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

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

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…

In this thesis, we describe the latest advances in SQUID-detected Magnetic Resonance Force Microscopy (MRFM).

The theoretical explanation of cosmic acceleration is nowadays one of the biggest puzzles in cosmology.

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

The specialisation High-Tech Innovation is for MSc students in Sciences who are interested in interdisciplinary technologies and research related to /important for high technology industries, e.g. the semi-conductor industry or nano-fabrication. In addition to their primary field of study, students…

The Algorithms and Software Technology (AST) research programme performs fundamental research in the areas of algorithm design and analysis.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

The research of the Algebra, Geometry and Number Theory cluster tries to bridge the gap between abstract theory and the world of algorithms and applications.

Artificial photosynthesis aims to produce fuels from solar energy using chemical processes. In semi-artificial photosynthesis, a hybrid approach is taken using both chemical and biotechnology approaches. We aim to develop hybrid systems between light-harvesting nanoparticles and redox-enzymes (oxidoreductases)…

Leiden University offers you several services related to career orientation and job application skills.

In this thesis we study the landscape of gravitational models which modify GR by introducing an additional scalar degree of freedom (d.o.f.) to source Cosmic Acceleration.

This thesis focuses on developing wafer-scale two-dimensional (2D) materials by combining synthesis, transfer, characterization, and device integration of graphene, hexagonal boron nitride (h-BN), and BN-doped amorphous carbon.

A novel in vivo model system for studies on glucocorticoid resistance

Moving an electron microscope of 2000 kg is a delicate challenge. The highly sensitive instrument needed to be moved to a new measurement hall, but even a tiny bump could damage it. After a few nerve-racking weeks of preparing the move and reinstalment, the researchers finally have a verdict: the instrument…

From a meaningless block of plastic to an advanced component that contributes to the energy transition. The technicians and scientists of our faculty think it out in detail and make it a reality. This special project shows that they need each other.

Following in the footsteps of Professor Jan Zaanen, visiting fellow Louk Rademaker is exploring quantum effects in so-called strange materials. His research is paving the way for new materials that could be used in emerging technologies.

Leiden physicists have developed a way to address how accurately a superconducting single photon detector (SSPD) can be characterized by detector tomography. SSPDs are not fully understood, and tomography is a key element to determine how these devices detect light. A better understanding of these detectors…

When you imagine a scientific conference, you might think of endless presentations and coffee breaks. But at the Lorentz Center in Leiden, things are a little different. Here, scientists don’t just listen—they collaborate, debate, and design the future of their field.

Ten years after its introduction, the controversial idea of Erik Verlinde on gravity is still a hotly debated topic, and is still surrounded by a cloud of scepticism. Scepticism in which the media have played a major role, theoretical physicst Koenraad Schalm says in an article by NWO. ‘The media simply…

The aim of the research project is to get insight in the biostratigraphical age and the palaeoecological setting of the Schöningen sites and hominin behavior and subsistence during the late Lower Palaeolithic.

A month ago it was Marc Baggelaar, and now Hans Kistemaker too has obtained his PhD cum laude at the Leiden Institute for Chemistry (LIC). ‘He has made ground-breaking contributions to the world of protein modification,’ says PhD supervisor Gijs van der Marel. Kistemaker obtained his PhD on 11 May…
