HZB Researcher on the Board of Directors of the Materials Research Society
Catherine Dubourdieu is head of the IFOX Institute at HZB and was elected now into the board of directors of the MRS.
In September 2019, Prof. Dr. Catherine Dubourdieu was elected into the Board of Directors of the Materials Research Society (MRS). The MRS is one of the largest scientific associations and has almost 14000 members from various areas of the natural sciences and engineering.
Catherine Dubourdieu heads the HZB-Institute IFOX (Functional Oxides for Energy Efficient Information Technology) and holds a professorship at the Freie Universität Berlin. She investigates the growth and properties of functional oxides and semiconductor materials with the aim of developing energy-efficient devices for information technology, that can be integrated on silicon chips. Over the past 15 years, the physicist has also established numerous collaborations with industry and holds 10 patents. She has already published over 140 articles in peer-review journals and has an excellent international network.
In the Materials Research Society Catherine Dubourdieu has been active for over 20 years, also in responsible functions. As of 2020, Catherine Dubourdieu will be a member of the MRS Board of Directors to support the global materials research community and provide a framework for the various disciplines to collaborate.
The MRS's mission is to advance international interdisciplinary materials research and technology for the benefit of the human society. It was founded in 1973 and today has around 14000 members from various areas of the natural sciences and engineering. The governance of the Society is the responsibility of the Board of Directors, composed of 6 officers and 18 directors, 15 of whom are elected by the membership. One third of the Board is renewed each year. Catherine Dubourdieu will serve in this position over the next three years.
- 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.
