This year, the Friends of Helmholtz-Zentrum Berlin (Freundeskreis des HZB e. V.) awarded the Ernst Eckhard Koch Prize to Dr. Dieter Skroblin of the Technische Universität Berlin for his outstanding doctoral thesis. The European Innovation Award Synchrotron Radiation went to Dr. Manfred Faubel from the Max Planck Institute for Dynamics and Self-Organization in Göttingen and Dr. Bernd Winter from the Fritz Haber Institute in Berlin. The award ceremony took place at this year's HZB user meeting.
The 2024 Synchrotron Radiation Innovation Prize was awarded to Dr. Manfred Faubel of the Max Planck Institute for Dynamics and Self-Organization in Göttingen and Dr. Bernd Winter of the Fritz Haber Institute in Berlin. They received the prize for their groundbreaking development and application of liquid jet photoelectron spectroscopy (LJ-PES). The method is widely used to study surface phenomena, biochemical reactions and atmospheric chemistry. Prof. Gerard Meijer from the Fritz Haber Institute in Berlin gave the laudatory speech at the award ceremony on December 11, 2024 in Berlin-Adlershof.
The Ernst-Eckhard-Koch Prize 2024 was awarded to Dr. Dieter Skroblin from the Technical University of Berlin. His dissertation “Application of X-ray Characterization Tools for ordered Nanostructures: Hybrid Detectors, Magnetic Sample Environment & Computational Simulations” was carried out at PTB and combines innovative X-ray scattering and spectrometry methods to study nanomaterials. Dr. Skroblin made significant progress in experimental setups and data interpretation, including the calibration of a hybrid pixel detector and the development of a device for aligning nanoparticles in a magnetic field. The award committee recognized the importance of his work for future research priorities at the planned synchrotron radiation source BESSY III.
Friends of Helmholtz-Zentrum Berlin e.V.
The "Friends of Helmholtz-Zentrum Berlin e. V." is dedicated to promoting science and research with synchrotron radiation, and in particular young scientists. It aims to be a link between the Helmholtz-Zentrum Berlin (HZB) and the public, and to cultivate cooperation between the HZB, its friends and supporters, and other institutions in Germany and abroad. The association's main activities include the annual awarding of the Ernst Eckhard Koch Dissertation Prize and the Synchrotron Radiation Innovation P
- BESSY II: How intrinsic oxygen shortens the lifespan of solid-state batteriesAlthough solid-state batteries (SSBs) demonstrate high performance and are intrinsically safe, their capacity currently declines rapidly. A team from the TU Wien, Humboldt-University Berlin and HZB has now analysed a TiS₂|Li₃YCl₆ solid-state half-cell in operando at BESSY II using a special sample environment that allows for non-destructive investigation under real operating conditions. Data obtained by combination of soft and hard X-ray photoelectron spectroscopy (XPS and HAXPES) revealed a new degradation mechanism that had not previously been identified in solid-state batteries. They have gained some surprising insights, particularly regarding the harmful role played by intrinsic oxygen. This study provides valuable information for improving design and handling of such batteries.
- Spintronics at BESSY II: Real-time analysis of magnetic bilayer systemsSpintronic devices enable data processing with significantly lower energy consumption. They are based on the interaction between ferromagnetic and antiferromagnetic layers. Now, a team from Freie Universität Berlin, HZB and Uppsala University has succeeded in tracking, for each layer separately, how the magnetic order changes after a short laser pulse has excited the system. They were also able to identify the main cause of the loss of antiferromagnetic order in the oxide layer: the excitation is transported from the hot electrons in the ferromagnetic metal to the spins in the antiferromagnet.
- Environmental Chemistry at BESSY II: Radicals in waterwaysHow do radicals form in aqueous solutions when exposed to UV light? This question is important for health research and environmental protection, for example with regard to the overfertilisation of water bodies by intensive agriculture. A team at BESSY II has now developed a new method of investigating hydroxyl radicals in solution. By using a clever trick, the scientists gained surprising insights into the reaction pathway.
