• 水とフルオラス溶媒の液液界面の可能性
• 粗面および微粒子表面の吸着分子配向を解明する新しい拡散反射測定・解析法の開拓
• This motion-restricted water was further studied by the IR spectral ‘variation’ in detail with an aid of quantum calculation by changing the number of hydration water molecules. As a result, the newly found “third water” was revealed to have a H-bonded complex with a unique ring-shape on two sites of the SA group, which explains the motion restriction., 26810075共同研究・競争的資金等の研究課題
• 本研究では，粉末のような複雑な表面構造を持つ試料表面での光拡散であっても，本質的には捕集した光を正反射と拡散の2成分に分離するため，DRフィルターを初めて導入した。共同研究・競争的資金等の研究課題
