Laboratory for Astrophysics
We simuleren interstellaire wolken met speciale plasma-expansies en chemische reacties op ijzige stofdeeltjes in ultrahoogvacuümopstellingen. Dit levert gegevens die nodig zijn om astronomische waarnemingen te interpreteren en de reactienetwerken in de ruimte te modelleren.

Computational and experimental studies of reactive intermediates in glycosylation reactions
Carbohydrates, or sugars, are the most diverse and most abundant biomolecules known. However, the isolation of carbohydrate samples in sufficient amounts and purity is often impractical or even impossible, so the chemical synthesis of glycosides becomes relevant. The glycosylation reaction, in which…

Transformation and sublimation of interstellar ices: insights from laboratory experiments and astronomical observations
Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

The individual level effect of symbolic representation: An experimental study on teacher-student gender congruence and students’ perceived abilities
Onderzoek naar representatieve bureaucratie heeft vaak de positieve prestatie-effecten bevestigd van bureaucratieën die de demografische kenmerken van hun cliënten weerspiegelen. Er is echter weinig bekend over de onderliggende mechanismen op individueel niveau die tot deze resultaten leiden.

Ingredients of the planet-formation puzzle
High-angular-resolution observations of the circumstellar material have uncovered numerous and very diverse substructures in protoplanetary discs, raising the question of whether they are caused by forming planets or other mechanisms.

Solution in Dissolution: dynamics and fate of metal-based nanoparticles in toxicity assessment
Dissolution processes – next to aggregation processes - play an important role for fate prediction and environmental risk assessment of metal-based nanoparticles (MNPs). It is challenging to predict the kinetics of the dissolution process of MNPs in complex systems such as we can find in in vivo and…
