The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

A tidal basin is an inland sea which is almost entirely enclosed by land and connected to the open sea by a tidal inlet. Through the tidal inlets interaction takes place between the tidal basin and the open sea.

This study looks at population response to government containment strategies during initial stages of the COVID-19 pandemic in four high-trust Northern European countries–Denmark, Germany, the Netherlands, and Sweden–with special emphasis on expressions of governmental trust.

This perspective addresses four challenges facing theorists whose aim is to make quantitatively accurate predictions for reactions of molecules on metal surfaces, and suggests ways of meeting these challenges, focusing on dissociative chemisorption reactions of H2, N2, and CH4.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

On the 31 March 2022 Mr. Taufiq Hanafi successfully defended a doctoral thesis and graduated.

A semi-empirical version of the specific reaction parameter approach to density functional theory (SRP-DFT) has been remarkably successful at predicting dissociative chemisorption probability vs. incidence energy curves for reactions on metal surfaces. New quantum Monte Carlo (QMC) calculations on the…

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

Apps that can precisely identify shards, coins or heel bones: archaeology has embraced artificial intelligence. Alex Brandsen is working on a search engine that scans vast quantities of text from an archaeological viewpoint.

In 2022, local residents, businesses, students and other stakeholders were involved in discussions about the alternative plan for the Humanities Campus. Their feedback was given careful consideration in formulating the new urban development plan, which was made available for inspection at the municipality…

Neanderthals were able to outwit straight-tusked elephants, the largest land mammals of the past few million years. Leiden professor Wil Roebroeks has published an article about this together with his German colleague Sabine Gaudzinski-Windheuser in the Science Advances journal.

Does the presence of Ring-necked parakeets negatively influence feeding and feeding behaviour of native bird species on artificial bird feeders and if so, what are possible solutions?

How the systematic destruction of valuables created value in Bronze Age Europe, c. 2300-500 BC

This is the 2017 paperback release of William Michael Schmidli's The Fate of Freedom Elsewhere, which won the 2013 Foreign Affairs Magazine Best Book of the Year.

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

Adoptees in the Netherlands generally do not use more medication than their non-adopted peers.

When psychologists repeated a hundred studies in 2015, their results differed in two-thirds of the studies. ‘Research into research is not a luxury but a necessity,’ says Professor of Methodology and Statistics of Psychological Research Mark de Rooij. ‘My aim is to improve psychological research, to think…

The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. This territorial sweep is both a source of fascination…

Early cave paintings of hunting scenes may give the impression our Stone Age ancestors lived mainly on chunks of meat, but plants were just as key to their survival. Plants rich in starch helped early humans to thrive even at the height of the last Ice Age, Leiden archaeologist Amanda Henry tells Horizon…

A Leiden and Mainz (Germany) based team studies the activities of early humans in a 125,000 years old Last Interglacial ecosystem, formerly exposed in a large open cast brown coal pit near Halle (Germany). The Last Interglacial is an important warm-temperate period, showing the full flora and fauna…

The ‘Amorphophallus titanum’ at the Hortus botanicus Leiden is blooming. This Titan Arum, also known as the ‘giant penis plant’, last flowered in 2009.

Here you will find an overview of the Spaces for Active Teaching and Learning already implemented at Leiden University and LUMC. These rooms vary in size, location, material affordances, and technological affordances, and thus vary in the forms of pedagogy they best support. You can use this site as…

Neural networks have a wide range of applications. In Leiden, psychologists use them to build robot brains, whereas archaeologists use them to hunt for prehistoric graves.

The Persian Empire (539-330 BCE) was the first world empire in history. At its height, it united a territory stretching from present-day India to Libya - and it would take 2,000 years before significantly larger empires emerged in early modern Eurasia. Its size and power was revered by some, feared…

The Moving Days will take place on 16-17 August 2023. In order to prepare yourself for your Moving Day, we want to share with you some more info, and what to expect before this date. DUWO - our student housing partner that deals with LUC's housing will be in touch with you in the summer to start…

Every day we make use of devices, services and apps which contain algorithms that could be discriminating. These range from Facebook to self-driving cars, from the Tax Authorities to a rotating door.

Universe Awareness (UNAWE) started a crowdfunding campaign together with Design & Data GmbH, with a central role for the plush 'astronaut' Rosetta. This stuffed toy is used for interactive classes, in order to teach pupils across the world about astronomy and space sciences.

Can trees adapt to (climate) change? Which trees are more or less capable of doing so, and why? A group of researchers from all over the world set to work on these questions. Professor of Environmental Biology Peter van Bodegom helped to classify the functional traits of tree species. These are for…

The Greater Angkor Region in contemporary Cambodia was dramatically more urbanized in the 13th century than previously thought, and home to 700.000 to 900.000 people. These discoveries were made by a research team led by Sarah Klassen. Their findings are published in Science Advances.

On December 16th 23 students of the Institute of Environmental Sciences of Leiden University took part of the first total species inventory to assess the effectiveness of an underwater landscape that was build in March 2003 to restore the biodiversity in an area where the environment was destroyed by…

Physicist Scott Waitukaitis receives an NWO Veni grant to research the Leidenfrost effect for squishy materials. This effect is well-known for dancing water droplets in a frying pan.

Ludo Waltman, professor of Quantitative Science Studies at Centre for Science and Technology Studies (CWTS), has been awarded the Derek de Solla Price Medal.

Many students are finishing their master thesis on sustainability this summer. In this blog, we reflect on their topics, approaches, and goals by highlighting theses from Governance of Sustainability, European Law, Global Archaeology, Computer Science: Artificial Intelligence, Industrial Ecology, and…

In prehistoric times there was a huge wave of migration, from the steppes in Russia and Ukraine to West Europe. The newcomers’ genes began to dominate. Archaeology research in Leiden into burial mounds in the Veluwe and Utrechtse Heuvelrug areas of the Netherlands yielded this spectacular conclusion.…
