In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

Material circularity and energy efficiency are highly relevant and intertwined issues for the transition towards a carbon-neutral and circular built environment. In the Netherlands, the building sector has been rendered a priority towards a circular and low-carbon society.

Some examples of research questions include: What framework of circular strategies should local practitioners use? How should practitioners organize their monitoring of the circular economy activities in the region of interest? What are the main products that have the most circular potential in the…

In the globalised world of today, traditional definitions of national Self and national Other no longer hold. The unmistakable transformation of German and Dutch societies demands a thorough rethinking of national boundaries on several levels.

Proteases degrade matrix molecules in the atherosclerotic plaque, thereby reducing atherosclerotic plaque stability. Mast cells, that contain proteases such as tryptase and chymase, have been identified at the site of rupture in specimens of human coronary arteries and their number in the plaque was…

Consensus and harmony or balance and reciprocity?

What are the mechanisms involved in the reconciliation of value conflicts and which interventions are capable of resolving such disputes?

How can we, together international experts, define future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products in a global perspective using alternative testing strategies to minimize animal tests?

This thesis aims at thinking through the ethical position of animals in a way that differs radically from the manner in which this ethical position is thought within contemporary animal rights discourse.

It’s Circular Economy Week, from 1 to 6 February. But what is it that makes an economy circular? And just how circular is our university? René Kleijn, lecturer on the honours class Circular Economy: from challenge to opportunity, explains.

How can we speed up the transition from large cities to a circular metropolis? This is the question that Leiden students and former students Elsemieke, Fabian and Eveline are getting their teeth into. They and seventeen other young academics are taking part in the National ThinkTank and they have four…

Can SMILE, our multi-component intervention, which combines cognitive-behavioural therapy for insomnia, mindfulness, stress, and lifestyle components, improve sleep quality? Can it also improve mood and quality of life and prevent depression and anxiety in the long term?

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…

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…

As soon as young children are introduced to rules and start to learn to obey to those rules, it can be difficult for parents to remain sensitive when their children try to bend or break those rules. The short-term (preventive) VIPP-SD intervention aims at enhancing parental sensitivity in interaction…

What is the role of local authorities and communities in shaping how inter-Schengen borders are understood and dealt with?

Fewer CO2 emissions, less airborne viral transmission, and a more sustainable form of food production: seven consortia of researchers and societal partners will put a budget of 32 million euros towards developing technological innovations. Important Leiden research on circular electronics by Prof. Dr.…

Doctoral research on recent developments in museological practices by “critical” curators, interventionist artists, and personnel initiatives, focusing on ‘queering’ as an entrance point to broader intersectional issues; resulting in a report on the ‘Queer Baseline’ (to be launched in 2020), a popular…

A scenario building web-tool and knowledge package to enable multi-level decision making for the transition to the Circular Economy

On 22 January 2018, the Massive Open Online Course ’A Circular Economy of Metals: Towards a Sustainable Societal Metabolism’ kicks off. This course is developed and taught by associate professor Ester van der Voet.

A python3 package to create and analyze Circular Economy scenarios.

This project aims to identify which aspects of exploring a novel environment produce beneficial effects on memory. The effects of novelty will be investigated across the lifespan, including children, adolescents and older adults.

The renovation of Cluster Zuid (Van Eyckhof-Van Wijkplaats) is the third project in the development of the Humanities Campus. The circular dismantling of Cluster Zuid has started.

A new study on the province level material footprint of China underscores the need to improve resource efficiency in the country, which would be crucial for moving to a circular economy. The research carried out by researchers from Tsinghua University in Beijing, China and Leiden University was published…

Can a newly developed, app-based, personalized maintenance program enhance the effectiveness of the exposure-based one-session-treatment for children with a specific phobia?

PhD defence

The role of material production as a driver of environmental impacts is increasing, which calls for a better understanding of global material flows. This thesis explores the role of in-use stocks of products, buildings and infrastructure as a key driver of global material demand and discusses the implications…

We found that, next to the effectiveness of the intervention, it’s also very likely that the intervention is cost-effective compared to attention only.

A circular economy in which all resources are reused is a prerequisite for a sustainable world. As EU president, the Netherlands can give a firm impetus to this economic shift. This is the message of Leiden Professor of Industrial Ecology, Arnold Tukker, in his inaugural lecture on 26 February.

An international consortium headed by the Leiden-Delft-Erasmus Centre for Sustainability has been awarded a subsidy for research on the circular economy where all raw materials are recycled.

The province of Zuid-Holland faces a wide range of global sustainability issues caused by urbanisation, intensive horticulture and industry. The universities of Leiden, Delft and Rotterdam have the in-house expertise to define knowledge questions, set up research programmes and test results, says Prof.…
