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…

The probability for dissociation of molecules on metal surfaces, which often controls the rate of industrially important catalytic processes, can depend strongly on how energy is partitioned in the incident molecule. There are many example systems where the addition of vibrational energy promotes reaction…

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

An accurate description of reactive scattering of molecules on metal surfaces often requires the modeling of energy transfer between the molecule and the surface phonons. Although ab initio molecular dynamics (AIMD) can describe this energy transfer, AIMD is at present untractable for reactions with…

Four Leiden researchers have each been awarded a consolidator grant of up to 2 million euros by the European Research Council (ERC). They carry out research on a diverse range of subjects, from gender stereotyping in the field of science to making sugar molecules.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

The Leiden Institute of Chemistry (LIC) offers a unique tailor-made programme in Chemistry.

The Leiden Institute of Chemistry organises and participates in several programmes for high school students and teachers.

Synthetic hydrogels that mimic the natural extracellular matrix in the biophysical and biochemical cues it provides to cells are in high demand, however the cell phenotypes as they are observed in vivo in numerous cases have yet to be attained.

At Leiden Observatory, researchers investigate the origin of stars and their planetary systems. They detect and characterize planets around other stars (exoplanets). They study how stars and planets form. And they follow molecules from interstellar clouds to nascent planet systems. This way they address…

Coordination chemistry is the chemistry of metal atoms

The master’s specialisation Bio-Pharmaceutical Sciences and Education at Leiden University combines fundamental chemistry research with an excellent education in becoming a Chemistry teacher.

On the 19th of May 2020, our dear colleague and friend Professor Dr. Huib Ovaa has passed away from prostate cancer. Last summer Huib became ill, and in first instance it appeared that he had attracted a relatively harmless infectious disease. Unfortunately, it became soon apparent that he suffered…

In this thesis we have discussed several parameters that affect the electrochemical conversion of enviromentaly harmful molecules such as nitrates and carbon dioxide to more valuable and less deleterious compounds, in order to cast light onto the mechanism of the reaction to achieve an efficient and…

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

A new type of tripodal squaramide-based supramolecular hydrogels is developed and studied.

This doctoral thesis is an effort to understand how lipid phase-separation induced by diacylglycerol analogues in lipid-based nanoparticles affects their in vivo behavior, leading to specific nanoparticle-protein communications and selective cell targeting.

The main goal of this thesis is to achieve advanced control of binding properties in bis-pyrrolic and macrocyclic pyrrolic receptors by light.

A structural investigation of coiled coil peptides used as membrane fusogens, mimicing naturally occuring coiled-coil fusion proteins. Synthetic modifications have been made to alter lipid attachment, secondary structure and to insert photoactive azobenzene moieties for active control over coiled coil…

The goal of this thesis is to understand how interfacial parameters, such as the addition of organic additives, bulk pH or metal cations of the electrolyte, affect the relevant electrocatalytic reactions, i.e. electrochemical CO2 reduction reaction or hydrogen evolution reaction.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

Methods for accurately computing the interaction of molecules with metal surfaces are critical to understanding and thereby improving heterogeneous catalysis.
