We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

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…

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

Deze master specialisatie behandelt een breed scala aan wetenschappelijke onderwerpen, waaronder High Energy Physics and Particle Cosmology, Theoretical Physics of Life Processes en Condensed Matter Theory.

The LUGO Press is a student publication forum, rooted in academia and journalistic practices and published by the Leiden University Green Office.

Het moet er zijn, alleen kunnen we het niet zien: de raadselachtige donkere materie en donkere energie in het heelal. Henk Hoekstra is een van de vele kosmologen die dolgraag, willen weten waar deze substanties precies uit bestaan. Hij kreeg er een Europese onderzoekssubsidie van 1,3 miljoen euro vo…

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

De strategische richting van het GTGC stimuleringsgebied ligt bij een stuurgroep, bestaande uit zeven leden van vier faculteiten van de Universiteit Leiden. Onder voorzitterschap van de Leidse hoogleraar Global Transformations and Governance Challenges, behandelt de stuurgroep vragen rondom de algemene…

Europese burgers worden geconfronteerd met uitdagingen op het gebied van globalisering, migratie, technologische ontwikkelingen en klimaatverandering. Deze uitdagingen vergen het uiterste van onderlinge internationale en intergenerationele solidariteit, wat rechtstreeks betrekking heeft op de grondslagen…

In zijn proefschrift heeft Johannes Scholten onderzocht hoe volgens het jaarrekeningenrecht moet worden omgegaan met risico’s in verband met juridische geschillen en hoe hiermee in de verslagleggingspraktijk wordt omgegaan.

Light-Harvesting Complex II (LHCII) is responsible for light absorption and excitation energy transfer in plants and photosynthetic algae, while in high light it undergoes conformational changes by which it quenches excitations to prevent photodamage.

In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

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.

Photocatalysis has emerged as a powerful tool for enabling challenging transformations in organic synthesis. This thesis explores the development of several photocatalytic reactions designed to form carbon-heteroatom bonds from less-functionalized precursors.

This dissertation was to develop effective graphene-based nanofluidic devices by developing scalable fabrication methods and elucidating proton transport mechanisms.

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

In eight chapters, the thesis of Rafaël Vos covers the effect of temperature and pressure on the electrochemical CO2 reduction.

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

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

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

The work in this thesis demonstrates how to obtain an atomic-scale picture of a diverse set of complex surface structures observed using STM, under disparate conditions.
