Eco-innovations like more economical cars do not generate the environmental benefits predicted by the manufacturers. This is the result of the so-called rebound effect, concludes Leiden industrial ecologist David Font Vivanco on the basis of new algorithms. PhD defence 3 March.

On 5 September 2019, Jennifer Doekhie defended her thesis 'Dimensions of desistance: A qualitative longitudinal analysis of different dimensions of the desistance process among long-term prisoners in the Netherlands'. The doctoral research was supervised by Prof. P. Nieuwbeerta.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Fungi germinating in the lungs of patients. Doesn’t sound too nice, does it? Luckily, humans can deal with this normally, and we are able to clear the infection before anything comes to harm. However, in people with health issues, Aspergillosis can cause a lot of damage, especially if the fungus becomes…

Successful innovation requires more than technological progress alone. Every new concept must first be firmly anchored into an existing context. At least this is the hypothesis of Dutch classicists, working together in the National Research School in Classical Studies OIKOS. They intend to test this…

The Kenyan second-hand clothing market is depended upon locally by citizens for its low cost, high quality and diversity. To prevent the spread of the coronavirus, Kenya halted imports of second-hand clothes in late March. Ever since, local manufacturers and designers are looking for solutions and opportunities…

Leiden University is working on sustainability and should give its efforts more publicity. This is the conclusion of Industrial Ecology master’s students who investigated the extent to which Leiden University is green and sustainable.

Multiple identities of elites and ‘commoners’ viewed through the lens of crafting from the Chalcolithic to the Iron Ages in Europe and the Mediterranean

Hari Nugroho explores the role of local dynamics in shaping Indonesian labour movements. By focusing on the micro-level, this research reveals how labour organisation strategies are influenced by individual actors' personal histories, their interactions, and the way in which they respond the local economic…

The availability of natural resources, the energy transition, the importance of circularity and our dependence on China. This and more is what Professor of Industrial Ecology René Kleijn's inaugural lecture is about.

It’s not a regular occurrence at Leiden University: two professors giving their inaugural lecture on the same day. Berna Güroğlu and Ellen de Bruijn specialise in related disciplines: they both research the influence of social context on processes in the brain – Güroğlu in adolescents and De Bruijn…

Over 2,700 cars on the Fremantle Highway that caught fire on 26 July have been so badly damaged that they cannot be sold. Can we recycle these cars?

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…

How are you doing in these strange and unprecedented times? This is the question we are asking our colleagues in this series of articles. This time we asked Erick van Zuylen, the University beadle. 'This year, I haven't been leading the PhD committee into and out of the chamber, wielding my beadle's…

The Faculty of Archaeology's own home-grown journal Inter-Section has released a new volume. Inter-Section offers students and PhD candidates the unique chance to publish in a peer-reviewed journal. The new volume focuses on the materials that shape our world.

Practical advice, a panel discussion, and an informal networking reception: students and alumni from the MA International Relations can look back on yet another successful event last April. The diverse backgrounds and careers of the alumni vividly illustrated the range of opportunities awaiting students…

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

This thesis applies data mining in commercial settings in the telecommunications industry.

Leiden University has developed a radically different method for large scale production of diverse nanoparticles and their alloys.

This thesis investigates how quantum, quantum-inspired, and hybrid quantum-classical computation can enhance key points of the automated machine learning (AutoML) pipeline under the constraints of noisy intermediate-scale quantum (NISQ) devices.

This thesis investigates opinion dynamics on random graphs through the lens of the voter model, a classical interacting particle system used to describe how consensus emerges in networks.

The Belgian elections are over. Now it is up to the formateur to form a cabinet, but that is difficult. Fauke Deceuninck, program leader of Politics and Governance at the Center for Professional Learning, explains to Speechmakers why that is.

'Psychologists think I’m a linguist but linguists think I’m a psychologist,' says cognitive neuroscientist Xiaochen Zheng. With the Veni grant she will be able to bring these two fields of research closer together. Read her answers to five questions.
