Jan Lüning heads HZB Institute for Electronic Structure Dynamics
© HG Medien
The HZB Institute for Electronic Structure Dynamics, newly founded on 1 May, develops experimental techniques and infrastructures to investigate the dynamics of elementary microscopic processes in novel material systems. This will help to optimise functional materials for sustainable technologies.
Prof. Dr. Jan Lüning is an internationally recognised expert in research with synchrotron radiation. Before joining HZB in 2018, he was a professor at Sorbonne University in Paris and worked at the French synchrotron SOLEIL.
Three groups belong to the institute: Dr Ulrich Schade's group operates the IRIS infrared beamline at the BESSY II synchrotron radiation source. He examines molecular processes in novel functional materials that enable, for example, energy conversion or catalytic water splitting.
The group "Ultra-Short-Time Laser Spectroscopy" led by Dr. Iain Wilkinson works in the laser laboratories ULLAS and LIDUX and investigates the dynamics of reactions in aqueous solutions and at aqueous interfaces on ultra-short time scales.
The third group, led by Dr. Christian Schüssler-Langeheine and Dr. Niko Pontius, operates the Femtoslicing Facility at BESSY II and conducts research on materials with complex phase transitions that have the potential to make electronic and magnetic devices smaller, faster and more energy efficient.
The institute's research activities are part of the Helmholtz Association's Programme-Oriented Funding (POF IV) in the Research Field Matter.
- BESSY II: High-resolution insights into individual biomolecules and catalystsVery small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline with a newly validated and improved technique: The nanoscale infrared spectroscopy (s-SNOM) with ultra-thin silicon-based membranes. An international team demonstrated after an initial proof of concept, that high-resolution (a few tens of nanometres) nano-IR measurements reliably match expected far-field IR spectra in an aqueous environment. This methodological advance provides a solid foundation for studying biomaterials or observing catalytic processes in a liquid environment.
- New method shows how molecular switches are influenced by their neighborsResearchers at Friedrich Schiller University Jena and the Helmholtz Centre Berlin (HZB) have, for the first time, been able to directly observe how the environment surrounding a molecular switch influences its electronic structure. Molecular switches are molecules that can be switched between two states by external influences such as changes in temperature—similar to a switch with the positions »On« and »Off«. Such molecules are being investigated as potential building blocks for future data storage devices or sensor materials. Using magnetic-field-dependent terahertz spectroscopy, the researchers have now, for the first time, been able to distinguish whether neighbouring molecules in a material are in the same or different states. The results have been published in the journal »Angewandte Chemie International Edition«.
- BESSY II is back in operation after maintenance shutdownOn 7 September 2026, BESSY II was set into operation after a four-week shutdown. BESSY II is scheduled to resume full user operation on 22 September.
