Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

Humans share meaning through language. Over time, repeated interactions have shaped languages into forms that match our cognitive preferences, making them structured, expressive, easy to learn, and ultimately, meaningful.

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

This dissertation is part of a broader research project that revolves around unraveling the evolution of balanced lethal systems.

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

The main goal of this thesis is to achieve advanced control of binding properties in bis-pyrrolic and macrocyclic pyrrolic receptors by light.

With an emphasis on developing novel miktoarm star polymers termed PeptoMiktoStars, this thesis leverages asymmetric polymeric polypept(o)ide frameworks to advance their effectiveness in delivering hydrophobic drugs and nucleic acids.

The aim of this thesis was to study phage infection in Streptomyces, focused on cell wall-deficient cells. Bacteriophages (or phages in short) attach to the cell wall of bacteria after which they replicate and lyse the host cell.

In this thesis we study products of linear error correcting codes.

Almost all bacteria are enveloped by a cell wall that provides cellular protection.

In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…

The work in this thesis describes the fundamental role of Lkb1 as a conductor of metabolism-related processes in zebrafish larvae.

In this thesis, we have studied cell images from two types of cells, including pollen grains and the immune cells, neutrophils. These images are captured using a bright field microscope and a confocal microscope.

A structural investigation of coiled coil peptides used as membrane fusogens, mimicing naturally occuring coiled-coil fusion proteins. Synthetic modifications have been made to alter lipid attachment, secondary structure and to insert photoactive azobenzene moieties for active control over coiled coil…

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

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…

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

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.

One of the major limitations in culturing complex tissues or organs is the lack of vascularization in the cultured tissue. Development of a functional capillary bed could overcome this problem.

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

Data Science (DS) and Artificial Intelligence (AI) are omni-present and have the potential to be incorporated in various fields. However, in order to live up to this expectation, a good understanding of the techniques, their implications and limitations is required. In this minor you develop insights…

Plastics are an intrinsic part of our society. Annually, 400Mt of plastics are produced of which roughly 40% is discarded within a year.

Search and conversational systems have become central to how people access information and perform tasks.

How should jurisdictions, both on the national and on the supra-national level, handle the interaction between public and private law where it regards the regulation of financial markets?

Sinds 1 december 2016 versterkt Theo Brinkel als bijzonder hoogleraar het Instituut Politieke Wetenschap van de Universiteit Leiden. Hij onderzoekt de verhouding tussen krijgsmachten, politiek en samenleving in Europa. Ook verzorgt hij onderwijs voor bachelor- en masterstudenten.

Confetti, steltenlopers en de nieuwe Einsteinfontein. Op maandag 2 september is het Gorlaeus Gebouw van de Faculteit Wiskunde en Natuurwetenschappen feestelijk geopend. Samen met Constantijn van Oranje knipte een aantal studenten het lint door. Decaan Jasper Knoester: ‘Het gebouw staat, nu is het aan…
