Outline of Final Research Achievements

For a liquid-liquid phase process, uniformly sized water droplets were stably produced by a micro channel, and two produced small droplets were continuously merged in the channel. For a gas-liquid phase process, water droplets injected by two inkjet apparatus were impinged and merged continuously and stably in air. It was confirmed that the mixing rate of components in a merged droplets was much more rapid comparing to conventional homogeneous liquid mixing. The developed method was applied to nano-particle synthesis which requires rapid and uniform mixing. As the results, uniformly sized particles of Pt (1.4 nm) and RhPd (2.7 nm) were successfully produced.
