Interface Science Department

Interface Science Department

Our department investigates the unique structural, electronic, vibrational and chemical properties of size- and shape-selected nanostructures and thin films and their interfaces with gas and liquid environments.

Understanding the interplay between the numerous factors determining the physico-chemical behavior of such systems is crucial for optimizing their efficiency for applications in catalysis and more specifically in energy conversion. To this end, advanced synthesis methods and in situ / operando surface/bulk-sensitive characterization techniques are being employed in our department for the fundamental understanding of catalysts “at work”.
