An acoustically actuated droplet apparatus includes a first sound source, a second sound source, a thread, two fixed columns and at least one droplet transporter. The first sound source includes a first emitting surface. The second sound source includes a second emitting surface, wherein the second emitting surface and the first emitting surface are arranged opposite to each other. The thread is coaxially passed through and placed between the first sound source and the second sound source, wherein the thread is hydrophobic. The two fixed columns are connected to two ends of the thread, wherein the first sound source and the second sound source are placed between the two fixed columns. The droplet transporter includes a tubing, a droplet dispenser and a solution container, wherein the droplet dispenser is connected with the solution container by the tubing, and the droplet dispenser is placed near the thread.

A sonic reactor for transferring kinetic energy to a process fluid medium has a resonant element horizontally oriented and mounted to the two resonance units using two or more nodal support rings located at the nodal positions of the resonant element. The nodal support rings are adjustable in position relative to the resonant element and the resonance units to permit positioning of the rings directly at the nodal positions during operation. The sonic reactor has a grinding or mixing chamber mounted at one or both of the free ends of the resonant element. The sonic reactor is used for applications that include fly ash beneficiation, pulverization and dispersion; fine ore grinding; preparing ready mix cement formulations; oil sands cuttings for oil recovery; spilled oil, water and oily water storage treatment; organic and inorganic industrial wastewater treatment; environmental remediation of contaminated soils; sodium dispersion and destruction of PCBs; biosludge conditioning; cellulosic biofuels processing; lignin processing; dispersion and deagglomeration of pigments; and dye destruction.

A method of generating bubbles of a first fluid in a second fluid, the method comprising: flowing a stream of the second fluid through a microfluidic channel; injecting a stream of the first fluid into the microfluidic channel through an aperture such that bubbles of the first fluid form in the second fluid; and sonicating the microfluidic channel with ultrasound so as to cause the bubbles formed at the aperture to divide.
