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…

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.

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.

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.

If there is anything you want to know about the English Language and Culture bachelor’s programme, or if, perhaps, there’s another way in which you think we might be able to help you, don’t hesitate to get in touch with us.

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

Henk Hoekstra and Alessandra Silvestri work on the astronomy and theoretical physics in the Euclid mission. These Dutch researchers are part of the mission.

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.

Can a robot perform a religious ritual just like a monk? And what exactly is a religious ritual? Robots and religion seem to be two different subjects, but according to university lecturer Elpine de Boer, both can make us think about what it means to be human and what we consider to be of value. Together…

A public symposium was held at Leiden University on 20 February on a hot topic: renewable energy. This is the second time in a year that the University has organised such a symposium. The previous one, about Artificial Intelligence, was a big success.

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.

Getting to know all his colleagues as fast as possible, and learning about the faculty’s strengths: these will be Jasper Knoester’s first challenges. Jasper became the new Dean of the Faculty of Science on 1 January, and he is optimistic about the corona restrictions. ‘Obviously, this isn’t the start…

Can students help make our cities more sustainable and resilient? The Resilient Cities Hub thinks so: during its knowledge café on 16 January, passionate students talked to municipal officials and pitched their master’s research. ‘In this way, the students learn to step out of the academic world and…

Through metabolism, biochemical processes give rise to the complexity of life. Acquired and inborn errors in metabolism underlie many diseases occurring in man. The challenge for present day medical biochemistry is to find, and integrate, pieces of information at molecular, cell and organismal level…

The focus of the dissertation

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…

On the 6th of December, Buurtlab 070 and the Leiden University Green Office (LUGO) hosted an event at the Spinozahof in the Stationsbuurt, bringing students and local residents together to explore energy (in)justice through the serious game Sunjust.

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.

The glycosylation reaction is a pivotal reaction in creating new and complex oligosaccharides.

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

German-American Mia Müller (26) has been working at the European Parliament for three years now as Press Officer at The Greens/EFA Group. She is a bit nervous about her 'first' elections.

It’s become somewhat of a tradition at Leiden University: the strategic conference at the end of June each year. About a hundred staff including the faculty boards, academic directors, directors of the expertise centres and Administration and Central Services, the representative councils and student…

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

As early as 2030, batteries in electric vehicles could fully meet the need for short-term electricity storage around the world. By connecting them to the power grid they can provide their stored energy, improving energy security and enabling renewable technologies in cleaning the grid.

A more efficient solar panel sounds great. But what if these new panels consume more toxic materials, or their production consumes a lot of energy? Leiden environmental scientists, together with colleagues from the Fraunhofer ISE, address this multifaceted question in a new publication in the prestigious…

This thesis contributes to studying primordial cosmology theories and their detectability in future observations.

This thesis is dedicated to the exploration of the primordial dark ages: unknown physics during the earliest stages of the Universe’s expansion that have not yet been directly probed by observations. Cosmic inflation is a burst of exponential expansion of space after the “Big Bang”.

The vulnerability of the European electricity sector to changes in water resources is set to worsen by 2030 as a consequence of climate change. This conclusion is reached by researchers at Leiden University in an article published in Nature Energy this month.

The roof of the lecture halls at the Faculty of Science was fitted with solar panels in June, making it the biggest solar-panel-covered roof in Leiden.

New results from the Kilo-Degree Survey (KiDS) show that the Universe is almost 10 percent more homogeneous than previously thought. The new KiDS map was created using the partly Dutch OmegaCAM on ESO's VLT Survey Telescope on Cerro Paranal in Northern Chile. An international team of astronomers from,…

Papyrology+, founded in 2014, is a collaboration of Leiden scholars studying (Abnormal) Hieratic, Demotic, Aramaic, Greek, Latin, Coptic, and Arabic papyri from a socio-historical, economic and linguistic perspective. Papyrology+ aims to explore new opportunities and directions in the study of ancient…

A discovery made in Leiden helps not only to make natural gas from CO2 but also to store renewable energy. Research by Professor Marc Koper and PhD student Jing Shen shows how this process can be implemented in a cost-effective and controllable way. Nature Communications, 2 september 2015.

It must be there. We just cannot see it: mysterious dark matter and dark energy in the universe. Henk Hoekstra is one of the many cosmologists who would love to know what exactly these substances consist of. He has received a European research grant of 1.3 euro million to find out.
