The long-held desire - to link structure directly to function and to explain molecular mechanisms based on basic chemical or physical principles - is finally coming closer, satisfying not only our scientific curiosity but also offering new solutions to the many challenges in the field of health, energy…

Despite the history of studies on methanol formation from CO2, the dominant elementary reaction steps that constitute the chemical mechanism for this catalyzed process are not determined.

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

Electoral Systems and Turnout: Evidence From a Regression Discontinuity Design. In dit artikel, gepubliceerd op de website SAGE research methods, bespreken auteurs Jaroslaw Kantorowicz en Tobias M. Hlobil hoe een Regression Discontinuity Design uitgevoerd kan worden.

Veel van de grote uitdagingen van de 21ste eeuw (klimaatverandering, internationale migratie, financiële instabiliteit, sociaal-economische ongelijkheid) vinden hun oorsprong in de organisatie van de wereldeconomie. Elke oplossing voor de grote uitdagingen van de wereld vereist daarom krachtige beleidsinterventies…

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

Het FAIRDOM-consortium is een open initiatief van verschillende partners, waaronder financieringsprogramma's, grote consortia, instituten, kleine groepen en individuen.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

Has the industrial sector in China effectively been decarbonizing in recent years, across different regions and subsectors, and is it plausible that it will reduce its CO2 emissions in conformity with national and internationally pledged emission goals?

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

What is the environmental impact of different waste collection systems across Europe? How can the collection be improved when considering collection, sorting, and treatment, as well as use options for secondary materials?

How are links between macro-invertebrate diversity and ecosystem functioning influenced by anthropogenic pressures?

Software development is a complex process. It is important that software products become stable and maintainable assets.

There is a need for alternative methods to replace, reduce and refine (3R) animal experimentation. Combining experimental data from high-throughput in vitro studies with in silico modeling is a promising approach to unravel the effect of chemicals on living cells and to gain a better understanding of…

Agrobacterium tumefaciens, a gram-negative plant pathogen belonging to the family Rhizobiaceae, is the causative agent of crown gall disease, which can affect many plant species including agronomically important ones.

This thesis aims to improve the detection from ultra-weak single emitter by enhancing their emission properties with plasmonic nanostructures. We exploit the wet-chemically synthesized single crystalline gold nanorods (GNRs) as our basic frameworks in the whole studies, simply because of their unique…
