Physicist Daniël Geelen has developed a new microscope that uses low-energy electrons. Those are less harmful to biological and organic materials. Geelen defends his PhD thesis on May 31st.

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

Het CPL biedt opleidingen voor hogeropgeleide professionals: starters, ervaren professionals en leidinggevenden.

Submissions are sought for a special issue with Frontiers in Political Science that explores the conceptual and practical aspects of a ‘just’ energy transition both within and beyond Europe. In particular, contributions to the theoretical and interdisciplinary foundations of just transitions, as well…

Even with state-of-the-art technology, it is almost impossible to see: a cosmic neutrino. Yet scientists have managed to image this particle with a deep-sea telescope. And that could help to better understand our universe. Leiden particle physicists collaborated on this ambitious project, published…

Recently the WTO panel report on India – Solar Cells (DS 456) was distributed. Under India’s Jawaharlal Nehru National Solar Mission (JNNSM), solar power developers were required to use certain types of solar cells and modules manufactured in India for power generation projects in order to ultimately…

Understanding the water use of power production is an important step to both a sustainable energy transition and an improved understanding of water conservation measures. However, there are large differences across the literature that currently present barriers to decision making.

Two things are needed to produce fuel from sunlight: an antenna that harvests light, and a light-driven catalyst. The most efficient antennae contain bacteria. An international team headed by Huub de Groot imitated them and discovered how they function.

For the first time, scientists have traced back a high-energy neutrino to its source in space. It was produced by a so-called blazar—a supermassive black hole. Researchers from neutrino detector IceCube report this in Science. ‘This is a milestone for neutrino science,’ says physicist Dorothea Samtleben…

Research reveals how boys respond to harassment awareness training and why they often fail to see street harassment as 'their' problem.

At the largest scales, two ingredients dictate the distribution of matter in the Universe. The first is dark matter, acting as an invisible scaffolding held together by gravitational forces.

The gas prices now exceed 300 euros per megawatt hour – a record. The transition from fossil (natural gas, coal, oil) to renewable energy is needed and soon. But how do you get a society (and its citizens) to switch to sustainable energy?

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

HomininSpace is an agent based modelling and simulation system in which fluctuating carrying capacity is the key attractor for hominin dispersal. A parameterized and spatially explicit reconstructed palaeo-environment models available energy in the form of secondary biomass using reconstructed climate…

A radical reduction in the amount of meat, dairy and other products sourced from animals is possible in the coming decades, as people turn to an increasing variety of alternatives. This would unlock vast amounts of land that we could use to produce energy and remove carbon from the atmosphere. Leiden…

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

Exponential population growth and rapid urbanisation are prompting the development of gigantic African metropolises that must be supplied with resources such as food, water and energy. This creates economic opportunities, drives migration and presents political challenges. Researchers from Leiden combine…

Africa is seen as a potential leader in green hydrogen production for domestic consumption, export and greening industry. One key barrier to realising this potential is the mismatch of skills between those required by industry and the capability of local workforces.

CML-researcher Rene Kleijn has spoken about metals scarcity in relation to the energy transition in a new Dutch popular scientific TV show called

Un)timely Crises explores how ‘crisis’—as a narrative, concept, grammar, and experience—structures time and space. This collectively written volume extends Bakhtin’s ‘chronotope’ to challenge mobilizations of crisis within neoliberal governmentality. The book explores how contemporary crises can trigger…

Our staff and students serve on task forces that aim to translate key Una Europa themes into concrete actions.

RAWCLIC’s main goal is to develop knowledge on the future raw materials (RMs) demand, supply and associated environmental impacts induced by the energy and digital transitions in the EU, and to support fact-based industry- and policy- decision-making enabling these transitions.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

The development of literary celebrity by focusing on five famous Dutch authors from the nineteenth century

Natashe Lemos Dekker addresses the experiences of family members of people with dementia as they expressed their sense of gradually losing the person with dementia in the article 'Anticipatory Grief in Dementia: An Ethnographic Study of Loss and Connection' published in Culture, Medicine, and Psychi…

These are our lecturers (in alphabetical order) for the 2025 Summer School in Languages and Linguistics.

Metal production is not only energy-intensive and a major source of greenhouse gas (GHG) emissions, but is also associated with other impacts affecting human health and ecosystems.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

Supply risks are not new. But the aggravation of power conflicts on the international stage coupled with global shifts towards energy transition and digitalization has triggered the next supply risk research era.

Migration and crime are in the spotlight in society. Within the Institute for Criminal Law and Criminology, research in this area has strongly developed in recent years. The concept of Crimmigration is central to this.

This thesis comprises the development of reproducible synthesis procedures for two-dimensional materials (composed of boron, nitrogen and carbon) on different metallic surfaces.
