After almost four decades, Leiden and Eindhoven chemists have resolved the discussion about the correct model for the simplest chemical reaction in heterogeneous catalysis, which is essential for fuel cells. Using a unique curved platinum surface, Ludo Juurlink and PhD candidate Richard van Lent from…

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

A major goal of ABS research is to overcome one of the major bottle-necks in metabolomic research: the lack of a high-throughput infrastructure in which thousands of samples can be processed in a standardized and cost-effective way (max. a few tens of Euro’s per sample for a full metabolome profile).…

The life of a fibroblast is heavy, but PhD student Julia Eckert makes it 19.5 times heavier, using the Large Diameter Centrifuge at the ESTEC space research centre in Noordwijk.

The thesis introduces three methods for high-dimensional prediction problems in the biomedical field. The methods make use of empirical and variational Bayes in the estimation.

To study how planetary systems come into existence we study much younger systems still in formation.

A high performance computer or supercomputer owes its massive processing capacity to the fact that it chops a single overarching task into a whole series of smaller tasks. It simultaneously tackles each of those smaller problems.

Is EU law still supreme? Most national high courts have formulated some limits on the absolute supremacy claimed by EU law.

There is an urgent need for more physiologically relevant cell culture methods to guide compound selection in pre-clinical stages of the drug development pipeline.

High Performance Computing previously the domain of theoretical scientists and computer and software developers is becoming ever more important as a research tool in many research areas. A University facility, providing serious computational capabilities, combined with easy and flexible local access,…

It appears to be a paradox: ultra-thin material that absorbs all the incident light. Nonetheless, it does exist. Two Leiden researchers report on their research in ‘Applied Physics Letters’. The article is among the Top 20 of the most downloaded articles of this reputable journal in May.

The reintegration of high profile ex-offenders frequently receives great political and public attention. While this attention, more often than not in the form of negative sentiments, may be understandable from a moral perspective, it raises several important questions: how do such offenders reintegrate…

Employees are laying down their work in various sectors, such as regional public transportation and Dutch postal service PostNL. Inflation appears to be increasing dissatisfaction about working conditions, thinks Barend Barentsen, Professor in Labour Law at Leiden University. ‘It's the final straw.’

Can chemical safety assessment be improved with zebrafish embryo-based reporter assays?

The challenge of achieving fast quantification in metabolomics is the presence of severe matrix effects during the MS analysis of complex samples.

Astronomers led by Leiden astronomer Sebastiaan Haffert have directly imaged two planets that are gravitationally carving out a wide gap within a planet-forming disk surrounding a young star. While over a dozen exoplanets have been directly imaged, this is only the second multi-planet system to be p…

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

How can zebrafish research help to understand and fight human cancer?

We organise various activities for high school students and their physics teachers to learn about Astronomy at Leiden University.

We have studied shape with a particular focus on the zebrafish model system. The shape is an essential appearance of the phenotype of a biological specimen and it can be used to read out a current state or response or to study gene expression.

This thesis examines silicon pore optics (SPO), a technology that exploits silicon wafers from the semiconductor industry to create extremely high quality X-ray optics, by studying its manufacturing process, applications, and prospects.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Modern computer-aided simulation tools used by various industries produce gigabytes of data. But currently, they take days and even up to weeks of computation effort. To make the best use of all these data, the DAMIOSO project focuses on developing algorithms and tools for managing, mining, and optimizing…

For present purposes, it is important to distinguish between an early period of settlement, about 6800-6200 BC, and a late period, about 6200-5800 BC, at Tell Sabi Abyad.
