Helping people, groups and policymakers navigate the social transitions of our time.

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.

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.

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 expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

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.…

The transition to electric vehicles (EVs) reduces vehicle emissions to combat climate change. EVs raise concerns regarding the production of lithium-ion batteries and related emissions; while batteries can also provide energy storage services for the electricity system.

This thesis describes the Multi-site All-Sky CAmeRA (MASCARA), which consists of two small robotic telescope designed to detect exoplanets around the brightest stars in the sky.

“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.

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…

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

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.

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.

The global transition toward low-carbon energy systems and the rapid expansion of digital technologies, including artificial intelligence, are reshaping how modern societies produce, move, and process energy and information.

On Monday 21 November a lecture was given at Leiden Law School of Leiden University by Belgian Minister of Justice Koen Geens and Dutch Minister of Justice and Security Ard van der Steur in which they talked about international judicial cooperation. The lecture focussed on cooperation between the Netherlands…

The AT-Hook Nuclear Localized 15 (AHL15) gene belongs to a plant-specific gene family of DNA-binding proteins. Overexpression of AHL15 in Arabidopsis thaliana delays developmental phase transitions whereas its loss of function causes a slight acceleration.

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

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…

How did people across Central and Eastern Europe imagine the future during the transitions of the 1980s and 1990s? The umbrella term ‘post-communism’ does not provide an answer to this question. This project explores how writers and cultural theorists saw the potential future of their societies during…

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

In this article, Annemiek de Looze and Eefje Cuppen, investigated empericallly if and how social conflict leads to institutional change.
