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.
- Energy of charge carrier pairs in cuprate compoundsHigh-temperature superconductivity is still not fully understood. Now, an international research team at BESSY II has measured the energy of charge carrier pairs in undoped La₂CuO₄. Their findings revealed that the interaction energies within the potentially superconducting copper oxide layers are significantly lower than those in the insulating lanthanum oxide layers. These results contribute to a better understanding of high-temperature superconductivity and could also be relevant for research into other functional materials.
- Electrocatalysis with dual functionality – an overviewHybrid electrocatalysts can produce green hydrogen, for example, and valuable organic compounds simultaneously. This promises economically viable applications. However, the complex catalytic reactions involved in producing organic compounds are not yet fully understood. Modern X-ray methods at synchrotron sources such as BESSY II, enable catalyst materials and the reactions occurring on their surfaces to be analysed in real time, in situ and under real operating conditions. This provides insights that can be used for targeted optimisation. A team has now published an overview of the current state of knowledge in Nature Reviews Chemistry.
- Two precision mechanics from HZB are Berlin's best traineesTwo former apprentices from the HZB workshop have achieved something remarkable: Fiete Buchin and Edgar Lunk completed their training as precision mechanics, taking first and second place in all of Berlin. In this interview, they share what it took to reach the top, what makes their training special, and the advice they would give to future apprentices.
