For the past two years, Dr Renske van der Veen has led a research group in time-resolved X-ray spectroscopy and electron microscopy at HZB. Her research focuses on catalytic processes that enable, for example, the production of green hydrogen. She has now been appointed to a S-W2 professorship at the Institute of Optics and Atomic Physics (IOAP) at the Technische Universität Berlin.
Dr Renske van der Veen specialises in ultrafast X-ray methods, which she uses at BESSY II to study the fast processes involved in catalysis. Van der Veen is also contributing her expertise to the scientific requirements profile for the successor X-ray source BESSY III.
Renske van der Veen studied at the ETH Zurich and completed her PhD at the École Polytechnique Fédérale de Lausanne (EPFL). She went on to do research at the California Institute of Technology, the Max Planck Institute for Biophysical Chemistry in Göttingen and the University of Illinois, where she was also an assistant professor. She has received the Alexander von Humboldt Foundation's Sofja Kovalevskaja Award and the Packard Fellowship for Science and Engineering.
Green Deal Ukraina: HZB launches an Energy & Climate Project
Green Deal Ukraina, funded by the German Federal Ministry of Education and Research, is working with partner institutions in Ukraine and Poland to establish an energy and climate think tank in the capital, Kiev. The aim is to provide independent and evidence-based advice on rebuilding a sustainable energy system in Ukraine. After all, the implementation of energy and climate legislation is a prerequisite for Ukraine's accession to the EU. The project started on 1 June 2023 and will run for four years.
Spintronics at BESSY II: Domain walls in magnetic nanowires
Magnetic domains walls are known to be a source of electrical resistance due to the difficulty for transport electron spins to follow their magnetic texture. This phenomenon holds potential for utilization in spintronic devices, where the electrical resistance can vary based on the presence or absence of a domain wall. A particularly intriguing class of materials are half metals such as La2/3Sr1/3MnO3 (LSMO) which present full spin polarization, allowing their exploitation in spintronic devices. Still the resistance of a single domain wall in half metals remained unknown. Now a team from Spain, France and Germany has generated a single domain wall on a LSMO nanowire and measured resistance changes 20 times larger than for a normal ferromagnet such as Cobalt.
Graphene on titanium carbide triggers a novel phase transition
Researchers have discovered a Lifshitz-transition in TiC, driven by a graphene overlayer, at the photon source BESSY II. Their study sheds light on the exciting potential of 2D materials such as graphene and the effects they can have on neighboring materials through proximity interactions.
