Molecular inheritance from cloud to disk: a story of complex organics and accretion shocks
Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

energy electron transmission through layered materials and chiral organic films
In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

The formation of complex organic molecules in dense clouds-Sweet results from laboratory
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.

'Q-wires': Synthesis, electrochemical properties and their application in electro-enzymology
An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

Exposure and health Assessment of Persistent Organic Pollutants (POPs) at e-waste recycling site among workers in the informal sector in Nigeria
Do e-waste workers display enhanced effects of adverse health effects due to informal e-waste processing in Nigeria? Is there a difference between the health outcomes of the exposed and the control groups? Are there difference in health effects within and between job groups (collectors, dismantlers,…

Synthetic, Physical and Computational Chemistry of Propeller-shaped Polycyclic Aromatic Hydrocarbons
This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

Low-temperature spectroscopic studies of single molecules in 3-D and on 2-D hosts
Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

Dark ice chemistry in interstellar clouds
This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

Laboratory studies of Water Ice in Space
Astronomical observations of cold regions in the universe show a rich inventory of ices. Part of these ices may end up on planets like our own, but in that journey they will be exposed to considerable amounts of radiation.

Thiosugars: reactivity, methodology and applications
Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

Impact of insect herbivory and microbial inoculants on the rhizosphere microbiome and volatilome
This thesis aims to investigate the effect of tripartite interaction between microbial inoculants, the plant, and herbivore insects on the rhizosphere microbiome and volatilome. We investigated the rhizosphere microbiome and volatilome of tomato plants exposed to insect herbivory and/or inoculated with…

Russische studies
Rusland is een spannend land. Jarenlang dachten we dat het land na het einde van de Koude Oorlog steeds meer ging lijken op ons in het Westen. Maar sinds de oorlog in Oekraïne is uitgebroken, weten we dat het zo eenvoudig niet ligt. Rusland is innig verbonden met Europa maar het gaat er allemaal toch…
