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.

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.

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.

Microglia support the central and peripheral nervous system by forming the first line of defense against hazardous events. Microglia are increasingly acknowledged as critical players in neurodegenerative diseases, highlighting them as potential therapeutic targets.

Did the Jochids leave their mark on the Grand Duchy, taking into account that the Lithuanian state was one of the main successor states of the Great Horde in the 16thCentury?

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.

This thesis highlights the significant role of surface geometry and oxidation state in determining CO adsorption behavior on copper surfaces.
