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.
- Battery research: visualisation of aging processes operandoLithium button cells with electrodes made of nickel-manganese-cobalt oxides (NMC) are very powerful. Unfortunately, their capacity decreases over time. Now, for the first time, a team has used a non-destructive method to observe how the elemental composition of the individual layers in a button cell changes during charging cycles. The study, now published in the journal Small, involved teams from the Physikalisch-Technische Bundesanstalt (PTB), the University of Münster, researchers from the SyncLab research group at HZB and the BLiX laboratory at the Technical University of Berlin. Measurements were carried out in the BLiX laboratory and at the BESSY II synchrotron radiation source.
- New instrument at BESSY II: The OÆSE endstation in EMILA new instrument is now available at BESSY II for investigating catalyst materials, battery electrodes and other energy devices under operating conditions: the Operando Absorption and Emission Spectroscopy on EMIL (OÆSE) endstation in the Energy Materials In-situ Laboratory Berlin (EMIL). A team led by Raul Garcia-Diez and Marcus Bär showcases the instrument’s capabilities via a proof-of-concept study on electrodeposited copper.
- Green hydrogen: A cage structured material transforms into a performant catalystClathrates are characterised by a complex cage structure that provides space for guest ions too. Now, for the first time, a team has investigated the suitability of clathrates as catalysts for electrolytic hydrogen production with impressive results: the clathrate sample was even more efficient and robust than currently used nickel-based catalysts. They also found a reason for this enhanced performance. Measurements at BESSY II showed that the clathrates undergo structural changes during the catalytic reaction: the three-dimensional cage structure decays into ultra-thin nanosheets that allow maximum contact with active catalytic centres. The study has been published in the journal ‘Angewandte Chemie’.
