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).…

With increasing carbon dioxide levels in the atmosphere and their detrimental effect on the global climate, modern society needs to push for more renewable energy sources. Storing widely accessible and abundant solar energy in chemical bonds in the form of molecular fuel via artificial photosynthesis…

Isotopic insights on human diet from the later stone age to Neolithic in Northwest Africa, Morocco

This thesis revolves around the electronic spectroscopy of molecules in the laboratory and the search for the carriers of the diffuse interstellar bands (DIBs).

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…

Patterns of paleomobility in the Caribbean were studied through an inter-disciplinary approach using a combination of archaeological, osteological, mortuary, and isotopic data.

In this dissertation iron-based homogeneous catalysts were synthesized, characterized and investigated for water oxidation activity.

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.

The external tissues of plants and animals are colonized by microbial communities termed microbiota. When organisms are exposed to environmental pollutants, these substances will therefore encounter microbiota at the exposure interface.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

In this work, we illustrate unconventional approaches towards the fabrication of edge functionalized graphene nanostructures and bidimensional architectures in polymeric and metallic supports, with an outlook towards molecular sensing devices.

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

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

Engineering an efficient microbial enzymatic polyethylene degradation pathway via an innovative combination of biochemistry and computational biology tools for enzyme discovery and characterization.

This project consists of various case studies.

Streptomyces are prolific producers of enzymes and secondary metabolites, including more than 50% of all clinical antibiotics. This makes them highly attractive for medical, biotechnological, and industrial purposes.

MICRO-biome climate smart applications: Can we use indigenous microbial rice communities to reduce methane production in agricultural settings?

One of the key discoveries in exoplanet research over the past decade is the abundance of small planets in our Milky Way. Despite their high numbers, our understanding of their atmospheres remains limited, and it is unknown if they possess atmospheres at all.

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

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.

Global Environmental Extensions Multi-Regional Input-Output (EE-MRIO) analysis is often used to analyze how changes in global and national demand for products lead to socioeconomic and environmental impacts at the national level.

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

The expanding population and economic activity are driving up global energy consumption. Simultaneously, there is an urgent need to transition from fossil fuels to renewable sources to mitigate the climate crisis, primarily caused by fossil fuel combustion.

This article argues that opposition to government green investments is conditional on the method of financing.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

Watch and talk along with today’s science of the past during weekly Let’s Plays of popular games and vodcasts on the livestream platform Twitch.

How did digital intermediality symbolise and facilitate the transfer of content from popular culture into policy statements and vice versa in the period between 1945 and the new millenium?

The project investigates epistemicity: how the knowledge of the speaker and hearer can be expressed in the grammar. This shows us how speakers organise their knowledge, and whether this is influenced by the language they speak.

Research on the process and construction of news stories about human rights issues in Latin American newspapers.

Amy Strecker assesses the institutional framework for landscape protection, analyses the interplay between landscape and human rights, and links the etymology and theory of landscape with its articulation in law.

This PhD project investigates how nationalist ideas are expressed, shaped, and negotiated in Moroccan Malhun poetry in the nineteenth and twentieth centuries.

The Centre for Digital Heritage undertakes collaborative international research in the field of Digital Heritage. It is an initiative of the University of York.

How did local lifeways and crafting practices persist and develop in the diverse environments of the increasingly interconnected Gulf of Fonseca (AD 400-1521)?

The project investigates how bilingual speakers navigate lexico-syntactic features, including grammatical gender, classifier systems, and the linear order of adjectives and nouns, across Spanish and Chinese in both unilingual and bilingual contexts.

How do we create an environment for scientists to flourish in, while facing the challenges of the 21st century?

With the launch of the Albabtain Leiden University Centre for Arabic Culture, Leiden University and the AbdulAziz Saud Al-Babtain Cultural Foundation will join hands in promoting the understanding of Arabic culture. Have a look at the centre's plans for the years ahead.

This week more than 400 international students are starting their study programme in Leiden or The Hague. Why did they choose to study here? And what is the advice from their mentors?
