"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!"
- Ultrafast dissociation of molecules studied at BESSY IIFor the first time, an international team has tracked at BESSY II how heavy molecules – in this case bromochloromethane – disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualise the ultrafast dynamics of this process. In this process, the X-ray photons trigger a "molecular catapult effect": light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier atoms - bromine and chlorine - separate more slowly.
- 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.
- BESSY II: New procedure for better thermoplasticsBio-based thermoplastics are produced from renewable organic materials and can be recycled after use. Their resilience can be improved by blending bio-based thermoplastics with other thermoplastics. However, the interface between the materials in these blends sometimes requires enhancement to achieve optimal properties. A team from the Eindhoven University of Technology in the Netherlands has now investigated at BESSY II how a new process enables thermoplastic blends with a high interfacial strength to be made from two base materials: Images taken at the new nano station of the IRIS beamline showed that nanocrystalline layers form during the process, which increase material performance.
