摘要：

(Figure presented) Acoustically agitated suspensions of particles fired at an electrode placed directly opposite the ultrasonic horn have been explored. The authors demonstrate the potential analytical power of the technique for the determination of the number and size of particles in solution. The diagram illustrates the probable mechanism for the process occurring at the electrode and the effect on the measured current as a function of time. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
