The Leiden Institute of Physics hosted the annual conference of the Dutch Vacuum Society (NEVAC). Experts in the field of vacuum experiments talked about their research. The 2016 NEVAC Prize was awarded to PhD student Martijn Vos from the TU Eindhoven.

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…

We simulate interstellar clouds with special plasma expansions and chemical reactions on icy dust grains to be measured in ultra-high vacuum setups. This provides the data necessary to guide and interpret astronomical observations and to model reaction networks in space. [Harold Linnartz]

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…

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

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.

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

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.

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.

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

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

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).…

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.

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

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…

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.

For the first time, scientists have traced back a high-energy neutrino to its source in space. It was produced by a so-called blazar—a supermassive black hole. Researchers from neutrino detector IceCube report this in Science. ‘This is a milestone for neutrino science,’ says physicist Dorothea Samtleben…

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…

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

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

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,…

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…

Three projects with Leiden researchers are to receive a subsidy from NWO for the construction or renovation of large-scale research facilities. They will be working on electron microscopy, an X-omics initiative and an X-ray telescope. The projects are part of the National Roadmap for Large-Scale Scientific…

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.

Professor Barend Mons has been appointed Chair of the Commission High Level Expert Group "European Open Science Cloud", initiated by the European Commission, DG Research and Innovation.

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).

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

Liposomes hold great promise for peptide-based personalized cancer vaccination, especially when administered intradermally. However, current liposome preparation methods are very time consuming (resulting in long development times per formulation), whereas personalized cancer vaccination requires very…
