Chemical wave generation heterogeneous

The use of ultrasound to accelerate heterogeneous reactions is growing rapidly [22-25]. This technique has generated a field of study commonly labeled sonochemistry. Much of the rapid rise in popularity of sonochemistry stems from the fact that ultrasound can be delivered safely, conveniently, and with inexpensive equipment. Ultrasound can affect chemical reactions at a metal-solution interface when the sound waves induce cavitation or the rapid growth and sudden collapse of bubbles at the metal-solution interface.
