Interface Physics

The Interface Physics group uses various types of Scanning Probe Microscopy, Surface X-Ray Diffraction, and other techniques to investigate the structure and dynamic behavior of surfaces and interfaces. Most of the special-purpose instruments used in this research are home-built. Topics that we are working on at present include catalysis, nanotribology, deposition of graphene and other thin films,and nanobiology. Click on any of the items below to find out more.

NEWS / AGENDA

Joost Frenken on Radio 1 Langs de Lijn en Omstreken
Physicist Joost Frenken was interviewed on the radio show 'Langs de Lijn en Omstreken' (Radio 1) about the recent discovery of superconductive graphene. The one-atom-thick material was already known for its strength, flexibility, lightweight and good conductivity.

Recently, Frenken also appeared in De Volkskrant in an article on the same subject.

Rik Mom Awarded Michel Cantarel Grant

PhD student Rik Mom has been awarded the Michel Cantarel grant by the French Vacuum Society (SFV). At the European Conference on Surface Science he gave a prize-winning talk on the subject of his PhD research, making him one of five award winners. During his PhD research, Mom images catalysts at the atomic scale while they are operating in chemical reactions. Performing such studies under realistic conditions is essential. ‘Atomic scale studies on catalysts are often done in ultrahigh-vacuum and at low temperatures,’ he says. ‘This is not representative of real-life processes, which happen under pressures of 1 to 100 bar and at temperatures between 100 and 400 °C.’

To obtain results that are useful for real applications, Mom studies nanoparticle catalysts in chemical reactions at 1 bar and 250 °C, as he explained in his talk. In an effort to also improve the realism in the model catalyst that is used in the studies, he published a paper in The Journal of Physical Chemistry C on his successful attempt to control the preparation of complex, realistic model catalysts.
