Can bacteria be engineered to convert methanol into valuable chemicals with high efficiency?

The thesis describes terrestrial field trials aimed to detect side-effects of pesticides within the framework of pesticide registration procedures. Field trials were developed using vascular plants Brassica napus and Poa annua, caterpillars Pieris brassicae and effects on decomposition were studied…

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

The development of new environmentally sound technologies is seen as a key route towards achieving sustainability.

The insights leading to the present project firstly manifested themselves in 2008, when I worked with field recordings on the basis of relatively well-established notions in music composition studies, such as ‘musical material’ and écriture. With hindsight, I understand the outcomes of those first experiments…

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

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

How can complexity science advance intelligence transformation?

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

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.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

In 2021, Leiden University will develop a new Sustainability Vision 2030. This vision for the future focuses on the primary tasks of the University: integration and visibility of sustainability in our education and research.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

Subproject of the NWO Smart Culture Grant research project 'The Critical Visitor'.

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

This thesis discusses the physical and chemical processes than influence the composition of forming planets.

This work represents the final results of several years of research within the Maya region. It deals with the relations between architecture and urbanism with landscape and astronomy.

For Leiden University’s operations, sustainability is an important topic, especially looking at the CO2-footprint, renewable energy and the greening of buildings.

This is a facility where research groups or small companies can apply for space if they need to culture human or animal cells.

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

Can Cyanobacteria be engineered to convert the greenhouse gas carbon dioxide into the valuable chemical isoprene?

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

Several buildings need to be demolished to make way for phase 2.

Leiden University is working on a green, circular campus, with a significant reduction in energy consumption by 2050 as its goal, as elaborated in the Route Map Energy Transition Buildings, published in 2022.

Imagine we could convert the greenhouse gas CO2 into synthetic fuels using sustainable energy. This would enable us to reduce the amount of CO2 and at the same time store wind and solar energy in an innovative way. Chemist Akansha Goyal (Leiden University) is conducting fundamental research to make…

De discussie over de sluiting van illegale schietbanen van Defensie, als gevolg van de stikstofwetgeving is ingewikkeld en omvat diverse juridische aspecten. Armin Cuyvers, hoogleraar Europeesrecht, bespreekt de zaak in BNR-Nieuwsradio.

Electrolysis is a technique that can be used to convert CO2 into fuels and other useful products. To do this efficiently and on a large scale, however, we need to understand exactly how electrolysis works. Professor Marc Koper is an expert in this field.

This project investigates the role of art in the public and academic debate on biosolar energy

In this thesis, we show that we can use Shimura’s CM theory to explicitly compute the Hilbert class field of any primitive quartic CM field.

Curious about how sustainability fits into our university's strategic plan, or how much energy and water we consume? Read about it here.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

This project, commissioned by DG Research and Innovation, aims to provide information for policies that lead to the creation and improvement of the conditions which will allow researchers and European industries to safely master the properties of nanomaterials and to innovate with nanotechnology.
