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.

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.

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…

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.

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.

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

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.

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…

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

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…

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…

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

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

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

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…

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…
