Artificial photosynthesis has recognised potential to produce green and sustainable fuels from earth-abundant resources such as water, carbon dioxide (CO2), and sunlight.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

Promotor: Bas Edixhoven, Promotor: Qing Liu

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Psychedelische drugs zoals paddo’s en LSD worden door de één omarmd, en door de ander gezien als levensgevaarlijk. Cognitief psycholoog Michiel van Elk dook in de wereld van de psychedelica en schreef er een opvallend nuchter boek over. ‘Zonder ervaring uit eerste hand vond ik mijn verhaal niet comp…

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

What is the current relevance of the ethics of counterterrorism and what is the added value of ethics support within the practice of counterterrorism?

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

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…

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

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.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…
