The first stop in the experimental hall is the hutch of the macromolecular crystallography research group. Manfred Weiss reports, among other things, on the research that led to the decoding of the three-dimensional structure of the main protease of the SARS-CoV2 virus.

This is the size of the pin on which a crystal is mounted where the brilliant X-ray light (synchrotron light) shines through. This allows researchers to peer into the matter and better understand its secrets.

On Friday, 17 June, a delegation from Singapore visited HZB. Heng Swee Keat, Deputy Prime Minister of Singapore, was accompanied by the Ambassador to Singapore in Germany, Laurence Bay, as well as representatives from research and industry.
It is the Prime Minister's first trip to Europe since the start of the pandemic. Before his stop in Berlin, he was in the UK, including London Tech Week and the Oxford Science Park.
The delegation led by Heng Swee Keat got some insights into HZB's energy and materials research as well as the science conducted at BESSY II light source and in the new catalyst laboratory CatLab.
All participants were delighted about the fruitful discussions and would like to deepen the scientific exchange between the two countries.
- Imaging Ellipsometry for Process Control of Thin-Film DevicesA German–Israeli research team led by Dr. Andreas Furchner has demonstrated how imaging ellipsometry enables non-destructive characterisation and quality control of microstructured MXene thin films during device fabrication. The authors used two complementary ellipsometry approaches for precise, multi-scale access to key material properties. The work positions imaging ellipsometry as a powerful platform for monitoring thin-film uniformity, device integrity, and functionality throughout processing, including critical lithographic steps. The study was published in Applied Physics Letters and selected as an Editor’s Pick.
- Cool vaccines in rural Kenya: solar solution has been awarded by UNIn May 2026, Tabitha Awuor Amollo is spending some weeks as a guest scientist at HZB, analysing perovskite thin films at BESSY II. The Kenyan physicist from Egerton University, Nairobi, was recently recognised for her achievements in research and teaching. For the development of a solar-powered refrigeration system for use in rural health centres, she has been awarded the 2026 Organization for Women in Science for the Developing World (OWSD)-Elsevier Foundation Award. An interview on exceptional projects and daily struggles of a scientist. Questions were asked by Antonia Rötger.
- 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.
