Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

The single cell group (SCG) is part of the Metabolomics & Analytics Centre Our research is centered around developing innovating analytical methods tailored for small-volume, or single cell analysis to enable metabolomics-driven systems biology in personalized health strategies. We are always on…

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

Diverse types of exoplanets such as gas giants on close-in orbits (hot Jupiters) and young massive giants on wide orbits (super Jupiters), with no analogs in the Solar System, pose challenges but also opportunities to our understanding of planet formation and evolution.

Within the MAC our Enabling Analytical Technology team is working to innovate all steps of analytical workflows. This includes developing novel sample preparation modules, creative sample handling methods, automated workflows, and more. Several projects implement the microfluidic principle of segmented…

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

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

This thesis presents a thorough survey of the central aspects of the phonology of Shaoxing Chinese from a synchronic perspective and on the basis of recent theoretical phonological developments, with the secondary goal of casting some light on current issues in Modern Chinese (Mandarin).

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

The new cabinet threatens to cut nearly a billion euros from higher education. This not only endangers academic work, it is a disaster for the Netherlands itself. The proposed penalty on study extensions and other financial measures will heavily impact students and will reduce education accessibility.…

During the pre-PhD phase the Dual PhD Centre collaborates with the candidate to find a suitable doctoral supervisor (Dutch: promotor) and graduate school. The doctoral supervisor has a critical role in the dissertation research process. Under his/her supervision, the candidate develops a dissertation…

One of the stained glass windows in the Great Auditorium of the Academy Building is dedicated to the students and staff of Leiden University who resisted, protested against, or became victims of the German occupiers. It depicts female figures alongside male ones.

The ambition of the Metabolomics and Analytics Centre led by Thomas Hankemeier is to develop innovative analytical strategies for metabolomics-driven health monitoring and systems biology studies. Understanding the intricate balance between health, disease and adaptation to challenges relies on the…

More than 600 staff members and students of Leiden University did not survive the war. Two of them were Caroline van Loen and Elsa Oppenheim .

Are there significant differences among the environmental impacts resulting form the production of Asian aquaculture commodities and what are the main causes for these?

An overview of all special issues published by The Hague Journal of Diplomacy.

LIAS PhD program activities include thematic coursework (the PhD Seminars), generic skills training, library training, research talks, social events, and so on. Skills training sessions and research talks are moderated by the Director of Doctoral Studies. All events are open to all LIAS PhD candidates,…

Research at the MCBIM group is comprised of the following research themes:

Lecture, China Seminar

The LUCL Labs consist of four spaces equipped to conduct high-quality experimental linguistic research.

The symposium is open to all registered participants and consists of a two-day programme and a poster session.

The mission of Software and AI in Business (SA&B)connects the domains of science, business, and policy. Scientific research we focus on at Leiden in areas such as artificial intelligence promises to reshape our societies for the better. Translating science into positive societal impact however requires…

Planets existing in other solar systems contain invaluable information about the origin of planets and life. PhD candidate Yapeng Zhang has studied their atmospheres by looking at their smallest parts: isotopes. With her research she hopes to discover what makes our own solar system unique.

Forum essays provide a framework for intellectual exchange and debate about the role of diplomacy around a particular theme. The essays are argumentative contributions and are shorter than research articles.

Wim Willems and Hanneke Verbeek were awarded with the Die Haghe Prize of 2016 for their book ‘Hier woonden wij. Hoe een stad zijn Joodse verleden herontdekt’ (English: ‘This is where we lived. How a city re-discovers its Jewish past.’) It is an exciting book about the rise and fall of the Jewish community…

Below is a chronological list of the most recent to oldest publication from the MultiGreen project.

Four bachelor courses are rewarded as Top courses.

We aim to provide new insights relating to the spectacular multi-cellular life cycle of streptomycetes and other actinobacteria.

Coordination chemistry is the chemistry of metal atoms

Twenty years from now, the world population is estimated to be around 9 billion people (now 8 billion). In combination with the improvements in living standards and the corresponding growth in consumption, this population will result in an enormous increase in the demand for food, consumables, water…

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

Corruption, integrity (or a lack thereof…) and public values are near omnipresent elements in public administration and politics of all times. Cases of corrupt public officials and politicians continuously emerge. Strangely enough, however, it often remains unknown what actually occurred, how something…

Describe and identify what dosimetry parameters are of importance to interpret dose-response relationships (eg., mortality, sub-lethal, growth or reproduction inhabitation, DNA damage and reactive oxygen species, etc. ) for metal-based nanoparticles? How to develop quantitative models that enable to…
