discovered_01_2015 - Green Photonics Award 2015 for Dresden Researchers

discovered 01 .15 PORTRAIT WWW.HZDR.DE Green Photonics Award 2015 goes to Dresden researchers During SPIE PHOTONICS West 2015, the international meeting of the optics and photonics branch in San Francisco, the 2015 Green Photonics Award was conferred on a Dresden research team: Andrés Lasagni and Sebastian Eckhardt from the Institute of Manufacturing Technology at TU Dresden, Lars Müller- Meskamp from the Institute for Applied Photophysics and Mathias Siebold and Markus Löser from Helmholtz- Zentrum Dresden-Rossendorf. They were granted the award in the category ‘Laser-assisted manufacturing and micro/nano manufacturing’. The demand for highly-efficient, transparent electrodes, which do not use rare or expensive raw materials like indium, calls for a new generation of thin metallic films with both high transparency and electrical conductivity. A special laser-based method (‘direct laser interference patterning’) makes it possible to fabricate periodic hole-like surface patterns on thin metallic films. While it improves their optical transparency, it keeps the electrical properties of the very thin films at an acceptable level. The two HZDR researchers developed a solid-state laser specifically for structuring super-thin metal electrodes. To this end, they had to precisely adjust the emitted wavelengths of the laser system together with a high- output impulse energy for the manufacturing techniques at TU Dresden and Fraunhofer IWS. Thus the PhD student Sebastian Eckhardt managed to structure metallic electrodes made of very thin films for use in thin-film solar cells and LEDs. This successful cooperation between IWS and HZDR will continue in the joint LAMETA Project focusing on the manufacturing of embossing rollers with pattern sizes in the sub-micrometer range. Using laser technology, they will have to be manufactured so that they are suitable for the industrial production of plastic components with functional and microstructured surfaces. _National Center for Tumor Diseases Dresden Dr. Heidrun Groß heidrun.gross@uniklinikum-dresden.de http://www.nct-heidelberg.de/ CONTACT partners’ interests into account. If one gets short shrift, the whole construction starts to wobble. But everyone involved is convinced that it is a great opportunity for Dresden to have the NCT located here, and therefore cooperation between the various institutions has been very constructive.’ And that is not something to be taken for granted when one considers how many partners are involved. For the NCT partner site Dresden alone, Carl Gustav Carus University Hospital, the Medical Faculty at TU Dresden, the German Cancer Research Center (DKFZ) and HZDR have joined forces. ‘This location is already an excellent example for sustainable, successful research cooperation as OncoRay or DRESDEN- concept illustrate,’ Groß explains. Hence, this provides a good base for establishing the new NCT location. Dresden is thus becoming the partner site of Heidelberg where DKFZ, together with the University Hospital, the Medical Faculty at Heidelberg University and the German Cancer Aid, established NCT eleven years ago. As one center, Heidelberg and Dresden are now set to improve personalized cancer therapy. ‘The idea is to boost our strengths and also build additional profile areas,’ Groß explains. Research for the patient The approach taken by NCT is to combine research, treatment and prevention under one roof. Scientific results immediately flow into patient therapy – the experience of treatment feeds back into research. This cycle is designed to expedite the transfer of research results to clinical application. To this end, five new professorships are initially due to be created at NCT Dresden ‘which will be integrated in the institutions involved,’ Groß emphasizes. ‘In addition, we are also planning various programs that will build bridges to existing structures in oncology.’ On this basis, the entire NCT strives to become one of the world’s leading cancer research centers in the next ten years. Groß admits that this is an ambitious goal, but cooperation will generate the necessary potential, she believes. ‘Admittedly, you do get on quicker when you are on your own, but you get much further when you work together.’ AWARD WINNERS
