The main focus of this thesis is the behaviour of two-dimensional materials, namely (anti)-ferromagnetic materials in the first two chapters, which show topological phases, and energetic square ice in the third and fourth chapter.

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.

Robert Pee, William Michael Schmidli (Eds.) This book posits that democracy promotion played a key role in the Reagan administration’s Cold War foreign policy.

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.

This project investigates the causes of the major archaeological change in the period of 40.000-20.000 BC in South Africa.

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…

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.

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

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.

“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.

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…

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

What are key regulators of plant ageing that can reverse ageing in plants (rejuvenation), and how can we use this knowledge to improve crop plants?

A 35-year-old uranium crystal will not disclose its secret: what causes a dramatic phase transition at 17.5 Kelvin? Thanks to a new artificial intelligence approach, half of the possible explanations are excluded, but the definitive answer remains to be found. 'It is very frustrating', says physicist…

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…

The current production of a number of critical metals is insufficient for the large-scale transition to electric vehicles. This is the conclusion of a report by environmental scientist Benjamin Sprecher and organisations Copper8 and Metabolic. As a solution, they advocate more electric car-sharing,…

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

Dr. Moritz Jesse, associate professor of European Law at the Europa Institute Leiden, was sharing his thoughts on the transition from asylum seeker to refugee from a perspective of immigrant integration in Prague.

The present market regulations make it extremely risky to invest in green energy, and this is impeding the fight against climate change. This is what Oscar Kraan writes in his dissertation. PhD defence on 25 April.

Jens Iverson, Assistant Professor of International Law and a Researcher in the Jus Post Bellum Project, defended his Ph.D. dissertation on 21 September 2017.

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.

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…

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…

Have you had your eye on one of our Summer Schools? Or perhaps a Summer School elsewhere to complement your Law Master, but you have not been able to decide whether it has enough added value? One of our international alumni, Mariasole Forlani, tells us enthusiastically about her experience of the international…
