From atoms to the cosmos: exploring the cosmic web beyond collisional ionisation equilibrium
Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

More is alive: emergent multi-scale order & collective flows in tissues
The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

A computational study of structural and excitonic properties of chlorosomes
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…

Giant galactic outflows and shocks in the Cosmic Web
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-…

Withstanding the cold: energy feedback in simulations of galaxies that include a cold interstellar medium
Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

Platinum surface instabilities and their impact in electrochemistry
Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

Sander Nieuwenhuis over hoe onzekerheid werkt in de hersenen
Ons brein is een bron van onzekerheid, en we doen er alles aan om die te vermijden of te minimaliseren, aldus hoogleraar Sander Nieuwenhuis. Onzekerheid komt in allerlei vormen voor: van twijfels over wel of niet handelen tot sociale onzekerheid. Maar hoe verwerkt het brein die onzekerheid eigenlijk?…

Kunst bewijst het: christenen en moslims werkten samen in middeleeuws Irak
De relatie tussen christenen en moslims in het Midden-Oosten in de middeleeuwen wordt vaak getypeerd met termen als ‘conflict’ en ‘onderling geweld’. In zijn proefschrift zet Bas Snelders vraagtekens bij dat beeld. Analyse van kunst uit die periode laat namelijk zien dat beide gemeenschappen niet naast,…
