Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

We have studied the impact of particle shape anisotropy, multivalent interactions and flexibility on systems of micron-sized colloidal particles.

Single-molecule spectroscopy has become a powerful method for using organic fluorescent molecules in numerous applications.

Promotores: Prof.dr. F.S. de Boer, Prof.dr. J.J.M.M. Rutten (Radboud Universiteit Nijmegen)

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

During my PhD research, I studied the photon statistics of light emitted by a microcavity that contains a single quantum dot (QD) on resonance.

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

In this thesis, the focus lies on studying glucocorticoid receptor dynamics in living cells with the aim of understanding how this transcription factor finds its DNA target sites to regulate transcription.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

Kidney transplantation is a major advance of modern medicine. This course will give you state of the art updates about what used to be an experimental, risky, and very limited treatment option more than 50 years ago and is now routinely performed in many countries worldwide.

Hoe denken burgers over overheidsschuld? Dit project onderzoekt de politieke grondslag van overheidsschuldcrises door te kijken naar de voorkeuren van burgers voor fiscaal beleid.

Bevolkingsgroei, economische expansie en het hieraan gerelateerd landgebruik leidt er aantoonbaar toe dat een toenemend aantal vogelsoorten uitsterft en dat de koolstofopslag in de natuur afneemt. Dit schrijft een internationaal team van wetenschappers van onder meer het Centrum voor Milieuwetenschappen…

The work described in this thesis focuses on the development of linear or cyclized peptide probes against protein N-methyltransferases to characterize their specific binding behavior, providing further binding details for inhibitory activity study.

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

In this top-rated course, you will learn how the European Union prepares and decides on policy, and how policy is transferred to member states and implemented by various authorities. It discusses the challenges of the European multi-level governance structure and the main causes of policy failure or…
