Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

This thesis studies operator-algebraic aspects of subproduct systems, a generalization of product systems of Hilbert spaces.

A new type of tripodal squaramide-based supramolecular hydrogels is developed and studied.

Humans share meaning through language. Over time, repeated interactions have shaped languages into forms that match our cognitive preferences, making them structured, expressive, easy to learn, and ultimately, meaningful.

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

The aim of this thesis is to explore the use of Bioorthogonal Antigens to study the cross-presentation pathway.

The use of N fertilizers has increased worldwide in the past century. While this increased input of N has increased food productivity, it has also contributed to decreases in biodiversity, soil quality and environmental health, including increases in greenhouse gas emissions.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

This thesis develops a method for direction dependent calibration of the ionosphere in radio interferometric data.

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

Anthropogenic change is reshaping ecological systems, raising concerns about increasing transmission of infectious diseases. Among these, mosquito-borne diseases may be particularly sensitive to environmental change, as their transmission depends on vector populations.

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

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

Explaining treatment response variability between and within patients can support treatment and dosing optimization, to improve treatment of individual patients.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

Metabolomics is a powerful tool that can provide a comprehensive insight into the complexity of human biology and the pathophysiology of diseases. By analyzing the metabolome, which refers to the complete set of small (endogenous) molecules (with a mass <1500 Da) present within a given biological system,…

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

Cardiovascular diseases are still a major concern for the global health.

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

This work has described synthetic strategies towards well-defined structures resembling capsular polysaccharide (CPS) fragments, CPS mimics, teichoic acid (TA) fragments as well as a third-generation ring-closing tandem metathesis (RCM) linker to better exploit the potential of automated synthesis.

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

How did we come into existence? Are we alone? These questions have driven humans for centuries.

Kiemproject: Hoe kunnen metaforen bijdragen aan betere maatschappelijke betrokkenheid bij quantumwetenschap en -technologie, en welke factoren beïnvloeden de acceptatie of weerstand tegen metaforen bij zowel experts als leken?

Proparte is de Vereniging van hoogleraren van de Universiteit Leiden, echtgenoten en partners.

Om leraar te worden in het voortgezet onderwijs heb je een onderwijsbevoegdheid nodig. Deze kun je behalen via een (kop)opleiding aan het hbo of de universiteit. Welke route het best bij jou aansluit, hangt onder andere af van jouw hbo-diploma en wensen.

In deze tweejarige master zijn vakinhoudelijke verdieping en de lerarenopleiding gecombineerd in één programma.

De Commissie Studium Generale vormt mede de denktank van Studium Generale en wordt voorgezeten door dr. Pieter Barnhoorn.

How did colonial law work to turn people into property? This project argues that colonial ideas about households and domestic authority were critical to legal processes of enslavement in the early modern Dutch empire. Using colonial court records from Dutch Brazil, Suriname, and the Moluccas, the project…
