In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

This work is dedicated to interpreting in cohomological terms the special values of zeta functions of arithmetic schemes.

Obesity may alter how a person absorbs, distributes, metabolizes or excretes medication. This thesis describes how obesity affects drug levels in the blood for antimicrobial agents, such as ciprofloxacin and fluconazole.

There is an increasing amount of attention on EU and its Member States contributions to implementation of two landmark agreements: the Paris Climate Agreement and the UN Agenda 2030 with Sustainable Development Goals (SDGs). Absent from the current literature is an analysis of the political effect of…

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

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

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

The specialisation Science Communication and Society (SCS) concerns science communication in a broad sense. The program focuses on the link between science and society and covers knowledge and skills in the field of science communication.

Het The Hague Diplomacy Blog is het nieuwe blog van het The Hague Journal of Diplomacy (HJD), het onderzoeksvakblad voor de studie van diplomatie dat zijn thuis heeft bij ISGA.

Hydrocarbonylation of alkenes with carboxylic acids in synthesis of carboxylic acid anhydrides is relatively less explored. We herein present a study and optimization of a palladium-catalyzed hydrocarbonylation reaction of alkenes using carboxylic acids as the nucleophile, by which acid anhydrides can…

In this thesis we classify the pairs (p,G), where p is a prime number and G is a finite p-group possessing an intense automorphism, i.e. an automorphism that sends each subgroup of G to a G-conjugate, that is non-trivial and whose order is coprime to p.

Several single-stranded RNA viruses make use of Xrn1-resistant RNAs in their 3’ untranslated regions of their genome RNAs in order to increase their pathogenicity.

This Thesis focuses on the design and synthesis of ADP-ribosylated compounds that can be applied in biological studies.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

For optimization problems, it is often unclear how to choose the most appropriate optimization algorithm. As such, rigorous benchmarking practices are critical to ensure we can gain as much insight into the strengths and weaknesses of these types of algorithms.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

De Universiteit Leiden organiseerde haar eerste universiteitsbrede iftar, een bijeenkomst voor ontmoeting en dialoog over culturele en religieuze diversiteit. Dit initiatief werd mogelijk gemaakt door de Faculteit Sociale Wetenschappen, POPcorner-FSW, studentenvereniging SABR en POPcorner Den Haag.

Uitvoeringsambtenaren hebben enige beleidsvrijheid om naar eigen inzicht te handelen. Dat is meestal wenselijk, maar kan ook leiden tot uitwassen zoals etnisch profileren. Vaak wordt vergeten dat die beslissingen niet op zichzelf staan, maar ook veel te maken hebben met beleidskeuzes. Hoogleraar Maartje…
