| Outline of Final Research Achievements |
The purpose of this study is to clarify the fluid lubrication phenomenon of nano-sliding gaps by focusing on the flow of lubricant molecules. We have proposed a method for measuring the flow of lubricant molecules in a nano-gaps using a micro fluidic device, and have successfully confirmed the principle. In addition, we have succeeded in constructing a measurement system based on ellipsometry and confirming the principle of simultaneous measurement of shear force and gap for nano-gap lubrication.

ナノしゅう動すきまにおいては，流体潤滑作用の本質である潤滑剤分子の流れの解明は困難で，その理論体系確立の大きな障害となっていた．そして，潤滑剤分子の流れとしては，局所的な圧力差による圧力流れとしゅう動面のせん断によるせん断流れの解明が必須だが，いずれもナノすきまでの計測は困難だった．本研究では，新規な計測法の提案と実証に取り組み，その原理確認に成功した．
