Carbon dioxide capture and utilization technologies are necessary to create a truly circular economy. The electrochemical reduction of carbon dioxide to formate is an appealing carbon utilization method as it can be performed at room temperature and pressure, it only requires two electrons, and it has…

The research group of Semonti Bhattacharyya at the Leiden Institute of Physics studies quantum transport measurements in Van der Waals heterostructures.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

Brownian motion is the random motion of (colloidal) particles due to collisions with the atoms and molecules of the solvents, which are moving due to temperature.

In most applications, electrocatalysts exhibit a large surface area to volume ratio, for example using nanoparticles.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

How do you fit two meters of DNA in a tiny compartment and at the same time are able to access the right parts of it at the right times?

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.

The radio sky harbours both galactic and extragalactic sources of arcminute- to degree-scale emission of various physical origins. To discover extragalactic diffuse emission in the Cosmic Web beyond galaxy clusters, one must image low–surface brightness structures amidst a sea of brighter compact fore-…

Research in the van Exter lab focuses on quantum aspects of light and light-matter interaction. One of our long-term goals is to develop a reliable quantum memory, based on a single emitter in an open micro cavity.

Tracing the evolution of the molecular gas content in galaxies is critical for a complete understanding of galaxy formation and evolution, as it provides the direct fuel for star formation. Studies of high-redshift (z>1) molecular gas reservoirs, most commonly traced by carbon monoxide (CO), have seen…

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

In the Catalysis and Surface Chemistry group, we investigate how catalysis works on the molecular level. The group is divided in six subgroups, focusing on different aspects of heterogeneous catalysis, homogeneous catalysis and electrocatalysis.

Nuclear Magnetic Resonance (NMR) Spectroscopy is a non-destructive analytical technique that is used to study the nature and characteristics of molecules with an atomic level precision. It has a wide range of applications especially in synthetic chemistry, biological and biochemical research groups…

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.

The Tatiana Afanassjewa-lecture series was a series of public talks in Dutch that was started during the Covid-19 lockdown. The talks were given by Leiden physicists on wednesday evenings, intended for everyone with an interest in physics.

Tineke Berkers has won an award for outstanding contribution for her poster at the Gordon Research Conference at Waterville Valley, USA.

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…

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.…

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…

Patients with skin diseases such as eczema and psoriasis, sometimes spend a lifetime searching for the right medication. To help these patients faster and better, scientists across the country are joining forces. The Next Generation ImmunoDermatology (NGID) project, with LACDR professor Robert Rissmann…

Every year, the Leiden Institute of Physics (LION) organises the Science Day. The goal is to highlight the newest research at LION, to socialise, and to welcome first year master students and new PhD candidates to our institute.

The symposium is open to all registered participants and consists of a two-day programme and a poster session.

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

This thesis describes the synthesis and biochemical evaluation of a variety of cyclophellitol based activity-based probes and inhibitors targeting various endo- and exo-acting retaining glycosidases. In the last two decades a variety of probes and inhibitors for (hemi)cellulose degrading enzymes have…

Advancing the understanding of the interaction of light and matter on the single-quantum level is important for near-future quantum technologies but also to answer fundamental questions.

How are the building blocks of life formed?

A recent collaborative paper between researchers from the Theoretical Chemistry & Catalysis and Surface Chemistry groups has been chosen by the renowned Physical Chemistry Chemical Physics journal as a

Studying surfaces of solid materials: it may not seem relevant to energy consumption, but it is. Marcel Rost studies how platinum electrodes wear out. Those electrodes are a crucial component in the fuel cells of hydrogen-powered cars. ‘We need to make the switch from fossil fuel energy to hydrogen.…

Smooth platinum electrodes roughen and wear when subjected to repeated cycles of oxidation and reduction, which causes nanometer-scale mounds to grow. Leiden chemists Leon Jacobse and Marc Koper, together with physicist Marcel Rost, discovered the exact details, using a unique tunneling microscope.

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…
