Abstract

original image

Effizienz und Steuerungsfähigkeit sonochemischer Reaktionen steigert der Einsatz von Siliciumoberflächen mit Vertiefungen, in die Gas in einer Weise eingebracht werden kann, dass es auf Ultraschallbehandlung hin als Mikroblasenstrom freigesetzt wird (siehe Bilder). Um die chemisch aktiven Mikroblasen zu erhalten, sind weit geringere Ultraschallintensitäten erforderlich als in entsprechenden üblichen Reaktoren.
