The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

Kunstmatige fotosynthese heeft als doel om via chemische processen zonne-energie om te zettn in brandstof. Semi-kunstmatige fotosynthese is een hybride aanpak waarbij chemische maar ook biotechnologische processen worden gebruikt. Wij hebben als doel om een hybride systeem te ontwikkelen met behulp…

This thesis describes the use of a combined approach of computational and experimental techniques to gain novel insights to understand the glycosylation reaction and its reactive intermediates.

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

This thesis has shed light on some of the ways in which the local electrolyte composition can differ from the bulk and how these changes in the local reaction environment can determine the activity and/or selectivity of two important electrocatalytic reactions, namely, electrochemical CO2 reduction…

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

A difficulty of studies on chemical kinetics are the reaction time scales and detection of their intermediates.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

Curved single crystals provide variable, but well-defined surface structures.

In this thesis we study bistable reaction-diffusion equations on lattice domains.

In this thesis, we study travelling waves in stochastic reaction-diffusion equations. We extend techniques from the deterministic theory for travelling waves to apply to the stochastic version, which allows us to compute the stochastic wave speed and shape, and draw conclusions on the stability of the…
