The "Journal of Magnetic Resonance" and the ISMAR (International Society of Magnetic Resonance) awarded Silvio Künstner with a Young Scientist Award for his talk "Rapid Scan EPR-on-a-chip". The doctoral student from the HZB institute for Nanospectroscopy presented current progress in the development of a miniaturized electron spin resonance spectrometer.
Electron spin resonance or electron paramagnetic resonance (EPR) provides detailed information about the inner structure of materials, down to an atomic level. This understanding of the material is essential for research in the field of renewable energies, such as efficient solar cells or battery electrodes. Of particular importance are experiments under real process conditions (operando measurements).
The chip-sized miniaturized EPR spectrometer presented by Silvio Künstner is so small that it can be inserted directly inside the sample. This improvement simplifies the handling of operando measurements significantly. In addition, EPR-on-a-chip is far more sensitive than conventional instruments. Next to the Helmholtz Zentrum Berlin, the University of Stuttgart, the Max Planck Institute for Chemical Energy Conversion, as well as the Karlsruhe Institute of Technology (KIT) and Bruker (as part of the BMBF's "EPRoC" project) are involved in the research of the miniature spectrometer.
Silvio Künstner received the Young Scientist Award at the ISMAR EUROMAR Joint Conference (25 - 30 August 2019) in Berlin, which was attended by more than 1000 scientists. At the world's largest conference in this field, the HZB was involved as co-organizer. Furthermore, researchers of the Helmholtz-Zentrum Berlin participated with more than ten presentations.
- 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).
- 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.
- Bernd Rech elected to the BR50 Board of DirectorsThe Scientific Director at Helmholt-Zentrum Berlin is the new face behind the "Natural Sciences" unit at Berlin Research 50 (BR50). Following the election in December 2025, the constituent meeting of the new BR50 Board of Directors took place on 22 January 2026.
Its members are Michael Hintermüller (Weierstrass Institute, WIAS), Noa K. Ha (German Centre for Integration and Migration Research, DeZIM), Volker Haucke (Leibniz Research Institute for Molecular Pharmacology, FMP), Uta Bielfeldt (German Rheumatism Research Centre Berlin, DRFZ) and Bernd Rech (HZB).
