Abstract：
Plasma in gas phase is widely used in many industrial fields such as electronic device manufacturing processes (plasma etching, sputtering, plasma-enhanced CVD, etc.), hard coating processes (ion plating, sputtering, etc.), surface treatment processes (low or atmospheric pressure plasma treatments, sputtering, plasma etching, etc.) and so on. Plasma in liquid phase is not generally well-known, although it has been partially utilized in water treatments and electrical discharge machining. In particular, the fundamentals of non-equilibrium plasma in liquid phase have not been established, including its generation techniques, its state, and activated chemical species. Actually, it can realize a higher reaction rate under lower-temperature conditions, and a greater chemical reaction variability since the molecular density of liquid is higher than that of gas phase. A specific type of non-equilibrium plasma in liquid phase was named as “solution plasma”. By using solution plasma process (SPP), we can introduce variety of plasma by choosing the combinations of solvents and solutes in solutions. In this lecture, the fundamental characteristics of solution plasma process and its applications including syntheses of nanoparticles catalyst, nano-carbon materials such as graphitic structure carbon as cathode material for Li-air battery application, metallic and non-metal catalysts supported on carbon matrix for fuel cell application, and biocompatible gold nanoparticles from natural products. This lecture will give an overview of solution plasma process for a board range of material synthesis. 

CV：
Oi Lun Helena LI received her BASc (2004) in University of Toronto, Canada, MASc (2006) and PhD (2010) in McMaster University, Canada. From 2010 to 2012, she worked as a researcher at Nagoya University, Japan. In 2013, she joined the faculty of Green Mobility Collaborative Research Center at Nagoya University, Japan.
Oi Lun Helena’s research interests mainly focus on applying the technology of plasma discharge in liquid to the field of water treatment, biomass degradation and material synthesis. “Solution Plasma”, is named for the specific liquid-phase plasma with various combinations of solvents and solutes in solution. The high voltage electrical discharge occurs directly in water and initiates both chemical and physical processes. It has been demonstrated to produce UV, hydrogen peroxide, hydrogen, oxygen and other radicals and ions. She has carried out studies involved:
1. Disinfection and chemical degradation for water treatment
2. Biomass degradation to ethanol for energy conversion
3. Synthesis of size-controllable metal nanoparticle 
4. Synthesis of tunable-structure carbon
5. Synthesis of heteroatom-doped carbon for energy storage application
