Even though more than 4000 extra-solar planets are known today, only a small fraction of these has been captured in an image. To better understand the planet formation mechanisms in solar-like environments we started the Young Suns Exoplanet Survey (YSES).

‘Een particuliere donatie voor je onderzoek, dat is heel bijzonder’, vindt de Leidse psycholoog Femke Nijboer. Een deel van de opbrengst van het boek ‘Donkere wolken’ schenkt schrijver en ervaringsdeskundige Sun Mi Venema voor onderzoek naar het locked-in syndroom. Een gesprek over een cheque van Venema…

The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

Faciliteiten waar LIBC leden gebruik van kunnen maken (in het Engels):

All crested and marbled newts (the genus Triturus) suffer from an unusual genetic abnormality, called a balanced lethal system, that kills exactly half of their offspring. How can a trait so disadvantageous have survived millions of years of natural selection?

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

GLOBOX is a spatially differentiated multimedia fate, exposure and effect model. It is used for the calculation of spatially differentiated LCA characterisation factors on a global scale.

This dissertation consists of two parts, with the common theme

Europese burgers worden geconfronteerd met uitdagingen op het gebied van globalisering, migratie, technologische ontwikkelingen en klimaatverandering. Deze uitdagingen vergen het uiterste van onderlinge internationale en intergenerationele solidariteit, wat rechtstreeks betrekking heeft op de grondslagen…

During the summer, we organize a summer school for researchers who want to learn about communicating science to diverse audiences. The summer school is aimed at researchers in any career stage who are new to science communication. The Summer School is open for all disciplines in science, including social…

De eerste index om de veiligheid, duurzaamheid en circulariteit van producten te meten, waarmee ze het EU-kader (SSbD) operationaliseren.

The main topic of this PhD thesis is the Arakelov ray class group of a number field, an algebraic object that contains both the ideal class group structure and the unit group structure.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

In this thesis chemical and physical processes in the ice mantles on interstellar dust grains are studied.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

N-acylethanolamines (NAEs), including N-arachidonoylethanolamine (anandamide, AEA), N-palmitoylethanolamine (PEA) and N-oleoylethanolamine (OEA), are signaling lipids that play an important role in different physiological process.

This thesis concerns the relation bettween the good reduction of Shimura varieties and the associated loop groups.

This thesis comprises the development of reproducible synthesis procedures for two-dimensional materials (composed of boron, nitrogen and carbon) on different metallic surfaces.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

Dit artikel biedt een systematisch literatuuronderzoek van de belangrijkste principes, normen en strategieën van Security by Design en Privacy by Design.

Hoe worden nachtruimtes verbeeld, geproduceerd, ervaren en verteld door migrantengemeenschappen in Europa? Dit onderzoeksproject onderzoekt deze vraag in acht Europese steden: Aarhus, Amsterdam, Berlijn, Cork, Galway, Lissabon, Londen en Rotterdam.

The majority (80%) of e-waste generated globally are recycled informally in developing countries.

In 2009-2010 ontstond in het westerse discours het idee van een meer ‘assertief’ China, een opvatting die China krachtig van de hand wijst. Niettemin is, vooral sinds Xi Jinping in 2012 aan de macht kwam, duidelijk dat China zijn lang gehanteerde buitenlandse beleidsdoctrine van ‘een lage profilering…

What holds people together and what makes them willing to fit within larger political structures? Our project examines this question in the practices of dynastic rulership in Eurasia ca. 1300-1800.

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

A New Technology-Based Firm (NTBF) is a significant enabler of job creation and a driver of the economy through stimulating innovation.

This book explores the spiritual potential of faith, mysticism and transcendence in answer to the dangers of a mythologised state and the sacro-sanctification of (liberal) democracy and its rule of law.

Cancer is considered the silent pandemic of the 21st century and the second leading cause of death worldwide.

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…

The soil-dwelling, filamentous bacteria of the genus Streptomyces are renowned for their production of useful secondary metabolites including antibiotics. The work described in this thesis provides new insights on the role and regulation of antibiotic production and resistance in these bacteria.

Regeneration is the ability of an organism to restore damaged or lost tissue with a functional replacement, and without scarring. Many lizards can regenerate their tails.

For centuries astronomers studied the Universe by collecting light. Nowadays, we are living in times of great technological advancements, which allow us to explore our Universe in a new way - though gravitational wave radiation.

Throughout the history of computer science, a major challenge has been how to assert that software is free of bugs and works as intended. Software bugs can lead to serious negative impacts on any software system. Throughout the main body of the thesis, we implemented a series of studies on exploring…
