These works are based on the investigation only on each species or charged particle at the interface of a plasma-liquid couple .

The change of tStudy on the transfer and interaction of charged particles using ac glow discharge on liquids toward noble nanoparticle synthesis

The process was monitored via the measureStudy on the transfer and interaction of charged particles using AC glow discharge on liquids toward noble nanoparticle synthesisTHAI VAN PHUOCA thesi Study on the transfer and interaction of charged particles using ac glow discharge on liquids toward noble nanoparticle synthesis utions of nitrate salt. The results indicated that AC glow discharge alternately generates both positive ions and free electrons. The interaction of positive ions from AC glow discharge with water molecules leads to the generation of OH radicals and hydronimn cation FYee electrons from AC glow disch Study on the transfer and interaction of charged particles using ac glow discharge on liquids toward noble nanoparticle synthesis arge transfer and absorb into the liquid to form solvated electrons.The ability in the nano-synthesis of AC glow discharge was also investigated.

At a low pH level, solvated electrons arc captured by the available of H;|O* instead of reacting with metallic ions, and hence results in a small t he size of gold nanoparticles. At a high pH level, there is the Study on the transfer and interaction of charged particles using ac glow discharge on liquids toward noble nanoparticle synthesis change in the form of gold ions and therefore leads to a decrease in the redox potential of t he reaction Caq and gold ions.rhe synthesis of platinumStudy on the transfer and interaction of charged particles using ac glow discharge on liquids toward noble nanoparticle synthesis

In contrast, OH radicals oxidize copper ions and plat inum ions back to a higher oxidized value. The role of redox potent ial E° in the synthesis of noble nanoparticles was also clarified. At low redox potential, the reaction of Caq and metal ions occurs at a l Study on the transfer and interaction of charged particles using ac glow discharge on liquids toward noble nanoparticle synthesis ow equilibrium constant. The concentration of neutral atoms generated hence is not enough to reach a supersaturation for the nucleation process.
