Summary

Traduzione automatica

Dit protocol presenteert het gebruik van een gestopte stroommonsteromgeving om snel meerdere vloeibare oplossingen in situ te mengen tijdens een neutronenverstrooiingsmeting met een kleine hoek en om kinetische processen te bestuderen op nanometerlengteschalen en tweede tijdschalen.
