The dissertation describes TEM experiments on heterogeneous catalysts.

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

Heterogeneous catalysis is essential to many industrial applications. These catalysts are often comprised of supported nanoparticles, which contain various different surface sites.

Molecular complexes can be used as electrocatalysts for oxygen reduction, water oxidation, and/or hydrogen peroxide production.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

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

Marc Koper heeft de Netherlands Catalysis and Chemistry Award ontvangen tijdens de 20e bijeenkomst van de Netherlands' Catalysis and Chemistry Conference. ‘De ultieme kandidaat voor deze prijs’, zo valt te lezen in een van de aanbevelingsbrieven.

Consequences for sediment stability and seston trapping

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

This thesis focuses on the synthesis, characterization and performance towards CO2 electroreduction of mono and bi-metallic particles based on p-block metals

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

To design the ideal water oxidation catalyst, understanding of the catalytic mechanism and decomposition pathways is essential.

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Organic molecules in interstellar space are important as they influence the structure of galaxies and star formations. Studying catalytic processes in space allows us to understand how molecular species are formed and chemically evolved in the interstellar medium and solar system objects.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

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

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.

Chemicus Irene Groot krijgt een TA-subsidie toegekend. Groot gaat samenwerken met Shell, Leiden Probe Microscopy, DSM Resolve en Universiteit Utrecht en onderzoek doen naar katalysatoren voor de productie van grondstoffen en brandstoffen.

Bicarbonate buffer is largely found in nature due to its ability to regulate pH variations around neutral values. As the pH changes, so does the speciation of the buffer.

Systems with local constraints is a new finding in recent researches on complex systems. The heterogeneous spatial interactions and the temporal dependencies among those numerous units make it difficult to describe by traditional statistical physics.

Bacteria are highly complex and diverse organisms that have adapted to survive in ecological niches ranging from the most extreme to the most heterogeneous environments.

Met de NMR faciliteit doen we onderzoek naar de synthese van paramagnetische moleculen om kennis te vergaren over de structuur en dynamiek van eiwitten. Deze kennis kan dienen als basis voor een medicijn dat zich hecht aan een eiwit of voor de ontwikkeling van vaccins. Medicijnontwikkeling is één van…

The filamentous bacteria Streptomyces are widespread inhabitants of terrestrial soils.

The main aim of this thesis was to unravel the signaling and regulatory networks that drive tumor cell migration during breast cancer metastasis.

Natural history collections provide invaluable sources for researchers with different disciplinary backgrounds, aspiring to study the geographical distribution of flora and fauna across the globe as well as other evolutionary processes.

Triple-negative breast cancer (TNBC) constitutes a small subtype (~15%) of breast cancer, but causes the majority of breast cancer-related deaths.
