The oxygen reduction reaction (ORR) plays a crucial role in electrochemical energy
conversion and storage devices such as alkaline fuel cells and metal–air batteries. These …

One of the main goals of surface science is the understanding of the elementary steps
occurring in catalytic reactions in the heterogeneous phase, in order to identify promoters …

Lateral confinement has been suggested as a possible mechanism for depopulation of
surface state levels and concomitant modification of metal surface related properties …

Surface states—the electronic states emerging as a solid material terminates at a surface—
are usually vulnerable to contaminations and defects. The robust topological surface state …

Quasiparticle interactions broaden spectral features at surfaces, which can be measured
using the scanning tunneling microscope (STM). We report the first study of lifetime effects …

Using density functional theory we study the effect of pre-adsorbed atoms on the
dissociation of N2 and the adsorption of N, N2, and CO on Ru (0001). We have done …

While the oxidation of CO has long been considered to be structure insensitive, nano-
assembled model catalysts consisting of size-selected metal clusters (Aun, Ptn, Pdn, and …

The modification of the Au (111) Shockley-type surface state by an adsorbed monolayer of
large π-conjugated molecules was investigated by high-resolution angle-resolved …

The wave functions of electronic surface states are localized near the surface of solids.
Therefore surface states are well suited to monitor the physical and chemical state of the …

Using low-temperature scanning tunnelling microscopy we have investigated confinement of
electronic surface states to hexagonal islands and other nanoscale structures on Ag (111) …
