Abstract

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.
