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

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

The redox-conversion reaction of metal-disulfide and metal-thiolate complexes are important, as they may shed light on electron-transfer reactions that often occur in Nature.

Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…

This thesis explores how bees and hoverflies are distributed across the Dutch landscape and how ecological and landscape factors shape their occurrence.

Empirical Legal Studies in Leiden focuste op het bouwen van een interdisciplinaire gemeenschap van rechtsgeleerden en sociale wetenschappers die samen juridische vraagstukken onderzochten op het snijpunt van recht en gedrag, waarbij diverse soorten methoden werden gebruikt.

This thesis consists of five chapters on how to construct prediction sets for different types of data and models in a parametric or nonparametric Bayesian paradigm.

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

Around the world, mindfulness has become big business. This course combines conventional scholarly inquiry from multiple disciplines with experiential learning to provide a responsible, comprehensive, and inclusive education about mindfulness as a contemporary phenomenon.

Deze opleiding biedt de mogelijkheid om onderzoek op moleculair, cellulair en organismaal niveau te verenigen, maar biedt ook de mogelijkheid om je te specialiseren op één van deze niveaus.

Sinds de oprichting is LUC een college voor onderwijsontwikkeling en experimentatie. In de missie van het college wordt LUC beschreven als "een plek van innovatie op het gebied van didactiek, curriculumontwerp en studentwelzijn." Deze visie wordt toegepast via een studentgerichte benadering in het onderwijs…

Fungal food spoilage often starts with a contamination with spores. Experimental data strongly indicate the existence of subpopulations of spores with different levels of resistance to preservation methods.

The sequence-dependence of biomolecular interactions involving nucleic acids and proteins is essential for numerous processes inside the cell. Insights into the underlying molecular mechanisms have been obtained using various biochemical and biophysical methods on two different levels — bulk and sin…

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.
