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.

The key characteristic of active matter is the motion of an emergent collection (such as a flock of birds), which is driven by the consumption of energy by its active components (i.e. individual birds).

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

In this thesis, we study different curved single crystals because of the diversity of surface structures across their curvature.

This thesis examines the impacts and challenges of water use of electric power system. This thesis found that there are large differences in water use of electricity technologies, with hydropower and thermal power being two large water users.

Sustainable energy from wind and solar is most readily available near the sea.

Producing green energy has become the main goal in our society in the search of reducing or eliminating the carbon emission from fossil fuels.

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

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.

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.

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.

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

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…

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.

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…

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…

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?

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 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.

This thesis focuses on the design and synthesis of activity-based probes and inhibitors targeting enzymes involved in the degradation of specific plant glycans.

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…

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

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…

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.

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.

De Computers, Privacy and Data Protection Conference (CPDP) is 's werelds toonaangevende multidisciplinaire evenement op het gebied van privacy en gegevensbescherming. CPDP brengt experts samen om de allernieuwste juridische, regelgevende, academische en technologische ontwikkelingen op dit gebied te…

Leidse natuurkundigen hebben een nieuwe techniek ontwikkeld om elektrische geleiding te visualiseren in materiaal van gestapelde individuele atoomlagen. Jaap Kautz en Johannes Jobst, die dit jaar de NeVacprijs ontvingen voor hun onderzoek, publiceerden in Nature’s Scientic Reports.

Met de huidige marktregels is het behoorlijk risicovol om in groene energie te investeren, en dat staat de strijd tegen klimaatverandering in de weg. Dat schrijft milieuwetenschapper Oscar Kraan in zijn proefschrift. Promotie op 25 april.

De energietransitie zal ook de bouw van een grote hoeveelheid energiecentrales met zich meebrengen. Zulke bouwprojecten kan op weerstand van omwonenden stuiten. Universitair docent Bríd Walsh onderzocht hoe een lokale gemeenschap het beste kan worden betrokken bij zo’n bouwproject.

Climate change, depletion of natural resources, loss of natural and cultural landscapes, and many other (ecological) sustainability challenges urge us to (re)evaluate human interaction with the natural world. This renewed environmental consciousness has invigorated not only scientists working on effects…
