20 Years Russian-German Joint Laboratory at BESSY II
To mark its 20th anniversary, the Russian-German Laboratory at the BESSY II storage ring for synchrotron radiation in Berlin is organising an online workshop on 18 and 19 November. Scientists will discuss the future perspectives of Russian-German cooperation as well as innovative projects and new goals of the laboratory.
Since its foundation two decades ago, numerous scientists from Russia and Germany have worked at the Russian-German Joint Laboratory and have since published around 770 publications. The research cooperation is now supported by eight partner organisations - Freie Universität Berlin, Helmholtz-Zentrum Berlin, Technische Universität Dresden and Technische Universität Bergakademie Freiberg. They are joined by St. Petersburg State University, the Ioffe Institute in St. Petersburg and the Kurchatov Institute and Shubnikov Institute of Crystallography in Moscow.
The laboratory receives funding from the Federal Ministry of Education and Research. Messreisen supports the HZB and the German-Russian Centre of Excellence G-RISC, which is funded by the German Academic Exchange Service (DAAD) with funds from the Federal Foreign Office.
The researchers will use the anniversary workshop to discuss current highlights from their research. Expert lectures will deal with the magnetism of two-dimensional crystals, i.e. novel materials that can make the computer hardware of the future more powerful and energy-efficient, as well as new battery materials and the question of why novel materials for solar cells show unexpectedly high efficiency. "What does the future hold for the Russian-German Laboratory?" asks Eckart Rühl, Professor of Physical Chemistry at the Free University of Berlin and coordinator of the research laboratory. New synchrotron radiation sources are already being planned in Germany and Russia, he says. "BESSY II will continue to provide excellent opportunities for the Russian-German Laboratory in the coming decade. And the planned successor source BESSY III will make previously unfeasible experiments possible!" emphasises Prof. Dr. Jan Lüning, scientific director of Helmholtz-Zentrum Berlin.
- Atomic displacements in High-Entropy Alloys examinedHigh-entropy alloys of 3d metals have intriguing properties that are interesting for applications in the energy sector. An international team at BESSY II has now investigated the local order on an atomic scale in a so-called high-entropy Cantor alloy of chromium, manganese, iron, cobalt and nickel. The results from combined spectroscopic studies and statistical simulations expand the understanding of this group of materials.
- Deputy Prime Minister of Singapore visits HZBOn Friday, 17 June, a delegation from Singapore visited HZB. Heng Swee Keat, Deputy Prime Minister of Singapore, was accompanied by the Ambassador to Singapore in Germany, Laurence Bay, as well as representatives from research and industry.
- Calculating the "fingerprints" of molecules with artificial intelligenceWith conventional methods, it is extremely time-consuming to calculate the spectral fingerprint of larger molecules. But this is a prerequisite for correctly interpreting experimentally obtained data. Now, a team at HZB has achieved very good results in significantly less time using self-learning graphical neural networks.
