Materials balances have been used in the recent past for the analysis of substance oriented environmental problems and the formulation of measures for environmental policy. In this study an integrated tool, based on the materials balance principle, has been developed for the analysis of both environmental…

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

The work presented in this thesis is based on ALMA surveys of protoplanetary disks in three star-forming regions: Lupus, OMC-2, and NGC 2024.

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…

This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

Irene Khan, expert op het gebied van mensenrechten, werpt een aantal vragen op: Wat kan men verstaan onder een ‘Culture of Justice’? Wie bepaalt wat 'Justice' is? Hoe realistisch is de bevordering van ‘Rule of Law’ en ‘Justice’ in landen waar sprake is van ernstige conflictsituaties en armoede?

The thesis explores how interstellar chemistry evolves as a function of time and changing physical architectures during the formation of stars.

In tien jaar tijd worden de gebouwen van de faculteit Geesteswetenschappen op het Witte Singel-Doelencomplex een voor een aangepakt. Het gerenoveerde P.J. Vethgebouw is in augustus 2017 in gebruik genomen. Begin 2020 werd de interne renovatie van het monumentale Arsenaal afgerond. In 2022 is gestart…

De Universiteit Leiden bouwt aan haar toekomst in Leiden. Daarom investeert de universiteit de komende jaren ruim 100 miljoen euro in de vernieuwing van de gebouwen van de Faculteit Geesteswetenschappen, aan de Witte Singel en de Doelenzijde. Met deze nieuwe Humanities Campus, nauw verbonden met…

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

De Universiteit Leiden werkt aan een groene, circulaire campus, met een forse energiereductie in 2050 als doel, zoals uitgewerkt in de in 2022 verschenen Routekaart energietransitie gebouwen.

The origin and evolution of galaxies are closely linked to many different physical phenomena.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

In this course, you will explore the organs involved in our food digestion and discover the common causes of abdominal and pelvic pain. The latest graphics and animations will give you new insights and understandings of this part of the body.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

Om de klimaatcrisis het hoofd te bieden, kan een bepaalde nederigheid van de mens ten aanzien van de natuur van groot belang zijn. Tegelijkertijd kan nederigheid ook politieke overheersing in de hand werken. Hoe kunnen mensen zich op een bescheidener manier tot de natuur verhouden zonder hun vrijheid…

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

In this thesis, we present new laboratory data of interstellar dust analogues.

The thesis describes experimental steps towards reduction of friction on the macroscopic scale by scenarios of thermo- and superlubricity well-known on the nanoscale.

Religion and ethnicity are inextricably linked in discourse within and about Central Asia. One common narrative suggests that as a result of differences between historically sedentary and nomadic populations, ethnic Tajiks and Uzbeks are naturally more religious and more likely to radicalise than their…
