German Society for Materials Science awards publication with HZB scientist as co-author
At its annual conference on September 22, 2014, the German Society for Materials Science (DGM), presented the Werner Köster Award for best publication. The work, whose authors include HZB scientist Dr. Michael Tovar and which has been published in the International Journal of Materials Research, examines the catalytic effect of vanadium pentoxide in propene synthesis from propane using spectroscopic, microscopic, and radiographic methods.
In order to better understand the various processes involved in propene synthesis from propane using the catalyst V2O5-x, scientists at the TU Berlin's Institute for Materials Sciences together with a team of researchers from Humboldt University and HZB's own Michael Tovar analyzed samples of this catalyst. They were able to show that reduction of V2O5-x starts at temperatures of 380 degrees C. Radiographic measurements that were analyzed with the help of HZB support offered important clues about how, during the reduction of oxygen, its release leads to formation of oxygen vacancies within the crystalline lattice.

- Lithium-sulphur pouch cells investigated at BESSY IIA team from HZB and the Fraunhofer Institute for Material and Beam Technology (IWS) in Dresden has gained new insights into lithium-sulphur pouch cells at the BAMline of BESSY II. Supplemented by analyses in the HZB imaging laboratory and further measurements, a new picture emerges of processes that limit the performance and lifespan of this industrially relevant battery type. The study has been published in the prestigious journal Advanced Energy Materials.
- Largest magnetic anisotropy of a molecule measured at BESSY IIAt the Berlin synchrotron radiation source BESSY II, the largest magnetic anisotropy of a single molecule ever measured experimentally has been determined. The larger this anisotropy is, the better a molecule is suited as a molecular nanomagnet. Such nanomagnets have a wide range of potential applications, for example, in energy-efficient data storage. Researchers from the Max Planck Institute for Kohlenforschung (MPI KOFO), the Joint Lab EPR4Energy of the Max Planck Institute for Chemical Energy Conversion (MPI CEC) and the Helmholtz-Zentrum Berlin were involved in the study.
- Ernst Eckhard Koch Prize and Synchrotron Radiation Innovation AwardThis year, the Friends of Helmholtz-Zentrum Berlin (Freundeskreis des HZB e. V.) awarded the Ernst Eckhard Koch Prize to Dr. Dieter Skroblin of the Technische Universität Berlin for his outstanding doctoral thesis. The European Innovation Award Synchrotron Radiation went to Dr. Manfred Faubel from the Max Planck Institute for Dynamics and Self-Organization in Göttingen and Dr. Bernd Winter from the Fritz Haber Institute in Berlin. The award ceremony took place at this year's HZB user meeting.
