time. A remarkable diminishment of defects in the casting product could be achieved.]]></dc:description>

<dc:title><![CDATA[Entwicklung von Methoden zum beschleunigten Zugriff auf Akquisitionsdaten ACS2-basierter PET-Scanner]]></dc:title>
<dc:source><![CDATA[Nuklearmedizin 44(2005), A161]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Ziel: ACS2-basierte PET-Scanner wie der weit verbreitete ECAT HR+ unterliegen auf Grund von Hardwarelimitationen nicht nur einigen allgemein bekannten Stabilitätsproblemen, sondern auch der Problematik, dass ein Netzwerkzugriff auf die akquirierten Daten nur mit 0,5 MB/s möglich ist. Besonders bei der Verarbeitung von Listmodedaten, z.B. bei einer event-basierten Bewegungskorrektur, ist dies nicht tolerierbar und behindert die Überführung dieser Methoden in die Routine in erheblichem Makße (1). Unsere Studie greift dies auf und soll am Beispiel des ECAT HR+ überprüfen, inwieweit die Entwicklung von hard- und softwarenahen Methoden die Stabilität des ACS2 verbessern, vor allem aber den Zugriff auf die Daten wesentlich beschleunigen kann.

Methodik: Beim ACS werden die akquirierten Daten über einen SCSI-2 Bus auf eine Festplatte abgespeichert. Dieser Bustyp bietet eine Höchstgeschwindigkeit von 10 MB/s, wobei er jedoch bei einer Datenübertragung per Netzwerk durch die Limitationen des ACS2 kaum an sein Limit gerät. Um dies zu verbessern, wurde das ACS2 mit einem von zwei getrennten Hostanschlüssen eines SCSI-RAID System verbunden. Ferner wurde ein auf Linux basierender Rechner an den zweiten Anschluss angeschlossen, um beide Rechnersystemen einen physischen Zugriff auf das RAID System zu ermöglichen. Im Rahmen einer Softwareentwicklung wurde dann das vom ACS2 verwendete Dateisystem auf Linux portiert, um von dort aus auf die Daten zugreifen zu können. Um einen transparenten Zugriff auf die Daten zu erhalten und diese unmittelbar nach jeder Messung vom ACS2 auf die Akquisitionsworkstatin zu verschieben, wurden Shellskripte in Messprotokolle des PET-Scanners integriert.

Ergebnisse: Durch den Einsatz eines Ultra1 60 SCSI-RAID Systems konnten mit Hilfe eines parallel betriebenen Linux-Rechners beträchtliche Geschwindigkeitenszuwächse erzielt werden. Im Gegensatz zu der vormals auf 0,5 MB/s limitierten Methode, ist es nun möglich, mit einer Transferrate von 70 MB/s die Akquisitionsdaten zu übertragen bzw. Zugriff darauf zu erhalten.

Schlussfolgerungen: Durch die erzielte Geschwindigkeitssteigerung konnte ein langjähriger Limitationsfaktor beim akquirieren großer Datenmengen mit ACS2-basierten PET-Scannern eliminiert werden. Die entwickleten Methoden erlauben es nun, im vertretbaren Zeitrahmen Zugriff auf die Akquisitionsdaten zu erhalten und dsind darüber hinaus in der Lage, den wie verbreiteten Stabilitätsproblemen des ACS2 entgegenzuwirken.]]></dc:description>

<dc:source><![CDATA[Journal of Crystal Growth 277(2005)1-4, 162-169]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The use of 3C-SiC wafers for device fabrication has been restricted by the high defect density in the substrates. Flash lamp annealing (the FLASiC process) has been shown to reduce the defect density in 3C-SiC by at least an order of magnitude. This process involves melting a layer of silicon in contact with the 3C-SiC layer on a time scale of milliseconds and the subsequent regrowth of the SiC layer by liquid phase epitaxy. This paper shows how the transport of carbon in the liquid silicon is determined by the structure of the starting substrate and process conditions. The movement of carbon controls the dissolution and regrowth of the SiC and determines the morphology of the regrown film.]]></dc:description>

<dc:title><![CDATA[Automatic coregistration of whole-body positron emission tomography images using piece-wise rigid body transformations]]></dc:title>
<dc:source><![CDATA[Annual Conference of the Academy of Molecular Imaging, 18.-23.03.2005, Orlando, Florida, USA]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The coregistration of whole body PET images runs into certain problems. On the one hand if one uses non-rigid transformatin the validity of the data might be compromised. On the other hand if one uses only rigid body transformations, it is hardly possible to take all details of the images into account. We developed a method that circumvents this problem by using piecewise rigid body transformation.

This method evaluates the alignment of the images by the correlation of intensities and the mutual information of the data. The best transformation parameters are searched for by a modified conjugate gradient method.

The complete functionality is implemented in form of a libarary, which might be linked to an application. A command line and graphical user interface is provided. This program allows to define several areas in the images on which a separate coregistration is performed. All areas can be viewed in the same transformed image. The regions in between are interpolated by a Fermi box for each area in order to keep as much of the original information as possible.

The user interaction is reduced to a minimum, besides the coregistration areas only some information about the image content used for optimization and acceleration might be provided. However, the method will lead to improved alignment even without this additional information.

We will present the method as well as result for the different fields of application, e.g. follow up studies or dynamical studies.]]></dc:description>

<dc:title><![CDATA[Imaging of neurotensin receptors in tumors by a novel stabilized <SUP>64</SUP>Cu-DOTA-neurotensin analog]]></dc:title>
<dc:source><![CDATA[21st Meeting of the European Association for Cancer Research (EACR-21), 26.-29.06.2010, Oslo, Norway]]></dc:source>

<dc:description><![CDATA[Background: 
Neurotensin (NT) and its receptors (NTR) are overexpressed in various tumors (breast, prostate, lung, ductal pancreas, pituitary) and play a crucial role in tumor progression and malignancy. For tumor diagnosis and optimized targeted, individualized therapy it is important to image and quantify functional expression of these receptors. The development and radiopharmacological characterization of a novel stable neurotensin analog radiolabeled with <SUP>64</SUP>Cu is described.

Material and methods: 
The peptide (ArgΨ(CH<SUB>2</SUB>NH)ArgProdmTyrtLeuLeu-OH) was synthesized by manual solid phase synthesis on a Merrifield-resin and conjugated with DOTA (1,4,7,10-Tetraazacyclododecane-1,4,7,10-tetraacetic acid). Radiolabeling of the peptide (3 nmol) with <SUP>64</SUP>CuCl<SUB>2</SUB> was carried out in 0.1 M ammonium acetate at pH 5.5, 37°C and 15 min. The IC<SUB>50</SUB> was determined on HT-29 cell membranes. Cell uptake and internalization was studied in HT-29 and PC3 cells. The biodistribution of the radiotracer was investigated in HT-29 tumor bearing NMRI nu/nu mice (5 min, 60 min p.i.; 4 animals per time point) and imaged by small animal PET (8 animals). The metabolic stability was analyzed in Wistar rats.

Results: 
The binding affinity of the radiotracer towards NTR1 was 7 nM (4-12 nM, 95% confidence interval). The radiochemical purity after one step radiolabeling was greater than 92%. After single intravenous administration the activity concentration increased fast in the tumor (0.8±0.1 SUV, 5 min p.i.) and decreased to 0.3±0.1 SUV (60 min). At 60 min p.i. the tumor to organ ratios were 2.8±0.7 (blood), 5.2±0.9 (muscle), 4.2±0.6 (pancreas), 0.6±0.5 (liver), and 0.4±0.4 (kidneys). The radiotracer was fast accumulated in the kidneys (3.7±0.6 SUV, 5 min p.i.; 0.8±0.1 SUV, 60 min p.i.) and eliminated in the urine (60±6% injected dose, 60 min p.i.). The tumors were clearly delineated in the PET images. The tumor uptake of the radiotracer was competitively inhibited by 73% by simultaneous injection of the neurotensin derivative 8-13. In rat plasma 33% of the radioactivity accounted for the original compound at 60 min p.i.

Conclusions: 
The novel <SUP>64</SUP>Cu-neurotensin analog with good stability and high receptor affinity allows for the in vivo imaging and functional characterization of NTR1 receptor overexpressing tumors. These findings are a prerequisite for other imaging applications, e.g., using SPECT radionuclides (<SUP>111</SUP>In), and potentially also for targeted radionuclide therapy (<SUP>67</SUP>Cu, <SUP>90</SUP>Y or <SUP>177</SUP>Lu).

<dc:description><![CDATA[This work is part of our efforts to develop chelating agents for stable binding and easy conjugation of rhenium-188 to biologically interesting structures. Keeping in mind the high in vivo stability of [<SUP>188</SUP>ReO(DMSA)<SUB>2</SUB>]<SUP>-</SUP> (1) we want to exploit this coordination system for the design of <SUP>188</SUP>ReO(V) chelates which are stable towards re-oxidation to perrhenate and towards ligand exchange under all conditions of radiopharmaceutical procedures and applications.
The new type of tetradentate ligand has been synthesized by bridging two molecules of dimercaptosuccinic acid (DMSA) with an alkylene triamine chain. The resulting stereo-isomeric tetrathiolato S<SUB>4</SUB> ligand 1 forms five-coordinate oxorhenium(V) complexes 2 (exo-cis) and 3 (exo-trans) by ligand exchange reaction of NBu<SUB>4</SUB>[ReOCl<SUB>4</SUB>] in methanol. Without addition of base the compounds will be isolated as betain, [ReO(S<SUB>4</SUB>)], with the protonated nitrogen of the bridge as internal counter ion. X-ray crystal structure determination of both stereoisomeric forms reveals the square-pyramidal coordination geometry of the ReOS<SUB>4</SUB> core. The orientation of the metal-oxo core is exo in relation to the carbamido groups in both isomers. 
The activated BFCA 4 enables easy linking of biomolecules containing a terminal amino group. Prototypic model conjugates with tripeptides have been identified in non-radioactive form by electrospray mass spectrometry. 
The Re-188 labelling procedure runs fast, in good yields and under mild conditions, making the new complexes interesting as a further access to stable rhenium-188 radiotherapeutics.]]></dc:description>

<dc:description><![CDATA[Polyoxometallate (POMs) gewinnen zunehmend an Bedeutung im Hinblick auf eine Anwendung in der Medizin [1]. Aufgrund ihrer bekannten antiviralen und antitumoralen Eigenschaften werden insbesondere Clusterverbindungen auf der Basis von Polyoxomolybdaten, -wolframaten sowie -vanadaten intensiv untersucht. Eigenschaften wie hohe Stabilität, geringe Toxizität, hohe Wirksamkeit und eine steuerbare Bioverteilung sind für eine Anwendung von POMs in der Medizin von besonderem Interesse. In diesem Zusammenhang ergeben sich durch Modifizierung der POMs mit organischen Verbindungen vielfältige Möglichkeiten. Besonders aussichtsreich erscheint die Anwendung von Kern/Hüll-Nanoteilchen mit einem Durchmesser von < 100 nm. So ergibt sich im Vergleich zu freien Clusterverbindungen eine höhere antitumorale Aktivität, wenn mit Stärke umhüllte nanometergroße Teilchen eingesetzt werden [2].
Unsere Untersuchungen haben gezeigt, dass die Darstellung von hydrolytisch stabilen Nanoteilchen auf der Basis von Polyoxowolframaten mit dem Biopolymer Chitosan möglich ist. Durch Vermischen von wässrigen Lösungen der Clusterverbindung K7[Ti2W10PO40] und einem Chitosanderivat (Mr ~ 10.000 g/mol) erhält man nanometergroße Assoziate. Diese Nanopartikeln weisen eine definierte Stöchiometrie (~ 5 Clustermoleküle/Molekül Chitosan) auf und die Teilchengröße liegt im Bereich von etwa 40 nm bis 400 nm, wobei der überwiegende Anteil <100 nm ist. Erste Untersuchungen zur Aufnahme in Tumorzelllinien haben ergeben, dass die Assoziate von K7[Ti2W10PO40] mit Chitosan im Vergleich zum freien Polywolframat deutlich besser aufgenommen werden.

<dc:description><![CDATA[In oder to understand relationships between the structure of rhenium-188 '4+1' complexes and their in vitro stability we synthesized a series of rhenium model complexes and determined their stability in human plasma. Rhenium-188 '4+1' complexes were synthesized using different monodentate phosphorus(III) ligands, including both lipophilic and hydrophilic tertiary phosphines and phosphites (188Re1-3) and unsubstituted tetradentate ligands and substituted NS3 ligands bearing a carboxyl group or an isopropyl amide were used as chelators (188Re4-6). As instability in aqueous solution leads always to perrhenate, the amount of 188ReO4- formed after 1h, 24 h and 48 h was determined by TLC.

<dc:source><![CDATA[Materials Science and Engineering C 26(2006), 818-821]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[A mass separated focused ion beam (FIB) is a very useful tool to fabricate nanostructures by writing implantation within an ion beam synthesis process. In these investigations the IMSA-OrsayPhysics FIB, equipped with a Co36Nd64 alloy liquid metal ion source, was applied. Si(100) and (111) wafers were implanted with 60 keV Co++ ions in the dose range of 2E16 to 2E17 cm-2. Implantation parameters were investigated, like pixel dwell time, relaxation time (time between two cycles), dose rate as well as the pixel overlapping factor. The subsequent annealing was done in a two step process, namely 600°C for 60 minutes and 1000°C for 30 minutes in a N2 ambient. The results obtained by SEM investigations in terms of continuous nanowire structures following the <110> direction and interrupted CoSi2 pattern in the <100> direction show a clear dependence on the time scale as well as the scanning mode of the irradiation. Structure sizes as small as 10 nm are demonstrated. The formation of CoSi2 nanostructures is explained by precipitation, Ostwald ripening and coarsening leading to a shrinking of the initial implanted profile.]]></dc:description>

<dc:description><![CDATA[Diese Arbeit ist Teil unserer Bemühungen, Chelatbildner zur stabilen und unkomplizierten Bindung von Rhenium-188 an biologische interessante Strukturen zu entwickeln.

<dc:description><![CDATA[The qualification of Computational Fluid Dynamics (CFD) codes for two-phase flows is an important topic in the frame of German CFD initiative initiated by the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS). This concerted action especially aims on phenomena in the primary system of light water reactors. The Transient twO Phase FLOW (TOPFLOW) test facility is one of the reference experimental facilities within this CFD network. One type of experiments aims on generation of CFD-grade data (i.e. data with high resolution in space and time) for poly-dispersed bubbly flows. Such data were obtained at the TOPFLOW facility for upwards vertical pipe flow using the wire-mesh sensor technique. Different experimental series were done for adiabatic air-water and steam-water flows as well as for condensing and evaporating flows. Beside bubbly flows the database also comprises measurements for slug, churn-turbulent and wispy-annular flows. The aim of this presentation is to give an overview on the available database.]]></dc:description>

<dc:description><![CDATA[The qualification of Computational Fluid Dynamics (CFD) codes for two-phase flows is an important topic in the frame of German CFD initiative initiated by the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS). This concerted action especially aims on phenomena in the primary system of light water reactors. The Transient twO Phase FLOW (TOPFLOW) test facility is one of the reference experimental facilities within this CFD network. One type of experiments aims on generation of CFD-grade data (i.e. data with high resolution in space and time) for poly-dispersed bubbly flows. Such data were obtained at the TOPFLOW facility for upwards vertical pipe flow using the wire-mesh sensor technique. Different experimental series were done for adiabatic air-water and steam-water flows as well as for condensing and evaporating flows. Beside bubbly flows the database also comprises measurements for slug, churn-turbulent and wispy-annular flows. The aim of this presentation is to give an overview on the available database.]]></dc:description>

<dc:title><![CDATA[Diffusion of Humic Acid in Clay]]></dc:title>
<dc:source><![CDATA[Institutsseminar, 21.06.2005, Villigen-PSI, Switzerland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The impact of organic matter on the migration of actinides in argillaceous media is relevant for the risk assessment of future nuclear waste repositories. The diffusion of a 14C-labelled synthetic humic acid in compacted Georgia kaolinite and its influence on the uranium(VI) migration was studied. 
The migration of humic acid in clay is governed by diffusion. The colloidal properties of humic acid result in a size exclusion from small pores. Thus the accessible pore space decreases and the tortuosity of the diffusion path increases compared to a conservative tracer. Furthermore, the compacted clay filters large humic colloids. Both effects restrict the diffusive flux of humic acid in the clay. 
Diffusion experiments on the time scale of several weeks could not demonstrate a humic colloid-borne migration of uranium(VI) in the clay system. The competition of the humate and surface binding sites for uranium as well as the kinetics and reversibility of the complexation govern the actinide migration in this system.]]></dc:description>

<dc:source><![CDATA[Nuclear Physics A 764(2006), 338-370]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Invariant mass spectra of di-electrons stemming from bremsstrahlung processes are calculated in a covariant diagrammatical approach for the exclusive reaction Dp to p<sub>sp</sub>npe<sup>+</sup>e<sup>-</sup> with detection of a forward spectator proton, p<sub>sp</sub>. We employ an effective nucleon-meson theory for parameterizing the sub-reaction np to p<sub>sp</sub>npe<sup>+</sup>e<sup>-</sup> and, within the Bethe-Salpeter formalism, derive a factorization of the cross section in the form dsigma<sub>Dp to p<sub>sp</sub>npe<sup>+</sup>e<sup>-</sup></sub>/dM = dsigma<sub>np to p<sub>sp</sub>npe<sup>+</sup>e<sup>-</sup></sub>/dM x kinematical factor related solely to the deuteron (M is the e<sup>+</sup>e<sup>-</sup> invariant mass). The effective nucleon-meson interactions, including the exchange mesons pi, sigma, omega and rho as well as excitation and radiative decay of Delta(1232), have been adjusted to the process pp to pp e<sup>+</sup>e<sup>-</sup> at energies below the vector meson production threshold. At higher energies, contributions from omega and rho meson excitations are analyzed in both, NN and Dp collisions. A relation to two-step models is discussed. Subthreshold di-electron production in Dp collisions at low spectator momenta is investigated as well. Calculations have been performed for kinematical conditions envisaged for forthcoming experiments at HADES.]]></dc:description>

<dc:description><![CDATA[Ziel ist es radioaktive Kupfer(II)-Komplexe hoher Stabilität mit einstellbarer Bioverteilung auf der Basis von 3,7-Diazabicyclo[3.3.1]nonan (Bispidin) zu entwickeln. Voruntersuchungen haben gezeigt, dass insbesondere sechszähnige Liganden ein hohes inhärentes Anwendungspotential für die Radionuklidtherapie aufweisen. [1] 
Es wird die Darstellung neuer sechszähniger Bispidinderivate mit Pyridin- und Imidazolgruppen präsentiert. Die Komplexbildungseigenschaften gegenüber Kupfer(II) sowie Möglichkeiten zur Kopplung von Biomolekülen werden diskutiert.
Die Synthese der Bispidinliganden (1) erfolgt durch zwei aufeinanderfolgende Mannich-Kondensationen, wobei Pyridin- und Imidazol-Edukte variieren.

Von ausgewählten Vertretern wurden kristalline Kupfer(II)-Komplexe isoliert und die Struktur mittels Röntgendiffraktometrie gelöst. Weiterhin erfolgten Untersuchungen zur Langzeitstabilität dieser Kupfer(II)-Komplexe in Anwesenheit der Konkurrenzliganden Glutathion und Histidin mittels UV/Vis-Spektroskopie.]]></dc:description>

<dc:description><![CDATA[During the past we have studied the complex formation behavior of uranium(VI) towards several aromatic carboxylic acids. These studies were continued, so that the formation constants of the monohydroxo- and dihydroxo- as well as some trihydroxobenzoic acids are available. A short review of these formation constants will be given.
Besides this we have compared the complex formation constants to the protonation constants of the carboxyl group. A linear relationship between these two properties was found. An decreasing protonation constant is connected to an increasing complex formation constant.
Nevertheless some exceptions of this rule were observed. These deviations can be explained by the different type of complex formation between uranium(VI) and the organic ligand. This concerns especially the number and position of the hydroxo groups in phenolic carboxylic acids. In the case of 2,3-dihydroxybenzoic the two OH-groups are involved in the complex formation already at relative low pH values. During the complex formation two protons are released from the organic ligand. The formed complex does not include the carboxylic group. The two phenolic hydroxo groups form a stable five atom ring with the uranylion. This result could be confirmed by EXAFS measurements.]]></dc:description>

<dc:source><![CDATA[European Physical Journal A 25(2005)2, 211-222]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The β decay of 103Sn, a three-neutron-particle nucleus with respect to the 100Sn core, was investigated at the GSI on-line mass separator using an array of 17 germanium crystals and a total absorption spectrometer. A total of 31 β-delayed γ-rays (29 new) of the 103Sn →103 In decay were observed and, on the basis of β-γ-γ coincidences, the 103Sn decay scheme was established for the first time. By means of total absorption spectroscopy, β intensities, the Gamow-Teller strength distribution and the summed Gamow-Teller strength value of 3.5±0.5 were determined for this decay. Its half-life and QEC value were found to be 7.0±0.2 s and 7.64±0.7 MeV, respectively. The β-delayed proton branching ratio was measured to be 1.2±0.1%. The results are discussed in comparison with shell-model predictions based on realistic and empirical interactions.]]></dc:description>

<dc:description><![CDATA[We compare our quasi-particle model with recent lattice QCD results for the equation of state at finite temperature and baryo-chemical potential. The inclusion of the QCD critical end point into models is discussed. We propose a family of equations of state to be employed in hydrodynamical calculations of particle spectra at RHIC energies and compare with the differential azimuthal anisotropy of strange and charm hadrons]]></dc:description>

<dc:title><![CDATA[Measurement of bubble velocity profiles and turbulent diffusion coefficients of the gaseous phase in rectangular bubble column using image processing]]></dc:title>
<dc:source><![CDATA[Experimental Thermal and Fluid Science 29(2005), 851-860]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The flow in a rectangular bubble column with a cross-section of 100x20 mm and a height of 1500 mm was studied using a high-speed video system. Series of the images were taken at a frequency of 500 Hz at different elevations. The images were treated by means of a bubble recognition algorithm. It allows the tracking of most of the individual bubbles in a bubble swarm. Time-averaged velocity profiles and turbulent diffusion coefficients were derived as a function of the superficial gas velocity. 
To measure the turbulent diffusion coefficient of the gaseous phase the lateral displacement of bubbles traveling over a certain vertical distance was transformed into a probability density distribution. It was found that the shape of distributions fits well to a Gaussean standard distribution. Dispersion coefficients were found to grow nearly proportionally to the square root of the vertical distance. Diffusion coefficients were calculated from the proportionality factor and were compared to correlations from the literature. Experiments were performed at superficial gas velocities ranging from 0.5 to 4 mm/s. The bubbles were generated either by a porous sparger or a set of capillaries placed at the bottom of the column. Measurements were taken at heights between 1 and 1.5 m, where the bubble cloud was occupying the entire cross section.]]></dc:description>

<dc:description><![CDATA[At the experimental carbon ion tumour therapy facility at GSI Darmstadt, in-beam positron emissions tomography (PET) is used to monitor the dose delivery precision. A dual head positron camera has been assembled from commercial detector components in order to measure the β+-activity, induced by the irradiation, simultaneously to the dose application. Despite the positive clinical impact, the image quality is limited by the low counting statistics, orders of magnitude below that in standart PET applications to nuclear medicine. This paper investigates the origin for the noisy acquisition during particle extraction from the synchrottron of GSI. The results demonstrate the failure of standard random correction techniques due to a γ-ray background correlated in time with the carbon ion beam microstructure. This prevents the use of data acquired during beam extraction for imaging. The loss of counting statistics is expected to rise further at the future hospital-based facility at Heidelberg, due to a more efficient utilisation of the accelerator resulting in shorter beam pauses and a reduced treatment time. In respect, this paper provides the basis for a new data acquísition concept tailored to the unconventional application of in-beam PET imaging to therapy monitoring at radiofrequency pulsed radiation sources.]]></dc:description>

<dc:description><![CDATA[The oxygen concentration in Nd-Fe-B alloy was determined with secondary ion mass spectrometry (SIMS) using Cs+-ions. The SIMS measurements were calibrated with oxygen-implanted single crystals. The depth profile of Nd2Fe14B single crystals displays a 0.5 μ m thick surface layer with elevated oxygen concentration which can be distinguished from the matrix with an oxygen content c(O) = 0.006&PLUSMN; 0.002 at%. Polycrystalline samples can exceed this value by far and are sensitive to processing parameters and sample handling. SIMS measurements revealed the oxygen content of the Nd2Fe14B phase considerably lower than the total oxygen content of Nd-Fe-B samples. © 2004 Elsevier B.V. All rights reserved.]]></dc:description>

<dc:description><![CDATA[To handle the present shortage of Mo-99 in the nuclear medicine community, we offer alternative preparations for lung scintigraphy, Ga-68-labelled DOTA microspheres (DOTA MS) and labelled aerosol, analogously to well-known Technegas.
Over the last three decades, several trials have been made to label HSA microspheres with Ga-68 in an efficient manner and with stability. Biodegradable albumin microspheres (HSAM) have been widely applied for lung perfusion scintigraphy (Tc-99m HSAM) or labelled with Re-188 for internal radiation therapy. We present in vitro and in vivo stability data of Ga-68 DOTA HSAM in Wistar rats. 
DOTA-Bz-NCS was reacted with HSAM and labelled with Ga-68 from a Ge-68/Ga-68 generator by a simple and reproducible method in high yields. The in vitro stability of Ga-68-labelled DOTA-HSAM was checked by incubation in human plasma and by challenging with DTPA. 
After intravenous injection into a tail vain, the Ga-68 DOTA MS was rapidly filtered from venous blood and accumulated almost quantitatively in the lungs. Radioactivity level then remains constant for at least 30 min (PET studies with microPET P4). Ga-68-labelled particles showed high in vitro stability and almost quantitative accumulation in the lungs after intravenous application. We consider that Ga-68 DOTA HSAM is a potential radiotracer for lung and other organ perfusion studies.
On the other hand, for ventilation, Ga-68 Galligas aerosol for PET imaging is simple to produce in a Technegas apparatus which can produce Ga-68 eluate concentrated in acetone/HCl. It was stable in vivo (tested over 3.5 h) and allows PET imaging in man with 5–10 MBq Ga-68 only.]]></dc:description>

<dc:description><![CDATA[To handle the present shortage of Mo-99 in the nuclear medicine community, we offer alternative preparations for lung scintigraphy, Ga-68-labelled DOTA microspheres (DOTA MS) and labelled aerosol, analogously to well-known Technegas.
Over the last three decades, several trials have been made to label HSA microspheres with Ga-68 in an efficient manner and with stability. Biodegradable albumin microspheres (HSAM) have been widely applied for lung perfusion scintigraphy (Tc-99m HSAM) or labelled with Re-188 for internal radiation therapy. We present in vitro and in vivo stability data of Ga-68 DOTA HSAM in Wistar rats. 
DOTA-Bz-NCS was reacted with HSAM and labelled with Ga-68 from a Ge-68/Ga-68 generator by a simple and reproducible method in high yields. The in vitro stability of Ga-68-labelled DOTA-HSAM was checked by incubation in human plasma and by challenging with DTPA. 
After intravenous injection into a tail vain, the Ga-68 DOTA MS was rapidly filtered from venous blood and accumulated almost quantitatively in the lungs. Radioactivity level then remains constant for at least 30 min (PET studies with microPET P4). Ga-68-labelled particles showed high in vitro stability and almost quantitative accumulation in the lungs after intravenous application. We consider that Ga-68 DOTA HSAM is a potential radiotracer for lung and other organ perfusion studies.
On the other hand, for ventilation, Ga-68 Galligas aerosol for PET imaging is simple to produce in a Technegas apparatus which can produce Ga-68 eluate concentrated in acetone/HCl. It was stable in vivo (tested over 3.5 h) and allows PET imaging in man with 5–10 MBq Ga-68 only.]]></dc:description>

<dc:description><![CDATA[Measurements of the interlayer resistivity, ρ(T), under hydrostatic pressure have been performed on a low (LR)- and high (HR)-resistance variant of the title organic superconductor. While the HR sample, synthesized according to the standard procedure, shows a semimetallic-like ρ(T) behavior at high temperatures followed by the pronounced maximum around 90 K, the LR crystal, which is the result of a somewhat modified synthesis route, remains metallic for . Common to both variants is, however, an almost abrupt change in ρ(T) around , consistent with a density-wave-type instability, which below  coexists with superconductivity, and a ρAT2 dependence for TcTT0. While T* and Tc are sample independent, the values for A and T0 were found to differ markedly between both variants, inconsistent with the T2 dependence originating from coherent Fermi-liquid excitations.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[In order to introduce ferromagnetic properties, ZnO single crystals have been implanted with Gd ions at 180 keV ion energy and two different fluences. Magnetization reversal hysteresis loops have been recorded for as-implanted as well as annealed samples using a superconducting quantum interference device (SQUID). It was found that for a fluence of 5x1015 Gd+/cm2 post implantation annealing leads to an increase of the saturation moment up to 1.8 B/Gd at exactly 300 K thus excluding Gd, ZnGd or Gd2O3 secondary phases to be formed. The increase of the saturation moment can be explained along with changes in resistivity due to the annealing reported elsewhere.]]></dc:description>

Die erhaltenen Ergebnisse sind sowohl für die Risikobeurteilung als auch für die Entwicklung innovativer Sanierungs­verfahren von entscheidender Bedeutung.

<dc:description><![CDATA[Laser-Induced spectroscopic methods were often used in actinide chemistry as tool to study the speciation of these elements in aquatic environments. The main goal of the application of time-resolved laser-induced fluorescence spectroscopy (TRLFS) and laser-induced photoacoustic spectroscopy (LIPAS) is to achieve detection limits of the actinide species as low as possible or in concentration ranges expected under environmental conditions.
     With laser sources can it is possible to provide any wavelength from the near UV to the NIR (Near Infrared) wavelength range. The development of tunable solid-state lasers overcame some disadvantages of the dye laser systems as short tunable wavelength range and the use of hazardous chemicals. The application of low temperatures for samples measured with fluorescence spectroscopic methods brought effort especially in the detection of carbonate species. 
     In this contribution the focus will be mainly on the fluorescence spectroscopy of lower actinides, as it is not possible to include all literature in this field.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The experiments to synthesize thin MgB2 inter-metallic compound with the use of ion implantation and plasma pulse treatment are presented. Mg was implanted with 3e18 cm-2 of 80 keV and 5e18 cm-2 of 100 keV B+ ions and next treated with hydrogen and argon plasma pulses of duration of about 1 mu s and fluence between 2 and 4 J/cm2. Superconducting properties were examined by magnetically modulated microwave absorption (MMMA), magnetic moment and electrical conductivity measurements. The structural properties of the implanted and pulse-treated samples were examined by the X-ray diffraction (XRD) and Rutherford backscattering (RBS) methods. The main result consists in observation of MMMA hysteresis loop demonstrating the existence of superconducting regions with T-c as high as 32 K. However, the zero-resistance effect has not been obtained due to incomplete global connectivity between the superconducting regions.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Due to the sensitive detection of light fluorescence properties often are used to study the interaction of metal ions with various ligands. Several actinides  as UO2++, Am3+ and Cm3+ show intense fluorescence properties and can be detected at very low concentrations. However, for neptunium and plutonium fluorescence properties are not known up to now. Nevertheless many organic ligands present in the environment as humic substances and wood degradation products fluorescence after excitation. To study the interaction of non-fluorescent actinides with these organic ligands fs-laser pulses were used for excitation. The light emitted from the ligand is observed by ICCD-cameras in a picosecond to nanosecond time scale. Using this TRLFS system the interaction of Np(V) with several small organic ligands was studied.  As examples results will be presented for the interaction of Np(V) with 2,3-dihydroxybenzoic acid  and 4-hydroxy-3-methoxybenzoic acid. For the interaction of uranyl with 2,3-dihydroxybenzoic acid a complex formation with the phenolic OH groups was found. In the case of Np(V) the interaction is very different. At pH values below 5.0 only the interaction with the carboxylic group can be observed and the interaction with the phenolic group starts at higher pH. This results in a 2:1 complex. Studies of the complex formation of Np(V) with  4-hydroxy-3-methoxybenzoic acid at pH 6 showed also a 2:1 complex, demonstrating the Np(V) interaction with the carboxylic group and the phenolic OH group.
Nevertheless the fluorescence spectra did not show in any case a single component spectrum. This may be connected to other reactions of the non-complexed ligand. Therefore the influence of excited state reactions of the ligand will be discussed.]]></dc:description>

<dc:source><![CDATA[Experiments in Fluids 40(2006)2, 257-266]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[This work is concerned with the stabilisation of both the bulk liquid metal flow and the free surface shape in inductively heated melts. Steady magnetic fields of different orientation were used to damp fluctuations generated by an external alternating magnetic field as it is typical for an induction heater. This superposition of a driving alternating with a braking steady magnetic field was investigated experimentally at a low temperature isothermal model utilising a rectangular fluid volume in an induction--furnace--like setup fed by a current of intermediate frequency. Local velocity measurements in the liquid metal revealed quite different damping characteristics for steady fields aligned either normal or parallel to the melt surface.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Um die bisherigen Untersuchungen zur Strahlenschaden-Akkumulation in Silizium durch Ionen-Implantation auf sehr hohe Ionenstromdichten zu erweitern, wurden (100) Si-Proben mit 600 keV Si<sup>+</sup> -Ionen mit einer Stromdichte von 360 µA/cm² (2.2 x 10<sup>15</sup> Si/s/cm²) bei Substrattemperaturen von 50°C bis 400°C bis zu einer Fluenz von 10<sup>18</sup> Si/cm² implantiert. Die Implantation erfolgte mit dem Bochumer supraleitenden Ionenprojektor [J. Meijer, A. Stephan, Microelec. Eng. 41/42 (1998) 257]. Die Schädigung des Si-Kristalls in den implantierten Flächen von 185 µm Durchmesser wurde mit Hilfe der RBS/Channeling-Methode (3 MeV He-Ionen) an der Rossendorfer Mikrosonde untersucht. Für diese Messungen wurde eine zweite Messkammer mit einem 4-Achsen-Goniometer hinter der sonst zur Ionenstrahlanalytik genutzten Messkammer installiert. Die beobachtete deutliche Abhängigkeit der Strahlenschaden-Akkumulation bis hin zur kompletten Amorphisierung der bestrahlten Schicht von der Substrattemperatur und Fluenz wird diskutiert.]]></dc:description>

<dc:title><![CDATA[Field-tuned quantum critical point in CeCoIn5 near the superconducting upper critical field]]></dc:title>
<dc:source><![CDATA[Physical Review B 71(2005), 104528]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[We report a systematic study of high-magnetic-field specific heat and resistivity in single crystals of CeCoIn5 for the field oriented in the basal plane (H parallel to ab)of this tetragonal heavy fermion superconductor. We observe a divergent electronic specific heat as well as an enhanced A coefficient of the T-2 law in resistivity at the lowest temperatures, as the field approaches the upper critical field of the superconducting transition. Together with the results for field along the tetragonal axis (H parallel to c), the emergent picture is that of a magnetic-field-tuned quantum critical point which exists in the vicinity of the superconducting H-c2(0) despite a variation of a factor of 2.4 in H-c2(0) for different field orientations. This suggests that an underlying physical reason exists for the superconducting H-c2(0) to coincide with the quantum critical field. Moreover, we show that the recovery of a Fermi-liquid ground state with increasing magnetic field is more!
  gradual, meaning that the fluctuations responsible for the observed quantum critical phenomena are more robust with respect to magnetic field, when the magnetic field is applied in plane. Together with the close proximity of the quantum critical point and H-c2(0) in CeCoIn5 for both field orientations, the anisotropy in the recovery of the Fermi-liquid state might constitute an important piece of information in identifying the nature of the fluctuations that become critical.]]></dc:description>

<dc:source><![CDATA[Physical Review Letters 94(2005)18, 184506-1-184506-4]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Using a mean-field dynamo model with a spherically symmetric helical turbulence parameter alpha which is algebraically quenched and disturbed by additional noise, the basic features of geomagnetic polarity reversals are shown to be generic consequences of the dynamo action in the vicinity of exceptional points of the spectrum. This simple paradigmatic model yields long periods of constant polarity which are interrupted by self-accelerating field decays leading to asymmetric polarity reversals. It shows the recently discovered bimodal field distribution, and it gives a natural explanation of the correlation between polarity persistence time and field strength. The dependence of the persistence time on the noise shows typical features of coherence resonance.]]></dc:description>

<dc:title><![CDATA[Doping magnetic materials - tunable properties due to Cr ion implantation]]></dc:title>
<dc:source><![CDATA[348. Heraeus-Seminar "Ions at Surfaces: Patterns and Processes", 19.-23.06.2005, Bad Honnef, Deutschland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Various magnetic properties like the saturation magnetization, the Curie temperature, the coercivity and the magnetic damping behavior can easily be modified by means of ion irradiation and implantation. In combination with focused ion beam techniques even a pure magnetic patterning without changing the surface topography becomes feasible. A magnetic domain pattern can be imprinted by using ion irradiation in an applied magnetic field. Thus doping of magnetic materials opens a route to a new class of artificial magnetic materials with adjustable magnetic properties.
Here, as an example, we report on the tailoring of the magnetic properties of Permalloy (20 nm Ni81Fe19) by means of 30 keV Cr implantation. Due to the doping the Curie temperature of the Permalloy film decreases with the implantation fluence and drops below room temperature at an averaged Cr concentration of about 7 at-%. Also the saturation magnetization and the uniaxial anisotropy decrease. However the magnetic damping behavior of Cr implanted Permalloy films is strongly enhanced which is due to a combination of structural changes and alloying effects in the thin film. In order to clarify the basic mechanism for the enhancement the chemical and structural contributions to the magnetic damping parameter are separated by a comparison to results of 30 keV Ni implantation.]]></dc:description>

<dc:title><![CDATA[Rossendorfer Beiträge zur Flutung von Gruben des Uranbergbaus  Über den Einfluss des Grubenholzes auf das Verhalten von Kontaminanten im Flutungswasser]]></dc:title>
<dc:source><![CDATA[Veranstaltung, 12.05.2005, Zwickau, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Der Prozess des natürlichen Grubenholzabbaus in gefluteten Bergwerken führt zu stark reduzierenden Bedingungen im Grubenwasser. Dies hat Konsequenzen für  Kontaminanten im Flutungswasser. Insbesondere gelöstes Uran und Arsen könnten reduktiv ausgeschieden werden. Um die künftigen Redoxbedingungen im Grubenwasser zu charakterisieren, wurde das Wasser eines Hochmoors im Erzgebirge in dieser Hinsicht als nahezu gleich gearteter Fall untersucht. Das Redoxpotential im Moorwasser, gemessen mit einer Platinelektrode, sank von der Oberfläche bis in einen Meter Tiefe von etwa 600 mV auf -100 mV. Aus der Tiefenwasseranalyse und der Untersuchung des Sumpfgases, das aus dem Moorgrund extrahiert wurde, errechnete sich ein Redoxpotential von -119  5 mV. Charakteristisch für das stark reduzierende Milieu ist das Auftreten von Methan und Schwefelwasserstoff im Sumpfgas. Aus der Kenntnis dieses Zustands kann für die künftige Situation in der gefluteten Grube hergeleitet werden, dass Uran(VI) und Arsen(V) im Laufe der Zeit reduziert werden und als Uran(IV)-hydroxid und Arsen(III)-sulfid ausgeschieden werden. Durch diesen natürlichen Reinigungsprozess wird die Gefahr der Ausbreitung im unterirdischen Wasserleiter, der als Reservoir für die Trinkwasserversorgung dient, gebannt. Das Hochmoor kann in diesem Sinne als natürliches Analogon zur gefluteten Grube betrachtet werden.]]></dc:description>

<dc:source><![CDATA[Materials Science and Engineering C 27(2007), 188-192]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[The strain Bacillus sphaericus JG-A12, isolated from a uranium mining waste pile near the town of Johanngeorgenstadt, is capable of selective and reversible accumulation of U, Cu, Pb, Al, and Cd from uranium waste waters. The cells of this strain are enveloped by a surface layer protein (S-layer). The highly regular structure of this S-layer with many pores of identical size offers good binding sites for different kinds of molecules and provides nucleation sites for the formation of metal nanoclusters or minerals. In this study we demonstrate that B. sphaericus JG-A12 cells and their purified S-layer protein were capable to reduce Au to metallic nanoclusters in the presence of reducing agents such as molecular H2. The gold nanoparticles were regularly distributed and sized according to the pores of the protein lattice. The metallic nature of the clusters was confirmed by different techniques such as extended X-ray absorption fine structure (EXAFS) spectroscopy, X-ray absorption near edge (XANES) spectroscopy, UV-vis spectroscopy and X-ray powder diffraction (XRD). The size of the gold nanoparticles was estimated to be almost 1 nm. Our results demonstrate that B. sphaericus JG-A12 can be used to prepare gold nanoparticles tailor-made for industrial applications]]></dc:description>

<dc:description><![CDATA[Nanowires (NWs) and chains of nanocrystals (NCs) embedded in dielectrics or semiconductors are intensively studied regarding their potential application in nanoelectronics. CoSi2 nanostructures in Si are particularly interesting because of the full compatibility of CoSi2 with CMOS technology.
Here, we present predictive atomistic computer simulations on the ion beam synthesis of CoSi2 NWs in Si and their decay into chains of CoSi2 NCs which are applicable as plasmon waveguides. In order to simulate the Co implantation, the binary collision codes TRIDYN and TRIM were adapted to the particular experimental situation of a finely-focused Co ion beam of 50nm in width. The resulting 3D implantation profile serves as input for a kinetic lattice Monte-Carlo code by means of which nucleation and growth of CoSi2 precipitates and their coalescence into a CoSi2 NW are described. From an evolutionary viewpoint, NW synthesis and decay proceed on different time scales. The NW decay into a NC chain (Rayleigh instability) is driven by the minimization of interfacial free energy. In this regard, it will be demonstrated that the orientation of the Co implantation profile to the single crystalline Si matrix influences the stability of the synthesized CoSi2 NW. Since the system energetically favors the CoSi2(111)/Si(111) interface, driving faceting forces may occur which accelerate the NW decay into a NC chain.]]></dc:description>

<dc:source><![CDATA[DPG Jahrestagung, 04.-09.03.2005, Berlin, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Nanowires have fascinating properties. Also the kind and strength of driving forces for their structural evolution differ from macroscopic systems, thus opening new routes for their synthesis. And, with respect to interface energy, nanowires are unstable, during their decay new selforganized 1D structures evolve.
This presentation summarizes reaction pathways of the formation and decay of 1D nanostructures predicted by atomistic computer simulations. It will be shown that nanowire synthesis by phase separation from supersaturated 1D traces relies on different time scales of different processes involved: (i) phase separation is faster than long-range diffusion, thus, initially small nanodroplets form. (ii) Short-range diffusion is fast, thus, lateron the minority phase is concentrated/unified to a wire (ripening, coalescence). (iii) On a long time scale, the wire lowers its surface energy by peristaltic undulations and decays finally into large droplets (Rayleigh instability). Each process can be governed in order to fabricated functional structures. For instance, crosspoints of nanowires accelerates the wire instability locally, which leads to a nanodot separated by nm gaps from the four nanowires. Such a Si structure embedded in SiO2 might operate as a room temperature single electron transistor.]]></dc:description>

<dc:source><![CDATA[Flow Measurement and Instrumentation 16(2005)5, 277-287]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[A two-phase flow in a rectangular bubble column of 100×20 mm cross-section and 1.5 mm height was studied using a high-speed video system. Series of images were taken at different elevations at a frequency of 500 Hz. The images were processed using a bubble recognition algorithm. In such a way, an individual bubble in the gas swarm could be tracked. The time-averaged velocity profiles and the turbulent diffusion coefficients were derived as a function of the superficial gas velocity. The lateral displacement of bubbles travelling over a certain vertical distance was transformed into a probability density  distribution in order to measure the turbulent diffusion coefficient of the gaseous phase. The shape of the distributions obtained was found to fit well to the Gaussian standard distribution. The dispersion coefficients were observed to grow proportionally to the square root of the vertical distance. The diffusion coefficients were calculated from the proportionality factor and were compared with some correlations published in the literature. The experiments were performed for superficial gas velocities ranging from 1 to 6 mm/s. The bubbles were generated either by a porous sparger or a set of capillaries placed at the bottom of the column. The measurements were taken at different heights between 1 and 1.2 m where the bubble cloud was occupying the entire cross-section.]]></dc:description>

<dc:description><![CDATA[High performance Nd-Fe-B magnets are of enormous economic interest and play a key role in the development of electronics and motors. The excellent ferromagnetic properties of the Rare - Earth magnets are due to the hart magnetic Nd2Fe14B-phase (f-Phase) with high saturation polarization and magnetocrystalline anisotropy. Stoichiometric Nd-Fe-B alloys perform a peritectic reaction under near-equilibrium conditions, and the phase and microstructure selection plays a crucial role on the hard magnetic properties of this material. Besides additions and substitutes, the melt convection strongly influences the microstructure formation of Nd-Fe-B alloys, in particular the  volume fraction and grain size of the properitectic g-Fe phase which deteriorates the hard magnetic properties of the material. Numerical simulations are essential in order to understand and design the various flow structures. Therefore, the investigation of electrophysical and structure sensitive properties of the system in the liquid state prior to solidification is very important.
We present new results for the electrical and thermal conductivity, thermoelectric power and viscosity carried out in a temperature range from the liquidus (1553 K) to 1620 K. The electrical conductivity and thermoelectric power were measured using a contact 4-probe method. The thermal conductivity was investigated by a steady-state concentric cylinder method. The shear viscosity measurements were performed using an oscillating-cup viscometer. Special attention was paid to the region close to the liquidus where heating and cooling rates were reduced and the measurement steps shortened to 1 K.]]></dc:description>

<dc:source><![CDATA[NOEKS 10 - 10th International workshop on Nonlinear Optics and Excitation Kinetics in Semiconductors, 16.-19.08.2010, Paderborn, Deutschland]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[Intense THz electric fields coupling to intraband excitations can modify the interband absorption of semiconductors. A classical nonlinear mixing process is the sideband generation, where a ps NIR laser beam is mixed with the THz beam to generate sidebands at ωNIR ± n × ωTHz (integer n). In an undoped GaAs/AlGaAs multi quantum well film (substrate etched away) we observe several even-order sidebands using an all-normal-incidence geometry for the NIR and THz laser pulses [1]. Varying THz and NIR frequencies, we identify several resonances, where the intraexciton 1s-2p transition (at ~9 meV) makes the strongest contribution. Fig. 1(a) shows a typical NIR transmission spectrum with the NIR fundamental at the hh(1s) state and the resulting even-order sidebands.
In a second experiment we monitor the samples broadband transmission under THz pumping. THz light can couple and dress two resonant states, giving rise to the Autler-Townes or AC Stark effect [2, 3]. Fig. 1(b) shows the measured transmission spectra without (dashed line) and with (solid line) THz light at a THz peak intensity of 220 kW/cm² for THz pumping above (14 meV), near (10.5 meV) and below (6.1 meV) resonance. Near resonance (10.5 meV) we observe a distinct line splitting (see arrows), which represents the first clear evidence of the Autler-Townes effect in an intraexcitonic transition. Above and below resonance, low- and high-energy shoulders, respectively, are observed (see arrows). We discuss our findings on the basis of a simple two-level model that describes the situation surprisingly well near resonance up to a THz field strength of 10 kV/cm, corresponding to a Rabi energy of 0.6 times the 1s-2p transition energy. This is already well beyond the rotating-wave approximation of our model. Observed deviations would have to be addressed within a full many-body theory dealing with the complete set of excitonic states as well as with the possibility of exciton field ionization. Note that for the above parameters the ponderomotive energy is 3 meV, comparable to the exciton transition/ionization energy and the Rabi energy, an extremely non-perturbative regime with a Keldysh parameter near unity.

<dc:date>2005</dc:date>
<dc:description><![CDATA[Different methods of defect engineering are applied in this study for ion beam synthesis of a buried layer of SiC and SiO2 in Si. The initial state of phase formation is investigated by implantation of relatively low ion fluences. He-induced cavities and Si ion implantation generated excess vacancies are intentionally introduced in the Si substrate in order to act as trapping centers for C and O atoms and to accommodate volume expansion due to SiC and SiO2 phase formation. Especially the simultaneous dual implantation is shown to be an effective method to achieve better results from ion beam synthesis at implantation temperatures above 400oC. For SiC synthesis it is the only successful way to introduce vacancy defects. The in situ generation of vacancies during implantation increases the amount of SiC nanoclusters and improves crystal quality of Si in the case of SiO2 synthesis. Also the pre-deposition of He-induced cavities is clearly advantageous for the formation of a narrow SiO2 layer. Moreover, in-diffusion of O by surface oxidation can substitute a certain fraction of the O ion fluence necessary to obtain a buried homogeneous SiO2 layer. 
The results show that defect engineering for SiC and SiO2 synthesis is working. However, the implementation of a single action is not sufficient to achieve a significant improvement of ion beam synthesis. Only an optimized combination of the different versions of defect engineering can bring about pronounced better results.]]></dc:description>

<dc:description><![CDATA[The application of time varying magnetic fields can be considered as an effective tool to organize a well-defined flow structure in the liquid phase affecting the nucleation and solidification parameters. Main goal of our activities is to elucidate a strategy to control the microstructure of castings by an optimal combination of magnetic field intensity, field frequency and cooling rate. The development of fine, globular grains is preferred. Structures containing textured columnar grains and zones of macrosegregation should be avoided.
Solidification experiments as well as numerical simulations were carried out dealing with Pb Sn alloys solidified directionally from a water cooled copper chill. A rotating magnetic field (RMF) was chosen for melt agitation, because the essential features of an RMF-driven flow have already been intensively investigated for the isothermal case. The magnitude of the bulk flow in the melt generated by the RMF varies with the magnetic Taylor number Ta. The forced convection causes distinct modifications of the temperature and concentration field such as a reduction of the temperature gradient ahead of the solidification front. Without electromagnetic stirring the alloy solidifies solely in form of dendrites aligned parallel to the heat flow direction. In contrast, a transition from a columnar to an equiaxed growth (CET) is observed if the solidifying ingot is exposed to an RMF. The position of the CET is shifted towards the bottom of the casting by increasing the Ta number. The CET was found to occur for a cooling rate of about 0.4 K/s and temperature gradients in the range between 0.6 and 1.0 K/mm
The ultrasound Doppler velocimetry (UDV) was applied to measure the bulk flow during solidification. Our results show that the velocity profiles undergo distinct modifications during solidification indicating the occurrence of more sophisticated flow patterns as known from the isothermal case. Furthermore, the UDV data allow an assessment of the current position of the columnar solidification front.]]></dc:description>

<dc:description><![CDATA[Flash lamp annealing of heteroepitaxial silicon carbide on silicon structures involves melting the silicon below the SiC layer but the facetted nature of the liquid-solid interface leads to unacceptable surface roughness. This paper describes a method of controlling melting by using a melt stop created at a controlled depth below the Si / SiC interface by implanting a high dose of carbon, which significantly increases the silicon melting temperature.  Results confirm the effectiveness of the technique in reducing roughness.]]></dc:description>

<dc:source><![CDATA[Applied Physics Letters 87(2005)2, 23104]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The role of hydrogen in hydrogenated amorphous silicon (a-Si:H) has been studied from the viewpoint of its specific contribution to mechanical stress in the material. Hydrogen ion implantation has been used to increase the hydrogen concentration. In order to distinguish the effect of the changed hydrogen concentration/bonding configuration from the accompanying implantation-induced defects, a-Si:H samples with corresponding number of displacements have been studied, created using proper doses of silicon ion implantation. The experimental results have shown that it is the silicon-bonded hydrogen that essentially affects the stress, as the major contribution has its clustered bonding configuration.]]></dc:description>

<dc:description><![CDATA[The structure and magnetic properties of the nitrided compounds R<Sub>2</Sub>Fe<Sub>17</Sub>N<Sub>2</Sub> (R = Ho and Er) are studied. The type of crystal structure Th<Sub>2</Sub>Ni<Sub>17</Sub> is preserved upon nitrogenation, and the relative unit cell volume ΔV/V increase exceeds 6%. Magnetic studies are performed in fields up to 60 T at 4.2 K on aligned powder samples. Field-induced spin-reorientation (SR) transitions are observed in the M(H) curves of R<Sub>2</Sub>Fe<Sub>17</Sub>N<Sub>2</Sub>. Unlike the parent R<Sub>2</Sub>Fe<Sub>17</Sub> compounds, where the magnetization increases in steps as the field grows stronger, <Sub>2</Sub>Fe<Sub>17</Sub>N<Sub>2</Sub> demonstrate a gradual increase in magnetization. It is indicative of the change of the SR transition from first to the second type. Extrapolation of magnetization curves to the theoretical value of magnetization in the forced ferromagnetic state yields the coefficient of the inter-sublattice R–Fe exchange interaction. The inter-sublattice exchange is found to decrease upon nitrogenation.]]></dc:description>

<dc:title><![CDATA[The Becin hoard  Analysis of the ancient silver coins]]></dc:title>
<dc:source><![CDATA[17th International Conference on Ion Beam Analysis, 26.06.-01.07.2005, Sevilla, Spain]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[During the archaeological work in summer 2000 a spectacular hoard of silver coins could be excavated at the medieval site Becin, next to Ephesos / Turkey. This hoard, whose total weight amounted to approximately 30 kg, includes about 60.000 Islamic coins as well as 830 European coins and represents the largest finding of coins ever made in Turkey. One of the most outstanding features of the Becin hoard is the fact that almost all mint places recorded for the Ottoman Empire and all rulers of the second half of the 16th century up to the beginning of the 17th century are represented in this treasure. Thus, the numismatic evaluation and the material analysis of the coins will provide a general insight in the monetary and economic history of the Ottoman Empire in this time.
In a first step of the investigations a collection of 450 samples was analyzed quantitatively. Photon, electron and proton induced X-ray analysis provide complementary information on the chemical composition of the coins. Using EDXRF, the content of both the major constituent Ag and the minor elements Cu and Pb were determined. The advantage of SEM/EDX is the ability to analyze small areas of the cross-sections. Finally, PIXE measurements were carried out in order to characterize also the trace elements, like Au, Bi, Fe, Ni. The initial results show on the one hand an arrangement in different groups of coins concerning their chemical composition. On the other hand the findings illustrate frequent devaluations in the fineness of the silver coins described in the Ottoman written sources.]]></dc:description>

<dc:description><![CDATA[We studied the β-decay properties of the N=Z+1 nucleus 95Ag by measuring β-delayed  γ-rays and β-γ-γ coincidences with a plastic scintillator as  β-detector and a Ge-detector array. The 95Ag nuclei were produced by means of the 58Ni(40Ca,p2n) reaction and separated with the GSI online mass separator. The previously reported level scheme of the 95Pd daughter nucleus was extended considerably. The deduced level scheme is compared with different shell-model calculations with or without breaking the 100Sn core.]]></dc:description>

<dc:description><![CDATA[Starting with bis([1,3,4]thiadiazolo)[1,3,5]triazinium halides 1, a novel class of heterocyclic compounds, the [1,3,4]thiadiazolo[2,3-d][1,2,4]triazolo[1,5-a][1,3,5]triazinium halides 5 were prepared. The reaction between 5 and primary or secondary amines 6 yielded highly substituted guanidines 8 and fused tricyclic bis([1,2,4]triazolo)[1,5-a:10,50-d][1,3,5]triazinium halides 9. The formation of the reactive triazinium-imidothioate zwitterions 7, which is controlled by the influence of negative hyperconjugation, was proven by NMR data and the X-ray structure of 7c. The subsequent ring-closure/ring-opening steps can be understood in terms of an SN(ANRORC) process accompanied by intramolecular proton-transfer reactions. The zwitterions 7 were reacted with EtI forming cationic derivatives 10 or hydrolyzed at pH 67 to give novel heterocyclic ethanethioamide 11.]]></dc:description>

<dc:source><![CDATA[Progress in Nuclear Energy 48(2006), 830-848]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Plant-measured data provided within the specification of the OECD/NEA VVER-1000 coolant transient benchmark (V1000CT) were used to validate the DYN3D/RELAP5 and DYN3D/ATHLET coupled code systems. Phase 1 of the benchmark (V1000CT-1) refers to the MCP (main coolant pump) switching on experiment conducted in the frame of the plant-commissioning activities at the Kozloduy NPP Unit 6 in Bulgaria. The experiment was started at the beginning of cycle (BOC) with average core expose of 30.7 effective full power days (EFPD), when the reactor power was at 27.5% of the nominal level and 3 out of 4 MCPs were operating. The transient is characterized by a rapid increase in the primary coolant flow through the core and, as a consequence, a decrease of the space-dependent core inlet temperature. Both DYN3D/RELAP5 and DYN3D/ATHLET analyses were based on the same reactor model, including identical MCP characteristics, boundary conditions, benchmark-specified nuclear data library and nearly identical nodalization schemes. For an adequate modelling of the redistribution of the coolant flow in the reactor pressure vessel during the transient a simplified mixing model for the DYN3D/ATHLET code was developed and validated against a computational fluid dynamics calculation.

The results of both coupled code calculations are in good agreement with the available experimental data. The discrepancies between experimental data and the results of both coupled code calculations do not exceed  the accuracy of the measurement data. This concerns the initial steady state data as well as the time histories during the transient. In addition to the validation of the coupled code systems against measured data, a code-to-code comparison between simulation results has been performed to evaluate relevant thermal hydraulic models of the system codes RELAP5 and ATHLET and to explain differences between the calculation results.]]></dc:description>

<dc:description><![CDATA[We report here the first structural characterization of Pa(V) adducts in concentrated sulfuric and hydrofluoric solutions. In sulfuric medium, X ray Absorption Spectroscopic data show that unlike the other early actinide elements as uranium or neptunium, protactinium doesnt form a transdioxo cation but a monooxo adduct. In contrast, concentrated hydrofluoric medium precludes the formation of any oxo bond.]]></dc:description>

<dc:source><![CDATA[HAIT Journal of Science and Engineering 1(2004)4, 771-781]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[We present a theory which is able to explain enhanced magnetic quantum-oscillation amplitudes in the superconducting state of a layered metal with incoherent electronic transport across the layers. The incoherence acts through the deformation of the layer-stacking factor which becomes complex and decreases the total scattering rate in the mixed state. This novel mechanism can compensate the usual decrease of the Dingle factor below the upper critical magnetic field caused by the intralayer scattering.]]></dc:description>

<dc:description><![CDATA[The high-acceptance dielectron spectrometer (HADES) has become operational at GSI Darmstadt. The primary physics programme is to study in-medium changes of light vector mesons via their e<sup>+</sup>e<sup>-</sup> decays. The methods of dilepton signal reconstruction in the HADES spectrometer and preliminary dilepton spectra for C+C reactions at 2 A GeV are presented. In the signal reconstruction, particularly important is the reduction of the huge combinatorial background arising from e<sup>+</sup>e<sup>-</sup> combinations of leptons from gamma conversion in materials with other leptons in the collision. The purity of the dilepton signal is determined by using GEANT simulations with the full HADES geometry and a realistic detector response.]]></dc:description>

<dc:source><![CDATA[Environmental Pollution 141(2006), 42-53]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[This study evaluates chemical trends of seven acidified reservoirs and 22 tributaries in the Erzgebirge from 1993 to 2003. About 85% of these waters showed significantly (p < 0.05) declining concentrations of protons (−69%), nitrate (−41%), sulfate (−27%), and reactive aluminum (−50% on average). This reversal is attributed to the intense reduction of industrial SO2 and NOx emissions from formerly high levels, which declined by 99% and 82% in the GermanCzech border region between 1993 and 1999. The deposition rates of protons and sulfur decreased by 7090%. Since 1993, the dry deposition of total inorganic nitrogen diminished to a minor degree, but the wet deposition remained unchanged. The surface waters reflect a substantial decrease in Al exchange processes, a release of sulfur previously stored in soils, and an uptake of nitrate by forest vegetation. The latter effect may be supported by soil protection liming which contributed to the chemical reversal in almost 20% of the study waters.]]></dc:description>

<dc:title><![CDATA[Characterization of L Amino Acid Transporter 1 (LAT1) for 3-O-Methyl-6-<SUP>18</SUP>F-Fluoro-L-DOPA (OMFD) in Tumor Cells and Tumor Tissues]]></dc:title>
<dc:source><![CDATA[Fourth Annual Meeting of the Society for Molecular Imaging, 07.-10.09.2005, Köln, Deutschland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[<SUP>18</SUP>F-labeled amino acids represent a promising class of imaging agents in tumors visualized by means of positron emission tomography (PET). Because of the high uptake it is still problematic to clear differentiate between tumors and inflammation.
The high enrichment in tumor tissues assumed the uptake of the tracer via a tumor-specific amino acid transporter, which is not or different expressed in inflammatory cells suggesting a different endowment of neutral amino acids. As previously shown, L-type amino acid transporter 1 (LAT1) is playing a key role because of its high up-regulation in malignant tumors. For the functional expression of LAT1 a single membrane-spanning protein, the heavy chain of 4F2 antigen (4F2hc), essentially forms a heterodimeric complex via disulfide bonds. 
The present study investigated the amino acid transport mechanism of LAT1 for 3-O-methyl-6-<SUP>18</SUP>F-Fluoro-L-DOPA (OMFD), a novel <SUP>18</SUP>F-labeled phenylalanine derivative, into tumor cells.
For molecular characterisation of L-type amino acid transporters focusing on the LAT1-4F2hc subtype we used two different tumor cells like FaDu (squamous cell carcinoma)/HT29 (colorectal adenocarcinoma) and tumor bearing mice performing quantitative RT-PCR, Western-Blot, and immunhistochemistry. In vitro uptake assays with HT29 and FaDu were performed with OMFD under physiological amino acid concentrations. 
OMFD demonstrated a saturable and sodium- and energy-independent accumulation in vitro in different tumor cell lines, suggesting its uptake to be mediated exclusively by sodium-independent LAT1.
Our data emphasize the relevance of OMFD as a PET tracer for imaging of specific amino acid transport via LAT1 in tumors. Furthermore, the identification and characterization of tumor specific amino acid transporters like LAT1 will be a helpful tool for therapeutic implications. The inhibition of LAT1 activity in tumor cells could be effective in the inhibition of tumor cell growth by depriving tumor cells of essential amino acids, too.]]></dc:description>

OMFD demonstrated a saturable and sodium- and energy-independent accumulation in vitro in different tumor cell lines, suggesting its uptake to be mediated exclusively by sodium-independent LAT1.
Our data emphasize the relevance of OMFD as a PET tracer for imaging of specific amino acid transport via LAT1 in tumors. Furthermore, the identification and characterization of tumor specific amino acid transporters like LAT1 will be a helpful tool for therapeutic implications. The inhibition of LAT1 activity in tumor cells could be effective in the inhibition of tumor cell growth by depriving tumor cells of essential amino acids, too.]]></dc:description>

<dc:source><![CDATA[Biotechnology Advances 24(2006)1, 58-68]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Uranium mining waste piles, heavily polluted with radionuclides and other toxic metals, are a reservoir for bacteria that have evolved special strategies to survive in these extreme environments. Understanding the mechanisms of bacterial adaptation may enable the development of novel bioremediation strategies and other technological applications. Cell isolates of Bacillus sphaericus JG-A12 from a uranium mining waste pile in Germany are able to accumulate high amounts of toxic metals such as U, Cu, Pb, Al, and Cd as well as precious metals. Some of these metals, i.e. U, Cu, Pd(II), Pt(II) and Au(III), are also bound by the highly orderd paracrystalline proteinaceous surface layer (S-layer) that envelopes the cells of this strain. These special capabilities of the cells and the S-layer proteins of B. sphaericus JG-A12 are highly interesting for the clean-up of uranium contaminated waste waters, for the recovery of precious metals from electronic wastes, and for the production of metal nanoclusters. The fabricated nanoparticles are promising for the development of novel catalysts. This work reviews the molecular biology of the S-layer of the strain JG-A12 and the S-layer dependent interactions of the bacterial cells with metals. It presents future perspectives for their application in bioremediation and nanotechnology.]]></dc:description>

<dc:date>2011</dc:date>
<dc:description><![CDATA[Removal of phenol under iron-carbon (Fe-C) microelectrolysis was enhanced by O2-microbubble. The removal rate (R0) of phenol reached 65% in 2 h. O2 bubbling plays a critical role, as compared to the air and N2 bubbling, in which only 9.5% and 4% of phenol is removed in 2 h, respectively. It shows that more dissolved oxygen in water is favorable for the oxidation process. Phenol removal is effective at lower temperature or/and higher dissolution pressure also confirms the role of dissolved oxygen. In the microbubble-assisted microelectrolysis system, O2, Fe-C pellets, and H2SO4 are the necessary conditions for the oxidation of phenol. The conversion of phenol follows the kinetics of the pseudo-first order, polynomially increases with the increasing amount of Fe-C pellets or/and sulfuric acid. Catechol, hydroquinone, and low molecular carboxylic acids are the major products.]]></dc:description>

<dc:description><![CDATA[The structure of a steam-water flow in a vertical pipe of 195.3 mm inner diameter was studied using novel wire-mesh sensors for high-pressure / high-temperature operation (max. 7 MPa / 286 °C). Tests were carried out at pressures of 1 and 2 MPa under nearly adiabatic conditions as well as with slightly sub-cooled water. The evolution of radial gas fraction profiles and bubble-size distributions along the pipe in a high-pressure steam-water flow was measured for the first time. The experimental data allow to correlate the intensity of steam condensation in contact with sub-cooled water with the structure of the interfacial area and the bubble size distribution, which is very important for the model development.]]></dc:description>

<dc:source><![CDATA[Physical Review B 72(2005), 054511]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Resistivity measurements have been performed on a low (LR)- and high (HR)-resistance variant of the κ-(BEDT-TTF)<sub>2</sub>Cu[N(CN)<sub>2</sub>]Br superconductor. While the HR sample was synthesized following the standard procedure, the LR crystal is a result of a somewhat modified synthesis route. Judging by their residual resistivities and residual resistivity ratios, the LR crystal is of distinctly superior quality. He-gas pressure was used to study the effect of hydrostatic pressure on the different transport regimes for both variants. The main results of these comparative investigations are (i) a significant part of the inelastic-scattering contribution, which causes the anomalous ρ(T) maximum in standard HR crystals around 90  K, is sample dependent, i.e., extrinsic in nature; (ii) the abrupt change in ρ(T) at T* ≈ 40  K from a strongly temperature-dependent behavior at T>T* to an only weakly T-dependent ρ(T) at T<T* is unaffected by this scattering contribution and thus marks an independent property, most likely a second-order phase transition, and (iii) both variants reveal a ρ(T) at T<T* is unaffected by this scattering contribution and thus marks an independent property, most likely a second-order phase transition, and (iii) both variants reveal a ρ(T) α AT<sup>2</sup> dependence at low temperatures, i.e., for T<sub>c</sub>≤T≤T<sub>0</sub>, although with strongly sample-dependent coefficients A and upper bounds for the T<sup>2</sup> behavior measured by T<sub>0</sub>. Provided that there are no differences in the Fermi surface between both variantsthe present experiments give no indications for such differencesthe latter result is inconsistent with the T<sup>2</sup> dependence originating from coherent Fermi-liquid excitations.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[We present a new mechanism for the scattering rate in the mixed state of layered superconductors. This mechanism acts through the modification of the layer-stacking factor which suppresses magnetic quantum oscillations if the interlayer electron hopping is incoherent. In the superconducting state, the interlayer incoherence restores and gives a negative contribution to the interlayer quasiparticle scattering rate. The mechanism may explain recent findings of enhanced magnetic quantum-oscillation amplitudes in the superconducting state of a layered organic conductor which displays an incoherent electronic transport across the layers.]]></dc:description>

<dc:description><![CDATA[The Master Curve (MC) approach of defining reference transition temperature, T0, has been standardized in ASTM Standard Test Method E 1921. This approach has been gaining acceptance in the codes for reactor pressure vessel (RPV) integrity assessment throughout the world. T0 is calculated from a data set of J-integral based fracture toughness values measured in the lower ductile-to-brittle transition region. This direct measurement approach is preferred over the correlative and indirect methods used in the past to assess irradiated RPV integrity. The basic MC approach for analysis of fracture test results is intended for macroscopically homogeneous steels with a body centred (ferritic) structure only. In reality, the steels in question are seldom fully macroscopically homogeneous.
The fracture toughness values measured on Charpy size SE(B) specimens of base metal from the Greifswald Unit 8 RPV show a large scatter. The basic MC evaluation following ASTM E1921 supplies a MC with many fracture toughness values which lie below the 1% fracture probability line. Thus, some inhomogeneity may still exist in the data set. In this paper, new comparatively simple extensions of the MC are applied on these fracture toughness data. The structural integrity assessment procedure SINTAP contains a lower tail modification of the MC analysis. A random estimation method describes the fracture toughness distribution following a Gaussian distribution with infinite quality steps oscillating around a normal distribution. With the application of the SINTAP modification and the random estimation higher reference temperatures were estimated in comparison to the basic MC approach according to ASTM E1921.]]></dc:description>

<dc:description><![CDATA[Ion implantation is a well-known standard procedure in electronic device technology for precise and controlled introduction of dopants into silicon. However, damage caused by implantation acts as effective gettering zones, collecting unwanted metal impurities. This effect can be applied for "proximity gettering reducing the concentration of impurities in the active device region. In this study the consequences of high-energy ion implantation into silicon and of subsequent annealing were analysed by means of secondary ion mass spectrometry (SIMS). Depth profiles were recorded of such impurities as copper, oxygen and carbon to obtain information about their gettering behaviour. The differences in impurities gettering behaviour were studied as a function of the implanted ions, P and Si, of the implantation dose and annealing time at T=900degreeC. Besides  impurities gettering at the mean projected range (Rp) of implanted ions, Rp-effect, defects at around half of the projected ion range, Rp/2-effect, and even in some cases beyond Rp, trans-Rp-effect, have also been found to be effective in gettering of material impurities.]]></dc:description>

<dc:description><![CDATA[500 keV nitrogen implantations at different tilt angles (0o, 0.5o, 1.2o, 1.6o, 4o) with respect to the c-axis of 6H-SiC were carried out. Radiation damage distributions have been investigated by Backscattering Spectrometry combined with channeling technique (BS/C) using 3550 keV 4He+ ion beam. A comparative simultaneous evaluation of the damage depth distributions in the Si and C sublattices of 6H-SiC led to a correction factor of 0.8 in the electronic stopping power of 4He+ ions along <0001> channel. Full-cascade Crystal-TRIM simulations with the same set of damage accumulation model parameters could reconstruct the measured shapes and heights of damage distributions for all implantation tilt angles. Secondary defect generation effects in addition to the primary point defect accumulation were assumed in the analysis.]]></dc:description>

The results show a clear sector formation of the affected loop at the downcomer, lower plenum and core inlet. The maximum local values of the relative temperature rise in the experiment amount 97.7% and in the calculation 97.3%]]></dc:description>

<dc:title><![CDATA[Some Aspects of Actinide Speciation by Laser Induced Spectroscopy]]></dc:title>
<dc:source><![CDATA[Coordination Chemistry Reviews 250(2006), 844-854]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Summary

During the past decade many studies on speciation of actinides in natural and artificial environments have been done. High demands on the sensitivity in speciation of actinides lead to the development of advanced detection methods. This is connected with intensive use of laser systems as excitation source. Laser can provide any wavelength from the near UV to the NIR (Near Infrared) wavelength range. The development of tunable solid-state lasers overcame some disadvantages of dye laser systems. The application of low temperatures for samples measured with fluorescence spectroscopic methods brought effort in the detection of carbonate species. The availability of modern femtosecond laser systems in combination with ICCD (Intensified Charge Coupled Device) cameras gave the possibility to exploit the fluorescence properties of aromatic organic compounds for the study of their interaction with actinides, especially non-fluorescent metal ions.
The fluorescence of some tetravalent actinides as Pa(IV) and U(IV) in aquatic systems was described firstly. The speciation of actinides in arsenate and several carbonate systems was investigated. The interaction with ligands from life sciences as ATP (adenosine triphosphate) and sugar phosphates became more and more important. Also studies of the speciation of actinides in plants and microorganism cannot be neglected.
In the solid state the speciation of uranium(VI) in several natural and synthetic minerals has been studied as well as the behaviour of depleted uranium in the environment. The interaction of actinides with rock materials and minerals as well as their uptake is also of common interest in actinide chemistry. Especially the sorption and inclusion of Cm into several minerals  lead to an improvement in knowledge of minor components in solids.
It is not possible to give a complete overview on the literature about the laser-induced spectroscopy of actinides. The restricted length of this contribution allows only a relatively small and personally influenced selection.]]></dc:description>

<dc:source><![CDATA[Bioconjugate Chemistry 16(2005)3, 660-668]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Mixed - ligand model complexes of general formula [Tc-99m(O)(kappa(3) -SPh)(kappa(1)-SPh))] [X = O (1a), S (2a)] were prepared in a one-step procedure from [(TcO4-)-Tc-99m] using stannous chloride as reducing agent. Stability studies and challenge experiments with glutathione showed that complex 2a presented promising features for pursuing animal studies. The activity in the brain (% dose injected/organ) at 5 min (0.14% +/- 0.03) and 120 min (0.11% +/- 0.02) pi encouraged the synthesis of several mixed-ligand "3 + 1" oxo complexes of general formula [M(O)(kappa(3)-PNS)(kappa(1)-SL))] (M = Tc-99m, 3a-6a, Re, 3-6), in which the tridentate ligand is the heterofunctionalized phosphine 2-(diphenylphosphanyl)-N-(2-thioethyl)benzamide (PNS) and the co-ligands are different arylpiperazine derivatives (HSL1-HSL4). The Tc-99m complexes have been characterized by comparison of their retention times in the HPLC chromatogram (gamma-detection) with the retention times of the analogous Re complexes (UV detection at 254 nm). The 99mTc complexes, obtained with radiochemical purity higher than 95%, after HPLC purification, are stable in saline, 0.01 M PBS (pH 7.4), rat plasma (4 h, 37 degrees C), and glutathione (10 mM solutions, 2h, 37 degrees C). Binding affinity and selectivity for 5-HT1A receptors (relative to the 5-HT2A receptor) were determined, complex 5 demonstrating the best values (IC50 for the 5-HT1A 2.35 +/- 0.02 nM; competitor 5-HT2A 372 +/- 11 nM). Biodistribution and stability studies in mice indicated a preferred hepatobiliary excretion, a high in vivo stability, but a poor brain uptake.]]></dc:description>

<dc:title><![CDATA[Einfluss von Wasserstoff auf die Zähigkeit von bestrahlten Reaktordruckbehälterstählen]]></dc:title>
<dc:source><![CDATA[55. Sitzung des RSK-Ausschusses Druckführende Komponenten und Werkstoffe, 05.-06.07.2005, Berlin, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Das Projekt liefert einen Beitrag zum Kenntnisstand der Wirkung von Bestrah-lung und Umgebungseinflüssen auf den Reaktordruckbehälter und dient zur Aufrechterhaltung eines hohen Sicherheitsstandards.  Bis heute ist der Me-chanismus der Versprödung von RDB-Stählen nicht vollständig verstanden. Gesichert ist die Wirkung des Neutronenfeldes auf die Zähigkeitsabnahme von RDB Stählen. Zunehmend wird aber ein synergistischer Effekt zwischen Wasserstoff und den durch Bestrahlung erzeugten nanodispersen Strukturde-fekten diskutiert. 
Ziel des Projektes war es eine experimentellen Nachweis über die Wechsel-wirkung von Wasserstoff und den bestrahlungsbedingten Strukturdefekten zu erbringen, den möglichen Einfluss auf die Zähigkeitsabnahme von RDB Stäh-len zu untersuchen und Unterschiede im Verhalten gegenüber dem unbe-strahlten Zustand auszuweisen.
Zur Untersuchung des Einflusses von Wasserstoff auf das Zähigkeitsverhal-ten von Reaktordruckbehälterstählen wurden einachsige Zugversuche bei verschiedenen Dehnraten an unbestrahlten und bestrahlten, wasserstoffvor- und in-situ beladenen Proben bei Raumtemperatur und 250°C durchgeführt. Die Bestimmung der mechanischen Eigenschaften wurde durch fraktografi-sche Untersuchungen der Bruchflächen ergänzt.
Mit SANS-Untersuchungen, der Analyse von Wasserstoffgehalten und Ther-modesorptions-untersuchungen wurde geprüft, ob Strahlendefekte als Haft-stellen für Wasserstoff wirksam werden. 
Es konnte gezeigt werden, dass die Empfindlichkeit gegenüber Wasserstoff-versprödung von der chemischen Zusammensetzung des RDB-Stahles, der Fluenz bis zu der bestrahlt wurde, der Bestrahlungstemperatur und der Art der gebildeten Strahlendefekte bestimmt wird. Eine verstärkte Anfälligkeit ge-genüber Wasserstoffversprödung wird bei RT, in-situ Wasserstoffbeladung und langsamen Dehnraten sowie geringen Bestrahlungstemperaturen beo-bachtet. Bei 250°C ist eine Versprödung durch Wasserstoff nicht mehr nach-weisbar. Aus den Ergebnissen ist abzuleiten, dass bestrahlungsinduzierte De-fekte keine bevorzugten Plätze für eine höhere Aufenthaltswahrscheinlichkeit für Wasserstoff unter Betriebstemperaturen von RDB darstellen. Sie sind so-mit keine internen Quellen für Wasserstoff. Bei Betriebstemperaturen ist des-halb nicht mit einer erhöhten Versprödungsanfälligkeit zur zu rechnen. Durch die höheren Festigkeiten der bestrahlten Stähle steigt aber allgemein die Empfindlichkeit gegenüber Wasserstoffversprödung.
Der Integritätsnachweis von RDBs außerhalb des Leistungsbetriebes unter Wasserstoffwirkung ist deshalb noch zu erbringen.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[We introduce a model of rotating magnetic field with a weak axial gradient which approximates the field generated by a slightly conical and sufficiently long inductor. The axial variation of the free-space field is assumed to be weak and its amplitude is approximated by the first linear term of expansion in a power series of the axial coordinate. This allows us to obtain an analytic solution for the azimuthal harmonics of the induced scalar electric potential and the azimuthal driving force in a cylinder of finite length. The results are verified by comparison with a numerical solution obtained by a Chebyshev-tau method.]]></dc:description>

<dc:description><![CDATA[This report collects selected outstanding scientific and technological results obtained within the frame of the European project FLASiC (Flash LAmp Supported Deposition of 3C-SiC) but also other work performed in adjacent fields. Goal of the project was the production of large-area epitaxial 3C-SiC layers grown on Si, where in an early stage of SiC deposition the SiC/Si interface is rigorously improved by energetic electromagnetic radiation from purpose-built flash lamp equipment developed at Forschungszentrum Rossendorf. Background of this work is the challenging task for areas like microelectronics, biotechnology, or biomedicine to meet the growing demands for high-quality electronic sensors to work at high temperatures and under extreme environmental conditions. First results in continuation of the project work  for example, the deposition of the topical semiconductor material zinc oxide (ZnO) on epitaxial 3C-SiC/Si layers  are reported too.]]></dc:description>

<dc:description><![CDATA[The paper contributes to the advanced CFD simulation of subcooled boiling in forced convective flows, with special attention given to the momentum transfer between continuous liquid and vapour bubbles. A wall boiling model, implemented in CFX-5 (Egorov, Menter, 2004) and based on the two-fluid approach, is used here together with the state-of-the-art model correlations for the non-drag forces, available in CFX-5. The paper describes the main concepts of modelling mass, heat and momentum transfer between the phases. Published experimental results for flow in a pipe are used for the model validation.
The model is applied to the simulation of subcooled boiling flow in a hot channel of a fuel rod bundle. Influence of mixing vanes, attached to the spacer grids of fuel assembly in order to enhance the heat transfer, is taken into account. The simulation results demonstrate the capability of the model to estimate the effects of geometrical design on the flow physics.]]></dc:description>

<dc:description><![CDATA[At the radiation source ELBE (Electron accelerator producing a quasi-continuous electron beam of high Brilliance and low Emittance) of the FZR a neutron source is being constructed. The electron beam with energies of up to 40 MeV and pulse frequencies of up to 13 MHz is converted into sub-ns neutron pulses by stopping the electrons in a heavy (high atomic number) radiator with a small volume. The neutrons are generated by bremsstrahlung photons through (gamma,n)-reactions. The energy deposition of the electron beam in the small neutron radiator is that high that any solid material would melt. Therefore, the neutron radiator consists of liquid lead flowing through a channel of 11.2×11.2 mm² cross section. From the thermal and mechanical point of view molybdenum turned out to be the most suited channel wall (thickness 0.5 mm) material. Depending on the electron energy and current up to 20 kW power will be deposited into a radiator volume of 3 cm³. This heating power is removed through the heat exchanger in the liquid lead circuit. Typical flow velocities of the lead are in the range of 2 m/s in the radiator section. The electrons escaping from the radiator and the secondary radiation are dumped to a large extent in an aluminum beam dump. To reduce the radiation background in the measuring direction, the neutrons are decoupled from the radiator at an angle of 90° with respect to the impinging electrons. 
Particle transport calculations were carried out to determine the volumetric heat generation in the liquid lead,  in the channel wall and in the Al beam dump. Subsequent fluiddynamic and thermo-mechanic finite element analyses are performed to proof the mechanical integrity of the radiator channel. It could be shown that the equivalent plastic strain of the radiator channel can be kept sufficiently small, i.e. less than 1 %. Thermal analyses of the water cooled Al beam dump proved, that the maximum temperatures do not exceed 200 °C, thus a sufficient distance from the melting point is maintained.]]></dc:description>

<dc:description><![CDATA[Ion implantation and subsequent thermal annealing are the standard processes for the electrical doping of semiconductors. Ion implantation is characterized by fast ballistic processes which lead to the deposition of the implanted atoms and to displacements of the target atoms. After the fast relaxation of the displaced atoms a (meta)stable defect structure is formed. Long-term thermally activated processes, especially during thermal annealing, cause defect reduction, rearrangement, and migration. In my talk I will show that computer simulations on the atomic level are a useful tool for the theoretical description of the  different physical processes occurring during ion implantation and thermal annealing. The ballistic processes are simulated by the Crystal-TRIM code which is based on the binary collision approximation (BCA). This code is part of different process simulators. Classical molecular dynamics (MD) simulations are employed to investigate defect migration over a period of  10 - 100 ns. The defect diffusivity as well as the microscopic migration mechanisms are studied.  A combination of BCA and MD simulations is used to determine the complex defect morphology after the fast relaxation processes are finished. This method allows the effective calculation of the total number and the depth distribution of different defect species (e.g. isolated vacancies and self-interstitials as well as more complex defects) formed on average per incident ion.]]></dc:description>

<dc:description><![CDATA[Für die Untersuchung von mehrphasigen Strömungen steht am Forschungszentrum Rossendorf eine Röntgenanlage mit einem zweidimensionalen Bildaufnehmer und einer eindimensionalen schnellen Detektorzeile zur Verfügung. In dieser Arbeit soll die Eignung dieser Anlage zur Bestimmung der lokalen Gasphasenverteilung in einem begasten chemischen Rührkesselreaktor, der aus der Verfahrenstechnik her bekannt ist, untersucht werden. Dazu wird zunächst die Signalcharakteristik des Aufnahmesystems untersucht, um die zu erwartende Genauigkeit der tomographischen Messung beurteilen zu können. Ein Algorithmus für die Rekonstruktion von zwei- und dreidimensionalen Projektionsdaten wurde implementiert. Mit einem Phantom wurde die quantitative Genauigkeit der Bestimmung zeitgemittelter Gaspahsenanteile überprüft. Zur Korrektur der Strahlaufhärtungsartefakte wurde eine Kalibriermethode entwickelt, mit der es möglich ist, die Gasphasenanteile direkt aus den bestimmten Schwächungskoeffizienten zu bestimmen. Es konnte gezeigt werden, dass die quantitative Genauigkeit der Kegelstrahl-Tomographie durch den hohen Anteil an Streustrahlung beeinträchtigt ist. Mit der schnellen Detektorzeile wurden schnell rotierende Objektstrukturen sichtbar gemacht.]]></dc:description>

<dc:description><![CDATA[The forced crucible rotation technique has been applied to the solidification of Nd-Fe-B alloys. Specially sealed samples were subjected to well-defined forced rotation during induction heating and solidification. The resulting microstructure of the Nd-Fe-B alloys in consideration of melt convection has been investigated using scanning electron probe microscopy. The determination of the α-Fe volume fraction by measuring the magnetic moment in a vibrating sample magnetometer (VSM) resulted in a distinct reduction of the α-Fe volume fraction in samples with high crucible rotation frequencies. Furthermore, a new category of experiment has been started where a tailored magnetic field was applied in order to study the microstructure evolution due to an enhancement or suppression of the melt convection by additional alternating magnetic fields.]]></dc:description>

<dc:description><![CDATA[It could be shown that dendritic compounds show the same complex stoichiometry in non-water and water soluble forms. The stability constants in both solution sytems are comparable. As a consequence this demonstrates the possible use of such compounds in for complexation of metal ions aquatic systems. 
As the fluorescence decay times change with the concentration of the added metal ion two effects have to be discussed: Dynamic fluorescence quenching, excited state reactions of the ligand. In case of dynamic fluorescence quenching a linear relationship between the concentration of the quencher and the ratio of the fluorescence decay time without and with quencher should be observed.]]></dc:description>

<dc:source><![CDATA[Steroids 73(2007), 69-76]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[In our effort to develop imaging agents for brain glucocorticoid receptors, we have prepared several novel glucocorticoids possessing a 2-methylsulfanyl-acetyl side chain. The synthesis was accomplished via a Mitsunobu reaction with thiobenzoic acid starting from cortisol, prednisolone, dexamethasone and triamcinolone acetonide to give the corresponding S-thiobenzoates in 75-82% yield. Subsequent saponification and reaction with methyl iodide afforded C-21 methylthioethers in 68-82% yield. All compounds were tested in an in vitro glucocorticoid receptor binding assay. Triamcinolone acetonide-based compound 12 showed promising binding affinity of 144% relative to dexamethasone (100%).
Compound 12 was selected for radiolabeling with the short-lived positron emitter carbon-11. The radiolabeling was carried out starting from S-thiobenzoate 8 and in situ formation of the corresponding sodium thiolate, which was further reacted with [<SUP>11</SUP>C]methyl iodide. The obtained radiochemical yield was 20-30%. The specific activity was determined to be 20-40 GBq/µmol at the end-of-synthesis, and the radiochemical purity exceeded 98%.]]></dc:description>

<dc:source><![CDATA[BAGECO-8, 26.-29.06.05, Lyon, Frankreich]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Interactions of U(VI) with the indigenous bacterial and archael communities of the uranium mining waste pile Johanngeorgestadt in Germany were studied. For this several portions of one sample with a natural content of 40 mg U/kg were supplemented with 60 mg U/kg and 260 mg U/kg in form of uranyl nitrate. Part of the most contaminated portion was additionally incubated under anaerobic conditions. Bothe, selective sequential extraction (SSE) and X-ray absorption spectroscopic analyses, indicated that added U(VI) was bound as uranyl by inner-sphere sorption complexes. No reduction of U(VI) to U(IV) was observed even by the anaerobic treatment.
Analyses of the constructed 16S rRNA gene clone libraries of the untreated and of the U(VI)-supplemented samples revealed changes in the bacterial and in the archaeal parts of the natural microbial community. In the untreated sample the bacterial community was predominated by Alphaproteobacteria and Holophaga/Acidobacterium members. The number of the latter was strongly reduced by increasing the uranium content up to 100 mg U/kg. Instead, a large number of sequences were found representing Gamma-Pseudomonas spp., Arthrobacter ssp. (Actinobacteria) as well as Geobacter spp. (Deltaproteobacteria). The most contaminated portion containing approximately 300 mg U/kg was predominated by represenatives of Cytophaga/Flavobacterium/Bacteroides group. The anaerobic treatment of this sample induced also proliferation of Alpha- and Gammaproteobacteria in it.
The archaeal populations in the original waste sample were rather diverse, whereas the supplemented with U samples wee strongly predominated by a few particular Grenarchaeota species.
Our results indicate that the addition of U(VI) to a low contaminated uranium mining waste sample induces significant shifting in the indigenous microbial populations in dependence on the amount of U(VI) and the redox conditions.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[Postulating an unlikely core melt down accident for a light water reactor (LWR), the possible failure mode of the reactor pressure vessel (RPV) and its failure time have to be investigated for a determination of the load conditions for subsequent containment analyses. Worldwide several experiments have been performed in this field accompanied with material properties evaluation, theoretical, and numerical work.
At the Institute of Safety Research of the FZR a finite element model (FEM) has been devel-oped simulating the thermal processes and the viscoplastic behaviour of the vessel wall. An advanced model for creep and material damage has been established and has been validated using experimental data. The thermal and the mechanical calculations are sequentially and recursively coupled. The model is capable of evaluating fracture time and fracture position of a vessel with an internally heated melt pool.
The model was applied to pre- and post test calculations for the FOREVER test series repre-senting the lower head RPV of a pressurized water reactor (PWR) in the geometrical scale of 1:10. These experiments were performed at the Royal Institute of Technology in Stockholm. In this paper the differences between the results of a simple coupled and a recursive coupled FE-simulation are highlighted. Due to the thermal expansion at the beginning and the accu-mulating creep strain later on the shape of the melt pool and of the vessel wall are changing. Despite of the fact that these relative small geometrical changes take place relatively slowly over time, the effect on the temperature field is rather significant concerning the mechanical material behavior and the resulting failure time. Assuming the same loading conditions, the change in the predicted failure time between the simple and the recursive coupled model is in the order of magnitude of the total failure time of the simple model. The comparison with results from the FOREVER-experiments shows that the recursive coupled model is closer to reality than the one-way coupled model.]]></dc:description>

<dc:description><![CDATA[The fluoroethyl ester-containing phenyltropane derivative MCL-322 was shown to display high affinity to the dopamine transporter (DAT) (Ki = 2.3 nM). The binding affinities (Ki values) for the serotonin transporter and norepinephrine transporter were determined to be 5.1 nM and 280 nM, respectively [1]. The high binding affinities and selectivities of MCL-322 make the corresponding 18F-labelled compound an attractive PET radioligand for imaging DAT in brain tissue.

<dc:description><![CDATA[The fluoroethyl ester-containing phenyltropane derivative MCL-322 was shown to display high affinity to the dopamine transporter (DAT) (Ki = 2.3 nM). The binding affinities (Ki values) for the serotonin transporter and norepinephrine transporter were determined to be 5.1 nM and 280 nM, respectively [1]. The high binding affinities and selectivities of MCL-322 make the corresponding 18F-labelled compound an attractive PET radioligand for imaging DAT in brain tissue. Here, we report on the radiosynthesis of [18F]MCL-322 and its radiopharmacological characterization involving biodistribution, autoradiography and small animal PET studies.]]></dc:description>

<dc:description><![CDATA[Force field parameters for the modeling of oxotechnetium(V) and oxorhenium(V) complexes with amine, amide, imine, carboxylate and thiolate donors have been derived and optimized with 131 published solid state structures. An automated procedure, based on a simplex algorithm, was used to optimize the 35 sets of metal-dependent structural parameters for each metal ion. These were introduced into the established MOMEC97 force field. The application of the new force field in the prediction of a novel radio-pharmaceuticals structure was successful; the predicted structures of the two isomers compared well with the corresponding crystal structures obtained (RMS around the metal core: 0.153 and 0.035 Å, respectively).]]></dc:description>

Die unbeabsichtigte Verringerung der Borkonzentration, die sog.

<dc:description><![CDATA[Multigap Resistive Plate Chambers (MRPC) provide the possibility for assembling high-granularity, large-area TOF sytems designed for modern nuclear and particle physics experiments. Currently, experiments like ALICE, STAR, FOPI, HADES prepare MRCP based TOF systems with time resolutions of less than 100 ps. The planned CBM experiment at the future FAIR facility at GSI/Darmstadt considers using an MRPC system provided sufficient time resolution and rate stability can be achieved. These properties of MRCP have been successfully demonstrated in prototype tests performed at the FZD electron linac ELBE, using continuous e− beams of 20-40 MeV. Typical time resolutions of 70 ps were achieved. The rate capabilities of MRCP using special low-resistive silicate glas were tested and stable efficiencies up to rates of 20 kHz/cm2 were observed.]]></dc:description>

<dc:description><![CDATA[Trigonal-bipyramidal Re(III) complexes with tetra-dentate/monodetate NS3/P 4+1-coordination are inter-esting agents for the development of rhenium-188 com-plexes for potential therapeutic application. In order to understand relationships between the structure of rhenium-188 4+1 complexes and their in vitro stability we synthesized a series of rhenium model complexes 1, 2 and determined their stability in human plasma. 
The complexes were prepared as described in [1] using various combinations of NS3 derivatives and mono-dentate phosphorus(III) ligands. 
Since instability in aqueous solution always leads to the formation of perrhenate, we determined the amount of perrhenate formed after 1h, 24 h and 48 by TLC. 
By means of physico-chemical parameters of the corres-ponding non-radioactive rhenium complexes we tried to find factors which may govern the formation of complexes showing high in vitro stability. 
Finally, the most stable representative 3 was studied in 188Re labeling experiments with a phosphine-arginine-tyrosine model conjugate using the water-soluble N-hydroxysulfosuccinimidyl ester of the monodentate phosphine.]]></dc:description>

<dc:description><![CDATA[A new facility for the production of polarised bremsstrahlung has been built at the superconducting electron accelerator ELBE of the Forschungszentrum Rossendorf. The bremsstrahlung facility and the setup for photon-scattering experiments are designed such that the background radiation due to scattering of photons and production of neutrons is minimised. The sensitive setup in connection with electron energies up to 20 MeV and average currents up to 1 mA delivered by the ELBE accelerator enables novel experiments using photon-induced reactions. First results of photon-scattering experiments are presented.]]></dc:description>

<dc:description><![CDATA[The emission of K+ and ± mesons has been studied in the asymmetric collision system Au+C and in the inverse reaction C+Au at 1.0A GeV (and at 1.8A GeV for C+Au only) in order to extract the effective source rapidities based on their distribution in the pt-y plane. The extracted source rapidity of K+ mesons is about ys/ybeam=0.25 at both incident energies [y(Au)=0,y(C)=ybeam]. This corresponds to a reaction volume consisting of the C nucleus and a tube cut out of the Au nucleus. In clear contrast, the source rapidities of ± mesons vary from ys/ybeam=0.5 in peripheral collisions (corresponding to NN interactions) to about ys/ybeam<0.33 in central reactions. The multiplicities of K+ and  are compared to symmetric collision systems and, together with detailed transport model calculations, are used to study the sensitivity to the nuclear equation of state.]]></dc:description>

<dc:description><![CDATA[The influence of density differences on the mixing of the primary loop inventory and the Emergency Core Cooling (ECC) water in the downcomer of a Pressurized Water Reactor (PWR) was analysed at the ROssendorf COolant Mixing (ROCOM) test facility. ROCOM is a 1:5 scaled model of a German PWR, and has been designed for coolant mixing studies. It is equipped with advanced instrumentation, which delivers high-resolution information for temperature or Boron concentration fields.

An experiment with 5 % of the design flow rate in one loop and 10 % density difference between the ECC and loop water was selected for validation of the CFD software packages CFX-5 and Trio_U. Two similar meshes with approximately two million control volumes were used for the calculations. The effects of turbulence on the mean flow were modelled with a Reynolds stress turbulence model in CFX-5 and LES approach in Trio_U. CFX-5 is a commercial code package offered from ANSYS Inc. and Trio_U is a single-phase CFD tool which is developed by the CEA-Grenoble, France.

The results of the experiment and of the numerical calculations show that mixing is dominated by buoyancy effects: At higher mass flow rates (close to nominal conditions) the injected slug propagates in the circumferential direction around the core barrel. Buoyancy effects reduce this propagation. The ECC water falls in an almost vertical path and reaches the lower down¬comer sen¬sor directly below the inlet nozzle. Therefore, density effects play an important role during natural convection with ECC injection in PWRs. Both CFD codes were able to predict the observed flow patterns and mixing phenomena quite well.]]></dc:description>

<dc:description><![CDATA[In this work we present a method to study the energy of the phonon modes responsible for nonradiative energy relaxation of electrons in the active zone of quantum cascade lasers (QCLs). The method is based on the analysis of the oscillations pattern of QCLs emission intensity as a function of magnetic field applied along the growth direction. We studied first GaAs/AlGaAs QCLs with different Al concentration in the barriers (33% and 45%). We demonstrated that in the case of high Al concentration the relaxation via AlAs- like LO phonon can be significant. We have also shown that in case of In0.73Ga0.27As/AlAs short-wavelength QCL in spite of the high Al concentration in the barriers and the low GaAs contents in the wells, the nonradiative energy relaxation happens principally via GaAs-like or InAs-like (or mixed modes) phonon emission, while a clear signature of AlAs-like phonons was not observed.]]></dc:description>

<dc:description><![CDATA[Messungen mit leitfähigkeitsbasierter Nadelsondensysteme sind gängige Messverfahren für hochtransiente Zweiphasenströmungen. Leitfähigkeits-Nadelsonden eignen sich jedoch nicht zur Untersuchung nichtleitender Fluide bzw. Mehrphasenströmungen. Um dieses Problem zu behandeln, kann die kombinierte Leitfähigkeits- und Permittivitäts- bzw. Kompleximpedanzmessung eingesetzt werden. Dafür wird in diesem Beitrag eine Impedanznadelsonde und eine dazugehörige Messelektronik vorgestellt. Erste vielversprechende Ergebnisse von Messungen an ausgewählten organischen Fluiden werden dargestellt und diskutiert.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[In order to investigate the relation between shape anisotropy and unidirectional anisotropy in exchange biased lines, the magnetic domain configuration during magnetization reversal was studied as a function of the ratio between both anisotropy contributions. For that purpose a number of glass / Ta 7nm / PtMn 20nm / CoFe 4nm / Ta 4nm samples were sputter deposited. By means of either optical lithography and physical etching or focus ion beam (FIB) milling several line pattern in the range between 0.5 and 2.5 µm width and 20 µm length have been prepared. In order to modify the ratio between both anisotropy contributions the exchange bias field strength was reduced by means of 5 keV He+ ion irradiation. The domain structure during magnetization reversal was then investigated by means of magnetic force microscopy. For the as-prepared samples a mono-domain magnetization state with the magnetization direction aligned along the exchange bias field direction was found regardless of its shape. After irradiation, i. e., reduction of the unidirectional anisotropy, the situation has changed completely. The homogeneous magnetization state broke up into small domains with 360° domain walls in between. The appearance of these domain walls was only observed for the descending branch of the magnetization reversal. In addition it was found that the number of domain walls created depends strongly on the stripe width and orientation.]]></dc:description>

<dc:description><![CDATA[The magnetic-field dependence of the operation of a quantum-cascade intersubband laser (QCL) is used to investigate the energetic relaxation of injected electrons through phonon emission. The QCL emits at 3.8mkm and incorporates a strain-compensated active region with a large degree of internal strain. Energies of the relevant electron-phonon scattering responsible for the depopulation of the upper laser level are determined from the analysis of the Landau-level spectra. A comparison of those energies with the Raman spectrum of the active region is used to identify which phonon is primarily involved in the electron-phonon scattering. In spite of the low Ga-content in the (In,Ga)As quantum wells and high Al-content in the AlAs/ (In,Al)As composite barriers, the depopulation of the upper laser level appears to be dominated by the resonant electron-GaAs-likelongitudinal-phonon intersubband scattering. In particular, the contribution due to AlAs-like modes is negligible]]></dc:description>

<dc:description><![CDATA[Magnetic fields provide an attractive contact-less influence on the motion of metallic or semiconductor melts and the related heat and mass transfer. An optimal design of the magnetic field is often difficult due to the lack of experimental access to the velocity field in such opaque melts. Several recently developed measuring techniques will be presented which allow an almost complete velocity resolution in metallic melts up to temperatures of about 400C. On this basis a combination of cold liquid metal model experiments with numerical simulations represents a powerful approach. Various examples will be presented ranging from crystal growth, aluminum investment casting to liquid metal two-phase flows. For the electromagnetic levitation process results will be given on sample instabilities and active means for stabilization as well as the flow field inside a molten sample.]]></dc:description>

<dc:title><![CDATA[The application of FIB from mass separated alloy LMIS]]></dc:title>
<dc:source><![CDATA[nanoFIB 2005 - Advances in Focused Ion Beam Microscopy, 15.04.2005, Oxford, UK]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[During the last decades, the focused ion beam (FIB) became a very useful and versatile tool in the microelectronics industry, as well as in the field of research and development. For special purposes like writing ion implantation or ion mixing in the µm- or sub-µm range ion species other than gallium are needed. Therefore alloy liquid metal ion sources (LMIS) were developed. The energy distribution of the ions from an alloy LMIS is one of the determining factors for the performance of a FIB column. Different source materials like Au73Ge27, Au82Si18, Au77Ge14Si9, Co36Nd64, Er69Ni31, and Er70Fe22Ni5Cr3 were investigated with respect to the energy spread of the different ion species as a function of emission current, ion mass  and emitter temperature. The alloy LMIS`s discussed above have been used for writing implantation to fabricate sub-µm pattern without any lithographic steps. A Co-FIB is applied for the ion beam synthesis of CoSi2 micro-structures down to 30 nm. Furthermore, a broad spectrum of ions was employed to study the sputtering process depending on temperature, angle of incidence and ion mass on a couple of target materials. Especially this direct patterning was used for the fabrication of various kinds of micro-tools as well as recently for nano-holes in AFM cantilever tips.
Running and future activities will be discussed which are focused to the preparation and investigation of plasmonic structures, like nano-wires and nano-chains in the sub-micron scale down to a few ten nanometers. 		]]></dc:description>

<dc:source><![CDATA[Journal of Applied Physics 97(2005)12, 124906]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The effect of flux and Ar pretreatment during ion beam nitriding of austenitic stainless steel is investigated. The ion energy and temperature were 1.2 keV and 400°C, respectively, the ion current densities were 0.5, 0.67, and 0.83 mA∙cm-2. The nitrogen distribution profiles were measured using nuclear reaction analysis. The obtained nitrogen distribution profiles were analyzed by the means of the nitrided layer thickness evolution due to sputtering and diffusion and the model of trapping-detrapping. Both approaches could fit well the experimental results, however different diffusion coefficients have to be assumed for each current density. In addition, the diffusion coefficients are higher for higher current densities. On the other hand, it is shown that the pretreatment with Ar ion beam at nitriding temperatures produces only a thermal effect without any other influence on the following nitrogen diffusion. The results are discussed in relation with surface and temperature effects and atomic transport mechanisms.]]></dc:description>

<dc:description><![CDATA[The prenyl group is known as an important structural building block in natural and medicinal products. The isotopic substitution of one of the two methyl groups with a [11C]methyl group would provide an access to a large number of interesting 11C-labelled compounds. Here we report a strategy for the synthesis of 11C-labelled prenyl group-containing derivatives starting from methyl-substituted alkynes (1) via a novel 11C-C bond forming reaction. A commonly employed strategy to form a,a-disubstituted alkenes comprises the formation of alkenylzirconocenes by the syn-insertion of a C-C triple bond into the Zr-H bond of Schwartz reagent [Cp2Zr(H)Cl] followed by metal-mediated C-C bond formation with electrophiles under retention of the configuration of the C-C douple bond [1,2]. 
In principle the formation of alkenylzirconocenes by syn-addition of Schwartz reagent onto disubstituted alkynes (1) leads to a mixture of regioisomers 2 and 2. However, treatment of an excess of Schwartz reagent favors the formation of the sterically less hindered isomer 2.

<dc:description><![CDATA[The production of K+ and of K- mesons in heavy-ion collisions at beam energies of 1 to 2 A GeV has systematically been investigated with the kaon spectrometer KaoS. The ratio of the K+ production excitation function for Au+Au and for C+C reactions increases with decreasing beam energy, which is expected for a soft nuclear equation-of-state. A comprehensive study of the K+ and of the K- emission as a function of the size of the collision system, of the collision centrality, of the kaon energy, and of the polar emission angle has been performed. The K-/K+ ratio is found to be nearly constant as a function of the collision centrality and can be explained by the dominance of strangeness exchange. On the other hand, the spectral slopes and the polar emission patterns are different for K- and for K+. Furthermore the azimuthal distribution of the particle emission has been investigated. K+ mesons and pions are emitted preferentially perpendicular to the reaction plane as well in Au+Au as in Ni+Ni collisions. In contrast for K- mesons in Ni+Ni reactions an in-plane flow was observed for the first time at these incident energies.]]></dc:description>

<dc:description><![CDATA[We investigate different kinds of electro-vortex flows generated in a shallow layer of liquid metal. The metal flow is driven by an externally applied electrical current which interacts with its own magnetic field. Due to symmetry this interaction alone causes not yet a flow as the Lorentz force is purely irrotational. If, however, ferromagnetic C-cores or yokes are applied, the magnetic field distribution is modified and a flow driving action results. An electro-vortex flow occurs with several eddies in this MHD-layer. In the stable case, for some range of electrical current values, these eddies are held in permanent position. The unstable case is characterized by an oscillation of the eddies, which are moving in the plane of the layer. One of the reasons to perform this study is related with the occurrence of similar unstable processes in some devices used for metallurgical purposes including the flat MHD-layer considered here. We have investigated this flow by experimental and numerical methods.
We applied the ultrasound Doppler velocimetry which allows us to measure velocity profiles in non-transparent media. The oxide particles of this alloy were acting as good tracers for ultrasound measurements and allowed us to obtain the time-dependences of the velocity profiles. At higher electrical currents, the profiles showed large-scale low-frequency oscillations. Various types of flows are distinguished depending on the location of the ferromagnetic C-core.
The mathematical model of the processes was based on the MHD-equations, which have been modified using a thin-layer approximation. The numerical calculations support the results obtained in experiments, and showed the behavior of the velocity field with the moving of the eddies.]]></dc:description>

<dc:description><![CDATA[As an effort to improve the corrosion behavior of the mild steel under work conditions, we attempted to produce a high chromium content layer on its surface by applying the recoil implantation process. After polishing, SAE 1020 construction steel samples were covered with chromium and then bombarded with ions. As recoil bombarding atom, we used nitrogen, a light mass specimen. Recoil atoms were applied either by ion beam (IB) accelerator or by plasma immersion ion implantation (PIII) method. Samples treated by the PIII process showed better results, presenting a thicker layer of high Cr content, as measured by Auger electron spectroscopy (AES).]]></dc:description>

<dc:title><![CDATA[Formation of Highly Mobile Di-Interstitials During Ion Implantation]]></dc:title>
<dc:source><![CDATA[E-MRS 2005 Spring Meeting, 31.05.-03.06.2005, Strasbourg, France]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Atomistic computer simulations show that the metastable defect structure formed immediately after ion bombardment of silicon does not only consist of isolated mono-vacancies and mono-interstitials but also of more complex defects. Amongst them a small percentage of very mobile di-interstitials is found. The structure and energetics of these defects as well as their migration are investigated in more detail, and the results are compared with literature data. Mobile and immobile di-interstitial configurations are found. The migration mechanism shows a pronounced dependence on the temperature. The di-interstitial diffusivity and the self-diffusion coefficient per defect are calculated. The di-interstitial migrates much faster than the mono-interstitial.
The high mobility of the di-interstitials and the fact that they can be already formed during the ion bombardment may have implications for the current understanding of many experimental results obtained in the last decade, in particular for the explanation of the implantation-induced migration of interstitial-like defects at room temperature.]]></dc:description>

<dc:date>2011</dc:date>
<dc:description><![CDATA[The conversion of ZnO into a p-type semiconductor remains a major challenge for its application in optoelectronic devices, since up to now neither the suitable type of defects nor the possible role of secondary phase formation during doping has been clarified. Here, the implantation of arsenic into epitaxial ZnO thin films on Alpha-Al<SUB>2</SUB>O<SUB>3</SUB> (0001) and subsequent isothermal annealing in high vacuum are studied by particle induced X-ray emission, X-ray diffraction, transmission electron microscopy, and Raman spectroscopy. The as-implanted ZnO:As films are single phase and exhibit a locally disordered ZnO lattice structure. Zn<SUB>3</SUB>As<SUB>2</SUB> nanocrystals segregate at 700°C. Due to annealing at 800°C, Alpha-As and Alpha-As<SUB>2</SUB>O<SUB>3</SUB> are formed. The study demonstrates the role of solid state reactions and secondary phase formation for group V element doping of ZnO that is a promising route to convert this material into a p-type semiconductor.]]></dc:description>

<dc:date>2010</dc:date>
<dc:description><![CDATA[Abstract. We have analyzed the transport of hot electrons generated in the interaction between a short-pulse, ultra-high intensity laser beam (pulse duration t<ps, intensity Il2 >1018 W.cm-2.μm2) and a solid or dense target through the use of proton emission imaging. We used targets of different material (Cu, Al, Au) with a regularly modulated rear target surface in order to compare the electron transport in different conditions. As result, we see that the electron transport depends on the target material and on the interaction conditions.]]></dc:description>

<dc:title><![CDATA[Optimization of induction heating for container-less melt extraction from a metallic sheet]]></dc:title>
<dc:source><![CDATA[Metallurgical and Materials Transactions B 41(2010), 1074-1083]]></dc:source>
<dc:date>2010</dc:date>
<dc:description><![CDATA[This work examines the induction heating of a metal sheet to be used for multiple instance melt extraction from the lower edge. The task formulation of heating the edge in first place while keeping the release of Joule heat along that edge as homogeneous as possible, i.e., the avoidance of end effects, is solved numerically with a parametric study. A set of factors is also modeled physically in the framework of an experimental series. Subject to variation are (1) the extension of the copper block, which simulates the extraction wheel, in both directions parallel and perpendicular to the inductor; (2) the protrusion depth of the edge of the sheet below the lower face of the inductor; and (3) the shape of the inductor. It is shown that this shape adopted from the floating zone crystal growth technique in a previous work,[1] albeit acting effectively, is removed from optimum. In this article, a more efficient solution is proposed. The numerical simulations also suggest that the vertical position of the inductor must be significantly above that one in Reference 1 to increase the efficiency of the process. Reasonable conformity may be stated between the calculated and the experimental results.]]></dc:description>

<dc:description><![CDATA[The preliminary results on charged pion production in np collisions at an incident beam energy of 1.25 GeV measured with HADES are presented. The np reactions were isolated in dp collisions at 1.25 GeV/u using the Forward Wall hodoscope, which allowed to register spectator protons. The results for np -> pppi-, np -> nppi+pi- and np -> dpi+pi- channels are compared with OPE calculations. A reasonable agreement between experimental results and the predictions of the OPE+OBE model is observed.]]></dc:description>

<dc:source><![CDATA[Nuclear Engineering and Design 237(2007), 497-508]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[The structure of a steam-water flow in a vertical pipe of 195.3 mm inner diameter was studied using novel wire-mesh sensors for high-pressure / high-temperature operation (max. 7 MPa / 286 °C). Tests were carried out at pressures of 1 and 2 MPa under nearly adiabatic conditions as well as with slightly sub-cooled water. Steam was injected into sub-cooled water and condensed during the upwards flow. The evolution of radial gas fraction profiles and bubble-size distributions along the pipe in a high-pressure steam-water flow was measured for the first time. The experimental data allow correlating the intensity of steam condensation in contact with sub-cooled water with the structure of the interfacial area and the bubble size distribution, which is very important for the model development. The data were used to test the complex interaction of local bubble distributions, bubble size distributions and local heat and mass transfer. The model considers a large number of bubble classes (50). This allows the investigation of the influence of the bubble size distribution. The results of the simulations show a good agreement with the experimental data. The condensation process is clearly slower, if the injection nozzle diameter is increased  (from 1 to 4 mm orifices). Also bubble break-up has a strong influence on the condensation process because of the change of the interfacial area. Some modelling errors arises from the uncertainty of the interfacial area for large bubbles and the heat transfer coefficient.]]></dc:description>

<dc:title><![CDATA[Microstructure and non-basal plane growth of epitaxial MAX phase Ti2AlN thin films]]></dc:title>
<dc:source><![CDATA[Journal of Applied Physics 99(2006), 34902]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Thin films of the MAX phase Ti2AlN were epitaxially grown onto single crystal MgO(111) and MgO(100) substrates by DC reactive magnetron co sputtering from Ti and Al targets in an Ar/N2 gas mixture at a temperature of 690 °C. To promote the nucleation of the MAX phase, an fcc (Ti0.63Al0.37)N seed layer was deposited before changing to Ti2AlN growth parameters. The nucleation processes have been studied by real time in situ specular x ray reflectivity. Independent of substrate orientation, the seed layer shows no roughening until its final thickness of approximately 100 Å indicating pseudomorphic layer by layer growth within the descriptive step-flow growth model of Kodambaka et al. [1]. The MAX phase shows heteroepitaxial layer by layer growth on MgO(111), with increased surface roughening up to approximately 200 Å, whereas on MgO(100) the growth mode changes to Volmer Weber type already after three monolayers. X ray scattering in Bragg Brentano geometry of the final, approximately 1000 Å thick, Ti2AlN film reveals lattice parameters of c = 13.463 Å and a = 2.976 Å on the MgO(111) substrate and c = 13.740 Å and a = 2.224 Å on the MgO(100) substrate. From ex situ pole figure measurements the epitaxial relationship between film and substrate lattice was determined to be MgO{111}<110> // Ti2AlN{101‾2}<1‾21‾0>, regardless of the substrate orientation. This tilted, non basal plane growth leads to a threefold grain orientation of Ti2AlN along the MgO<110> directions and a polycrystalline morphology, which is also confirmed by cross sectional transmission electron microscopy. The growth can be assumed to take place in a step-flow mode, i.e. emerging steps on the high surface free energy (0001) plane where adatoms come to rest after diffusion along A-facets, irrespective of epitaxial relationship.]]></dc:description>

<dc:description><![CDATA[This contribution aims at introducing a new multiscale, multicomponent CFD/CMFD approach for the simulation of thermal-hydraulics flows evolving in complex component-scale configurations. In this novel approach, the flow system could involve one or two fluids, convective and conductive heat transfer in solids, and phase-change heat transfer. This is made possible thanks to the Immersed Surfaces Technology (IST), a methods inspired from Interface Tracking techniques for two-phase flow, whereby solid bodies contained in the system are defined using a solid level set function to describe their surfaces, transcending conventional unstructured and body-fitted grids (BFC). In a typical two-phase flow, material properties of the fluids and the solid are segregated based on the gas-liquid and solid Level-Set functions. The technique helps solve conjugate heat transfer problems without resorting to explicit jump conditions. Selected validation test-cases are presented here.

<dc:description><![CDATA[Bakterielle Hüllproteine, sogenannte S-Layer, bilden eine intelligente Grenzschicht zwischen Zellen und ihrer Umwelt. Diese erlauben es Bakterien auf Uranabfallhalden, giftige Schwermetalle am Eindringen in die Zelle zu hindern, während lebensnotwendige Spuren¬elemente die Barriere passieren können. Verantwortlich für die genannte Eigenschaft ist eine gitterförmige und hochgeordnete Ausprägung des Proteinpolymers und damit verbunden eine regelmäßige und definierte Anordnung zahlreicher funktioneller Gruppen auf der Polymeroberfläche. Letztere ist ursächlich für die selektive Bindung bestimmter Metalle. Darüber hinaus bilden S-Layer-Proteine spontan monolagige Schichten an Grenzflächen und auf Oberflächen. Diese Kombination von Eigenschaften machen S-Layer sehr interessant für die Entwicklung neuer Biokompositwerkstoffe für technische Anwendungen und insbe¬sondere für die Wasserbehandlung. Zur Beschichtung und Funktionalisierung technischer Träger mit S-Layern werden Layer-by-Layer-Techniken genutzt. Derartige Biokomposite dienen gegenwärtig der Entwicklung von selektiven Filtern, von Biosensoren und von Fotokatalysatoren zur Detektion und Entfernung von anorganischen sowie organischen Schadstoffen aus Wasser.]]></dc:description>

<dc:source><![CDATA[Flow Measurement and Instrumentation 17(2006), 1-11]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[A measuring system based on potential difference probes is presented which makes possible the determination of very small values of the velocity in liquid metal flows. On the one hand, a large size of the sensor and a high induction of the static measuring field, respectively, and resolution on the other hand has always been a compromise. These opposite demands were countered with state of the art analog instrumentation, and by avoiding meticulously potential sources of error such as induced noise and the even more detrimental thermoelectricity. The present paper instances the flow driven by a rotating magnetic field, in which the scaling of velocity versus strength of the driving electromagnetic force was examined. The measurement of the transition from the Stokes regime to a laminar boundary one demonstrates the obtained improvement of the velocity resolution by about two orders of magnitude.]]></dc:description>

<dc:description><![CDATA[The Traveling Magnetic Field (TMF) is a versatile tool to control the flow in an electrically conducting fluid. It introduces a mainly axial Lorentz force into the fluid which leads to meridional flow patterns. Applying the TMF to the Vertical Gradient Freeze (VGF) growth of semiconductor single crystals, the heat and mass transport in the melt can be tailored for growth under optimised flow conditions to improve crystal properties and/or growth yield.
In this paper we present experimental and numerical results on the TMF driven flow in an isothermal model fluid as well as in a VGF melt. The field is created by an equally spaced set-up of six coils of 36 windings each. Induction and frequency can be varied between 0-5 mT and 50-400 Hz, respectively. 
Model experiments were carried out at about 20°C with the traveling field applied to InGaSn melts in cylindrical, non-conducting vessels of different diameters. Axial velocity profiles were measured by means of the Ultrasonic Doppler Velocimetry (UDV) method. The basic flow was investigated as a function of the aspect ratio and of the non-dimensional forcing and screening parameters with the focus on the transition from laminar to time-dependent convection. For comparison, numerical calculations were performed using advanced, highly accurate spectral methods as well as commercial codes. 
For the growth experiments a VGF furnace was equipped with the TMF set-up. The maximum temperature of the furnace is about 1300°C and crystals with a diameter up to three inches can be grown. Ga doped germanium single crystals were grown under the influence of the field and without field. The TMF impact on the thermal field in the melt was studied on the basis of natural or artificially induced dopant striations which characterise the solid-liquid interface and, thus, the local temperature field. The transition to instationary melt flow which is indicated by the appearance of regular striation patterns in the crystal, was investigated by increasing the TMF forcing parameter intentionally during growth. Numerical results came from a quasi-2D simulation of the melt flow using the commercial code CrysVun++. A global, thermal model of the VGF furnace has been developed for this purpose.]]></dc:description>

<dc:description><![CDATA[Experimental data obtained at the TOPFLOW facility for steam-water vertical pipe flow were used to test the complex interaction of local bubble distributions, bubble size distributions and local heat and mass transfer. Steam is injected into sub-cooled water and condenses during the upwards flow. The model considers a large number of bubble classes (50). This allows the investigation of the influence of the bubble size distribution. The results of the simulations show a good agreement with the experimental data. The condensation process clearly depends on the initial bubble size. Also bubble break-up has a strong influence on the condensation process because of the change of the interfacial area.]]></dc:description>

<dc:description><![CDATA[Since high-k insulators appear more and more to be preferable to SiO2 in semiconductor technology, Ge is again becoming of increasing interest, since its carrier mobility is higher than that of Si. Atomistic simulations are a powerful tool to investigate atomic-level physics and to get a better understanding of the processes during the technological steps in integrated electronic device manufacturing. 
In the present work different interatomic potentials for Ge are evaluated with respect to their accuracy in describing the structure and energetics as well as the migration of point defects. A number of parameterizations of the Stillinger-Weber (SW) potential and one Tersoff type potential were tested. 
The formation energies for different configurations of the interstitial are calculated. Also the formation energy of the vacancy and the bond defect are estimated. It can be shown that the extended 110-dumbbell configuration is the interstitial with the lowest formation energy for most SW parameter sets. In the Tersoff case the tetrahedral interstitial shows the lowest formation energy. For the SW-type potentials the vacancy shows a strong inward-distortion, whereas for the Tersoff potential it shows a slight outwards-distortion.
In recent ab-initio calculations the 110 dumbbell has been found to be the most stable interstitial structure. This is in qualitative agreement with the results for most SW parameter sets, although these calculations predict the extended dumbbell configuration as the interstitial with the lowest formation energy. For the SW parameter sets of W. Yu (model B) and Nordlund, the formation energy of this dumbbell is also in qualitative agreement with the ab-initio result. The formation energy of the vacancy obtained with these SW parameter sets is nearly equal to the ab-initio result. The observed inwards relaxation of the atoms around the vacancy is also found by ab-initio calculations.  However, the details of the lattice distortion near the vacancy and the interstitial differ from those predicted by ab-initio calculations.
For the reasons mentioned above, the SW parameter sets of Nordlund et al. and W. Yu et al. are selected for migration investigations. In both cases the vacancy mobility strongly dominates interstitial mobility. Some investigations are also performed with the Tersoff potential, where the vacancy shows a very low mobility.
The results are used to estimate the self-diffusion coefficient. With the SW approach it is shown that self-diffusion in Ge is mediated by vacancies. This stands in good agreement with experimental data. However, the calculated migration energy (2.2 eV) is less than the measured value (3.09 eV). With the Tersoff potential an interstitial dominated mechanism is found. Therefore the Tersoff potential cannot be considered useful for a study of point defect and self-diffusion in Ge.]]></dc:description>

<dc:description><![CDATA[Ni-Ti thin films as-sputtered are amorphous if the substrate is not intentionally heated during deposition. Therefore, these films have to be heat-treated to induce crystallization in order to exhibit the shape memory effect. Several films have been prepared by dc magnetron sputtering and then studied concerning the influence of the type of substrate (single crystal Si, polycrystalline Si) on the crystallization kinetics and the final structure. The structural development of the films during crystallization (at a constant temperature of 430°C) has been studied by X-ray diffraction in grazing incidence geometry (GID) off-plane at a synchrotron radiation beamline. These experiments allow to establish a correlation between the deposition conditions and the kinetics of crystallization. For films deposited at an electrode distance of 70 mm on a Si(100) substrate, a longer crystallization time is needed compared with films obtained at 40 mm, for otherwise fixed deposition parameters. The analysis of the nucleation kinetics by using the Kolmogorov-Johson-Mehl-Avrami equation lead to exponents between 2.6 and 3. The presence of an intermediate layer of poly-Si drastically enhances the crystallization process. Additionally, ex-situ annealing of identical samples at 500°C during 1 hour and complementary characterization of the structure and morphology of the films by Cross-sectional Transmission Electron Microscopy (XTEM) and Selected Area Electron Diffraction (SAED) were performed. The temperature dependence of the electrical resistivity was measured, identifying the phase transformation temperature ranges. An increase of the overall resistivity with the precipitation of Ni4Ti3 has been detected. Results obtained by X-ray reflectometry (XRR) and GID suggest that during crystallization excess nickel is driven into an amorphous region ahead of the crystal/amorphous interface, thus leading to a higher concentration of Ni at the surface and further precipitation of Ni4Ti3. t the shape memory effect.

<dc:description><![CDATA[The paper report about spatial dynamics studies of the Molten Salt Reactors (MSR). MSR is one of the concepts considered within the 'Generation IV International Forum'.  The graphite-moderated channel type MSR based on the previous Oak Ridge National Laboratory (ORNL) research is considered. 
The physical models and numerical solution procedures used in the dynamics code DYN3D-MSR are described. The most relevant peculiarities in MSR dynamics are the delayed neutrons precursors drift with the flowing fuel and the direct release of fission energy into the fuel-coolant salt. The code is based on the in-house developed code DYN3D for Light Water Reactor, which solves two-group neutron diffusion equations by the help of a nodal expansion method. The same method for prompt neutron kinetics is used in DYN3D-MSR, but the appropriate models for the delayed neutrons and for the thermal-hydraulic have been integrated.
The code has been validated against experimental data gained from the Molten Salt Reactor Experiment (MSRE), performed in the ORNL. After successful validation, the code DYN3D-MSR was applied to the analysis of several hypothetical transients typical for liquid fuel systems. Particularly, a prompt reactivity insertion modeling a control rod ejection accident was analyzed. By performing these analyses, the DYN3D-MSR code has been shown to be an effective tool for MSR dynamics studies.]]></dc:description>

<dc:source><![CDATA[Magnetism and Magnetic Materials Conference, 30.10.-03.11.2005, San Jose, USA]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Due to the high uniaxial anisotropy L10-ordered FePt is currently the most favoured candidate for future high density storage applications. However, in order to achieve the L10-phase either the deposition or post deposition annealing at temperatures above typically 500°C is required. Many attempts ranging from alternating monolayer deposition [1], different seed or cap layers [2] or doping with third elements [3] have been tried to reduce the ordering temperature with various degree of success.
Here we report on the L10-ordering of stoichiometric 30-125 nm thick FePt films which have been magnetron co-sputtered from elemental targets on SiO2/Si substrates with a deposition rate of (0.30-0.2) Å/s at various temperatures. Surprisingly, already for a deposition at 350°C the films are well chemically ordered in the tetragonal L10 structure with a long- range order parameter S=0.8-0.9 which has been determined by grazing incidence X-ray diffraction. The films exhibit a polycrystalline fiber texture with mean grain sizes of 12-18 nm and a random orientation distribution confirmed by pole figures measurements. In contrast, FePt films deposited at room temperature exhibit the fcc A1-phase with a mean grain size of (5.0 - 0.5) nm. In a sequence of annealing steps with successively increased temperatures, the A1 - L10 transition has been obtained between 300-400°C. After annealing at 400°C the films show nearly complete L10 ordering with S values equivalent to the films deposited at 350°C. During annealing the mean grain size grows to 10-12 nm. Using textured seed layers L10 ordered FePt films with preferred orientation can be realized. One of the key issues in observing the L10-ordering already at rather low temperatures is a combination of low deposition rate and low-energy ion irradiation during deposition.

<dc:description><![CDATA[Coherent spin waves in exchange biased bilayers have been excited by ultrafast photomodulation of the exchange bias anisotropy. Vector and time resolved Kerr effect was employed to trace the trajectory of the magnetization vector of the ferromagnetic layer in real time on the picosecond timescale. Photoinduced easy axis precession in CoFe/IrMn samples with different IrMn thicknesses, thus, different exchange bias fields, has been studied. The antiferromagnetic thickness dependence of the decay rate of the induced precession was investigated as a measure of the effective magnetic damping in the system. 
The observed increase of the extracted effective damping parameter is proportional to the square of the exchange bias field. Two-magnon scattering of the coherent spin precession of the ferromagnetic layer at local interfacial fluctuations of the exchange bias field can account for an additional dissipation mechanism. The two-magnon damping field in exchange bias systems is proportional to the square of the exchange bias field.

<dc:source><![CDATA[International Journal of Modern Physics A 20(2005)2-3, 427-435]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The production of vector mesons in collisions between nucleons is studied in order to address a variety of issues concerning nucleon-nucleon interaction, reaction mechanism and properties of baryons. These studies are summarized with emphasis on the most recent experiments at the Time-of-Flight spectrometer TOF and results obtained at the COoler SYnchrotron COSY in Jülich. While currently the open questions regarding the so-called OZI violation, its relation to the meson exchange picture and the relative importance of contributions to the production mechanism from various channels within this formalism are still unresolved, the present-day experiments hold the potential to clarify the situation greatly. Possible extensions of the experimental program on vector mesons using 4π detection techniques for charged as well as neutral particles, in particular π0, are discussed.]]></dc:description>

<dc:title><![CDATA[Small-angle neutron scattering and rate theory applied to neutron-irradiation-induced clustering of defects and copper atoms in iron]]></dc:title>
<dc:source><![CDATA[Micromechanics and Microstructure Evolution: Modeling Simulation and Experiments, 12.-16.09.2005, Madrid, Spain]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Results of small-angle neutron scattering (SANS) experiments are presented for a low-Cu (0.015 wt%) and a high-Cu (0.42 wt%) iron-based model alloy as well as selected reactor pressure vessel (RPV) steels. In order to exclude a strong participation of nickel atoms in the cluster formation, the selection of RPV steels is restricted to either low Ni content or low Cu in connection with medium Ni content according to the present status of knowledge. These materials were irradiated at about the RPV service temperature up to two or more levels of neutron fluence each. A low-temperature irradiation (60°C) is also included. The results are analysed in terms of both measured cluster size distribution and ratio of magnetic and nuclear contributions to SANS intensities. The assumptions underlying the analysis (e. g. spherical vs. plane scatterers) are addressed.  

Calculations are based on the direct solution of the master equation of rate theory for three special cases: (1) Long-term evolution of vacancy clusters (VCs) in the absence of copper atoms, (2) long-term evolution of copper clusters in the absence of vacancies but assuming irradiation-enhanced copper diffusion to occur, and (3) co-clustering of copper and vacancies. Assumptions and limitations are discussed and the results are compared with SANS results. 

It turned out that pure VCs or pure copper clusters were never observed. The observations for the low-Cu model alloy and the high-Cu model alloy can be interpreted as being due to spherical vacancy-rich clusters and Cu-rich clusters, respectively. The mean radius is about 1 nm in both cases. The parameters of the rate theory models can be adjusted so as to correctly reflect some major observations. The remaining discrepancies are also discussed.]]></dc:description>

<dc:source><![CDATA[Joint 15th Riga and 6th PAMIR International Conference on Fundamental and Applied MHD, 27.06.-01.07.2005, Jurmala, Latvia]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The phenomenon of sudden and irregular reversals of the Earth's magnetic field has attracted much interest in the last decades. It is known that the mean reversal rate varies from approximately zero in the Permian and Cretaceous supercrons to approximately 5 per Myr in the present. There is some observational evidence for the facts that the reversals are asymmetric in time and that the overall distribution of the field intensity has a bimodal behaviour. In an attempt to explain these features in a paradigmatic model we investigate a mean-field dynamo model of the alpha^2 type. Field saturation is guaranteed by alpha-quenching, and the influence of noise is taken into account. In order  to keep the model simple and to allow for very long simulations, we choose the helical turbulence parameter alpha as spherically symmetric. We show that reversals occur in the vicinity of so-called exceptional points of the spectrum of the dynamo operator, where two real eigenvalues coalesce and continue as a pair of complex conjugate eigenvalues. We describe the reversal  mechanism, and all the above mentioned features, in terms of a self-accelerating field  decay, followed by the rapid recovery of the field with opposite polarity. We point out that the reversal mechanism can be attributed to the square-root character of exceptional points in the spectrum. Hence it is not restricted to our particular model but should be identifiable also in more realistic models of the Earth dynamo.]]></dc:description>

<dc:description><![CDATA[In Analogie zu den Systemen für die KKW Saporoshje und Rovno wurden für die drei Blöcke des KKW Südukraine und für den ersten Block des KKW Chmelnitzky technische Systeme zur verbesserten betrieblichen Überwachung eingerichtet. Dazu werden der Aufsichtsbehörde vor Ort und im Krisenzentrum in Kiew einmal pro Minute für jeden Block bis zu 51 sicherheitsrelevante technologische und 16 radiologische Parameter zur Bewertung mittels moderner technischer Ausrüstungen online zur Verfügung gestellt. Die entwickelte Auswertesoftware gestattet die Darstellung der Bewertungsergebnisse in Form von Tabellen, Grafiken und Schemata. Außerdem ermöglicht ein Archivmodus Trendanalysen.
Mit der Integration der für die geschützte Warte gelieferten Ausrüstungen in das am Standort des KKW Saporoshje betriebene Fernüberwachungssystem ist es nunmehr möglich, die wesentlichen sicherheitsrelevanten Parameter des gesamten Standortes auch bei außergewöhnlichen Ereignissen mit Hilfe moderner Technik zu erfassen und zu bewerten.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Intersubband optical transitions at short wavelengths in strain-compensated In0.70Ga0.30AsAlAs double quantum wells are investigated by means of mid-infrared absorption. Trade-offs between achieving a high transition energy and a large oscillator strength of the two highest-energy intersubband transitions using our strain-compensation approach are analyzed as a function of the widths of the two wells. Two design strategies leading to relatively strong intersubband optical transitions at 800 meV, 1.55  µm, are described and the corresponding structures grown using gas-source molecular-beam epitaxy on (001)InP are investigated. The strongest intersubband transitions obtained experimentally are generally between 300 and 600 meV, 24  µm. Significant oscillator strength, however, also extends out to 800 meV, 1.55  µm.]]></dc:description>

<dc:title><![CDATA[Control of properties and structure of ZnO thin films by a wide variation of oxygenpressure during reactive magnetron deposition and by post-deposition annealing]]></dc:title>
<dc:source><![CDATA[European Materials Research Society Spring Meeting (E-MRS), Symposium G: ZnO and related materials, 31.05.-03.06.2005, Strasbourg, France]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Due to recent progress in crystal growth and unique optical and electrical properties ZnO becomes a prospective material for use in optoelectronic devices. ZnO thin films have been prepared at unheated glass substrates by reactive DC magnetron sputtering. The oxygen fraction in Ar + O2 gas mixture was varied from 0 to approximately 83%. The films have been characterized by spectroscopic ellipsometry (SE), atomic force microscopy (AFM) and X-ray diffraction (XRD). The dielectric function of ZnO layers was parameterized using Drude-Lorentz oscillator. As shown by SE, the dielectric functions of the films prepared at low oxygen fraction are characteristic for cermet materials (mixture of oxide and metal particles). XRD confirms the presence of both ZnO and metallic Zn phases in these films. The layers produced at high oxygen fractions (above 60%) are insulating and their dielectric functions can be reasonably described by Lorentz oscillator alone. Importantly, that the latter films are polycrystalline with pronounced (002) type texture even at a thickness of only 50 nm. The XRD results point to a high mechanical stress in these films that can be related to the bombardment by negative oxygen ions during the film growth.
ZnO films prepared at medium oxygen fraction of 48% were annealed in vacuum at about 340 °C for 1.5 hour with in situ control of optical properties by SE and resistivity by two point probe measurement. The influence of the structural ordering during annealing on the refractive index is higher than the free electron density variation. An enhancement of the film resistivity at the final annealing stage (last 40 min) with concomitant decrease of the free electron concentration could be an indication of the acceptor-like defect formation.]]></dc:description>

Vorversuche fanden bereits an einem horizontalen Luft/Wasser-Strömungskanal bei Atmosphärendruck statt. Es wurden optische Messungen mit einer Hochgeschwindigkeits-Kamera durchgeführt, die durch synchronisierte dynamische Druckmessungen ergänzt wurden. Außerdem wurden Geschwindigkeitsfelder in einem Schwall mit PIV (Particle Image Velocimetry) gemessen.
Zur Validierung des Codes CFX-5 wurden Nachrechnungen durchgeführt. Diese stimmten mit dem Experiment qualitativ gut überein. Zudem wurde eine Vorrausrechnung zum Heißstrang-Modell gezeigt.]]></dc:description>

<dc:title><![CDATA[Atomistic study of copper-vacancy clusters in bcc-Fe]]></dc:title>
<dc:source><![CDATA[5th Forum on New Materials, 14.-18.06.2010, Montecatini Terme, Italy]]></dc:source>

<dc:description><![CDATA[Copper-rich precipitates are assumed to be the main cause of hardening and embrittlement of Cu-bearing reactor pressure vessel steels since they act as obstacles to dislocation motion within the grains of polycrystalline bcc-Fe. Multiscale modeling contributes to a better understanding of point-defect-induced formation of these clusters during reactor operation. Rate theory is an efficient tool to simulate the cluster evolution on realistic time and length scales. However, many parameters used in rate theory, such as the diffusion coefficients of mobile species and the free binding energies of clusters, are not very well known from experimental investigations. Atomic-level computer simulations can provide these data. 
In the present work the free binding energies are determined for small and medium-sized CunVm clusters in bcc-Fe. The most recent Fe-Cu interatomic potential by Pasianot and Malerba [1] is used. Enthalpy and entropy contributions are calculated using combinations of on-lattice Monte Carlo simulations and off-lattice molecular dynamics calculations.

<dc:description><![CDATA[Ge (100) surfaces were irradiated by heavy Bi<sup>+</sup> and Bi<sup>++</sup> ions extracted from a Bi-liquid metal ion source in a mass separated focused ion beam system with energy of 30 and 60 keV, respectively. Networks of different nanoporous (or sponge like) structures were found depending on ion energy, fluence, angle of incidence and irradiation temperature. The porous and amorphous surface structures are explained in terms of high concentration vacancies close to the surface. The surface modification was investigated using SEM and AFM imaging and FIB for cross section preparation.]]></dc:description>

<dc:description><![CDATA[A superconducting rf photo electron injector (SRF gun) is under development at the Forschungszentrum Rossendorf. The project aims at several issues: improvement of the beam quality for the ELBE superconducting electron linac, demonstration of feasibility of this gun type, investigation of critical components, and parameter studies for future application (BESSY-FEL, 4GLS). In 2005, a substantial progress has been made. The two 3.5-cell niobium cavities for the gun have been delivered from the company ACCEL. The main parts for gun cryostat like vacuum vessel, cryogenic and magnetic shields are ready. Test benches for the cathode cooling system and the cavity tuner are being assembled. The photo cathode preparation lab has been arranged, and the diagnostic beam line has been designed (see T. Kamps et al., this conference).

<dc:description><![CDATA[Strontium titanate (STO) is a preferred substrate material for functional oxide growth, whose surface properties can be adjusted through the presence of RuddlesdenPopper (RP) phases. Here, density functional theory (DFT) is used to model the (1 0 0) and (0 0 1) surfaces of SrO(SrTiO3)n RP phases. Relaxed surface structures, electronic properties and stability relations have been determined. In contrast to pure STO, the near-surface SrOOSr stacking fault can be employed to control surface roughness by adjusting SrO and TiO2 surface rumpling, to stabilize SrO termination in an SrO-rich surrounding or to increase the band gap in the case of TiO2 termination. RP thin films have been epitaxially grown on (0 0 1) STO substrates by chemical solution deposition. In agreement with DFT results, the fraction of particular RP phases n = 13 changes with varying heating rate and molar ratio Sr:Ti. This is discussed in terms of bulk formation energy.]]></dc:description>

<dc:source><![CDATA[Acta Physica Slovaca 54(2004)4, 375-384]]></dc:source>
<dc:date>2004</dc:date>
<dc:description><![CDATA[The HADES spectrometer installed at GSI Darmstadt is devoted to the study of the production of di-lepton pairs from vector meson decays in relativistic nucleus-nucleus collisions, as well as proton- and pion-induced reactions. Extraction of rare lepton pairs in high hadron multiplicity events requires an efficient particle identification (PID). In HADES charged particles momentum is measured by a tracking system surrounding the toroidal super conducting magnet, and velocity and energy loss is provided by a TOF detector. Leptons are identified by a Rich as well as a Shower detector. The particle identification method is using full experimental information from all subdetectors. To demonstrate the method performance, single particle spectra of charged hadrons and leptons from C+C at 2 AGeV will be presented and compared with results of corresponding simulations. The proton and pion yields an m_T and rapidity distributions will be compared with existing data. Very preliminary results of lepton analysis will be shown as well.]]></dc:description>

<dc:title><![CDATA[Thermodynamics of Sorption Modeling: Advanced Concepts, Databases and Applicability Tests]]></dc:title>
<dc:source><![CDATA[Seminar, 13.05.2005, Poccatello (Idaho), United States]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The lecture summarizes efforts to deliver a chemical base for safety analysis and risk assessment. One major aspect is the substitution of conventional distribution coefficients (Kd values) for the empirical description of sorption processes by surface complexation models (SCM). 
The general strategy and examples for current blind predictive capabilities of SCM and the respective database RES<sup>3</sup>T  the "Rossendorf Expert System for Surface and Sorption Thermodynamics"- are explained. 
RES³T is a digitized version of a thermodynamic sorption database as required for the parametrisation of SCM, namely in risk assessment studies. 
The approach for the compilation of numerical data includes the collection of the mineral surface characteristics, the selection of reliable data records, the extrapolation to infinite dilution, the normalization to a reference site density and the averaging of selected thermodynamic data records.
The Cu(II) sorption onto goethite and the Np(V) sorption onto hematite were chosen as systems illustrating the blind predictive capabilities. The model predictions represent the experimental values for the adsorbed amount of Cu(II) and Np(V), respectively, expressed as conventional distribution coefficients K<sub>D</sub> as required by most performance assessment software, are within one order of magnitude or better.
As an example to illustrate the effect of parameter uncertainty in blind predictions the Np(V) sorption onto haematite was selected. The formally large scatter of pK values as extracted from literature is actually not critical. Even the use of inconsistent values from other electrostatic models will yield similar results. 
We can conclude, that for well-defined mineral systems, provided a suitable database is accessible, the SCM approach seems to be promising. More realistic (thermodynamic) approaches can and have to amend the K<sub>D</sub> concept.]]></dc:description>

<dc:description><![CDATA[The spectra of self-adjoint operators in Krein spaces are known to possess real sectors as well as sectors of pair-wise complex conjugate eigenvalues. Transitions from one spectral sector to the other are a rather generic feature and they usually occur at exceptional points of square root branching type. For certain parameter configurations two or more such exceptional points may happen to coalesce and to form a higher order branch point. We study the coalescence of two square root branch points semi-analytically for a PT-symmetric  4×4 matrix toy model and illustrate numerically its occurrence in the spectrum of the 2×2 operator matrix of the magnetohydrodynamic α²-dynamo and of an extended version of the hydrodynamic Squire equation.]]></dc:description>

<dc:description><![CDATA[We discuss the coaxial power input in normal and superconducting RF (SRF) photoinjector cavities.  Upstream coaxial power input has been previously used at the PITZ facility where the output beam tube is an intrinsic part of the coaxial transmission line into the gun.  In this paper, we describe coaxial coupling from the cathode side of the gun.  For normal conducting RF guns, in addition to the advantage from symmetric coupling, an emittance compensation solenoid can now be positioned close to the gun cavity to deliver optimal transverse emittance.  Beam dynamics calculations demonstrate 0.8 mm-mrad at 1 nC in X-band.  For an SRF gun, we present a design for coaxial input around the cathode using a superconducting coupling cell. This cell matches the external quality factor of the gun for different beam powers and there is no RF loss associated with the axial gap of the cathode.  The heat input into the coaxial feed and the surface field of the coupler are discussed.  For a 1.3 GHz half-cell gun cavity with stored energy of 6.6 J, a 2.5 MeV electron beam can be delivered with a peak accelerating field of 50 MV/m. At 10 mA, the external Q is 2.1 x 106 and the coaxial line power loss that must be cooled is 28 W.]]></dc:description>

<dc:source><![CDATA[Wissenschaftlich-Technische Berichte / Helmholtz-Zentrum Dresden-Rossendorf; FZR-431 2005<br>ISSN: 1437-322X]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The flow distribution in the primary circuit of the pressurized water reactor was studied with experiments and Computational Fluid Dynamics (CFD) simulations. The main focus was on the flow field and mixing in the downcomer of the pressure vessel: how the different factors like the orientation of operating loops, the total loop flow rate and the asymmetry of the loop flow rates affect the outcome. In addition to the flow field studies the overall applicability of CFD methods for primary circuit thermal-hydraulic analysis was evaluated based on the CFD simulations of the mixing experiments of the ROCOM (Rossendorf Coolant Mixing Model) test facility and the mixing experiments of the Paks NPP.
The experimental part of the work in work package 3 included series of steady state mixing experiments with the ROCOM test facility and the publication of results of Paks VVER-440 NPP thermal mixing experiments. The ROCOM test facility models a 4-loop KONVOI type reactor. In the steady-state mixing experiments the velocity field in the downcomer was measured using laser Doppler anemometry and the concentration of the tracer solution fed from one loop was measured at the downcomer and at the core inlet plane. The varied parameters were the number and orientation of the operating loops, the total flow rate and the (asymmetric) flow rate of individual loops. 
The Paks NPP thermal mixing experiments took place during commissioning tests of replaced steam generator safety valves in 1987-1989. It was assumed that in the reactor vessels of Paks VVER-440 NPP equipped with six loops the mixing of the coolant is not ideal. For the realistic determination of the active core inlet temperature field for the transients and accidents associated with different level temperature asymmetry a set of mixing factors were determined. Based on data from the online core monitoring system and a separate mathematical model the mixing factors for loop flows at the core inlet were determined.

In the numerical simulation part of the work package 3 the detailed measurements of ROCOM tests were used for the validation of CFD methods for primary circuit studies. The selected steady state mixing experiments were simulated with CFD codes CFX-4, CFX-5 and FLUENT. The velocity field in the downcomer and the mixing of the scalar were compared between CFD simulations and experiments. The CFD simulations of full scale PWR included the simulation of Paks VVER-440 mixing experiment and the simulation of Loviisa VVER-440 downcomer flow field. In the simulations of Paks experiments the experimental and simulated concentration field at the core inlet were compared and conclusions made concerning the results overall and the VVER-440 specific geometry modelling aspects like how to model the perforated elliptic bottom plate and what is the effect of the cold leg bends to the flow field entering to the downcomer. With Loviisa simulations the qualitative comparison was made against the original commissioning experiments but the emphasis was on the CFD method validation and testing.

The overall conclusion concerning the CFD modelling of the flow field and mixing in the PWR primary circuit could be that the current computation capacity and physical models also in commercial codes is beginning to be sufficient for simulations giving reliable and useful results for many real primary circuit applications. However the misuse of CFD methods is easy, and the general as well as the nuclear power specific modelling guidelines should be followed when the CFD simulations are made.

The numerical grid model was generated with the grid generator IC4C (ICEM-CFD) and the preprocessor CFX-5 and contains 4.7 Mio. tetrahedral elements. The output of the Best Practice Guidelines for optimizing the numerical studies in different reactor types was used in the numerical simulation. Data from a coupled code calculation with DYN3D/ATHLET were used as inlet boundary conditions. 4 different Mixing Scalars were utilized to obtain information about the contribution of each loop during the transient. The results show a clear sector formation of the affected loops at the downcomer and core inlet. At the beginning of the start-up of loop 3 the sectors of loop 1,2,4 cover a bigger area.]]></dc:description>

<dc:description><![CDATA[A new facility for the production of polarised bremsstrahlung has been built at the superconducting electron accelerator ELBE of the Forschungszentrum Rossendorf. The bremsstrahlung facility and the detector setup are designed such that the background radiation due to scattering of photons and production of neutrons is minimised allowing for experiments close to and above particle separation energies in nuclei. 
First results of photon-scattering and photo-dissociation experiments on {92,98,100}Mo are presented.

<dc:description><![CDATA[A research program has been started to study  experimentally  the near-threshold photodissociation of nuclides in the chain of cosmic heavy element production with bremsstrahlung from the ELBE accelerator. An important prerequisite for such studies is  good knowledge of the bremsstrahlung distribution which was determined by measuring the photodissociation of the deuteron and by comparison with model calculations. First data were obtained for the astrophysically important target nucleus 92-Mo by observing the radioactive decay of the nuclides produced by bremsstrahlung irradiation at end-point energies between 11.8 and 14.0 MeV. The results are compared to recent statistical model calculations.]]></dc:description>

<dc:source><![CDATA[Nuclear Physics in Astrophysics-II, 16.-20.05.2005, Debrecen, Hungary]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[A research program has been started to study  experimentally  the near-threshold photodissociation of nuclides in the chain of cosmic heavy element production with bremsstrahlung from the ELBE accelerator. An important prerequisite for such studies is  good knowledge of the bremsstrahlung distribution which was determined by measuring the photodissociation of the deuteron and by comparison with model calculations. First data were obtained for the astrophysically important target nucleus 92-Mo by observing the radioactive decay of the nuclides produced by bremsstrahlung irradiation at end-point energies between 11.8 and 14.0 MeV. The results are compared to recent statistical model calculations.]]></dc:description>

<dc:source><![CDATA[Journal of Magnetism and Magnetic Materials 311(2007), 489-493]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[The thermal expansion a has been measured for single-crystalline HoNi2B2C in the range between 2 and 200 K. At low temperatures, a is dominated by magnetic contributions leading to a strongly anisotropic behaviour with different signs for the expansion coefficients near the antiferromagnetic phase transition. Analysing the magnetic and lattice contributions of a well above this temperature, a nearly isotropic behaviour of the latter one can be deduced. Using the Ehrenfest relation, a relatively weak pressure dependence of the superconducting transition temperature of dTc=dp ¼ 0:1K=GPa was determined for pressure applied along the c direction which points to a rather small pressure-induced lattice stiffening. The ratio between expansion coefficient and specific-heat features large values at the onset of magnetic order.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[A ring of helical vortices is a common feature of the onset of thermal convective instability in a rapidly rotating spherical shell as expected in the Earth's core. In fact, there are good reasons that this kind of fluid motion plays an important role in the generation of earth's magnetic field. On the other hand, this ring of rolls can also result from a spherical Taylor-Couette instability as expected to be reproduced in a sodium experiment in Grenoble, France. In this work, the mean electromotive force (e.m.f) for such kind of flow structure is derived analytically following the lines of the mean field concept. The main idea is to split the basic mechanisms that could generate the dynamo action at large scale. Some numerical examples are also calculated.]]></dc:description>

<dc:description><![CDATA[Three rotational bands in 74 Kr were studied up to (in one case one transition short of ) the maximum spin Imax of their respective single-particle configuratio ns. Their lifetimes have been determined using the Doppler-shift attenuation method. The deduced transition quadrupole moments reveal a modest decrease, but far  from a complete loss of collectivity at the maximum spin Imax . This feature, together with the results of mean field calculations, indicates that the observed  bands do not terminate at I=Imax .]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[The picosecond dynamics of electrons in a doped GaAs/AlGaAs superlattice have been investigated by pump-probe experiments using an infrared free-electron laser. We observe a fast bleaching of the interminiband absorption followed by thermalization and a slower cooling component. The latter can lead to a positive or negative transmission change, resulting from the temperature dependence of the linear absorption spectrum at the respective wavelength. We show that the superlattice in contrast to quantum wells provides a unique picosecond thermometer for the electron temperature based on the dependence of the absorption on the electron distribution function.]]></dc:description>

<dc:source><![CDATA[Radiochimica Acta 93(2005)11, 699-703]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In order to better understand the mechanisms of actinide uptake by specific biomolecules, it is essential to explore the intramolecular interactions between the cation and the protein binding site. Although this has long been done for widely investigated transition metals, very few studies have been devoted to complexation mechanisms of actinides by active chelation sites of metalloproteins. In this field, X-ray absorption spectroscopy has been extensively used as a structural and electronic metal cation probe. The two examples that are presented here are related to two metalloproteins in charge of iron transport and storage in eukaryote cells: transferrin and ferritin. U(VI)O-2(2+),
Np(IV) and Pu(IV) have been selected because of their possible role as contaminant from the geosphere.]]></dc:description>

<dc:description><![CDATA[The superconducting electron accelerator ELBE at Rossendorf delivers electron beams of energies up to 20 MeV with average currents up to 1 mA for experiments using photon-induced reactions. The bremsstrahlung facility installed at this accelerator and the experimental area were designed such that the production of neutrons and the scattering of photons from surrounding materials is strongly reduced.
We have investigated the nuclides {92}Mo, {98}Mo, {100}Mo and {88}Sr in photon-scattering experiments at electron energies from 6 to 13 MeV. Several hundred dipole transitions were observed in each of the nuclides. The experimental dipole-strength distributions of the nuclei are compared with calculations on the basis of a quasiparticle-random-phase approximation for deformed nuclei. Statistical approaches to the correction of level feeding and decay branches are presented.
We have studied the {92}Mo(\gamma,n), {92}Mo(\gamma,p) and {92}Mo(\gamma,\alpha) reactions at various electron energies via photoactivation experiments. The deduced activation yields are compared with theoretical predictions.]]></dc:description>

<dc:description><![CDATA[For the first time flashing-induced out-of-phase oscillations are observed in a natural circulation loop operated at low pressure. Both regular (symmetric) and irregular oscillations patterns have been found. Simulations with the best-estimate thermal-hydraulic code ATHLET (developed by GRS, Germany) have been performed to get deeper insight in the phenomenology of the instability.
The main characteristics of the flow oscillations are illustrated and the relation between fluid travelling time and oscillation period is studied.]]></dc:description>

<dc:description><![CDATA[The economy of existent NPP designs suffers for the complexity of the safety systems (which have to be redundant and diversified). Nuclear reactors can be made more competitive and reliable by adopting a simpler design and passive safety systems. Following this philosophy, the design of natural-circulation BWRs was developed. In this type of reactors the coolant circulation is gravity-driven and is ensured as long as heat is produced in the core (if a sufficient water level is maintained) without the need of any active system. The elimination of the recirculation systems (pumps and related piping and components) simplifies the design and excludes a whole  series of  transients and initiating events that can lead to accidents (pump trips, LOCAs due to failures of the recirculation piping, etc.). Unfortunately, natural circulation systems may exhibit thermal-hydraulic instabilities under low-power and low-pressure conditions. Hence, appropriate start-up procedures have to be planned in order to avoid flow oscillations. In the paper strategies for the start-up of natural circulation BWRs are discussed.]]></dc:description>

The elimination of the recirculation systems (pumps and related piping and components) simplifies the design and excludes a whole  series of  transients and initiating events that can lead to accidents (pump trips, LOCAs due to failures of the recirculation piping, etc.). Unfortunately, natural circulation systems may exhibit thermal-hydraulic instabilities under low-power and low-pressure conditions. Hence, appropriate start-up procedures have to be planned in order to avoid flow oscillations. In the paper strategies for the start-up of natural circulation BWRs are discussed.]]></dc:description>

<dc:description><![CDATA[The β-decay of 102Sn was studied by using high-resolution germanium detectors as well as a Total Absorption Spectrometer (TAS). A decay scheme has been constructed based on the γ-γ coincidence data. The total experimental Gamow-Teller strength BGTexp of 102Sn was deduced from the TAS data to be 4.2(9). A search for β-delayed γ-rays of 100Sn decay remained unsuccessful. However, a Gamow-Teller hindrance factor h = 2.2(3), and a cross-section of about 3nb for the production of 100Sn in fusion-evaporation reaction between 58Ni beam and 50Cr target have been estimated from the data on heavier tin isotopes. The estimated hindrance factor is similar to the values derived for lower shell nuclei.]]></dc:description>

<dc:description><![CDATA[In der vorliegenden Arbeit wurde das Transportverhalten von U(VI) bei der Migration durch Quarz und Gibbsit untersucht. Experimentell erfolgte diese Untersuchung in Säulenversuchen unter ungesättigten Bedingungen. In die Betrachtung wurden 3 Säulen mit unterschiedlichen Quarz- und Gibbsit- Anteilen einbezogen. (Säule 1: Quarz, Säule 2: Gibbsit/Quarz = 1/10, Säule 3: Gibbsit/Quarz = 1/4) 
Die aufgebrachte Kontaminationslösung hatte eine Urankonzentration von 5 x 10-6 mol/L. Aus den Ergebnissen der Kationenanalyse des Eluats konnte eine Durchbruchskurve des Urans aufgezeichnet werden. Im Rahmen dieser Arbeit erfolgte jedoch nur ein Durchbruch des Urans in der Quarzsäule. Das Geomaterial der Säule 1 (Quarz) und der Säule 3 (Gibbsit/Quarz: 1/4) wurde im Anschluss an die Sorptionsuntersuchung in Scheiben a 0,5 cm geschnitten. Nach einem Säureaufschluss erfolgte die Bestimmung der Urankonzentration in den einzelnen Scheiben. Im Ergebnis erkennt man, dass die Retardierung des Urans durch zwei Prozesse erfolgte: Adsorption an der Mineraloberfläche und Präzipitation einer Festphase. Der zweite Teil dieser Arbeit beinhaltete die Vorausberechnung der U(VI)-Migration durch die Säulen mit Hilfe des Programms MCOTAC. Diese Berechnung erfolgte für die Quarzsäule und es zeigte sich eine gute Übereinstimmung der Ergebnisse aus Experiment und Modellierung.]]></dc:description>

<dc:description><![CDATA[Photoconductive emitters are an attractive way for impulsive generation of THz radiation. There are two main categories, namely large-aperture emitters and interdigitated electrodes coupled to antennas. Large-aperture emitters have the advantage of a high active volume, while interdigitated structures provide high electric fields for efficient acceleration of photogenerated carriers. We present a large-aperture emitter consisting of a interdigitated metal-semiconductor-metal (MSM) structure, which combines both advantages. A second metallization layer, which is electrically insulated from the first one, blocks the optical excitation in every second period of the MSM structure, resulting in an unidirectional acceleration of carriers in the device. Focussing fs optical pulses with an average power of 100 mW from a Ti:sapphire oscillator on the emitter lead to THz field amplitudes of up to 85 V/cm (Ubias = 65 V). Excitation with unfocussed radiation from a 1 kHz repetition rate Ti:sapphire amplifier system (average power 10 mW) provided THz field amplitudes of 6 kV/cm (Ubias = 23 V). In case of the excitation with the Ti:sapphire amplifier system a pronounced nonlinear behavior of the THz field amplitude with respect to both the excitation density and the bias electric field was observed.]]></dc:description>

It turns out that the size distribution obtained by SANS complemented with other techniques is well suited to validate models of long-term microstructure evolution, that tensile test and hardness results are well suited to validate models of irradiation-hardening and that the order of magnitude of the yield stress increase and some trends are correctly reproduced by RPV-1 for a low-Cu VVER-1000 RPV steel. The subject should be reconsidered in future after completion of RPV-2 in order to take into account the effect of solutes more adequately.]]></dc:description>

<dc:source><![CDATA[Medical Physics 33(2006)9, 3270-3273]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[In conventional linear accelerators, the flattening filter provides a uniform lateral dose profile. In intensity modulated radiation therapy applications, however, the flatness of the photon field and hence the presence of a flattening filter, is not necessary. Removing the filter may provide some advantages, such as faster treatments and smaller out-of-field doses to the patients. In clinical accelerators the backscattered radiation dose from the collimators must be taken into account when the dose to the target volume in the patient is being determined. In the case of a conventional machine, this backscatter is known to great precision. In a flattening filter free accelerator, however, the amount of backscatter may be different. In this study we determined the backscatter contribution to the monitor chamber signal in a flattening filter free clinical accelerator (Varian Clinac 21EX) with Monte Carlo simulations. We found that with the exception of very small fields in the 18-MV photon mode, the contribution of backscattered radiation to the monitor signal did not differ from that of conventional machines with a flattening filter. Hence, a flattening filter free clinical accelerator would not necessitate a different backscatter correction. (c) 2006 American Association of Physicists in Medicine.]]></dc:description>

<dc:title><![CDATA[The Feasibility of In-Beam PET for Therapeutic Beams of 3He]]></dc:title>
<dc:source><![CDATA[IEEE Transactions on Nuclear Science 53(2006)4, 2252-2259]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[At present in-beam PET is the only possibility for an in-situ monitoring of the particle delivery in hadron tumor therapy and there is a unique clinical implementation at the Gesellschaft fuer Schwerionenforschung (GSI) Darmstadt. Several heavy ion treatment facilities are under construction, which will provide a large variety of ions from protons to oxygen. This requires a precise knowledge of the spatial distribution of beam induced positron emitters in the irradiated volume. For the 3He-case experiments at GSI with three mono-energetic 3He-beams of  130.03 AMeV to 207.92 AMeV and mean intensities varying from 2E8 to 3.6E8 ions/s has been carried out. The beams were stopped in homogeneous thick targets consisting of  PMMA, graphite and water, which were placed in the center of the field of view of the PET-scanner  at the experimental carbon ion therapy at GSI. Results on the production rate and the spatial distribution of 3He ion induced  beta+-activity will be presented and compared with data from 12C-irradiation. From these, the accuracy and resolution for determining the range of the 3He primary beams is deduced. Furthermore, energy dependent thick target cross sections for different reaction channels leading to positron emitters will be estimated from the experimental data.]]></dc:description>

<dc:title><![CDATA[Simulating turbulent mixing in nuclear reactor pressure vessels]]></dc:title>
<dc:source><![CDATA[ANSYS Solutions 7(2006)2, 27-28]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[FZR has 10 years of experience using ANSYS CFX software for CFD applications focused on nuclear reactor applications and more recently also chemical process simulations. These CFD activities are very closely connected to experimental investigations at facilities in the institute. Using advanced two-phase flow measurement techniques, a comprehensive data base for CFD code verification is being created. So in addition to single-phase flow nuclear reactor engineering applications, development and verification of physical models for two-phase flows can be performed. FZR is participating in the German initiative on CFD applications in nuclear reactor safety research in close co-operation with the Gesellschaft für Anlagen- und Reaktorsicherheit (GRS, the German nuclear safety authority) and ANSYS. The group of young and highly motivated CFD scientists that has been established at the  institute also has a significant portion of the 100 processor Linux cluster of the FZR at its disposal. The FZR coordinated the experimental and analytical investigations of turbulent mixing inside pressurized water reactors (PWRs) performed within the EC project FLOMIX-R (Fluid mixing and flow distribution in the reactor circuit). The purpose of this project was to describe coolant mixing phenomena, particularly for severe accident scenarios. Such scenarios include steam line breaks and boron dilution, where mixing of coolant from different loops moderates the inflow of water with insufficient boron content or temperature into the reactor core. These changes can lead to reactor power excursions (rapid increase in reactor power) due to positive reactivity effects. An example of a typical boron dilution scenario is during start-up of the first main coolant pump after a slug of low borated water has formed in one of the cooling loops, where mixing is largely forced by the momentum introduced by the pump starting. Another safety issue arises during emergency core cooling (ECC) situations, when cold water is injected into a hot cooling loop. In this case, buoyancy-driven mixing is influenced by density differences in the fluid and is typical for so-called pressurized thermal shock (PTS) scenarios. When a streak of cold ECC water touches the reactor pressure vessel (RPV) wall, unacceptable thermal stresses can occur. Measurement data from several sets of mixing experiments, using advanced measurement techniques with enhanced temporal and spatial resolution, improved the basic understanding of turbulent mixing and provided data for CFD code verification.
Selected experiments were then simulated using ANSYS CFX and applying best practice guidelines (BPGs), a set of systematic procedures for quantifying and reducing numerical errors. BPGs were applied when considering computational grid resolution and time step, turbulence models, internal geometry modelling, boundary conditions, numerical schemes, and convergence criteria. These investigations highlighted the importance of grid quality, and also the need to minimize numerical diffusion by using second order discretization. In fact, first order schemes were found
to sometimes even provide physically incorrect results. ANSYS CFX was well able to predict the experimental flow patterns and mixing phenomena for both buoyancy-driven and momentum-driven flows. Two-equation turbulence models like k-ω or SST were found to be suitable for momentum-driven slug mixing, while Reynolds stress models provided better results for buoyancy driven mixing.
Comprehensive multiphase flow models, advanced turbulence models, second order discretization, and scalable parallel performance all combine to make ANSYS CFX a valuable tool at FZR. ANSYS CFX software has been instrumental in the development and verification of best practices guidelines for the use of CFD in nuclear safety analyses.]]></dc:description>

<dc:description><![CDATA[Layers of Ti nitride, Ti oxynitrides TiNxOy and Ti oxide were produced by means of metal plasma immersion ion implantation and deposition (MePIIID) from a plasma produced by cathodic arc evaporation of Ti under addition of nitrogen and/or oxygen to the ambient near the substrate. The phase composition and structure of the layers are strongly dependent on the relation of the gases partial pressure. To study the correlation between blood compatibility and physical properties of the coating the thrombocyte adhesion and fibrinogen adsorption on the surface as well as wettability and surface energy were investigated. Thrombocyte adhesion and fibrinogen adsorption are lower for TiNxOy than for TiO2. This correlates with a lower hydrophobicity and higher polar component of the surface energy for TiNxOy.

<dc:description><![CDATA[ABSTRACT
The dual implantation chamber (DIC) at Rossendorf Center for Application of Ion Beams in Materials Research allows materials to be implanted using two ion beams simultaneously. This facility is located at the 45o cross point of two beam lines, one from a single ended HVEE 500 kV ion implanter and the other from a HVEE 3 MV Tandetron accelerator. Each beam line is equipped with independent ion fluence and current control. The special design of the beam sweeping system, enables both ion beams to scan the target surface simultaneously in synchronous mode, i.e. both ion spots are kept at coincident positions over the target. Experiments, concerning the formation of SiC nanoclusters in Si by high dose C and simultaneous Si implantation, are reported.]]></dc:description>

<dc:description><![CDATA[This paper describes the current status of the 3 1/2 cell SRF gun. The SRF photo injector will produce short pulses with high bunch charges and low transverse emittance like the traditional photo injector. The requirement for the ELBE superconducting electron linear accelerator is to provide low emittance electron beam with 1 mA current and 9.5 MeV energy. Additionally, it will easily operate in the CW-mode caused by the low RF power losses in the superconducting material. This is an exceptional property of the mid infrared ELBE-FEL to work in such a regime. Therefore, the normal conducting copper cathode must be cooled by liquid N2 in order to preserve the temperature of the cavity at 2 K. The estimated power input from the RF field into the cathode amounts 10 W. First results of temperature distributions on the cathode respectively the cooling system by a heat load of 10 W are presented.]]></dc:description>

<dc:source><![CDATA[DPG Frühjahrstagung, 13.-15.03.2006, Heidelberg, Deutschland]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[State-of-the-art technology has outperformed the efficiency of the positron emission tomograph installed at the Gesellschaft für Schwerionenforschung for monitoring, in-beam, ion radiation therapy. In addition, the special requirements of in-beam PET have been better understood. We explain these special requisites and present dedicated in-beam PET readout solutions, either tested in-beam or under development. Experimental results obtained with two multi-pixel, gamma-ray detectors consisting of lutetium oxyorthosilicate (LSO) coupled to avalanche photodiode arrays (APDA) show that this detector provides a good solution for improved, next-generation in-beam PET scanners.
Nevertheless, we extrapolate recent detector and scintillator developments, enabling  sub-nanosecond coincidence time resolution (T), onto a possile in-beam time-of-flight (TOF) PET scanner. We show that  T < 200 ps full-width-at-half-maximum allows:
(1) images to be shown to the radiooncologist in real-time,
(2) artifact-free images to be obtained from dual-head tomographs,
(3) an absolute quantification of image intensity and
(4) to obtain optimum PET images corrected from biological washout mechanisms.]]></dc:description>

<dc:description><![CDATA[Plant-measured data provided by the OECD/NEA VVER-1000 coolant transient benchmark programme were used to validate the DYN3D/RELAP5 and DYN3D/ATHLET coupled code systems. Phase 1 of the benchmark (V1000CT-1) refers to an experiment that was conducted during the commissioning of the Kozloduy NPP Unit 6 in Bulgaria. In this experiment, the fourth main coolant pump was switched on whilst the remaining three were running normal operating conditions. The experiment was conducted at 27.5 % of the nominal level of the reactor power. The transient is characterized by a rapid increase in the primary coolant flow through the core, and as a consequence, a decrease of the space-dependent core inlet temperature. The control rods were kept in their original positions during the entire transient. The coupled simulations performed on both DYN3D/RELAP5 and DYN3D/ATHLET were based on the same reactor model, including identical main coolant pump characteristics, boundary conditions, benchmark-specified nuclear data library and nearly identical nodalization schemes. In addition to validation of the coupled code systems against measured data, a code-to-code comparison between simulation results has also been performed to evaluate the respective thermal hydraulic models of the system codes RELAP5 and ATHLET.]]></dc:description>

<dc:description><![CDATA[The so-called "Böttger Stoneware", red porcelain invented by Böttger in the early 18th century, represents an independent development of high technological standard. In comparison to other ceramics Böttger stoneware is characterized by a high material density, consequently greater hardness and suitability for surface polishing. Hence museums show growing interest in obtaining objective criteria based on non-destructive methods of stoneware material analysis. In the present work the possibility of characteristic "fingerprints" for the different provenance of stoneware is tested by making use of ion beam analysis at the external proton beam, i.e. a proton beam on air.]]></dc:description>

<dc:source><![CDATA[Workshop on Multi-Phase Flow: Simulation, Experiment and Application, 31.05.-03.06.2005, Dresden, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The paper contributes to the advanced CFD simulation of subcooled boiling in forced convective flows, with special attention given to the momentum transfer between continuous liquid and vapour bubbles. A wall boiling model, implemented in CFX-5 (Egorov, Menter, 2004) and based on the two-fluid approach, is used here together with the state-of-the-art model correlations for the non-drag forces, available in CFX-5. The paper describes the main concepts of modelling mass, heat and momentum transfer between the phases. Published experimental results for flow in a pipe are used for the model validation.
The model is applied to the simulation of subcooled boiling flow in a hot channel of a fuel rod bundle. Influence of mixing vanes, attached to the spacer grids of fuel assembly in order to enhance the heat transfer, is taken into account. The simulation results demonstrate the capability of the model to estimate the effects of geometrical design on the flow physics.]]></dc:description>

<dc:description><![CDATA[Im Jahr 2004 wurde in Meerane die erste Megawatt-Anlage in Sachsen in Betrieb genommen. Sie liegt in einer vom DWD ermittelten "Sonneninsel" westlich von Chemnitz. Die Anlage befindet sich in einem Gewerbegebiet südlich von Meerane hinter einer Lärmschutzwand an der Autobahn A4. Auf einer Fläche von 2,5 Hektar wurden insgesamt 417 Tische zur Aufnahme der Module errichtet, die Gesamtleistung beträgt 1066 kW. Die Anlage wurde im April 2004 in Betrieb genommen, eine komplette Datenerfassung (einschließlich Einstrahlung und Modultemperatur) erfolgte ab August 2004. In den ersten Monaten traten mehrfach Abschaltungen der Wechselrichter, ausgelöst durch zu geringen Isolationswiderstand des PV-Generators, auf. Ab August 2004 lief die Anlage weitgehend fehlerfrei. 
Der Wechselrichter-Wirkungsgrad lag durchgehend bei 95 %, und das Performance Ratio bei 0,76.
Im Zeitraum August 2004 bis Juli 2005 wurde ein normierter Ertrag von 927 kWh/kW erreicht (siehe Bild 1). Durch aufgetretene technische Störungen trat ein Verlust von etwa 20 kWh/kW auf, so dass bei störungsfreiem Betrieb ein Ertrag von 950 kWh/kW erreicht worden wäre. Da der betrachtete Zeitraum bezüglich der Einstrahlung als "Normaljahr" angesehen werden kann, kann auch künftig im Mittel mit diesem Ertrag gerechnet werden.]]></dc:description>

<dc:description><![CDATA[The lecture gives an introduction into the computational modeling of transients in nuclear reactors. The physical models and numerical methods used in the code DYN3D for the simulation of reactivity initiated accidents in Light Water Reactors are briefly described. The importance of correct numerics for nuclear safety analysis is outlined. Examples are given, how numerical errors and not properly chosen methods can influence the results of transient analyses. Particularly, the importance of low-diffusive numerical schemes for the modelling of transport phenomena like transport of low-borated slugs of coolant is stressed.]]></dc:description>

<dc:source><![CDATA[Nuclear Physics A 757(2005), 329-348]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The conditions for the manifestation of transient effects in fission are carefully examined by analysing experimental data where fission is induced by peripheral heavy-ion collisions at relativistic energies. Experimental total nuclear fission cross sections of U-238 at 1 A GeV on gold and uranium targets are compared with the predictions of a nuclear-reaction code, where transient effects in fission are modeled using different approximations to the numerical time-dependent fission-decay width: a new analytical description based on the solution of the Fokker-Planck equation and two widely used but less realistic descriptions, a step function and an exponential-like function. The experimental data are only reproduced when dissipation is considered. The influence of transient effects on the fission process, as well as the deduced value of the dissipation strength P, depends strongly on the approximation applied for the time-dependent fission-decay width. In particular, a metic!  ulous analysis sheds severe doubts on the use of the exponential-like in-growth function. Finally, we investigate which should be the characteristics of experimental observables to be most sensitive to transient effects in fission. The pertinence of observables related to the excitation energy at saddle is discussed.]]></dc:description>

<dc:description><![CDATA[Microbial diversity was studied in ground waters collected from a monitoring well at the radioactive waste depository Tomsk-7, Siberia, Russia, applying the 16S rDNA retrieval. The results demonstrated dominance of Betaproteobacteria, Bacteroidetes, and a novel Cyanobacteria-like group. The archaeal populations are represented by methanogens and three distinct clusters of Crenarchaeota. The autotrophic bacterial diversity was estimated via the RubisCO approach and the results confirm the dominance of Betaproteobacteria. Oligotrophic bacteria, from the groups of Alphaproteobacteria and Actinobacteria were isolated from the studied site. The strains tolerate relatively high concentration of different heavy metals and interact effectively with uranium. EXAFS analysis demonstrated that they immobilize U(VI) at pH 4.5 extracellularly in a form of meta-autunite. At pH 2 the U was bound by the organic phosphate residues of the cells. The environment around the radioactive waste repository site Tomsk-7 possesses microorganisms with a potential to bind and transport radionuclides.]]></dc:description>

<dc:source><![CDATA[Trends in Cell &amp; Molecular Biology 1(2005), 1-14]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Atherosclerosis is a chronic inflammatory disease with increased stress in response to lipid retention in the vessel wall. Diabetes mellitus type 2 is associated with excessive cardiovascular morbidity and mortality. Since atherogenesis already starts before diabetes is diagnosed, we investigated the oxidative stress in the circulation and its associations with dyslipidemia in impaired glucose tolerance (IGT) and diabetes mellitus type 2. Starting from data of a recent study including 125 IGT subjects, 75 patients with newly diagnosed diabetes mellitus type 2, and 403 subjects with normal glucose tolerance (NGT) the pathological consequences of oxidative and metabolic changes in IGT and diabetes mellitus type 2 will be reviewed. The elevated circulating levels of oxidized low-density lipoprotein (oxLDL) in IGT and diabetes mellitus type 2 subjects were not or only weakly related to the oxidative/antioxidative balance in the blood that was characterized by phagocyte oxidant production, serum paraoxonase activity, total antioxidant capacity, and urate-to-allantoin ratio. The close association between oxLDL levels and plasma LDL cholesterol and triglycerides, respectively, favours the hypothesis that dyslipidemia particularly promotes the oxidation of the modified lipoprotein into circulation.]]></dc:description>

<dc:description><![CDATA[Experiments comparing nitrogen ion implantations in Al5052 by beam and plasma immersion were carried out. Beam implantation (BI) was carried out using a 100 keV, high current beam implanter while the plasma immersion ion implantation (PIII) was obtained using a glow discharge plasma source coupled to a pulsed high voltage supply. A nitrogen BI dose of 5 x 10(17) cm(-2) at 100 keV was attained with near Gaussian implantation profile while the PIII was performed until we reached similar doses with a maximum energy of 15 keV. Implantation profiles were obtained by Auger electron spectroscopy (AES). X-ray diffraction (XRD) indicated the formation of AlN in both cases but it was more clearly demonstrated by high resolution AES. For BI treatment, a buried AlN layer was achieved while for PIII, a layer of AlNxOy close to the surface was seen. Due to the high temperature reached in the PIII processing (400 degrees C), a softening of the Al5052 bulk resulted while for BI processed sa!  mples with < 200 'C an increase in hardness was observed.]]></dc:description>

<dc:description><![CDATA[1.	Introduction 
Integrins are cell surface transmembrane glycoproteins that are found as αβ heterodimers. The αvβ3 integrin is known to be over-expressed in many tumour types and sprouting blood vessels in the tumour, but expressed at lower levels in normal tissues. Peptides containing the Arg-Gly-Asp (RGD) sequence, bind with high affinity to αvβ3 and have found increasing interest for radiolabelling to target v3 receptors and for imaging angiogenesis. Recently, it was demonstrated using [18F]Galacto-RGD and PET that monitoring of αvβ3 is possible in animal models as well as in humans (1). Recent advances in organometallic chemistry enable 99mTc-labelling of biomolecules with high specific activity and high stability. The aim of this study was to use a cyclic RGD derivative, c(RGDyK), containing a Lys residue for derivatisation with different moieties for labelling with 99mTc using novel technetium-cores, such as HYNIC, Tc(CO)3, and Tc(4+1) approaches and to compare chemical and biological properties in vitro and in vivo.
    
2.	Materials &amp; Methods:
c(RGDyK) (RGD) was derivatised with HYNIC (1), Cys (2), 3, 5Me2 pyrazol-1-yl-ethyldiamine RGD (PZ1, 3) and an isonitrile moiety (L3, 4) at the terminal lysine group of c(RGDyK) using standard fmoc chemistry (examples see Fig1). 99mTc-labelling was performed using both Tricine as well as EDDA as coligands for HYNIC-RGD, [99mTc(CO)3(H2O)3]+ was used for labelling Cys-, PZ1 and HYNIC-RGD and Aminotrithiols as coligangds for L3-RGD at high specific activities. Radiolabelled peptides were characterised concerning lipophilicity (octanol/PBS coefficient, RP-HPLC), protein binding using SEC, stability in buffer, serum and tissue homogenates and tested for stability in PBS, Cystein and Histidine solutions, tissue homogenates and serum up to 6 h. Integrin receptor activity was determined in internalisation assays using v3 receptor positive M21 and negative M21-L melanoma cells. Biodistribution and in vivo tumour uptake was evaluated in nude mice carrying M21 and M21-L tumours for selected compounds. 

3.	Results 
All peptides could be labelled at high specific activities and revealed high stability in various solvents. Both lipophilicity as determined by HPLC retention times and log P values (-0.92 to -3.57) and binding to serum proteins (2-32%) varied considerably All 99mTc-labelled peptides showed specific uptake in αvβ3 positive cells with comparable values for all compounds around 1% of total/mg protein except for 99mTc-L1 and L3-RGD with lower values of less than 0.5%. In a mouse tumour model great variations in pharmacokinetic behaviour was found ranging from predominant renal excretion up to predominant hepatobiliar eliminiation. Highest specific values of tumour uptake were found for 99mTc-EDDA/HYNIC-RGD and 99mTc(CO)3-PZ1-RGD (see Fig. 2) with about 2.5% uptake in M21 receptor positive tumours and <1% in receptor negative M21-L tumours with lower intestinal uptake of 99mTc-EDDA/HYNIC-RGD.

4.	Discussion/Conclusion 
Our study provides for the first time data on chemical and biological characterisation of the same peptide labelled with 99mTc using different technetium-cores. It shows the decisive influence of labelling approaches on imaging properties of 99mTc-labelled peptides and the necessity to use different in vitro assays to predict targeting properties in vivo.

<dc:title><![CDATA[Excursions into reversals]]></dc:title>
<dc:source><![CDATA[10th Symposium of SEDI, 09.-14.07.2006, Prague, Czech Republic]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Despite the recent success of fully coupled three-dimensional numerical models of the geodynamo, the very nature of field reversals is still a matter of controversy. A mean-field dynamo model with a spherically symmetric helical turbulence parameter alpha serves us as a sort of minimum dynamo model that exhibits a number of typical reversal features. These  include the asymmetry of reversals, the correlation between field strength and interval length, the existence of an inhibition time, and the bimodal field distribution. We identify the existence of a branch point of the spectrum of the non-selfadjoint dynamo operator as the essential ingredient for reversals to happen (Phys. Rev. Lett. 94 (2005), 184506). We present some evidences for a self-tuning mechanism of highly supercritical dynamos that tend to saturate into a reversal-prone state by driving the branch point and its nearby local maximum of the growth rate towards the zero line (Earth Planet. Sci. Lett. 143 (2006), 828-840). The high supercriticality can  also explain the typical time-scales of asymmetric reversals (arxiv.org/physics/0601011), without taking resort to a turbulent resistivity. The role of the inner core to increase the ratio of excursions to reversals is discussed in the framework of resonant appearance of branch points in dependence on the wavelength of the dynamo source (arxiv.org/math-ph/0602013).]]></dc:description>

<dc:description><![CDATA[The coordination of the U(IV) and U(VI) ions as a function of the chloride concentration in aqueous solution has been studied by U LIII-edge extended X-ray absorption fine structure (EXAFS) spectroscopy. The oxidation state of uranium was changed in situ using a gas-tight spectro-electrochemical cell, specifically designed for the safe use with radioactive solutions. For U(VI) we observed the complexes UO2(H2O)52+, UO2(H2O)4Cl+, UO2(H2O)3Cl20 and UO2(H2O)2Cl3 with [Cl] increasing from 0 to 9 M, and for U(IV) the complexes U(H2O)94+, U(H2O)8Cl3+, U(H2O)6-7Cl22+ and U(H2O)5Cl3+. The distances in the U(VI) coordination sphere are U-Oax = 1.760.02 Å, Oeq = 2.410.02 Å and U-Cl = 2.710.02 Å, the distances in the U(IV) coordination sphere are U-O = 2.410.02 Å and U-Cl = 2.710.02 Å.]]></dc:description>

<dc:description><![CDATA[In order to prepare epitaxially oriented Fe nanoparticles embedded below the surface of an oxide single crystalline host material the method of ion beam synthesis has been explored for MgO(001) and YSZ(001). At a fixed implantation energy and fluence the implantation temperature has been varied between *room temperature* and 1273 K. It was found, that for MgO substrates the fraction of metallic Fe increases up to a maximum of 60% (at 1073 K) as a function of implantation temperature, whilst the Fe depth profile remains the same. The Fe nanoparticles are nonmagnetic at room temperature exhibiting fcc structure. They show a mean diameter of 5 nm and an exclusive orientation relationship to the host. In YSZ the fraction of metallic Fe increases with increasing implantation temperature reaching 100% at 1273 K. However, the nanoparticles formed are of bcc structure with a mean diameter of 13 nm located mainly close to the sample surface. The ferromagnetic behavior is reflected by a magnetic hyperfine field of 330 kOe and a hysteretic magnetization reversal. Electron holography measurements have been carried out in order to visualize the stray field of the particles.]]></dc:description>

<dc:description><![CDATA[Using ion implantation different rare earth luminescent centers (Gd3+, Tb3+, Eu3+, Ce3+, Tm3+, Er3+) were formed in the silicon dioxide layer of a purpose-designed Metal Oxide Silicon (MOS) capacitor with advanced electrical performance, further called a MOS-light emitting device (MOSLED). Efficient electroluminescence was obtained for the wavelength range from UV to infrared with a transparent top electrode made of indium-tin oxide. Top values of the efficiency of 0.3 % corresponding to external quantum efficiencies distinctly above the percent range were reached. The electrical properties of these devices such as current-voltage and charge trapping characteristics, were also evaluated. Finally, application aspects to the field of biosensing will be shown.]]></dc:description>

<dc:description><![CDATA[Using ion implantation different rare earth luminescent centers (Gd3+, Tb3+, Eu3+, Ce3+, Tm3+, Er3+) were formed in the silicon dioxide layer of a purpose-designed Metal Oxide Silicon (MOS) capacitor with advanced electrical performance, further called a MOS-light emitting device (MOSLED). Efficient electroluminescence was obtained for the wavelength range from UV to infrared with a transparent top electrode made of indium-tin oxide. Top values of the efficiency of 0.3 % corresponding to external quantum efficiencies distinctly above the percent range were reached. The electrical properties of these devices such as current-voltage and charge trapping characteristics, were also evaluated. Finally, application aspects to the field of biosensing will be shown.]]></dc:description>

<dc:description><![CDATA[The L10 transition temperatures for chemical ordering in FePd and FePt intermetallic alloys may be substantially reduced by ion irradiation [1]. Alignment of the strong magnetic axis normal to the surface layer was achieved. Recently, we showed via kinetic Monte Carlo simulations [2] that (i) ion-beam-induced reduction of the L10 transition temperature may be understood in terms of vacancy-assisted atomic ordering and that (ii) superstructure alignment results from a small initial directional short range order (DSRO).
In this contribution (i) we present systematic studies of  the ion-irradiation-induced L10 ordering in thin layers, (ii) we predict the evolution of chemical ordering in layers with well-designed initial DSRO, (iii) we study in non-stoichiometric alloys (e.g. Fe1-xPdx) the competition of L10 ordering (FePd) with L12 ordering (Fe3Pd), (iv) we extend our atomistic simulations of ion-irradiation-induced ordering to more complex systems like Heusler alloys and (v) we evaluate the influence of interfaces in nanostructures on the ordering process.

Sehr gute Übereinstimmung wurde bei den Durchsatzkennlinien der vom Hersteller angegebenen Charakteristiken für Luft und Wasser erzielt, es existierte jedoch eine systematische Abweichung bei Luft im Falle hoher Ansprechdrücke durch Realgasverhalten und das Auftreten hohe Ma-Zahlen. Eine CFX-Rechnung mit einem Zweiphasengemisch bei 2 bar Überdruck, 1 mm Blasendurchmesser und 4% Gasanteil ergab eine realistische Erhöhung des Volumenanteils der Gasphase in Abhängigkeit von der Druckabsenkung. Weitere Untersuchungen, insbesondere das Verhalten bei Sattdampf und bei Stoffgemischen im Vergleich mit Experimenten sind geplant.]]></dc:description>

<dc:description><![CDATA[Amorphous carbon films have been applied in biomedical fields as potential biocompatible materials with wettability that can be adjusted by doping with other elements, including F, Si, Ti, O and N. In this study, nitrogen-doped hydrogenated amorphous carbon (a-C:H:N) films were deposited by PIII-D using C2H2 + N-2 gas mixtures. The biocompatibility and anti-thrombotic properties of the films were assessed in vitro. The surface morphology and surface wettability of the films were characterized using atomic force microscopy (AFM) and a contact angle method. The results show no cytotoxicity for all films, and films with appropriate nitrogen doping possess much better endothelial cell growth and anti-thrombotic properties. (c) 2005 Elsevier B.V.

<dc:description><![CDATA[Low temperature doping with transition metals is currently accepted as the silver bullet for the creation of diluted magnetic semiconductors (DMS). Among them, ion implantation offers the possibility for doping at almost any temperature. However, tiny, hardly detectable ferromagnetic nanoparticles created due to phase separation already during implantation can wrongly give the impression of a DMS by means of a pronounced integral magnetization. In this work we would like to present systematic investigations on the formation of ferromagnetic nanoparticles due to 57Fe implantation into ZnO single crystals applying several sensitive analysis techniques. At an implantation temperature of 623 K and implantation energy of 180 keV, a distinct dependence of the nanoparticle formation on the Fe ion fluence was observed.  Below a fluence of 2x1016 cm-2, all Fe is found in nonmagnetic charged states indicating no -Fe-nanoparticle formation as was confirmed using X-ray diffraction. From a fluence of 2x1016 cm-2, superparamagnetic -Fe-nanoparticles are present. They were evidenced by zero-field cooled (ZFC) and field cooled (FC) magnetization curves, x-ray diffraction and transmission electron microscopy. The superparamagnetic blocking temperatures increase with the implanted fluence. An annealing at 823 K for 15 min enhanced the Fe particle formation, but Fe nanoparticles were oxidized after an annealing at 1073 K for 15 min. A further annealing at 1073 K for 3.5 h induced the formed of ZnFe2O4. In a conclusion, we definitely rule out the formation of a diluted magnetic semiconductor in Fe-implanted ZnO at process temperature above 623 K.]]></dc:description>

<dc:source><![CDATA[Chemical Engineering Science 62(2007), 1591-1605]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[The paper presents results of a study on the motion of bubbles rising in upward shear liquid flow in the vicinity of a vertical wall. Bubbles were found to slide along the wall, when their diameter is small. Bubbles could also experience multiple collisions with the wall at certain experimental parameters (geometry of a channel, range of superficial liquid velocity, bubble size, etc). The latter was theoretically predicted by solving the equation of the bubble motion for the lateral direction in the boundary layer of the channel. For this, the available in the literature constitutive models for the interfacial forces acting on a bubble in the vicinity of the wall were used. A simplified 1D model predicting bubble lateral displacement near the wall and taking into account the balance of drag and non-drag forces acting on a bubble was proposed. The numerical results were verified against the experimental ones obtained by non-intrusive high-speed video observations and subsequent image processing.
The experiments on the bubble motion were conducted in a vertical acrylic duct having a square cross-section of 25 cm2 and a height of approximately 1.3 m. Desalinated water and air both taken at the room temperature were used in the experiments. All measurements on the bubble motion were performed at channel heights between 0.8 and 1 m above the gas injection point.]]></dc:description>

<dc:description><![CDATA[The two commonly used approaches to describe the WWER radial reflectors in diffusion codes, by albedos on the core-reflector boundary and by a ring of diffusive assembly size nodes, are discussed. The advantages and disadvantages of the first approach are presented first, then the Koebke's equivalence theory is outlined and its implementation for the WWER radial reflectors is discussed. Results for the WWER-1000 reactor are presented. Then the boundary conditions on the outer reflector boundary are discussed. The possibility to divide the library into fuel assembly and reflector parts and to generate each library by a separate code package is discussed.]]></dc:description>

<dc:description><![CDATA[The presentation describes the setup of a multiphase simulation on the example of the simulation of a bubble column. The results are compared to experiments performed in the FZR applying high speed video and a wire mesh sensor. The comparison shows, that the correct simulation of the non drag forces is essential to reproduce the correct flow pattern. Considering all forces, an excellent agreement toe the measured results can be achieved.]]></dc:description>

<dc:description><![CDATA[Isotopic effects in the fragmentation of excited target residues following collisions of 12C on 112,124Sn at incident energies of 300 and 600 MeV per nucleon were studied with the INDRA 4 detector. The measured yield ratios for light particles and fragments with atomic number Z5 obey the exponential law of isotopic scaling. The deduced scaling parameters decrease strongly with increasing centrality to values smaller than 50% of those obtained for the peripheral event groups. Symmetry-term coefficients, deduced from these data within the statistical description of isotopic scaling, are near =25 MeV for peripheral and <15 MeV for central collisions.]]></dc:description>

<dc:source><![CDATA[Institutskolloquium, 20.02.2006, Bonn, Germany]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Das Interesse an der Entwicklung von Radiopharmaka auf der Basis von Radiometallen wird durch eine Reihe von Faktoren wie zunehmende Verfügbarkeit der Nuklide (Generatoren, Zyklotron), einfache Markierung von Liganden und wachsende Anwendungsmöglichkeiten in klinischen Zentren gestärkt. In Abhängigkeit von den kernphysikalischen Eigenschaften der Radiometallnuklide ergeben sich Einsatzmöglichkeiten in der nuklearmedizinischen Diagnostik und Therapie.
Unsere Untersuchungen konzentrieren sich auf die Radionuklide <SUP>64/67</SUP>Cu und <SUP>188</SUP>Re. Es werden neue Chelatsysteme, die über einen zielsuchenden und einen komplexbildenden Teil für metallische Radionuklide verfügen, vorgestellt. Das betrifft insbesondere sechszähnige Chelate auf der Basis des Bispidins (3,7-Diazabicyclo[3.3.1]nonan) und dendritische Liganden. Als zielsuchende Biomoleküle können prinzipiell Antikörper, spezifische Peptide oder Aptamere eingebaut werden. Möglichkeiten der radioaktiven Markierung von Nukleinsäurebausteinen werden diskutiert.]]></dc:description>

<dc:description><![CDATA[Die faszinierende Erfolgsgeschichte von Leuchtdioden (engl.: light emitting diode, LED) und Laserdioden wird vorgestellt. Es wird erklärt, wie Licht unterschiedlicher Farbe mit LEDs erzeugt wird und welche besondere Rolle blaue LEDs spielen. Neben weißen Leuchtdioden, die ein hohes Potential für zukünftige Alltagsbeleuchtung besitzen, werden auch aktuelle Forschungsergebnisse zu siliziumbasierenden LEDs diskutiert.]]></dc:description>

<dc:source><![CDATA[Multiphase Science and Technology 20(2008), 239-263]]></dc:source>
<dc:date>2008</dc:date>
<dc:description><![CDATA[Water hammer and inertia-driven cavitation hammer phenomena caused by the activation of fast acting valves were studied in a pipeline test facility at Fraunhofer UMSICHT in the context of the EURATOM project WAHALoads. The main goal of the project is the prediction of the loads on equipment and support structures. The presented experiments tackle some scenarios typical for power plants and supply material for the code validation with regard to the modelling of both thermal hydraulic effects and fluid-structure interaction. The test facility Pilot Plant Pipework (PPP) representing an approximately 230 m long experimental pipeline was upgraded in order to allow experiments at system pressures of up to 30 bar at maximum temperatures of about 180 °C. The test rig was furthermore equipped with a test segment that simulates a piping system and the associated supports typical for a (nuclear) power plant. For a better understanding of thermal hydraulic processes during cavitation behind the fast acting valve, novel instrumentation was applied. Wire mesh sensors as well as local void probes were equipped with integrated micro-thermocouples and used for the local instantaneous measurement of both void fractions and fluid temperature. The fast temperature measurement combined with the instantaneous detection of the passage of the gas-liquid interface measurement reveals insights into the condensation heat transfer controlling the speed of the void collapse in case of a condensational water hammer.]]></dc:description>

<dc:source><![CDATA[Environmental Science & Technology 40(2006)15, 4646-4652]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Time-resolved laser-induced fluorescence spectroscopy (TRLFS) and high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) were applied to investigate the species of uranyl(VI) adsorbed onto muscovite platelets and muscovite suspensions ( grain size: 63-200 mu m). TRLFS provided evidence for the presence of two adsorbed uranium( VI) surface species on edge-surfaces of muscovite. The two species showed different positions of the fluorescence emission bands and different fluorescence lifetimes indicating a different coordination environment for the two species. HAADF-STEM revealed that nanoclusters of an amorphous uranium phase were attached to the edge-surfaces of muscovite powder during batch sorption experiments. These U-nanoclusters were not observed on {001} cleavage planes of the muscovite. The surface species with the shorter fluorescence lifetimes are interpreted as truly adsorbed bidentate surface complexes, in which the U(VI) binds to alum!
 inol groups of edge-surfaces. The surface species with the longer fluorescence lifetimes are interpreted to be an amorphous U(VI) condensate or nanosized clusters of polynuclear uranyl(VI) surface species with a particle diameter of 1 to 2 nm. Depending on the size of these clusters the fluorescence lifetimes vary; i.e., the larger the nanosized clusters, the longer is the fluorescence lifetime.]]></dc:description>

<dc:description><![CDATA[Irradiation of reactor pressure vessel (RPV)  steels induces a degradation of the mechanical properties caused by the formation of nano-scale defect-solute clusters. Impurity Cu plays the major role in cluster formation, whereas the effect of the alloying element Ni depends on the Cu level and is not yet well understood.
The present experiment was devoted to the Ni effect. The SANS results for a Fe-3%Ni alloy, pure Fe and model alloys were reported.]]></dc:description>

<dc:description><![CDATA[Hydration of uranyl(VI) ion has been a subject of both theoretical and experimental interests for many years. Most of recent publications from both theory and experimental sides agree that the uranyl(VI) ion in aqueous solution exists as 5-fold UO2(H2O)52+. In this work, we studied the hydration of uranyl(VI, V) and neptunyl(VI) ions in further accurate way by optimizing structures of AnO2(H2O)n2+/+ (n = 4, 5, 6) clusters at the DFT level in aqueous solution using polarizable continuum model (PCM); with special focus on the conformation of coordinating water molecules. A stable energy minimum with no imaginary vibrational frequency was found for UO2(H2O)52+ having U-Oax distance of 1.756 and 1.757Å, and U-Oeq distance of 2.428, 2.436, 2.441, 2.441, and 2.443Å. Three water planes stay perpendicular to the equatorial plane, while two water planes stay parallel to the equatorial plane.

<dc:description><![CDATA[Semiconducting iron disilicide (β-FeSi2) was prepared by ion beam synthesis (IBS) in (111)Si P-type by implantation at 440 ˚C of 195 KeV Fe ions with a dose of 2.1017 Fe+/cm2 followed by annealing in a N2 atmosphere at 900 ˚C for 4 h. Characterization of samples included Rutherford backscattering spectrometry (RBS), X-ray diffraction (XRD) pole figure, and Raman spectroscopy. A mixture of β-FeSi2 and α-FeSi2 was observed in the as-implanted state. A Photoluminescence (PL) measurement at 12K indicates the luminescence peak at the energy of about 0.81 eV corresponding to the band gap energy of β-FeSi2 phase.]]></dc:description>

<dc:description><![CDATA[Many flow regimes in Nuclear Reactor Safety (NRS) Research are characterized by multiphase flows, where one of the phases is a continuous liquid and the other phase consists of gas or vapour of the liquid phase. In the range of low to intermediate volume fraction of the gaseous phase the multiphase flow under consideration is a bubbly or slug flow, where the disperse  phase has to be characterized by an evolving bubble size distribution due to bubble breakup and coalescence processes. The paper presents a generalized inhomogeneous Multiple Size Group (MUSIG) Model, where the disperse gaseous phase is divided into N inhomogeneous velocity groups (phases) and where each of these groups is subdivided into M bubble size classes. Bubble breakup and coalescence processes between all bubble size classes are taken into account by appropriate models. The derived inhomogeneous MUSIG model has been validated against experimental data from the TOPFLOW test facility at the Research Center Rossendorf (FZR). Comparisons of gas volume fraction and velocity profiles with TOPFLOW-074 testcase data are provided, showing the applicability and accuracy of the model for polydispersed bubbly flow in large diameter vertical pipe flow.]]></dc:description>

<dc:source><![CDATA[International Conference "Nuclear Energy for New Europe 2005", 05.-08.09.2005, Bled, Slovenia]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In this work a general-purpose CFD code CFX-5 was used for simulations of subcooled flow boiling. Some important modelling issues were investigated: heat flux partitioning, turbulence modelling and non-drag forces. The subcooled boiling model, available in a custom version of CFX-5, has been  used here. The special treatment of the wall boiling boundary, based on analytical temperature wall function, assures the grid invariant solution.  The calculations been validated against the published experimental data of high-pressure flow boiling in a vertical pipe covering a wide range of conditions (relevant also to the pressurized water reactor).]]></dc:description>

<dc:description><![CDATA[The investigations of insulation debris generation and transport gain in importance regarding the reactor safety research for PWR and BWR considering all types of LOCA as well as short and long term behaviour of emergency core coolant systems.
The background of experimental investigations consists of the generation of a wide data base developing and validating the CFD-models for  the description of particle transport phenomena in flow (e.g. drift, subsidence, sedimentation, resuspension, agglomeration and head loss at hold-up devices) under various geometric and fluidic boundary conditions. Separate effect experiments for the investigation of particle transport phenomena in multidimensional water flow, sedimentation and resuspension processes were carried out at plexi glass test facilities (Column, Ring Channel) using modern flow measurement and digital image processing technologies. The behaviour of gravitating insulation particles in aqueous solution (sink rates or settling velocities) and sedimentation processes were observed at the test facility Column in 2D-geometry. Experiments for the determination of 2D-transport behaviour of different particle sizes in horizontal carrier flow were realised at facility Ring Channel. Experimental results were generated with constant cross section area along the whole channel length as well as with varied cross section areas (e.g. barriers) and strainers.

<dc:source><![CDATA[Radiochimica Acta 95(2007), 103-110]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[The complexation of U(VI) with Aldrich humic acid (HA) was studied at pH 7 under exclusion of CO2. Using two independent laser-induced spectroscopic methods, time-resolved laser-induced fluorescence spectroscopy (TRLFS) and TRLFS with ultrafast pulses (fs-TRLFS), the formation of the ternary U(VI) mono hydroxo humate complex UO2(OH)HA(I) by reaction of UO2OH+ with HA was studied. Assuming that all proton exchanging functional groups of the HA are able to contribute to the complex formation, a mean stability constant of 6.58 ± 0.24 was derived for UO2(OH)HA(I). Alternatively, the analytical data were evaluated based on the metal ion charge neutralization model resulting in a complexation constant of 6.95 ± 0.10 and a loading capacity of 0.76 ± 0.28. An overall complexation constant of log b0.1M = 14.89 ± 0.54 was calculated for the total reaction of U(VI) with HA starting from the non-hydrolyzed UO22+ ion. This value agrees very well with literature data. Taking into account the UO2(OH)HA(I) complex, the speciation of U(VI) in presence of HA was recalculated. It was found, that the formation of UO2(OH)HA(I) can significantly influence the U(VI) distribution in the environmentally relevant pH region. As a consequence, the mobility of U(VI) in natural aquifer systems could be enhanced.]]></dc:description>

<dc:description><![CDATA[The modeling of complex transients in Nuclear Power Plants (NPP) remains a challenging topic for Best Estimate (BE) three-dimensional coupled code computational tools. Nowadays, this technique is extensively used since it allows decreasing conservatism in the calculation models by performing more realistic simulations based on a more precise consideration of multidimensional effects under complex transients in NPPs. This paper represents a contribution to the assessment and validation of coupled code technique through the Kolzoduy VVER-1000 pump trip test. The coupled REALP5/3.3-PARCS/2.6 and DYN3D/3-RELAP5/3.3 code systems are used in simulations. The obtained results are assessed against experimental data and also through the code-to-code comparison.

The DYN3D/RELAP5 computational model of VVER-1000 has been developed and adjusted for simulations with the parallel running scheme (PVM) of RELAP5/PARCS. Also, the macroscopic cross-section library used in the DYN3D/RELAP5 calculations has been adapted to meet the input requirements of PARCS. Prior to the test simulations, the RELAP5/PARCS model of the plant has been assessed in the standalone PARCS and RELAP5 test calculations.

A reasonably good agreement between the experimental data and the calculated results is obtained. For the initial state, the observed discrepancies are mainly due to the absence of ADF correction and the evaluation of the Doppler feedback effect. During the transient, the deviations are mainly due to the combined effect of the measurement uncertainty in the control rod axial position and the estimation of the Doppler effect.]]></dc:description>

<dc:description><![CDATA[The modeling of complex transients in Nuclear Power Plants (NPP) remains a challenging topic for Best Estimate (BE) three-dimensional coupled code computational tools. Nowadays, this technique is extensively used since it allows decreasing conservatism in the calculation models by performing more realistic simulations based on a more precise consideration of multidimensional effects under complex transients in NPPs. This paper represents a contribution to the assessment and validation of coupled code technique through the Kolzoduy VVER-1000 pump trip test. The coupled REALP5/3.3-PARCS/2.6 and DYN3D/3-RELAP5/3.3 code systems are used in simulations. The obtained results are assessed against experimental data and also through the code-to-code comparison.

The DYN3D/RELAP5 computational model of VVER-1000 has been developed and adjusted for simulations with the parallel running scheme (PVM) of RELAP5/PARCS. Also, the macroscopic cross-section library used in the DYN3D/RELAP5 calculations has been adapted to meet the input requirements of PARCS. Prior to the test simulations, the RELAP5/PARCS model of the plant has been assessed in the standalone PARCS and RELAP5 test calculations.

A reasonably good agreement between the experimental data and the calculated results is obtained. For the initial state, the observed discrepancies are mainly due to the absence of ADF correction and the evaluation of the Doppler feedback effect. During the transient, the deviations are mainly due to the combined effect of the measurement uncertainty in the control rod axial position and the estimation of the Doppler effect.]]></dc:description>

<dc:description><![CDATA[Scattering scanning near- field optical microscopy (s-SNOM) is based on the interaction between an optically scattering nano-particle (AFM tip) and a dielectric sample. The size of the scatterer defines the optical resolution of the microscope, which is on the order of a few nanometers. On that scale, the optically anisotropic properties of most samples have to be taken into account [1]. To examine the influence of optical anisotropy on the scattering signal, we excite a ferroelectric sample close to its phonon resonance in the mid infrared regime. As the precisely tunable light source at infrared wavelengths we used a free electron laser (FEL). We have measured the near-field signal at several wavelengths while scanning the sample, as well as the tip-sample distance dependence of the scattered light signal for the 1st, 2nd, and 3rd harmonic signal. The anisotropy is revealed for different sample orientations. Not only are we presenting the first tunable IR near-field measurements on ferroelectric lithium niobate and barium titanate single crystals, but furthermore are our measurements in excellent accordance with recent calculations of optical anisotropy in such systems [1].

<dc:source><![CDATA[Physical Review Letters 95(2005), 086403]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[We report on a field-induced change of the electronic band structure of CeBiPt as evidenced by electrical-transport measurements in pulsed magnetic fields. Above similar to 25 T, the charge-carrier concentration increases nearly 30% with a concomitant disappearance of the Shubnikov-de Haas signal. These features are intimately related to the Ce 4f electrons since for the non-4f compound LaBiPt the Fermi surface remains unaffected. Electronic band-structure calculations point to a 4f-polarization-induced change of the Fermi-surface topology.]]></dc:description>

<dc:description><![CDATA[After the formation of a high point-defect content of vacancies and self- or solute interstitial atoms during neutron-induced displacement cascade processes, the radiation susceptibility of a reactor pressure vessel (RPV) steel is expressed in its capability of defect clustering. These fine-scaled features are the essential microstructural changes and the reason for the enhanced material ageing under irradiation. Small-angle neutron scattering (SANS) provides statistically reliable results about their size distributions and contents in macroscopic volumina. A possible cluster composition can be derived from their magnetic and nuclear scattering intensities.
The content of Cu is the most essential parameter controlling the radiation susceptibility. Ni rich alloys have a higher radiation susceptibility as Ni poor steels with the same content of deleterious elements as Cu. The synergism of Ni and Cu has a catalytical effect on the radiation defect formation. Cu precipitates were not found.]]></dc:description>

<dc:description><![CDATA[A novel <SUP>11</SUP>C-C bond formation based on the palladium-mediated cross-coupling reaction of alkenylzirconocenes with [<SUP>11</SUP>C]methyl iodide is described. The conversion of internal alkynes into the corresponding alkenylzirconocenes followed by transmetalation with Pd(PPh<SUB>3</SUB>)<SUB>4</SUB> and subsequent cross-coupling with [<SUP>11</SUP>C]methyl iodide gave several <SUP>11</SUP>C-labelled alpha,alpha-dimethyl substituted alkenes. The palladium complex Pd(PPh<SUB>3</SUB>)<SUB>4</SUB> proved to be superior to Pt(PPh<SUB>3</SUB>)<SUB>4</SUB> or Ni(PPh<SUB>3</SUB>)<SUB>4</SUB> as transition metal complex. 
The scope and limitations of the novel palladium-mediated cross-coupling reaction of alkenylzirconocenes with [<SUP>11</SUP>C]methyl iodide were tested with various internal alkynes. Radiochemical yields of up to 75% (based upon [<SUP>11</SUP>C]methyl iodide) could be achieved]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[In this work, nitrogen plasma immersion ion implantation (PIII) treatment of austenitic stainless steels 1.4301 and 1.4571 was performed to investigate the influence of the process conditions on the corrosion properties. Short treatment, high voltage and high temperature result in a decreased corrosion potential while no correlation to layer thickness, nitrogen concentration or lattice expansion was found. Except for the possibility of small CrN agglomerates at high temperatures, no direct explanation for the results can be provided and it is argued that intrinsic stress accumulation and relaxation may be responsible.]]></dc:description>

<dc:description><![CDATA[Plasma immersion ion implantation (PIII) has been employed for nitrocarburizing 304 stainless steel. The sample was treated at relatively low gas pressure of nitrogen and acetylene in the range of 10(-3) mbar. The microstructure variation, the austenite lattices spacing and the phase transformations were studied in-situ during heating up to 800 degrees C and after cooling, using synchrotron X-ray diffraction. Glow discharge optical spectroscopy (GDOS), optical microscopy and hardness profile measurements have been used before and after thermal treatment to analyse the nitrocarburized layer.

<dc:title><![CDATA[Speciation of Uranyl Nitrato Complexes in Acetonitrile and in the Ionic Liquid 1-Butyl-3-methylimidazolium Bis(trifluoromethylsulfonyl)imide]]></dc:title>
<dc:source><![CDATA[European Journal of Inorganic Chemistry 32(2007), 5120-5126]]></dc:source>

<dc:description><![CDATA[Complex formation between the uranyl ion and nitrate ions in acetonitrile and the ionic liquid 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([C4mim][Tf2N]) has been studied by absorption, magnetic circular dichroism (MCD) and uranium LIII EXAFS spectroscopy. The experimental results point to the existence of a trinitrate species [UO2(NO3)3] with D3h symmetry in both solvents. The atomic distances in the uranium(VI) coordination sphere for the trinitrato complex in acetonitrile are UOax = 1.770.01 Å and UOeq = 2.480.01 Å. EXAFS data show that the uranyl ion in the ionic liquid is surrounded by six oxygen atoms in the equatorial plane at a distance of 2.490.01 Å. The UN distance of 2.920.01 Å indicates a bidentate coordination of the nitrate group in both solvents. A structural comparison is made between the uranyl trinitrato complex anion [UO2(NO3)3] and the uranyl tricarbonato complex anion [UO2(CO3)3]4. No evidence is found for the presence of uranyl nitrato complexes in aqueous solution. The optical absorption, MCD and EXAFS spectra resemble those of the hydrated free uranyl ion. There are two axial oxygen atoms at 1.770.01 Å and five equatorial oxygen atoms at 2.410.01 Å. These values agree well with structural parameters obtained for the uranyl aqua ion.]]></dc:description>

<dc:source><![CDATA[Multiphase Science and Technology 20(2008), 239-263]]></dc:source>
<dc:date>2008</dc:date>
<dc:description><![CDATA[Some of the accident scenarios discussed for VVER-440 reactors assume an overfeed of the secondary side of the steam generators by water coming either from the primary side or from the feed water system. This may happen, for example, in case of a leakage from the primary to the secondary side as well as during earthquakes and may lead to a water ingress into the main steam-lines, where condensation induced water hammer may be the consequence. The present work was initiated to study this phenomenon experimentally. For this purpose the PMK-2 test facility of KFKI-AEKI Budapest, an integral thermo- hydraulic model of a VVER-440 / W213, was extended by a steam-line model, which is equipped with a novel two-phase flow instru-mentation as well as fast pressure and strain-gauge transducers. The applied mesh sensor de-veloped by Forschungszentrum Rossendorf allows a visualisation of the transient flow section during the water hammers. Local void probes detect the propagation of slugs along the pipe. The applied new kind of probe is equipped with micro-thermocouples to provide local instan-taneous temperature measurements beside the phase detection. This allows to assess tempera-ture gradients at the boundary between water and steam. The paper describes test facility and new instrumentation. The results of the first tests are presented and discussed. The work is part of the WAHALoads project, which was performed within the 5th EU framework programme.]]></dc:description>

<dc:source><![CDATA[Philosophical Magazine 87(2007)12, 1855-1870]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[We present the first small angle neutron scattering (SANS) study of neutron irradiated, annealed and reirradiated VVER440-type reactor pressure vessel weld material. The SANS results are analyzed in terms of the size distribution of irradiation-induced defect/solute atom clusters and of the ratio of total and nuclear scattering intensity in a saturation magnetic field (A-ratio). The measured A-ratio is compared with calculations performed for the cluster composition reported by Pareige et al. [Phil. Mag. 85 (2005) 429-441] for a similar weld material investigated by means of three-dimensional atom probe tomography. The observed deviation between both estimates and possible reasons for the discrepancy are discussed. Special emphasis is placed on the differences between the materials response to the original irradiation and to reirradiation after annealing. We have observed that reirradiation-induced clusters are different in composition and their formation saturates at a lower volume fraction than in the case of the original irradiation.]]></dc:description>

<dc:source><![CDATA[Geobiology 3(2005)4, 275-285]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Changes of natural bacterial community structure induced by addition of uranyl or sodium nitrate to weakly contaminated soil samples from a uranium mining waste pile were studied using the 16S rDNA retrieval. Our results demonstrated that both treatments caused drastic changes in bacterial composition of the studied samples resulting in strongly reducing the originally predominant Acidobacteria and Alphaproteobacteria. The addition of sodium nitrate induced a strong propagation of denitrifying and nitrate reducing populations of Actinobacteria and of Bacteroidetes. The treatment of the samples with uranyl nitrate demonstrated that most part of the mentioned Bacteroidetes and some of the actinobacterial populations do not tolerate high U(VI) concentrations. Most interesting is the strong propagation of Gamma-Pseudomonas spp. capable to accumulate significant amounts of U(VI) and to build biofilms, hence being able to protect the community from the added toxic metal. At the initial stages of incubation (four weeks after the addition of uranyl nitrate) also U(VI) reducing Geobacter spp. appeared. However, at the later stages of incubation (fourteen weeks after the supplementation) no Geobacter populations were detected anymore. The latter indicated that no biological reduction of U(VI) occurred in these samples most probably because of the lack of electron donors to support this reaction. Interestingly, different U-sensitive Bacteroidetes and alphaproteobacterial populations propagated in the U(VI) treated samples at these late stages of incubation. That indicated that the added U(VI) was immobilized and did not disturb anymore the studied bacterial community. 
The drastic changes induced by the addition of U(VI) indicate that bacterial communities are able to protect their members from the toxicity of this radionuclide by propagation of resistant and capable to interact with U(VI) populations. On the other hand, the large number of dead bacteria liberates phosphate-rich and other biopolymers capable to bind U(VI). Hence, bacteria together with the abiotic soil components such as minerals and humic acids play a key role in the immobilization  of  U(VI) in nature.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[Biological ceramic composites (biocers) were used as a template to produce Pd(0)-nanoparticles. The metal binding cells of the uranium mining waste pile isolate Bacillus sphaericus JG-A12 were used as biological component of the biocers and immobilized by using sol-gel technology. Vegetative cells and surface layer proteins of this strain are known to bind high amounts of Pd(II) that can be reduced to Pd(0) particles by the addition of a reducing agent. After embedding into sol-gel ceramics, the cells retained their Pd(II)-binding capability. Pd(0)-nanoclusters were produced by the addition of hydrogen as reducing agent after the sorption of Pd(II). The formed Pd(0) nanoparticles were investigated by EXAFS-spectroscopy. The particles had a size of 0.6-0.8 nm. The thus immobilized Pd nanoparticles possess very interesting physical and chemical properties and are of interest for technical applications.]]></dc:description>

<dc:description><![CDATA[The complex formation of curium(III) with L2-Aminobutyric acid, L-Threonine and O-Phospho-L-Threonine was determined by time-resolved laser-induced fluorescence spectroscopy (TRLFS) at trace Cm(III) concentrations (3x10-7 M). The concentrations of L2-Aminobutyric acid and L-Threonine were varied between 0.001 and 0.25 M in the pH range of 2 to 9.6 using 0.5 M NaCl as background electrolyte. In the case of O-Phospho-L-Threonine, lower concentrations were applied varying from 1x10-4 to 0.025 M in the pH range 2.8 to 7.6 using 0.154 M NaCl as background electrolyte.
	Curium species of the type MpHqLr were identified from the fluorescence emission spectra. Three CmL2-Aminobutyrate complexes could be determined: (i) CmL2+ with a peak maximum at 596.0 nm, (ii) CmL2+ with a peak maximum at 600.8 nm, and (iii) CmL3 with a peak maximum at 603.8 nm. The corresponding formation constants were calculated from TRLFS measurements to be log β101 = 5.17 ± 0.07, log β102 = 9.00 ± 0.07, and log β103 = 11.30 ± 0.09. In the CmThreonine system, also three different species could be characterized: (i) CmThr2+ with a peak maximum at 599.6 nm, (ii) CmThr2+ with a peak maximum at 603.2 nm, and (iii) CmThr2- with a peak maximum at 605.7 nm. These species show the following formation constants: log β101 = 6.72 ± 0.07, log β102 = 10.22 ± 0.09, and log β1-22 = -(7.22 ± 0.19). Two species could be identified in the CmPhosphothreonine system: (i) CmH2PThr2+ with a peak maximum at 597.0 nm and (ii) CmHPThr+ with a peak maximum at 601.0 nm. The formation constants of the Cm-Phosphothreonine complexes were calculated to be log β121 = 18.03 ± 0.13 and log β111 = 14.17 ± 0.09. Possible structures of the identified curium species will be discussed on the basis of the fluorescence lifetime measurements. 
For a better understanding of the actinide interaction processes in biological systems such as microbes and plants on a molecular level, it is essential to explore their complexation with selected bioligands of relevant functionalities as model compounds.

<dc:description><![CDATA[Introduction: Alterations of a7 nAChR have been observed in schizophrenia, brain trauma and neurodegenerative diseases. For PET imaging of a7 nAChR [18F]NS10743 has been successfully developed evaluated in mice by tissue distribution and specificity studies. Here we report on baseline and blocking PET studies with [18F]NS10743 in pig brain. 
Methods: [18F]NS10743 was synthesized with high specific activity (>150 GBq/μmol) and radiochemical purity (>99%). Dynamic PET scanning was performed in anaesthetized female piglets (13-15 kg), intravenously injected with ~ 330 MBq [18F]NS10743 (total mass ~ 472 ng) for 120 min. Three animals additionally received 3 mg/kg of the a7 nAChR partial antagonist NS6740 at 10 min pre-tracer injection followed by a continuous infusion (1 mg/kg/h). Plasma samples were taken and metabolite-corrected input functions were estimated. Individual regions of interest were defined using an MRI-based template of pig brain. SUV and distribution volume (VT = K1/k2) were estimated. The ratio of specifically bound radioligand and non-displaceable radioligand in brain tissue was calculated from the VT values by BPND = (VT region - VT reference)/VT reference.
Results: [18F]NS10743 readily passed the blood-brain barrier and the uptake of radioactivity peaked with SUV = 2.23 ± 0.71 at 8 min in the baseline scan while in NS6740-blocking studies the radioactivity levels peaked significantly earlier (SUV = 3.02 ± 1.28 at 5 min) and decreased faster. At the end of study (between 90 and 120 min p.i.) SUV was significantly decreased by NS6740 in allinvestigated brain regions except olfactory bulb, which was chosen as reference region for calculation of BPND. At baseline, a VT value of 6.07 ± 1.54 was estimated for the whole brain with the highest radiotracer accumulation in the temporal, parietal, and occipital lobe, thalamus, striatum, and middle cortex (VT = 7.27 ± 1.95  7.10 ± 1.58). Intermediate binding was observed in hippocampus, colliculi, midbrain, frontal lobe, and ventral cortex (VT = 6.76 ± 1.71  6.09 ± 1.05), and lowest values were assessed in the cerebellum, pons, and olfactory bulb (VT = 5.71 ± 1.18  4.11 ± 0.96). Baseline BPND values for high (temporal lobe), median (hippocampus) and low specific binding (cerebellum) were 0.76 ± 0.07, 0.54 ± 0.08, and 0.39 ± 0.08, respectively. NS6740 significantly reduced the binding potential BPND in regions with high [18F]NS10743 binding (temporal lobe: -29 %, p = 0.01; midbrain: -35 %, p = 0.02) while the decrease in regions with low binding was not significant (cerebellum: -16 %, p = 0.2).
Conclusion: These data make [18F]NS10743 a reasonable candidate for further development of in vivo a7 nAChR imaging by PET. The challenge to improve the binding potential of [18F]NS10743, limited mainly by the low density of a7 nAChR expression in the brain and reflected by rather small regional differences in baseline uptake of [18F]NS10743, will be met by further modifications of the NS10743 core structure intended to increase the target affinity of the tracer compound.

<dc:date>2006</dc:date>
<dc:description><![CDATA[In-beam positron emission tomography (in-beam PET) is currently the only method for an in-situ monitoring of highly tumour-conformed charged hadron therapy. At the experimental carbon ion tumour therapy facility, running at the Gesellschaft fuer Schwerionenforschung, Darmstadt, Germany, all treatments have been monitored by means of a specially adapted dual-head PET scanner.
The positive clinical impact of this project triggered the construction of a hospital-based hadron therapy facility, with in-beam PET expected to monitor more delicate radiotherapeutic situations.
Therefore, we have studied possible in-beam PET improvements by optimising the arrangement of the gamma-ray detectors.
For this, a fully 3D, rebinning-free, maximum likelihood expectation maximization algorithm applicable to several closed ring or dual-head tomographs has been developed. The analysis of beta+ activity distributions simulated from real-treatment situations and detected with several detector arrangements allows to conclude that a dual-head tomograph with narrow gaps yields in-beam PET images with sufficient quality for monitoring head and neck treatments.
For monitoring larger irradiation fields, e.g. treatments in the pelvis region, a closed-ring tomograph was seen to be highly desirable. Finally, a study of the space availability for patient and bed, tomograph and beam 
portal proves the implementation of a closed-ring detector arrangement for in-beam PET to be feasible.]]></dc:description>

<dc:source><![CDATA[European Physical Journal A 27(2006), 129-136]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The  decays of 102 Sn and 104 Sn were studied by using high-resolution germanium detectors as well as a Total Absorption Spectrometer (TAS). For 104 Sn, with three new  beta-delayed gamma rays identified, the total Gamow-Teller strength (BGT) value of 2.7(3) was obtained. For 102Sn, the gamma-gamma coincidence data were collected for the first time, allowing us to considerably extend the decay scheme. This scheme was
used to unfold the TAS data and to deduce a BGT value of 4.2(8) for this decay. This result is compared to
shell model predictions, yielding a hindrance factor of 3.6(7) in agreement with those obtained previously for 98Cd and 100In. Together with the latter two, 102 Sn completes the triplet of Z < 50, N > 50 nuclei
with two proton holes, one proton hole and one neutron particle, and two neutron particles with respect to the doubly magic 100Sn core.]]></dc:description>

<dc:description><![CDATA[The three-dimensional velocity field of a propeller driven liquid metal flow in a cylindrical vessel is reconstructed by a contactless inductive flow tomography (CIFT). A reliable online monitoring of the flow can already be achieved by applying the external magnetic field alternately in two orthogonal directions and by measuring the corresponding sets of induced magnetic fields. The results of the new  technique are shown to be in satisfactory agreement with ultrasonic measurements.]]></dc:description>

The results are comparable with literature data obtained by the density-functional theory. Then, the lifetime of the antisite pair configurations is calculated for temperatures between 800 and 2500 K. Both in 3C- and 4H-SiC the thermal stability of the antisite pairs is rather low. In contrast to previous theoretical interpretations, the antisite pair cannot be therefore correlated with the DI photoluminescence center that is stable to above 2000 K. The atomic mechanism of the recombination of the antisite pair in 3C-SiC and of three antisite pair configurations in 4H-SiC is a modified concerted exchange. Due to the different sizes of the silicon and the carbon atoms, this process is not identical to the concerted exchange in Si. Two intermediate metastable configurations found during the recombination are similar to the bond defect in Si. Since the SiC lattice contains two types of atoms, there are also two different types of bond defects. The two bond defects can be considered as the result of he incomplete recombination of a carbon vacancy and a neighboring mixed dumbbell interstitial. The antisite pair in 4H-SiC with the two atoms on hexagonal sites has a slightly higher formation energy than the other three antisite pair configurations in 4H-SiC. Its lifetime shows another dependence on the temperature, and its recombination is characterized by a separate motion of atoms. The comparison with results obtained by molecular dynamics simulations that are based on the density-functional theory demonstrates that the atomistic simulations describe the antisite pair and its recombination reasonably well.]]></dc:description>

<dc:source><![CDATA[Surface &amp; Coatings Technology 196(2005), 312-316]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The hard Ti-based coating TiAlN has been produced by plasma immersion ion implantation-assisted deposition (PIIIAD) on austenitic stainless steel. In PIIIAD, the substrate is exposed to cathodic arc plasma comprising of metallic ions corresponding to the cathode composition, and the substrate is biased pulsed negative. The pulsed bias of the substrate renders alternate phases of deposition (during the bias off time) and implantation and deposition (during bias on time), thereby controlling deposition temperature, reduction of compressive stresses, increase of crystallinity and enhancing adhesion of coating to substrate. The deposition has been carried out in a neutral as well as reactive nitrogen environment, which leads to nitrogen-containing coatings. In addition to TiAlN, also, Ti, TiN and TiAl were produced to investigate the effect of the different elements. All the coatings are tested for their suitability as biocompatible coatings, and hence, the adherence of osteoblast progenitor cells to these coatings was investigated in correlation with deposition parameters and surface morphology. The results identify the coatings that are wear resistant and suitable for orthopaedic implants.]]></dc:description>

<dc:description><![CDATA[The dynamo action is generally believed to be the origin of cosmic magnetic field generation. Usually, the numerical treatment of dynamo actions is carried out in the framework of the differential equation approach. In the present work, an integral equation approach is developed to simulate the dynamo actions with arbitrary geometries in general and the von Karman sodium experiment in particular. It is found that the lid layers in VKS experiment facility have an ambivalent effect on the efficiency of the dynamo. The induced magnetic field obtained recently by the integral equation approach shows a good agreement with the experimental result. The integral equation approach demonstrates a number of practical advantages: robust, numerically stable, fast and accurate. These features make it a good forward solver for inverse problems of dynamo experiment and other technical applications of magnetohydrodynamics. A test example to infer the velocity field of Riga dynamo experiment is presented.]]></dc:description>

<dc:source><![CDATA[Dresdner Transferbrief 2(2005), 13-13]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Die fortschreitende Miniaturisierung mikroelektronischer Strukturen sowie deren Kombination mit optischen, mechanischen oder magnetischen Komponenten erfordern laufend neue physikalische und technologische Ansätze. Im Forschungszentrum Rossendorf wird im Rahmen von zwei Projekten, getragen von der Deutschen Forschungsgemeinschaft (DFG), intensiv an der Entwicklung und Untersuchung von Nanostrukturen für die Elektronik der Zukunft gearbeitet. So beschäftigt sich das FZR-Institut für Ionenstrahlphysik und Materialforschung u. a. mit der reproduzierbaren Herstellung von maßgeschneiderten Nano-Drähten, die möglichst passfähig zur herkömmlichen Silizium-Techologie sein sollen. 

Die Herstellung dieser Drähte beruht auf der Ionenstrahlsynthese, schematisch in Abb. 2 dargestellt. Hierzu werden feine Linien von Cobalt-Ionen mit dem Fokussierten Ionenstrahl (FIB; Focussed Ion Beam) in ein Silizium-Substrat bei erhöhten Temperaturen implantiert und in einem folgenden Ausheilprozess zu einem Cobaltdisilizid-Draht (CoSi2) synthetisiert. Dabei wird die Kombination zweier wesentlicher Aspekte ausgenutzt. Zum einen wird der geringe  Drahtdurchmesser durch die hohe Fokussierbarkeit  des FIB auf kleiner als 50 Nanometer erreicht, auch als top-down-Ansatz bezeichnet. Zum anderen führen selbst-organisierende Prozesse, der bottom-up-Ansatz, zu einer weiteren Konzentration der implantierten Cobalt-Verteilung. Dies ermöglicht die Synthese von Nanostrukturen mit einem Durchmesser von 10 bis 20 Nanometer. 

Der Schwerpunkt der Arbeiten konzentriert sich zunächst auf das zur Mikroelektronik-Technologie kompatible Cobaltdisilizid. Dieses Material ist metallisch, weist eine sehr gute Leitfähigkeit auf und ist hinsichtlich der Gitterstruktur der des Siliziums sehr ähnlich. Die ersten Ergebnisse sind vielversprechend, nun gilt es, die Reproduzierbarkeit sowie die genaue Platzierung der Drähte im Material zu gewährleisten. Auf dem Weg hin zu neuen Nano-Bauelementen für die Mikroelektronik ist also noch viel zu tun.]]></dc:description>

Up to present, no dynamo effect was measured in this facility, despite the fact that the sodium flow has been carefully optimized. We show that lid layers, i.e. layers of liquid sodium between the impellers and the end walls of the cylinder, and  the flow therein are responsible for a dramatic increase of the critical magnetic Reynolds number for cylindrical dynamos of this kind. Possible solutions of this problem are discussed for the real dynamo facility.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[This paper presents a method for choosing the optimal regularization parameter in EXAFS analysis based on the L-curve-criterion without any external pa-rameter. The L-curve is a log-log plot of the norm of regularized solution ver-sus the norm of the corresponding residual norm. The optimal regularization parameter is chosen as a maximum of the L curve curvature. We apply this method in two experimental cases: crystalline Cu with well-known structure and aqua-ion Cm+3 with unknown structure. The optimal regularization pa-rameter leads to a stable solution with a good convergence of the iterative process]]></dc:description>

<dc:source><![CDATA[36th Journées des Actinides, 01.-04.04.2006, Oxford, Great Britain]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[There is a mechanism of secondary mineral colloid generation straight at the water-rock interfaces by the weathering of the rock material. It is of importance in the unsaturated zone as for instance in mine waste rock piles. Here we demonstrate the influence of iron-rich colloids generated by this mechanism on the behaviour of uranium(VI). The weathering of phyllite from an abandoned uranium mine in waters poor in cations and anions (rainwater) was simulated. The colloids produced by the weathering of this phyllite were able to keep large fractions (up to 90 %) of the uranium(VI) in a colloid-borne form in the pH region of 5.0 to 7.5. In the absence of colloids, this U(VI)) would have been truly dissolved in this pH region. The consequences of this colloid influence on uranyl speciation in natural oxic waters depend on the specific conditions in a geological environment. In a mine waste rock pile both, situations where the iron-rich colloids increase U(VI) mobility by preventing UO22+ attachment at interfaces and situations where the colloids immobilize U(VI) by scavenging, colloid aggregation, colloid deposition, formation of crusts etc., are possible]]></dc:description>

<dc:description><![CDATA[Natural aquatic and terrestrial environments comprise large variations in redox states. Actinides with their variable oxidation states are especially susceptible to these redox conditions. They form aqueous complexes which may greatly differ by solubility and mobility. These complexes are often difficult to investigate due to their thermodynamic metastability. 

Therefore, we developed a spectro-electrochemical cell to study the speciation and structure of aqueous actinide complexes in situ by X-ray absorption spectroscopy, while applying and maintaining a constant potential. Due to the specific safety requirements for handling radioactive materials the electrochemical cell is equipped with two safety compartments and a special electrode arrangement.]]></dc:description>

<dc:title><![CDATA[Atomistic study of the mobility of small interstitial clusters in silicon]]></dc:title>
<dc:source><![CDATA[11th Int. Autumn Meeting on Gettering and Defect Engineering in Semiconductor Technology (GADEST), 25.-30.09.2005, Giens, France]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In this work a comprehensive atomistic study is performed in order to get a better understanding  of the mechanisms of di- and tri-interstitial diffusion at different temperatures and to obtain more data for their diffusivities and migration barriers. A classical potential approach is employed since it allows the investigation of defect migration under relatively realistic conditions, by considering a large computational cell, a very long simulation time, and different initial conditions. In order to test the potential employed, at first the structure and energetics  of di- and tri-interstitials are determined and the results are compared with the data obtained by tight-binding and density-functional-theory calculations. 
The migration of mono-, di- and tri-interstitials is investigated for temperatures between 800 and 1600 K. The defect diffusivity, the self-diffusion coefficient per defect and the corresponding effective migration barriers are calculated. Compared to the mono-interstitial, the di-interstitial migrates faster, whereas the tri-interstitial diffuses slower. The mobility of the di- and the mono-interstitial is higher than the mobility of the lattice atoms during the diffusion of these defects. On the other hand, the tri-interstitial mobility is lower than the corresponding atomic mobility. The migration mechanism of the di-interstitial shows a pronounced dependence on the temperature. At low temperature a high mobility on zigzag-like lines along a <110> axis within a {110} plane is found, whereas the change between equivalent <110> directions or equivalent {110} planes occurs seldom and requires a long time. At high temperature a frequent change between equivalent <110> directions or {110} planes is observed. During the diffusion within {110} planes the di-interstitial moves like a wave packet so that the atomic mobility is lower than that of the defect. On the other hand, the change between equivalent {110} migration planes is characterized by frequent atomic rearrangements. The visual analysis of the tri-interstitial diffusion reveals complex migration mechanisms and a high atomic mobility.  The implications of the present results for the explanation of experimental data on defect evolution and migration are discussed.

<dc:description><![CDATA[The uranyl tricarbonato complex is one of the most important uranyl species under environmental conditions. The tendency to form stable metal-uranyl tricarbonato complexes was found particularly for the interaction with alkaline earth elements. However, under comparable chemical conditions the formation of these complexes is very different. While magnesium tends mainly to the formation of a MgUO2(CO3)32+ - complex, in the case of calcium the Ca2UO2(CO3)3(aq.) complex is the most stable  and the formation of the CaUO2(CO3)32+ - complex is very limited. In the corresponding systems with strontium as well as for barium only the MeUO2(CO3)32+ - complex is formed. The stability constants of the MeUO2(CO3)32+ - complexes increase in the series Mg, Ca , Sr and Ba. The formation of Me2UO2(CO3)3  complexes for Mg, Sr and Ba occurs only in a small concentration range and the formed complexes tends to precipitate. The Me2UO2(CO3)3  complexes for Mg and Ca form stable minerals as bayleyite and liebigite. However several other mineral modifications as zellerite, fontanite, sharpite and rabbittite underline the geochemical importance of this class of compounds.
Analogous phenomena can be expected in the alkaline earth uranyl phosphate systems and results for the formation of species of the type Mex(UO2PO4)y will be presented.]]></dc:description>

<dc:source><![CDATA[First Plenary Meeting RPV & Internals - Physics Modelling, 19.-21.01.2005, Manchester, Great Britain]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The aim of the present talk is to contribute small-angle neutron scattering (SANS) data to the experimental database. Some preliminary conclusions can be drawn from the comparison of SANS data for the materials selected within the workpackage WPII-3. SANS allows for the determination of the size distribution of irradiation-induced clusters and, in particular, for the calculation of mean radius and volume fraction. The mean radius was found to be constant (about 1 nm) and independent of the material under the present experimental conditions. The volume fraction turned out to depend on irradiation conditions and chemical composition of the material. Additional partial information on the composition of clusters is implied in the A-ratio.]]></dc:description>

<dc:source><![CDATA[Nuclear Technology 152(2005)1, 3-22]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Air-water two-phase flow tests in a large vertical pipe of 194.1 mm inner diameter are reported. Close to the outlet of a 9 m tall test section two wire-mesh sensors are installed that deliver instantaneous void fraction distributions over the entire cross section with a resolution of 3 mm and 2500 Hz used for fast flow visualization. Void-fraction profiles, gas velocity profiles and bubble size distributions were obtained. A comparison to a small pipe of 52.3 mm inner diameter (DN50) revealed significant scaling effects. Here, the increase of the air flow rate leads to a transition from bubbly via slug to churn turbulent flow. This is accompanied by an appearance of a second peak in the bubble size distribution. A similar behavior was found in the large pipe, though the large bubbles have a significantly larger diameter at identical superficial velocities, the peak is less high but wider. These bubbles move more freely in the large pipe and show more deformations. Shapes of such large bubbles were characterized in three dimensions. They can rather be complicated and far from ideal Taylor bubbles. Also the small bubble fraction tends to bigger sizes in the large pipe.]]></dc:description>

In Abhängigkeit von den kernphysikalischen Eigenschaften der Radiometallnuklide ergeben sich Einsatzmöglichkeiten in der nuklearmedizinischen Diagnostik und Therapie.
Für Kupfer stehen eine Reihe von Radionukliden zur Verfügung, die einen diagnostischen und therapeutischen Einsatz erlauben. Es werden verschiedene Anwendungsmöglichkeiten diskutiert und eigene Arbeiten zur Entwicklung neuer Chelatsysteme vorgestellt. Das betrifft sechszähnige Chelate auf der Basis des Bispidins (3,7-Diazabicyclo[3.3.1]nonan) sowie dendritische Liganden.]]></dc:description>

<dc:source><![CDATA[Amino Acids 29(2005)4, 389-404]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[The human organism is exposed to numerous processes that generate reactive oxygen species (ROS). ROS may directly or indirectly cause oxidative modification and damage of proteins. Protein oxidation is regarded as a crucial event in the pathogenesis of various diseases ranging from rheumatoid arthritis to Alzheimer's disease and atherosclerosis. As a representative example, oxidation of low density lipoprotein (LDL) is regarded as a crucial event in atherogenesis. Data concerning the role of circulating oxidized LDL (oxLDL) in the development and outcome of diseases are scarce. One reason for this is the shortage of methods for direct assessment of the metabolic fate of circulating oxLDL in vivo. We present an improved methodology based on the radiolabelling of apoB-100 of native LDL (nLDL) and oxLDL, respectively, with the positron emitter fluorine-18 (<SUP>18</SUP>F) by conjugation with N-succinimidyl-4-[<SUP>18</SUP>F]fluorobenzoate ([<SUP>18</SUP>F]SFB). Radiolabelling of both nLDL and oxLDL using [<SUP>18</SUP>F]SFB causes neither additional oxidative structural modifications of LDL lipids and proteins nor alteration of their biological activity and functionality, respectively, in vitro. The method was further evaluated with respect to the radiopharmacological properties of both [<SUP>18</SUP>F]fluorobenzoylated nLDL and oxLDL by biodistribution studies in male Wistar rats. The metabolic fate of [<SUP>18</SUP>F]fluorobenzoylated nLDL and oxLDL in rats in vivo was further delineated by dynamic positron emission tomography (PET) using a dedicated small animal tomograph (spatial resolution of 2 mm). From this study we conclude that the use of [<SUP>18</SUP>F]FB-labelled LDL particles is an attractive alternative to, e.g., LDL iodination methods, and is of value to characterize and to discriminate the kinetics and the metabolic fate of nLDL and oxLDL in small animals in vivo.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[The SANS experiment is aimed at studying the influence of neutron fluence and Ni content on irradiation-induced changes of the microstructure of WWER 1000-type reactor pressure vessel (RPV) steel. A feature of this material is a high Ni content (> 1 wt.-%) in comparison with other RPV steels. Specimens from two WWER 1000 steels with different composition, one single neutron fluence each, were analysed in a previous investigation. It turned out that:
There is a monomodal size distribution of irradiation-induced defects with an average radius of about 1 nm.
The total volume fraction of defects is significantly higher than for WWER 440 steels, which had been investigated before in more detail also by other groups.]]></dc:description>

<dc:description><![CDATA[Measuring the resonance strengths of the 25Mg(p,γ)26Al reaction at energies of astrophysical interest poses a very difficult task for the usual prompt γ-ray detection method. Here we describe an alternative method in which targets are first irradiated and the produced 26Al nuclei are off-line counted by means of AMS. An overall efficiency of 4 × 10−5 could be achieved extracting AlO− from the ion source. For this purpose, a careful chemical treatment of the samples and the use of a gas filled magnet were necessary.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Alloys made of CrCoMo and CrNiMo are commonly used materials with UHMWPE (Ultra High Molecular Weight Polyethylene) as joint couple components in the orthopedic prosthesis. We have applied the plasma immersion ion implantation (PIII) to the samples made of these alloys to enhance their tribological properties and hence to make it possible to extend considerably their lifetime as joint components when implanted in humans. As a result, we obtained CrCoMo surface with 70% improvement in hardness and 10% in modulus of elasticity and CrNiMo surface with 250% improvement in hardness and practically no change in modulus. Peak nitrogen concentrations as high as 40% and 30% were achieved by nitrogen PHI for CrCoMo and CrNiMo, respectively. Formation Of gamma(N) phases in CrNiMo sample was clearly seen by XRD.

Gamma-Glutamyl semialdehyde (gammaGSA) is a product of hemin (Fe<SUP>3+</SUP>-protoporphyrin IX)-catalyzed oxidation of apolipoprotein B-100 (apoB- 100) proline and arginine residues. On reduction, gammaGSA forms 5-hydroxy-2-aminovaleric acid (HAVA). This report describes the application of sensitive HAVA assay, to characterize gammaGSA formation in LDL under normo- and hyperglycemic conditions, both in vitro and in vivo. In vitro studies revealed that apoB-100 proline and arginine residues are not oxidized to HAVA by HOCl or the myeloperoxidase/hydrogen peroxide (H<SUB>2</SUB>O<SUB>2</SUB>) oxidation system. Cu<SUP>2+</SUP>, Cu<SUP>2+</SUP>/H<SUB>2</SUB>O<SUB>2</SUB>, and Fe<SUP>2+</SUP> induced only minor HAVA formation. In contrast, the hemin oxidation system appeared reactive toward LDL apoB-100 proline and arginine residues. The resulting significant HAVA formation was specifically inhibited by a redox-inert ferric iron chelator. Glucose further enhanced hemin-induced increase in relative electrophoretic mobility of LDL and apoB-100 HAVAformation. In vivo we observed elevated concentrations of HAVA in LDL apoB-100 in patients with impaired glucose tolerance and with manifest diabetes mellitus. In conclusion, glucose promotes iron-mediated oxidation of apoB- 100 proline and arginine residues via a superoxide-dependent mechanism, thus rendering the LDL particles more atherogenic. The findings (a) identify a potential mechanism of enhanced atherogenesis in subjects with diabetes mellitus and (b) support the value of HAVA as a specific marker of LDL apoB-100 oxidation.]]></dc:description>

<dc:title><![CDATA[Die Erholung der sächsischen Talsperrenökosysteme von der atmosphärischen Versauerung im Vergleich zu hydrochemischen Trends im Einzugsgebiet der Talsperre Kleine Kinzig (Nordschwarzwald)]]></dc:title>
<dc:source><![CDATA[15. Limnologisches Gespräch des Zweckverbandes Wasserversorgung Kleine Kinzig (WKK), 20.10.2005, Alpirsbach-Reinerzau, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Aufgrund des enormen Ausstoßes an Schwefeldioxid und Stickoxiden sowie des basenarmen Grundgesteins von Erzgebirge und Vogtland litten zahlreiche sächsische Staugewässer etwa seit Mitte der 1960er Jahre unter der atmosphärischen Versauerung. Dies betraf auch einige Trink¬wassertalsperren. Nach der Wiedervereinigung wurden weder Kosten noch Aufwand gescheut, um geeignete Technologien zur Aufbereitung des weichen, sauren Rohwassers zu entwickeln, die Wasserwerke zu modernisieren und auf die Einhaltung der geforderten Grenzwerte einzustellen.
Innerhalb des letzten Jahrzehnts verringerten sich die Schwefeldioxid-Emissionen beträchtlich. Der Literatur zufolge gibt es große regionale Unterschiede bei der Erholung der Oberflächengewässer von der atmosphärischen Versauerung. Entsprechende Trends sind in vielen deutschen Mittelgebirgen nur schwach ausgeprägt oder überhaupt nicht nachweisbar. Dies begründet die Motivation, den Datenbestand der Landestalsperrenverwaltung Sachsen am Beispiel von sieben versauerten Talsperren und 22 Zuflüssen hinsichtlich der Trends ausge¬wählter hydrochemischer Parameter für 11 Jahre (1993-2003) mit dem Saisonalen Mann-Kendall Test statistisch auszuwerten und mit anderen Regionen zu vergleichen. Beispielsweise stehen im Nordschwarzwald für die Zuflüsse der Trinkwassertalsperre Kleine Kinzig entsprechende Datensätze aus den Jahren 1989 bis 2003 zur Verfügung. 
Der Vortrag stellt die charakteristischen Trends im Zusammenhang mit der regionalen Entwicklung der Emissions- und Depositionssituation und vor dem Hintergrund forstlicher Bodenschutzkalkung dar. Als Hauptfaktor für den in 85% der untersuchten sächsischen Gewässer signifikanten Konzentrationsrückgang von Protonen und Sulfat wird die Abnahme der Depositionsraten um mindestens Faktor 3 angesehen. In etwa 20% der Gewässer, bei denen die insgesamt applizierte Dolomitdosis im Einzugsgebiet 7 t ha-1 überschritt, fanden sich steigende Trends der Calcium- und/oder Magnesiumkonzentration, die jedoch nicht signifikant waren. Der direkte Beitrag der Bodenschutzkalkung zur Entsäuerung und nachhaltigen Erhöhung des Pufferungsvermögens der Oberflächengewässer wird als relativ gering eingeschätzt. Der starke Konzentrationsrückgang von Protonen und damit einhergehend von toxischen Aluminiumver¬bindungen bildet die Grundlage für eine Wiederbesiedelung der Gewässer durch säure¬empfindliche Organismen. Veränderungen in der Dominanzstruktur des Phytoplanktons gab es bereits in mehreren Talsperren im Vogtland. Dort hat sich auch gezeigt, dass mit dem Auftreten einer planktivoren Fischart extreme Schwankungen im Bestand bis hin zu Massensterben durch zeitweise Erschöpfung der Nahrungsressourcen einhergehen. Die Räuber-Beute-Effekte sowie episodisch auftretende Säureschübe können die Etablierung von größerer planktischer Filtrierer (z.B. Daphnien) stark verzögern.]]></dc:description>

<dc:description><![CDATA[The generation of negative He ions for acceleration at tandem accelerators requires an ion source with alkali vapor charge exchange canal. The diffusion of the Li or Rb vapor into the surrounding vacuum chamber limits the operation time of the ion source and increases the necessary maintenance. On the other hand, the modified rf ion source at the Rossendorf single ended 2 MV Van de Graaff accelerator has a life time of some thousands hours. The installation of this ion source inside the terminal of the Rossendorf 5 MV tandem accelerator would allow high-energy implantation of He ions in the energy range of 1-5 MeV without the difficulties of the charge-exchange canal. To reduce the risk for breaking of the ion source glass bottle under the pressure of the insulating gas a ceramic source bottle has been tested. First results of its operation at the 2 MV VdG are presented.]]></dc:description>

<dc:description><![CDATA[Intersubband (ISB) transitions in semiconductor quantum wells (QWs) can be employed for various mid-infrared optoelectronic devices. Presently there is strong interest to extend the available wavelength range into the near infrared, by using materials with a large conduction band offset. To achieve such short wavelengths thin QWs are required, where the first excited state inside the QW may lie higher than some state related to indirect valleys. Examples for such material systems are strained InGaAs/AlAs or lattice matched InGaAs/AlAsSb, both grown on InP. We have studied the ISB relaxation dynamics in multi QWs of both material systems by femtosecond pump-probe measurements. The transient transmission as a function of the pump-probe delay does not show a single-exponential decay, indicating a more complicated relaxation dynamics. This can be caused by transfer of electrons to X- or L- states in the QWs or the barriers. We will show results on samples with different QW thicknesses and compare them to simulations based on rate equations.]]></dc:description>

<dc:source><![CDATA[Optics Express 14(2006), 430-437]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[We demonstrate a rapid scanning high-resolution THz spectrometer capable of acquiring THz field transients with 1 ns duration without mechanical delay line. The THz spectrometer is based on two 1-GHz Ti:sapphire femtosecond lasers which are linked with a fixed repetition rate difference in order to perform high-speed asynchronous optical sampling. One laser drives a high-efficiency large-area GaAs based THz emitter, the other laser is used for electro-optic detection of the emitted THz-field. At a scan rate of 9 kHz a time resolution of 230 fs is accomplished. High-resolution spectra from 50 GHz up to 3 THz are obtained and water absorption lines with a width of 11 GHz are observed. The use of femtosecond lasers with 1 GHz repetition rate is essential to obtain rapid scanning and high time-resolution at the same time.]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[An attempt to synthesize superconducting MgB2 inter-metallic compound from the liquid state is presented. The process consists of two steps. In the first one, boron ions are implanted into a magnesium substrate. In the second one, the near-surface region of such system is melted by short, intense hydrogen plasma pulses without necessity of annealing in Mg vapor. A magnetically modulated microwave absorption method was used to detect superconducting regions in the obtained MgB2 layer. Percolation between nano-regions (islands) of MgB2 has not been observed. However, a superconducting state of the insulated islands has been experimentally proven with transition temperatures TC as high as 31 K.]]></dc:description>

<dc:date>2007</dc:date>
<dc:description><![CDATA[Structural and magnetic properties in Mn-implanted, p-type Si were investigated. High resolution structural analysis techniques such as synchrotron x-ray diffraction revealed the formation of MnSi1.7 nanoparticles already in the as-implanted samples. Depending on the Mn fluence, the size increases from 5  nm  to  20  nm upon rapid thermal annealing. No significant evidence is found for Mn substituting Si sites either in the as-implanted or annealed samples. The observed ferromagnetism yields a saturation moment of 0.21µB per implanted Mn at 10  K, which could be assigned to MnSi1.7 nanoparticles as revealed by a temperature-dependent magnetization measurement.]]></dc:description>

<dc:description><![CDATA[Lithium niobate containing erbium (Er:LiNbO3), which is often used as non-linear optical material, was studied by Rutherford backscattering spectroscopy (RBS)-channeling analysis and X-ray diffraction (XRD). The Er3+ doping was done by both bulk doping and by localised doping. The studied samples were virgin Er:LiNbO3 wafers, and annealed proton exchange (APE) treated wafers in order to increase the refractive index in the surface layer and to create the planar optical waveguides. Moreover, erbium ions were introduced into the surface of pure LiNbO3 wafers by Er-moderate temperature localised doping. The APE:Er:LiNbO3 samples showed modifications of the crystal lattice compared to the virgin Er:LiNbO3; the Er localised doping samples even exhibited the tendency to form an amorphous surface layer in which the Er ions were incorporated.]]></dc:description>

<dc:source><![CDATA[DPG Frühjahrstagung, 13.-15.3.2006, Heidelberg, Deutschland]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Bei der Radiotherapie von Tumoren erlauben Ionenstrahlen auf Grund ihrer physikalischen und biologischen Eigenschaften ein höheres Maß an Präzision und Wirksamkeit als die konventionellen Strahlenmodalitäten, Photonen und Elektronen. Ein in-situ Monitoring der Dosisapplikation ist deshalb für die Qualitätssicherung der Ionentherapie in hohem Maße wünschenswert. Das einzige gegenwärtig bekannte, dafür geeignete Verfahren ist die in-beam Positronen-Emissionstomographie (PET). Dabei werden während der Tumorbestrahlungen Annihilationsereignisse registriert, die in Folge des Zerfalls von Positronenemittern auftreten, welche durch nuklare Wechselwirkungen zwischen den Projektilen des Therapiestrahles und den Atomkernen des Gewebes erzeugt werden. In die experimentelle Ionentherapie-Anlage an der Gesellschaft für Schwerionenforschung Darmstadt wurde ein in-beam PET-Scanner integriert und die Methode erstmals klinisch angewendet. An dieser Anlage wurden seit 1997 etwa 300 Patienten, vornehmlich mit stahlenresistenten Tumoren in komplizierten anatomischen Positionen im Kopf-Hals-Bereich mit Kohlenstoff-Ionenstrahlen behandelt. Alle Bestrahlungen wurden mit PET kontrolliert.Die nunmehr vorliegenden Erfahrungen erlauben gesicherte Aussagen zum Potential der in-beam PET für die Qualitätssicherung der Ionentherapie.]]></dc:description>

<dc:description><![CDATA[Low energy ion beams are widely used to alter the surface properties of semiconductors. We have used two different ways to create lateral nanostructures, either using an artificial patterning by a focused ion beam or by a tilted non-focused ion beam achieving a self-organizing ripple formation. X-ray grazing-incidence diffraction is a powerful tool to investigate such lateral nano-structures. Choosing the angle of incidence smaller or slightly larger as the critical angle of total external reflection one can probe the fine structure of an in-plane Bragg diffraction in a depth between about 5 to several 100 nm.]]></dc:description>

<dc:description><![CDATA[At FZR an integral axisymmetric finite element model has been developed for simulat-ing the late phase of core melt down scenarios in a RPV. The model allows for the calculation of the failure time and the failure mode of a vessel with a heated melt pool. In the thermal submodel the transient temperature field of the melt and of the vessel wall is evaluated. This can be done either with a CFD model or with the Effective Conduction Convection Model (ECCM). Within the mechanical submodel the viscoplastic deformation of the vessel wall is simulated.

<dc:description><![CDATA[At FZR an integral axisymmetric finite element model has been developed for simulat-ing the late phase of core melt down scenarios in a RPV. The model allows for the calculation of the failure time and the failure mode of a vessel with a heated melt pool. In the thermal submodel the transient temperature field of the melt and of the vessel wall is evaluated. This can be done either with a CFD model or with the Effective Conduction Convection Model (ECCM). Within the mechanical submodel the viscoplastic deformation of the vessel wall is simulated. By use of the material damage the failure time and position can be deter-mined. An additional mechanical submodel is used to evaluate the melt pool deformation.

<dc:description><![CDATA[Ion implantation and subsequent thermal annealing are the standard processes for the electrical doping of semiconductors. Ion implantation is characterized by fast ballistic processes which lead to the deposition of the implanted atoms and to displacements of the target atoms. After the fast relaxation of the displaced atoms a (meta)stable defect structure is formed. Long-term thermally activated processes, especially during thermal annealing, cause defect reduction, rearrangement, and migration. In my talk I will show that computer simulations on the atomic level are a useful tool for the theoretical description of the  different physical processes occurring during ion implantation and thermal annealing. The ballistic processes are simulated by the Crystal-TRIM code which is based on the binary collision approximation (BCA). This code is part of different process simulators. Classical molecular dynamics (MD) simulations are employed to investigate defect migration over a period of  10 - 100 ns. The defect diffusivity as well as the microscopic migration mechanisms are studied.  A combination of BCA and MD simulations is used to determine the complex defect morphology after the fast relaxation processes are finished. This method allows the effective calculation of the total number and the depth distribution of different defect species (e.g. isolated vacancies and self-interstitials as well as more complex defects) formed on average per incident ion.]]></dc:description>

<dc:source><![CDATA[Physical Review B 74(2006), 045208]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[High quality single crystals of ZnO in the as-grown and N+ ion-implanted states have been investigated using a combination of three experimental techniques - namely, positron lifetime/slow positron implantation spectroscopy accompanied by theoretical calculations of the positron lifetime for selected defects, temperature-dependent Hall (TDH) measurements and deep level transient spectroscopy (DLTS). The positron lifetime in bulk ZnO is measured to be (151 + 2) ps and that for positrons trapped in defects (257 + 2) ps. On the basis of theoretical calculations the latter is attributed to Zn+O divacancies, existing in the sample in both neutral and single negative charge states, and not to the Zn vacancy proposed in previous experimental work. From TDH measurements the concentrations of negatively-charged and neutral Zn+O divacancies are estimated to lie between 4 × 1015 and 6.3 × 1016 cm-3. DLTS revealed the creation of the defect E1 and an increase in concentration of the defect E3 after N+ ion implantation. Furthermore, a p-conducting layer is formed at the surface after the implantation/annealing procedure that can be used to inject holes during a DLTS measurement. In this way, the acceptor traps A2 and A3 with thermal activation energies of about 150 and 280 meV, respectively, have been detected for the first time by DLTS.]]></dc:description>

<dc:description><![CDATA[A coupled rate theory model of defect evolution and Cu clustering was introduced as a basis for the rate theory upgrade with coherency and solute content of clusters. The coupling is essentially due to the operation of Cu clusters as vacancy sinks. The model was transferred to FORTRAN code and calibrated using results of small-angle neutron scattering (SANS) experiments for a Cu-enriched (0.42% Cu) iron model alloy irradiated up to two neutron fluences. Extensions of the model to take into account size dependent cluster composition are proposed.]]></dc:description>

<dc:description><![CDATA[Oxidative modification of LDL is regarded as a crucial event in atherogenesis. Data concerning the role of circulating oxidized LDL (oxLDL) in the development of atherosclerosis are scarce. One reason for this is the shortage of methods for direct assessment of metabolism of oxLDL in vivo. We report a new methodology for labeling of both native LDL (nLDL) and oxLDL with the positron emitter fluorine-18 (18F; t½=109.7 min) by conjugation with SH-reactive N-[6-(4-[<SUP>18</SUP>F]fluorobenzylidene)-aminooxyhexyl]maleimide ([<SUP>18</SUP>F]MHAA) and the use of <SUP>18</SUP>F-labeled LDL particles in dynamic PET studies in male Kyoto-Wistar rats. For labeling experiments, pools of chemically and biochemically well characterized human nLDL and oxLDL (modified by hemin/H<SUB>2</SUB>O<SUB>2</SUB>) particles, respectively, were used. Radiosynthesis of [<SUP>18</SUP>F]MHAA started with the preparation of [<SUP>18</SUP>F]fluorobenzaldehyde. In a one-pot procedure N-(6-aminooxyhexyl)maleimide was added to the generated aldehyde and after-wards [<SUP>18</SUP>F]MHAA was isolated by HPLC. Preparation of [<SUP>18</SUP>F]MHAA was achieved within 70 min with radiochemical yields of 34±5% (corrected for decay) and purity of >96%. [<SUP>18</SUP>F]MHAA was shown to react efficiently and selectively with SH-groups of various peptides and proteins under mild conditions. LDL labeling with [<SUP>18</SUP>F]MHAA resulted in radiochemical yields of 20±10% (corrected for decay) and specific radioactivity of 150-300 GBq/µmol. Radiolabeling of nLDL and oxLDL using [<SUP>18</SUP>F]MHAA caused neither additional oxidative structural modifications of LDL lipids and proteins nor alteration of their biological activity and functionality in vitro, respectively. The method was evaluated with respect to uptake of 18F-labeled LDL in human hepatoma cells (HepG2) and monocytes/macrophages (THP-1), respectively. Biodistribution studies in rats revealed high in vivo stability for the <SUP>18</SUP>F-labeled LDL. The metabolic fate of the <SUP>18</SUP>F-labeled LDL in vivo was delineated by dynamic PET studies using a dedicated small animal tomograph (spatial resolution of <2 mm). Data were compared to former studies using the NH<SUB>2</SUB>-reactive <SUP>18</SUP>F-labeling agent N-succinimidyl-4-[<SUP>18</SUP>F]fluorobenzoate.

<dc:description><![CDATA[Oxidative modification of LDL is regarded as a crucial event in atherogenesis. Data concerning the role of circulating oxidized LDL (oxLDL) in the development of atherosclerosis are scarce. One reason for this is the shortage of methods for direct assessment of metabolism of oxLDL in vivo. We report a new methodology for labeling of both native LDL (nLDL) and oxLDL with the positron emitter fluorine-18 (18F; t½=109.7 min) by conjugation with SH-reactive N-[6-(4-[<SUP>18</SUP>F]fluorobenzylidene)-aminooxyhexyl]maleimide ([<SUP>18</SUP>F]MHAA) and the use of <SUP>18</SUP>F-labeled LDL particles in dynamic PET studies in male Kyoto-Wistar rats. For labeling experiments, pools of chemically and biochemically well characterized human nLDL and oxLDL (modified by hemin/H<SUB>2</SUB>O<SUB>2</SUB>) particles, respectively, were used. Radiosynthesis of [<SUP>18</SUP>F]MHAA started with the preparation of [<SUP>18</SUP>F]fluorobenzaldehyde. In a one-pot procedure N-(6-aminooxyhexyl)maleimide was added to the generated aldehyde and after-wards [<SUP>18</SUP>F]MHAA was isolated by HPLC. Preparation of [<SUP>18</SUP>F]MHAA was achieved within 70 min with radiochemical yields of 34±5% (corrected for decay) and purity of >96%. [<SUP>18</SUP>F]MHAA was shown to react efficiently and selectively with SH-groups of various peptides and proteins under mild conditions. LDL labeling with [<SUP>18</SUP>F]MHAA resulted in radiochemical yields of 20±10% (corrected for decay) and specific radioactivity of 150-300 GBq/µmol. Radiolabeling of nLDL and oxLDL using [<SUP>18</SUP>F]MHAA caused neither additional oxidative structural modifications of LDL lipids and proteins nor alteration of their biological activity and functionality in vitro, respectively. The method was evaluated with respect to uptake of 18F-labeled LDL in human hepatoma cells (HepG2) and monocytes/macrophages (THP-1), respectively. Biodistribution studies in rats revealed high in vivo stability for the <SUP>18</SUP>F-labeled LDL. The metabolic fate of the <SUP>18</SUP>F-labeled LDL in vivo was delineated by dynamic PET studies using a dedicated small animal tomograph (spatial resolution of <2 mm). Data were compared to former studies using the NH<SUB>2</SUB>-reactive <SUP>18</SUP>F-labeling agent N-succinimidyl-4-[<SUP>18</SUP>F]fluorobenzoate. In conclusion, <SUP>18</SUP>F-labeling of LDL and the use of small animal PET provide a valuable tool for mapping sites of both nLDL and oxLDL metabolism in animal models in vivo.]]></dc:description>

<dc:description><![CDATA[Substances of various chemical structures can be labelled with appropriate positron emitting isotopes and applied as tracer compounds in PET examinations. Using dynamic data acquisition protocols, time-activity curves of radioactivity uptake in organs can be derived and the measurements of tissue tracer concentrations can be translated into quantitative values of tissue function. However, analysis of metabolites of these tracers regarding their nature and distribution in the living organism is an essential need for the quantitative analysis of PET measurements. In addition, metabolite analysis contributes to the interpretation of the images obtained as well as to the identification of pathological changes in metabolic pathways. This paper reports on representative examples of radiolabelled compounds which might be of importance in food science (e.g., amino acids, polyphenols, and model compounds for advanced glycation end products (AGEs)). Typical procedures of analysis (radio-HPLC, radio-TLC) including pre-analytical sample preparation are described. Specific challenges of the method, e.g., trace amounts of radiolabelled compounds and the influence of the often very short half-lives of positron-emitting nuclides used are highlighted. Representative results of analyses of plasma, urine, and tissue samples are presented and discussed in terms of the metabolic fate of the tracers.]]></dc:description>

<dc:description><![CDATA[This paper contributes to the studies of physical properties of metastable Fe-Cr phases which have been discovered recently in the thin films deposited from the hyperthermal Fe and Cr particle beams. The electrical resistance and the magnetic remanence are correlated with the crystallographic parameters and phase composition of the samples. It is demonstrated that the focused ion-beam induced phase transformation in the unusual metastable Fe-Cr alloys can be used for the fabrication of ferromagnetic arrays.]]></dc:description>

<dc:description><![CDATA[The influence of highly functionalized saccharic and phenolic polymers that are formed in the process of hydrothermal wood degradation on the uranium(VI) adsorption onto metamorphic rocks and sediments from the Saxon uranium mining sites Schlema-Alberoda and Konigstein was investigated in a laboratory study. Uranium(VI) adsorption from a simulated mine water takes place on the majority of rocks and sediments such as granite, gneiss, basalt, sandstone and clay marl. Exceptions are phyllite and clay stone that do not bind any uranium from the mine water. Polymeric wood degradation products such as fragments of celluloses and lignin increase the uranium(VI) adsorption whereas the presence of saccharic and phenolic monomers (vanillic acid and gluconic acid) leads to a lower adsorption.]]></dc:description>

<dc:description><![CDATA[The intermetallic compound Pr(1-x-y)La(x)Pb(y)Te shows a wide spectrum of physical phenomena. Depending on the metallurgical composition as function of x and y, the compound changes its behavior from nuclear magnetic order to super- or semiconductivity. In addition, there are interesting interplay effects between these ground states. In consequence, Pr(1-x-y)La(x)Pb(y)Te may serve as an interesting material for quantum-computing applications. In this contribution, we focus on our recent investigation of the magnetic properties of Pr(1-y)Pb(y)Te. We present data of the magnetisation taken at 1.8 K < T < 350 K for various compositions y = 0, 90, 99, 99.9 %, i.e. turning the system from a van Vleck paramagnet, y = 0,  into a doped semiconductor, y = 99.9 %.]]></dc:description>

<dc:source><![CDATA[Macromolecules 39(2006)6, 2162-2171]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Recently, two different groups have reported independently, that the mobility of field-effect transistors made from regioregular poly(3-hexylthiophene) (P3HT) increases strongly with molecular weight. Two different models were presented, one proposing carrier trapping at grain boundaries and the second putting emphasis on different conformation and packing of the polymer chains in the thin layers. 
Here, we present the results of detailed investigations of powders and thin films of deuterated P3HT fractions with different molecular weight. For powder samples, gel permeation chromatography (GPC), differential scanning calorimetry (DSC) and X-ray diffraction (XRD) were used to investigate the structure and crystallization behaviors of the polymers. The GPC investigations show that all weight fractions possess a rather broad molecular weight distribution. DSC measurements revealed a strong decrease of the crystallization temperature and, most important, a significant decrease of the degree of crystallinity with decreasing molecular weight. In order to study the structure of thin layers in lateral and vertical directions, both transmission electron microscopy (TEM) and X-ray grazing incidence diffraction (GID) were utilized. These methods show that thin layers of the low molecular weight fraction consist of well-defined crystalline domains embedded in disordered matrix. In contrast, films of the high molecular weight fraction exhibit partially-ordered domains throughout the whole sample area. We propose that the transport properties of layers prepared from fractions of poly(3-hexylthiophene) with different molecular weight is largely determined by the crystallinity of the samples and not by the perfection of the packing of the chains in the individual crystallites.]]></dc:description>

<dc:description><![CDATA[The magnetic properties of both interacting and non-interacting iron nanoparticle systems were investigated by means of SQUID magnetometry. Both nanoparticle systems were produced by ion beam synthesis. For this purpose Fe+ was implanted into diamagnetic LaAlO3 substrates with a fluence of 6×1016 cm-2 at an energy of 120 keV at either 400°C or 800°C. It is observed that for the lower (higher) temperature a non-interacting (interacting) nanoparticle ensemble is created. The size distribution of the nanoparticles is studied by transmission electron microscopy. The memory effects in these systems were investigated by field-cooling and zero field-cooling magnetization measurements. Both analysis methods should help to settle the controversy whether the interaction between superparamagnetic particles or their size distribution is responsible for the memory effect [1, 2].

<dc:description><![CDATA[Radiochemistry with the short-lived positron emitter carbon-11 (t<SUB>1/2</SUB> = 20.38 min) represents special challenges in terms of synthesis time and the labelling techniques. The recent developments in carbon-11 radiochemistry have steadily expanded the number of carbon-11 labelled compounds. The review wants to address selected chemical and technical aspects of carbon-11 chemistry based on the readily available labelling precursors [<SUP>11</SUP>C]methyl iodide and, to some lower extent, [<SUP>11</SUP>C]methyl triflate. Special emphasis is attributed to heteroatom methylation reactions and <SUP>11</SUP>C-C bond formations.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Detailed experimental data obtained at the TOPFLOW facility for steam-water vertical pipe flow were used to test the complex interaction of local bubble distributions, bubble size distributions and local heat and mass transfer. Steam is injected into sub-cooled water and condenses during the upwards flow. The model considers a large number of bubble classes (50). This allows the investigation of the influence of the bubble size distribution. The results of the simulations show a good agreement with the experimental data. The condensation process is clearly slower, if large bubbles are injected (4 mm holes). Also bubble break-up has a strong influence on the condensation process because of the change of the interfacial area. Some unsureness arises from the unknown interfacial area for large bubbles and possible uncertainties of the heat transfer coefficient.]]></dc:description>

<dc:description><![CDATA[The ability of hydroxyapatite Ca10(OH)2(PO4)6 (HAP) to immobilize metal ions, particularly lanthanides and actinides, is well known. The long-term stability of this fixation is proven by natural analogue studies. Thus, HAP is a potential filling material in engineered barriers in abandoned mining areas as well as in the near-field of un-derground repositories for nuclear and toxic waste.
The interaction of U(VI) with HAP was studied in batch and unsaturated column experiments and by time-resolved laser-induced fluorescence spectroscopy (TRLFS). We investigated a seepage water from Schlema (Saxony) with a uranium concentra-tion of 10-5 M and a synthetic HAP packed in a matrix of purified quartz sand.
In common batch sorption experiments, a strong interaction of uranium with the HAP surface was observed. The sorption of uranyl ions onto phosphate groups is eventually as important as their sorption onto silanol groups, outweighing the low phosphate content. From the interpretation of the TRLFS spectra, two surface spe-cies could be distinguished. On the basis of their fluorescence decay time and the shift of the peak maxima related to the free uranyl ion, these two species could be associated with uranium adsorbed to phosphate and silanol surface groups, respec-tively.
The breakthrough curves (BTCs), measured at different vertical positions of the column, exhibit a strong retardation of uranium compared to the conservative tracer. The breakthrough (i.e., exceeding 50 % of the starting concentration) occurs after about 30 pore volumes. However, the elution part of the BTCs features a pro-nounced tailing. The release of uranium is controlled by two processes of different rates. We assign the faster sorption/desorption scheme to the uranyl silanol surface species, exhibiting an almost full reversibility. The second observed process creating the long and pronounced tailing in the BTCs can be explained by the much stronger binding of the uranyl moiety to the phosphate sites.]]></dc:description>

<dc:description><![CDATA[The ability of hydroxyapatite Ca10(OH)2(PO4)6 (HAP) to immobilize metal ions, particularly lanthanides and actinides, is well known. The long-term stability of this fixation is proven by natural analogue studies. Thus, HAP is a potential filling material in engineered barriers in abandoned mining areas as well as in the near-field of un-derground repositories for nuclear and toxic waste.
The interaction of U(VI) with HAP was studied in batch and unsaturated column experiments and by time-resolved laser-induced fluorescence spectroscopy (TRLFS). We investigated a seepage water from Schlema (Saxony) with a uranium concentra-tion of 10-5 M and a synthetic HAP packed in a matrix of purified quartz sand.
In common batch sorption experiments, a strong interaction of uranium with the HAP surface was observed. The sorption of uranyl ions onto phosphate groups is eventually as important as their sorption onto silanol groups, outweighing the low phosphate content. From the interpretation of the TRLFS spectra, two surface spe-cies could be distinguished. On the basis of their fluorescence decay time and the shift of the peak maxima related to the free uranyl ion, these two species could be associated with uranium adsorbed to phosphate and silanol surface groups, respec-tively.
The breakthrough curves (BTCs), measured at different vertical positions of the column, exhibit a strong retardation of uranium compared to the conservative tracer. The breakthrough (i.e., exceeding 50 % of the starting concentration) occurs after about 30 pore volumes. However, the elution part of the BTCs features a pro-nounced tailing. The release of uranium is controlled by two processes of different rates. We assign the faster sorption/desorption scheme to the uranyl silanol surface species, exhibiting an almost full reversibility. The second observed process creating the long and pronounced tailing in the BTCs can be explained by the much stronger binding of the uranyl moiety to the phosphate sites.]]></dc:description>

<dc:description><![CDATA[Stratified two-phase flow regimes can occur in the main cooling lines of Pressurized Water Reactors, Chemical plants and Oil pipelines. A relevant problem occurring is the development of wavy stratified flows, which can lead to slug generation. In the last decade, stratified flows have increasingly been modelled with computational fluid dynamics (CFD) codes. In CFD, closure models are required that must be validated. Recent improvements of the multiphase flow modelling in the ANSYS CFX code, now make it possible to simulate these mechanisms in detail. In order to validate existing and further developed multiphase flow models, a high spatial and temporal resolution of measurement data are required. For the experimental investigation of co-current air/water flows, the HAWAC (Horizontal Air/Water Channel) was built. The channel allows in particular the study of air/water slug flow under atmospheric pressure. Parallel to the experiments, CFD calculations were carried out. The two-fluid model was applied with a special turbulence damping procedure at the free surface. An Algebraic Interfacial Area Density (AIAD) model based on the implemented mixture model was introduced, which allows the detection of the morphological form of the two-phase flow and the corresponding switching via a blending function of each correlation from one object pair to another. As a result, this model can distinguish between bubbles, droplets and the free surface using the local value of the volume fraction of the liquid phase. The behaviour of slug generation and propagation was qualitatively reproduced by the simulation, while local deviations require a continuation of the work.]]></dc:description>

<dc:source><![CDATA[Radiochimica Acta 74(1996), 219]]></dc:source>
<dc:date>1996</dc:date>
<dc:description><![CDATA[Extended X-ray absorption fine structure (EXAFS) analysis was performed on uranyl orthosilicate, (UO2)(2)SiO4 . 2H(2)O, and uranium(VI) sorbed onto silicic acid and silica gel. Uranyl orthosilicate was investigated as a reference for EXAFS studies of similar but non-crystalline uranium, oxygen, and silicon containing samples. Fitting the EXAFS spectrum yields the following distances for the first four coordination shells of uranium: U-O-ax = 1.79 Angstrom, U-O-eq = 2.38 Angstrom, U-Si = 3.16 Angstrom, and U-U = 3.88 Angstrom. These values agree well with results from single-crystal X-ray diffraction (XRD) measurements. Structural parameters of light elements such as oxygen and silicon at distances greater than 3.5 Angstrom could not he detected without a priori knowledge of their presence. The EXAFS spectra of uranyl species sorbed at pH 4 onto silicic acid and silica gel are identical indicating similar uranyl coordination. The main characteristic of the surface species are two well-separated oxygen coordination shells in the equatorial uranyl plane at 2.27 and 2.50 Angstrom. The results of the EXAFS analysis favor the interpretation of the uranyl surface species as an inner-sphere, mononuclear, bidentate complex.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The central distinguishing feature of positron emission tomography (PET) is its ability to investigate quantitatively regional cellular and molecular transport processes in vivo with good spatial resolution. This review wants to provide a concise overview of the established principles underlying quantitative data evaluations of the acquired PET images. Especially, the compartment modelling framework is discussed on which virtually all quantification methods utilized in PET are based. The aim of the review is twofold: first, to provide the reader with an idea of the theoretical framework and mathematical tools and second, to enable an intuitive grasp of the possibilities and limitations of a quantitative approach to PET data evaluation. This should facilitate an understanding of how PET measurements translate into quantities such as regional blood flow, volume of distribution, and metabolic rates of specific substrates.]]></dc:description>

<dc:source><![CDATA[9th International Conference on Material Issues inIN Design, Manufactoringand Operation Peration of Nuclear Power Plants Equipment, 05.-09.06.2006, St. Petersburg, Russia]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The operation of the four Greifswald units (VVER-440/230) finished in 1991 after 12  15 years of operation. The investigation of RPV material from the decommissioned Greifswald NPP offers the possibility to evaluate the state of the standard RPV design and to assess the quality of prediction rules and assessment tools. The different operation conditions (irradiated, annealed, and re-irradiated) are a special advantage of the research program.
In autumn 2005 the first trepans (diameter 120 mm) were gained from the unit 1 of this NPP. A new drilling machine was developed and adopted to the actual plant conditions. The drilling machine allows the following remote controlled actions:

	Labeling the position and orientation of the trepan
	Drilling the trepan and ejection of the trepan into the RPV
	Closing the hole in the RPV

Details of the trepanning procedure will be given. 
Fluence calculations using the code TRAMO were based on pin-wise time dependent neutron sources and an updated nuclear data base (ENDF/B-VI release 8). The neutron and gamma fluence spectra were determined at the trepan positions. The integral neutron fluence at the inner RPV wall near the critical weld was found to 4.64* 10^18 n*cm-2. The maximum fluence at the RPV is 50 % higher. In addition, it could be shown that the fluence at the designated reference positions can be neglected (3 orders of magnitude smaller).  The gamma fluence was calculated to 1.9 *10^20 photons* cm-2 at the critical weld with a similar axial distribution.
The experimental determination of the neutron fluence was based on Niobium activity measurements. The RPV material contains Niobium as trace element. The analysis of the Nb-content is carried out by ICP-MS (inductive coupled plasma mass spectrometry) after dissolution of the material sample. The radiochemical isolation of Nb was done by an anion exchange column. By this separation all other elements were removed. 
The measurement of the 93mNb activity is realized by Liquid Scintillation Spectrometry (LSC).  Parallel the chemical yield is determined by the above mentioned ICP-MS method.]]></dc:description>

<dc:title><![CDATA[Retrospective dosimetry of Greifswald VVER 440 RPV: Fluence calculations and Nb based fluence measurements]]></dc:title>
<dc:source><![CDATA[9th International Conference on Material Issues in Design, Manufactoringand Operation Peration of Nuclear Power Plants Equipment, 06.-09.06.2006, St. Petersburg, Russia<br>Proceedings, 241-247]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The operation of the four Greifswald units (VVER-440/230) finished in 1991 after 12  15 years of operation. The investigation of RPV material from the decommissioned Greifswald NPP offers the possibility to evaluate the state of the standard RPV design and to assess the quality of prediction rules and assessment tools. The different operation conditions (irradiated, annealed, and re-irradiated) are a special advantage of the research program.
In autumn 2005 the first trepans (diameter 120 mm) were gained from the unit 1 of this NPP. A new drilling machine was developed and adopted to the actual plant conditions. The drilling machine allows the following remote controlled actions:

	Labeling the position and orientation of the trepan
	Drilling the trepan and ejection of the trepan into the RPV
	Closing the hole in the RPV

Details of the trepanning procedure will be given. 
Fluence calculations using the code TRAMO were based on pin-wise time dependent neutron sources and an updated nuclear data base (ENDF/B-VI release 8). The neutron and gamma fluence spectra were determined at the trepan positions. The integral neutron fluence at the inner RPV wall near the critical weld was found to 4.64* 10^18 n*cm-2. The maximum fluence at the RPV is 50 % higher. In addition, it could be shown that the fluence at the designated reference positions can be neglected (3 orders of magnitude smaller).  The gamma fluence was calculated to 1.9 *10^20 photons* cm-2 at the critical weld with a similar axial distribution.
The experimental determination of the neutron fluence was based on Niobium activity measurements. The RPV material contains Niobium as trace element. The analysis of the Nb-content is carried out by ICP-MS (inductive coupled plasma mass spectrometry) after dissolution of the material sample. The radiochemical isolation of Nb was done by an anion exchange column. By this separation all other elements were removed. 
The measurement of the 93mNb activity is realized by Liquid Scintillation Spectrometry (LSC).  Parallel the chemical yield is determined by the above mentioned ICP-MS method.]]></dc:description>

<dc:source><![CDATA[Landbauforschung Volkenrode 55(2005), 139-148]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In the past, the chemistry of uranium was focused on its mining and milling for production of high pure uranium compounds as initial matter of reactor fuel elements for energy production and breeding of plutonium for weapons production. In this sense, the recovery of uranium and plutonium from the used reactor fuel elements was also technical realized. The increasing input into bio-sphere by uranium mining and milling and industrial processes like production of cement, fossil fuels, and fertilizers has led to the realization of the importance of environmental chemistry of uranium. Starting from uranium content in geo-and bio-systems, about the chemical behavior - the speciation of uranium - is reported in selected environmental compartments like seepage water, bacteria, and plants. The results obtained
by various spectroscopic methods show that the speciation of uranium is dominated in surface waters by uranyl carbonate complex in opposite to the speciation in bacteria and p!  lants. In these compartments the speciation is dominated by binding of uranium on carboxylic and phosphorous containing functional groups.]]></dc:description>

<dc:source><![CDATA[Surface &amp; Coatings Technology 195(2005), 258-263]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[A significant wear reduction by several orders of magnitude is the common result for austenitic stainless steels after energetic nitrogen implantation at medium temperatures around 380 °C. In contrast, martensitic stainless steels are rarely investigated. In this investigation, one steel grade, stainless steel AISI 630/DIN 1.4542, is treated using low energy nitrogen implantation at 380 and 600 °C, high voltage nitrogen plasma immersion ion implantation (PIII) and combined carbon/nitrogen PIII at 380 °C. Using PIII, an expanded martensitic lattice extending several micrometers into the sample was observed, whereas Fe4N and CrN were formed after low energy implantation at 380 and 600 °C, respectively. All samples show a hardness of up to 2000 HV and a wear reduction by two orders of magnitude. Additional metallographic cross-sections confirm the microstructure derived from XRD data.]]></dc:description>

<dc:description><![CDATA[When performing nitriding of stainless steels, there is a decrease or even complete depletion of chromium in the nitrogen rich region just beneath the surface, inhibiting the formation of passivated Cr oxide layer, beneficial to withstand corrosive attacks and Cr/Fe nitrides, responsible for hardness enhancement. To overcome this problem, a hybrid technique was used, consisting of depositing a thin chromium film on steel surface and then bombarding it with nitrogen ions. By a complex recoil process, chromium atoms are implanted into the steel matrix. Plasma immersion ion implantation (PIII) was used in this bombardment. The new Cr-rich layer allows the formation of Cr oxides and nitrides. Treated surfaces were characterized by Auger electron spectroscopy (AES) and conversion electron Mossbauer spectroscopy (CEMS), showing formation of a new Cr-rich layer. (c) 2005 Elsevier B.V.

<dc:source><![CDATA[Biofilm II, 23.-24.03.2006, Leipzig, Deutschland]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[A biofilm of Pseudomonas stutzeri was cultured in a annular rotating reactor /1/ at near-neutral pH conditions on glass slides. After reaching a mature confluent biofilm uranium(VI) was added to the nutrient solution to obtain a final uranium(VI) concentration of 5 ´ 10-6 M. The resulting biofilm was studied by Confocal Laser Scanning Microscopy (CLSM) and a biofilm thickness of 43 µm was recorded. Particles of approximately 5 µm were detected in the biofilm. These particles were excited by an diode laser with an excitation wavelength of 405 nm and the resulting fluorescence signal was recorded. Two kinds of flourescence signals were detected. One with a characteristic fluorecence signal in the range of 490 to 560 nm which is indicative for U(VI) /2/ and a second one with a fluorescence signal from 420 to 470 nm. Since U(IV) requires an excitation wavelength of 245 nm and shows a completely different fluorescence spectrum the formation of uranium(IV) particles was ruled out. However, based on UV-vis measurements of U(V) containing standard solutions these signals were interpreted as U(V) species, indicating that redox processes must have occured within the biofilm.]]></dc:description>

<dc:title><![CDATA[Growth of sputter-deposited Ni-Ti thin films: effect of a SiO<SUB>2</sub> buffer layer]]></dc:title>
<dc:source><![CDATA[Applied Physics A 84(2006)3, 285-289]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[In-situ x-ray diffraction (XRD) during the growth of Ni-Ti thin films was chosen in order to investigate their texture development using a deposition chamber installed at a synchrotron radiation beamline. Near-equiatomic films were co-sputtered from Ni-Ti and Ti targets. The texture evolution during deposition is clearly affected by the substrate type and the ion bombardment of the growing film. On naturally oxidized Si(100) substrates the NiTi B2 phase starts by stacking onto (h00) planes, and as the thickness increases evolves into a (110) fiber texture. For the deposition on thermally oxidized Si(100) substrates, this pronounced cross-over is only observed when a substrate bias voltage (-45 V) is applied. The oxide layer plays an important role on the development of the (100) orientation of the B2 phase during deposition on heated substrates (≈ 470ºC). If this layer is not thick enough (naturally oxidized Si substrate) or if a bias voltage is applied, a cross-over and further development of the (110) fiber texture is observed,which is considered as an orientation that minimizes surface energies. Electrical resistivity measurements showed different behaviour during phase transformation for the NiTi film deposited on thermally oxidized Si without bias and those on thermally oxidized Si(100) with bias and on naturally oxidized Si(100) without bias. This is related to stresses resultant from the fact that the NiTi films are attached to the substrates as well as with the existence of distinct textures.]]></dc:description>

<dc:description><![CDATA[The preferred orientation and thermal stability of MAX phase (M: early transition metal; A: A group element; X: C and/or N) Ti2AlN thin films sputtered onto MgO(111) and Al2O3(0001) substrates have been investigated by in situ x-ray diffraction and Rutherford backscattering (RBS). Low-temperature deposition results in epitaxial growth with inclined basal planes. An increased substrate temperature changes the preferred orientation to a parallel basal plane growth. In contrast to high bulk thermal stability, thin films decompose in vacuum already at 800°C by outward Al diffusion, followed by de-twinning of the remaining Ti2N slabs and concurrent TiN and Ti4AlN3 formation.]]></dc:description>

<dc:description><![CDATA[Understanding the migration behavior of actinides is important for the reliable long-term risk assessment of potential nuclear waste repositories. Depending on geochemical conditions different materials and processes can influence the behavior of such pollutants in natural aquifer systems. Humic acids (HA) comprise an important part of natural organic materials. HA are soluble in the pH range of natural waters and have the ability for complex and colloid formation. Due to these properties HA can affect the speciation of actinide ions, and therefore, their migration in the environment. In the present study we investigated the influence of HA on the U(VI) sorption onto kaolinite. 
Results from our previous batch experiments were combined with spectroscopic measurements to obtain molecular-level information on the interaction of U(VI) with HA and kaolinite (KGa-1b) in natural systems.   
From our batch experiments resulted that the sorption of U(VI) on kaolinite is influenced by experimental conditions such as pH, U(VI) concentration, CO2 presence and HA concentration. HA affects U(VI) adsorption onto kaolinite over the entire pH range. At pH < 5 the presence of HA enhances the U(VI) uptake relative to the HA-free system due to the formation of additional binding sites for U(VI). In the 	pH range between pH 5 and pH 8.5 the U(VI) sorption decreases in the presence of HA because of desorption of HA from the kaolinite surface resulting in the formation of dissolved U(VI)-HA complexes. At pH > 8.5 uranium sorption increases again relative to the HA-free system. Possibly, ternary U(VI)-humate complexes, e.g. uranyl-carbonato-humate complexes, are formed, which can interact with the kaolinite surface and therefore, enhance the U(VI) sorption onto kaolinite in the presence of HA in this pH region.
We used time-resolved laser-induced fluorescence spectroscopy (TRLFS) in order to characterize the species of U(VI) adsorbed onto kaolinite in the absence and presence of HA. Two adsorbed U(VI) surface species on kaolinite were identified in the pH range of pH 5.0 to pH 8.5. No EXAFS was measured in the system U(VI)-HA-kaolinite, therefore we performed also EXAFS measurements under different experimental conditions with U(VI)-HA-kaolinite sorbates in order to improve the knowledge about the surface complexes of U(VI). Results of the spectroscopic measurements are interpreted and compared with the results in the binary system without HA [1] to study the influence of HA on the near-neighbor surrounding of U(VI) in the kaolinite surface complexes. Obtained results help to improve the understanding of the geochemical interactions of hexavalent actinides in environment.

<dc:description><![CDATA[In burning stellar environments like supernova explosions, the temperatures are high enough for the production of heavy neutron deficient nuclei, the so-called p-nuclei. These are thought to be produced in such explosive scenarios either through chains of photodisintegration reactions on heavy seed nuclei. The modelling of the nucleosynthesis for the p-nuclei is mainly based on statistical model calculations. In this context, the knowledge of the experimental cross sections for the prediction of the p-nuclei abundances is of crucial importance and to forward in this direction we have started and experimental program at the bremsstrahlung facility of the superconducting electron accelerator ELBE of FZ Dresden-Rossendorf . Photodisintegration measurements on the astrophysically relevant p-nuclei 92Mo and 144Sm have been performed via photoactivation technique with bremsstrahlung end-point energies from 10.0 to 16.5 MeV. In particular the (gamma,alpha) reactions of the mentioned nuclei were studied for the first time at different endpoint energies above and close to the threshold. The bremsstrahlung facility and the experimental area are deigned so as to facilitate the studies under optimized background conditions. To probe the fascinating investigations on short-lived nuclei a new pneumatic delivery system has been built recently. First experiments on the short-lived decays following the reaction 144Sm(gamma,n) is discussed. The activation yields from all measurements are compared with calculations using cross sections from recent Hauser-Feshbach models .]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[Neutron irradiated reactor pressure vessel steel of two different Cu contents exposed to isochronal post-irradiation annealing treatments at stepwise increasing levels of temperature have been investigated. Results of small-angle neutron scattering experiments are reported and compared with the respective unirradiated and as-irradiated conditions. Volume distributions of scatterers and ratios of total to nuclear scattering intensities (A-ratio) were calculated from the measured differential macroscopic scattering cross sections. Finally, total volume fractions of scatterers, peak radii of the volume distribution and partial information on the composition of scatterers were extracted and discussed as a function of annealing temperature. Our measurements indicate that there is a temperature regime characterized by essentially complete dissolution of the irradiation-induced Cu-enriched clusters and another temperature regime characterized by a competition of dissolution and coarsening. An Arrhenius type of behaviour and a remarkable reversibility of the irradiation-induced cluster distribution are observed in the complete dissolution regime.]]></dc:description>

<dc:source><![CDATA[Physical Review B 73(2006), 125427]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The atomic arrangement in sp2-dominated carbon (C) and carbon nitride (CNx) thin films has been studied by Raman spectroscopy as a function of substrate temperature and, in the case of CNx, different N incorporation routes (growth methods). In this way, materials composing graphitelike, fullerenelike (FL), and paracyanogenlike structures have been compared. The results show that each type of arrangement results in a characteristic set of the Raman spectra parameters, which describe the degree of aromatic clustering, bond length, and angle distortion and order in sixfold structures. In the case of C films, the atomic structure evolves with substrate temperature from a disordered network to nanocrystalline planar graphitic configurations, with a progressive promotion in size and ordering of sixfold ring clusters. Nitrogen incorporation favors the promotion of sixfold rings in highly disordered networks produced at low temperatures, but precludes the formation of extended graphiticlike clusters at elevated substrate temperatures (>700 K). In the latter case, N introduces a high degree of disorder in sixfold ring clusters and enhances the formation of a FL microstructure. The formation and growth of aromatic clusters are discussed in terms of substrate temperature, N incorporation, growth rate, film-forming sources, and concurrent bombardment by hyperthermal particles during growth.]]></dc:description>

<dc:source><![CDATA[Instituts-Kolloqium, 25.10.2005, Wien, Österreich]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In the series of self-organized processes for the fabrication of nanostructures the pattern forma-tion during ion erosion of surfaces has attracted much interest in the last years. In the continuous sputtering process, induced by the bombardment with low-energy ions, periodic surface patterns appear in form of ripples under off-normal incidence or arrays of hexagonally ordered dots at normal incidence. The dimension of the pattern is related to the size of the typical collision cas-cade and lies in the range of ten to tens of nanometers, depending on ion energy. The self-organization mechanism relies on the interplay between a surface instability caused by the sput-tering, and surface diffusion processes. Regular ripple and dot array morphologies have been produced in this way on very different materials including semiconductors, insulators, and met-als, demonstrating the universality of the mechanism.]]></dc:description>

<dc:source><![CDATA[Physical Review Letters 95(2005), 257401]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[It is shown that the 2pz confined impurity state of a semiconductor quantum well develops into an excited impurity band in the case of a superlattice. This is studied by following theoretically the transition from a single to a multiple quantum well or superlattice by exactly diagonalizing the three dimensional Hamiltonian for a quantum well system with random impurities. Intersubband
absorption experiments, which can be nearly perfectly reproduced by the theory, corroborate this interpretation, which also requires re-interpretation of previous data.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[We propose a method for deterministic implantation of single atoms into solids which relies on a linear ion trap as an ion source. Our approach allows a deterministic control of the number of implanted atoms and a spatial resolution of less than 1 nm. Furthermore, the method is expected to work for almost all chemical elements. The deterministic implantation of single phosphor or nitrogen atoms is interesting for the fabrication of scalable solid state quantum computers, in particular for silicon and diamond based schemes. A wide range of further applications is expected for the fabrication of nano and sub-nano electronic devices.]]></dc:description>

<dc:description><![CDATA[Metal-oxide-silicon (MOS) structures containing different rare earth and germanium ions exhibit strong luminescence from 300 to 1540 nm.
It is very interesting from the viewpoint of the formation of silicon-based light-emitting devices. The different behaviour of charge trapping in Ge, Tb, Gd and Eu enriched SiO2 layer was studied under constant current regime. High-frequency (100 kHz) capacitors-voltage (C-V) characteristics exhibit a strong dependence of the charge trapping on the type of elements implanted into the SiO2 layer. The increase of the Eu concentration up to 3 percent leads to a shift of the C-V characteristics towards negative voltage in comparison with fresh samples, which reveals positive charge trapping. The capture cross section and the concentration of the different type of charge traps can also be strongly influenced by changing the annealing temperature and annealing time.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[The substrate/interface morphology and roughness plays a crucial role for the determination of the magnetic properties of ultrathin films. An anisotropic roughness can easily create magnetic anisotropy contributions of the same symmetry. It will be demonstrated that ion erosion fabricated ripples can be used to tailor the magnetic anisotropy and lead to a dramatic enhancement of the uniaxial magnetic anisotropy of Permalloy by a factor of up to 20. 
By means of 500 eV Ar+ ion erosion a rippled Si surface with a well defined periodicity (20  60 nm) and peak to valley height (2  5 nm) is created. The surface topography is investigated by means of atomic force microscopy. On top of this naturally oxidized surface, first a metallic buffer layer and then a 9 nm thin Permalloy layer is deposited by means of thermal evaporation. Depending on the buffer layer material (Cr, Mn, Pt, Cu) and thickness (0  20 nm) the ripple morphology is reproduced to a variable extent by the Permalloy film. The magnetization reversal behavior and the ripple-induced magnetic anisotropies are investigated by means of magneto-optic Kerr effect measurements and correlated to the interface morphology. An easy route for the tailoring of magnetic anisotropies is shown.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[Local void fractions measurements in two-phase flow phenomena are commonly carried out by the use of needle probes. The measuring principle of these probes is based on conductivity or optical measurements. In the past advanced needle probes with integrated micro-thermocouples have been introduced by Prasser et al., making possible to measure local temperatures at the same position where the void fractions are determined because the sheath of the micro-thermocouple serves as the measuring electrode for the conductivity measurement. Thereby - in principle - the temperatures of the two different phases (e. g. steam and water) can be distinguished. The big disadvantage of this technique is the relative long time constant (~20 ms) of mineral-insulated sheathed thermocouples. The usage of this type of thermocouples was necessary because the electronic was not able to separate the two signals (temperature and conductivity) from each other. Measuring of high-transient two phase flows were impossible due to the slow time response. Additionally the two signals had to be sampled sequentially because of influence of the rectangular excitation signal into the small temperature voltage. Investigations of temperature changing in the interfacial area between gas and liquid were therefore very difficult. To solve this problem we have developed a new combined temperature and conductivity needle probe measuring system, which is able to handle grounded or direct sheathed thermocouples (where the thermocouple wires are electrically-joined to the protective sheath) as well as open thermocouples (exposed junction).]]></dc:description>

<dc:title><![CDATA[Enhanced local void and temperature measurements for high-transient two-phase flows]]></dc:title>
<dc:source><![CDATA[IEEE Instrumentation and Measurement Technology Conference, 24.-27.04.2006, Sorrento, Italy]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Local void fractions measurements in two-phase flow phenomena are commonly carried out by the use of needle probes. The measuring principle of these probes is based on conductivity or optical measurements. In the past advanced needle probes with integrated micro-thermocouples have been introduced by Prasser et al., making possible to measure local temperatures at the same position where the void fractions are determined because the sheath of the micro-thermocouple serves as the measuring electrode for the conductivity measurement. Thereby - in principle - the temperatures of the two different phases (e. g. steam and water) can be distinguished. The big disadvantage of this technique is the relative long time constant (~20 ms) of mineral-insulated sheathed thermocouples. The usage of this type of thermocouples was necessary because the electronic was not able to separate the two signals (temperature and conductivity) from each other. Measuring of high-transient two phase flows were impossible due to the slow time response. Additionally the two signals had to be sampled sequentially because of influence of the rectangular excitation signal into the small temperature voltage. Investigations of temperature changing in the interfacial area between gas and liquid were therefore very difficult. To solve this problem we have developed a new combined temperature and conductivity needle probe measuring system, which is able to handle grounded or direct sheathed thermocouples (where the thermocouple wires are electrically-joined to the protective sheath) as well as open thermocouples (exposed junction).]]></dc:description>

<dc:title><![CDATA[Gerichtete Erstarrung von Pb-Sn-Legierungen unter Einwirkung eines rotierenden Magnetfeldes]]></dc:title>
<dc:source><![CDATA[International Foundry Research 58(2006)2, 38-46]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Bereits seit einiger Zeit ist bekannt, dass man durch gezieltes Rühren einer erstarrenden, metallischen Schmelze mit mechanischem Antrieb oder mit Hilfe zeitabhängiger Magnetfelder in aktiver Weise Einfluss auf die Gefügeausbildung nehmen kann. Diese sogenannte, erzwungene Konvektion begünstigt beispielsweise globulitisches gegenüber dendritischem Wachstum und bewirkt eine Kornfeinung. Allerdings können Strömungen im Schmelzbad während der Erstarrung auch unerwünschte Makroseigerungen hervorrufen. 
Der Einsatz elektromagnetischer Felder zum Rühren des Schmelzbades ist vor allen Dingen aus zweierlei Gründen attraktiv: (a) diese Methode bietet die Möglichkeit einer völlig kontaktlosen Einflussnahme und (b) eine unmittelbare und einfache Kontrolle der Intensität der Strömung kann über die elektrischen Regelparameter Strom und Frequenz vorgenommen werden. Zusätzlich sind verschiedene Arten von Magnetfeldern (Wanderfelder, pulsierende Felder, statische Felder) im Prinzip beliebig kombinierbar. Damit ergibt sich die Möglichkeit, grundsätzlich verschiedene Strömungsmuster je nach Bedarf zu erzeugen.   
Das Ziel unserer Forschung besteht in der Anwendung maßgeschneiderter Magnetfelder während der Erstarrung zur effizienten Herstellung homogener, feinkörniger, globulitischer Gefüge. Zunächst soll mit Hilfe von Modellexperimenten, die die Komplexität des Problems überschaubar halten, mehr Informationen über die physikalischen Zusammenhänge zwischen der Erstarrung metallischer Legierungen und einer erzwungenen Konvektion in der Restschmelze gesammelt werden. Dazu wurden Pb-Sn-Legierungen in einer einfachen zylindrischen Geometrie unter Einwirkung eines rotierenden Magnetfeldes (RMF) gerichtet erstarrt.]]></dc:description>

<dc:description><![CDATA[Research at extreme material conditions can lead to new scientific knowledge. As an example, experiments at low temperatures and high magnetic fields have improved the understanding of matter dramatically in the last century. Nowadays, we dispose of the technology to reach ultralow temperatures, highest magnetic fields and even to produce material structures on length scales on which the geometrical size dominates physical properties. In this talk, research examples on superconducting nanogranular metals, quantum functional intermetallic compounds, nuclear magnetic superconductors, as well as magnetic high temperature superconductors will be presented. In addition, magnetic cooling technology and the non-destructive generation of highest pulsed magnetic fields will be briefly introduced along with facilities, e.g. the new Dresden High Magnetic Field Laboratory (HLD)*.

*HLD is a new large scale facility for the generation of pulsed magnetic fields up to 100 T which is under construction during 2003 to 2006 and which will open its doors for users in early 2007.]]></dc:description>

<dc:description><![CDATA[Most of the proposed electron accelerator projects for FELs, ERLs, or 4th generation light sources require electron beams with an unprecedented combination of high-brightness, low emittance and high average current. In all of the projects photo guns will be applied: DC-photoguns, normal conducting RF photoguns (NC-guns), and superconducting RF photoguns (SRF-guns). While the concepts of DC- and NC-guns are well proofed, the SRF gun development still possesses a high risk. Challenges are the thermal and contaminant isolation needed between the cathode and superconducting cavity, the choice of the right photocathode and its life time, the difficulty of coupling high-average power into the gun, and beam excitation of higher order cavity modes.      But in combination with  SRF-linacs, the SRF-guns are best solution for high current and CW operation is simply possible. Thus, several R&D projects of SRF-gun have been launched. The talk will give an overview of the history and progress of the SRF-gun development. In detail the technical concept, performance, and status of the Rossendorf superconducting rf gun project, a collaboration of BESSY, DESY, MBI and FZR, will be presented. ]]></dc:description>

<dc:title><![CDATA[The feasibility of in-beam PET for therapeutic beams of 3 He]]></dc:title>
<dc:source><![CDATA[PTCOG 43, 10.-14.12.2005, München, Deutschland]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[At present in-beam PET is the only possibility for an in-situ monitoring of the particle delivery in hadron tumor therapy and there is a unique clinical implementation at the Gesellschaft fuer Schwerionenforschung (GSI) Darmstadt.
Several heavy ion treatment facilities are under construction, which will provide a large variety of ions from protons to oxygen. This requires a precise knowledge of the spatial distribution of beam induced positron emitters in the irradiated volume. For the 3He-case experiments at GSI with three mono-energetic 3He-beams of  130.03 AMeV to 207.92 AMeV  have been carried out. The beams were stopped in homogeneous thick targets consisting of  PMMA, graphite and water. Results on the production rate and the spatial distribution of 3He ion induced  beta+-activity will be presented and compared with data from 12C-irradiation. From these, the accuracy and resolution for determining the range of the 3He primary beams is deduced. Furthermore, energy dependent thick target cross sections for different reaction channels leading to positron emitters will be estimated from the experimental data.]]></dc:description>

<dc:description><![CDATA[Die Rossendorfer Zweiquellenionenstrahlanlage stellt eine weltweit einmalige Kombination aus einer Elektron-Zyklotron-Resonanz-Ionenquelle mit einer bei Raumtemperatur arbeitenden Elektronenstrahl-Ionenquelle, der Dresden EBIT, dar. Die Ionenstrahlen beider Quellen münden in eine gemeinsame Targetkammer und stehen dort für Experimente zur Verfügung. Die erreichbaren Ladungszustände, die Ionenströme sowie die Energien der Ionen aus beiden Quellen unterscheiden sich aufgrund der verschiedenen Wirkungsprinzipien und gewährleisten so ein breites Spektrum an Experimenten. Die Gesamtanlage kann gegenüber der Targetkammer auf  ein negatives Potential gebracht werden, wodurch sich die Ionen beider Quellen bis auf Energien unter q*100V abbremsen lassen. Die Untersuchung der Wechselwirkung langsamer hochgeladener Ionen mit Festkörperoberflächen, insbesondere der Einfluss der Potentialenergie der Ionen, ist neben der Ionenquellendiagnostik Gegenstand aktueller Forschungen an der Rossendorfer Zweiquellenanlage.]]></dc:description>

<dc:description><![CDATA[Es wurde ein Modell zur realistischen Beschreibung der Kühlmittelvermischung innerhalb des Reaktordruckbehälters von Druckwasserreaktoren in den gekoppelten Programmkomplex DYN3D/ATHLET implementiert. Diese Modell basiert auf dem Prinzip der linearen Superposition Dirac-Impuls-ähnlicher Störungen und kann für die Modellierung der Vermischung von Kühlmittel unterschiedlicher Temperatur und/oder unterschiedlicher Borsäurekonzentration eingesetzt werden. Der um das Vermischungsmodell erweiterte Programmkomplex DYN3D/ATHLET wurde für Analyse von Borverdünnungsstörfällen und Frischdampflecks angewandt. Für den Fall Start der ersten Hauptkühlmittelpumpe bei Vorhandensein eines minderborierten Pfropfens im kalten Strang zeigten die Ergebnisse der durchgeführten Parame-terstudie, dass es selbst bei Annahme des maximal möglichen Pfropfenvolumens nicht zu einer Schädigung des Brennstoffes kommt. Mit den Analysen zu einem generischen Frischdampfleckszenario wurde die Anwendbarkeit des Programmkomplexes DYN3D/ATHLET auf die zweite Störfallklasse, in der die Kühlmittelvermischung eine wichtige Rollen spielt, demonstriert.
Im Rahmen der Arbeiten zum Projekt wurde außerdem gezeigt, dass der Einfluss der turbulenten Schwankungen des Geschwindigkeitsfeldes innerhalb des Reaktordruckbehälters auf neutronenkinetische Parameter im Nominalbetrieb und unter Störfallbedingungen nicht zu vernachlässigen ist. 

A model for the realistic description of the coolant mixing inside the pressure vessel of pressurized water reactors was implemented into the coupled code complex DYN3D/ATHLET. This model is based on the linear superposition Dirac-pulse-like perturbations. The model can be applied to the mixing of coolant of different temperature and/or boron concentration. The coupled code complex DYN3D/ATHLET with the newly implemented model was applied to the analysis of boron dilution and steam line break accidents. The results of a parameter study for the case Start-up of the first main coolant pump with a slug of lower borated water in the cold leg have shown, that even under the conditions of the maximum slug volume there is no fuel damage. The applicability to the second class of accidents, where the coolant mixing has to be considered, was demonstrated by the analysis of a generic main steam line break scenario. 
Further it was shown, that the influence of turbulent fluctuations of the velocity inside the reactor pressure vessel during nominal and accident conditions on neutron-kinetic parameters cannot be neglected.]]></dc:description>

<dc:description><![CDATA[The important element of modern Al<SUB>x</SUB>Ga<SUB>1-x</SUB>As semiconductor lasers is an insulating buried layer introduced by selective implantation with He or H ions. The difficulty in obtaining of such layers is connected with controlling of strain and defects introduced by implantation, which may disturb the action of the laser. The strain may be however controlled in less complicated laterally homogeneous structures or even single implanted layer.
The insulated buried layers obtained by implantation of 150 keV He ions to Al<SUB>x</SUB>Ga<SUB>1-x</SUB>As with various concentration of Al and GaAs were studies with different synchrotron diffraction methods exploring both white and monochromatic beam.The selected samples were studied with high resolution transmission electron microscopy. The implantation were performed at room temperature, 80°C and 120°C. The doses were in the range from 2x10<SUP>16</SUP> to 6x10<SUP>16</SUP> cm<SUP>-2</SUP>. The synchrotron experiment included taking local rocking curves using small 50x50 µm<SUP>2</SUP> probe beam. The rocking curves exhibit characteristic sequence of interference maxima and enabled the analysis of the strain profiles by fitting the theoretical rocking curves obtained by numerical integration of the Takagi-Taupin equations. The white beam synchrotron back reflection topography revealed a sequence of strain modulation fringes similar to the main interference maxima in the rocking curves. They also confirm the uniformity of applied dose and lack of extended crystallographic defects which could be caused by implantation. The characteristic feature of the evaluated profiles was the existence of the deformed region close to the surface which points that the deformation is mainly caused by point defects produced by incident ions and recoils. The other feature increasing with the temperature of implantation was the flattening of top part of the strain maximum corresponding to the insulating buried layer.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Ge nanocluster formation in SiO2 is of growing interest for new electronic applications. Ion beam synthesis using high-energy Ge implantation connected with thermal annealing is one possible preparation method of such clusters. In addition to investigations of electrical and structural changes during the cluster formation process we also studied chemical changes in the samples using x-ray photoelectron spectroscopy (XPS). This was done with low-energy noble gas ion sputtering for depth profiling. Binding state information one can get from the XPS data by means of factor analysis (FA) in combination with other structural investigations.
However, mixed bonding states probably created by ion beam damage during sputter erosion are dominating the results. It is shown, that by changing the experimental conditions (ion beam impact depth during sputtering, electron information depth during XPS measurement) these mixed states are influenced in an appropriate manner. It is concluded that useful chemical information on the behavior of the implanted Ge can be derived despite of the ion beam damage.]]></dc:description>

<dc:description><![CDATA[The <SUP>11</SUP>C-labelling of the taxane derivative BAY 59-8862 (1), a potent anticancer drug, was carried out as a module-assisted automated multi-step synthesis procedure. The radiotracer [<SUP>11</SUP>C]1 was synthesized by reacting [1-<SUP>11</SUP>C]acetyl chloride (6) with the lithum salt of the secondary hydroxy group of precursor 3 followed by deprotection. After HPLC purification of the final product [<SUP>11</SUP>C]1, its solid phase extraction, formulation and sterile filtration, the decay-corrected radiochemical yield of [<SUP>11</SUP>C]1 was in the range between 12 and 23% (related to [<SUP>11</SUP>C]CO<SUB>2</SUB>; n = 10). The total synthesis time was about 54 min after EOB. The radiochemical purity of [<SUP>11</SUP>C]1 was greater than 96% and the chemical purity exceeded 80%. The specific radioactivity was up to 20 GBq/µmol at EOS starting from 80 GBq of [<SUP>11</SUP>C]CO<SUB>2</SUB>.]]></dc:description>

<dc:description><![CDATA[Die Leistungsfähigkeit der Nuklearmedizin in der Diagnostik, Therapie und medizinischen Forschung hängt entscheidend vom Fortschritt bei der Entwicklung neuer geeigneter Radiopharmaka ab. Die Auswahl, die Herstellung und die präklinische Evaluation dieser neuen Radiopharmaka ist Gegenstand der radiopharmazeutischen Chemie. Vor dem Hintergrund der rasanten Entwicklungen auf den Gebieten der Biowissenschaften im Post-Genom Zeitalter und der technologischen Fortschritte bei der Instrumentierung der bildgebenden nuklearmedizinischen Verfahren SPECT und PET hat sich die Radiopharmakaforschung in den letzten Jahren zu einer komplexen chemischen Wissenschaft entwickelt. Die Schwerpunkte der aktuellen Radiopharmakaforschung umfassen dabei besonders neue koordinationschemische Entwicklungen auf dem Gebiet der [<SUP>99m</SUP>Tc]Technetium Radiopharmaka, die Herstellung von sogenannten Nicht-Standard Radionukliden für die PET sowie die Synthese von <SUP>11</SUP>C- und <SUP>18</SUP>F-markierten Radiopharmaka mit hoher spezifischer Radioaktivität. 
Weitere wichtige Entwicklungen zeichnen sich durch die zunehmende Ausrichtung der Radiopharmakaforschung auf die Entwicklung von Radiotherapeutika und die Einbeziehung der PET in die Arzneimittelentwicklung und -evaluation ab.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[A method has been developed for determination of In concentration in strained layers of InGaAs/GaAs heterostructures. Chemical composition and lattice strain were evaluated from the reciprocal space maps obtained for asymmetric reflections. It was observed that beginning of
relaxation of the In0.13Ga0.87As/GaAs (0 0 1) system with lattice misfit Delta-a/a = 9.3×10−3 and the critical thickness tc(MB) = 15 nm can be detected for layers of thickness exceeding t∼
70 nm ∼ 4.5tc(MB). The principal relaxation mechanism is due to the slipping of 60° misfit dislocations on the tilted (1 1 1) glide planes. The accuracy of indium concentration measurements was estimated to Delta-x =±0.01.]]></dc:description>

<dc:source><![CDATA[Joint Meeting of the German Vacuum Society (DVG) and the Polish Vacuum Society (PTP), 26.-29.10.2005, Krakow, Polen]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[There is a high demand of lateral structures with dimensions from some nanometers to tens of nanometers in the fields of electronics, magnetic storage, and biology. This has triggered research activities in self-organization and self-assembling mechanisms for their fabrication which can successfully complement the classical methods of lithography. These self-organization processes, classified as bottom-up approaches, in contrast to the top-down approaches of lithography, will join more and more the nanotechnology. 
In the series of self-organized processes for the fabrication of nanostructures the pattern formation during ion erosion of surfaces has attracted much interest in the last years. In the continuous sput-tering process, induced by the bombardment with low-energy ions, periodic surface patterns ap-pear in form of ripples under off-normal incidence or regular arrays of hexagonally ordered dots at normal incidence. The dimension of the patterns is related to the size of the typical collision cascade and lies in the range of ten to tens of nanometers, depending primary on ion energy, inci-dence angle, and surface temperature. The self-organization mechanism relies on the interplay between a surface instability caused by the sputtering and surface diffusion processes. Regular ripple and dot morphologies have been produced in this way on very different materials including semiconductors, and metals, demonstrating the universality of this mechanism.]]></dc:description>

<dc:description><![CDATA[The role of the lift force for the stability of a homogeneous bubble column is investigated. Instabilities caused by the lift force may be one important reason for the transition from homogeneous to heterogeneous bubble column. The lift force acts on rising bubbles in lateral direction, when gradients of the liquid velocity are present. Non-uniform liquid velocity fields may be induced if the gas fraction is not equally distributed, e.g. caused by local disturbances. For regions with locally increased gas volume fraction the liquid is accelerated in upwards direction and following a gradient of the liquid velocity occurs. This causes a lateral redistribution of the gas bubbles. Depending on the sign of the lift force coefficient this can act to smooth the spatial bubble distribution (positive lift force coefficient) or to increase the initial disturbances (negative lift force coefficient). The feedback mechanism was studied by the means of a linear stability analysis. In addition to the lift force, the turbulent dispersion force is considered, which has always a stabilizing effect, i.e. it partially compensates the destabilisation induced by a negative lift coefficient. The stability analysis for a mono-dispersed system nevertheless showed, that influence of the lift force is much larger, compared to the influence of the turbulent dispersion force, if only bubble induced turbulence is considered. Thus the stability condition is practically the positive sign of the lift force coefficient. The analysis was then extended to two bubbles classes - one being small enough to have a positive lift force coefficient, the other being large enough to have a negative coefficient. The result of the analysis is a condition for the minimum fraction of small bubbles needed for stability. Finally a generalized criterion for N bubble classes and for a continuous bubble size distribution is given. Recently two different groups confirmed the stability criteria experimentally.]]></dc:description>

<dc:description><![CDATA[It was shown recently that a simple  mean-field dynamo model with a spherically symmetric helical turbulence parameter alpha can show a number of features of Earth's magnetic field reversals. This model relies basically on the existence of an exceptional point of the spectrum of the non-selfadjoint dynamo operator. It is shown that highly supercritical dynamos undergo a self-tuning process into a reversal prone state. As a consequence, reversing dynamos might be much more typical and may occur much more frequently in nature than what could be expected from a purely kinematic perspective.]]></dc:description>

<dc:source><![CDATA[International Journal of Pressure Vessels and Piping 83(2006), IPVP2676]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The Master Curve (MC) approach used to measure the transition temperature, T0, has been standardized in the ASTM Standard Test Method E 1921 in 1997. The basic MC approach for analysis of fracture test results is intended for macroscopically homogeneous steels with a body centered (ferritic) structure only. In reality, due to the manufacturing process, the steels in question are seldom fully macroscopically homogeneous.
The fracture toughness values measured on Charpy size SE(B) specimens of base metal from the Greifswald Unit 8 RPV show a large scatter. The basic MC evaluation following ASTM E1921 supplies a MC with many fracture toughness values which lie below the 1% fracture probability line. It is therefore suspected that this material is macroscopically inhomogeneous. In this paper, two recent extensions of the MC for inhomogeneous material are applied on these fracture toughness data.]]></dc:description>

<dc:description><![CDATA[Sample analysis of seepage waters from old uranium mill tailings in Saxony and Thuringia shows both phosphate and uranium contents up to 10(-5) molar. Therefore the impact of phosphate on the speciation and transport behavior of uranium has to be investigated. At present, available complexation data are based only on few experiments and are not fully consistent. Therefore, the complex stability constants of the various uranyl(if) phosphate complexes were determined Over a pH range from 2 to 5 for uranyl and phosphate concentrations to 10(-6) molar, using potentiometric titrations and time-resolved laser-induced fluorescence spectroscopy (TRLFS). Fluorescence lifetimes were obtained for the free uranyl cation and uranyl phosphate complexes. Stability constants were determined for the complexes UO2(H2PO4)(2)(aq), UO2(H2PO4)(+) and UO2HPO4(aq), using the software C-LETAGROP [1] and SQUAD [2]. The results are compared with the values recommended by NEA [3] and with some recent publications.]]></dc:description>

<dc:title><![CDATA[Quantifizierung des Uptake von Rhenium-188-HEDP im trabekuären und kortikalen Knochen sowie in Knochenmetastasen im Tierversuch]]></dc:title>
<dc:source><![CDATA[Nuklearmedizin 45(2006)2, A112]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Ziel/Aim:
Die MIRDDOSE Annahme einer 50% zu 50% Verteilung knochenaffiner Radiopharmaka im kortikalen und der trabekulären Knochen sowie einer homogene Anreicherung in den Knochenmetastasen dürfte nicht den reellen Verhältnissen entsprechen.

Methodik/Methods:
Ein Modell zur Induktion von osteoblastischen Knochenmetastasen wurde durch intra-ossäre Injektion von Prostata-Karzinomzellen bei Kopenhagenratten in einer Vorversuchsserie entwickelt. In histologischen Untersuchungen konnte das Vorliegen von osteoblastischen Knochenmetastasen bewiesen und diese szintigraphisch dargestellt werden.

Bei 45 Kopenhagenratten (Alter: 9 ± 2 Monate, Gewicht: 318 ± 22g) wurden jeweils 100.000 R3327 Mat-Ly-Tu Zellen in beide Femura injiziert. Ab dem 12. Tag nach Zellapplikation war makroskopisch ein Tumor gut sichtbar. 17 ± 1 Tage nach Tumorzellapplikation erfolgte die Applikation von 134 ± 53 MBq Re-188-HEDP sowie nachfolgend die Tötung von jeweils 15 Tiere 4, 24 und 48 Stunden. Coronare Gefrierschnitte (Cryopolycut, Leica, 40 #mikro#m dick) wurden autoradiographisch mit einer Auflösung von 0,5 #mikro#m (BAS 500, Fuji) untersucht. Mittels ROI-Technik erfolgte die Bestimmung der Anreicherung des Re-188-HEDP pro mm3. Nachfolgend wurden die Verhältnisse zwischen Tumor und normaler Knochen (T/NT) berechnet, sowie die Verteilung im kortikalen und der trabekulären Knochen quantifiziert.

Ergebnisse/Results:
Es zeigte sich eine Verteilung im kortikalen und der trabekulären Knochen von 33,5% zu 66,5% nach 4h, von 34,6% zu 65,4% nach 24h und von 35,9% zu 64,1% nach 48h (p = 0,788 bis 0,871). In den Knochenmetastasen zeigte sich eine stark inhomogene Anreicherung mit einer minimalen und maximalen T/NT von 3:1 und 14:1 nach 4h, von 5:1 und 14:1 nach 24h sowie von 5:1 und 16:1 nach 48h, der Anstieg über die Zeit ist nicht signifikant. Die maximale Anreicherung in einer Metastase betrug 22:1. Bei erneuter Berechnung der Knochenmarkdosis aus vorliegender Daten einer Rhenium-188-HEDP Therapie beim Menschen, ergab sich bei einer Zugrundelegung einer Verteilung von 35% zu 65% (kortikal zu trabekulär) eine um 135% höhere Dosis als bei einer Verteilung von 50% zu 50%.

Schlussfolgerungen/Conclusions:
Das MIRDOSE Schema unterschätzt die reelle Dosis im Knochenmark. Die stark inhomogene Anreicherung in den Knochenmetastasen führt zu einer inhomogenen Dosisverteilung in den Metastasen, bei Anwendung von Betastrahlern mit einer höheren Beta-Energie lässt sich eine homogenere Dosisverteilung erreichen.]]></dc:description>

Bei 45 Kopenhagenratten (Alter: 9 ± 2 Monate, Gewicht: 318 ± 22g) wurden jeweils 100.000 R3327 Mat-Ly-Tu Zellen in beide Femura injiziert. Ab dem 12. Tag nach Zellapplikation war makroskopisch ein Tumor gut sichtbar. 17 ± 1 Tage nach Tumorzellapplikation erfolgte die Applikation von 134 ± 53 MBq Re-188-HEDP sowie nachfolgend die Tötung von jeweils 15 Tiere 4, 24 und 48 Stunden. Coronare Gefrierschnitte (Cryopolycut, Leica, 40 #mikro#m dick) wurden autoradiographisch mit einer Auflösung von 0,5 #mikro#m (BAS 500, Fuji) untersucht. Mittels ROI-Technik erfolgte die Bestimmung der Anreicherung des Re-188-HEDP pro mm3. Nachfolgend wurden die Verhältnisse zwischen Tumor und normaler Knochen (T/NT) berechnet, sowie die Verteilung im kortikalen und der trabekulären Knochen quantifiziert.

Ergebnisse/Results:
Es zeigte sich eine Verteilung im kortikalen und der trabekulären Knochen von 33,5% zu 66,5% nach 4h, von 34,6% zu 65,4% nach 24h und von 35,9% zu 64,1% nach 48h (p = 0,788 bis 0,871). In den Knochenmetastasen zeigte sich eine stark inhomogene Anreicherung mit einer minimalen und maximalen T/NT von 3:1 und 14:1 nach 4h, von 5:1 und 14:1 nach 24h sowie von 5:1 und 16:1 nach 48h, der Anstieg über die Zeit ist nicht signifikant. Die maximale Anreicherung in einer Metastase betrug 22:1. Bei erneuter Berechnung der Knochenmarkdosis aus vorliegender Daten einer Rhenium-188-HEDP Therapie beim Menschen, ergab sich bei einer Zugrundelegung einer Verteilung von 35% zu 65% (kortikal zu trabekulär) eine um 135% höhere Dosis als bei einer Verteilung von 50% zu 50%.

Schlussfolgerungen/Conclusions:
Das MIRDOSE Schema unterschätzt die reelle Dosis im Knochenmark. Die stark inhomogene Anreicherung in den Knochenmetastasen führt zu einer inhomogenen Dosisverteilung in den Metastasen, bei Anwendung von Betastrahlern mit einer höheren Beta-Energie lässt sich eine homogenere Dosisverteilung erreichen.]]></dc:description>

<dc:title><![CDATA[Speciation of uranium in seepage waters from a mine tailing pile studied by time-resolved laser-induced fluorescence spectroscopy (TRLFS)]]></dc:title>
<dc:source><![CDATA[Radiochimica Acta 74(1996), 87-91]]></dc:source>
<dc:date>1996</dc:date>
<dc:description><![CDATA[Chemical speciation of U(VI) in natural seepage water and corresponding model solutions was investigated by time-resolved laser-induced fluorescence spectroscopy. Calculations of uranium speciation in this medium show that UO2(CO3)(3)(4-) and UO2(CO3)(2)(2-) should be the major individual components. Due to the very low fluorescence intensity, the pure uranyl carbonate complexes could not be measured directly by TRLFS. However, a uranium fluorescence spectrum was recorded from seepage water samples. The TRLFS investigations show that the main component of uranium in this seepage water is a calcium uranium carbonate complex. The main fluorescence wavelengths of this complex are at 463.9, 483.6, 502.8, 524.3 and 555.4 nm. The fluorescence lifetime of the species is 64+/-17 ns. This study shows that the calcium content of the water has a great influence on the uranium speciation. For the first time, the existence of a calcium uranium carbonate complex - {Ca-2[UO2(CO3)3]}((ag.)) - is reported. The stability constant was determined to be log beta = 26.8+/-0.7. Existing thermodynamic data bases do not contain this species and modeling calculation must lead to erroneous results in the medium under investigation.]]></dc:description>

<dc:description><![CDATA[Dynamics of the Molten Salt Reactor, one of the 'Generation IV International Forum' concepts, was studied in this paper. The graphite-moderated channel type MSR was selected for the numerical simulation. The MSR represents a liquid fueled reactor and its dynamics is very specific because of two physical peculiarities: the delayed neutrons precursors are drifted by the fuel flow and the fission energy is immediately released directly into the coolant. Presently, there are not many accessible numerical codes appropriate for the MSR simulation, therefore the DYN3D-MSR code was developed based on the Light Water Reactor dynamics code DYN3D. It allows calculating of full 3D transient neutronics in combination with parallel channel type thermal-hydraulics. The code was validated on experimental results of Molten Salt Reactor Experiment (from Oak Ridge National Laboratory) and applied to several transients typical for the liquid fuel system. Those transients were initiated by reactivity insertion, by overcooled or overfueled fuel slug, by the fuel pump start-up or coast-down, or by the blockage of single fuel channels. In these considered transients, the response of the MSR is characterized by the immediate change of the fuel temperature according to the power level. This causes fast feedback reactivity insertion, which is negative in the case of power increase. On the other hand, the graphite response is slower and its feedback coefficient is in some cases positive. The addition of erbium to the graphite can ensure the negative feedback and inherent safety features. The DYN3D-MSR code has been shown to be an effective tool for MSR dynamics studies.]]></dc:description>

<dc:source><![CDATA[The 11th International Topical Meeting on Nuclear Reactor Thermal-Hydraulics (NURETH-11), 02.-06.10.2005, Avignon, France]]></dc:source>

<dc:description><![CDATA[Wire-mesh sensors are used for a high-speed visualization of a gas-liquid flow as well as for the measurement of void fraction profiles, bubble size distributions and gas velocity distributions. Recent progress was made in designing and constructing such sensors for an application in a hot steam-water mixture. Two types are presented: (1) a sensor with an inner diameter of 52.3 mm with a measuring matrix of 16x16 and (2) a sensor of 195 mm inner diameter with 64x64 measuring points. Both devices can be operated at 7 MPa and a temperature of max. 286 °C. The spatial and temporal resolutions are equal to earlier used sensors for air-water flow at ambient conditions (3 mm, 2500 fps). In the paper, the function of the sensors is illustrated by presenting flow visualizations obtained at two vertical test sections of the Rossendorf TOPFLOW facility. The pipes are approximately 9 m long and have inner diameters equal to the diameters of the measuring cross sections mentioned above. The results show how the flow structure depends on the thermodynamic parameters by comparing measurements performed at 1, 2, 4 and 6.5 MPa and 180, 212, 250 and 280 °C, correspondingly, under adiabatic conditions with earlier air-water tests.]]></dc:description>

<dc:description><![CDATA[Wire-mesh sensors are used for a high-speed visualization of a gas-liquid flow as well as for the measurement of void fraction profiles, bubble size distributions and gas velocity distributions. Recent progress was made in designing and constructing such sensors for an application in a hot steam-water mixture. Two types are presented: (1) a sensor with an inner diameter of 52.3 mm with a measuring matrix of 16x16 and (2) a sensor of 195 mm inner diameter with 64x64 measuring points. Both devices can be operated at 7 MPa and a temperature of max. 286 °C. The spatial and temporal resolutions are equal to earlier used sensors for air-water flow at ambient conditions (3 mm, 2500 fps). In the paper, the function of the sensors is illustrated by presenting flow visualizations obtained at two vertical test sections of the Rossendorf TOPFLOW facility. The pipes are approximately 9 m long and have inner diameters equal to the diameters of the measuring cross sections mentioned above. The results show how the flow structure depends on the thermodynamic parameters by comparing measurements performed at 1, 2, 4 and 6.5 MPa and 180, 212, 250 and 280 °C, correspondingly, under adiabatic conditions with earlier air-water tests.]]></dc:description>

<dc:description><![CDATA[We investigated the uranium speciation in a former WISMUT mine tailing, which was buried for 30 years under mine and construction debris.
Chemical extractions, EXAFS,  -XRD, and  -XRF reveal two major U pools. The first with a relatively high potential mobility was identified as U(VI) sorbed to layer silicates by inner-sphere complexation; the second pool is represented by the relatively insoluble U(IV) minerals pitchblende and coffinite, and by the U(VI) solids uranyl hydroxide and vanuralite.
Distribution between the two pools seems to be con-trolled by pH. Evidence for reductive precipitation of uraninite was found.]]></dc:description>

<dc:description><![CDATA[The improbable scenario of a severe accident with core meltdown and formation of a melt pool in the lower plenum of a Light Water Reactor (LWR) Pressure Vessel (RPV) can result in the failure of the RPV and the discharging of the melt to the containment. One accident management strategy could be to stabilize the in-vessel debris or melt pool configuration in the RPV as one major barrier against uncontrolled release of heat and radionuclides into the containment of the plant.
Based on the successful simulation and analysis work of the FOREVER-experiments the models have been developed further to simulate the prototypical scenario of an In-Vessel-Retention in a large German PWR (KONVOI). As shown in an earlier publication a recursively coupled simulation between the thermal and the mechanical model has to be performed to consider the mutual influence of the heat fluxes respectively the temperatures and the mechanical vessel behaviour.
After the validation of the recursively coupled thermal and mechanical FE-models against the scaled FOREVER-tests the models were improved to simulate a prototypic scenario under certain assumptions. The calculations show that an In-Vessel-Retention might be possible for large PWRs like KONVOI, if the RPV is flooded externally. The remaining vessel wall thickness seems to be sufficient to prevail even higher pressure loads. But in any case a support of the lower head would increase the margin to failure and therefore ensure the integrity of the last barrier within the containment of the plant.]]></dc:description>

<dc:description><![CDATA[Coolant mixing in the cold leg, downcomer and the lower plenum of pressurized water reactors is an important phenomenon mitigating the reactivity insertion into the core. Therefore, mixing of the de-borated slugs with the ambient coolant in the reactor pressure vessel was investigated at the four loop 1:5 scaled ROCOM mixing test facility. Thermal hydraulics analyses showed, that weakly borated condensate can accumulate in particular in the pump loop seal of those loops, which do not receive safety injection. After refilling of the primary circuit, natural circulation in the stagnant loops can re-establish simultaneously and the de-borated slugs are shifted towards the reactor pressure vessel (RPV). In the ROCOM experiments, the length of the flow ramp and the initial density difference between the slugs and the ambient coolant was varied.

From the test matrix an experiment with 2% density difference between the de-borated slugs and the ambient coolant was used to validate the CFD software ANSYS CFX. To model the effects of turbulence on the mean flow a Reynolds stress turbulence model was employed and a hybrid mesh consisting of 3.6 million nodes and 6.4 million elements was used.

The experiment and CFD calculation show a stratification in the downcomer. The less dense slugs flow around the core barrel at the top of the downcomer. At the opposite side the lower borated coolant is entrained by the colder safety injection water and transported to the core.The validation proves that ANSYS CFX is able to simulate appropriately the flow field and mixing effects of coolant with different densities.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[Ion implantation of nitrogen into samples of tempered and quenched H13 steel was carried out by plasma immersion technique. A glow discharge plasma of nitrogen species was the ion source and the negative high voltage pulser provided 10-12 kV, 60 mu s duration and 1.0-2.0 kHz frequency, flat voltage pulses. The temperatures of the samples remained between 300 and 450 degrees C, sustained solely by the ion bombardment. In some of the discharges, we used a N-2 + H-2 gas mixture with 1:1 ratio. PIII treatments as long as 3, 6, 9 and up to 12 h were carried out to achieve as thickest treated layer as possible, and we were able to reach over 20 mu m treated layers, as a result of ion implantation and thermal (and possibly radiation enhanced) diffusion. The nitrogen depth profiles were obtained by GDOS (Glow Discharge Optical Spectroscopy) and the exact composition profiles by AES (Auger Electron Spectroscopy). The hardness of the treated surface was increased by more than 250%, re!  aching 18.8 GPa. No white layer was seen in this case. A hardness profile was obtained which corroborated a deep hardened layer, confirming the high efficacy of the moderate temperature PIII treatment of steels.]]></dc:description>

<dc:description><![CDATA[The application of nuclear analytical methods on surface and interface study is presented. Two topics are included in the presentation - polymer-metal interaction studies and study of single-crystalline structures using RBS-channeling method. Diffusion of Ag atoms in polyethyleneterephtalate (PET) was studied using Rutherford Backscattering Spectroscopy (RBS) and Elastic Recoil Detection Analysis (ERDA). The samples were prepared by deposition of Ag thin layers on polymer surface using CVD and diode sputtering techniques. Faster diffusion of Ag atoms was observed from non-compact Ag layers prepared by diode sputtering than from those prepared by CVD technique. The samples of erbium doped lithium niobate (Er:LiNbO3) were prepared by standard Czochralski method and treated by Annealed Proton Exchange (APE) procedure to create planar wave-guide for further optical application. The position of Er atoms in the crystal lattice of pristine and APE treated Er:LiNbO3 samples were studied by Rutherford Backscattering Spectrometry (RBS)-channeling method. The Er3+ ion position in the pristine and the APE treated Er:LiNbO3 samples are compared.]]></dc:description>

<dc:source><![CDATA[11th International Symposium on Microbial Ecology, ISME-11, 20.-25.08.2006, Vienna, Austria]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[This paper deals with the speciation of U(VI) associated with the cells of bacterial strains isolated from extreme habitats as function of pH. For this propose, a combination of synchrotron-based X-ray absorption spectroscopy (XAS), time-resolved laser-induced fluorescence spectroscopy (TRLFS), transmission electron microsocpe (TEM) coupled with energy dispersive-X ray (EDX) analysis and electron diffraction were used. XAS analysis indicated that the effect of pH on the local coordination of U in the U-complexes formed by the different bacterial strains is species specific. No structural differences were found between the U complexes formed by three different exo-types of Acidothiobacillus ferrooxidans at pH 2, 3 and 4.5. In contrast, the cells of Bacillus sphaericus JG-B7, Microbacterium oxydans M2, and Sphingomonas sp. S15-S1 precipitate U(VI) as a meta-autunite-like phase at pH 4.5, probably due to the release of the inorganic phosphate from the cells. At pH 2, the U is coordinated to the organic phosphate groups of the cells of the listed bacteria. Both organic and inorganic uranyl / bacterial complexes were formed at pH 3. TEM/EDX analysis confirm these results and showed strain-specific extracellular and/or intracellular uranium accumulation to varying degrees. We applied Iterative Target Test Factor Analysis to determine the uranium speciation at different pH values quantitatively from the EXAFS spectra. Different hypothesis explaining the different coordination chemistry of uranium to bacteria as a function of pH of uranium solution in terms of solubility of m-autunite and/or microbial activity will be discussed.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[In order to expand the photon version of the Monte Carlo transport program AMOS PE to an adjoint photon version the theory of adjoint radiation transport is resumed and evaluated in this regard. All relevant photon interactions, photoelectric effect, coherent scattering, incoherent scattering and pair production, are taken into account as proposed in the EPDL 97. In order to simulate pair production and to realise physical source terms with discrete energy levels, an energy point detector is used. To demonstrate the qualification of AMOS Pt a simple air-over ground problem is simulated by both the forward and the adjoint programs. The results are compared and total agreement is shown.]]></dc:description>

<dc:source><![CDATA[Journal of Organic Chemistry 71(2006)4, 1399-1406]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[A series of novel S,N-heterocyclic (thiazolyl) substituted carboximidamides 3 and 4 was synthesized in yields up to 82% from specific triazinium salts 1 and primary or secondary amines 2 which additionally bear pyridine or imidazole units. These carboximidamides are used as tailor-made ligands for the complexation of Cu(II) and Zn(II). The coordination behavior of 3 and 4 and the properties of the resulting metal complexes are affected a significant extent especially by the nature of these amine substituents. The most important structural feature of the novel complexes is that the ligation of the metal cations is achieved by a 1,3,5-triazapentadienyl anion system, compare the X-ray structure of the model complex Cu-4d. Analogous Zn(II) complexes 5, 6a, 6b, 6c, 7a, and 7b were obtained from carboximidamides 3, 4a, 4b, 4c, 4d, and 4e after reaction with diethylzinc. Interestingly, these Zn(II) complexes possess an intrinsic activity to catalyze the copolymerization of cyclohexene oxide and carbon dioxide to give polycarbonates 15 (TON up to 113; Turn Over Number: moles of substrate 14 consumed per moles of zinc. Molecular weights: up to 206â103 Da). Contaminations of 15 by polyethers are produced only in remarkably small amounts.]]></dc:description>

<dc:description><![CDATA[Die Untersuchung der Freisetzung, des Transports und der Sedimentation von Mineralwollpartikeln in der Sumpfströmung gewinnt wachsende Beachtung bezüglich des Langzeitverhaltens der Notkühlsysteme von Druck- und Siedewasserreaktoren. Das bei einem Leck freigesetzte Isolationsmaterial besteht bezüglich Größe, Form, Konsistenz und anderen Eigenschaften aus einem Gemisch von sehr unterschiedlichen Partikeln. Ein Teil dieser freigesetzten Fasern kann in den Sumpf gelangen und durch Anlagerung an den Sumpfsieben die Notkühlung beeinträchtigen. Offene Fragen von allgemeinem Interesse sind z.B. die Ablagerung von Isolationsmaterial, die mögliche Re-Suspension und der Transport in einer Wasserströmung, die Anlagerung des Isolationsmaterials an die Sumpfsiebe und der daraus resultierende Differenzdruck.
Ein gemeinsames durch das BMWA gefördertes Forschungsprojekt in Zusammenarbeit mit dem Institut für Prozesstechnologie, Automatisierung und Messtechnik (IPM) in Zittau befasst sich mit der experimentellen Untersuchung und der Entwicklung von CFD-Modellen zur Beschreibung von Partikeltransportphänomenen in der Kühlmittelströmung. Während die Experimente am IPM Zittau durchgeführt werden, ist die theoretische Arbeit am Forschungszentrum Rossendorf konzentriert.
In der vorliegenden Arbeit werden die grundlegenden Konzepte der CFD-Modellierung beschrieben und erste Ergebnisse einschließlich Machbarkeitsstudien beschrieben.]]></dc:description>

<dc:source><![CDATA[21st General Conference of the EPS Condensed Matter Division, 27.-31.03.2006, Dresden, Deutschland]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Laser pulse induced field assisted precessional switching in exchange coupled mesoscopic NiFe/FeMn striplines has all-optically been triggered and magneto-optically observed in real time with switching times down to 500 ps. A fast decoupling of the exchange bias bilayer launches coherent precession of the magnetization of the ferromagnetic layer of the exchange bias system. By properly choosing the initial equilibrium orientation the optical unpinning of the bilayer can induce complete magnetization switching. Stroboscopic time domain imaging of the switching event has been realized by a sophisticated synchronization scheme of a magnetic preset pulse and both the optical pump and probe pulses, respectively. The observed laser assisted switching can be well described by the Landau-Lifshitz-Klaasen-van Peppen equation combining precessional and thermally activated spin dynamics.]]></dc:description>

<dc:title><![CDATA[Influence of energetic ions and neutral atoms on the L10 ordering of FePt films]]></dc:title>
<dc:source><![CDATA[IBMM 2006, 18.-22.09.2006, Taormina, Italy]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[With respect to future magnetic recording materials, the L10-ordering of stoichiometric FePt films (70 nm) deposited on amorphous SiO2 by dc magnetron co-sputtering has been studied. A low deposition rate (0.6 Å/s) and Ar pressure (0.3 Pa) was used. The kinetics of structural A1 - L10 transition and the degree of ordering have been investigated with in-situ X-ray diffraction at the Synchrotron beam line ROBL at ESRF. The transition to almost complete ordered L10 films with an ordering parameter S > 0.8 has been obtained at low temperatures of (320 +/- 20)°C. An additional post-deposition ion irradiation with He ions at RT or at 250°C (50 keV, 1x1015 - 3x1016 cm-2) does not influence this low transition temperature. Theoretical calculations reveal that for our experimental conditions no thermalization of the sputtered atoms and the reflected Ar neutrals in the plasma occur; thus, a considerable fraction of energetic ions and neutrals meet the substrate with energies partly exceeding the displacement threshold. The low transition temperature is explained in the reduction of the activation energy for atomic reordering by point defects which becomes mobile at temperatures higher or equal to 250°C. Using operating conditions with a strong thermalization (deposition at 2 Pa), the FePt film showed an increase of the transition temperature to 400°C and a reduced film density. Finally, the results of first experiments towards patterned L10 ordered FePt layers will be reported.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[This paper presents results of the photocathode cooling system test of the 3½ cell SRF gun at the Forschungszentrum Rossendorf. The SRF gun will produce short electron pulses with high bunch charges and low transverse emittance. The requirement for the superconducting electron linear accelerator in Rossendorf (ELBE) is to provide a low emittance electron beam up to 1mA current and 9.5 MeV energy. Additionally, it will easily operate in continuous wave (cw) mode because of the low RF power losses in the superconducting material. Therefore, the normal conducting copper cathode must be cooled by liquid nitrogen in order to preserve the temperature of the cavity at 2.2 K. The estimated power input from the RF field into the cathode could be more than 10 W [1]. First results of temperature measurements of the photo cathode respectively from the cooling system at a heat load up to 30 W are presented.]]></dc:description>

<dc:description><![CDATA[At the clinical heavy ion treatment facility, which is under construction in Heidelberg, beams of He will be used for tumor irradiation. These will be monitored by means of in-beam PET for quality assurance. This requires a precise knowledge of the spatial distribution of beam induced positron emitters in the irradiated volume. For this an experiment at the Gesellschaft für Schwerionenforschung (GSI) with three mono-energetic {rm<sup>3</sup>He}-beams of  130.03 it A\rm M it e\rm V 
to 207.92 it A\rm Mit e\rm V and mean intensities varying from 2.0 cdot 10<sup>8</sup> to  3.5 cdot 10<sup>8</sup> ions/s has been carried out. The beams were stopped in homogeneous thick targets consisting of lucite, graphite and gelatine, which were placed in the center of the field of view of the PET-scanner  at the experimental carbon ion therapy at GSI [1]. Results on the production rate and the spatial distribution of {\rm<sup>3</sup>He} ion induced  beta<sup>a</sup>-activity will be presented. From these, the accuracy and resolution for determining the range of the {rm<sup>3</sup>He} primary beams is deduced. Furthermore, energy dependent cross sections for different reaction channels leading to positron emitters will be estimated from the experimental data.]]></dc:description>

<dc:date>2007</dc:date>
<dc:description><![CDATA[The nucleation and growth of Ti2AlN thin films on MgO(111) substrates during dual DC reactive magnetron cosputtering from Ti and Al targets in an Ar/N2 atmosphere at a substrate temperature of 690°C have been investigated . Time and thickness dependent in situ specular x-ray reflectivity and x-ray diffraction (XRD) in coplanar scattering geometry in combination with cross-sectional transmission electron microscopy and Rutherford backscattering spectroscopy revealed the formation of competing phases. It is found that initially an ~380-Åthick epitaxial cubic (Ti1-xAlx)Ny layer of substoichiometric composition forms with a layer-by-layer growth mode. Nitrogen-vacancy driven diffusion of Ti and Al leads to spinodal decomposition of this metastable solid solution into nano-sized cubic TiNy and AlNy domains as well as to a solid-state reaction where Mg2(Al:Ti)O4 spinel forming below the interface to the MgO(111). Spatial and temporal fluctuations of the nitrogen activity on the (Ti1-xAlx)Ny surface at higher thicknesses yield thermodynamically favored Ti2AlN nucleation and polycrystalline growth. Concurrent Ti2AlN inward grain growth by diffusion of weakly bonded Al atoms along the Ti2AlN basal planes reduces the thickness of the phase-separated (Ti1-xAlx)Ny layer to ~60 Å. Individual Ti2AlN grains retain local epitaxy to the substrate with vertical grain sizes in the range of the final film thickness.]]></dc:description>

<dc:date>2007</dc:date>
<dc:description><![CDATA[The transition temperature for the A1 to  L10 phase transition of magnetron sputter deposited FePt films in the thickness range between 35 and 130 nm is investigated. Large ordering factors up to S = 0.93 are observed either for a deposition at T = 350°C or a post-deposition annealing at 400°C. These low ordering temperatures are explained by a defect enhanced atomic site exchanges induced by the impact of energetic ions. Due to the use of amorphous substrates no preferential grain orientation and thus only a weak magnetic anisotropy could be achieved.]]></dc:description>

<dc:description><![CDATA[We report on the study of a two-dimensional dot lattice structures which was produced on GaAs and Si (001) substrates using a Ga<sup>+</sup> focused ion beam in normal incidence with a spot size of about 50 nm, an energy of 25 keV and a dose of 10<sup>14</sup> cm<sup>-2</sup>. The fabricated 2D-lattice structures consist of dots of almost circular shape with an area of about 2000 nm<sup>2</sup> and a period of 250x250 nm<sup>2</sup>. The whole implanted area has a size of less than 0.2 mm<sup>2</sup>. We have investigated the interaction of the implanted ions with the host lattice as a function of the implantation conditions using grazing incidence diffraction at the ID10 and ID1 beam lines at the ESRF. The low-dose implantation creates interstitials and vacancies below the surface generating a weak displacement field resulting in a 2D periodical strain field in case of Si substrate. For the GaAs substrate we found a much more complex scattering pattern which depends on the in-plane orientation of the 2D dot lattice with respect to the crystallographic orientation of the crystal. A much stronger scattering contrast can be found if the 2D dot lattice misaligned by 14° degree. A simulation taking the interaction between the implanted ions and the host lattice into account shows an enhanced channelling of the ions into low-index crystallographic directions. Thus the dependence of the profile of implantation damage on the crystalline structure influences the scattering patterns.]]></dc:description>

<dc:source><![CDATA[European Journal of Mechanics B - Fluids 25(2006), 894-908]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The intention of the "von Karman sodium" (VKS) experiment is to study the hydromagnetic dynamo effect in a highly turbulent and unconstrained flow. Much effort has been devoted to the optimization of the mean flow  and the lateral boundary conditions in order to minimize the critical magnetic Reynolds number and hence the necessary motor power. The main focus of this paper lies on the role of "lid layers", i.e. layers of liquid sodium between the impellers and the end walls of the cylinder. First, we study an analytical test flow to show that lid layers can have an ambivalent effect on the efficiency of the dynamo. The critical magnetic Reynolds number shows a flat minimum for a small lid layer thickness, but increases for thicker layers. For the actual VKS geometry it is shown that static lid layers yield a moderate increase of the critical magnetic Reynolds number by approximately 12 per cent. A more dramatic increase by 100 until 150 per cent can occur when some rotational flow is taken into account in those layers. Possible solutions of this problem are discussed for the real dynamo facility.]]></dc:description>

<dc:description><![CDATA[A Multiple Field Multiple Size Group Model for industrial poly-dispersed gas-liquid flows has been developed in the commercial code CFX10.0. This model is based on the multi-fluid approach and the population balance method and is efficient for solving large-scale industrial flow problems. Compared with the previous CFX Multiple Size Group Model, the current model is applicable for inhomogeneous flow. In the first part, the model concepts and governing equations are presented.]]></dc:description>

<dc:description><![CDATA[The current status of the pulsed-magnet program of the High Magnetic Field Laboratory at Dresden (HLD) is reported. The non-destructive pulsed magnets for the HLD include a wide spectrum of coils designed for energies between 1 and 46 MJ, magnetic fields of 60 - 100 T, and pulse durations of 10 - 1000 ms. Magnet bores from 20 to 40 mm will accommodate different experimental setups. A universal core design has been developed at the HLD for these pulsed magnets. In spite of a strong external mechanical structure, our magnets are designed in a compact way. That allows to use this design both for inner and outer coils in multi-coil configurations. The core design has been successfully examined for a number of magnets for fields between 60 and 65 T. Already some user magnets for first scientific experiments have been installed and tested. The construction of a 9 MJ / 70 T mono-coil magnet has been accomplished. First test results are presented. The design of a two-coil 46 MJ magnet for magnetic fields above 85 T has been completed. Different aspects of the pulsed-magnet design and coil construction are discussed. Important issues of the coil design are numerical simulations of the pulsed-magnet behavior. Both analytical approximations and finite element analysis are used for these simulations at the HLD. Some simulation results are presented.

<dc:description><![CDATA[The complex formation of curium(III) with L2-Aminobutyric acid was characterized by time-resolved laser-induced fluorescence spectroscopy (TRLFS) at trace Cm(III) concentrations (3x10-7 M). 
The different curium(III) species, MpHqLr, identified are characterized by their individual luminescence spectra and luminescence lifetimes. The following formation constants were determined log β101 = 5.17 ± 0.07, log β102 = 9.00 ± 0.07, and log β103 = 11.30 ± 0.09 at ionic strength I = 0.5 M.  Possible structures of the curium aminobutyrate species will be discussed on the basis of the luminescence lifetime measurements and the magnitude of the formation constants.]]></dc:description>

We present results on the design and application of a DC magnetic field in order to control this pouring process. Based on numerical simulations and modeling cold metal pre-experiments, DC fields were designed and installed in various casting processes under industrial conditions. The statistics of the casting products show a significant improvement of the casting parts quality.

<dc:description><![CDATA[Es wird ein Überblick über die Möglichkeiten der elektromagnetischen Strömungskontrolle für Anwendungen in der Giessereitechnik und in der Metallurgie gegeben, namentlich zur Kontrolle der Formfüllung beim Feinguß, zur elektromagnetischen Beeinflussung der Strömungsstruktur in Flüssigmetall-Zweiphasenströmungen sowie bei der Erstarrung von Legierungen unter Magnetfeldeinfluß. Insbesondere wird auf die Bedeutung von Modellexperimenten mit metallischen Modellschmelzen hingewiesen, die einen wesentlichen Beitrag zum Verständnis der Strömungs-vorgänge in praxisrelevanten Anordnungen liefern können. Betrachtet man für die industriellen Anwendungen realistische Parameterbereiche liefern diese Wassermodelle liefern allerdings oft falsche Ergebnisse und sind völlig wertlos für Untersuchungen zur elektromagnetischen Strömungskontrolle.]]></dc:description>

<dc:source><![CDATA[Journal of Applied Physics 98(2005)4, 043508]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Defects in He-implanted n-type 6HSiC samples have been studied with deep-level transient spectroscopy. A deep-level defect was identified by an intensity with a logarithmical dependence on the filling pulse width, which is characteristic of dislocation defects. Combined with information extracted from positron-annihilation spectroscopic measurements, this defect was associated with the defect vacancy bound to a dislocation. Defect levels at 0.38/0.44  eV (E1/E2), 0.50, 0.53, and 0.64/0.75  eV (Z1/Z2) were also induced by He implantation. Annealing studies on these samples were also performed and the results were compared with those obtained from e-irradiated (0.3 and 1.7  MeV) and neutron-irradiated n-type 6HSiC samples. The E1/E2 and the Z1/Z2 signals found in the He-implanted sample are more thermally stable than those found in the electron-irradiated or the neutron-irradiated samples.]]></dc:description>

<dc:source><![CDATA[Journal of Crystal Growth 285(2005), 249]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Thin poly-crystalline silicon films are attractive for the fabrication of active matrix liquid crystal displays.  We propose the use of flash lamp annealing to recrystallize amorphous silicon layers on glass substrates as a low cost manufacturing route.  In this process amorphous silicon can be crystallized both by solid phase crystallization (SPC) and  in the super lateral growth (SLG) regime. We present a thermal model which incorporates the phase transitions during annealing and we have shown that predictions from the model are in good agreement with experimental observations.  In addition, the model is a valuable aid to optimizing the process conditions.]]></dc:description>

<dc:source><![CDATA[Surface &amp; Coatings Technology 200(2005), 1-6]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[For specific applications of hard coatings, the microstructure (or nanostructure) has to be tailored for optimum performance. This requires information about the mechanisms of growth and the connection between the microstructure and the deposition parameters. In order to obtain this knowledge, in situ real time growth studies of magnetron-sputtered thin films were carried out. A growth chamber, equipped with two magnetrons and Kapton windows for X-ray diffraction and reflectivity, was mounted on a six-circle goniometer at a synchrotron beam line at ESRF in Grenoble. As an example, X-ray diffraction measurements were carried out in situ during growth of TiN to follow the development of the microstructure. Recrystallization was identified as the mechanism which controlled the development of texture. The driving force for these texture changes arose from minimalization of the sum of the surface energy and the strain energy of the individual grains. As another example, the heteroepitaxial growth of TiN on MgO(001) was studied. BraggBrentano as well as grazing-incidence in-plane wide angle scattering was used to establish the pseudomorphic growth of TiN to the underlying MgO(001). Using real-time specular X-ray reflectivity, layer-by-layer growth was observed, with the surface roughening decreasing with an increase in the deposition temperature. The growth of nanocrystalline Au was also investigated. Among the results we found that changes in the (111) fiber texture arose from grain rotations.]]></dc:description>

<dc:source><![CDATA[Acta Physica Polonica A 107(2005), 745-752]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Recent investigations of ultra fine-grained metals (Cu, Fe, Ni) performed within a Prague-Rossendorf-Ufa collaboration will be reviewed. The specimens were prepared by severe plastic deformation: the high-pressure torsion and equal channel angular pressing. Positron annihilation spectroscopy was used as the main method including (i) the conventional lifetime and the Doppler broadening measurements with 22Na and (ii) the slow-positron implantation spectroscopy with the Doppler broadening measurement. Other methods were also involved: transmission electron microscopy, X-ray diffraction, and microhardness. First, the mean grain size was determined and defects were identified in the as-deformed materials. Defects concentration and spatial distribution were studied in detail. Dislocations situated in distorted regions along grain boundaries, and a few-vacancy clusters distributed homogeneously inside dislocations-free grains, were observed in the ultra fine-grained Cu, Fe, and Ni. Subsequently, the thermal evolution of the ultra fine-grained structures during isochronal annealing was studied.]]></dc:description>

<dc:source><![CDATA[Journal of Colloid and Interface Science 300(2006), 482-490]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The speciation of Eu complexed with polyacrylic acid (PAA) and alumina-bound PAA
(PAAads) was studied at pH=5 in 0.1M NaClO4. Structural parameters were obtained from 7F0→5D0 excitation spectra measured by Laser Induced Fluoresence ectroscopy as well as from Eu LIII edge Extended X-ray Absorption Fine Structure (EXAFS) spectra. The mode of coordination was also investigated by Infra Red pectroscopy. To elucidate the nature of the complexed species, Eu-acetate complexes were used as references. The spectroscopic techniques show that two carboxylate groups with 2-3 (EuPAA) and 4-5 (EuPAAads) hydration water molecules are coordinated to Eu in the first coordination sphere. For EuPAAads, the coordination between carboxylate groups and Eu appears to be bidendate. A similar coordination is probable for EuPAA but the EXAFS data indicate a sligthly distorted coordination. The results show that the degree of freedom of carboxylate groups is not the same for free or adsorbed PAA. For PAA, the degree of freedom is constrained by the flexibility of the methylene chain. When PAA is adsorbed on alumina, the polymer chains cannot any more be treated as independent chains. One may rather assume formation of aggregates that form an organic layer at the mineral surface presenting a complex arrangement of carboxylate groups.]]></dc:description>

<dc:title><![CDATA[Experimente zur CFD-Validierung für horizontale Zweiphasen-Strömungen]]></dc:title>
<dc:source><![CDATA[Seminar des Lehrstuhl für Thermodynamik, 09.01.2006, Garching, München, Germany]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Zur Weiterentwicklung und Validierung von CFD-Codes bei Zweiphasen-Strömungen wurden am Forschungszentrum Rossendorf zwei horizontale Luft/Wasser-Strömungskanäle aufgebaut. Die Teststrecken, mit unterschiedlichem rechteckigen Querschnitt, wurden für den Einsatz optischer Messverfahren aus Acrylglas konstruiert. Die Versuche fanden bei Umgebungsdruck und -temperatur statt.

Die erste Anlage wurde für Vorversuche genutzt: An dieser konnte die Instrumentierung getestet und weiterentwickelt werden. Es wurden optische Messungen mit einer Hochgeschwindigkeitskamera durchgeführt und mit dynamischen Druckmessungen synchronisiert. Aus den entstandenen Bildsequenzen wurde die Phasengrenzfläche durch eigenentwickelte Algorithmen ermittelt. Außerdem wurden Geschwindigkeitsfelder in einem Schwall mit PIV (Particle Image Velocimetry) gemessen.

Der zweite Testkanal profitierte von den Erfahrungen an der ersten Anlage: Seine Konstruktion wurde für die Validierung von CFD-Codes optimiert. Eine spezielle Einlaufkomponente sorgt für definierte und konstante Randbedingungen am Eintritt. Zudem kann die Kanallänge bis auf 14 m erweitert werden. Es werden erste qualitative Ergebnisse gezeigt, so zum Beispiel Visualisierungen verschiedener Strömungsformen.]]></dc:description>

<dc:description><![CDATA[Association constants for the interaction of almost insoluble substrates with triphenylene ketal-based receptors in toluene have been determined by means of an extraction method employing the corresponding radio-labelled substrates. Flexible and more polar receptors tend to aggregate and exhibit inferior extraction qualities. Binding constants in toluene were found to be in the range 10<SUP>5</SUP>10<SUP>7</SUP>M<SUP>-1</SUP> which is significantly higher than in dichloromethane.
X-ray analyses indicate the direct participation of a water molecule in the binding process, which may account for the surprisingly small effect of moisture in the solvent on the stability of the complexes.]]></dc:description>

<dc:source><![CDATA[Physics of Plasmas 13(2006), 122308]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Magnetic fields of planets, stars, and galaxies result from self-excitation in moving electro-conducting fluids, also known as dynamo effect. This phenomenon was recently experimentally confirmed in the Riga dynamo experiment, consisting of a helical motion of sodium in a long pipe followed by a straight back-flow in a surrounding annular passage, which provided adequate conditions for magnetic field self-excitation. We report here on the first attempt to simulate computationally the Riga experiment. The velocity and turbulence fields are modelled by a finite-volume Navier-Stokes solver using a Reynolds-Averaged-Navier-Stokes (RANS) turbulence model. The magnetic field is computed by an Adams-Bashforth finite-difference solver. The coupling of the two computational codes, although performed sequentially, provides an improved understanding of  the interaction between the fluid velocity and magnetic fields in the saturation regime of the Riga dynamo experiment under realistic working conditions.]]></dc:description>

<dc:description><![CDATA[X-ray absorption, resonant x-ray emission, and x-ray photoelectron spectra of the valence band
and core levels have been measured for LixCoO2 (0.6 < x < 1.0). Resonant O K x-ray emission
spectra of LiCoO2 showed localized excitonic states due to a dd transition between unoccupied and
occupied Co 3d states. On the base of measurements of Co 3s x-ray photoelectron and Co 2p and
O 1s x-ray absorption spectra it was established that in defective cobaltites the electronic holes are
localized mainly in O 2p states. Metallic character of conductivity of defective cobaltites LixCoO2 is
confirmed by a combination of x-ray photoelectron and O 1s x-ray absorption spectra. An evidence
of phase separation in LixCoO2 has been found.]]></dc:description>

In this work, thermophysical properties (density, viscosity and electrical conductivity) of liquid Al96Cu4, Al80Cu20, Al70Cu30, and AlCu4TiMg (wt.%) alloys have been measured in a wide temperature range.
The anomalies with respect to the concentration dependence of the electrical conductivity are explained in terms of the sd hybridization model. A comparison with data and scaling relations being available in the literature is given.]]></dc:description>

<dc:description><![CDATA[The fluoroalkyl-containing tropane derivative 2β-carbo-2-fluoroethoxy-3β-(4-bromo-phenyl)tropane (MCL-322) is a highly potent and selective ligand for the dopamine transporter (DAT). The compound was labeled with the short-lived positron emitter <SUP>18</SUP>F in a single step by nucleophilic displacement of the corresponding tosylate precursor MCL-323 with n.c.a. [<SUP>18</SUP>F]fluoride. The positron emission tomography (PET) radiotracer 2βcarbo-2-[<SUP>18</SUP>F]fluoroethoxy-3β-(4-bromo-phenyl)tropane [<SUP>18</SUP>F]MCL-322 was obtained in decay-corrected radiochemical yields of 30-40 % at a specific radioactivity of 1.6-2.4 Ci/µmol (60-90 GBq/µmol) at the end-of-synthesis (EOS). Small animal PET, ex vivo and in vivo biodistribution experiments in rats demonstrated a high uptake in the striatum (3.2 % ID/g) 5 min after injection, which increased to 4.2 % ID/g after 60 min. The uptake in the cere¬bellum was 1.8 % ID/g and 0.6 % ID/g after 5 min and 60 min post injection, respectively. Specific binding to DAT of [<SUP>18</SUP>F]MCL-322 was confirmed by blocking ex¬periments using the high affinity DAT ligand GBR 12909. The radiopharmacological characterization was completed with metabolite and autoradiographic studies confirming the highly selective uptake of [<SUP>18</SUP>F]MCL-322 in the striatum.
It is concluded that the simple single-step radiosynthesis of [<SUP>18</SUP>F]MCL-322 and the promising radiopharmacological data make [<SUP>18</SUP>F]MCL-322 an attractive candidate for the further development of a PET radiotracer potentially suitable for clinical DAT imaging in the human brain.]]></dc:description>

The write performance was investigated in metal-oxide-semiconductor capacitors by means of capacitance measurements. With the experimental data and calculations using a floating-gate-like approach, the distribution of the tunneling oxide thickness dtox can be obtained in high precision confirmed by high-angle annular dark-field scanning transmission electron microscopy imaging. The evolution of dtox during heat treatment is discussed in terms of Ostwald ripening; i.e., dtox increases with annealing time.]]></dc:description>

<dc:date>2008</dc:date>
<dc:description><![CDATA[For modeling multi-phase where the disperse phase play a major role for determining the flow structure and inter phase transfer quantities, the size distribution of the particles has to be considered. This can be done by extension of the mass balance equation to a population balance equation. In this work, a least squares spectral method is tested for predicting the evolution of the disperse phase in a vertical two phases bubbly flow. The least squares spectral method consists in minimizing the L2 norm of the residual over the simulation domain. The results are compared with experimental data obtain for two different initial bubble distribution.]]></dc:description>

<dc:description><![CDATA[An improved Stillinger-Weber-type potential for Ge is developed by adjusting the three-body parameters in such a manner that lattice parameter and cohesive energy are preserved, and the elastic constants and the melting point are reproduced satisfactorily. The dependence of the equilibrium concentration and the diffusivity of vacancies on the temperature as well as the contribution of vacancies to self-diffusion are determined by atomistic simulations and by thermodynamic considerations. The calculations are performed in the temperature range between 600 and 1100 K. The enthalpies and entropies for formation and migration are estimated. Similar investigations are performed for self-interstitials in order to check whether their contribution to self-diffusion in Ge can be neglected, as shown experimentally. Finally, the self-diffusion coefficient and the equilibrium concentration of vacancies are compared with experimental data from the literature.]]></dc:description>

<dc:description><![CDATA[Magnetron sputtered film stacks of 5nm Ta/50(15)nm NiMn/20nm Fe19Ni81 /5nm Ta deposited at Si/SiO2 substrates were subsequently irradiated with He+ ions (30 keV, 1e15 - 3e16 cm-2). Using synchrotron X-ray diffraction and reflectivity, the transition from the paramagnetic NiMn phase to the chemically ordered, antiferromagnetic L10 phase during annealing was studied. The transformation to a dominating L10 ordered NiMn film takes place between 300-400°C irrespective of the irradiation.  Ion irradiation at low fluences offers beneficial effects with respect to a reduction of the mosaicity for both, the NiMn and the permalloy film, and a smoothening of internal interfaces.]]></dc:description>

<dc:date>2006</dc:date>
<dc:description><![CDATA[Self-organized ripple formation during ion erosion of a Si wafer is used to create a template system with a well defined roughness of uniaxial symmetry. By using special buffer layers subsequent thin magnetic film deposition by molecular beam epitaxy leads to a periodically modulated magnetic thin film with drastically modified magnetic properties with respect to a nominally flat film of the same thickness. In the case of Permalloy thin films, an enhancement of the uniaxial in-plane anisotropy by approximately a factor of 20 is observed (see Fig. 2). The enhancement can be explained by a combination of step induced dipolar and magnetocrystalline surface anisotropy contributions.
If a ferromagnet/antiferromagnet-bilayer is deposited a superposition of ripple-induced uniaxial anisotropy and exchange coupling induced unidirectional anisotropy is observed. Since the direction of the unidirectional anisotropy depends only on the magnetic field direction during a field cooling procedure any angle between both anisotropy contributions can be set. The observed angular dependence of the magnetization reversal behavior is in perfect agreement with simulations based on the Stoner-Wolfarth coherent rotation model.]]></dc:description>

<dc:description><![CDATA[Self-organized ripple formation during ion erosion of a Si wafer is used to create a template system with a well defined roughness of uniaxial symmetry. By using special buffer layers subsequent thin magnetic film deposition by molecular beam epitaxy leads to a periodically modulated magnetic thin film with drastically modified magnetic properties with respect to a nominally flat film of the same thickness. In the case of Permalloy thin films, an enhancement of the uniaxial in-plane anisotropy by approximately a factor of 20 is observed (see Fig. 2). The enhancement can be explained by a combination of step induced dipolar and magnetocrystalline surface anisotropy contributions.
If a ferromagnet/antiferromagnet-bilayer is deposited a superposition of ripple-induced uniaxial anisotropy and exchange coupling induced unidirectional anisotropy is observed. Since the direction of the unidirectional anisotropy depends only on the magnetic field direction during a field cooling procedure any angle between both anisotropy contributions can be set. The observed angular dependence of the magnetization reversal behavior is in perfect agreement with simulations based on the Stoner-Wolfarth coherent rotation model.]]></dc:description>

<dc:description><![CDATA[Low-temperature photoluminescence spectroscopy has revealed a series of features labeled S1, S2, S3 in n-type 6H-SiC after neutron and electron irradiation. Thermal annealing studies showed that the defects S1, S2, S3 disappeared at 500 °C. However, the well-known D1 center was only detected
for annealing temperatures over 700 °C. This experimental observation not only indicated that the defects S1, S2, S3 were a set of primary defects and the D1 center was a kind of secondary defect, but also showed that the D1 center and the E1, E2 observed using deep level transient spectroscopy
might not be the same type of defects arising from the same physical origin.]]></dc:description>

<dc:description><![CDATA[First experimental results more than one decade ago demonstrated the visible room temperature luminescence of Si nanocrystals in implanted SiO2 or porous Si which triggered the strong interest in Si nanocrystal based systems and their properties. Basic fundamental questions concerning quantum confinement effects in indirect semiconductors as well as potential applications such as light emission from electrically excited Si nanocrystals, energy transfer to Er 3+ ions, and non volatile Si NC based memories also stimulated the broad scientific interest in this material system. For clarifying the origin of the observed luminescence signal as well as for applications, tight control over the size of the nanocrystals is essential. The talk will give an overview about ways for size controlled Si nanocrystals. Basic properties as well as various applications including memory applications will be discussed in details.]]></dc:description>

<dc:description><![CDATA[An isotropic S = 1/2 Heisenberg antiferromagnetic (AFM) chain with uniform nearest-neighbor exchange coupling represents one of the paradigm models of quantum magnetism. Its ground state is a spin singlet and the dynamics are determined by a gapless two-particle continuum of spin- 1/2 excitations, commonly referred to as spinons. Since the S = 1/2 AFM chain is critical, even small perturbations can considerably change fundamental properties of the system. One of the most prominent examples is the S = 1/2 AFM chain perturbed by an alternating g-tensor and the Dzyaloshinskii-Moriya interaction; this situation is realized experimentally in the copper pyrimidine dinitrate, Cu-PM. In the presence of such interactions, application of a uniform external field H induces an effective transverse staggered field h ∝ H, which leads to the opening of an energy gap Δ ∝ H<sub>2/3</sub>. Here we report on the excitation spectrum in Cu-PM measured using submillimeter wave electron spin resonance (ESR) spectroscopy in fields up to 25 T [1]. Ten excitation modes are resolved in the low-temperature spectrum. The field-induced gap is measured directly. Signatures of three breather branches and a soliton, as well as those of several multi-particle excitation modes are identified. The experimental data are sufficiently detailed to make a very accurate comparison with predictions based on the quantum sine-Gordon field theory [2]. In addition, a new theoretical concept proposed recently by Oshikawa and Affleck [3] has been tested. Their theory, based on bosonization and the self-energy formalism, can be applied for precise calculation of ESR parameters of S = 1/2 AFM chains in the perturbative spinon regime. Excellent quantitative agreement between the theoretical predictions and experiment is obtained [4].

<dc:source><![CDATA[Physical Review B 73(2006)18, 184410]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The static and dynamic magnetic properties, especially the magnetic damping behavior, have been investigated as a function of saturation magnetization in thin Permalloy films. Ion implantation doping with Cr in the percentage regime has been used to effectively reduce the Curie temperature and thus the saturation magnetization at room temperature. In order to understand the magnetic modifications the changes in stoichiometry but also the ion induced structural changes have been addressed. As a function of fluence first an improvement of the (111) fiber texture, then a lattice expansion and finally a partial amorphization of the interface near region of the Permalloy layer is found. The region of amorphization can be understood quantitatively by the concentration profiles as a function of depth in combination with irradiation induced damage formation. The magnetic properties change correspondingly. For increasing Cr doping a drop in saturation magnetization and a decrease of the uniaxial magnetic anisotropy is observed. For a fluence of 0.8 x 10^16 Cr/cm^2 (4 at.%) the magnetic damping parameter  increases by a factor of 7. This strong increase is mainly caused by the reduction of the saturation magnetization and the altered sample morphology.]]></dc:description>

Curium species of the type MpHqLr were identified in the L-Threonine- and O-Phospho-L-Threonine system. These complexes are characterized by their individual luminescence spectra and luminescence lifetimes. The following formation constants were determined a) for  L-Threonine: log β101 = 6.72 ± 0.07, log β102 = 10.22 ± 0.09, and log β1-22 = -(7.22 ± 0.19) at ionic strength I = 0.5 M and b) for O-Phospho-L-Threonine: log β121 = 18.03 ± 0.13 and log β111 = 14.17 ± 0.09 at ionic strength I = 0.154 M. Possible structures of the identified curium species will be discussed on the basis of the luminescence lifetime measurements and the magnitude of the formation constants.]]></dc:description>

<dc:description><![CDATA[Shape-memory alloys (SMA) represent a class of metallic materials that has the capability of recovering a previously defined initial shape when subjected to an adequate thermomechanical treatment. Annealing of a Ti-rich Ni–Ti alloy has been followed by in situ high temperature diffraction in order to register the texture as well as the microstrain/microstress evolution. This type of study is relevant to the envisaged applications, because the type of preferential orientation and the corresponding anisotropic response of the material conditions contributes to the success of the SMA application. In the present study we have tested the feasibility of high temperature pole figures determination at ROBL (BM20) at the ESRF, and we have shown that there is a relation between the preferential orientation changing and the structural evolution taking place during annealing.]]></dc:description>

<dc:description><![CDATA[Die Positronen-Emissions-Tomographie (PET) hat sich als bildgebendes Verfahren in der klinischen Routine sowie der medizinischen, biologischen und pharmazeutischen Forschung etabliert.
Daraus ergibt sich die Notwendigkeit, Mediziner sowie Physiker und Ingenieure mit der speziellen Ausrichtung auf multidisziplinäre Forschungsgebiete der Biologie und Medizin bzw. medizintechnischen Anwendungen im Rahmen ihrer Ausbildung möglichst praxisnah mit dieser Technik vertraut zu machen. Zu diesem Zweck soll ein Versuchsplatz für die PET aufgebaut werden, an welchem die allgemeinen Prinzipien der Computertomographie (CT), die Grundlagen der PET sowie die PET als kernphysikalisches Multiparameter-Messverfahren vermittelt werden. Für die Realisierung dieser Aufgabenstellung gibt es folgende Vorgaben:

- Der Tomograph besteht aus zwei kommerziellen, in Koinzidenz betriebenen, ortsempfindlichen Szintillationsdetektoren.
- Zum Gewinnen vollständiger Projektionsdatensätze wird ein Computer gesteuertes Bewegungssystem für die Translation und die Rotation verwendet.
- Die Signalverarbeitung basiert auf Standardmodulen der kernphysikalischen Messtechnik.
- Zur Gewährleistung einer flexiblen, den unterschiedlichen Anforderungen genügenden Auswertung erfolgt die Speicherung der Daten im Listen-Modus.
- Die tomographische Rekonstruktion mittels gefilterter Rückprojektion ist in die laufende Messung (Online-Betrieb) integriert. Daneben besteht
  die Möglichkeit, die Daten auch nach der Messung in unterschiedlichen Konfigurationen zu rekonstruieren (Offline-Betrieb).

Diese Diplomarbeit soll zudem als Grundlage für das zu erstellende Lehrmaterial fungieren. Dabei wird zuerst auf die Anwendung und Entwicklung der PET eingegangen (Abschnitt 1.1). Im zweiten Kapitel werden die für die PET notwendigen Grundbegriffe erklärt sowie die physikalischen und mathematischen Prinzipien und Wirkungsweisen dargestellt. Daran anschließend wird im dritten Kapitel der Aufbau des PET-Versuchsplatzes beschrieben, wobei auch näher auf die einzelnen ausgewählten Komponenten eingegangen wird. Im vierten Kapitel werden systemspezifische Größen für den Versuchsplatz hergeleitet. Darauf folgend wird in Kapitel 5 die Software detaillierter vorgestellt. Die Ergebnisse der durchgeführten Messungen sind im sechsten Kapitel zu finden. Dabei handelt es sich sowohl um Messungen zur Charakterisierung des Messplatzes als auch um vollständige tomographische Rekonstruktionen von Punktquellen. Abschließend werden die Besonderheiten und Merkmale des aufgebauten Tomographen nochmals zusammengefasst sowie ein Ausblick gegeben (Kapitel 7).]]></dc:description>

<dc:title><![CDATA[Radioimmunotherapy of solid tumors by targeting extra domain B fibronectin: identification of the best-suited radioimmunoconjugate.]]></dc:title>
<dc:source><![CDATA[Clinical Cancer Research 11(2005), 7053s-7063s]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[PURPOSE: The expression of extra domain B (ED-B) fibronectin is always associated with angiogenic processes and can be exclusively observed in tissues undergoing growth and/or extensive remodeling. Due to this selective expression, ED-B fibronectin is an interesting target for radioimmunotherapy of malignant diseases. The aim of this study was to identify the most appropriate ED-B-targeting radioimmunoconjugate for the therapy of solid tumors. EXPERIMENTAL DESIGN: Three ED-B fibronectin-binding human antibody formats of L19 were investigated: dimeric single-chain Fv (approximately 50 kDa), "small immunoprotein" (SIP, approximately 80 kDa), and immunoglobulin G1 (IgG1, approximately 150 kDa). These L19 derivatives were either labeled with I-125 or with In-111 (using MX-diethylenetriaminepentaacetic acid, MX-DTPA). Pharmacokinetics and tumor accumulation of the radiolabeled immunoconjugates were investigated in F9 (murine teratocarcinoma) tumor-bearing mice. Subsequently, dosimetry for the corresponding therapeutic isotopes I-13-1 and Y-90 was done. After testing the myelotoxicity of I-131-L19-SIP and I-131-L19-IgG1 in non-tumor-bearing mice, the therapeutic efficacy of these iodinated antibody formats was finally investigated in F9 tumor-bearing mice. RESULTS: The most favorable therapeutic index was found for I-131-L19-SIP followed by I-131-L19-IgG1. The therapeutic index of all In-111-labeled derivatives was significantly inferior. Considering the bone marrow as the dose-limiting organ, it was calculated that activities of 74 MBq I-131-L19-SIP and 25 MBq I-131-L19-IgG1 could be injected per mouse without causing severe myelotoxicity. The best therapeutic efficacy was observed using I-131-L19-SIP, resulting in significant tumor growth delay and prolonged survival after a single injection. CONCLUSION: Compared with other L19-based radioimmunoconjugates, I-131-L19-SIP is characterized by superior antitumor efficacy and toxicity profile in the F9 teratocarcinoma animal model. These results indicate that ED-B fibronectin-targeted radioimmunotherapy using I-131-L19-SIP has potential to be applied to treatment of solid cancers.]]></dc:description>

<dc:date>2007</dc:date>
<dc:description><![CDATA[It is reported that standing surface-plasmon-polariton (SPP) waves can cause regular thickness undulations of thin polymethyl methacrylate (PMMA) films above a metallic substrate. Ripples and hillock arrays with long-range order were found. Numerical calculations reveal that periodic in-plane temperature profiles are generated in the PMMA due to the non-radiative damping of SPP interference patterns. Atomistic computer simulations on the temperature-gradient-driven mass transport confirm that thermocapillarity is the dominating mechanism of the observed surface patterning.]]></dc:description>

<dc:description><![CDATA[We present a layer resolved magnetic soft x-ray microscopy study of a RKKY coupled Ni81Fe19/Ru/Co90Fe10 layered system where magnetic patterns were imprinted by using a 60 keV fine focused Co ion beam so as to change the coupling from antiferromagnetic to ferromagnetic on a micron scale. Thereby artificial structures in form of stripes with locally varying interlayer exchange coupling are generated. Utilizing the elemental specificity of high-resolution full field soft x-ray microscopy at the Co L3 and the Ni L3 edges we determined the magnetic domain configuration during full magnetization reversal processes locally and layer resolved. In addition to the locally varying interlayer exchange coupling across the Ru layer our data verify a direct exchange coupling within each ferromagnetic layer in the magnetically patterned structure. We conclude that the magnetization reversal behaviour of the irradiated
stripes is largely influenced by the surrounding magnetic film for both, the Permalloy and the Co90Fe10 layer.]]></dc:description>

<dc:description><![CDATA[The properties of pentavalent uranium have not been well understood yet, although a large number of studies have been performed and reported concerning the uranium chemistry up to now, because it is very unstable due to its disproportionation reaction to U(IV) and U(VI). At the moment, the uranyl tricarbonate complex, [UO2(CO3)3]n-, is the only known species that can be stabilized as U(V) in aqueous solution. In order to elucidate the properties of this complex in detail, we performed electrochemical (cyclic voltammetry) and spectroscopic (UV-visible absorption and XAFS) measurement.
From the electrochemical study, it was found that the UVO2+-carbonate complex was stable only in the limited concentration range of 0.8 M < [Na2CO3] < 1.4 M, and a Pt- or Au working electrode is more efficient to reduce UVIO22+ to UVO2+ than a glassy carbon electrode. Therefore, the UVO2+ samples for XAFS measurements were prepared in 1.4 M-Na2CO3 solution by using a Pt-mesh working electrode. The UVO2+ solution was transferred to a glass cuvette that was completely sealed by hot melting to avoid the possibility of any O2-penetration in the cuvette during sample transportation and measurement. The results of XAFS measurement indicated that both uranyl(V) and uranyl(VI) ions form the tricarbonate complex, [UO2(CO3)3]n- (n = 5 for uranyl(V) and 4 for uranyl(VI)). The coordination occurs in a bidentate manner and, in general, all bond lengths for the uranyl(V) complex were longer than those for the uranyl(VI) complex. Additionally, a chemical shift was also observed in the U LI- and LIII-XANES spectra.]]></dc:description>

<dc:description><![CDATA[The lifetimes of excited states belonging to the lowest lying positive-parity bands in 106,108Cd have been measured using the Doppler-shift attenuation method. The resulting B(E2) transition rates show a significant decrease with increasing spin in 106Cd, whereas in 108Cd there is tentative evidence for a similar effect. The results are compared with cranking and semiclassical model calculations, which indicate that the structures have the properties expected from an "antimagnetic" rotational band resulting from the coupling of g9/2 proton holes to aligned pairs of h11/2 and g7/2 neutron particles.]]></dc:description>

<dc:source><![CDATA[Physics of Fluids 18(2006), 074105]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[The early stage of the turbulent flow driven by a rotating magnetic field is studied via direct numerical simulations and electric potential measurements for the case of a cyindrical geometry. The numerical results show that the undisturbed flow remains stable up to the linear stability limit, wheras small perturbations may initiate nonlinear transition at subcritical Taylor numbers. The observed instabilities occur randomly as isolated pairs of Taylor-Görtler vortices, which grow from spots to long tubes until they are dissipated in the lid boundary layers. At 7.5 times the critical Taylor number, the flow is governed by large-scale 3D fluctuations and may be characterized as weakly turbulent. Taylor-Görtler vortices provide the major turbulence mechanism, apart from oscillations of the rotation axis. As the vortices tend to align with the azimuthal direction, they result in a locally two-dimensional turbulence pattern.]]></dc:description>

<dc:source><![CDATA[Acta Materialia 54(2006)16, 4299-4306]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[SrTiO3(0 0 1)|LaAlO3(0 0 1) (STO|LAO) multilayers were investigated by density-functional band structure calculations. The lattice constant parallel to the interface equals roughly the average of the two constituents (3.81 Angstrom). The system contains two interface terminations: (I) SrO(0 0 1)|AlO2(0 0 1) with a spacing of 1.92 Angstrom as in STO and (II) TiO2(0 0 1)|LaO(0 0 1) with a spacing of 1.89 Angstrom as in LAO. 
Additional displacements of the metal atoms close to the boundaries lead to rumplings of up to 0.06 Angstrom. A stoichiometric model is electronically neutral and insulating. Model systems with only termination I exhibit spatially localised holes in the O-based valence band; in systems with termination II the additional electron occupies the Ti-based conduction band. The strongly anisotropic dielectric constants obtained from linear response calculations show that the interface chemistry allows a fine tuning of perovskite multilayers.]]></dc:description>

<dc:title><![CDATA[Reduction of surface coverage of finite systems due to geometrical steps]]></dc:title>
<dc:source><![CDATA[European Physical Journal B 62(2008), 311-317]]></dc:source>
<dc:date>2008</dc:date>
<dc:description><![CDATA[The coverage of vicinal, stepped surfaces with molecules is simulated with the help of a two-dimensional Ising model including local distortions and a Schwoebel barrie term at the steps. An effective two-spin model is capable to describe the main properties of this distorted Ising model. It is employed to analyze the behavior of the system close to the critical points. Within a well-defined regime of bonding strengths and Schwoebel barriers we find a reduction of coverage (magnetization) due to the presence of the surface step. This results in a second, low-temperature transition besides the standard Ising order-disorder transition. The additional transition is characterized by a divergence of the susceptibility and the magnetization as finite-size effects. Due to the surface step the specific heat diverges with a power law.]]></dc:description>

<dc:source><![CDATA[28th International Conference on the Physics of Semiconductors, 24.-28.07.2006, Wien, Austria]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Semiconductor superlattices represent a key model system for artificial crystals and are an essential component of novel infrared devices such as detectors and quantum cascade lasers. Hence their optical and transport properties have been investigated extensively during the past two decades. However, unlike for quantum well structures where considerable knowledge on the intersubband relaxation dynamics has been obtained, so far no experimental work has been published on the interminiband relaxation dynamics in superlattices. 

We have studied the transient transmission of a doped GaAs/Al0.3Ga0.7As superlattice in pump-probe experiments [1]. The superlattice with thickness of 9.0 nm and 2.5 nm of the wells and barriers, respectively, was n-doped in the center of the wells, resulting in a doping density of 1.51016 cm-3 averaged over one superlattice period. Picosecond infrared pulses in the range from 4 µm to 22 µm were generated at 13 MHz repetition rate by the free-electron laser FELBE at the Forschungszentrum Rossendorf. In particular, the experiments were performed at the absorption maxima of the superlattice at 9.0 µm and 15.8 µm. These wavelengths are the spectral positions of the van Hove singularities of the joint density of states in the center and at the edge of the mini-Brillouin zone, respectively.

The measured pump-probe signals consist of a fast component due to the bleaching of the interminiband transition and subsequent relaxation and thermalization, and a slower component due to cooling of the heated electron system. The fast component decays typically around 2-2.5 ps, in reasonable agreement with published theoretical values [2]. The slower component due to cooling is positive for excitation at 9.0 µm and negative at 15.8 µm and shows a strong temperature and excitation density dependence with cooling times ranging from 5 to 50 ps. This behavior is consistent with the temperature dependence of the linear absorption spectrum, i.e. yielding higher or lower transmission for increasing electron temperature. The effect provides an internal thermometer for the miniband electrons on a picosecond timescale. 

We will also report on data from superlattices with higher doping density, which shows the influence of electron-electron scattering.

Up to now, only <SUP>123</SUP>iodinated FA are available for myocardial viability diagnostics in some parts of the world, but the application is limited due to serious disadvantages: first, the expensive production of pure <SUP>123</SUP>I requires a cyclotron and second, the radiolabeled FA compounds must be purchased by outside vendors which resulted in disproportional costs and logistical problems. <SUP>99m</SUP>Tc, has ideal physical properties for SPECT-imaging (Eγ-= 140 keV), a short half- life of 6 h, and is available through a <SUP>99</SUP>Mo/<SUP>99m</SUP>Tc generator whenever needed. The development of <SUP>99m</SUP>Tc- labeled FA has been a goal of various research groups in the past. Despite many different approaches, no appropriate <SUP>99m</SUP>Tc compound with similar myocardial extraction properties as found with BMIPP and DMIPP is available to date. Most previous work in this field has focused on radiometal coordination by use of a polar tetradentate N<SUB>2</SUB>S<SUB>2</SUB> chelate with a central oxometal(V) core. We concentrated on the development and experimental evaluation of alternative coordination moieties according to the 4+1 mixed ligand approach to create newly technetium labeled FA with an improved myocardial profile. In the 4+1 donor atom arrangement, 99mTc is coordinated by both a tetradentae ligand and by a monodentate bearing the FA moiety. This system is rather lipophilic and show high stability towards, e.g. challenging SH-agents. While the conventional 4+1 <SUP>99m</SUP>Tc FA are built on in the sequence Tc-chelate, alkyl chain (a), carboxyl group (c) ->(Tc-a-c) we also developed and investigated some compounds with a new design according to the sequence carboxyl group (c), alkyl chain, Tc chelate, lipophilic tail (lt) -> (c  a  Tc  lt), transferring the <SUP>99m</SUP>Tc chelate from the end- to a more central position of the compound.]]></dc:description>

<dc:source><![CDATA[Journal of Materials Processing Technology 204(2008), 103-110]]></dc:source>
<dc:date>2008</dc:date>
<dc:description><![CDATA[This article presents experimental results of the extraction of metallic fibres from the surface of a melt pool. A low-melting alloy was used in a model facility to produce filaments of equal length. Operational parameters such as e.g. wheel speed and feed rate were varied to yield thin fibres. The analysis of the fibre cross-section showed, if ever, only a small decrease with increasing wheel speed. Highspeed video recording of the meniscus region was employed to investigate this falling short of expectation with respect to the commonly accepted tendencies. The recordings revealed that short fibres may only be produced during duty cycles. As available literature does not provide explanation of the observations, also a simple model was developed.]]></dc:description>

<dc:title><![CDATA[Uranium speciation of environmentally related waters]]></dc:title>
<dc:source><![CDATA[Western Pacific Geophysics Meeting, 27.07.2006, Beijing, China<br>Uranium speciation of environmentally related waters]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[In the environment uranium is one of the ubiquitous elements.  One million tons of uranium metal have been produced so far. Between 1945 and 1990 about one quarter of the total world production of uranium have been mined and milled in Eastern Germany. Especially these former intense uranium mining and milling activities have caused contaminations within urban areas. 


In the hexavalent oxidation state uranium is soluble in aqueous media. The determination of different species with non-invasive methods can be performed by Time-Resolved Laser-Induced Fluorescence Spectroscopy (TRLIFS) under natural conditions. This is due to the different fluorescence emission and fluorescence lifetime of the varying uranium species. 
The concentration of uranium ranges from the upper ng/L scale for table waters to the mg/L scale for mining related seepage and surface waters of the tailing ponds. From speciation calculations uranium in the most of these waters should be found as carbonate species. Unfortunately the carbonate species show poor fluorescence properties under ambient temperatures. By cooling of the samples to temperatures below 220 K an increase in the fluorescence intensity and lifetime can be observed. The dynamic quench effect of the carbonate ion decreases with decreasing temperature. Therefore the direct determination of the uranium speciation also in drinking waters can be performed. Examples of uranium carbonate speciation in a wide variety of natural waters will be given.


As an example, the dependence of the uranium speciation on pH of a tailing pond water was detected in detail by TRLIFS measurements. This water contains complexing anions like carbonate, phosphate, arsenate and sulphate. The uranium speciation in this surface water is strongly changed with pH. At pH 5 uranium arsenate species are dominating. The fluorescence emission of this species is in good agreement with data obtained from the uranium mineral troegerite.]]></dc:description>

<dc:description><![CDATA[Recently a new interest evolved in short time annealing far below 1 sec, i.e. the lower limit of Rapid Thermal Processing (RTP). This was driven by the need of suppressing the so-called Transient Enhanced Diffusion in advanced boron-implanted shallow pn-junctions. After a short common overview about the new opportunities in materials processing, in this talk two examples will serve for the demonstration of the new interest in flash lamp annealing (time duration < 20 msec) within the framework of semiconductor materials processing:  (i) For ultra-shallow junction formation in silicon Flash Lamp Processing (FLP) has become one of the challenging methods to meet the requirements for the next technology nodes defined by the ITRS roadmap. Low energy boron implants have been heat-treated in this way using peak temperatures in the range of 1100o to 1300oC and effective anneal times of 20 msec and 3 msec. Optimum processing conditions using a pulse time of 3 msec have been identified, under which one can obtain combinations of junction depth and sheet resistance values that meet even the 45 nm technology node requirements (ITRS 2001). (ii) The production of cubic SiC (3C-SiC) layers in device quality through the epitaxial growth on (100) Si wafers has remained a challenging task yet to overcome for selected applications the need in high cost bulk SiC wafers. It will be demonstrated that the use of Flash Lamp Processing (FLP) shows a new and promising way to the production of high quality 3C-layers. The FLASiC process bases on a new type of nanoscale liquid epitaxy at the interface SiC/Silicon leading to the formation of  SiC seed layers with low defect density on which thicker SiC layers were epigrown.]]></dc:description>

The multi-dot layer in the very thin gate oxide can be fabricated CMOS-compatibly by ion beam synthesis (IBS). Here, we present both experimental and theoretical studies on IBS of multi-dot layers consisting of Si nanocrystals (NCs). The NCs are produced by ultra low energy Si+ ion implantation, which causes a high Si supersaturation in the shallow implantation region. During post-implantation annealing, this su-persaturation leads to phase separation of the excess Si from the SiO2. Till now, the study of this phase separation suffered from the weak z contrast between Si and SiO2 phases in Transmission Electron Microscopy (TEM). Here, this imaging problem is solved by Energy Filtered Scanning Transmission Electron Microscopy (EFSTEM). Additionally, kinetic lattice Monte Carlo simula-tions of Si phase separation have been performed and compared with EFSTEM images. It has been predicted theoretically that the morphology of the multi-dot Si floating gate changes with increasing ion fluence from isolated, spherical NCs to percolated spinodal Si pattern. These pattern agree remarkably with EFSTEM images. However, the predicted fluence for spinodal pattern is lower than the experimental one. Because oxidants of the ambient atmosphere penetrate into the as-implanted SiO2, a substantial fraction of the implanted Si is lost due to oxidation.]]></dc:description>

<dc:description><![CDATA[Light emission from silicon has attracted considerable attention in the past few years due to the future potential in on-chip and inter-chip optical interconnects. This report reviews our current research work on efficient electroluminescence (EL) from silicon pn diodes and metal oxide semiconductor (MOS) devices. Efficient band edge EL with attractive power efficiencies up to 0.12 % has been observed in Si pn diodes prepared by boron implantation. We focus on the origin of the relatively high EL efficiency in Si pn diodes prepared by high-dose boron implantation, especially on the intriguing and anomalous increase of the EL for a temperature increase up to room temperature.  EL from rare earth doped metal oxide semiconductor (MOS) devices was also studied using ion implantation of different rare earth luminescent centers (Gd3+, Tb3+, Eu3+, Ce3+, Tm3+, Er3+) into the silicon dioxide layers with a transparent top electrode made of indium-tin oxide. Strong EL was obtained from different rare earth centers in UV to infrared. The electroluminescence properties were studied with respect to the luminescence spectra, decay time, impact excitation, cross relaxation (Tb3+), and efficiency. Top external quantum efficiency above 15 % was obtained, which is comparable to the InGaN quantum well light emitting diodes]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[We studied the effect of electric field generated on photoluminescence (PL) of silicon nanocrystals embedded in SiO2 films. We show that the application of electric field generated by means of surface acoustic waves (SAW) results in an increase of the PL intensity of nanocrystal photoluminescence by as much as 10% at a field amplitude of 12 kV/cm at temperatures below 15 K. At temperatures above 20 K the PL intensity decreases as the electric field is applied. The results are discussed within the frame of the self-trapped exciton model.]]></dc:description>

<dc:source><![CDATA[2nd Fabisch Symposium for Cancer Research and Molecular Cell Biology, 30.03.-01.04.2006, Berlin, Germany]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Peptide YY (PYY) is a 36 amino acid peptide amide that belongs to the PP-hormone family. It selectively binds to at least two G-protein coupled receptors named Y2- and Y5-receptor. These receptors are overexpressed in various tumors like neuroblastomas and nephroblastomas. With regard to clinical applications, NPY2 and NPY5 receptors may act as in vivo targets for receptor-directed therapy and diagnosis of the tumors, however there are specific and in vivo stabile ligands still required. The aim of the work was to synthesize receptor ligands, which could be radioloabeled with the positron emitting nuclides Ga-68 for small animal positron emission tomography (PET).
PYY derivatives were synthesized by solid-phase peptide synthesis, characterized by HPLC/MALDI techniques, purified by preparative HPLC and linked to DOTA (1,4,7,10-tetraazacyclotetradecane-N, N´,N´´,N´´´tetraacetic acid) as chelator for the <SUP>68</SUP>Ga(III). The in vitro binding affinity of the peptides was studied in SMS-KAN cells expressing NPY2 receptors by competitive receptor binding assays. Two Ga-68 labeled derivatives were studied in vivo by small animal PET in rats and mice. The activity was fast eliminated into the urine. One hour after injection was only in the kidneys remaining activity detected. 
Optimized Y2-selective and in vivo stabile peptides will be developed and tested for tumor targeting.]]></dc:description>

<dc:description><![CDATA[A new multipurpose thermalhydraulic test facility TOPFLOW (TwO Phase FLOW) was built and put into operation at Forschungszentrum Rossendorf in 2002 and 2003. Since then, it has been manly used for the investigation of generic and applied steady state and transient two phase flow phenomena and the development and validation of models of Computational Fluid Dynamic (CFD) codes in the frame of the German CFD initiative. The advantage of TOPFLOW consists in the combination of a large scale of the test channels with a wide operational range both of the flow velocities as well as of the system pressures and temperatures plus finally the availability of an special instrumentation that is capable in high spatial and temporal resolving two phase flow phenomena, for example the wire-mesh sensors.]]></dc:description>

<dc:description><![CDATA[The focus was on the investigation of U(IV) colloids during this phase of the project. First, a technique to reduce U(VI) to U(IV) was developed. Colloid formation and solubility of U(IV) in acidic HClO4/NaClO4 solutions were investigated by coulometric titration. Quantification of traces of U(VI) by laser fluorescence spectroscopy proved that the tetravalent state of uranium had been maintained. Laser-induced breakdown detection (LIBD) was applied for the detection of traces of uranium colloids as the pH was increased. The pH values at the onset of colloid formation were used for thermodynamic calculations aimed at determining the solubility products of crystalline and amorphous uranium dioxides. In acidic solutions, the UO2·xH2O(am) colloids showed colloidal stability over a period of at least 10 months during which they did not aggregate and precipitate. Relatively high zeta potentials were found for the UO2 colloids in the acidic and in the alkaline pH regions; the point of zero charge was at 6.9. No indications of the formation of mixed U(IV)-Al(III) complexes were found. There was also no influence of Al(III) on the UO2(cr) solubility.]]></dc:description>

<dc:description><![CDATA[The state-of-the-art interpretation of physical processes during post-implantation annealing, such as defect evolution and transient-enhanced boron diffusion assumes that ion implantation produces a supersaturation of single vacancies and self-interstitials. They are supposed to be mobile and may recombine or may form immobile clusters. On the other hand, atomistic simulations demonstrated that implantation may generate not only single vacancies and self-interstitials but also more complex defects. Furthermore, recent theoretical studies showed that small interstitial clusters may be mobile as well. The present work gives an overview on the latter investigations. Due to the complex structure of the interstitial clusters, methods based on the estimation of migration barriers by considering the potential energy surface at 0 K are hardly applicable. Molecular dynamics (MD) simulations must be used to get a thorough understanding of the migration mechanisms. Ab-initio MD simulations are presently not practicable since they require a tremendous computational effort.  Therefore atomic-level MD simulations are applied. The diffusivity of the small interstitial clusters, the self-diffusion coefficient per defect, and the corresponding effective migration barriers are determined. The implications of the present results for the explanation of experiments on post-implantation annealing and on room-temperature migration of implantation-induced self-interstitial defects are discussed.]]></dc:description>

<dc:description><![CDATA[Hydrogen interaction with defects in thin niobium (Nb) films was investigated using slow positron implantation spectroscopy (SPIS) combined with X-ray diffraction (XRD) and transmission electron microscopy (TEM). Thin Nb films on Si substrates were prepared using cathode beam sputtering at room temperature. Initially, the microstructure of the virgin (hydrogen-free) films was characterized. Subsequently, the films were step-by-step electrochemically charged with hydrogen and the evolution of the microstructure with increasing hydrogen concentration was monitored. Hydrogen loading leads to a significant lattice expansion which was measured by XRD. Contrary to free-standing bulk metals, thin films are highly anisotropic. The in-plane expansion is prevented because the films are clamped on the elastically hard substrate. On the other hand, the out-of-plane
expansion is substantially higher than in the bulk samples. Moreover, an enhanced hydrogen solubility in the a-phase was found in nanocrystalline Nb films. It was found that most of positrons in the films are trapped at open-volume defects at grain boundaries (GBs). These defects represent trapping sites also for hydrogen atoms. Hydrogen trapping at vacancy-like defects like GBs leads to a local increase of the electron density and is reflected by a pronounced decrease of the S parameter in the hydrogen-loaded samples. In addition, it was found that new defects are introduced at higher concentrations of hydrogen due to the formation of NbH (b-phase) particles.]]></dc:description>

<dc:description><![CDATA[Molecular recognition, binding and transport of different chemical species represents an aspect of supramolecular chemistry that has relevance to a number of areas that include biochemical processes, analytical techniques, recycling and environmental processes as well as aspects of catalysis and medicine. Over the years a large number of both efficient and selective receptors for cations, anions, salts and zwitterions based on different architectures and binding modes have been developed and studied. Among the manifold experimental techniques employed for the application of such receptors has been the investigation of the distribution of species between two immiscible solutions, normally an aqueous and an organic phase, under the influence of the receptor in the organic phase. Such a procedure has often allowed characterization of the receptors complexation behaviour towards individual species as well as enabling an evaluation of its suitability for species monitoring, separation and/or concentration; especially with respect to possible analytical applications as well as for use in extraction and membrane transport processes.]]></dc:description>

<dc:description><![CDATA[Recently it has been demonstrated that ion irradiation of nanostructures, interfaces and ultrathin magnetic films can modify substantially the nanocluster size distribution [1], the spatial nanocluster alignment [2], the nanocluster shape [3] and the chemical order of metal alloys [4]. Furthermore, low-energy ion-erosion of semiconductor [5] and metal [6] surfaces can result in the formation and self-organization of nanostructures.
For all phenomena listed above (disregarding chemical ordering), ion-irradiation-activated interface/surface processes have been identified as the driving force. Thus, a fundamental understanding of the basic mechanisms of the interface/surface evolution under ion-irradiation might allow a controlled growth and a taming of properties of nanostructures. 
This contribution will review theoretical studies and atomistic computer simulations which demonstrate that the above listed phenomena have the same origin: a competition of surface erosion or interface mixing on the one hand and diffusional processes on the other. The far-from-equilibrium processing of nanostructures can lead to exotic properties like negative interface energy and inverse Ostwald ripening.

<dc:description><![CDATA[A Pt/C multilayer stack (15 layer-pairs) with Fe impurities was prepared on a glass substrate by the ion sputtering technique. Ion irradiation effects on this multilayer were studied following irradiation with 2 MeV Au ions at fluences from 1 · 1014 to 1 · 1015 ions/ cm2. Irradiation induced atomic displacements in such multilayers have been earlier analyzed by a combined X-ray standing wave (XSW) and X-ray reflectivity (XRR) technique with a depth resolution better than 0.2 nm [S.K. Ghose, B.N. Dev, Phys. Rev. B 63 (2001) 245409; S.K. Ghose, D.K. Goswami, B. Rout, B.N. Dev, G. Kuri, G. Materlik, Appl. Phys. Lett. 79 (2001) 467]. Using the combined XSW-XRR technique ion beam induced preferential movement of Fe from C- to Pt-layers has been detected. At the highest ion fluence Pt layers (containing Fe) break into nanoparticles apparently surrounded by C. Grazing incidence X-ray diffraction (GIXRD) measurements indicate the formation of FePt particles in the irradiated multilayer samples. Results of magnetic force microscopy (MFM) and magneto-optical Kerr effect (MOKE) measurements reveal that while the virgin sample hardly shows any magnetism, the irradiated samples show a soft ferromagnetism with an increasing coercive field with increasing ion fluence. Use of focused ion beam to fabricate ferromagnetic nanodots and their possible uses in spin electronics are discussed.]]></dc:description>

<dc:source><![CDATA[21st General Conference of the EPS Condensed Matter Division, 27.-31.03.2006, Dresden, Deutschland]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Recently ion irradiation has been proposed as a patterning tool for different magnetic systems. The increasing interest for this technique is due to the capability of tailoring the magnetic properties without affecting the sample topography. We present a study of the magnetic properties of patterns with different geometries produced by ion irradiatio on a Ni81Fe19/Fe50Mn50 exchange bias bilayer by magneto-optic Kerr effect (MOKE) magnetometry and magnetic force microscopy (MFM). The hysteresis loops measured by MOKE present features evidently related to the irradiated geometries. Moreover they also reveal that the magnetization reversal is not proceeding independently in irradiated and non-irradiated areas. This magnetic coupling is confirmed by MFM images, which clearly show that magnetic domains in irradiated and non-irradiated elements are mutually influencing each other during the reversal process. Comparison with previous studies indicates that the above mentioned coupling dramatically affects the reversal process only when the lateral size of irradiated elements approaches a characteristic coupling length.]]></dc:description>

<dc:description><![CDATA[Since irradiation affects in-service properties of zirconia, we investigated the fluence dependence on production and thermal stability of defects induced by helium and oxygen-ion implantation in single crystals of yttria-fully-stabilized zirconia. In either case, depth profiling by slow positron implantation spectroscopy (SPIS) detects a distribution of vacancy-type defects peaking at 60% of the projected ion range Rp. Owing to the saturation of positron-trapping occurring for low fluences, which depends on the ion mass, we could estimate a critical size of clusters ranging from 0.4 to 1.6 nm. The lack of SPIS-evidence of an open-volume excess at Rp is explained by the presence of over-pressurized gas bubbles. This assumption is confirmed by Nuclear Reaction Analysis of 3He concentration profiles, which shows that helium remains partly trapped at Rp, even after annealing above 400 °C.]]></dc:description>

<dc:description><![CDATA[Functionalisation of an L-RNA oligonucleotide with 1,4,7,10-tetraazacyclododecane-N,N',N'',N'''-tetraacetic acid (DOTA) was performed using the N-succinimide ester 2. The DOTA-functionalised L-RNA oligonucleotide 3 was radiolabelled with the positron-emitting radiometals <SUP>86</SUP>Y(III) and <SUP>68</SUP>Ga(III) in radiochemical yields of 76 % and 93 %, respectively. Compound 4a represents the first example of an oligonucleotide labelled with the positron emitter <SUP>86</SUP>Y. Biodistribution studies of the <SUP>86</SUP>Y-radiolabelled L-RNA oligonucleotide 4a were performed in Wistar rats showing higher levels of radioactivity in the adrenal glands and kidneys. The low bone uptake (0.19 %ID/g after 60 min) is indicative of the high kinetic stability of the <SUP>86</SUP>Y-DOTA chelate in vivo.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[The coherent interaction of femtosecond laser pulses in the pumpprobe regime has been experimentally studied in the time domain by monitoring light reflection from a tellurium single crystal. The optical response of the probed medium exhibits periodic variations at a frequency equal to that of the exciting laser radiation. Experimental dependences of the observed "coherent artifact" on the pump/probe intensity ratio, the number of accumulated pulses, and the mutual orientation of the polarization vectors of electromagnetic fields and the crystallographic axes are well described by the proposed phenomenological model.]]></dc:description>

<dc:source><![CDATA[The Seventeenth International Workshop on Operator Theory and Applications (IWOTA 2006), 31.07.-03.08.2006, Seoul, South Korea]]></dc:source>

<dc:description><![CDATA[PT-symmetric Quantum Mechanics, the Squire equation of hydrodynamics and the spherically symmetric α²-dynamo of magnetohydrodynamics (MHD) can be structurally linked and treated in a unified way as spectral problems in Krein spaces. We demonstrate their interrelation explicitly and provide examples for specific parameter dependencies of their spectra. Special emphasis is laid on the physical relevance of transitions between real and complex spectral branches in connection with phase transitions between sectors of exact PT-symmetry and spontaneously broken PT-symmetry in Quantum Mechanics as well as with possible polarity reversals of dynamo maintained magnetic fields of planets. We briefly comment on third order spectral branch points with geometric multiplicity one and algebraic multiplicity three as well as on a dynamo related resonant unfolding of diabolical points (spectral intersection points of geometric and algebraic multiplicity two).

<dc:description><![CDATA[The morphology of polymer macroparticles is directly linked to the various parameters of the polymerisation process. X-ray cone beam microtomography is a tool to provide key information on internal structure like morphology, porosity and interfacial area of such particles to the process engineers. By further application of image processing tools to the reconstructed tomograms, we were able to identify different characteristic morphologies within different polyolefin samples and to detect enclosed voids, which will ultimately not contribute to the active surface area.]]></dc:description>

<dc:description><![CDATA[Dipole-strength distributions in the nuclides 92$Mo, 98Mo and 100Mo have been investigated in photon-scattering experiments at the superconducting electron accelerator ELBE of the Forschungszentrum Rossendorf. 
A simulation of gamma cascades was performed in order to estimate the distribution of inelastic transitions to low-lying states and thus to deduce the correct dipole-strength distributions up to the neutron-separation energies. The obtained absorption cross sections connect smoothly to (gamma,n) cross sections and give novel information about the low-energy tail of the Giant Dipole Resonance below the neutron-separation energies. The experimental cross sections are compared with predictions of a Quasiparticle-Random-Phase Approximation in a deformed basis.

Photoactivation experiments were performed at various electron energies to study the 92Mo(gamma,n), 92Mo(gamma,p) and 92Mo(gamma,alpha) reactions. The deduced activation yields are compared with theoretical predictions.]]></dc:description>

<dc:source><![CDATA[Materials Science Forum 483-487(2005), 233]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[An approach for the defect density reduction in 3C-SiC epitaxially grown on Si is to improve the quality of the carbonized layer during the early stage of growth. For this reason the conventional carbonization process was replaced by a slower and nearer equilibrium carbonization method. Carbon is introduced by implantation  into oxide of an ocidized Si substrate, near the SiO2/Si interface, and then it is transferred to the Si surface by annealing. Good quality 3C-SiC grains are formed embedded into the Si substrate, which are absolutely flat at the SiO2/Si interface. Another advantage of the new carbonization process is the elimination of the cavities due to the suppression of Si out-diffusion.]]></dc:description>

<dc:description><![CDATA[Halbleitermaterialien, insbesondere Silizium, erfordern nach bestimmten Prozessschritten wie der strahlenschädigenden Ionenimplantations-Dotierung eine Temperbehandlung, deren Zeitdauer im Verlauf der letzten Jahre im Extremfall nur noch ca. 1 sec betrug. Solche kurzen Temperzeiten erfordern Anlagen, bei denen die Oberflächen durch Lichteinstrahlung bewirkt werden kann, um schnelle Zykluszeiten und eine geringe Aufheizung der Probenumgebung zu gewährleisten. Kürzlich wurden diese Anforderungen noch verschärft, indem die Forderung nach Temperzeiten im msec-Bereich erhoben wurde. Während Temperzeiten bis hinab zu einer Sekunde noch mit relativ langsam reagierenden Halogenlampen gewährleistet werden können, sind kürzere Temperzeiten nur noch mit schnell schaltbaren Xenon-Blitzlampen oder gerasterten Laserstrahlen realisierbar. Der Vorteil solch einer extrem kurzen Oberflächen-Wärmebehandlung liegt vor allem darin, dass das Volumen der Probe nicht mehr unbedingt durchgeheizt wird, andererseits aber auch ein gezieltes Anschmelzen von Oberflächen möglich wird.  Ebenso sind mit solchen Techniken extrem kurze Zykluszeiten in Produktionsabläufen realisierbar. Im Vortrag werden Fragen der Anlagentechnik sowie Anwendungsbeispiele aus der fortgeschrittenen Halbleitertechnologie behandelt: a) Unterdrückung der beschleunigten Diffusion von Bor-Implantaten, sowie b) Unterstützung der Heteroepitaxie von Siliziumkarbid auf Silizium durch nanoskalige  Phasenverflüssigung an der Grenzfläche. Es wird ein kurzer Ausblick zu Anwendungen ausserhalb der Welt der Halbleiter gegeben.]]></dc:description>

<dc:source><![CDATA[Journal of Alloys and Compounds 401(2005), 226-230]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Recently it has been shown that lateral carrier confinement in an InGaAs quantum well (QW) embedded in GaAs can be achieved by using a laterally patterned InGaP stressor layer on top of the heterostructure. To exploit this effect in a device the structure has to be planarized by a second epitaxial step. It has been shown that the lateral strain modulation almost vanishes after overgrowth with GaAs, whereas overgrowth with a single ternary layer of opposite strain compared to the stressor layer suffers from strain induced decomposition. Here we show that the lateral carrier confinement of the initially free standing nanostructure can almost be maintained using a two step process for overgrowth, where a strained thin ternary layer is grown first followed by GaAs up to complete planarization of the patterned structure. Thickness and composition of the ternary layer are adjusted on the basis of finite element calculations of the strain distribution (FEM). The strain field achieved after overgrowth is probed by X-ray grazing-incidence diffraction (GID).]]></dc:description>

<dc:date>2004</dc:date>
<dc:description><![CDATA[Kinetic Lattice Monte Carlo (KLMC) simulations can predict reaction pathways for the ion-beam-assisted fabrication of  functional nanostructures. Three examples will be presented, which are based on different kinds of ion-solid-interaction: (i) High-dose ion implantation of species which are immiscible within the surface layer produces a far-from-equilibrium state. A post-implantation thermal treatment activates phase separation. According to predictive simulations the location and size of the nanoclusters can be controlled by boundary conditions (i.e. interfaces) and annealing parameters. (ii)Ion irradiation through an interface between immiscible phases leads to a thin interface film of an unstable alloy which is formed by collisional mixing. KLMC simulations of phase separation in this film predicts a self-organised/self-aligned nanocluster formation . (iii) Ion irradiation can produce chemical order in intermetallic alloys at low temperature. KLMC simulations show that chemical ordering requires mobile vacancies. Without irradiation the formation of vacancies requires high temperatures at which the ordered phase might be unstable. Thus, thermally activated ordering of some intermetallics like Heusler alloys is difficult, whereas ion irradiation orders them. 
Process simulations of phase separation in Si implanted gate oxides and at ion irradiated Si/SiO2 interfaces have been performed in the framework of an European GROWTH, where a novel non-volatile memory transistor was developed.  Irradiation-induced ordering studies are focussed on future magnetic recording materials (FePt) and materials for spintronics.]]></dc:description>

<dc:source><![CDATA[Physical Review B 74(2006), 045209-1]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Measurements of (110) planar channeling radiation have been performed at the radiation source ELBE at electron energies of 14.6, 17, 30 and 34 MeV using diamond crystals of thickness 42.5, 102, 168 and 500 micrometers. The influence of different line-broadening mechanisms on the spectral shape of radiation from the 1 - 0 transition has been investigated. The analysis bases on fitting a convolution of the intrinsic Lorentz-like line shape with a Gaussian-like multiple-scattering distribution to the measured spectra. The asymmetry parameter involved relates to the standard deviation of the multiple-scattering angle under channeling condition. Its dependence on the crystal thickness at channeling was found to be weaker than for nonchanneled particles. The deduced coherence lengths show no significant dependence on the electron energy.]]></dc:description>

<dc:description><![CDATA[The mechanism behind energetic ion impact induced stress reduction in highly stressed tetrahedral amorphous carbon and cubic boron nitride thin films is investigated by real time in situ spectroscopic ellipsometry and ex situ electron microscopy. Highly stressed carbon and boron nitride films were grown by filtered cathodic vacuum arc and RF magnetron sputtering, respectively. The films were then implanted by 510 keV argon ions and the film optical properties and thickness monitored in situ by spectroscopic ellipsometry. In both cases the films were observed to expand due to a reduction in the density of the ion-modified layer. Cross-sectional transmission electron microscopy and electron energy loss spectroscopy of the carbon films showed that this reduction in density is associated with a conversion of diamond-like bonding to graphite-like bonding. In situ stress measurements performed on the boron nitride films revealed a simultaneous reduction in stress with expansion of the material.]]></dc:description>

<dc:source><![CDATA[Eleventh Marcel Grossmann Meeting on recent developments in theoretical and experimental general relativity, gravitation and relativistic field theories., 23.-29.07.2006, Berlin, Germany]]></dc:source>

<dc:description><![CDATA[Subject of the talk is a multidimensional gravitational model with scalar curvature nonlinearity R<SUP>4</SUP>. It is assumed that the higher dimensional spacetime manifold of this model undergoes a spontaneous compactification to a manifold with warped product structure. The main attention is paid to the stability of the extra-dimensional factor spaces and it is shown that for certain parameter regions the system allows for a freezing stabilization of these spaces. The most interesting fact, which is demonstrated, is a dependence of the stability region (in parameter space) on the total dimension D=dim(M) of the higher dimensional spacetime M. For D>8 the stability region consists of a single (absolutely stable) sector which is shielded from a conformal singularity (and an antigravity sector beyond it) by a potential barrier of infinite height and width. This sector is smoothly connected with the stability region of a curvature-linear model. For D<8 an additional (metastable) sector exists which is separated from the conformal singularity by a potential barrier of finite height and width so that systems in this sector are prone to collapse into the conformal singularity. This second sector is not smoothly connected with the first (absolutely stable) one. Several limiting cases and the possibility for inflation are discussed. The talk is mainly based on:

<dc:date>2007</dc:date>
<dc:description><![CDATA[The introduction of oxygen during the SiO-VLS growth of silicon nanowires causes a shift in SiOx stoichiometry resulting in an increased formation of SiO2 at the nanowire surface. This leads to instabilities of the usual cylindrical nanowire core-shell structure, where the liquid Au/Si alloy droplet at the nanowire tip is incorporated inside a SiO2 nanowire in form of a periodic array of nanoparticles. The structure and the composition of the resulting nanostructure are investigated in detail using high-resolution and analytical transmission electron microscopy. The influence of the oxygen is investigated experimentally and supports our model of the formation mechanism.]]></dc:description>

<dc:description><![CDATA[A nano-sized amorphous layer embedded in an atomic simulation cell was used to study the amorphous-to-crystalline (a-c) transition and subsequent phase transformation by molecular-dynamics computer simulations in 3CSiC. The recovery of bond defects at the interfaces is an important process driving the initial epitaxial recrystallization of the amorphous layer, which is hindered by the nucleation of a polycrystalline 2HSiC phase. The kink sites and triple junctions formed at the interfaces between 2H and 3CSiC provide low-energy paths for 2HSiC atoms to transform to 3CSiC atoms. The spectrum of activation energies associated with these processes ranges from below 0.8 eV to about 1.9 eV.]]></dc:description>

<dc:source><![CDATA[Nuclear Engineering and Design 237(2007), 1608-1617]]></dc:source>
<dc:date>2007</dc:date>
<dc:description><![CDATA[An application of wire-mesh sensors to obtain the interfacial area concentration in vertical pipes is presented as an alternative to widely used multiple-tip electrical or optical fibre probes. The measuring data of a mesh sensor consists in a three-dimensional matrix of local instantaneous gas fractions measured at each crossing point of the wires and recorded as a time sequence. Bubbles are clearly reflected in this data matrix, since they represent regions of interconnected elements containing the gaseous phase. The method to deduce the interfacial area concentration from this data is based on a full reconstruction of the gas-liquid interface, where the interfacial area of each bubble is recovered as the sum of the surface area of all surface elements belonging to the given bubble. The new method can be applied to large bubbles with an arbitrary shape. To study the change of the interfacial area concentration along the pipe the distance between sensor and gas injection was varied. Obtained results were compared to the findings reported in literature.]]></dc:description>

<dc:title><![CDATA[Picosecond dynamics of interminiband transitions in doped GaAs/AlGaAs superlattices]]></dc:title>
<dc:source><![CDATA[POISE Summer School, 25.-30.06.2006, Cortona, Italia]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Semiconductor superlattices are an essential component of novel infrared devices such as detectors and quantum cascade lasers and their optical and transport properties have been investigated extensively during the past two decades. However, unlike for quantum well structures where considerable knowledge on the intersubband relaxation dynamics has been obtained, so far no experimental work has been published on the interminiband relaxation dynamics in superlattices. 

In this work we have studied the transient transmission of a doped GaAs/Al0.3Ga0.7As superlattice in pump-probe experiments [1]. The superlattice with thickness of 9.0 nm and 2.5 nm of the wells and barriers, respectively, was n-doped in the center of the wells, resulting in a doping density of 1.51016 cm-3 averaged over one superlattice period. Picosecond infrared pulses with energies up to 100 nJ in the range from 4 µm to 22 µm were generated at 13 MHz repetition rate by the free-electron laser FELBE at the Forschungszentrum Rossendorf. In particular, the experiments were performed at the absorption maxima of the superlattice at 9.0 µm and 15.8 µm (compare Fig. 1). These wavelengths are the spectral positions of the van Hove singularities of the joint density of states in the center and at the edge of the mini-Brillouin zone, respectively.

The measured pump-probe signals shown in Fig 2 consist of a fast component due to the bleaching of the interminiband transition and subsequent relaxation and thermalization, and a slower component due to cooling of the heated electron system. The fast component decays typically around 2-2.5 ps, in reasonable agreement with published theoretical values [2]. The slower component due to cooling is positive for excitation at 9.0 µm and negative at 15.8 µm and shows a strong temperature and excitation density dependence with cooling times ranging from 5 to 50 ps. This behavior is consistent with the temperature dependence of the linear absorption spectrum, i.e. yielding higher or lower transmission for increasing electron temperature. The effect provides an internal thermometer for the miniband electrons on a picosecond timescale.

<dc:title><![CDATA[Experimentelle Hypoxie induziert eine erhöhte Radiotracer-Aufnahme in primären Endothelzellen in vitro]]></dc:title>
<dc:source><![CDATA[Nuklearmedizin 45(2006)2, A79]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Ziel/Aim:
Die Radiotracer-Aufnahme von hypoxischen Arealen in solidem Tumorgewebe ist ein wichtiger Parameter für die Visualisierung von Tumoren mit PET. Das Ziel des vorgestellten Projekts ist die Bewertung von Endothelzellen hinsichtlich ihrer Radiotraceraufnahme unter hypoxischen Bedingungen.

Methodik/Methods:
Verschiedene humane primäre Endothelzellen aus der Nabelschnurvene (HUVEC), der Aorta (HAEC) und der Haut (HDMEC) wurden neben etablierten Tumorzelllinien FaDu und HT-29 verwendet. Experimentelle Hypoxie wurde mit einem speziellen Inkubator (Gasboy, Labotect, Göttingen) erzeugt. Nach 24h Kultivierung unter hypoxischen Bedingungen wurde die Expression der Gene HIF-1#alpha# und VEGF mit PCR analysiert sowie die Aufnahme der Radiotracer [Tc-99m]Sestamibi und [F-18]FDG gemessen.

Ergebnisse/Results:
Unter experimenteller Hypoxie wurde eine verstärkte Expression von HIF-1#alpha# sowie VEGF gemessen. Die Aufnahme von [Tc-99m]Sestamibi, einem Marker für die Intaktheit der Atmungskette, war in allen Zelltypen unter hypoxischen Bedingungen verringert. Die [F-18]FDG Aufnahme unter hypoxischen Bedingungen war sowohl von den verwendeten primären Endothelzellen als auch von Tumorzellen deutlich erhöht.

Schlussfolgerungen/Conclusions:
Primäre Endothelzellen nehmen wie Tumorzellen in Gegenwart von experimentell erzeugter Hypoxie vermehrt den Radiotracer [F-18]FDG auf. In vaskularisierten soliden Tumoren tragen Endothelzellen somit zur Anreicherung von Radiotracern bei und haben einen Einfluss auf die nachfolgende Bildgebung mit PET.]]></dc:description>

<dc:description><![CDATA[Experimental and numerical investigations of artificial water hammers in a pipe with a bend are presented. At FZR a cold water hammer test facility was used to measure the fluid pressures and the pipe wall stresses occurring during water hammers. The  finite element code ANSYS® was used for the numerical analysis of the experiments. The focus was put on the local distributions of pressure and stress. It could be shown that the fluid pressure and pipe wall stress exhibit complex 3-dimensional structures, which is a consequence of the fluid-structure interaction. The highest stresses occur in the pipe bend. The pressure peak is lower than predicted by the extended Joukowsky formula.]]></dc:description>

<dc:description><![CDATA[Art objects made of glass may undergo deterioration when exposed to environmental stress. Even in air conditioned museums, susceptible glass surfaces may decompose. Thus, their transparency is reduced and initial tiny surface cracks may result in irreplaceable loss of glass. Degradation takes place via ion exchange reactions between the silicate network and the humidity of the ambient atmosphere. Endangered glass objects in important collections should be studied using non-destructive analytical methods. In this regard, the advantage of ion beam analysis by simultaneous Particle Induced Gamma-ray Emission (PIGE), Particle Induced X-ray Emission (PIXE) and Rutherford Backscattering Spectrometry (RBS) in a non-vacuum facility is demonstrated. This paper is concerned with both the current condition of the glass surface and the composition of the bulk of the glass. The result of such ion beam examination enables the scientist to recommend suitable storage conditions. In addition, the non-destructive study provides scientists studying art objects with means of objective material identification, enabling them to reach conclusions with respect to particular glass technologies or proveniences.]]></dc:description>

<dc:description><![CDATA[In diesem Vortrag sollte dargestellt werden, mit welchen Methoden sich die Astrophysik Information über den Kosmos beschafft und welche Vor- und Nachteile erdgebundene gegenüber weltraumgestützten Beobachtungen haben. Dabei wurde insbesondere auf den Nachweis elektromagnetischer Strahlung und kosmischer Teilchen eingegangen.
Ein Teil des elektromagnetischen Spektrums wird durch die Erdatmosphäre absorbiert und geladene Teilchen werden bis zu einer bestimmten Energie durch das Erdmagnetfeld abgelenkt. Hochenergetische Teilchen können jedoch in der Atmosphäre Teilchenschauer auslösen, die mit verschiedenen Detektortypen am Erdboden nachgewiesen werden können, wobei unterschiedliche physikalische Prozesse ausgenutzt werden. Als Beispiele wurde die Funktionsweise von Radioantennen, CCD-Kameras (Charge-Coupled Device), des Chandra-Röntgenteleskops und EGRET (Energetic Gamma Ray Experiment Telescope) für den Nachweis elektromagnetischer Strahlung, sowie des AMS-Experimentes (Alpha Magnetic Spectrometer) mit seinen vielfältigen Detektortypen zum Nachweis kosmischer Teilchen vorgestellt.
Ohne die Resultate dieser Messungen wäre die Entwicklung kosmolgischer Modelle nicht möglich. Gleichzeitg werden dadurch neue Fragen aufgeworfen, die Anstoß zur Verbesserung und Entwicklung neuer Detektortypen liefern.]]></dc:description>

<dc:description><![CDATA[Mixing phenomena observed when the flow rate in a single loop of the primary circuit is changed can influence the operation of Pressurized Water Reactor (PWR) by inducing local gradients of boron concentration or coolant temperature.  Analysis of one-dimensional Laser Doppler Anemometry measurements during the start-up and shutdown of pump on a single loop of the ROCOM test facility has been performed.  The effect of a step change and a ramped change in the flow rate on the axial and azimuthal velocities was examined.  Numerical simulations were also performed for the step change in the flow rate that gave quantitative agreement with the axial velocities.  Phenomenological agreement was made on the turbulent kinetic energy; however, observed values were a factor of 10 less than the turbulent kinetic energy derived from the measurements.]]></dc:description>

<dc:source><![CDATA[Physical Review C 72(2005), 031301]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[Superdeformation and hyperdeformation in 108Cd have been studied for the first time within the framework of the fully self-consistent cranked mean-field theory, namely, cranked relativistic mean-field theory. The structure of observed superdeformed bands 1 and 2 have been analyzed in detail. The bumps seen in their dynamic moments of inertia are explained as arising from unpaired band crossings. This is contrary to an explanation given earlier within the framework of the projected shell model. It was also concluded that this nucleus is not a doubly magic superdeformed nucleus.]]></dc:description>

<dc:description><![CDATA[Thin polypropylene fibers have been used for internal experiments in storage rings as an option for hydrogen targets. The change of the hydrogen content due to the radiation dose applied by the circulating proton beam has been investigated in the range 1 × 1062 × 108 Gy at beam momenta of 1.53 GeV/c by comparing the elastic pp-scattering yield to that from inelastic p-carbon reactions. It is found that the loss of hydrogen as a function of applied dose receives contributions from a fast and a slow component.]]></dc:description>

<dc:source><![CDATA[Tag des offenen Labors, 20.05.2006, Dresden, Germany]]></dc:source>
<dc:date>2006</dc:date>
<dc:description><![CDATA[Bakterien waren die ersten Lebewesen auf unserem Planeten. Über die Jahrmilliarden haben sie gelernt, sich an jeden noch so unwirtlichen Lebensraum anzupassen und nahezu jede noch so komplexe chemische Verbindung abzubauen. Fälschlicherweise haben sie sich insbesondere als Krankheitserreger einen Namen gemacht. Bei genauerer Beschäftigung mit diesen kleinsten Lebewesen wird nämlich schnell klar, dass es sich dabei nur um Ausnahmeerscheinungen handelt. Nach vorsichtigen Schätzungen kennt man zwar nur etwa 1 % aller Bakterien, aber es ist unumstritten, dass nur durch ihre Aktivität das Leben in seiner heutigen Form möglich geworden ist. Neben ihrem fundamentalen Beitrag zur Entstehung der heutigen Atmosphäre und damit der Grundlage unseren Lebens, sorgen sie außerdem dafür, dass die Kreisläufe der Natur nicht zum Erliegen kommen.
Der Vortrag soll dazu einen Überblick geben und am Beispiel ungewöhnlicher Leistungen sowie besonderer Eigenschaften der Bakterien deren Anwendungspotential vor dem Hintergrund der Arbeiten am Forschungszentrum Rossendorf aufzeigen.]]></dc:description>

<dc:description><![CDATA[Positrons may be used in many cases to determine defect densities of vacancies and dislocations. In case of saturated positron trapping, i.e. all positrons are getting trapped, only a lower-limit estimation can be given. However, a combination of positron back-diffusion measurements using a monoenergetic positron beam in combination with conventional lifetime spectroscopy can be used to overcome the problem of saturated positron trapping. As a case study, this combination was used for the determination of dislocation densities in polycrystalline nickel samples of highly varying dislocation density. Saturated positron trapping into dislocations and small voids was observed. The total positron trapping rate was calculated from the positron diffusion length obtained by back-diffusion experiments. The trapping rates of the two defects were finally obtained using the decomposition of lifetime spectra. The results were found in good agreement with those determined by the analysis of synchrotron Bragg-diffraction profiles, measured on the same set of samples. From the comparison of both techniques, the positron trapping coefficient was found to be ldisl = 3.9 ± 0.3 cm2/s for a high density of dislocations in Ni.]]></dc:description>

<dc:description><![CDATA[Considering the late in-vessel phase of an unlikely core melt down scenario in a light water reactor (LWR) with the formation of a corium pool in the lower head of the re-actor pressure vessel (RPV) the possible failure modes of the RPV and the time to failure have to be investigated to assess the possible loadings on the containment. In this work, an integral model was developed to describe the processes in the lower plenum of the RPV. Two principal model domains have to be distinguished: The temperature field within the melt and RPV is calculated with a thermodynamic model, while a mechanical model is used for the structural analysis of the vessel wall.
In the introducing chapters a description is given of the considered accident scenario and the relevant analytical, experimental, and numerical investigations are discussed which were performed worldwide during the last three decades. Following, the occur-ring physical phenomena are analysed and the scaling differences are evaluated between the FOREVER-experiments and a prototypical scenario.
The thermodynamic and the mechanical model can be coupled recursively to take into account the mutual influence. This approach not only allows to consider the tem-perature dependence of the material parameters and the thermally induced stress in the mechanical model, it also takes into account the response of the temperature field itself upon the changing vessel geometry.
New approaches are applied in this work for the simulation of creep and damage. Using a creep data base, the application of single creep laws could be avoided which is especially advantageous if large temperature, stress, and strain ranges have to be covered. Based on experimental investigations, the creep data base has been de-veloped for an RPV-steel and has been validated against creep tests with different scalings and geometries.
It can be stated, that the coupled model is able to exactly describe and predict the vessel deformation in the scaled integral FOREVER-tests. There are uncertainties concerning the time to failure which are related to inexactly known material parame-ters and boundary conditions.
The main results of this work can be summarised as follows: Due to the thermody-namic behaviour of the large melt pool with internal heat sources, the upper third of the lower RPV head is exposed to the highest thermo-mechanical loads. This region is called hot focus. Contrary to that, the pole part of the lower head has a higher strength and therefore relocates almost vertically downwards under the combined thermal, weight and internal pressure load of the RPV. 
On the one hand, it will be possible by external flooding to retain the corium within the RPV even at increased pressures and even in reactors with high power (as e.g. KONVOI). On the other hand, there is no chance for melt retention in the considered scenario if neither internal nor external flooding of the RPV can be achieved.
Two patents have been derived from the gained insights. Both are related to pas-sively working devices for accident mitigation: The first one is a support of the RPV lower head pole part. It reduces the maximum mechanical load in the highly stressed area of the hot focus. In this way, it can prevent failure or at least extend the time to failure of the vessel. The second device implements a passive accident mitigation measure by making use of the downward movement of the lower head. Through this, a valve or a flap can be opened to flood the reactor pit with water from a storage res-ervoir located at a higher position in the reactor building.
With regard to future plant designs it can be stated - differing from former presump-tions - that an In-Vessel-Retention (IVR) of a molten core is possible within the reac-tor pressure vessel even for reactors with higher power.]]></dc:description>

<dc:date>2005</dc:date>
<dc:description><![CDATA[In the present work, positron annihilation spectroscopy (PAS) is employed for microstructure investigations of various ultra fine grained (UFG) metals (Cu, Ni, Fe) prepared by severe plastic deformation (SPD), namely high-pressure torsion (HPT) and equal channel angular pressing (ECAP): Generally, UFG metals prepared using both the techniques exhibit two kinds of defects introduced by SPD: dislocations and small microvoids. The size of the microvoids is determined from the PAS data. Significantly larger microvoids are found in HPT deformed Fe and Ni compared to HPT deformed Cu. The microstructure of UFG Cu prepared by HPT and ECAP is compared and the spatial distribution of defects in UFG Cu samples is characterized. In addition, the mircrostructure of a pure UFG Cu prepared by HPT and HPT deformed Cu+Al2O3 nanocomposite (GlidCop) is compared.]]></dc:description>

<dc:source><![CDATA[DPG Annual Meeting 2005, 04.-09.03.2005, Berlin, Germany]]></dc:source>
<dc:date>2005</dc:date>
<dc:description><![CDATA[In recent years, immense effort has been devoted to the synthesis of Si nanocrystals (NCs) for multi-dot floating-gate MOSFETs. To assure optimum memory device characteristics, the Si NCs should be equal in size and equally distant from the transistor channel. This desired Si NCs structure can be fabricated in a two-step process of ion irradiation through a SiO2-Si interface and subsequent annealing [1,2]. Previously, the Si NCs could not directly been studied with XTEM because of the low mass contrast of Si NCs to SiO2 and their very small size of less than 3nm.
In this XTEM study we prove the validity of the Si NC formation process. For a mass contrast enhancement of the Si NCs we used Ge to decorate them: A thin Ge layer was embedded into the oxide. During annealing, diffusing Ge is captured by the Si NCs due to the favourable Si-Ge bond. Thereby, the Si NCs are alloyed resulting in Si1−xGex NCs which are equally aligned with the SiO2-Si interface in a tunnel distance of about 3nm. These structural results are in line with the eletronic device characteristics which are dicussed in the contributions of Heinig and Schmidt in this symposium.]]></dc:description>

<dc:description><![CDATA[Sigma receptors are membrane-bound proteins having high affinities for a variety psychotropic
drugs with opiate-type structures. The sigma receptor subtypes, sigma-1 and sigma-2, have different molecular weights and pharmacological roles.1 Many cancer cell lines (breast, melanoma, prostate cancer) express high levels of sigma receptors,2,3 and proliferative tumor cells express much higher levels of sigma-2 receptors than quiescent cells.4,5 Thus, the sigma-2 receptor has been proposed as a suitable target for imaging proliferative tumor cells.

While many ligands are selective for the sigma-1 receptor or are nonselective, very few ligands
are selective for the sigma-2 receptor. A radiopharmaceutical based on an azabicyclo[3.3.1]nonane framework was developed by Mach,6 who demonstrated that the rhenium surrogate showed exceptional sigma-2 selectivity; later this agent was labeled with technetium-99m by Kung for tissue distribution studies.7 In considering potential fluorine-18
labeled sigma-2 receptor ligands, our attention focused on members of an indole piperidine series, especially 1 (LU 28-179), which is reported to have a remarkably high sigma-2 binding affinity  and selectivity.8,9 Figure 1. The structure of indole piperidine ligands and their inhibition constants toward sigma receptors.

Target compounds 1 and 2 were prepared in several steps by a route based on a previously
described method,7 with modifications making it more efficient for the synthesis of the precursor molecule (3); compounds 1 and 2 showed high binding affinity and good selectivity (6 fold) for the sigma-2 receptor (Figure 1). The preparation of [<SUP>18</SUP>F]-labeled indole piperidine [<SUP>18</SUP>F]1 was achieved in two steps from a o-nitroaldehyde precursor (3). Aromatic [<SUP>18</SUP>F]fluorination was not reproducible when 3 was treated with F-18 fluoride in the presence of Bu4NOH under microwave heating conditions. However, by using F-18, K<SUB>2</SUB>CO<SUB>3</SUB> and kryptofix[2.2.2] under microwave heating, we obtained radiochemical yields of 5-50%. The final decarbonylation step with Wilkinsons catalyst was studied in various solvents. Decarbonylation using dioxane as solvent produced [<SUP>18</SUP>F]1, but with toluene, extensive decomposition resulted. Herein, we present the synthesis of precursor 3, optimization of [<SUP>18</SUP>F]fluorination, and decarbonylation to produce [<SUP>18</SUP>F]Lu 28-179 (Scheme 1). Future work to prepare [<SUP>18</SUP>F]1 will be done using an alternate synthetic route.10
