| Outline of Final Research Achievements |
Dissolution rate of a microbubble is large due to Laplace pressure. A novel crystallization technique has been proposed using fast gas dissolution from a microbubble. It is necessary to know the dissolution rate of a single microbubble and concentration distribution around a bubble for a process design. In this study, we developed a prediction model of dissolution rate for a microbubble coated by surfactant in a stationary liquid.

| Academic Significance and Societal Importance of the Research Achievements |
マイクロバブル溶解を利用した晶析は、気泡周囲に形成される高溶存気体濃度領域を利用するため、希薄溶液からの結晶製造が可能、また結晶個数の制御が可能になると期待され、医薬品など高付加価値な製品の製造に有用であると考えられる。本研究では、種々の界面活性剤が吸着したマイクロバブルの溶解速度を予測可能にしたため、化学産業や医療分野における様々な物質の高効率な製造プロセス設計に利用できると期待される。
