Sonochemistry for coatings
When ultrasonic waves collapse near a solid surface, microjets are being formed directed towards the solid surface. These microjets are moving at very high speeds. This phenomenon can be used for coatings nanoparticles on metals, polymers, glasses, ceramics, textiles, and paper. Prof. Aharon Gedanken of Bar-Ilan University, Israel, explains the mechanism of sonochemistry and comments on the benefits of this method.
