Abstract
Ultrasound for use in promoting a chemical reaction is generated by an electromagnet formed from a pair of magnetostrictive prongs wound with coils that are oriented to produce an oscillating magnetostrictive force when an oscillating voltage is applied, in conjunction with a sensing electromagnet of magnetostrictive material that is arranged to receive the vibrations generated by the driving electromagnet and produce internal magnetic field changes due to the reverse magnetostrictive effect. These field changes generate voltages that are representative of the amplitude of the oscillating magnetostrictive force. The generated voltage is compared to a target value in a control circuit that adjusts the applied oscillating voltage accordingly. The oscillations in the prongs of the electromagnet are transmitted to an ultrasonic horn that is immersed in the reaction medium to provide direct contact with the reaction mixture.
