On December 6, 2018, the Association of Friends of Helmholtz-Zentrum Berlin awarded the Ernst Eckhard Koch Prize for an outstanding doctoral thesis in the field of research with synchrotron radiation at the HZB or at DESY as well as the European Innovation-Award on Synchrotron Radiation. The award ceremonies took place during the 10th User Meeting at the HZB.
The decisions between excellent proposals have not been easy for the two selection committees, Prof. Mathias Richter, chairman of the “Friends of HZB” pointed out.
The Ernst Eckhard Koch Prize went to Dr. Victoriia Saveleva for her doctorate at the University of Strasbourg on in-situ investigations of electrochemical processes using photoemission spectroscopy. Her experiments at BESSY II focused on reactions on catalyst surfaces of ruthenium and iridium during the electrolytic decomposition of water. Saveleva is now a postdoctoral researcher at the Paul Scherrer Institute in Switzerland.
The Innovation Award on Synchrotron Radiation 2018 went to Dr. Christian David, also from the Paul Scherrer Institute, and to Prof. Alexei Erko, who recently moved from the HZB to the Institute for Applied Photonics (IAP) in Berlin-Adlershof. The two physicists were honored for their innovative contributions to the application of diffractive X-ray optics, which enable complex X-ray experiments with high resolution. The laudation was held by Prof. Gerd Schneider from the HZB. This time it was not the "ring makers" who were honoured for developing the accelerators, but those who had cut the "diamonds for the ring", Schneider explained pictorially. The Synchrotron Radiation Innovation Award is sponsored by SPECS GmbH and BESTEC GmbH.
- Porous Radical Organic framework improves lithium-sulphur batteriesA team led by Prof. Yan Lu, HZB, and Prof. Arne Thomas, Technical University of Berlin, has developed a material that enhances the capacity and stability of lithium-sulphur batteries. The material is based on polymers that form a framework with open pores (known as radical-cationic covalent organic frameworks or COFs). Catalytically accelerated reactions take place in these pores, firmly trapping polysulphides, which would shorten the battery life. Some of the experimental analyses were conducted at the BAMline at BESSY II.
- Metallic nanocatalysts: what really happens during catalysisUsing a combination of spectromicroscopy at BESSY II and microscopic analyses at DESY's NanoLab, a team has gained new insights into the chemical behaviour of nanocatalysts during catalysis. The nanoparticles consisted of a platinum core with a rhodium shell. This configuration allows a better understanding of structural changes in, for example, rhodium-platinum catalysts for emission control. The results show that under typical catalytic conditions, some of the rhodium in the shell can diffuse into the interior of the nanoparticles. However, most of it remains on the surface and oxidises. This process is strongly dependent on the surface orientation of the nanoparticle facets.
