The research aim of the Catalysis and Surface Chemistry group headed by Prof. Marc Koper is to probe and understand chemical reactions on well-defined, mostly single crystalline, surfaces at the molecular level.

Curved single crystals provide variable, but well-defined surface structures.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

The local ordering of atoms at the surface of a metallic particle determines its catalytic activity and selectivity. As energy systems of the future will be based on efficient catalytic conversion of small molecules in closed cycles, we study how structural effects of catalysts can be used to our ad…

In this thesis integral points on affine del Pezzo surfaces are studied.

As a student in the MSc Chemistry programme offered by the Leiden Institute of Chemistry (LIC) you will focus your studies on one of the two main research areas of the LIC. Students in the research area Chemical Biology will study fundamental biological and biomedical problems to understand physiological…

Surface plasmons (SPs) are surface waves at the interface between a dielectric and a good metal, and are formed by the interaction between light and the free electrons at the metal-dielectric interface. They provide strong field confinement for optical fields, opening new possibilities for enhanced…

Several techniques are explored for going beyond the born-oppenheimer static surface model for molecule-surface reactions.

Theorists have recently made substantial progress in simulating reactive molecule-metal surface scattering but still face major challenges. The grand challenge is to develop an approach that enables accurate predictive calculations of reactions involving electronically excited states with potential…

Is it possible to successfully design self-assembling nano-scale protein skeletons for use as a vaccine platform?

The surface and the edges of graphene are expected to provide higher sensitivity and specificity in detecting and characterizing single molecules. However fundamental physical limits exist in reaching an ultimate precision in detecting the dynamics of chemical and biological systems. The research in…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

The Leiden Institute of Chemistry actively participates in several national research schools for MSc and PhD students. These schools are consortia that stimulate collaboration between research groups of the different participating Dutch universities. The research schools also offer advanced training…

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

The Supramolecular & Biomaterials Chemistry group comprises the PIs Alexander Kros, Roxanne Kieltyka, Gregory Schneider and Sander Wezenberg, and is active in the field of self-assembly of amphiphilic peptides and applying them in supramolecular chemistry.

This research focuses on the (Quantum) Dynamics (QD) of the reactive scattering of H2 from metal surfaces.

Research within our group revolves around the atomic structures of large bio-molecules and their complexes.

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 research presented in this thesis makes use of small molecules (as H2 , D2 and O2 ) on well-defined single crystal surfaces (flat Pt(111), flat Cu(211) and curved Pt(111)) to elucidate the role of surface structure and degrees of freedom in the reactant in specific surface reactions.
