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.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

This dissertation investigates the energy and material related impacts of the transition towards a low-carbon heating system in the Netherlands, in the context of its 2050 climate and circular economy policy goals.

Submissions are sought for a special issue with Frontiers in Political Science that explores the conceptual and practical aspects of a ‘just’ energy transition both within and beyond Europe. In particular, contributions to the theoretical and interdisciplinary foundations of just transitions, as well…

‘De prikkels in de wetenschap zijn net zo pervers als bij de banken’, vindt UMC-bestuurder en immunoloog Frank Miedema. Staan andere belangen goed wetenschappelijk onderzoek inderdaad in de weg? Op maandag 24 maart geeft prof. Miedema een openbare lezing over ‘Science in Transition’.

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.

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.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

Om windturbines en elektrische auto’s te bouwen, hebben we tonnen magneten nodig. Momenteel importeren we die voornamelijk uit China, waardoor Europa voor de energietransitie erg afhankelijk is van deze grootmacht. Daar moet verandering in komen, aldus Industrieel ecoloog René Kleijn. In het project…

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

Cryogenic electron microscopy (cryo-EM) is a powerful technique used to visualize the inside of cells and to study specific protein complexes. Within this thesis, I describe the use of various cryo-EM techniques to gain insight into the structural changes of the human pathogen, Vibrio cholerae, as it…

Geometric phases lead to a nontrivial interference result when an electron's different quantum mechanical paths choices encircle a magnetic coil in an Aharonov-Bohm experiment.

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

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…

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

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.

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.
