安倍紘平（博士後期）と稲澤晋准教授は、混ざり合わない水と油の液体同士の境目(界面)を固体粒子で被覆すると、水に溶けているイオン濃度の大小に応じて界面の硬さが大きく変わることを突き止めました。この成果により、水中の油滴を安定に保つ技術開発や、その逆に油滴同士の合一(*)を促し好ましくない油を水中から効率的に分離・回収する技術開発につながることが期待されます。
Kohei Abe (Ph.D., second semester) and Associate Professor Susumu Inazawa have found that when the interface between liquids of water and oil, which do not mix, is coated with solid particles, the hardness of the interface changes significantly depending on the concentration of ions dissolved in the water. This achievement is expected to lead to the development of technology to keep oil droplets in water stable, and conversely, to the development of technology to efficiently separate and collect undesirable oil from water by promoting the coalescence of oil droplets.
