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.
- What Zinc concentration in teeth revealsTeeth are composites of mineral and protein, with a bulk of bony dentin that is highly porous. This structure is allows teeth to be both strong and sensitive. Besides calcium and phosphate, teeth contain trace elements such as zinc. Using complementary microscopy imaging techniques, a team from Charité Berlin, TU Berlin and HZB has quantified the distribution of natural zinc along and across teeth in 3 dimensions. The team found that, as porosity in dentine increases towards the pulp, zinc concentration increases 5~10 fold. These results help to understand the influence of widely-used zinc-containing biomaterials (e.g. filling) and could inspire improvements in dental medicine.
- 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.
