In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

Glycoconjugate vaccines are composed of microbial poly- or oligosaccharides covalently linked to a carrier protein.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Om de klimaatcrisis het hoofd te bieden, kan een bepaalde nederigheid van de mens ten aanzien van de natuur van groot belang zijn. Tegelijkertijd kan nederigheid ook politieke overheersing in de hand werken. Hoe kunnen mensen zich op een bescheidener manier tot de natuur verhouden zonder hun vrijheid…
