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).…

An important feature of atopic eczema (AE) is a decreased skin barrier function. The stratum corneum (SC) lipids - comprised of ceramides (CERs), free fatty acids (FFAs) and cholesterol - fulfill a predominant role in the skin barrier function.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

In this thesis, we present new laboratory data of interstellar dust analogues.

The emissions of the Chinese industrial sector alone comprise 24.1% of global emissions (7.8 GtCyr−1 in 2015). This makes Chinese industrial emissions of unique national and international relevance in climate policy. This study reports a literature survey that quantitatively describes the evolution…

In surface science there is great effort to move from studying simple, flat model surfaces in vacuum to investigating more complex model catalysts in gas environments (in situ). This thesis gives three examples of such studies using microscopy and spectroscopy.

The minor consists of three courses in each period, and a group project running the whole semester. The first period starts off with the three-week course Anthropocene: The Planet of Man, which serves as an introduction into the subject as well as for building a community of students. This course is…

On 11 May 2016 a prestigious NWO Vidi grant (NWO's Innovation Research Incentives scheme) has been awarded to Nadia Soudzilovskaia for her research proposal entitled “Do mycorrhizal fungi mediate soil carbon fate?”, aimed to understand mycorrhizal impact on soil carbon sequestration.

The research article ‘Selection and Use of Manganese Dioxide by Neanderthals’ received 12421 article views in 2016, placing it as one of the top 100 read Scientific Reports articles in 2016.

Seagoing vessels may emit fewer and fewer harmful substances, but how do you measure whether they comply with the standards? The Dutch Environment and Transport Inspectorate (ILT) and the universities of Leiden and Wageningen are starting a joint study to detect the emission of sulfur and nitrogen dioxide…

An international team of astronomers have become the first in the world to detect isotopes in the atmosphere of an exoplanet. It concerns different forms of carbon in the gaseous giant planet TYC 8998-760-1 b. The research will be published in the scientific journal Nature on Thursday.

The aim of the research project is to get insight in the biostratigraphical age and the palaeoecological setting of the Schöningen sites and hominin behavior and subsistence during the late Lower Palaeolithic.

With his clever measuring methods Ignas Snellen – together with his team – was the first to detect carbon monoxide in the atmosphere of exoplanets. For his pioneering work the Leiden astrophysicist has been awarded the Spinoza Prize, the highest academic honour in the Netherlands. The prize of 2.5 million…

Institutions for Conflict Resolution in Leiden focuses on how the judiciary is able to prevent and solve problems.

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

How are the building blocks of life formed?

Day-to-day activities are important in the development of social identities, the establishment of social standing, and the communal understanding of societal rules. This perspective is broadly referred to as practice theory and relates to the power of an overarching social structure and the individual…

What would be the environmental performance of the Carbon4PUR technology at industrial scale in the future?

The research profile ‘Asian Modernities and Traditions’ (AMT) aims to raise the strength and visibility of research, teaching and dissemination on Asian studies at Leiden University.

Making sure our buildings are sustainable will contribute to Dutch and European environmental standards. Leiden University meets these standards in all its building projects.

Coordination chemistry is the chemistry of metal atoms

What if we start taxing carbon-intensive products such as electricity and gasoline, and at the same time compensate low-income households? Hauke Ward and colleagues did just that in a computer simulation for Peru, with a remarkable outcome. Not only does the approach tackle climate change, but it could…

An international team of astronomers has shown in a laboratory at Leiden University (the Netherlands) that methane can form on icy dust particles in space. The possibility had existed for quite some time, but because the conditions in space were difficult to simulate, it was not possible to prove this…

Environmental scientist Nadia Soudzilovskaia has been awarded the prestigious, international Bessel-Forschungs prize issued by the Von Humboldt foundation. This German award is issued to outstanding foreign mid-career scientists that collaborate with German researchers. ‘The combination of different…

Yuvraj Birdja converted CO2 to formic acid to store energy in a sustainable way, with different catalysts. With this new knowledge, scientists are a step closer in industrially converting CO2 to chemicals and fuels. This can help reduce CO2 emission and the greenhouse effect.

Population growth, economic expansion and the associated land use caused an increase in the number of bird species facing extinction and a reduction in carbon storage worldwide. These are the findings of an international team of scientists, also from the Leiden University Institute of Environmental…

Undoubtedly, climate change and increasing human populations will affect Africa’s wildlife – but how exactly? And what can be done to conserve nature? Michiel Veldhuis formulated five testable hypotheses of what might happen and now investigates how the UN Sustainable Development Goals can be achieved.…

The energy transition is a complex transformation process that is not only about technology -moving towards renewable energy sources-, but even more so about societal and institutional change. The energy transition requires and provides opportunities for actors to take on new roles.

This project, under the supervision of Prof. Dr. Hans van der Plicht, comprises several studies aimed at the use of isotopes occurring naturally in organic material as tracers for both the climate change and its cultural impact at about 6200 BC. The research will be carried out by the co-applicant at…

Leiden University has long history of research and teaching on Asian traditions, with a focus on language and philology, history, religious studies, philosophy, law and literature. Leiden has in the last thirty years also built up an equally impressive strength in the study of modern and contemporary…
