Measurement and Modeling of Atmospheric Pressure Nonthermal Plasma:
Atmospheric pressure nonthermal plasma has many applications such as decomposition of environmental pollutants, sterilization, air purification, surface treatment of materials, and plasma-assisted ignition/combustion. Although application of this plasma has been intensively studied, fundamental research (e.g., reaction processes) is incomplete. Against this background, we investigate the reaction processes of atmospheric pressure nonthermal plasma by measuring radicals such as OH, O, N, and O3 using laser diagnostic techniques (Refs. 1 & 2). In addition, we also analyze the reaction mechanisms using a numerical simulation in order to construct a plasma reaction model.
Applications of Atmospheric Pressure Nonthermal Plasma:
We develop a decomposition system for environmental pollutants using atmospheric pressure nonthermal plasma (Ref. 3). Being different from low pressure plasma, which is widely used for industrial applications such as the production of semiconductor devices, atmospheric pressure nonthermal plasma can be handled easily because it does not require vacuum devices, only air flow. Therefore, it is expected to have many applications and is currently being investigated by many researchers.

Spark Ignition of Hydrogen and Other Flammable Gases:
The study on the spark ignition of flammable gases has long relation to the electrostatic and spark ignition of internal combustion engines. However, the reaction in the spark ignition process has not been sufficiently measured, and, as a result, the spark ignition process is not fully understood. We focus on the spark ignition of hydrogen, which is used for fuel cells and is a hopeful candidate for next generation energy technologies. We investigate the characteristics of hydrogen spark ignition and elucidate the spark ignition process of hydrogen using laser diagnostic techniques. The electrostatic ignition of hydrogen should be assessed for developing hydrogen-based energy systems because hydrogen is easily ignited by electrostatic discharge due to its high reactivity.

| Future Plan |
The keywords for our researches include "plasma", "environement", "energy", and "safety". Our target is not fully ionized plasma used for nuclear fusion, but weakly ionized plasma used for many industrial applications, with a large potential for basic and applied research. We are also proceeding with research on the utilization and safety of next generation energy sources represented by hydrogen for fuel cells.

| Messages to Students |
Your research may sometimes go well and sometimes go wrong. You should proceed your research by trial and error. You should not be afraid of making mistakes in your research and have confidence in achieving your research aims. It is important to obtain such abilities during your time in the graduate school.
