"BESSY is of immense importance for Berlin"

At the end of August, the Senator for Research, Health, and Long-Term Care, Dr Ina Czyborra, together with the State Secretary for Science, Dr Henry Marx, ended her summer tour with a visit to HZB in Adlershof. She publicly declared her political support for the new construction of BESSY III.
Ina Czyborra took an afternoon for intensive discussions with scientists and BESSY II light source. The focus was on the versatility of this large and powerful research infrastructure: from the decoding of protein structures to groundbreaking innovations in the field of renewable energies.
Political support for BESSY III
A central topic was the successor source BESSY III (More information). HZB is planning a 4th generation light source with integrated laboratories, which is to be embedded in the Berlin-Adlershof research campus. The Senator expressly supports this project:
"Once again, I have seen cutting-edge research that is attracting worldwide attention. Adlershof has everything that makes Berlin a unique location - science, research and business in proximity, cooperating and benefiting from each other. [...] This makes it even more important to set the course in the Senate's budget deliberations, which begin in September, to ensure that Berlin remains a centre of cutting-edge research with international appeal in the future. Incidentally, we also need BESSY III for this. The continuation of BESSY is of immense importance for Berlin as a research location. That is why I will do everything I can to ensure that this project is continued."
"We are extremely pleased about such a clear commitment to our plans to build BESSY III in Berlin-Adlershof," says Prof. Bernd Rech, Scientific Director of HZB. "The exchange with the Senator for Science underlines how important the dialogue between science and politics is. Especially when it comes to further advancing cutting-edge research in Berlin!"
- 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.
- 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.
