Outline of Final Research Achievements

Antisolvent crystallization of glycine was conducted under a standing-wave field created by irradiating high frequency ultrasound. With the help of acoustic pressure working on glycine particles, they located highly regularly in the liquid with an interval corresponds to a single wave length. Particles were oriented to direct the longer axis horizontally. Particles glowed with the progress of time under a given ultrasonic power. The size distribution also changed with a transient of time. Therefore, particle size is controlled by choosing an appropriate time for the irradiation. Crystallization behavior of glycine was quite different under a different aspect of wave-field in which acoustic streaming is prevailing. Under the acoustic streaming, no particle orientation and regular locating was obtained. There was no change in particle size with time, and the size was similar to the value obtained at initial stage for the case of standing wave-field.
