The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

De onstuitbare opmars van de N.V. Zuid-Korea

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

Zo’n beetje alles over Charles Darwin is inmiddels wel geschreven of gezegd. Toch wist Norbert Peeters – samen met Tessa van Dijk – alsnog een origineel boek te schrijven over de grote Engelse geleerde. In aanloop naar Darwindag (12 februari) vertelt hij erover.

Bij Leiden University College The Hague staan Global Challenges centraal. Global Challenges zijn de grote, maatschappelijke uitdagingen van de 21ste eeuw waar we gezamenlijk een oplossing voor moeten vinden, zoals klimaatverandering, armoede, ongelijkheid, vrede en recht. Onze opleiding is opgesplitst…

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Jan van den Berg heeft zij proefschrift op 8 november 2018 verdedigd.

The CC chemokine receptor 2 (CCR2), a member of the G protein-coupled receptor (GPCR) superfamily, is widely involved in autoimmune and inflammatory diseases. However, no drugs for this receptor have made it to the pharmaceutical market yet.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

By growing in a soil plants change the biotic and abiotic properties of the soil in which they grow.

Self-assembly offers a promising route to create complex structures and materials using simple building blocks. Through, colloidal self-assembly, we can understand the governing principles of the self-assembly process and unlock its potential in diverse applications in materials science, photonics and…

Of all the mass in our Universe, 80% is thought to consist of a hypothetical and invisible substance called dark matter (DM).

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

The stratum corneum is the outermost skin layer and consists of dead cells embedded in a lipid matrix.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

In this thesis, we present new laboratory data of interstellar dust analogues.

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.
