Uppsala Berlin Joint Laboratory “Our willingness to cooperate is our strength”
Great political interest for the new Uppsala Berlin Joint Laboratory (UBjL): On the 4th of November, Sweden’s ambassador in Germany, Dr. Lars Danielsson, came personally to the HZB where the UBjL is established for the inauguration of the joint project.
“Many parts of the world are currently regarded as more dynamic than Europe,” Dr. Danielsson said in his opening speech: “But we have great strengths – namely our skill and our willingness to cooperate.” These strengths, the ambassador continued, can be seen clearly in the UBjL: “Such excellent joint research projects lead to results that will bring great benefits to society, our children and our grandchildren.” Dr. Danielsson then gave the symbolic start signal for two experimental stations that will be supervised by the Swedish-German workgroup belonging to the UBjL.
The “Uppsala Berlin Joint Laboratory” is headed by Professor Nils Mårtensson, University of Uppsala, and Professor Alexander Föhlisch, Head of the HZB Institute “Methods and Instrumentation for Synchrotron Radiation Research. “We are very proud that Professor Mårtensson has invested resources from this ERC Advanced Grant in the UBjL,” HZB Scientific Director Prof. Dr. Anke Kaysser-Pyzalla said at the opening. This funding, co-financed by the HZB, has allowed the development of worldwide unique study methods for functional materials.
These methods are based on angle-resolved time-of-flight electron spectroscopy (ARTOF) and MHz pulse extraction at BESSY II. The ARTOF instruments were developed in Sweden by the University of Uppsala and the company Scienta-Omicron in close collaboration with the HZB. “The synchrotron source BESSY II delivers pulses with the most suitable time structure worldwide for optimally using the instruments,” said Svante Professor Svante Svensson, who is part of the UBjL team at BESSY II in Berlin. At the UBjL, the researchers can study the state of functional materials at the lowest possible X-ray dosage. Further methods allow detailed detection of the electronic structure of materials.
- Battery research with the HZB X-ray microscopeNew cathode materials are being developed to further increase the capacity of lithium batteries. Multilayer lithium-rich transition metal oxides (LRTMOs) offer particularly high energy density. However, their capacity decreases with each charging cycle due to structural and chemical changes. Using X-ray methods at BESSY II, teams from several Chinese research institutions have now investigated these changes for the first time with highest precision: at the unique X-ray microscope, they were able to observe morphological and structural developments on the nanometre scale and also clarify chemical changes.
- Hydrogen: Breakthrough in alkaline membrane electrolysersA team from the Technical University of Berlin, HZB, IMTEK (University of Freiburg) and Siemens Energy has developed a highly efficient alkaline membrane electrolyser that approaches the performance of established PEM electrolysers. What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium. At BESSY II, the team was able to elucidate the catalytic processes in detail using operando measurements, and a theory team (USA, Singapore) provided a consistent molecular description. In Freiburg, prototype cells were built using a new coating process and tested in operation. The results have been published in the prestigious journal Nature Catalysis.
- Rutger Schlatmann re-elected as ETIP PV ChairThe European Technology and Innovation Platform for Photovoltaics (ETIP PV) was created by the European Commission in order to promote photovoltaic technologies and industries in Europe. Now, the ETIP PV Steering Committee elected a new Chair, as well as two Vice-Chairs for the term 2024 – 2026. Rutger Schlatmann, head of the division Solar Energy at the HZB, and professor at HTW Berlin, was re-elected as the ETIP PV Chair.
