| Outline of Final Research Achievements |
A gas/liquid mixed medium is flowed through a micro flow channels fabricated by a 3D printer and a pulse voltage is applied to realize a system in which a large number of microplasma are in contact with liquid. This system can be applied to nanoparticle synthesis, decomposition of organic contaminants in water, hydrogen peroxide synthesis. It has been also shown that process control is possible by designing the flow channel structure. In addition, by using a ultra-thin micro reaction field directly beneath the liquid surface where the direct effects of plasma can reach, thin films with embedded nanoparticles have been fabricated. It has been also shown that size-regurated high density nanoparticles are formed in the films. Furthermore, it has been confirmed that the atmospheric plasma bullets propagate through the micro flow channels. This technology can be applied to the hydrophilic treatment of bone regeneration scaffolds.
