| Outline of Final Research Achievements |
Interfacial nanobubble is very thin vapor phase that exists at solid-liquid interface, was investigated using an atomic force microscope. Nanobubbles at the solid-liquid interface might contribute to the boiling initial bubble formation, however, often have questions such as in its stability. In this study, generation of nanobubbles is not determined only by the hydrophobicity of the surface, it was found that the presence of hydrophilic domains on the hydrophobic surface are affecting the nanobubbles. These results indicated that a possibility to control the nanobubbles by hydrophobic-hydrophilic combination surface.
