The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

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

The cellular metabolism of immune cells constitutes an important part of their proper function and activation. Using T cells as an example, this phenomenon is highlighted by the metabolic reprogramming that occurs in these cells upon activation.

This thesis presents the first synthetic peptides ADP-ribosylated on serine, threonine, tyrosine, arginine and cysteine.

Cyclic peptides are investigated as a platform to induce different orientations between various ligands.

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…

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.

Despite being the second largest transmembrane protein family after GPCRs, the SLC superfamily has only gained significant attention in early drug development over the past decade.

This thesis advance our understanding and the application of molecular catalysts relevant to the reduction of oxygen as well as reduction of nitrite.

Ethische toetsing gaat onder andere over de bescherming van de onderzoeksparticipanten en onderzoekers en die bescherming is gelijk ongeacht wie het onderzoek uitvoert. Pedagogische Wetenschappen onderwijst studenten in de ethische aspecten van onderzoek doen.

The main goal of the research described in this thesis was the development of new photoactivated chemotherapy (PACT) ruthenium(II) complexes bearing a non-toxic photolabile ligand.

Tielens werkt momenteel als senior onderzoeker bij Ames in Moffett Field, Californië. Ames is een onderdeel van NASA. Daarnaast…

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

In this project of the Center for Public Values & Ethics (CPVE) ongoing research is conducted on the history of advice to Dutch central government by so-called State committees from 1814 to 2014. State committees have been installed by Dutch central government since 1814 to provide expert advice, research…

This thesis describes the use of an activity-based proteomics method to study the endocannabinoid system.

In samenwerking hebben eLaw en het Design for Values Institute van de TU Delft een onderzoeksproject afgerond over “Artificiële Intelligentie en Ethiek bij de Nederlandse Politie”. Hierin zijn een whitepaper over verantwoord gebruik van AI bij de politie en een langetermijn strategie opgeleverd.

De afdeling Beleid en Innovatie van het Instituut Bestuurskunde richt zich op het vormgeven, implementeren en evalueren van beleid met innovatieve benaderingen. Ons doel is om complexe maatschappelijke uitdagingen aan te pakken door technologische vooruitgang en creatieve beleidsinstrumenten te onde…

FAIR-ASSESS wordt bijgestaan door een wetenschappelijke raad bestaande uit interne leden verbonden aan Universiteit Leiden en externe leden van buiten de universiteit met expertise in het veld.

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

This thesis describes the use of bioorthogonal proteins in immunological settings. It provides an introduction towards the field of protein modification, which was used throughout the thesis for the expression of proteins containing unnatural amino acids.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.

Pseudomonas Aeruginosa is a Gram-negative bacterium which can form biofilms, increasing its resistance against antibiotics and the host immune system. Polysaccharides are an integral part of this biofilm, one of these polysaccharides is called Psl. PslG is a glycosidase, able to cleave this polysaccharide,…

The adenosine receptors are proteins that reside in the extracellular membranes of cells. Activation of adenosine receptors plays a role in many physiological and pathological processes, such as immune responses and cancers.

Understanding how chemical complexity emerges during star formation requires connecting molecular material preserved in interstellar ices with that observed in the gas phase after protostellar heating begins.
