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!"
- Fascinating archaeological find becomes a source of knowledgeThe Bavarian State Office for the Preservation of Historical Monuments (BLfD) has sent a rare artefact from the Middle Bronze Age to Berlin for examination using cutting-edge, non-destructive methods. It is a 3,400-year-old bronze sword, unearthed during archaeological excavations in Nördlingen, Swabia, in 2023. Experts have been able to determine how the hilt and blade are connected, as well as how the rare and well-preserved decorations on the pommel were made. This has provided valuable insight into the craft techniques employed in southern Germany during the Bronze Age. The BLfD used 3D computed tomography and X-ray diffraction to analyse internal stresses at the Helmholtz-Zentrum Berlin (HZB), as well as X-ray fluorescence spectroscopy at a BESSY II beamline supervised by the Bundesanstalt für Materialforschung und -prüfung (BAM).
- Element cobalt exhibits surprising propertiesThe element cobalt is considered a typical ferromagnet with no further secrets. However, an international team led by HZB researcher Dr. Jaime Sánchez-Barriga has now uncovered complex topological features in its electronic structure. Spin-resolved measurements of the band structure (spin-ARPES) at BESSY II revealed entangled energy bands that cross each other along extended paths in specific crystallographic directions, even at room temperature. As a result, cobalt can be considered as a highly tunable and unexpectedly rich topological platform, opening new perspectives for exploiting magnetic topological states in future information technologies.
- MXene for energy storage: More versatile than expectedMXene materials are promising candidates for a new energy storage technology. However, the processes by which the charge storage takes place were not yet fully understood. A team at HZB has examined, for the first time, individual MXene flakes to explore these processes in detail. Using the in situ Scanning transmission X-ray microscope 'MYSTIIC' at BESSY II, the scientists mapped the chemical states of Titanium atoms on the MXene flake surfaces. The results revealed two distinct redox reactions, depending on the electrolyte. This lays the groundwork for understanding charge transfer processes at the nanoscale and provides a basis for future research aimed at optimising pseudocapacitive energy storage devices.
