Quantum critical metals at vanishing fermion flavor number.

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…

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 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.…

Clinical psychology is a discipline concerned with the application of psychological science to the assessment and treatment of mental disorders.

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…

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.

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.

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.

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…

In the specialisation Clinical Neuropsychology, part of the Master in Psychology, you will focus on fostering clinical and scientific skills based on a solid theoretical background as well as practical training in neuropsychology and (clinical) neuropsychological research.

The group is involved in training in areas of diagnostic skills, treatment/prevention/intervention, neuropsychological assessment, behavioral observations, clinical interviewing, knowledge of intellectual disability, autism, ADHD, psychosis and aggression.

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

The goal of pre-clinical development is to bridge the transition from lead compounds to clinical candidates by comprehensively characterizing safety, efficacy, and pharmacological properties. Once a lead compound demonstrates promising activity in disease models, it enters pre-clinical development where…

Research in the group Clinical Neurodevelopmental Sciences is focused on understanding and influencing developmental mechanisms in children and adolescents.

Medical technology has become an essential part of healthcare. Innovative treatment methods therefore require a new type of medical professional. Someone with medical and technical knowledge, who builds a bridge between technology and patient.

The Quantitative Clinical Pharmacology group is led by Prof. Dr. Catherijne Knibbe. Her research group aims to define how to adjust a drug dose in special patient populations such as (prematurely born) neonates or children, obese individuals or critically ill patients. Through combining the statistical…

The aim of our research program is to better understand the etiology and course of mood, anxiety and stress-related disorders, such as depression and posttraumatic stress disorder (PTSD). We investigate both the transdiagnostic mechanisms underlying these disorders and work on improving the treatments…

The group Clinical Neurodevelopmental Sciences has expertise in individual differences in child development, in particular the development of psychopathology, ranging from mild to severe neurodevelopmental disorders.

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,…

The Leiden Children’s Rights Clinic is a pilot initiative that advances the implementation of children's rights and offers research-based, legal and practical solutions to address the gap in knowledge and shortage of resources in the field of children’s rights.

The predication of the effect (efficiency and toxicity) of a drug in a patient is very important in (i) clinical decision support and (ii) the development of novel drug treatments. We apply our technology and methods to find biomarkers for key disease pathways and toxicity in clinical studies and in…

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.
