Friedrich-Alexander Universität Erlangen-Nürnberg appoints Olga Kasian
Olga Kasian has accepted a professorship at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU).
Dr. Olga Kasian is investigating why catalysts for hydrogen production by water electrolysis are limited in efficiency. The chemist has now accepted a professorship at the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU). The W2 professorship is entitled "Materials for Electrochemical Energy Conversion" and is located at the Faculty of Engineering.
Olga Kasian completed her doctorate in 2013 at the State University of Chemical Technology in Dnepropetrovsk, Ukraine, and was awarded as best young scientist of Dnepropetrovsk region in field of chemical technology. After a first postdoctoral stay in Germany, she joined the Max Planck Institute for Iron Research in Düsseldorf as an Alexander von Humboldt Research Fellow in 2015. That year she got the Award of the President of Ukraine for Young Scientists. Since May 2019, she has been leading the Helmholtz Young Investigator Group 'Dynamic Electrocatalytic Interfaces' at HZB and the Helmholtz Institute Erlangen-Nuremberg for Renewable Energies (HI-ERN).
Together with her team, she is investigating how the catalytically active surfaces change under reaction conditions, using a wide range of methods including state of the art spectroscopy techniques available at the EMIL-Lab at the synchrotron radiation source BESSY II.
- 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’.
