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.

Submissions are sought for a special issue with Frontiers in Political Science that explores the conceptual and practical aspects of a ‘just’ energy transition both within and beyond Europe. In particular, contributions to the theoretical and interdisciplinary foundations of just transitions, as well…

A wide range of metals need to be mined for solar panels, wind turbines and batteries. But the overall mining activity is set to decrease as clean energy replaces fossil fuels such as oil, coal and gas.

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

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…

The vegetative growth period for leafy vegetables like lettuce is essential for yield and quality.

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.

RAWCLIC’s main goal is to develop knowledge on the future raw materials (RMs) demand, supply and associated environmental impacts induced by the energy and digital transitions in the EU, and to support fact-based industry- and policy- decision-making enabling these transitions.

A consortium including economists, psychologists and public administration scholars from Leiden University will study public acceptance of the hydrogen transition in the Netherlands. They will look at the labour market impact, public perceptions of hydrogen and businesses’ willingness to invest.

À La Découverte de la Hollande dans les années 1760-1770 : Pierre Famin, Emmanuel de Croÿ-Solre, François-César Le Tellier, Jean-Marie Roland de la Platière, Gabriel-François Coyer.

This interdisciplinary study focuses on (trans)national ethnic and popular networks, combining historical-ethnographic and computational methods to understand the ‘workings’ of networked conflict interfering in the increasingly violent conflict in the Sahel (Africa) and beyond. The project focuses on…

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.

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 gas prices now exceed 300 euros per megawatt hour – a record. The transition from fossil (natural gas, coal, oil) to renewable energy is needed and soon. But how do you get a society (and its citizens) to switch to sustainable energy?

CML-researcher Rene Kleijn has spoken about metals scarcity in relation to the energy transition in a new Dutch popular scientific TV show called

Almost a century passed since the much-celebrated judgement in the case concerning the Factory of Chorzów was delivered. This 1928 judgement of the Permanent Court of International Justice affirmed the essential principle of ‘reparation’ in international law, claiming that ‘restitution’ is the preferred…

Due to technological change, jobs and professions are constantly changing. For instance, it has long been known that some jobs are becoming redundant due to automation. Digitalisation and the rise of artificial intelligence are more recent developments that affect the labour market.

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.

How can innovation help or hinder public procurement processes?

De menselijke geschiedenis strekt zich ver uit vóór de tijd waarin de mensen opschreven wat er zoal gebeurde.

Dit rapport maakt deel uit van het project Receptenboek burgerparticipatie in opdracht van de Rijksdienst voor het Cultureel Erfgoed (RCE) en met steun van het Fonds voor Cultuurparticipatie.

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?

Africa is seen as a potential leader in green hydrogen production for domestic consumption, export and greening industry. One key barrier to realising this potential is the mismatch of skills between those required by industry and the capability of local workforces.

In the early universe, the dynamics of the Higgs field can give rise to many interesting phenomena.

What does digitalisation mean for the labour market, the business sector and society in general? Reijer Passchier, Assistant Professor Leiden Law School and Professor of Digitalisation and the Democratic Constitutional State at the Open University, spoke at a meeting of the Social and Economic Council…

Decarbonizing the building stock is critical for realizing the climate-neutral target for the Netherlands.

National and international actors have attempted to provide accountability for the events at Srebrenica in July 1995. This research project aims to draw lessons learned from those multiple efforts in assessing whether securing a measure of ‘justice’ for the victims has been successful and how national…

This thesis advance our understanding and the application of molecular catalysts relevant to the reduction of oxygen as well as reduction of nitrite.

Density functional theory (DFT) with so-called semi-local exchange has been remarkable accurate for some dissociative chemisorption reactions on metals, but it has notoriously failed for others. A team of researchers from the University of California at Irvine and the Leiden Institute of Chemistry have…
