surface modification and functionalization

Functionalization, enhancement and modification of catalyst material surfaces is achieved via MeV electron irradiation, plasma and UV-radiation treatment, as well as through chemical routes.

electrochemical energy applications

Prototype devices are assembled in house and the electrochemical performance is measured in a purpose build test station. Simple, controlled structures are evaluated for fundamental insight, as well as high performance, 3-dimensional nanostructures.
