The energy transition is a complex transformation process that is not only about technology -moving towards renewable energy sources-, but even more so about societal and institutional change. The energy transition requires and provides opportunities for actors to take on new roles.

Leiden Bio Science Park (LBSP) is the largest knowledge centre in the Netherlands in the field of life sciences & health and is also highly regarded internationally. The clustering of high-quality education, research, care and business attract students, scientists and entrepreneurs from all over the…

This research investigates the impact of socioeconomic developments on the physical condition of medieval populations in Holland and Zeeland between AD 1000 and 1600 through the analysis of human skeletal remains from three archaeological sites.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

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.…

“Transitional justice” is a field of practice, policy and study that focuses on the ways that societies respond to legacies of large-scale atrocities though tribunals, truth commissions, reparations, and other mechanisms.

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

How do academics develop into novel researcher roles alongside current teacher roles in the context of new universities in transition?

What is the state of access to justice in real property grievances in today’s Libya, and how should it be improved?

The overall aim of the project is to investigate interests and their development over time in a daily life context, with particular attention for the transition from late secondary to post secondary education, and from late post secondary education to early career.

These three repors are part of a research project that assesses how military interventions can best prepare the ground for an effective long-term counter-terrorism policy. Three different cases have been studied, and they have each provided the input for the policy relevant recommendations that are…

In December 2014, Leiden University’s Institute of Security and Global Affairs with the Australian National University’s Asia-Pacific College of Diplomacy and the International Centre for Counter-Terrorism, commenced a research project to assess how (temporary) military interventions can best prepare…

On Monday 9 May Mercury will pass between the Earth and the Sun. This rare event can be followed in the Leiden Observatory. The Observatory's new solar telescope produces a very clear image and offers a unique opportunity to observe Mercury at the highest magnification possible in the Netherlands.

The European Union increasingly needs to respond to unforeseen events and developments. This is putting it to the test. What are the effects? Professor of Foundations and Practice of the European Union Luuk van Middelaar addressed this in his inaugural lecture on 23 September.

Science in Transition joins an international chorus that points out flaws in the science system and aim for change in the governance of science.

In the coming decades, more than 2 million social housing units in the Netherlands will receive an upgrade in insulation and heating, in order to increase energy efficiency. To study the environmental, financial and social impact of this energy transition, a team of scientists from three universities…

Despite the rapid progress in solar and wind energy, a completely clean energy supply remains a huge challenge. Heavy industry, aviation, shipping and road transport are not yet able to do without carbon-based fuels. To reach the climate goals, in these industries energy consumption should be CO2 neutral. In…

To generate renewable energy takes more space than one might think. New research by environmental scientist Paul Behrens and master's student John van Zalk shows how much space is needed for nine specific types of energy. Biomass, hydro and wind, while vital, take up the most space. Natural gas and…

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

Following ASEAN Customs Transit System pilots in Cambodia, Lao, Malaysia, Singapore, Thailand and Vietnam, the ASEAN Customs Transit System (ACTS) system has now been formally launched for general use.
