Surface plasmon lasers
Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

Bridging the gap between physics and chemistry in early stages of star formation
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.

On the origin of patterning in movable Latin type : Renaissance standardisation, systematisation, and unitisation of textura and roman type
This PhD-research is conducted to test the hypothesis that Gutenberg and consorts developed a standardised and even unitised system for the production of textura type, and that this system was extrapolated for the production of roman type in Renaissance Italy.

Searching for the sibling of the earth
Are there other planets like the earth, and will there also be life? Astronomers study planets around stars other than the sun, with the aim to find out what kind of gasses their atmospheres are made up with.

Bioorthogonal Labeling Tools to Study Pathogenic Intracellular Bacteria
In this thesis, bioorthogonal chemistry is combined with correlative light-electron microscopy to selectively label and study pathogenic intracellular bacteria within the host immune cell.
-
Cosmic particle acceleration by shocks and turbulence in merging galaxy clusters
In this thesis, I study the formation of large-scale structure and the physics of particle acceleration at large scales (~Mpc).
-
Magnetic imaging of spin waves and magnetic phase transitions with nitrogen-vacancy centers in diamond
The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

Assembling anisotropic colloidal building blocks
This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

PhDArts
Research in and through art is an inseparable part of the artistic or design practice of the researcher. Consequently, research-in-art (as opposed to research-about-art, such as art history) does not have a set goal or expected result, nor are there predetermined general procedures. The outcome of the…
