Nederland en China kunnen van elkaar leren slimmer om te gaan met afvalwater uit huishoudens en veeteelt. Leidse, Wageningse en Chinese wetenschappers gaan samen met betrokkenen werken aan haalbare oplossingen die milieu, gezondheid en economie vooruit helpen.

The global agri-food system plays a critical role in food security and environmental issues.

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).

Plant architecture has distinct forms in different plant species, but also within a species the finalarchitecture of a plant is determined by its gradual development and changes therein induced by environmental conditions during the plant’s life cycle.

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

Leidse natuurkundigen hebben een nieuwe techniek ontwikkeld om elektrische geleiding te visualiseren in materiaal van gestapelde individuele atoomlagen. Jaap Kautz en Johannes Jobst, die dit jaar de NeVacprijs ontvingen voor hun onderzoek, publiceerden in Nature’s Scientic Reports.

In het onderwijs bieden wij alle studenten de mogelijkheid om kennis te maken met duurzaamheidsthema’s en –vraagstukken, waar mogelijk aansluitend bij de inhoud van hun opleiding.

In this project innovative technology for photovoltaics cells is developed and analysis of ecological and health related risks are explicitly accounted for.

Where and how are critical materials currently used and how can this information be used to develop scenarios about their future demand.

In the first part of this thesis we study the geometry of folding patterns.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

A plasma is an ionized gas with very low electrical resistivity. As such, magnetic field lines are 'frozen in' and move with the fluid. Magnetic field lines that are linked, knotted and tangled, cannot be undone by the fluid motions.

Heterogeneous catalyzed processes are highly significant to the chemical industry. Dissociative chemisorption (DC) of molecules on surfaces is always considered as a step with a high degree of rate control for heterogeneous catalysis.

Het onderzoek binnen deze pijler richt zich op de systeemrisico's waarmee Europese samenlevingen worden geconfronteerd en die de kwaliteit van leven van Europese burgers beïnvloeden.

Microbial rhodopsins are photosensitive pigments implemented in the growth and adaptation of a large population of microorganisms.

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

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

Hoe dacht men tijdens de Renaissance over seks? Den Hartog neemt je mee op een tocht vol vervreemding én herkenning, en laat je met een nieuwe blik kijken naar seksuele opvattingen van toen en nu.

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.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

Tin electrodeposition applications have rapidly evolved in the past 25 years.

The research in this thesis is focused on tomographic reconstruction based on two imaging modalities in electron microscopy.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

Electron microscopy has become an extremely important techniquein a wide variety of elds.

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

Heterogeneous catalysis is one of the fundamental processes of modern life, being common in industrial refinery and hydrogen vehicles, all the way to the living cell. The dissociation of H2 on Cu(111) is an important benchmark system for studying heterogeneous catalysis, with a large and varied amount…

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.

Pectin is a plant cell wall polysaccharide made of mainly D-galacturonic acid (GA) subunits. The potency of the filamentous fungus Aspergillus niger to naturally secrete high amounts of pectinases to degrade pectin has been utilized for the industrial production of pectinases.

Na het afronden van de bacheloropleiding volgen verreweg de meeste studenten de masteropleiding. De Universiteit Leiden stimuleert studenten om na hun bacheloropleiding door te gaan met de masteropleiding.
