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.

Since its beginnings, Leiden University has been home to scholars with a broad and diverse expertise in the histories, languages, literatures and material cultures relevant to the study of Jews and Judaism from antiquity to modern times.

The project Multimedia Research and Documentation of African Oral Genres: Connecting Diasporas and Local Audiences (Director: D.Merolla) focuses on multimedia as technology that allows scholars to share documentation and scientific knowledge with the cultural owners of the collected oral genres.

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

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.

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.

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.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

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.

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Van een nietszeggend blok kunststof tot een geavanceerd onderdeel dat bijdraagt aan de energietransitie. De technici en wetenschappers van onze faculteit denken het tot in de details uit én maken het werkelijkheid. Ook dit bijzondere project laat zien dat ze niet zonder elkaar kunnen.

Van zwarte gaten tot kunstmatige intelligentie en van medicijnonderzoek tot data science: welkom in de fascinerende wereld van de Faculteit der Wiskunde en Natuurwetenschappen. Geregeld geven onze onderzoekers, studenten en gasten publieke lezingen over hun werk. U bent van harte uitgenodigd.

How to bring together different footprints into an integrated family and what are the synergies? What are the roles of inventory analysis and characterization in measuring individual footprints and how these affect a footprint family? How to benchmark environmental footprints against related planetary…

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…

What is the role of the rebound effect in achieving environmental savings from transport eco-innovation? Are traditional definitions of the rebound effect adequate in the context of transformative innovations and multidimensional environmental issues?

Wat heb je aan fundamentele wetenschap? Veel, zo bewijzen de sprekers tijdens Science Matters. Dit symposium werd op 18 maart 2016 gehouden ter ere van het tweehonderd jarig bestaan van de Faculteit der Wiskunde en Natuurwetenschappen.

The thesis is part of a bigger project, the HEPGAME (High Energy Physics Game). The main objective for HEPGAME is the utilization of AI solutions, particularly by using MCTS for simplification of HEP calculations.

1) Assess the trends in supply and production status of these critical minerals and mineral products worldwide and Europe’s dependence including on intermediate products such as permanent magnets, RE based super alloys, batteries, polishing compounds, phosphors, catalysts etc. 2) Trace the entire value…

In this thesis I describe the results of Pulsed Interleaved Excitation and Fluorescence (Cross) Correlation Spectroscopy (PIE-F(C)CS) combined with single-pair Förster Resonance Energy Transfer (spFRET) used to study dynamics in single nucleosomes, which depends on subtle differences in the length of…

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

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

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

The department of Industrial Ecology is dealing with research into the development of tools for decision making on sustainable production and consumption.

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

If mankind wants to survive into the 22nd century, we will need to change the way we live drastically. The human impact on our planet is everywhere, we are changing the atmosphere, the oceans and the land, leading to global warming, climate change, loss of biodiversity and pervasive pollution. There…

Nederland en China kunnen van elkaar leren slimmer om te gaan met afvalwater uit huishoudens en veeteelt. Leidse, Wageningse en Chinese wetenschappers gaan samen met betrokkenen werken aan haalbare oplossingen die milieu, gezondheid en economie vooruit helpen.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

Bio-energie met koolstofafvang en -opslag is een veelbelovende methode om CO2 uit de atmosfeer te halen en tegelijkertijd energie op te wekken. Maar deze methode is controversieel, omdat er veel grond en water voor nodig is.
