This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

In this Thesis, novel charge induction mechanisms of ionic liquids are treated, tested and experimented on complex oxides, in particular cuprates.

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.

This thesis explores interfacial conductance and electric field-effects in LaAlO3/SrTiO3 heterostructures.

In this thesis, we have used numerical approaches to study the effects of translational symmetry breaking on strange metallic systems as realised by the holographic duality⁠.

Dit project gaat over de eigenschappen van kwantiteitsuitdrukkingen in verschillende talen vanuit het perspectief van hoe kwantiteit in het menselijk brein wordt weergegeven.

Dit doctoraatsproject onderzoekt voornamelijk op welke manier (d.w.z. serieel, parallel of op een andere manier) de parser het Mandarijn-Chinees verwerkt. Daarnaast wordt onderzocht of er specifieke taalkundige kenmerken zijn die de decodering van het Mandarijn-Chinees bepalen en die verschillen van…

Dit onderzoek gaat over de verschillen tussen luisteraars in de waarneming van prosodie.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

Protoplanetary disks are the gas and dust environments where planetary systems form around young stars. Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) this thesis analyses the gaseous molecular reservoir, using multiple tracers to resolve the 3D structure of protoplanetary…

Over geschiedenis van de sterrenkunde van radioastronomie tot exoplaneten, de revolutionaire ontwikkeling van de naoorlogse sterrenkunde.

Forming at the nodes of the Cosmic Web and growing hierarchically via mass accretion, galaxy clusters are the largest virialized halos in our universe, composed of dark matter (DM; ≥85%), ionized hot plasma in the intracluster medium (ICM; ≥10-15%), and galaxies (≥1-5%).

In the past decade many population studies have been performed with the Atacama Large Millimeter/submillimeter Array (ALMA) to understand the bulk properties of protoplanetary disks around young stars. These population studies mostly consisted of low mass stars, with relatively few of the disks around…

De Verenigde Naties hebben 11 februari uitgeroepen tot International Day of Women & Girls in Science. De Universiteit Leiden viert deze dag met een open publieksevenement met vrouwelijke topwetenschappers van haar bètafaculteit. Iedereen is welkom vanaf 13:30 uur in het Kamerlingh Onnesgebouw in Lei…

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

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.

This dissertation is an experimental study of laser-generated, atmospheric pressure, transient toroidal helium plasmas.

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

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…

Tin electrodeposition applications have rapidly evolved in the past 25 years.

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.
