| Outline of Final Research Achievements |
This study aims to confirm that nanobubbles (NBs) have sufficient lifetime, and to reveal the factors that prolong the life NB and the physical properties measurement of solute of the surrounding. In 2014 FY, the effects of the additive (NaCl) to the lifetime of the oxygen NB were evaluated by electron microscope observation using the freeze fracture replica method. Results indicated that the number of NB decreased and their diameters increased depending on the storage period of the solution. A thin layer was observed on stored NBs. These results suggested that a small amount of NaCl tended to concentrate around the bubble, which might stabilize the bubble.
