Contact Metals in Catalysis, Biomimetics & Inorganic Chemisrty

Photocatalysis has emerged as a powerful tool for enabling challenging transformations in organic synthesis. This thesis explores the development of several photocatalytic reactions designed to form carbon-heteroatom bonds from less-functionalized precursors.

Chemotherapy that does not harm the body, but effectively fights cancer cells: that is the goal of chemist Sylvestre Bonnet and his team. During his PhD research, chemist Xuequan Zhou brought that goal a little closer. He developed molecules that, upon injection in the bloodstream, self-assemble into…

LiTechAe: Percussive stone tools related to stone masonry techniques seen through experimentation and use-wear analysis.

‘A challenging rollercoaster, but also a very bonding and insightful experience,’ that’s how the team of iGEM Leiden 2022 wraps up their participation in the iGEM contest. The contest for synthetic biology climaxed during the Grand Jamboree in Paris. The team ended up in the top 10 of over 360 teams…

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.

In photoactivated chemotherapy (PACT), a biologically active compound is caged by a light-cleavable protecting group.

Cathodic corrosion for producing nanoparticles was (re)discovered when trying to control the electrochemical etching of a scanning tunneling microscopy (STM) tip.

Hydrogen peroxide (H2O2) generation via electrochemical oxygen reduction is a sustainable production method for this bulk chemical. However, the selectivity of molecular catalysts for electrochemical H2O2 generation has hardly been investigated in a systematic manner, and it is unknown if their stability…

Indonesia is experiencing various environmental challenges related to its fast economic growth. Therefore, it is necessary to have measurable and applicable indicators to obtain accurate data and information regarding the costs of adverse environmental impacts arising from economic activities to support…

The dissociative chemisorption of methane on metal surfaces is of fundamental and practical interest, being a rate-limiting step in the steam reforming process. The reaction is best modeled with quantum dynamics calculations, but these are currently not guaranteed to produce accurate results because…

Nonadiabatic energy transfer from the translational motion (T) of a molecule impinging on metal surface to the metal’s electrons may determine whether the molecule can lose enough energy to adsorb or react.

Elk jaar organiseert het LIBC in samenwerking met de gemeente Leiden een Publieksdag over hersenonderzoek.

The master’s degree programme Education and Child Studies is an academic, not a vocational programme. It offers research-based knowledge about education and child development.

Wordt het nog wat met de Arabische lente?

Along with your application, you will need to submit a variety of documents. This information only applies to students who need to submit an admission application. If you have a bachelor’s degree from Leiden University that grants you automatic admission to a master’s degree in the same field, you don’t…

Over the past century, the world population has grown exponentially, as has our need for energy and raw materials. If we wish to continue to live prosperously in the future, we have to radically restructure our economy and consumption. Scientific research shows us how to do this.

The van Exter group has an extensive history of prior research in classical and quantum optics. As former part of the group of Han Woerdman, we have studied topics as diverse as:

For hundreds of years, children in Ancient Egypt learned to read using The Satire of the Trades, a text in which a father gives advice to his son through descriptions of different professions. PhD candidate Judith Jurjens investigated how this worked in practice.

Chemical biology research at the Leiden Institute of Chemistry is aimed at understanding biological processes at the molecular level to strengthen the knowledge base of human health and disease. The approach to achieve this goal is a fundamental chemical one; with the aid of chemical probes biological…

The goal of the research presented in this thesis was to explore the chemical space of ruthenium(II) photocages, investigate their ability to host potent chemotherapy drugs, and to red shift the activation wavelength of the most promising PACT candidates to conduct biological studies.

The mechanism of the electrochemical reduction of dioxygen by a mononuclear pyridylalkylamine copper complex was investigated (see picture). It was shown that in neutral aqueous solution dioxygen undergoes stepwise reduction, wherein hydrogen peroxide plays a key role. The rate constants determined…

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.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

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

On the 12th of November, Xander Vertegaal successfully defended a doctoral thesis and graduated. The Leiden University Centre for Linguistics congratulates Xander on this achievement!

This thesis presents insights from our study of various correlated electron systems with a scanning tunneling microscope (STM). In ordinary metals, electron-electron interactions exist, but get substantially screened due to the sheer number of electrons.

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.

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.
