Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

This thesis investigates the relations between metabolism and anatomy through the use of Magnetic Resonance Imaging (MRI).

The doors of the new Gorlaeus Building are officially open! With an additional lab wing, new lecture halls and offices, a library, a brasserie, and spaces for student associations, the building offers a vibrant and inspiring environment for research, study, and social interaction. Explore on your…

The transition to new and renewable energy sources should be completed by 2050. Researchers in various disciplines at Leiden University are conducting unique research that will help us make this transition and reduce CO2 emissions.

Leiden physicists have been awarded 1.5 million euros for developing a hybrid microscope that provided nanometer-resolution. 'The idea is to combine the resolution of electron microscopy with the pros of optical microscopes.'

How can zebrafish research help understanding human diseases?

Nature is a never-ending source of inspiration for the researchers at the Institute of Biology Leiden (IBL). Based on a better fundamental understanding of nature, they are able to seek solutions in the area of health and biodiversity. The theme of IBL is ‘Harnessing biodiversity for health.’

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

For each living organism health is ensured by correct functioning of its cells. Cells therefore have elaborate methods for regulation of their proteins.

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…

The Leiden Institute of Chemistry (LIC) is to be joined by a further two talented young chemists. Bela Bode and Michele Pavanello have each won a Marie Curie subsidy. Bode will be studying electron transport in photosynthesis and Pavanello will be using computer models to study charge transport in large…

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

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)…

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

The Royal Netherlands Academy of Arts and Sciences (KNAW) selects prominent researchers as members based on their scientific achievements. On September 17th, the KNAW will install 21 new members, including Leiden physicist Michel Orrit.

Our facilities cover:

Our Division has created and maintains the Visualisation Core Facilities of the LACDR. This is a multi-user facility offering basic and advanced microscopic techniques to scientists of the LACDR.

How can you use robots and automatic recognition of microscopic images to test the effect of drugs exceptionally quickly?

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

Theorists have recently made substantial progress in simulating reactive molecule-metal surface scattering but still face major challenges. The grand challenge is to develop an approach that enables accurate predictive calculations of reactions involving electronically excited states with potential…

Triplet superconductivity refers to a condensate of equal-spin Cooper pairs (pairs of electrons with equal spin).

An objective of this research was to achieve direct, well-defined and non-rate-limiting electron transfer between respiratory enzymes and the electrode surface by means of 'Q-wires'.

Electrons in graphene behave like light particles; they have no mass and can penetrate everything: very useful if you dream about nano-electronics. But you do have to channel them. Carlo Beenakker will be researching how. He has been awarded an ERC Advanced Grant of 1.5 million euro to carry out this…

How do you make a technology sustainable that does not even exist yet? Well, by bringing together an interdisciplinary team of pioneering European experts right at the start and paying attention to sustainability right from the development phase.

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

The quantum nature of matter and light has grown into a broad and fruitful research field for theorists and experimentalists alike. It combines foundational research with toward applications, the most well known of which is the quantum computer.

MRFM combines the principles of magnetic resonance and atomic force microscopy.

Tuberculosis causes 1.5 million deaths yearly and anti-tuberculosis therapies are threatened by emergence of drug resistance. Development of innovative drug combinations should be accelerated with the use of translational pharmacological models. Moreover, host-directed therapies (HDT), which stimulate…

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…
