If mankind wants to survive into the 22nd century, we will need to change the way we live drastically. The human impact on our planet is everywhere, we are changing the atmosphere, the oceans and the land, leading to global warming, climate change, loss of biodiversity and pervasive pollution. There…

In a typical glycosylation reaction, a donor is activated to form a (variety of) electrophilic species which can react with a nucleophilic acceptor, following a reaction mechanism having both SN1 and SN2 character.

The research described in this thesis focused on the use of bioorthogonal antigens to investigate immunological processes in antigen presenting cells. Bioorthogonal antigens are antigenic proteins produced through recombinant expression in a methionine auxotrophic E. coli strain.

In het schoolvak scheikunde is de concept-context benadering ingevoerd. Hans Vogelzang onderzocht of de Scrum-methodologie kan helpen bij het vormgeven van lessen met deze benadering.

Plant-microbe interaction resulted in different physio/chemical responses by host plant and interacting rhizobacteria.

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…

By placing food at the centre of investigation, this Minor explores current-day debates on political, environmental, economic and cultural change at both the local and global levels.

This thesis is largely an experimental study on the formation of solid-state simple and complex organic molecules in the H2O-rich and CO-rich ice phases of dense interstellar clouds and dark cores.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

What is the optimal design of sandy solutions for sustainable climate change adaption, from an ecological, biophysical and societal point of view?

Evaluating the environmental consequences of diet changes in the European Union.

A dense region of a gaseous and dusty cloud collapses to form a protostar surrounded by a disk and an envelope. This thesis uses both observations and models to study physical and chemical conditions of these protostellar systems which are likely where planets start to form.

Laboratory, observation and modeling work on the dissociation of polycyclic aromatic hydrocarbons in interstellar environments and the formation of new molecular species through the fragmentation process.

Description of 20th century changes in the Dutch flora: Description and interpretation (1999 - 2005)

With the rise of multi-drug resistant bacterial pathogens, the possibility of a post-antibiotic world is quickly becoming reality.

Op de eerste dag van jouw nieuwe baan heb je zweethanden, ben je nerveus en onzeker, maar een paar maanden later zijn die gevoelens al weer verdwenen. Je hebt jouw nieuw rol eigen gemaakt en je bent nu onderdeel van de organisatie. Het proces dat daar naar toe leidt heet

Advanced mass spectrometry of glycosphingolipids takes the central stage in this thesis. Investigations focus on characterization of glycosphingolipid metabolism in health and disease with emphasis to the detection and accurate quantitation of known and so far unknown glycosphingolipids and closely…

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.
