On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

The study by Tahir Abbas and Liselotte Welten reveals a structural and nuanced understanding of how the question of Salafism in the Netherlands has become an increasingly discussed phenomenon and the types of threats that ought to give genuine concern to security, intelligence and policing services.

An Integrative Approach to the Hominin Record

The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

With the help of quantum mechanics, digital quantum hardware may be able to tackle some of the problems that are too difficult for ordinary computers. But despite these expectations and the ongoing effort of the research community, reliable quantum computers are not yet realized in a lab setting.

AI Labs are collaborations of Leiden University with external parties such as industry, governmental parties and other universities on the topic of Artificial Intelligence. The Science institutes of Leiden University are unique located in the largest Bioscience Park of the Netherlands, next door to…

This thesis describes the design, characterization and application of dextran based crosslinked network.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Leiden University wants its research and teaching to have a positive impact on society. In an effort to achieve this, many of our researchers collaborate with academic and community partners, non-governmental organisations and the business sector.

The Physics and High-Tech Innovation specialisation consists of 120 European Credit Transfer System (EC) points and includes a physics component (60 EC), mostly in the first year, and a High-Tech Innovation component, mostly in the second year (60 EC).

Detection of cerebral beta-amyloid (Abeta) by targeted contrast agents remains of great interest to aid the in vivo diagnosis of Alzheimer's disease (AD). Bis-styrylbenzenes have been previously reported as potential Abeta imaging agents.

Seasonal influenza vaccines provide protection against matching influenza A virus (IAV) strains mainly through the induction of neutralizing serum IgG antibodies. However, these antibodies fail to confer a protective effect against mismatched IAV. This lack of efficacy against heterologous influenza…

In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

Assessing the risks of engineered nanomaterials (ENMs) solely on the basis of experimental assays is time-consuming, resource intensive, and constrained by ethical considerations (such as the principles of the 3Rs of animal testing). The adoption of computational toxicology in this field is a high p…

The Bachelor's degree trains future computer scientists in the fields of Data Science and Artificial Intelligence. When you graduate you will be ready for a range of career options.

It is generally accepted that a university education is about more than knowledge transfer alone. Alongside knowledge and understanding, students should develop the skills required to apply this knowledge and understanding.
