The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

Naar schatting bestaat de wereldbevolking over twintig jaar uit ongeveer 8,7 miljard mensen, terwijl dat aantal nu 7,3 miljard is. Deze groei, gecombineerd met de bijbehorende groei in consumptie en de verbeteringen in levensstandaarden, zal resulteren in een enorme groei in de vraag naar voedsel, verbruiksgoederen,…

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

Molecular materials have been a subject of interest in fundamental research and applications for decades, and have been studied as bulk crystals, (thin) films and as individual molecules, due to the large variety in their properties. This dissertation explores pentacene crystals near the two-dimensional…

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

Dit artikel beschrijft dat het gebruik van het concept van energierechtvaardigheid nieuw is, hoewel interpretaties al lang deel uitmaken van het energiebeleid.

In this Ph.D. thesis we study the interaction of low energy electrons with thin materials, namely layered materials (graphene, hexagonal boron nitride, molybdenum disulfide) and organic films. At these low energies the quantum mechanical wavelength of the electron wave function is in the order of a…

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

In this thesis, classes of strongly interacting quantum field theories, have been studied.

The global transition toward low-carbon energy systems and the rapid expansion of digital technologies, including artificial intelligence, are reshaping how modern societies produce, move, and process energy and information.

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

n this PhD thesis, the recombination of different atomic lattices in stacked 2D materials such as twisted bilayer graphene is studied. Using the different possibilities of Low-Energy Electron Microscopy (LEEM), the domain forming between the two atomic layers with small differences is studied.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

The work in this thesis describes the fundamental role of Lkb1 as a conductor of metabolism-related processes in zebrafish larvae.

Prof.dr. Gert Jan Kramer is bij de Faculteit Wiskunde en Natuurwetenschappen in deeltijd benoemd tot hoogleraar Sustainable Energy. Kramer is en blijft daarnaast manager Energy Futures bij Shell. Tot zijn aantreden in Leiden was Kramer hoogleraar bij de TU Eindhoven.

This thesis aims to address offshore wind energy (OWE)-related environmental impacts.

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

De Energie survival gids van prof. Jo Hermans is nu ook in het Engels beschikbaar en bovendien is het boek volledig geüpdated. De Energy Survival Guide is een compacte en betrouwbare bron van informatie voor iedereen die op zoek is naar adviezen over de toekomst van de wereldwijde energievoorziening…

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

In dit artikel onderzochten Annemiek de Looze en Eefje Cuppen empirisch of en hoe sociaal conflict leidt tot institutionele verandering.

This dissertation investigates the energy and material related impacts of the transition towards a low-carbon heating system in the Netherlands, in the context of its 2050 climate and circular economy policy goals.

Submissions are sought for a special issue with Frontiers in Political Science that explores the conceptual and practical aspects of a ‘just’ energy transition both within and beyond Europe. In particular, contributions to the theoretical and interdisciplinary foundations of just transitions, as well…

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

Op 17 april verdedigde Evert-Jan Govaers het proefschrift 'Ministers van Staat: onbekend en bemind; van podium naar de coulissen?'. Het promotieonderzoek is begeleid door Wim Voermans.

Het staats- en bestuursrecht geeft de regels, aan de hand waarvan maatschappelijke vraagstukken door de overheid worden opgelost.

De huidige en toekomstige quantumcomputers vormen dezelfde uitdaging als de laser in zijn begindagen. In theorie werd voorspeld dat de laser een bron van zeer speciaal, zeer krachtig licht zou zijn. Maar in die tijd waren er geen duidelijke toepassingen voor. Critici van het idee noemden het een probleem…

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

De master Staats- en bestuursrecht besteedt aandacht aan de wisselwerking tussen nationaal & Europees recht. Dit is een afstudeerrichting van de master Rechtsgeleerdheid.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

This thesis addresses the importance of a resilient supply of critical raw materials (CRM) for the global energy transition.

The focus of the dissertation

Metal production is not only energy-intensive and a major source of greenhouse gas (GHG) emissions, but is also associated with other impacts affecting human health and ecosystems.

Supply risks are not new. But the aggravation of power conflicts on the international stage coupled with global shifts towards energy transition and digitalization has triggered the next supply risk research era.
