The Role of Linker DNA in Chromatin Fibers
The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.
-
Nucleosome stacking in chromatin fibers probed with single-molecule force- and torque-spectroscopy
In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

Magnetic Resonance Force Microscopy and the Spin Bath
There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

Histone-DNA assemblies in archaea. Shaping the genome on the edge of life
All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

Spin-triplet supercurrents of odd and even parity in nanostructured devices
Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

Opgewonden DNA ontrafeld
De Leidse natuurkundige Maarten Kruithof heeft ontdekt hoe ons DNA zich telkens weer feilloos weet op te vouwen en ook weer weet te ontvouwen. In zijn proefschrift toonde hij aan dat het DNA opgevouwen wordt in één lange, zeer flexibele spiraalvorm.

Towards in-cell structural study of light-harvesting complexes : an investigation with MAS-NMR
Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.
-
Knots in plasma
A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

The spin evolution of accreting and radio pulsars in binary systems
Pulsars were first discovered in 1967 and since then the population has grown and expanded over several wavelengths.

On the random-matrix theory of Majorana fermions in topological superconductors
The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

High-throughput quantification and unambiguous identification for metabolomics
The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.
