Department of Molecular Structures

Research

• X-ray absorption spectroscopy of actinides in environmentally relevant systems
• Determination of structural parameters for the near-neighbor environment of actinides by EXAFS:
  e.g. aqueous speciation, complexation with dissolved inorganic ligands like chloride, sulfate or nitrate complexation with organic ligands like acetate or humic acid, interaction with bacteria and plants,
  sorption to mineral and rock surfaces
• X-ray absorption spectroscopy of actinides and metalloids under reduced conditions, either by electrochemical reduction, inorganic reduction by Fe(II), or organic reduction by anaerobic microorganisms
• Structure of actinides in non-aqueous ionic liquids

Equipment

• Experiments are performed at the Rossendorf Beamline (BM20-ROBL), at the European Synchrotron Radiation Facility in Grenoble, France
• 13-element Ge fluorescence detector (Canberra) with digital signal analysis (XIA)
• Closed-cycle He cryostat (CryoVac)
• Modeling software: WinXAS, SixPack, Athena, Artemis, EXAFSPAK and FEFF8

The Molecular Structure Division runs the XAS station for Radiochemistry of the Rossendorf Beamline at the  European Synchrotron Radiation Facility in Grenoble, France.

Staff
