Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Promotor: Jan van der Greef; Co-promotors: Mei Wang; Eduard van Wijk

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…

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).…

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

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,…

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

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.

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

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…

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…

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

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 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.

As a new vision on food production, the feasibility study on LED light to grow crops with the biological- and chemical evaluation of final products.

The major and ultimate aim of metabolomics is to obtain an answer to a specific biological or clinical question.

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…

Nonparametric Bayes for high-dimensional models: contraction, credible sets, computations

In this project we develop algorithms to automatically detect a particular type of archaeological sites in satellite images of the Alps.

This monograph focuses on clustering of objects in high-dimensional data, given the restriction that the objects do not cluster on all the attributes, not even on a single subset of attributes, but often on different subsets of attributes in the data.

This thesis develops statistical methods for the analysis of high dimensional data: high dimensional networks reconstruction (Chapters 1-4), incorporation of prior information in networks reconstruction (Chapters 2-4), incorporation of prior knowledge in genetic association studies (Chapter 3).

Advancing the understanding of the interaction of light and matter on the single-quantum level is important for near-future quantum technologies but also to answer fundamental questions.

How do humans control their thoughts and actions, and what can high-field brain scanning reveal about the underlying processes?

Transcutaneous vagus nerve stimulation (tVNS) was tested in chronic worriers. tVNS may reduce spontaneously occurring negative thought intrusions. After a worry induction, there was no longer an effect of tVNS. tVNS did not affect physiological responding to worrying.
