This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

It has been a long-standing mystery how complex biological structures emerge from such seemingly uncoordinated building blocks as cells and tissues, in the presence of only minimal environmental guidance.

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

This book brings together phonologists working in different areas to explore key questions relating to phonological primitives, the basic building blocks that are at the heart of phonological structure and over which phonological computations are carried out.

In this thesis, we show how MRFM can usefully contribute to the field of condensed-matter.

Argumentation and rhetorics is the study of how we convince people verbally. In other words, what do people say and how do they say it?

Ecotox is located in an ambitious surrounding at the Leiden University. It is an initiative of both institutes Institute of Environmental Sciences (CML) and Institute of Biology Leiden (IBL).

Videos shared on social media have become important evidence to hold perpetrators of human rights violations accountable. What does this increased use of digital open source evidence mean for the quality of international human rights accountability? Through an innovative experimental design, this project…

Microwear and starch grain analysis on experimental and archaeological grinding tools from Central

You can get various forms of support for you active learning ambitions. Have you already reflected on your teaching practice and have a clear idea of your goals? Your first point of contact should then be your ICTO Coordinator & ICLON. Do you want to join the network of others involved in the topic?…

Humans and songbirds learn their vocalizations early in life by exposure to the vocalizations of adult conspecifics. Often, better learning outcomes are achieved with live, social, tutors than with audio-only exposure to vocalizations.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

Leiden University gives inquisitive students the opportunity to follow an extra programme or classes alongside their regular bachelor’s programme. These are called Honours College and Honours Classes.

This study presents the findings of a laboratory-based experiment testing hypothesised processes implicated in the prevention of violent radicalisation through counter-narratives. The central aims of the study were to contribute to counter-narrative theory, whilst highlighting the value of experimental…

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

On 14 January 2021, Joost Westerweel defended his thesis 'Lokale democratische innovatie'. The doctoral research was supervised by Prof. G. Boogaard and Prof. M.J. Cohen.

In Shimmering Images, Eliza Steinbock traces how cinema offers alternative ways to understand gender transitions through a specific aesthetics of change.

The Archaeology of Imperial Landscapes examines the transformation of rural landscapes and societies that formed the backbone of ancient empires in the Near East and Mediterranean. Through a comparative approach to archaeological data, it analyses the patterns of transformation in widely differing imperial…

The research in this thesis is focused on tomographic reconstruction based on two imaging modalities in electron microscopy.

The research group of Semonti Bhattacharyya at the Leiden Institute of Physics studies quantum transport measurements in Van der Waals heterostructures.

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

Viral hemorrhagic fever (VHF) is a group of acute diseases caused by highly infectious viruses including Ebola, Lassa, Dengue viruses. Its high mortality rate poses high risk to public health, however, studies on VHF have been hampered due to the non-availability of proper models and incomplete knowledge…

Lithic Biographies in the Neolithic and Bronze Age, Prof. Annelou van Gijn (2010)

In the first part of this thesis we study the geometry of folding patterns.

The position of writing within the domain of artistic academic research is not self-evident. In academia, standard practice is to use writing for the transfer of knowledge: it is a means of communication. In the practice of (nonlinguistic) artistic research, the outcome is also often contextualized…

Statistical considerations guide the design and implementation of the experiments that scientists perform. For instance, in a clinical trial about a the efficacy of a treatment, its effect in a certain minimum amount of patients has to be observed in order to make confident assertions about the efficacy…

Does “putting yourself in the migrant’s shoes” elicit more positive attitudes toward migration? Can perspective-taking – the active consideration of others’ mental states and subjective experiences – help undermine negative stereotypes and prejudice against migrants? We explore these questions in Ecuador,…

A new research line is the development of liquid biopsy fingerprints to predict early Alzheimer’s disease (AD) stage in human in readily accessible body fluids in human (in collaboration with: Dr. Geert-Jan Groeneveld, CHDR; Prof. Elga de Vries, Free University Medical Center; and others).

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…
