Interface Chemistry and Structure
At the Interface Chemistry and Structure group, we investigate solid-liquid interfaces, which are fundamental to both natural and technological processes. These interfaces are a critical nexus for energy conversion, catalysis, and environmental remediation. They are where electrons meet molecules, and where the interplay between electrode surfaces, solvent molecules, and ions determines the activity and selectivity of reactions.
Our research combines cutting-edge in situ microscopy with detailed structural analysis to uncover how nanoscale interfacial heterogeneities, in both electrode surfaces and the three-dimensional solvent organization, govern macroscopic performance. Through these insights, we aim to enable knowledge-driven design of next generation catalysts and clean energy technologies.

76th Annual Meeting of the International Society of Electrochemistry
Lucas and Andrea attended the 76th Annual Meeting of the ISE in Mainz, Germany. The conference featured over 2000 contributions, making it the annual meeting with the highest participant number in its history. Lucas contributed his first poster presentation to the conference. Andrea gave an invited talk on visualizing solvent structuring at electrified solid-liquid interfaces.

New article published in Angewandte Chemie
Changes in electrode surface chemistry under electrochemical conditions critically influence electrocatalytic performance. In this communication, in-situ electrochemical X-ray photoelectron spectroscopy was employed to monitor the surface state of tungsten carbide (WC) powder electrodes during the hydrogen evolution reaction (HER) and at oxidative potentials. This study was led by Julia Kunze-Liebhäuser (University of Innsbruck).

Perspective article published in ACS Nano
A new perspective article has been published in ACS Nano introducing the simultaneous operation of electrochemical scanning tunneling microscopy and force microscopy using a qPlus sensor, highlighting its future potential to provide high precision, enhanced flexibility and versatility, particularly as a multimodal approach to interface characterization. This work was published in collaboration with Franz Giessibl (University of Regensburg) and Julia Kunze-Liebhäuser (University of Innsbruck).
