Ancient Charm
The aim of ANCIENT CHARM was to develop neutron-imaging techniques and the associated equipment, and help establish neutron imaging as a mainstream archaeological analytical technique. In particular, one of the goals was a new imaging technique which called neutron resonant capture imaging combined…

The interplay between stars, gas and dust in faint star-forming galaxies
When observing star-forming galaxies, we are not only seeing stellar light, but we also see how this interacts with galactic gas and dust. This thesis contains studies of the stellar, nebular and dust properties of low mass star-forming galaxies.

The electrochemical reduction of dioxygen and hydrogen peroxide by molecular copper catalysts
The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Electrocatalytic CO2 reduction toward liquid fuels : on heterogeneous electrocatalysts and heterogenized molecular catalysts
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.

Report: what does our urban mine have to offer?
On 21 January, the Institute of Environmental Sciences (CML) has released two reports on circular economy and urban mining in the Netherlands. In them, together with Statistics Netherlands, they take stock of part of the Dutch ‘urban mine’: how much raw material can we reuse from the electricity grid,…

René Kleijn appointed Professor of Resilient resource supply
The energy transition ranks high on the European policy agenda, but what does it take to get there? René Kleijn researches how we can extract, use and reuse raw materials in a responsible way. Since 1 March, he has been appointed professor of Resilient resource supply.

The city as an urban mine
Raw materials should no longer be excavated from mines, but reused from sources that are already present, such as unused underground electricity cables and discarded ships. At least, that is necessary for a circular economy. A new report explores where these resources are located and how we can use…

‘The almost impossible task of being both artist and observer'
How can artist PhD candidates research their own work? They need to be good at switching from maker to critical observer and their research has to have a solid theoretical basis. This is the premise of Professor Janneke Wesseling. The aesthetic value of their work also has to be up for discussion. Inaugural…

LDE minor focuses on resources needed for energy transition
European dependence on Russian gas, earthquake damage in Groningen and the changing climate: the call for an energy transition is getting louder. This transition will be accompanied by an increasing demand for 'new' raw materials. The Geo-Resources for the Future minor looks at exactly that developm…

Superconductivity theory under attack
Measurements on a superconducting material show an abrupt transition between a normal metal and a 'strange' metal. The really strange thing, however, is that this abruptness disappears when the temperature falls. 'We don't have any theoretical machinery for this', says theoretical physicist Jan Zaanen,…
