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…

A network combining 9 academic research groups and 4 collaborating industrial companies will train the next generation of PhD students and post-doctoral researchers, in developing and applying novel experimental and theoretical methods in the NMR spectroscopy of systems containing paramagnetic metals.…

Leiden has a strong tradition in theoretical physics, thoroughly linked with experimental disciplines.

A lot of our research is performed at temperatures close to absolute zero, among other reasons because this increases the sensitivity of the measurements. 

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

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.

From nanoparticles to colliding ice planets and from biological origami to new x-ray scanner techniques: this year again, our scientists have made wonderful discoveries. From the largest numbers to the smallest molecules and from the oldest galaxies up to the latest algorithms, take a look at each institute's…

Metal-based prodrugs based on ruthenium(II) polypyridyl complexes have proven to be very suitable for application in both photodynamic therapy (PDT) and photo-activated chemotherapy (PACT).

To get an idea of the science communication products and research that is possible, a few examples of student projects of recent years are shown below.

Since the early 1990s, one can isolate the optical signal of a single molecule and single-molecule spectroscopy has quickly grown into an important research field.

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)…

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars, which are called exo-planets. They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems.…

Combining different disciplines, researchers work together to formulate innovative solutions to societal problems.

The research group Science Communication and Society has been physically within the Institute of Biology (IBL) since 2012 and has become a formal part of the institute in 2018. The mission of this group is understanding how science communication works to improve the interaction between science and s…

SALTSWAT -- a project which combines the Spaces for Active Learning & Teaching and the Support wtih Active Teaching -- began in Mid-2019 and is running in pilot until the summer of 2020. The purpose of the project is to find answers to the question of how to systematically accelerate 'active teaching…

An overview of awards and prizes granted to our staff and students in 2021, as well as special appointments at Leiden University and other institutions.

Physicist Remko Fermin from Leiden University was awarded a Rubicon grant from NWO. He will use it to study superconducting diodes that could contribute to reducing the CO2 emission of data centres.

Julia Cramer is the winner of NWO's Minerva Prize for 2017. Cramer will receive the prize for her research in the field of quantum science and technology.

Stefano Pollas master thesis 'Quantum Digital Cooling' has been awarded the Lorentz Master thesis award. The award, 3000 euros and a certificate, has been awarded on 25 November at the Koninklijke Hollandse Maatschappij van Wetenschappen (KHMW) society in Haarlem.

The Leiden Institute of Physics (LION) is the coordinating partner in the Qluster research project, which was awarded a 2,9 million euro FET Open grant by the European Union. The three-year project, which started on 1 December 2019, aims to produce many photon entanglement to aid quantum communication…

Five researchers from Leiden University have been awarded a Starting Grant by the European Research Council (ERC). This grant of on average 1.5m euros enables researchers who show potential to start their own project, lead a research team and implement their best ideas.

Physicist Jelmer Renema will spend two years conducting research at Oxford University in Great Britain funded by a Rubicon grant from NWO.

This year, two Leiden physicists have earned a prestigious ERC Starting Grant. With a budget of 1.5 million euros, this is one of the largest individual grants for scientists.

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.
