The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

This thesis provides an overview of the development of the Pair Configuration to Molecular Activity Coefficient (PAC-MAC) model.

Drie finalisten gingen de strijd met elkaar aan tijdens de jaarlijkse natuurkunde conferentie FYSICA, op 10 april 2015. Het project van Jacob 'A novel way to control STM-based manipulation: motion tracking and rapid molecular dynamics simulation' werd door de jury als beste beoordeeld.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

The space between the stars isn't simply a void; it also contains substances such as methanol and carbon dioxide. So far, chemical theories have been unable to explain how these substances originate under circumstances that should make it impossible. Fedor Goumans has been awarded a Veni subsidy to…

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.
