This thesis discusses the physical and chemical processes than influence the composition of forming planets.

This thesis focuses on the X-ray spectral analysis of merging galaxy clusters and the plasma code development for future high-resolution X-ray spectroscopy observations.

In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

The focus of this thesis is how stars like our Sun and planets like Jupiter, Saturn, and Earth are formed.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

This thesis consists of three papers that are centered around the common theme of Hausdorff uo-Lebesgue topologies and convergence structures on vector lattices and on vector lattices and vector lattice algebras of order bounded operators.

Visualizing the internal structure is a crucial step in acquiring knowledge about the origin, state, and composition of cultural heritage artifacts. Among the most powerful techniques for exposing the interior of cultural heritage objects is computed tomography (CT), a technique that computationally…

Taal verbindt! Wij zijn er om u hierbij te helpen! Het Academisch Talencentrum (ATC) is het talencentrum van de Universiteit Leiden. Als oudste universitaire talencentrum in Nederland bieden wij taalonderwijs aan in een groot aantal talen, zowel voor beginners als gevorderden. Alle cursussen zijn met…

The main aim of this project is to reveal and unravel the invisible histories of the UN, transcending the dominant Western perspective to recover the historical agency of Global South actors. The research will investigate how the UN has both facilitated and limited their role in shaping global order…

Dankzij een succesvolle crowdfundingscampagne wordt er in het najaar een nieuwe module toegevoegd aan de vervolgsessie van de succesvolle Leidse Massive Online Open Course (MOOC) 'the Miracles of Human Language'; an Introduction to Linguistics. Ruim 240 donateurs hebben het doelbedrag van 10.000 euro…

Onderzoek naar taal levert een schat aan informatie over de mens: onze geschiedenis, verklaring van cultuurverschillen tot de manier waarop we leren. De universiteit deelt haar kennis en passie over het onderwerp op nieuwe manieren, via de MOOC ‘Miracles of Human Languages’ en het webdossier Taaldiv…

What is the environmental impact, the human health impact and the life cycle and production costs of the lab, pilot and commercial diffusion of nanowires and nanowire-based photovoltaic technologies?

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

We have conducted a full spectral line survey of the 3-13 micron region of two massive protostars, AFGL 2591 and AFGL 2136, for the first time at high spectral resolution.

It has now been well established that shocks and turbulent motions in the intra-cluster medium (ICM) generated through cluster mergers can produce large-scale synchrotron emission.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

This thesis systematically studies the physicochemical properties of non-planar, propeller-shaped, polycyclic aromatic hydrocarbons. The synthesis of several so-called propellerenes is described on a gram scale, using optimized procedures aimed at using less hazardous reagents and reducing the amount…

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Due to the almost complete disappearance of the archive of the Old Dutch West India Company (WIC, 1621-1674) not much is known about the ships and crews of this company. In this project we start the reconstruction of this basic information making use of new digital humanities techniques to extract this…

De relatie tussen christenen en moslims in het Midden-Oosten in de middeleeuwen wordt vaak getypeerd met termen als ‘conflict’ en ‘onderling geweld’. In zijn proefschrift zet Bas Snelders vraagtekens bij dat beeld. Analyse van kunst uit die periode laat namelijk zien dat beide gemeenschappen niet naast,…

Glycosidases (GHs) are enzymes responsible for the degradation of carbohydrates and play many roles in human health and pathophysiology. Often, abnormal levels of glycosidase activity are markedly linked to human pathologies.
