| Research Abstract |
Fine monomodal crystalline particles are required to manufacture in many fields. In this study, the effect of template at the air/solution interface on the nucleation phenomena was investigated. And the relationship between nucleation timing and the timing in which the template interfaces were given into the supersaturated solution became clear, and nucleation phenomenon of templated crystallization was also investigated. If the timing of nucleation can be controlled by using template effects, monomodal crystalline particles can also be produced. The glycine - water - L-leucine (template compound) system was used. As the results, the nucleation timing of which template interface was given into the supersaturated solution was important for controlling size distribution. The formation of new template interface into the supersaturated solution acted as the nucleation trigger which induced purposeful nucleation. By using this nucleation trigger, monomodal crystalline particles were obtained at the air/solution interface.
