Materials with strongly correlated electrons show some of the most mysterious and exotic phases of quantum matter, such as unconventional superconductivity, quantum criticality and strange metal phase.

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

Het Leids Astronomisch Dispuut Frederik Kaiser is een vereniging die zich inzet voor de studenten die in Leiden sterrenkunde studeren. Daarnaast zijn ze ook erg betrokken bij de publieksactiviteiten in de Oude Sterrewacht en helpen ze bij de ontwikkeling en uitvoering van andere projecten in het geb…

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

De prof. A.E.J. Modderman Stichting is verbonden aan de Universiteit Leiden en beoogt bevordering van het onderzoek op het gebied van de strafrechtswetenschappen.

In most applications, electrocatalysts exhibit a large surface area to volume ratio, for example using nanoparticles.

In this thesis, we study different curved single crystals because of the diversity of surface structures across their curvature.

Cardiovascular diseases are a leading cause of death worldwide, and better models are urgently needed for disease progression studies and drug development.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

Microglia support the central and peripheral nervous system by forming the first line of defense against hazardous events. Microglia are increasingly acknowledged as critical players in neurodegenerative diseases, highlighting them as potential therapeutic targets.

This dissertation investigates the energy and material related impacts of the transition towards a low-carbon heating system in the Netherlands, in the context of its 2050 climate and circular economy policy goals.

In this dissertation non-parametric Bayesian methods are used in the application of robotic vision.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

Studeren aan de Universiteit Leiden voor een paar uur per week? Een cursus, of een aantal vakken volgen? Er zijn diverse mogelijkheden voor geïnteresseerden om kennis op te doen bij eenvan de Leidse opleidingen.

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

Stress komt veel voor in de huidige samenleving. Dit is zorgwekkend, aangezien onderzoek herhaaldelijk heeft aangetoond dat stress een negatieve invloed heeft op de lichamelijke gezondheid. Zo vergroot stress bijvoorbeeld de kans op hart- en vaatziekten.

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.
