Research Abstract

Plasma generated in gas bubbles enabled efficient decomposition of harmful substances in water. By adding a pressure pulsation on the feeding gas flow, a synchronized formation of the plasma and the bubbles has been successfully demonstrated. The synchronization enabled not only to control the plasma-chemical reactions at the gas-liquid interface but also to generate a multiple generation of the plasma in gas bubbles.
