Circular economy… is it another a buzz word or a concept worth learning more about?

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Reuse everything and stop producing waste. By 2050, the Netherlands should have a circular economy. However, the new Integral Circular Economy Report by the Netherlands Environmental Assessment Agency (PBL) shows that there is still a long way to go. For the report, the Institute of Environmental Sciences…

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

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.

How to ensure the environmental and economic benefits of circularity transition at macro-scale?

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…

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.

How do we approach education that facilitates creative confidence for students that leads to innovative solutions to society’s present day and future sustainability challenges? This education research project tackles a sustainability dilemma faced by households in everyday life viz.

Research and design are becoming more and more important in international science education. In The Netherlands, two recently introduced subjects focus on research and design activities in the classroom: O&O (research and design) and NLT (nature, life and technology). This research aims to look at what…

Procedural administrative law in a constitutional comparative law perspective

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?

In 2021, the National Cyber Security Centre (NCSC) asked Leiden University to conduct a rapid review of best practices and possibilities for follow-up research on the integration of behavioral sciences in security by design methodologies and projects. This academic field is called security by behavioral…

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.…

This research intends to study the why, what, how and the possible outcome of internationalisation in higher education institutions of fine art and design.

In the first part of this thesis we study the geometry of folding patterns.

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…

The studies reported in this thesis were situated in the context of an innovation of Dutch secondary school biology curricula. As in any innovation, the practical knowledge of teachers determine the outcomes through the decisions they make while planning and teaching their lessons. The aim of the studies…

Consumer societies are a global presence, and marketing practices have spread to all corners of the world. However, the loud and glaring performances of the big advertising companies and the hegemony of shopping malls makes us forget that there are many different markets, and many merchants who have…

Even a small quantum computer should be able to simulate exactly the properties and behaviour of new molecules. This would take chemistry to an entirely new level. Better solar panels, more powerful batteries, saving lots of energy in the chemical industry: the applications have the potential to transform…

Research and design are two activities that are becoming increasingly important in the Dutch subjects O&O (‘research and design’) and NLT ('nature, life and technology’). The dissertation of Tessa Vossen (ICLON and Faculty of Science) indicates that teachers and students understand the importance of…

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

Beginning teachers often experience difficulties making activating lessons. This study investigates how and if the practical teaching model can offer them a hand in learning to design lessons.

The Automated Design and Analysis of Algorithms (ADA) research group pursues the development of Artificial Intelligence techniques that complement, rather than replace, human intelligence.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

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.

This doctoral research project in design seeks to shed a light on legibility in the context of visually impaired beginning readers.

How to contribute to a quantum leap of eco-industrial symbiosis in China?

Bruno Munari (1907–1998) was a prolific and influential artist, designer, and writer. Alessandro Colizzi’s study is the first extensive, detailed record of Munari’s graphic design production, and as such provides a substantial base for a full understanding of his oeuvre.

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…
