Ionic liquids are important in scientific research because they can apply a lot of charge over a surface. Leiden physicists have now found that the charging process of ionic liquids purely depends on opposite charges attracting each other. Chemical reactions are sometimes involved, but not essential.…

Research at the Catalysis and Surface Chemistry group is comprised of the following research themes:

We have recently discovered that there are biological proteins that phase separate out of solution much the way oil will de-mix from water (see movie). These form dense, liquid-like phases called protein condensates.

Turnaround Wing of INSOL Europe and Leiden Law School are working on the design of ‘guidelines for out-of-court turnaround professionals’. The project was approved by the Council of INSOL Europe at its 2014 conference in Istanbul and subsequently started in November 2014.

Self-censorship violates principles of a free society but few people want to take the role of the martyr.

Twenty years from now, the world population is estimated to be around 9 billion people (now 7.8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this will result in an enormous increase in the demand for food, consumables, water and energy.…

We work on projects commissioned by the European Commission, INSOL Europe and ELI (European Law Institute) as well as various other projects with an international scope. You can find our projects on the right. There have also been several important publications regarding TRI, also from our staff, that…

Can a new proteomics workflow be developed to link genes and gene clusters to bioactive molecules, identify novel compounds and enhance the production in the Streptomyces lividans enzyme?

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.

We aim to engineer streptomycetes to fully exploit their potential for natural product productions, by a rational design and evolution approach.

For the first time, physicists have visualized the ‘melting’ of electrons inside a special class of insulators. It allows electrons to move freely and turns the insulator into a metal and possibly later into a superconductor. Publication in Nature Physics.

Chemists developed a new graphene-transferring method which makes use of cyclohexane. This new method leaves less impurities on graphene, is easier to handle than current methods and is widely applicable in graphene research. The publication will be on the cover of the journal ACS Central Science late…

Nearly six hundred new first-year students visited their new faculty on 15 Augustus during the EL CID introduction week. They were welcomed at the Faculty of Science with a transmitter hunt, photo shoots, warm words and lots of liquid nitrogen.

A research into homicide.

Materials are either gas, liquid or solid, based on how their molecules respond to temperature and pressure. But what if the building blocks are self-spinning particles instead of ordinary molecules? Theoretical physicists found out what determines the phase of those artificial materials. Publication…

Professor of Law and Society Maartje van der Woude is searching for innovative ways to facilitate dialogue about topics that are usually experienced as ‘difficult to talk about’ – such as racism, ethnic profiling, exclusion, crimmigration – with a wide audience.

Liquid nitrogen, frozen fruit and levitating market-goers. On Friday 8 April, visitors to the weekly market in the Merenwijk district were exposed to superconductivity. What is it exactly? And what does it look like? Young and old were impressed by the experiments demonstrated by Leiden students from…

Nematic liquid crystals form the key ingredients of most tv screens. The active version of these complex fluids forms a useful model for physicists to research the responses of active matter—like bacteria or traffic flows—to mechanical and geometrical cues. An international research team publishes their…

On Thursday 15 February 2018, the Hazelhoff Centre for Financial Law welcomed Roel Janssen, financial and economic journalist and writer, for the fifteenth Hazelhoff Guest Lecture.

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.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

The ultimate aim of this project (initated by the European Law Institute) is to design a framework that will enable the further development of coherent and functional rules for business rescue in Europe.

The Biological- and Soft-Matter Physics Master specialisation is one of the two programmes Leiden offers in experimental Physics. The programme can to a high degree be tailored to individual needs and interests.

With each discovery that is made, the universe reveals a fraction of its secrets: the most distant galaxies and quasars, the atmosphere of exoplanets, evidence of dark matter, complex molecules in space. This is what fills the days and nights of the researchers from the Leiden Observatory and their…

A lecture about the drive, dynamics and dilemmas of our central bank and supervisor. Joanne Kellerman discussed the role of DNB, the central bank in our country for already 200 years, and the dilemmas that a supervisor faces. How can be ensured that a supervisory intervention is rightly timed and that…

The oldest university in the Netherlands has produced many well-known scientists. Some of them are known to the wider public; others are perhaps less well known, but their achievements are no less impressive.

A full overview of CASC PhD theses.

Jacques Sevat discussed the practical and legal aspects of global collateral management: collateral management to reduce the credit risks a global bank such as ING Bank runs every day.

New technology offers many new possibilities for research, such as on dementia. ‘Organ-on-a-chip’ is a new technology in which small bits of organ are grown out of stem cells on a small plastic plate. A small piece of blood vessel, heart or nerve offers many new possibilities for research, such as…

Metabolomicshas emerged as an important discipline to study molecular and cellular processes in living cells and organisms with the ultimate aim to obtain an answer to a given biological/clinical question.

The entrepreneurial spirit is highly present among the SBB students. The many (successful) spin-off companies from Leiden University brought by (former) SBB students are proof of this.

Undaunted by the corona crisis, Renske Donkers, a student of Molecular Science and Technology, conducted her bachelor’s research in collaboration with an international university. Her contacts with her supervisors at the University of Limerick, in Ireland, were all online. Donkers contributed to resolving…

Astronomer Frans Snik searches for extraterrestrial life. He doesn’t so much look at stars as at the ‘exoplanets’ alongside them.

To achieve societal impact, you need to do more than solely writing academic articles. That's the idea behind the Master Honours Class 'Leiden Revisited', in which students demonstrated with art how residents at the outskirts of Leiden experience the city. 'It's the perfect way to start the debate.'

Molecules are extremely hard to see in visible light, especially without using fluorescence. Leiden physicists have now made their optical technique sensitive enough to image the molecules of their interest in all sizes. Publication in Nanoletters.

Astronomers have discovered seven Earth-like planets around a dwarf star in our galaxy. Three of these planets are located in the habitable zone of this star, and may contain liquid water. ‘The next step is to study the atmospheres for signs of life. In Leiden we are experts in that area,‘ says planetary…
