This thesis describes a study from both a theoreticaL and an experimental point of view.

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

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

Solar energy is used by photosynthetic organisms to drive energy required cellular processes. Is absorbed by two groups of pigments, located in the LHCs.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

Inspired by natural photosynthesis, perovskite-based photoelectrochemical (PEC) systems are being developed for artificial photosynthesis, aiming to enhance solar-to-hydrogen conversion for green energy.

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.

Als jong professional ben je volop in ontwikkeling. In je werk, maar ook thuis. Daarom bieden we je op donderdag 17 oktober bij de Universiteit Leiden in Den Haag een inspiratiemiddag aan. Met een presentatie over levensvragen zoals: wat ben ik en wie wil ik zijn? En workshops over vaardigheden die…

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…

Understanding how nature captures and transfers solar energy is essential both for elucidating biological photosynthesis and for guiding the design of artificial light-harvesting systems.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

The electrochemical hydrogenation reaction is an alternative approach for the transformation of unsaturated bonds without the use of flammable dihydrogen gas.
