Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Het doel van het RAISE Onderzoek is om te onderzoeken hoe veerkrachtige mensen omgaan met stress. We kijken specifiek naar hoe belangrijke biologische systemen, zoals de HPA-as en het immuunsysteem, samenwerken met de hersenen en de sociale omgeving om veerkrachtig functioneren na moeilijkheden in de…

Sound is everywhere in the marine environment and hearing is therefore a very important for stimuli for fish. They use sound for orientation and communication, during migration, aggregation and spawning, but also for detection of prey and predators.

The parabolic Anderson model (PAM), which is the Cauchy problem for the heat equation with random potential. The PAM is a mathematical model that describes how mass (i.e. matter or energy) flows in a medium in the presence of a field of sources and sinks.

Sterrenkundige Ignas Snellen onderzoekt atmosferen van exoplaneten met als uiteindelijk doel aanwijzingen voor leven te vinden. Dat lukt steeds beter dankzij alsmaar slimmere meetmethoden van zijn onderzoeksgroep. ‘Binnen tien jaar wordt het echt spannend.’ Oratie 8 november.

Planeten in andere zonnestelsels bevatten waardevolle informatie over het ontstaan van planeten en leven. Promovenda Yapeng Zhang heeft hun atmosferen bestudeerd door te kijken naar hun kleinste onderdelen: isotopen. Met haar onderzoek hoopt ze te ontdekken wat ons eigen zonnestelsel uniek maakt.

Tijdens het bestuderen van zestien jaar aan meetgegevens van jonge sterren ontdekte de Leidse masterstudent Sam de Regt dat twee van die sterren nog gehuld waren in geboortewolken. Nog niet eerder bracht iemand deze twee sterren zo scherp in beeld. Hij publiceert zijn opschoonmethode en de nieuwe afbeeldingen…

Een internationaal team van sterrenkundigen waaronder ook Leidse wetenschappers publiceert het beeld van een jonge ster met een omringende stofschijf die nog steeds gevoerd wordt vanuit de omgeving. Het verschijnsel rond de ster SU Aur kan verklaren waarom zoveel exoplaneten niet netjes uitgelijnd zijn…

Astronoom Jos de Boer heeft in Nice de Chesneauprijs in ontvangst genomen voor zijn onderzoek naar zogeheten protoplanetaire schijven. De prijs wordt toegekend aan het beste sterrenkundige proefschrift op het gebied van hoge ruimtelijke resolutie. ‘Ik zie het als een goede kans om over mijn onderzoek…

Met een speciaal symposium in museum Boerhaave vierde ESO op maandag 26 september haar 60-jarig bestaan. Meer dan 100 wetenschappers, politici en mensen uit de industrie waren aanwezig om terug te kijken op samenwerkingen, mijlpalen en ontdekkingen. De Leidse astrochemicus Ewine van Dishoeck was één…

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

This thesis investigates how galaxies form and what diversifies the evolutionary histories of galaxies.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

The key purpose of this project is to study tautological relations on the level of closed differential forms or even integral cochains (i.e. we don't take classes in cohomology).

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

In the Schouwburgstraat, LUGO is currently redesigning the back-garden in order to increase biodiversity and make it a more beautiful space. Throughout October 2023 until March 2024, we will be making changes to the garden with our team of volunteers.

Early time-resolved experiments by Frauenfelder on the ensemble of the kinetic rebinding of CO to myoglobin molecules resulted in a stretched exponential relaxa-tion due to a very large spread of the reaction rates of individual molecules.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

The aim of the research presented in this thesis was to develop new methods forchallenging systems in liquid-state NMR using paramagnetic effects generated by thetwo-armed probe CLaNP-5.

The research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.

The intradermal administration route is attractive for vaccine delivery, because of the highly populated antigen-presenting cells in the skin. However, the skin’s main physical barrier, the stratum corneum, prevents vaccines from entering the skin.
