Significant contributions have been made by the Programme to acoustic cavitation studies of charged microbubbles imploding in fluids. The nonlinear, forced oscillations of a bubble in a fluid due to an external pressure field were studied theoretically. In the presence of a constant charge on the bubble, the bubble oscillator’s behaviour changes markedly. Ours are the first studies of pressure and charge thresholds worldwide and have enormous applications for medical diagnostics and damage control of industrial machinery in fluids.
