Two new Helmholtz Young Investigator Groups will start in 2019
Starting in 2019, Helmholtz-Zentrum Berlin (HZB) will be establishing two new Helmholtz Young Investigator Groups and thereby strengthening its competencies in catalysis research. The Helmholtz Association will be funding each group with 150,000 euros annually over a period of five years, and HZB will be matching that sum with its own funds.
The group of Dr. Christopher Seiji Kley will be developing light-absorbing materials and catalysts for the sunlight-driven conversion of carbon dioxide and water into fuels. The Young Investigator Group will be introducing concepts inspired from biology as a way to increase the catalysts’ energy efficiency and to maximise the catalytic activity for longer-chain hydrocarbons. The planned start for the group is in March 2019.
Dr. Olga Kasian’s group will be researching what are the factors currently limiting the performance of catalysts in solar hydrogen production. To do so, they will be analysing the catalysts’ uppermost atomic layers and explaining the reaction mechanisms by directly detecting the intermediates and products. BESSY II offers the latest spectroscopic methods for studying the electronic changes in the materials in-operando. Olga Kasian’s Young Investigator Group will kick off in May 2019.
Two out of ten new Helmholtz Young Investigator Groups at HZB
In the recent selection process for heads of Young Investigator Groups, an interdisciplinary jury selected ten talents from a total of 23 applicants. HZB came out very successfully in the selection round: out of ten newly funded Helmholtz Young Investigator Groups, two are to be established at HZB in 2019.
About the “Helmholtz Young Investigators” programme
The research programme fosters highly qualified young researchers who completed their doctorate three to six years ago. The heads of the Young Investigator Groups receive support through a tailored training and mentoring programme and are assured long-term prospects at HZB. One aim of the programme is to strengthen the networking of Helmholtz centres and universities. The costs – 300,000 euros per year per group over five years – are covered half by the Helmholtz President’s Initiative and Networking Fund, and half by the Helmholtz centres.
- 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.
