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.
Program of the Workshop on 18 and 19 November 2021
- Susanne Nies appointed to EU advisory group on Green DealDr. Susanne Nies heads the Green Deal Ukraina project at HZB, which aims to support the development of a sustainable energy system in Ukraine. The energy expert has now also been appointed to the European Commission's scientific advisory group to comment on regulatory burdens in connection with the net-zero target (DG GROW).
- The future of corals – what X-rays can tell usThis summer, it was all over the media. Driven by the climate crisis, the oceans have now also passed a critical point, the absorption of CO2 is making the oceans increasingly acidic. The shells of certain sea snails are already showing the first signs of damage. But also the skeleton structures of coral reefs are deteriorating in more acidic conditions. This is especially concerning given that corals are already suffering from marine heatwaves and pollution, which are leading to bleaching and finally to the death of entire reefs worldwide. But how exactly does ocean acidification affect reef structures?
Prof. Dr. Tali Mass, a marine biologist from the University of Haifa, Israel, is an expert on stony corals. Together with Prof. Dr. Paul Zaslansky, X-ray imaging expert from Charité Berlin, she investigated at BESSY II the skeleton formation in baby corals, raised under different pH conditions. Antonia Rötger spoke online with the two experts about the results of their recent study and the future of coral reefs.
- Long-term stability for perovskite solar cells: a big step forwardPerovskite solar cells are inexpensive to produce and generate a high amount of electric power per surface area. However, they are not yet stable enough, losing efficiency more rapidly than the silicon market standard. Now, an international team led by Prof. Dr. Antonio Abate has dramatically increased their stability by applying a novel coating to the interface between the surface of the perovskite and the top contact layer. This has even boosted efficiency to almost 27%, which represents the state-of-the-art. After 1,200 hours of continuous operation under standard illumination, no decrease in efficiency was observed. The study involved research teams from China, Italy, Switzerland and Germany and has been published in Nature Photonics.
