Under the EU Horizon 2020 Programme for Research and Innovation, Alexander Föhlisch has been awarded an ERC Advanced Grant. The physicists is holding a joint appointment at the Institute for Physics and Astronomy of the University of Potsdam and at the Helmholtz-Zentrum Berlin für Materialien und Energie. He is to receive a total of 2.5 million Euros over a five-year period to support his work on highly selective methods of detection using synchrotron light and X-ray lasers.
The European Research Council (ERC) promotes unconventional, trailblazing research and supports outstanding researchers. Leading scientists at the University of Potsdam are presently carrying out work under six other ERC grants.
The new research project is named “Excited-State Dynamics from Anti-Stokes and Non-Linear Resonant Inelastic X-Ray Scattering” (EDAX). Under this programme, Prof. Föhlisch will study how chemical reaction pathways and phase-transition behaviour can be probed using novel X-ray spectrographic methods. These will serve as a foundation for efficient energy conversion and future energy-efficient information technologies. The University of Potsdam is pushing ahead with cutting-edge research through the EDAX project and consolidating the rising success of the University in EU research programmes.
Alexander Föhlisch studied physics at Eberhard Karls Universität Tübingen and received his German Diplom degree from the University of Hamburg and Master’s degree in physics from the State University of New York at Stony Brook (SUNY). Prior to completing his research and teaching responsibilities for his professorial qualification in Experimental Physics at the University of Hamburg, he conducted his doctoral research at the Advanced Light Source of the Lawrence Berkeley National Laboratory and received his doctoral degree from Uppsala University in Sweden. As a jointly appointed Professor at the University of Potsdam and the Helmholtz-Zentrum Berlin, he is determining the electronic structure and ultrafast dynamics of atomic entities using innovative X-ray methods. Fundamental properties of materials – such as molecular dynamics at boundaries, switching processes in solids and chemical bonding at active centres – can be determined this way.
- BESSY II: How pulsed charging enhances the service time of batteriesAn improved charging protocol might help lithium-ion batteries to last much longer. Charging with a high-frequency pulsed current reduces ageing effects, an international team demonstrated. The study was led by Philipp Adelhelm (HZB and Humboldt University) in collaboration with teams from the Technical University of Berlin and Aalborg University in Denmark. Experiments at the X-ray source BESSY II were particularly revealing.
- Fuel Cells: Oxidation processes of phosphoric acid revealed by tender X-raysThe interactions between phosphoric acid and the platinum catalyst in high-temperature PEM fuel cells are more complex than previously assumed. Experiments at BESSY II with tender X-rays have decoded the multiple oxidation processes at the platinum-electrolyte interface. The results indicate that variations in humidity can influence some of these processes in order to increase the lifetime and efficiency of fuel cells.
- Best Innovator Award 2023 for Artem MusiienkoDr. Artem Musiienko has been awarded a special prize for his groundbreaking new method for characterising semiconductors. At the recent annual conference of the Marie Curie Alumni Association (MCAA) in Milan, Italy, he received the MCAA Award for the best innovation. Since 2023, Musiienko has been carrying out his research project with a postdoctoral fellowship from the Marie Sklodowska Curie Actions in Antonio Abate's department, Novel Materials and Interfaces for Photovoltaic Solar Cells (SE-AMIP).
