On January 5, Rosa Winter will obtain her doctorate in arithmetic geometry. She researched solutions of equations that define so-called ‘del Pezzo surfaces’. ‘I like geometry because I can imagine and draw the shapes and objects,’ says Winter. ‘That makes abstract mathematics feel more tangible.’

Tiny self-propelling spheres, measuring only micrometers, move faster over a hydrophobic silicone surface than they do over hydrophilic glass. 'Almost nobody had realised that the substrate matters', says Stefania Ketzetzi, the researcher who discovered the effect, researched it and explained it. She…

Researchers from the THEOR CHEM group at Leiden University strive to set new benchmarks in the accuracy of the prediction of interaction energies between molecules and metal surfaces.

The Joan Van der Waals colloquium is an ongoing bi-weekly lecture series.

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

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.

The "Van Marum Colloquia" are a collaborative lecture series between the LION and LIC institutes, focusing on fundamental and applied surface science.

Leiden physicists have managed to detect a single molecule called dibenzoterrylene in a new crystal, and found that it is a candidate component for a quantum network. Future quantum computers will need such a network to work together while maintaining their advantages. Publication in ChemPhysChem jo…

It's pretty hard to spot a single 5 nanometer particle. Leiden physicists pulled it off by turning a 120 nm gold rod into a detector.

Caspar van den Berg was asked by Dutch news programme EditieNL for a reaction to the new coalition agreement and the ministerial team. Some ministries are set to have two ministers. Can that go well? View the excerpt.

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:

The stratum corneum (SC) plays a fundamental role in the barrier function of the skin. The SC consists of corneocytes embedded in a lipid matrix.

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

The Leiden Institute of Chemistry (LIC) is the basis for research and collaborations of the Leiden chemistry groups. Chemistry is the central science enabling a healthy future in a sustainable society. Chemistry researchers at Leiden University take a fundamental approach in finding tailored solutions…

We, as LUGO, believe that with simple everyday actions we can prevent large amounts of single-use plastic water bottles from entering our oceans.

A group of single-celled organisms organises its DNA in a similar way to higher organisms such as plants, animals, and fungi. However, the way packaged DNA is read out differs between the two related groups, Bram Henneman discovered. PhD defence on 5 December.

Scientists need individual photons for quantum cryptography and quantum computers. Leiden physicists have now experimentally demonstrated a new production method. Publication in Physical Review Letters on July 23rd.

This thesis explores different avenues to develop insurmountable antagonists for CC Chemokine Receptors, such as CCR1, CCR2 and CCR5.

The way genes are folded determines their activity in our body. Leiden biophysicists are now the first to unravel this structure molecule-by-molecule. Publication on December 1st in Nature’s Scientific Reports.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

The current hepatitis B vaccines need to be stored and transported under refrigerated conditions (2-8 degrees C). This dependence on a cold-chain is highly challenging in areas where hepatitis B virus infections are endemic.

Light can be used to apply forces on single cells. Focused lasers have been used by physicists to tweeze particles and to manipulate them. These so called “optical tweezers” can be used as mechanical phenotyping tools for characterising the mechanics of materials and living objects.

On 24 September the Institute of Environmental Sciences (CML) in Leiden will launch the new version of the Pesticides Atlas in cooperation with Rijkswaterstaat and Royal HaskoningDHV. The online tool is now faster, more user-friendly, more accessible and all data can be downloaded directly. Users can…

Living cells on topographically-controlled substrates: Understanding Cell Motility in a Quasi-3D Environment

How is energy really dissipated on the atomic scale when sliding objects slip over a single lattice spacing?

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

Metal complexes and 2D materials like graphene were combined to produce structures that can function as sensors.
