In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

Metal production is not only energy-intensive and a major source of greenhouse gas (GHG) emissions, but is also associated with other impacts affecting human health and ecosystems.

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

Galaxies are environments where gas coalesces, cools, and is converted into stars. However, it remains unclear the exact mechanisms through which galaxies acquire, redistribute and lose their gas.

Coordination chemistry is the chemistry of metal atoms

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

Hydrogen peroxide (H2O2) is an important bulk chemical that is used in various industrial processes. More than 95% of the H2O2 used in industry is made via the anthraquinone process during which a large amount of energy is going to waste.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

The confinement of molecular catalysts in metal-organic frameworks has the potential to lead to significant improvements in selectivity, long term activity and catalyst stability.

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.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

Humanity stands at a pivotal juncture, facing the dual challenge of environmental sustainability and rapid population growth, projected to exceed 11 billion by century’s end.

Over the past two centuries, socioeconomic development has improved material living standards but has also intensified environmental pressures, including climate change and biodiversity loss.

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

It is estimated that approximately 30% of all proteins require a metal to function. Investigating the relationship between metal-binding and peptide/protein folding allows us to uncover fundamental rules for creating metallo-peptides and proteins, which in turn leads to the creation of new structures,…

Multilingualism and Wellbeing is an innovative text that combines sociolinguistic, psychological and philosophical approaches to explore multilingualism as a source of wellbeing. It challenges the “monolingual bias” and the common assumption that multilingualism is solely driven by utilitarian, formal,…

The University’s Vision on Student Well-Being outlines how the University plans to promote student well-being in the coming years.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The interest of this thesis lies in spin transport in normal metals and superconducting half-metallic junctions.

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.

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

Do babies and toddlers thrive more in a noisy or quiet day care centre? Research by specialist in Education and Child Studies Claudia Werner shows that children feel most comfortable in an environment where there is a little noise. With this kind of research, the method of analysis is very important.…

How has landscape and land use changed in these two case studies since independence? What has caused these changes, whether anthropogenic or natural? How do local communities in the areas of study perceive these changes? How can community knowledge be integrated with mapping tools (GIS) to contribute…

The theme 'Health and well-being in a healthy society' is one of the focal points of the Faculty of Social and Behavioural Sciences (FSW). We are committed to promoting health and well-being for people of all ages.

The research area "Health and well-being in a healthy society" studies the institutional and behavioral factors that play a role in health and well-being for people of all ages.

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

Both good employer practices and good employee practices are open norms. These open norms can lead to uncertainty about what employers should focus on and what rights (and obligations) employees have in that respect. The objective of this study is to give substance to the norm of good employment practices…

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.
