To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

Women Writing Mexico (WWM) is a network of women and men concerned with the human rights crisis in Mexico and more specifically, with the impact of structural forms of poverty, everyday violence, and discrimination based on gender, race, social class, and ethnicity, that particularly have an impact…

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.

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.

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

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

CMLCA is a software tool that supports the technical steps of the Life Cycle Assessment. The focus of the program is on advanced computational aspects of life cycle inventory calculations.

Neuraminidases are enzymes that cleave glycosidic linkages of sialic acid. These enzymes are involved in influenza infections as well as in many cellular processes in mammals and micro-organisms.

In 2005 groeven archeologen van de gemeente Leiden een 2700 jaar oude boomstamkano op. Deze boomstamkano wordt nu door wetenschappers van Material Culture Studies nagebouwd met behulp van replica's van ijzertijd-werktuigen. De wetenschappers willen zo onder meer beter inzicht krijgen in het bouwproc…

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…

Hoe geeft audiovisueel materiaal de identiteit van een volk vorm, als dat volk geen eigen land heeft en wordt onderdrukt? Bahar Simsek verdiepte zich in het effect van film op de Koerdische identiteit. Promotie op 4 mei.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

Hoe leefden mensen tijdens de nieuwe steentijd? Dankzij een NWO subsidie van 650.000 euro kan Annelou van Gijn en haar team daar de komende jaren in Vlaardingen uitgebreid onderzoek naar doen. Naar aanleiding van het nieuws over de subsidietoekenning schreven verschillende media over het onderzoek.

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

The key purpose of this project is to study tautological relations on the level of closed differential forms or even integral cochains (i.e. we don't take classes in cohomology).

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

This thesis aims to enhance our understanding of galaxies by testing theoretical models of galaxy formation against observations, particularly in the cases of extreme systems which have been found to have an excess of baryonic mass in their central regions, in the form of either supermassive black holes…
