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…

The growing demand of energy indicates that global energy resources in the form of fossil fuels will not be sufficient in the future. In order to solve potential future energy problems development of a sustainable hydrogen economy is highly desirable.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

Aiming to advance the development and deployment of a scalable, safe, and integrated hydrogen infrastructure to support the energy transition.

This project aims at determining the market value of hydrogen peroxide (HP) that is produced via our electrochemical methods that have been developed as part of the ERC-StG Cu4Energy project.

What does it mean to protect against disaster in the context of climate change and other cascading environmental crises?

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

At Leiden University we like to stay in touch with our alumni. We therefore invite you by post, email or phone to lectures, workshops and masterclasses for alumni and inform you about developments in your field and at the University. With your knowledge and experience, you also make a valuable contribution…

Scientists have long been puzzled why it is easier to produce hydrogen from water in an acidic environment than in an alkaline environment. Marc Koper comes with an explanation: the reason is the electric field at the surface of the catalyst, which is larger in an alkaline environment, as he writes…

In this policy paper, Joachim Koops and Christian Patz are discussing Germany’s comprehensive assessment of Protection of Civilians readiness at the national level.

The thesis focuses on synthesis strategies in oligosaccharide campaigns, and the influence of protecting groups.

On 13 September 2023 Eline Scheerlinck successfully defended a doctoral thesis and graduated.

The expansion of the fund industry has been one of the most notable trends in the financial markets of recent years.

It is one of the energy carriers of the future: hydrogen. But how can hydrogen be produced in a sustainable way? With over 50 million euros in funding from the Netherlands Organisation for Scientific Research(NWO) and industry, a research project involving 58 partners from both the Netherlands and abroad…

Leiden chemists Marc Koper and Ian McCrum have discovered that the degree to which a metal binds to the oxygen atom of water is decisive for how well the chemical conversion of water to molecular hydrogen takes place. This insight helps to develop better catalysts for the production of sustainable hydrogen,…

This research project explores themes related to the system of close protection and surveillance (Dutch: bewaken en beveiligen) in the Netherlands.

ChEMBL is a large-scale drug discovery database containing bioactivity information primarily extracted from scientific literature.

On 23 April, Andreas Häuselmann defended the thesis 'EU privacy and data protection law applied to AI: unveiling the legal problems for individuals'. The doctoral research was supervised by Gerrit-Jan Zwenne and Bart Custers.

This research project from Leiden University looks at the opportunities and threats that flow from the existence of institutional and normative diversity in the area of fundamental rights for the effective protection of those rights in a pluralist world.

On Wednesday 13 December 2017 Jaap Wieland defended his doctoral thesis entitled ‘De bescherming van concurrentiebelangen in het bestuursrecht’ (the Protection of Competition Interests in Administrative Law).

New and reemerging infectious diseases call for innovative and efficient control strategies of which fast vaccine design and development represent an important element.

In this publication, May Tamimova and Tahir Abbas researched the existing literature about violence and hatred against places of worship.

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…

A consortium including economists, psychologists and public administration scholars from Leiden University will study public acceptance of the hydrogen transition in the Netherlands. They will look at the labour market impact, public perceptions of hydrogen and businesses’ willingness to invest.

The future of Europe as a community of democratic states is deeply uncertain. The European Union, founded to promote ‘ever closer’ integration, aims nominally for peaceful, prosperous cooperation. But this ideal has been battered by a series of bruising crises, and now by war.

Atherosclerosis, in particular rupture of atherosclerotic plaques, is the underlying cause of most heart attacks or strokes and is the leading cause of death worldwide.

Atherosclerosis is the most important underlying process that drives cardiovascular disease, and is characterized by an accumulation of cholesterol which triggers an inflammatory response in the vessel wall.

Atherosclerosis is a chronic inflammatory disease affecting millions of people world-wide.
