Outline of Final Research Achievements

In this year, we have produced "nano-bubbles" using oxygen gas and attempted to fabricate the gold nanoparticles under the environment existing oxygen nano-bubbles. Furthermore, we have found that the adsorbed oxygen on the gold nanoparticles prepared by the solution plasma method was in the ionic state by HAXPES measurement in SPring-8. However, an information on more oxygen atoms adsorbed on the surface of gold nanoparticles fabricated with oxygen nano-bubbles could not be obtained. In the future, we plan to optimize the solution temperature and/or the bubble density.
