How can society let go of its obsession with economic growth and focus on goals as wellbeing, inclusion and sustainability? This is one of the core questions which a new 3 million euro European project will tackle the upcoming four years. Leiden University researcher Rutger Hoekstra is project coordinator…

Healthy and active Leideners and a smoke-free generation. These are the main ambitions of the Leiden Health and Wellbeing Agreement that was signed online by 40 partners on 19 April. Leiden University will also be drawing on its broad expertise to help realise the ambitions.

‘Shouldn’t you get out of bed for once?’ Critical or controlling behaviour from parents, however well intentioned, can worsen the symptoms of young people with depression. That is the conclusion of PhD research by psychologist Wilma Wentholt. But warmth and emotional support can, in fact, have a protective…

To meet the rising demand for minerals driven by the global shift to clean energy technologies, ensuring responsible and resilient supply chains is critical. Minerals like cobalt, lithium, and nickel for batteries, neodymium and zinc for wind turbines, and indium for solar panels are essential.

Nina Baranowska and Gianclaudio Malgieri have published a new blog post on Verfassungsblog: 'Towards a Legal Concept of Digital Well-being: Insights from the EU Commission’s Preliminary Findings on TikTok’s Addictive Design'.

Global health governance is at a crossroads. As the world reckons with the existential threat of planetary crises (climate change, loss of biodiversity and pollution), international policy frameworks struggle to keep pace with a rapidly changing landscape in global health and public health.

NWO has awarded a €392k Projectruimte grant to physicists Koenraad Schalm and Jan Zaanen to study ‘strange metals’. These materials are alleged to follow the bizarre laws of quantum mechanics even at everyday length scales.

Home workers experience less time pressure and feel better as a result. This appears from PhD research conducted by Maral Darouei, who defends her dissertation from home on 9 June.

Childhood sexual abuse is a common problem, with approximately one in five girls and one in 13 boys worldwide experiencing some form of sexual abuse before the age of 18. Despite its high prevalence, many individuals remain silent about these experiences, often delaying disclosure for years, with one…

From 23 to 26 November, FGGA will once again be organising the online Well-Being Days. Four days of great articles, handy tips and (online) activities. Especially for students, but also very interesting for employees. For example, read about the benefits of walking and get the best walking routes through…

Research at the MCBIM group is comprised of the following research themes:

Playing a game, picking a cutting for your room or just having a cup of coffee: it is all possible in the new Humanities Living Room in the Matthias de Vrieshof. From Wednesday 17 May, staff and students will be able to meet informally and socialise here.

How can social scientists contribute to a healthier society? That question was central to the Healthy Society Event on 9 June 2022, which successfully marked the start of a more conscious and intensive collaboration between the five Institutes of the Faculty of Social and Behavioural Sciences on education…

The COVID-19 pandemic and associated measures during the first lockdown in the Netherlands in March 2020 caused major changes in daily life. Parents worked from home and children followed school online. Therefore, the families were forced to spend more time together. This is particularly difficult for…

Tin electrodeposition applications have rapidly evolved in the past 25 years.

Chemical reactions go hand-in-hand with an energy exchange with the environment in which they take place. Surfaces offer a variety of energy dissipation channels, constituted by the nuclear and electronic degrees of freedom of the atoms at the interface. Aiming at an improved future harvesting of energy,…

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.

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…

Research projects for students of the University of Leiden and other Dutch Universities are often available at the MacBio group. The research lines are also described in the Research section. For details of specific projects contact the supervisor (Ubbink, Dame, Boyle, Jeuken or Wentink).

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…
