Our research explores materials properties across a wide range of environments, from fundamental studies under ultrahigh vacuum to complex systems involving liquids and high-pressure gases. By combining scanning probe microscopy (STM/AFM) with chemically sensitive spectroscopic techniques (such as XPS and LEIS), we investigate structures with atomic precision. A custom-built setup enables the controlled dosing of ultrapure liquid water, allowing us to study material–water interactions under precisely defined conditions. We aim to deepen our understanding of natural processes and enhance the performance of materials in technological applications.
