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.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

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.

Een geweldpleging zoals een mishandeling of kopschoppen zorgt voor ontzetting, pijn en verdriet. Dit geweld wordt vaak gezien als zinloos of beestachtig. Toch heeft geweld betekenis voor de daders, bepleit geweldonderzoeker Don Weenink in zijn oratie.

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…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

In this thesis, we extend the concept of null models as canonical ensembles of multi-graphs with given constraints and present new metrics able to characterize real-world layered systems based on their correlation patterns.

Op 11 november 2021 verdedigde Evelien Campfens het proefschrift 'Cross-border Claims to Cultural Objects'. Het promotieonderzoek is begeleid door prof.dr. N.J. Schrijver en prof.dr. W.J. Veraart (VU Amsterdam).

Symposium

On 4 and 5 November 2021 an ICOG-workshop will be held on the cognitive turn in history. It is possible to attend this workshop online. The participants of the workshop are cultural and intellectual historians of the pre-modern periods and/or of the historiography of academia from a long-term perspective,…

A century ago, it was unclear whether the stars in the sky were clustered in groups, or widely spread in the universe.

The Leiden University Centre for the Digital Humanities (LUCDH) invites applications from Leiden University staff and students for funding aimed at developing Digital Humanities activities.

Op haar tachtigste doet emeritus hoogleraararcheologie Corrie Bakels nog dagelijks onderzoek, na een leven lang pionieren. ‘Als enige vrouw werd ik flink uitgeprobeerd. Totdat ze ontdekten dat ik geen krimp gaf, dan was het over, zo van: jullie kunnen me wat. Dat werkt.’
