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.
- 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.
- Too old for research at 60? From nuclear physics to papyrus researchA career in science can be personally fulfilling. However, this also means accepting the unpredictable: research topics may no longer receive funding, and laboratories may close. Heinz-Eberhard Mahnke experienced this first-hand when he had to seek new challenges in his early 60s. Today, the 81-year-old is still active in research, using non-destructive measurement methods to examine ancient artefacts of inestimable cultural value. Antonia Rötger spoke with this extraordinary researcher, whose curiosity and drive are truly inspiring.
- Spintronics at BESSY II: Real-time analysis of magnetic bilayer systemsSpintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking, for each layer separately, how the magnetic order changes after a short laser pulse has excited the system. They were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: the excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet.
