To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

Inspired by natural photosynthesis, perovskite-based photoelectrochemical (PEC) systems are being developed for artificial photosynthesis, aiming to enhance solar-to-hydrogen conversion for green energy.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

This thesis describes a study from both a theoreticaL and an experimental point of view.

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

Our current research focusses on the exploration of the Universe using the neutrino. This neutral, almost massless and only weakly interacting particle can open a window to the distant Universe and also dense regions from which photons cannot escape.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

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…

Solar energy harnessed by plants and algae has great potential to be converted into biofuels for future generations.

An Integrative Approach to the Hominin Record

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

“JARAK: the commoditization of an alternative biofuel crop in Indonesia” was a research program from 2010-2014 in which researchers from Indonesia and the Netherlands collaborated.

Green hydrogen is produced via a process called water electrolysis. During electrolysis water is split into oxygen and hydrogen.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

Just before Christmas, three talented scientists received good news: they are receiving a personal research grant from the Dutch Heart Foundation. Ilze Bot of the Leiden Academic Centre for Drug Research is one of those scientists. She will receive an Established Investigator grant of 650,000 euros.…

In a full lecture hall C1 the Faculty of Science started off the new academic year on Tuesday 5 September. The theme of the meeting was, just as it had been at the university's opening the day before, sustainability.

Leiden University encourages all its laboratories to obtain LEAF (Laboratory Efficiency Assessment Framework) accreditation.

The Faculty of Social and Behavioral Sciences is working hard on sustainability in its buildings and in its operations. In this way, we want to do our part to contribute to the university and faculty vision and goals, and to a healthy and sustainable campus.

After studying Life Science and Technology, David Louwrier conducted his PhD research at LUCAS about bioart and societal debates around biotechnology. Now that his PhD thesis has been submitted, David is developing educational material about the societal aspects of the biobased economy.

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

Una Europa launches regular seed funding calls. Leiden University and other Una Europa partners also often offer funding for projects involving Una Europa universities.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

The research that is united in the Liveable Planet programme, touches upon a wide range of aspects of human life. The goal is to deepen and expand the scope and to connect more researchers. The following case studies are examples of current research projects.

Are you engaged in society and interested in social issues? Study the Bachelor's in Public Administration in The Hague and learn how to analyse and solve complex challenges such as the housing crisis and energy transition, right in the administrative heart of the Netherlands.

Ludo Block wrote the eleventh chapter of the book 'Post-Crimea Shift in EU-Russia Relations: From Fostering Interdependence to Managing Vulnerabilities'. His chapter 'Business as Usual? Police Cooperation under a Cloud of Political Animosity' can be found on page 204 of the book.

From 20 June to 12 August 2011 a team from the Caribbean Research Group, Faculty of Archaeology, Leiden University and the St. Eustatius Centre for Archaeological Research (SECAR) under the direction of Dr. Grant Gilmore III, Dr. Menno Hoogland, Prof. Corinne Hofman and Dr. Alice Samson carried out…

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

We explore the particle physics and quantum world at the time of the big bang.

Leiden has a strong tradition in theoretical physics, thoroughly linked with experimental disciplines.

Are you eager to dive into a cutting-edge approach to innovation? Do you want to explore how frugality and frugal innovation can drive sustainability? And are you up for an international, real-life challenge? If so, this Leiden-Delft-Erasmus (LDE) minor on frugal innovation is for you!

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

Understanding how nature captures and transfers solar energy is essential both for elucidating biological photosynthesis and for guiding the design of artificial light-harvesting systems.

Fearing a trade-off with economic growth, countries feel discouraged to cut their CO2 emissions. But do the two really not go together? Environmental scientist Ranran Wang and her colleagues investigated the relationship between economic growth and CO2 emissions in 73 countries from 1970 to 2016. Wang:…

The Europe Hub network currently spans over 60 researchers across 4 faculties at Leiden University. We especially foster thematic interfaculty research collaborations on a wide variety of societal challenges facing Europe. Here, you can read more about the four core thematic areas.
