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…

Psycho-physiological reactions to stress.

The following master research projects are currently open in the Bouwmeester group.

An estimated 17% of our university's total carbon footprint comes from the thousands of travel movements by our staff, students, visitors, and suppliers. Our aim is to reduce these emissions by a quarter in the coming years.

The main research theme in the group of Dennis Hetterscheid is to understand and mimic bioinorganic multi-electron processes that are relevant to our future energy infrastructure. Reduction of protons generates hydrogen that can be used as a chemical fuel. Alternatively to gaseous hydrogen, the reduction…

Lecture

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

The dissociative chemisorption of a molecule on a transition metal surface represents a rate-limiting step in many heterogeneously catalyzed processes, whereby most chemicals are made. In spite of the importance of this reaction, an accurate first principles approach to modeling it does not yet exist.…

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

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.

Crises like climate change and loss of biodiversity threaten our planet. That’s why sustainability is an important topic in research and education across Leiden University. On this website you read how scientists from many disciplines work together in researching sustainability.

Can the conditioning paradigm be used for checkpoint inhibition cancer treatment?

Three at the same time: a ligation strategy combining tetrazine–norbornene cycloaddition, Staudinger–Bertozzi ligation, and copper(I)-catalyzed click reaction was used to label the three catalytic activities of the proteasome simultaneously in a single experiment. The orthogonality of the three ligation…

In this article Fisher, Klein & Codjo introduce the FOCUSdate Project and they show how the sentiment data provide unique abilities to analyze Russia's and Iran's reactions to US policies and events and NGO human rights campaigns.

A full overview of THEOR PhD theses.

We report new computational and experimental evidence of an efficient and astrochemically relevant formation route to formaldehyde (H2CO). This simplest carbonylic compound is central to the formation of complex organics in cold interstellar clouds and is generally regarded to be formed by the hydrogenation…

Individual molecules are extremely hard to see through feeble fluorescence. Tiny gold nanorods serve as new antennas to intensify their signal 500 times. Publication on 24 February in Angewandte Chemie.

The sustainable production of hydrogen could potentially be made more efficient by adding a cleverly chosen salt to the process. Researchers at the Leiden Institute of Chemistry (LIC), in collaboration with physicists at the University of Twente, have discovered that the type of salt present in the…

The nanoscale structure of a catalyst under reaction conditions determines its activity, selectivity, and stability. For the production of sustainable energy and materials, new catalysts are needed. By understanding the structure-activity relationships of catalysts under reaction conditions, insight…

Central in coordination and organometallic chemistry is the synthesis of new chelating ligands, the synthesis and characterization of metal complexes with these ligands, and the study of their properties. An important goal in my research is to create understanding of the relation between the structures…

Although sexual abstinence before marriage is no longer the central message in The Netherlands the affective relationship as a criterion for professionals within criminal justice can be seen as a more contemporary version of marriage.

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.

Climate change and energy transition were an important theme of the Dutch provincial elections: how should we invest in new sources of energy? Leiden University conducts multidisciplinary research into renewable energy solutions. Read more about this in the ‘Renewable Energy’ research dossier.

Vast, often populated, areas in dryland ecosystems face the dangers of desertification.

Leiden University is a integral part of the community and contributes to a sustainable society. Over the coming years our University will become even greener.

The Leiden University Green Office has some great news: you can now make the most environmentally-friendly search engine - Ecosia - your default on a public LU computer!

The world we live in is changing in many aspects at an ever-increasing speed. And it will continue to do so. How do we anticipate these changes, such as the increase in atmospheric CO2, the extinction of species and industrialisation?

This guide relays information on tips and tricks for traveling by train and bus, and which online tools you can use for sustainable travel and trip planning.

The central theme of Rik Mom’s research group is to identify what the electrode-electrolyte interface looks like when electrocatalysis is taking place. Using specialized forms of Raman and X-ray spectroscopy, we study the chemical state and bonding environment of the electrode surface and near-surface…

Atherosclerosis (thickening of the artery wall) is the most common cause of heart attacks or strokes, and one of the most common causes of death in the western world. People with this condition have to take medicine all their lives, so a vaccine for atherosclerosis would be a breakthrough.

All living creatures have to cope with environmental demands and threats that challenge their physical or emotional homeostasis.
