This thesis studies theoretical surface chemistry within the field of heterogeneous catalysis.

A source of inspiration for readers who are curious to understand how people move and convince each other

The main goal of the THEOR CHEM group, headed by Prof. Geert-Jan Kroes, is to characterize, and to accurately predict the outcome of chemical reactions at gas-solid and liquid-solid interfaces. Here the solid surface is typically a metal or an ice surface. These goals are important to many areas in…

From 17 to 19 September, the University of Granada organized the 27th International Conference of the Spanish Society for Medieval English Language and Literature (SELIM).

From 6 to 9 May the Law's pluralities conference was held at the Justus-Liebig-University in Giessen. Highly interdisciplinary in the areas of literature, art and law.

Whether implicitly or explicitly, we all have ideas about how the law is supposed to function, whose interests it should represent, and what role it should play in society. This project explores the ways in which these questions are addressed in the works of the Roman historian Publius Cornelius Tacitus…

This project investigates the full ecosystem of Middle Dutch prayerbooks in order to answer questions about their role in – and impact on – religion, culture, and society in the late medieval Low Countries.

In Renaissance Florence, humanists wrote Latin poems fashioning their city as the new Rome, and members of the Medici family as Roman rulers. How can we explain this practice?

On 12 January 2022, Mirjam Franke defended the thesis 'Over de grens van de onrechtmatige daad'. The doctoral research was supervised by Prof. A.G. Castermans and Prof. J.H. Crijns.

What role do parent-child interactions play in the development, maintenance and treatment of depression in young people?

Under Dutch law, like German or English law, the violation of a statutory provision does not establish civil liability for damage caused to another person. Such liability requires that the statutory provision concerned aims to protect against the damage or, put differently, that the harmed interest…

Despite their ecological, cultural, and economic importance, lion (Panthera leo) populations in Kenya are declining rapidly due to retaliatory killings following livestock depredation, depletion of wild prey, habitat loss driven by human activities, climate change, and disease.

How does environmental heterogeneity shape biodiversity across spatial and temporal scales?

As Scaliger professor, Erik Kwakkel is responsible for the academic context of the complete Special Collections of the Leiden University Library. His inaugural lecture on 15 May will focus mainly on the section closest to his heart: Medieval books.

Joost van den Vondel is considered to be the greatest Dutch poet and playwright of his time, but he certainly wasn’t the most popular. The 17th- and 18th-century public preferred to watch ‘Spanish theatre’. University lecturer Olga van Marion has written a book about this, together with Frans Blom (University…

Every month a member of the Institute for History tells about a book that inspired him or her. Afterwards, the pen is passed on to another colleague. This month dr. Robert Stein tells about the book 'La Vérité sur l'affaire Harry Quebert' by Swiss writer Joel Dicker. It is not so much the whodunit that…

A delegation of the Institute of Environmental Sciences (CML) of the Faculty of Science of Leiden University, led by the Dean of the Faculty of Science: Prof.dr. Geert de Snoo, visited the Kenyan ambassador Mr. Lawrence Lenayapa and his staff on Monday 29 of October in The Hague.

This project investigates how the first generation of Dutch printed books (the incunabula, 1473-1501) affected late medieval spirituality, religious practice and visual culture in the Low Countries.

On July 8 and 9, 2022, Leiden University hosted the second conference of the research group on Institutions for Conflict Resolution, in collaboration with Radboud University Nijmegen and Utrecht University.

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…

The Netherlands is not particularly rich in ‘wild nature’. Comparatively, what we have is a lot of intensively used agricultural land. This means that from nature’s perspective there much to be gained by combining the ‘nature’ and ‘agriculture’ functions. Not an easy task in such a densely populated…

How can reciprocal learning of mentor and mentee about PCK (Pedagogical Content Knowledge) during the secondary school internship be established?

The research profile area Interaction between Legal Systems has a multidisciplinary approach and aims to inspire innovative research. Out of all the proposals put forward, three winning projects have been selected for the forthcoming research period 2016-2020.

LACDR is committed to incorporating sustainability into our education and research. By developing environmentally responsible innovations in drug research, promoting the awareness of the importance of sustainability with LACDR staff and students, and implementing sustainable daily practices within our…

Na de 7 oktober demonstraties schoffeerde Wilders burgemeester Halsema, door op X te roepen dat zij het land moet verlaten. Volgens experts overtreedt Wilders hiermee de gemaakte afspraken met de coalitiepartijen. Wim Voermans, hoogleraar Staatsrecht, hierover aan het woord in het Parool.

In honour of 10 years of cooperation between Kenya Wildlife Service and Leiden University, a Leiden delegation visited Nairobi National Park. To cement the cooperation, a lion in the park was collared and named Karel, which in Dutch literally means ‘free man.’ It will be monitored through satellite…

At the invitation of the Centre for Early Christianity and Its Reception (CECIR), Peter Liebregts, Full Professor of Modern Literatures in English (LUCAS), visited the University of Kent in Canterbury from March 17 to 20, to give a lecture and a masterclass.

Emma de Vries, PhD researcher at LUCAS, has been awarded with a Fulbright Grant and Prins Bernhard Cultuurfonds Scholarship. From September 2015 onwards, Emma will spend a full academic year in the Unites states, to work at UCLA and Harvard on her PhD research on Neo-Epistolarity.
