Samen met wetenschappers van over de hele wereld streeft de ENIGMA-Anxiety Werkgroep ernaar om meer inzicht te krijgen in de neurobiologische karakteristieken van angststoornissen.

Fundamenteel onderzoek leert ons hoe ons brein beslist om nog een dropje te eten in plaats van te gaan sporten. Een publieke voorlichtingscampagne over gezonde levensstijl heeft weinig impact op die beslissing, weet hoogleraar Algemene Psychologie Bernard Hommel. Hij weet wat wel werkt. Maar willen…

Ons onderzoek kent een stevige disciplinaire basis binnen een breed scala van wetenschapsgebieden.

Ook gewóón proza heeft stijl. Dat is de argumentatieve stelling die in de titel van dit proefschrift verborgen zit.

Hoe kan een CLIL-aanpak, met een focus op Disciplinary Literacies, het literatuuronderwijs van het LLA-programma in de bovenbouw van het tweetalig onderwijs (TTO) verbeteren?

Woorden kunnen, afhankelijk van wie ze waar en wanneer gebruikt, erg veel verschillende betekenissen hebben of zelfs het tegenovergestelde van hun woordenboekbetekenissen uitdrukken.

De onderzoeken aan het Leiden University Centre for Linguistics (LUCL) richten zich op taalvariatie en taaldiversiteit. Om zowel de maatschappelijke als de wetenschappelijke kennis over dit onderwerp te vergroten, zijn de onderzoeken ondergebracht in zes overkoepelende (en overlappende) onderzoeksprogramma’s.…

Sanne Kellij en collega's hebben 142 artikelen systematisch geëvalueerd, waarbij ze bewijs onderzochten voor drie hypothesen over de relatie tussen slachtofferschap en sociale informatieverwerking.

Het Brain and Education lab is een onderzoeksgroep van het Instituut Pedagogische Wetenschappen aan de Universiteit Leiden en maakt deel uit van het Leiden Institute for Brain and Cognition (LIBC). Ons onderzoek richt zich op de ontwikkeling van cognitieve processen die betrokken zijn bij leren en academische…

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

Despite the fact that gold nanoparticles (GNPs) are one of the most studied nanoparticles, there is still a necessity for new approaches allowing for effective protective coating to enable wider use of GNPs in biomedical applications.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

In the last decade, the redox interconversion between metal thiolate and disulfide compounds has been extensively investigated for copper, but not for other transition metal ions.

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Cardiovascular syndromes are the major cause of death in Western societies.

Planets are formed in disks of gas and dust around young stars.

This thesis explores the theoretical and observational properties of distant massive galaxies that harbour active black holes in their centres and shine brightly at radio wavelengths.

This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

Catharanthus roseus (Madagascar periwinkle) produces valuable monoterpenoid indole alkaloids (MIAs) such as vincristine and vinblastine, crucial for cancer treatment.

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

My PhD project studies how the temporally sequential Hox gene expression is regulated during head-tail patterning of the frog embryo.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

According to the amyloid cascade hypothesis, accumulation of beta-amyloid (Aβ) peptides initiates the pathological cascade in Alzheimer's disease (AD).

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

The AT-Hook Nuclear Localized 15 (AHL15) gene belongs to a plant-specific gene family of DNA-binding proteins. Overexpression of AHL15 in Arabidopsis thaliana delays developmental phase transitions whereas its loss of function causes a slight acceleration.

Nucleoid associated proteins maintain the architecture of the bacterial chromosome and regulate gene expression, hinting that their role as transcription factors may involve local three-dimensional chromosome re-modelling.

This thesis investigates reactive interfaces in surface science across three domains: heterogeneous catalysis, environmental nanoplastics, and two-dimensional materials.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

This work describes several studies into the electroreduction of carbon dioxide (CO2RR), both regarding mechanistical aspects and catalyst stability considerations. Mechanistic insights into carbon-carbon bond formation on a silver catalyst are described in Ch 2, were we find an acetaldehyde-like surface…
