Natural resources are becoming increasingly scarce. If we want to maintain our current standard of living, we will need inventive solutions. The researchers at the Institute of Environmental Sciences (CML) share their thoughts on how to achieve a fully circular economy in which as little use as possible…

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

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…

Many metalloenzymes that are key to bioenergetics are membrane enzymes, with canonical examples the complexes I, II, III and IV in the mitochondrial inner membrane. To study these enzymes in a native-like lipid membrane environment, we aim to develop novel bioelectrochemical techniques.

Roll your sustainable sleeves! Our students and staff have found various ways to do just that, both at home and at our university.

The chemical industry must continue to innovate for a more sustainable, healthier society. The reseachers from the Leiden Institute of Chemistry (LIC) contribute by applying their knowledge to themes such as sustainability, energy and health.

The group of Dr. Roxanne Kieltyka designs and synthesizes molecules that self-assemble into polymeric materials using specific non-covalent interactions. These substrates can be used for numerous applications in medicine ranging from disease detection to cell delivery depending on the (bio)molecular…

Plant Sciences' contribution to the Bioactive Molecules research theme is to identify new plant bioactive molecules, and unravel their mechanisms of action in plant development or health, and the regulatory networks and (bio)synthetic pathways required for their production.

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

How will we celebrate our anniversary in 2025?

This minor critically examines the complexities of food sustainability through ecological, socio-economic, political, and cultural systems.

Many astronomers suspect that most of the matter in the universe is invisible. So how can you weigh dark matter if you can't actually see it? Professor Henk Hoekstra is looking for a solution. Inaugural lecture 25 June.

Room 4.28 in the LMUY Building is a dedicated lecture room for the Media Technology MSc program. Finding it for the first time may be challenging. Below is a description of how to find it.

The narrow but long stretched stript of Frisian land along the North Sea was already occupied before Roman times. However, man repeatedly suffered setbacks when he tried to extend his living space, both in the tidal marshes and the peat area south of them.

Adverse drug reactions (ADRs) remain one of the major reasons for patient mortality and (early) drug withdrawal. Currently, different in vivo and in vitro models are used to assess the toxic potential of drugs in the pre-clinical phase. Unfortunately, the predictive value of this model does not fit…

The research at the Living lab attracts a great deal of press attention. Please find below a small selection of the many news reports that have been published. Also take a look at the Zembla programme about the Living Lab.

The idea of global governance and trust in international institutions are apparently getting into deep water. But is there a legitimacy crisis? Not according to international élites, as Jan Aart Scholte (Leiden University), Soetkin Verhaegen (Maastricht University) and Jonas Tallberg (Stockholm University)…

Since 2006, HJD has made an important contribution to shaping diplomatic studies as an international academic field. Our new HJD Diplomacy Reading List presents a diverse collection of analyses categorized into forty-five topics published in HJD over the years. We hope these lists prove a valuable resource…

Marc Koper’s research focuses on electrocatalysis and electrochemical surface science for sustainable energy and chemistry. Reactions of interest are the redox reactions of the oxygen/hydrogen cycle (water oxidation, hydrogen evolution), the carbon cycle (reduction of carbon dioxide, oxidation of small…

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

Cardiovascular diseases (CVDs) are the leading global cause of mortality. Endothelial dysfunction, an early reversible stage of CVD development, is marked by decreased nitric oxide production linked to Ca2+ influx in endothelial cells.

Generations of Leiden students and academics have done archaeological research into the early medieval history of Oegstgeest. This makes this old settlement one of the best-documented sites from that era. In a new book, Leiden researchers take stock.

The effectiveness of the skin barrier underlies the outer layer of the skin: the stratum corneum (SC). However, in several skin diseases this barrier is impaired.
