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…

The Faculty of Social and Behavioural Sciences provides its ca. 5000 students with a thorough education in the social and behavioural sciences. The student population is very diverse and international in nature.

On 20 September 2019, the opening drinks for the Open Science Community Leiden will be held at the Faculty of Social and Behavioural Sciences. Open science is the approach to science aimed at making scientific research accessible, reproducible, and freely available to people within and outside the academic…

I will give a general introduction to the field of molecular electronics, its history, methods and challenges. I will also introduce the subject of my investigation and provide a brief outlook to the remainder of our thesis.

The demolition of the high-rise building is ready. The remaining debris are removed and the area is cleared. For the demolition, the University applied the BREEAM evaluation method at the level of ‘Excellent’, which means that the demolition operations were carbon neutral and did not cause any form…

There are around 300,000 people in the Netherlands who donate blood on a regular basis. Women can give blood up to three times a year and men up to five times, resulting in approximately one million blood donations each year. Patients that receive this donated blood are already in a vulnerable condition,…

More European countries are introducing border controls, clashing with the ideal of free movement within Europe. Daniel Schade, Assistant Professor of EU Studies at Leiden University, analyses this development in The Washington Post.

Most degree programmes at the Faculty of Social and Behavioural Sciences are based in the Pieter de la Court building on the Wassenaarseweg in Leiden. Besides this location, some degree programmes are based in The Hague, at Campus The Hague’s Wijnhaven building.

In this thesis three different topics in number theory are studied.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

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.

This thesis aimed to investigate the impact of exposure dynamics, relative contributions of ENPs(particle) and ENPs(ion), and dosing regimens on the toxicity of ENPs varying in different physico-chemical properties, on the composition and functioning of soil microbial communities.

Workshop

A new university-wide survey is now open to all involved in conducting, teaching, advising on, or supporting research related activities at Leiden University, aiming to better understand the current state of Open Science awareness and practice. Initiated by Archaeology’s then PhD candidate, now guest…

Professor Pieter ter Keurs has spent his entire career studying collecting. Now, he is retiring. ‘I hope the focus on collections will carry on.’

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

The Faculty of Social and Behavioural Sciences brings together high-quality research and outstanding teaching.

In comparing a selection of 18th-century histories to a representative sample of 19th-century histories of science, this project inquires: Which early modern vices persisted into the 19th century and to what extent were those vices embodied in anecdotes, conveyed through commonplaces, or symbolically…

Study information

Fifteen knowledge institutions and the Ministry of Education, Culture and Science have signed the covenant for Open Science NL. Leiden University has also joined the covenant, via the Universities of the Netherlands. This marks the start of the Dutch Research Council’s and brings the transition to open…

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.
