Anti-solvent crystallization of glycine was conducted under a standing-wave field given by 5.0 MHz
ultrasound. Columnar crystals of Glycine were fixed at each three dimensional lattice points with directing their
longer axis horizontally. The crystals were vibrating around the lattice points. Ultrasound helped to pin and to
orient the crystal at lattice points within liquids. Crystals located in the lattice points grow with irradiation time.
However, the size uniformity was less enhanced unlike our previous study under the irradiation of 1.6 MHz
ultrasound coupled with a mechanical stirring. The result shows that the unique behavior of glycine crystals
under a standing wave field brought about less uniform crystal growth. While, the characteristics of crystal
orientation helped to grow uniquely-shaped crystal. Multiple columnar crystals stuck together at their sidewalls.
