Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

Greenhouse gasses in the atmosphere and fertilizers in the groundwater have negative consequences for our environment. With an electrochemical process they can be transformed to more valuable and useful substances like fuel and alcohol. Chemistry PhD candidate Elena Perez Gallent discovered how this…

Research of the Leiden Institute of Chemistry into the development of a sustainable fuel cell has accidentally resulted in an exceptionally efficient catalyst for the production of hydrogen peroxide. The catalyst, discovered by Dennis Hetterscheid and PhD candidate Michiel Langerman, may lead to a more…

The Dick Stufkens Prize 2019 for the best PhD thesis of the Holland Research School of Molecular Chemistry (HRSMC) will be awarded to Thom Hersbach. In his thesis, Hersbach presents a thorough analysis of cathodic corrosion. His comprehensive research, on which he graduated with the distinction cum…

Many researchers of the Faculty of Science are members of a research school related to their area of expertise. Research schools aim at collaboration of researchers from different faculties in the same university (interfaculty schools) or in different universities (interuniversity schools).

Lecture

Using a clever experiment, PhD candidate Shengxiang Yang discovered how gold electrodes convert water into oxygen. He is the first to unravel the mechanism of this reaction. Yang published his results in the journal ACS Catalysis.

Those pesky raindrops that get you wet on your way to work, are formed high up in the sky from clouds of water vapour. The process of nucleation describes the way this happens. Edgar Blokhuis of the Leiden Institute of Chemistry developed a theory to describe this transition more precisely. Chemists…

A full overview of THEOR PhD theses.

Electrocatalysis will play an increasingly important role in future in the transition to more sustainable energy. Thanks to chemist Isis Ledezma Yanez, we now know more about the hydrogen evolution process. PhD defence on the 9th of June.

Research at the THEOR group is comprised of the following research themes:

The research described in this thesis focused on the preparation of S/N functionalized carbene ligands and their transition metal complexes, and the exploration of their application as electrocatalysts for proton reduction.

In this thesis, the researcher developed a nanosystem based on the metallophilic Interaction between cyclometalated complexes.

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.

Platinum is a widely used catalyst, but its precise mechanism largely remains a mystery to scientists. Ludo Juurlink has now demonstrated for the first time how oxygen reacts on the platinum surface. Together with PhD students Kun Cao and Richard van Lent and international colleagues he publishes his…

A remarkable population of short period transiting rocky exoplanets with equilibrium temperatures on the order of 2,000 K has recently been discovered.

A common assumption in chemistry is that the coordination number of a catalyst's surface determines the reactivity of the reaction it catalyses. Strikingly, Leiden chemists have now proven that this is not true for nature’s most simple chemical reaction: the dissociation of hydrogen. The researchers…

It may well be possible to remove nitrate from polluted groundwater and at the same time produce ammonia in a sustainable way, according to PhD candidate Phebe van Langevelde and Professor Marc Koper of the Leiden Institute of Chemistry in Joule on 26 January. Together with a German colleague, they…

While colloidal aggregates are often undesirable due to their random shapes, we exploit them as a starting point to synthesize patchy particles.

Research at the MCBIM group is comprised of the following research themes:

The 21st century is witnessing a revolution in our understanding of rational points on surfaces and higher-dimensional varieties, and it is in this field that this project lies.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

We review the state-of-the-art in the theory of dissociative chemisorption (DC) of small gas phase molecules on metal surfaces, which is important to modeling heterogeneous catalysis for practical reasons, and for achieving an understanding of the wealth of experimental information that exists for this…

The research presented in this thesis explores the chemotherapeutic potential of metal-based compounds as chemotherapy agents, with an initial focus on the synthesis and DNA interaction studies of platinum and palladium compounds utilizing the [Pt(bapbpy)]2+ scaffold. The study identifies intercalation…

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

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…
