Sixth Joint BER II and BESSY II User Meeting
The annual Joint HZB User Meetings will provide an overview of the many exciting and inspiring research results obtained at our facilities in the past year. The Sixth Joint BER II and BESSY II User Meeting will take place at Berlin-Adlershof from December 3rd to December 5th, 2014. The neutrons session will take place at Berlin-Wannsee on Wednesday, 3rd December, followed by Dinner at Café Jahn.
On Thursday morning, at WISTA, Bunsen Auditorium, Adlershof, Christof Wöll, KIT, will ask in his keynote lecture “What Supramolecular Chemistry can do for Solid State Physics?” The meeting continues with plenary talks, discussions, and a poster session, which will provide vast possibilities of information and discussion. In his public lecture, Christoph Lienau, University Oldenburg, will give an overview on “Solar cells and artificial light harvesting systems”.
Traditional highlights are the bestowals of the Prizes for Young Scientists donated by the “Freundeskreis Helmholtz-Zentrum Berlin e. V. “
After hours of inspiring scientific presentations we hope to meet you Thursday evening at the Berliner Buffet. The buffet is sponsored by the companies participating in the accompanying vendor exhibition. As well as this generous gesture the exhibitors will be happy to have the opportunity to inform you on the latest developments in all fields of research equipment.

- What vibrating molecules might reveal about cell biologyInfrared vibrational spectroscopy at BESSY II can be used to create high-resolution maps of molecules inside live cells and cell organelles in native aqueous environment, according to a new study by a team from HZB and Humboldt University in Berlin. Nano-IR spectroscopy with s-SNOM at the IRIS beamline is now suitable for examining tiny biological samples in liquid medium in the nanometre range and generating infrared images of molecular vibrations with nanometre resolution. It is even possible to obtain 3D information. To test the method, the team grew fibroblasts on a highly transparent SiC membrane and examined them in vivo. This method will provide new insights into cell biology.
- Iridium-free catalysts for acid water electrolysis investigatedHydrogen will play an important role, both as a fuel and as a raw material for industry. However, in order to produce relevant quantities of hydrogen, water electrolysis must become feasible on a multi-gigawatt scale. One bottleneck is the catalysts required, with iridium in particular being an extremely rare element. An international collaboration has therefore investigated iridium-free catalysts for acidic water electrolysis based on the element cobalt. Through investigations with various methods, among them experiments at the LiXEdrom at the BESSY II X-ray source in Berlin, they were able to elucidate processes that take place during water electrolysis in a cobalt-iron-lead oxide material as the anode. The study is published in Nature Energy.
- Catalysis research with the X-ray microscope at BESSY IIContrary to what we learned at school, some catalysts do change during the reaction: for example, certain electrocatalysts can change their structure and composition during the reaction when an electric field is applied. The X-ray microscope TXM at BESSY II in Berlin is a unique tool for studying such changes in detail. The results help to develop innovative catalysts for a wide range of applications. One example was recently published in Nature Materials. It involved the synthesis of ammonia from waste nitrates.
