How does governing work today, and how does society handle pressing challenges in ways that are democratic, effective, fair, peaceful, and sustainable?

Snelle en goedkope chips die extreem kleine hoeveelheden vloeistof (microfluïden) analyseren vormen de kern van gepersonaliseerde gezondheidszorg. Maar het ‘laboratorium op een chip’ is nog niet effectief genoeg. Dr. Paul Vulto en zijn onderzoeksteam ontwikkelden een techniek die het gebruik van microfluïdische…

This dissertation consists of two parts, with the common theme

In this thesis, we developed new ways to use a technique called electroextraction (EE) to extract charged molecules from one liquid into another using an electric field.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

Het Leiden Advocacy Project on Plastic (LAPP) is een pro bono initiatief aangaande juridische vraagstukken omtrent plastic. LAPP is opgericht om het toenemende probleem van plasticvervuiling aan te pakken en onderzoek te doen naar juridische kwesties gerelateerd hieraan. Studenten werken hierbij als…

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

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

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.

Op vrijdag 23 april verscheen Jorrit Rijpma voor de Working Group on Frontex Scrutiny van het Europees Parlement. Deze werkgroep is opgericht door de Commissie burgerlijke vrijheden, justitie en binnenlandse zaken (LIBE) van het Europees Parlement, als reactie op de beschuldigingen van serieuze schendingen…

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

Een nieuw artikel van Dr. Helen Pluut zal verschijnen in European Journal of Work and Organizational Psychology. Het artikel, dat samen met Marion Büttgen en Jan Ullrich van de Universiteit van Hohenheim is geschreven, heeft implicaties voor organisaties die een duaal laddersysteem hanteren. Zulke systemen…

In this thesis we study bistable reaction-diffusion equations on lattice domains.

This thesis investigates opinion dynamics on random graphs through the lens of the voter model, a classical interacting particle system used to describe how consensus emerges in networks.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

The dissertation describes TEM experiments on heterogeneous catalysts.

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

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

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Sinds april 2019 heeft de Faculteit der Sociale Wetenschappen er een nieuwe locatie bij voor haar onderzoek. Het Levelgebouw (direct naast Leiden Centraal) ontvangt proefpersonen in 3 gloednieuwe laboratoria. Psycholoog Mariska Kret vertelt enthousiast over de nieuwe mogelijkheden voor haar onderzoe…

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

Seizoen 2 van de Leiden Psychology Podcast is begonnen en we trappen af met een speciale Q&A met onze nieuwe hosts Aziza en Priya. In deze aflevering krijg je de kans om hen beter te leren kennen.

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…
