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.
- Key technology for a future without fossil fuelsIn June and July 2025, catalyst researcher Nico Fischer spent some time at HZB. It was his sabbatical, he was relieved of his duties as Director of the Catalysis Institute in Cape Town for several months and was able to focus on research only. His institute is collaborating with HZB on two projects that aim to develop environmentally friendly alternatives using innovative catalyst technologies. The questions were asked by Antonia Rötger, HZB.
- 5000th patient treated with protons for eye tumoursFor more than 20 years, Charité – Universitätsmedizin Berlin and the Helmholtz-Zentrum Berlin (HZB) have been jointly offering proton radiation therapy for eye tumours. The HZB operates a proton accelerator in Berlin-Wannsee for this purpose, while Charité provides medical care for the patients. The 5000th patient was treated at the beginning of August.
- Iridium-free catalysts for acid water electrolysis investigatedHydrogen will play an important role, both as a fuel and as a raw material for industry. However, in order to produce relevant quantities of hydrogen, water electrolysis must become feasible on a multi-gigawatt scale. One bottleneck is the catalysts required, with iridium in particular being an extremely rare element. An international collaboration has therefore investigated iridium-free catalysts for acidic water electrolysis based on the element cobalt. Through investigations with various methods, among them experiments at the LiXEdrom at the BESSY II X-ray source in Berlin, they were able to elucidate processes that take place during water electrolysis in a cobalt-iron-lead oxide material as the anode. The study is published in Nature Energy.
