The effects of ultrasound on micromixing
Ultrasonics Sonochemistry, 2016 The Villermaux-Dushman reaction is a widely used technique to study micromixing efficiencies with and without sonication. This paper shows that ultrasound can interfere with this reaction by sonolysis of potassium iodide, which is excessively available in the Villermaux-Dushman solution, into triiodide ions.
