The group’s origin is in the physics and chemical physics of solid surfaces. Heterogeneous catalysis, especially basic problems related to automotive emission cleaning and nanotechnology for sustainable energy are central themes. Hydrogen storage in nanoparticles and nanostructured fuel cell electrodes are new areas.
Biointerfaces (fundamental and applied research related to medical implants, biosensors and biochips, cell and tissue engineering,) is another large activity.
A growing activity with overlap with both of the above areas is optical properties of nanoparticles (metals and oxides) especially so called nanoparticle (local) surface plasmon resonances (LSPR), with relevance for biosensing, solar energy harvesting, and photocatalysis for air and water cleaning.
Nanostructures and nanotechnology are central in the whole group’s activity. For example both the catalysis program and the “photoactive nanostructures” program rely heavily on nanofabrication through a variety of lithographic and other methods. Of the latter colloidal lithography is a group specialty, allowing fast and cheap fabrication of nanoparticle arrays for several of the project areas above.
