International conference QENS 2016 and Workshop WINS 2016 in Potsdam
Participants of QENS 2016 and WINS 2016
From 5th to 9th of September HZB has hosted two international scientific events dedicated to the study of the dynamics at nanoscale, QENS and WINS 2016. While Quasielastic Neutron scattering conference (QENS 2016) was dedicated to the scientific applications, international Workshop on Inelastic spectrometers WINS 2016 allowed to touch on the instrumental aspects. 108 scientists from all over the world participated in these events organized in the heart of the Potsdam.
For the first time in the history of QENS the conference was focused on the exploration of materials for energy and information technology applications. Modeling, either to deeper understanding of experimental data, or in the prediction of new materials and phenomena was integral part of the programme. A special session will be dedicated to water. “Very nice program, perfect organization and all this in such a nice place!” summarized Jean-Marc Zanotti from Saclay, France.
- A new way to control the magnetic properties of rare earth elementsThe special properties of rare earth magnetic materials are due to the electrons in the 4f shell. Until now, the magnetic properties of 4f electrons were considered almost impossible to control. Now, a team from HZB, Freie Universität Berlin and other institutions has shown for the first time that laser pulses can influence 4f electrons- and thus change their magnetic properties. The discovery, which was made through experiments at EuXFEL and FLASH, opens up a new way to data storage with rare earth elements.
- HZB magazine lichtblick - the new issue is out!In his search for the perfect catalyst, HZB researcher Robert Seidel is now getting a tailwind – thanks to a ERC Consolidator Grant. In the cover story, we explain why the X-ray source BESSY II plays an important role for his research.
- BESSY II shows how solid-state batteries degradeSolid-state batteries have several advantages: they can store more energy and are safer than batteries with liquid electrolytes. However, they do not last as long and their capacity decreases with each charge cycle. But it doesn't have to stay that way: Researchers are already on the trail of the causes. In the journal ACS Energy Letters, a team from HZB and Justus-Liebig-Universität, Giessen, presents a new method for precisely monitoring electrochemical reactions during the operation of a solid-state battery using photoelectron spectroscopy at BESSY II. The results help to improve battery materials and design.
