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…

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

The central aims of this project are to establish the shapes of the various urban hierarchies existing in the provinces of the Roman Empire and (especially) to use the quantitative properties of these hierarchies to shed new light on levels of economic integration.

My research project focuses on the development of a popular national agency in late nineteenth century Amsterdam and the question how ‘ordinary’ citizens imagined ‘the Netherlands’ through the experience and use of their urban surroundings.

Thermodynamics is one of the founding scientific pillars that has helped us better understand heat engines, biology, ecosystems, and even black holes. While it fundamentally describes large systems by examining the bulk behavior of their constituents, it is anchored in the statistical equivalence of…

What is the relationship between outcomes of dynamic testing and cognitive flexibility in young children?

The genomic DNA of every organism is organized and compacted in order to fit inside the cell. This is achieved by the joint action of numerous architectural proteins that aid in folding the genome. Genome folding is tightly interconnected with transcription, with genes in certain regions being silenced,…

Does a moving hybrid zone leave a genomic footprint?

This PhD research aims to trace the impact of the Arab conquest, both immediate and long-term, on the material and social organization of Central Asia from 651 to 821 through an “urban change” perspective in four cities: Merv, Paikent, Balkh and Samarkand.

Cell adhesion signaling

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

Making a dynamic substance stock model in order to conduct scenario analyses and make forecasts.

Sewer pipes are an essential infrastructure in modern society and their proper operation is important for public health. To keep sewer pipes operational as much as possible, periodical inspections for defects are performed.

Schemas are knowledge structures that allow us to make efficient judgments about the world without the cost of memorizing every detail of previous experiences. It has long been known that schemas can enhance long-term memory for related information.

When a star gets too close to a supermassive black hole, it is torn apart by strong tidal forces in a tidal disruption event (TDE).

This book explores the relationship between the production of new urban spaces and illiberal community-making in contemporary India. It is based on an ethnographic study in Noida, a city at the eastern fringe of the state of Uttar Pradesh, bordering national capital Delhi.

This minor focuses on how our thoughts, emotions and behaviour are influenced by other people, and how we influence other people.

Imagining Urban Complexity introduces passionate and critical perspectives on the link between the humanities and urban studies.

Health inequities, obesity among children, loneliness, performance stress among youngsters. What are the drivers behind such ‘wicked problems’ and how might they be related? This interdisciplinary minor offers you the possibility to work with societal partners to gain a deeper understanding of real-life…

Throughout all domains of life, from bacteria and archaea to eukaryotes, genomes adopt well-organized three-dimensional structures that can change in space and time to accommodate preferred transcriptional programs for environmental adaptation, the maintenance of cellular identity and differentiation…

Hybrid zones occur where two species meet and produce offspring (hybrids). Typically, hybrids show a considerable reduction in fitness. In this thesis two hybrid zones are treated.

Birds sing to be heard, but how do they cope with increasing noise levels? Which species persist in cities and why? And do they thrive or suffer in the urban soundscape?

Chromatin is an ubiquitous protein-DNA complex that forms the structural basis of DNA condensation in all eukaryotic organisms.

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

This work represents the final results of several years of research within the Maya region. It deals with the relations between architecture and urbanism with landscape and astronomy.

This dissertation shows that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof.

This project looks at the ways in which youth in southern Nigeria navigate their lives in a context of experiencing long-term socioeconomic uncertainty and political insecurity (duress).

Green infrastrucuture (GI) like urban farm and green roofs could provide many beneficial functions in cities. These include for example food production, flood prevention or increasing biodiversity. MultiGreen project aims at developing an integrated modelling tool to support…

The map application includes information from old and new buildings archaeological projects. This makes it possible to investigate whether water facilities (wells, cisterns) and waste facilities (cesspits, sewers) were the privilege of Leiden’s wealthy elite in the late 16th and 17th centuries or whether…

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.
