Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

This thesis covers several aspects of quantum algorithms for near-term quantum computers and its applications to quantum chemistry and material science.

In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

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.

In this thesis we study quantum transport phenomena on the nanometer scale, in two classes of materials: topological insulators with induced superconductivity and graphene superlattices.

The disease acute myeloid leukemia (AML) is characterized by fast progression and low survival rates.

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

Transport inspectorates are looking for novel methods to identify dangerous behavior, ultimately to reduce risks associated to the movements of people and goods. We explore a data-driven approach to arrive at smart inspections of vehicles.

In de geest van ‘eenheid door verscheidenheid’ is ons doel het bevorderen van inzicht in en waardering voor het wonder dat dezelfde natuurkundige wetten en wiskundige concepten van toepassing zijn op de hele natuur, van de grootste tot de kleinste energie- en lengteschalen. Wij streven naar de toepassing…

Like a mixture of oil and water, lipid membranes separate into two liquid phases.

Waterdruppels zweven in een hete pan vanwege het zogenoemde Leidenfrost-effect. Nu hebben natuurkundigen een variatie ontdekt: het Elastische Leidenfrost-effect. Het verklaart waarom hydrogel balletjes op een hete plaat rondspringen en hoge piepgeluidjes maken. Publicatie in Nature Physics op 24 jul…

Hoe complexer het voorwerp, des te ingewikkelder het is om op te vouwen. Een ruimtevaartuig heeft al snel vele motortjes nodig om een instrument-arm in elkaar te vouwen en mensen hebben zelfs moeite met een wegenkaart. Natuurkundigen uit Leiden en Amsterdam hebben nu een structuur ontworpen die zichzelf…

The expedition commanded by Nicolas Baudin to Tenerife, Mauritius, Australia, Timor and South Africa in 1800-1804 is fully researched in regard to ornithology.

The project Multimedia Research and Documentation of African Oral Genres: Connecting Diasporas and Local Audiences (Director: D.Merolla) focuses on multimedia as technology that allows scholars to share documentation and scientific knowledge with the cultural owners of the collected oral genres.

Op 7 december 2021 verdedigde Georgina Kuipers het proefschrift 'Beschadigd vertrouwen'. Het promotieonderzoek is begeleid door prof.mr. W. den Ouden en prof.dr. M.A. van der Steen (EUR).

Op 11 november 2021 verdedigde Evelien Campfens het proefschrift 'Cross-border Claims to Cultural Objects'. Het promotieonderzoek is begeleid door prof.dr. N.J. Schrijver en prof.dr. W.J. Veraart (VU Amsterdam).

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

Galaxies in the local Universe fall into two main categories of spirals and ellipticals. In this Thesis, we explore the structural evolution of galaxies into this bimodal distribution.

Scattering of light in the presence of nano-structured materials, i.e. with features in the order of the wavelength of the light or smaller, reveals details of how light interacts with matter at the nanoscale.

This thesis describes a study from both a theoreticaL and an experimental point of view.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

Majorana fermions in superconductors are the subgap quasiparticle excitations that are their own antiparticles.

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).
