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.
- Catalysis research with the X-ray microscope at BESSY IIContrary to what we learned at school, some catalysts do change during the reaction: for example, certain electrocatalysts can change their structure and composition during the reaction when an electric field is applied. The X-ray microscope TXM at BESSY II in Berlin is a unique tool for studying such changes in detail. The results help to develop innovative catalysts for a wide range of applications. One example was recently published in Nature Materials. It involved the synthesis of ammonia from waste nitrates.
- BESSY II: Magnetic ‘microflowers’ enhance magnetic fields locallyA flower-shaped structure only a few micrometres in size made of a nickel-iron alloy can concentrate and locally enhance magnetic fields. The size of the effect can be controlled by varying the geometry and number of 'petals'. This magnetic metamaterial developed by Dr Anna Palau's group at the Institut de Ciencia de Materials de Barcelona (ICMAB) in collaboration with her partners of the CHIST-ERA MetaMagIC project, has now been studied at BESSY II in collaboration with Dr Sergio Valencia. Such a device can be used to increase the sensitivity of magnetic sensors, to reduce the energy required for creating local magnetic fields, but also, at the PEEM experimental station, to study samples under much higher magnetic fields than currently possible.
- Perovskite solar cells: New Young Investigator Group funded by BMBF at HZBIn the COMET-PV project, Dr Artem Musiienko aims to significantly accelerate the development of perovskite solar cells. He is using robotics and AI to analyse the many variations in the material composition of tin-based perovskites. The physicist will set up a Young Investigator Group at HZB. He will also have an affiliation with Humboldt University in Berlin, where he will gain teaching experience in preparation for a future professorship.
