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.

    New road towards spin-polarised currents
    The transition metal dichalcogenide (TMD) series are a family of promising candidate materials for spintronics. A study at lightsource BESSY II has unveiled that in one of those materials even simple linear polarised light is sufficient to selectively manipulate spins of different orientations. This result provides an entirely new route for the generation of spin-polarised currents and is a milestone for the development of spintronic and opto-spintronic devices.
