摘要
Sonochemistry at surfaces can be controlled by suitable surface patterning. Bubble nucleation occurs predominantly on hydrophobic surfaces (see picture, left), which thus can be selectively treated by ultrasound. The right-hand picture shows a structurally modified aluminum plate after ultrasound treatment. The inner circular region is hydrophobic, and the outer region is hydrophobic. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA.
