The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

Hydrogen peroxide (H2O2) generation via electrochemical oxygen reduction is a sustainable production method for this bulk chemical. However, the selectivity of molecular catalysts for electrochemical H2O2 generation has hardly been investigated in a systematic manner, and it is unknown if their stability…

Macromolecular Biochemistry is a section of the Leiden Institute of Chemistry at Leiden University, comprising the PIs Marcellus Ubbink, Remus Dame, Aimee Boyle, Lars Jeuken and Anne Wentink.

How can we understand the material instability of photographic (mixed media) artworks (1960s - present) from an integrated approach of Art History, Conservation Science and Chemistry in order to preserve these works for the future?

Vibrating carbon monoxide molecules adsorbed at the surface of a salt crystal stop moving after a few milliseconds. Scientists now discovered this is dominantly due to the emission of electromagnetic waves. The role of the chemical bond at the surface thereby appears to be less important than previously…

Here you will find an overview of the Spaces for Active Teaching and Learning already implemented at Leiden University and LUMC. These rooms vary in size, location, material affordances, and technological affordances, and thus vary in the forms of pedagogy they best support. You can use this site as…

Astronomer Donggang Wang, physicist Anne Meeussen and chemists Nick Gerrits and Elliot Mock: all four are receiving a Rubicon grant from the Dutch Research Council (NWO). This grant for young talent will enable them to spend two years doing research at a foreign university.

Assessing the effects of landscape and land-use changes on the visibility of archaeological landscapes in Central-Southern Italy.

Is it possible for sugar patterns on cells to activate the immune system to combat cancer?

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

Because of their large surface area and immunological competence, mucosal tissues are attractive administration and target sites for vaccination.

Recent studies of Neandertal body mass and skin surface indicate raised energetic requirements in this lineage compared to anatomically modern humans.

Our cantilevers have a low intrinsic damping rate: this enables us to measure with low noise, since damping is proportionate to noise. However, when the magnet is close to the surface of a sample we want to study, we measure a much higher effective damping rate. This is caused by magnetic interaction…

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

In this thesis unconventional tools based on fluidic interfaces were developed to study the surface and interfacial chemistry of graphene, to characterize the intrinsic properties of graphene, to disentangle the effects of substrate and of the environmental factors, and to improve handling protocols…

A 24 person classroom on the ground floor of PJ Vethgebouw. Rolling, flexible furniture and 5+ writable surfaces supports small groupwork. Furniture is interlocking, supporting multiple arrangments. Features a smartboard TV monitor. Bookable through ZRS.

The Faculty of Science launched the new Academic Year on 21 September with a special We Are Science talk show. Dean Paul Wouters starred in his role as talk show host and received a wide variety of guests.

Climate change is one of the largest challenges faced by humanity. To combat this research into alternatives to fossil fuels is ongoing. Dihydrogen is considered a good alternative fuel, since its burning only forms water.

Research training projects in the MCBIM group - Bachelor and master students of all chemistry related studies are more than welcome to take part in our research activities. We have various research projects, all in one way or another involving transition metal ions. Daily supervision in the laboratory…

This PhD-thesis presents a study on micron-sized particles, so-called colloids. By controlling the chemical and physical properties of these particles, such as the interparticle interaction and the particles’ shape, colloids can act as building blocks that self-assembly into larger structures.

SMR can be used to measure the mass of adsorbed protein to nanoparticles with a high precision in the presence of free protein.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

To study how planetary systems come into existence we study much younger systems still in formation.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

A technique originally developed for satellite imaging can now be used to recover pictographic texts from underneath the surface of a five hundred year old Mexican manuscript.

On the second floor of the Lipsius building is room 2.17, an active classroom designed with a capacity of 24 for active, group-based classwork. From 2019, the room will be part of the ZRS system and can be booked by the Humanities faculty and Humanities Service Desk.

Leiden astronomers and ecologists are developing an instrument that lets people measure the quality of surface water with a smartphone.This international citizen science project, MONOCLE, is a collaboration between scientists and local people in Tanzania, Brazil and four European countries.
