"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!"
- BESSY II: How intrinsic oxygen shortens the lifespan of solid-state batteriesAlthough solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.
- Spintronics at BESSY II: Real-time analysis of magnetic bilayer systemsSpintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking, for each layer separately, how the magnetic order changes after a short laser pulse has excited the system. They were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: the excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet.
- Environmental Chemistry at BESSY II: Radicals in waterwaysHow do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection, for example with regard to the overfertilisation of water bodies by intensive agriculture. A team at BESSY II has now developed a new method of investigating hydroxyl radicals in solution. By using a clever trick, the scientists gained surprising insights into the reaction pathway.
