| Outline of Final Research Achievements |
In the production of crystalline chemical products, crystalline particles with the desired size and monodispersity are required. For this purpose, precise control of nucleation is essential. In this study, the template interface developed at the air-liquid interface was used. By resetting the interface by heating, the local supersaturation was successfully retained, and the number of nucleation could be controlled. Nucleation control is also important issue in multicomponent co-crystal production. As a result of the control of nucleation for co-crystals, the relationship between nucleation and crystal quality, such as the uniformity of crystalline particles, was also clarified.

| Academic Significance and Societal Importance of the Research Achievements |
結晶化プロセスの核化はその後の成長にも影響するため、より精密な制御が要求される。鋳型界面には、核化トリガーの機能が備わっており、その機能を充分に発揮できるような操作法を見いだすことが必要である。そこで、鋳型界面上に局所的に限定させた過飽和を実現させることで、核化数の制御に成功した。核化や核化数の制御は均一な品質を有した結晶粒子群製造に必須の技術であり、本研究の結果によって結晶化の推進力と核化制御による結晶粒子群の均一性との関係を整理できた。
