De cel is een zakje met water, en daarin opgelost spelen zich de levensprocessen af. Dat weet iedere bioloog, maar het klopt niet, vermoedt prof.dr. Rob Verpoorte: naast water lijken voorheen onbekende natuurlijke oplosmiddelen ook een rol te spelen. Dat zou de droogte- en koudebestendigheid van planten…

Welke chemische stoffen hebben planten tot hun beschikking en wat gebeurt er als ze deze inzetten tegen bacteriën of schimmels? Dat is wat promovendus Luis Salomé Abarca graag wil weten. Hij bestudeert hoe planten overleven en hun gebruik van chemische stoffen bij communicatie en afweer. Salomé Abarca…

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

Particles are omnipresent in biopharmaceutical products. In protein-based therapeutics such particles are generally associated with impurities, either derived from the drug product itself (e.g. protein aggregates), or from extrinsic contaminations (e.g. cellulose fibers).

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…

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

Although nanoparticles are extensively used in various applications like consumer products and have most probably entered the environment, little is known about the effects of these particles on living organisms.

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

Are there significant differences among the environmental impacts resulting form the production of Asian aquaculture commodities and what are the main causes for these?

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…

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.
