The invention relates to a method which comprises emitting ultrasound into a liquid mixture containing first and second reagents in separate phases initially separated by a liquid precursor-gas barrier, the ultrasound having a high enough energy level to vaporize the precursor gas, such as to contact the reagents and thus to activate a chemical reaction therebetween.
