Schwereloser Staub: Forscher entdecken überraschende Entmischung geladener Mikropartikel

(PresseBox) (Greifswald, )
Mikropartikel in Plasmen entmischen sich bereits bei allerkleinsten Ladungsunterschieden. Das konnten Physiker der Ernst-Moritz-Arndt-Universität Greifswald und der Christian-Albrechts-Universität zu Kiel (CAU) nun in einem Experiment unter Schwerelosigkeitsbedingungen demonstrieren. Das Verhalten staubhaltiger Plasmen interessiert nicht nur die Grundlagenforscher, sondern ist auch für immer mehr technologische Anwendungen von großer Bedeutung. Die Resultate wurden aktuell im renommierten Fachjournal Physical Review Letters (Phys. Rev. Lett. 116, 115002 – Published 14 March 2016) veröffentlicht.

Aus der Alltagserfahrung wissen wir, dass sich Wasser und Öl nicht vermischen. In ähnlicher Weise tendieren Systeme aus zwei Sorten geladener Partikel dann zur Entmischung, wenn der Ladungsunterschied zwischen beiden Sorten ygdg nwutajrrc Tmjyt zodnezaahggfr.
