How can we reuse the burnt cars from the Fremantle Highway?
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?

Return of customary law often a let-down for local people
Traditional leaders in many African countries have regained some of their former powers. Politicians and companies in some of these countries manage to gain access to valuable land via these leaders, at the cost of the local population. This is the message of Professor of Law, Administration and Development…

Sparks on the Reuvensplaats
Making fire is no simple matter. This became abundantly clear during the demonstration by German archaeologist Jürgen Weiner. Weiner was invited by Professor W. Roebroeks to share his practical knowledge about fire. The Human Origins group of the Faculty of Archaeology organised a guest lecture and…

Building materials drive carbon emissions, and they’re set to grow
A new study from Leiden researchers shows that the carbon emissions of building materials are set to grow if we do not act rapidly. Even with known interventions implemented in concert, these emissions are much larger than the remaining 1.5 degree budget for building materials at today’s share, the…

Will soap and sunlight solve the energy problem?
A consortium of international researchers comes with a unique solution to the energy problem. By mimicking photosynthesis, they aim to produce sustainable fuels out of sunlight, water, and CO2. Their secret? ‘Soap bubbles’, says Leiden chemist Sylvestre Bonnet, who is part of the consortium.

Playing with light and shadow
Depictions of Rembrandt, Michelangelo and many other artists are given a new dimension in an exhibition in the hall of the Oude UB at Leiden University. The exhibition - 'Multiple Images' - opens officially on 15 February. Artist Rudi Struik has given the slides of Leiden art historian Henri van de…

Recycling at microscale
Playing with tiny building blocks might sound like child’s play, but Vera Meester knows better. On June 7 she will defend her thesis on colloids: micro particles with which you can form larger structures. Meester developed a method to make unusable structures usable.

Using gold particles to make the invisible visible
Gold nanoparticles give us a better understanding of enzymes and other molecules. Biswajit Pradhan, PhD candidate at the Leiden Institute of Physics, uses gold nanorods to study individual molecules that would be challenging to detect otherwise. Resulting knowledge can be applied to many research fields,…

Designing better catalysts using simple chemical concepts
An international team of researchers, including Federico Calle-Vallejo of Leiden University’s Institute of Chemistry, have taken the atomic-scale design of catalysts to the next level. Their research contributes to the quest for a method to generate or store energy more efficiently. The report is published…

New scanning method turns objects inside out at high speed
What if you could watch a CT scan live, instead of analysing the images afterwards? If it is up to the Leiden mathematician Jan-Willem Buurlage, that will soon be a reality. He is developing methods to make the algorithms behind 3D scans faster. Quite a challenge: ‘Just like mathematicians, computers…

Spinoza prize for Jan Zaanen
Jan Zaanen, Professor in Theoretical Physics of condensed material, has been awarded a Spinoza prize. His pioneering ideas about the collective behaviour of quantum particles and high temperature superconductivity have often given him the reputation of being something of a rebel.

Re-education of Netherlands Indies children
In the late colonial Netherlands Indies, starting from 1892, homes were set up for the re-education of children. At first by private individuals, later by the government. Much later still, privately funded institutions existed alongside government-funded ones. Annelieke Dirks’ defence on 23 June 201…

Resolution of electron microscope greatly improved
The use of a new type of detector has generated a strong improvement in the resolution of electron microscopes. The 'low-energy electron microscope' (LEEM) can now be used for research on the thinnest possible materials. The tests with the detector represent the first result of the ESCHER project.

Seeing the Romans - and ourselves - in a different light
Globalisation means becoming globalised, a process in which material culture plays a crucial role. This is what Miguel John Versluys, the new Professor of Classical and Mediterranean Archaeology, teaches. He bases his teaching on research into the origin and growth of the Roman Empire from the 3rd…

Simone Buitendijk: ‘MOOCs are no hype’
Vice-Rector Simone Buitendijk doesn’t believe for a single moment that Massive Open Online Courses (MOOCs) are just hype. This is what she said on 13 March at Campus the Hague’s InspirationLab on ‘Open Education’. Buitendijk wants Leiden University to be at the leading edge. ‘MOOCs and online innovation…

New technique for Imaging Charge Transport in a Graphene Layered Cake
Leiden Physicists have developed a new technique to visualize electrical conductance in sheet-like nano materials. It shows great promise for devices based on a new family of materials—the ‘Van der Waals materials’. The physicists, who won the 2015 Dutch Vacuum Society prize for their work, present…
