Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

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.

Twenty years from now, the world population is estimated to be around 9 billion people (now 7.8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables, water and energy.…

Research at the THEOR group is comprised of the following research themes:

Twenty years from now, the world population is estimated to be around 8.7 billion people, compared to the current 7.3 billion. In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables,…

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

This book provides the answers, presenting clear insights into the current state of affairs and exploring future prospects.

Climate change and energy transition were an important theme of the Dutch provincial elections: how should we invest in new sources of energy? Leiden University conducts multidisciplinary research into renewable energy solutions. Read more about this in the ‘Renewable Energy’ research dossier.

Leiden University is in the process of transitioning from one energy source to another: fossil fuels have to make way for sustainable energy from sunlight, water and wind.

On Friday 10 July the Towards Biosolar Cells research programme was granted a budget of 25 million euros by the Dutch Government. The Ministry of Agriculture, Nature and Food Quality recommended the programme because it will contribute to green energy, improve food supplies and a create a more sustainable…

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

The present market regulations make it extremely risky to invest in green energy, and this is impeding the fight against climate change. This is what Oscar Kraan writes in his dissertation. PhD defence on 25 April.

In this thesis, dynamic testing principles were applied to examine young children's potential for learning. Our studies focused on the role of cognitive flexibility, to further increase our understanding of the cognitive processes involved in children's ability to learn from instruction and feedback,…

The E2CB programme has been launched to bring CO2 emissions to zero by 2050. The goal: to produce all raw materials for the chemical industry from sustainable sources. Professor of Electrochemistry Marc Koper is involved in the project.

Can dynamic testing provide us with insight in children’s potential for learning?

The subject of motherhood is interwoven with themes of survival, power and identity. It is also at the heart of any consideration of women’s writing. Conversations of Motherhood sensitively charts common themes, intersecting experiences and related topics within the cultural specificities of South African…

The solar system was formed approximately 4.56 billion years ago. Despite the numerous theories that have been developed over the years, the formation and evolution of the solar system still remain unclear.

Both Leon Jacobse and Thom Hersbach from Marc Koper's research group obtained their PhDs cum laude. They both investigated changes on the surface of a platinum electrode. Jacobse studied this at a positive voltage, Hersbach at a negative voltage. Platinum has the potential to convert renewable energy…

Unplugging equipment that's secretly guzzling electricity, putting the curtains behind the radiator and only using a water-saving showerhead. The students participating in the Student Energy Race are given tips that everyone who cares about the environment and their wallets should learn from.

The Institute of Environmental Sciences has carried out and participates in several projects that deal with the analysis of energy systems.

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.

Energy transition will entail the construction of large numbers of new energy installations. Such construction projects may meet with opposition from people living close by. Assistant Professor Bríd Walsh investigated how the local community can best take part in such projects.

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

The dissociation of CH4 into CH3 + H on a metal surface is the rate determining step in processes which produce hydrogen, such as steam reforming and catalytic partial oxidation. Ultimately, we want to study the dissociation of methane on Ni(111) and Pt(111) quantum mechanically while taking into account…

Governments are increasingly facilitating the roll-out of so-called “smart meters”, a technology for measuring energy consumption that are able to transmit and receive data using a form of electronic communication. However, implementation has been slow or even stalled.

The electrochemical reduction of a group of organic compounds on platinum is strongly dependent on the arrangement of the atoms in the platinum surface. Christoph Bondue, postdoc in Marc Koper's group, published this in Nature Catalysis on 4 March. The reduction of such compounds is an important process…

The research of our group is centered around dynamical systems, functional analysis and their interplay.

The transition from fossil fuels and the practical changes that this entails make many demands on citizens. Emma ter Mors, a psychologist and lecturer at Leiden University, is researching the factors that contribute to public perception and acceptance of new energy technologies.

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.
