  • Microplasma discharge in deionized water and artificial seawater 

    Akimitsu Hatta, Vladislav Gamaleev, Jun-Seok Oh, Hiroshi Furuta

    International Journal of Plasma Environmental Science and Technology  13 ( 1 ) 1 - 6 2019.12  [Refereed]

     View Summary

    Microplasma discharges in deionized water and artificial seawater were investigated using pin-to-plate electrodes with a gap of a several tens of microns. By using a pulse voltage source, microdischarge was operated in deionized water and diluted artificial seawater and compared with discharge in ambient air. To operate the microdischarge in undiluted artificial seawater, a pulse current source (impulse generator) was used to supply the breakdown voltage with sufficient current. Even in seawater with an electrical conductivity of 45 mS/cm, microplasma discharges were reproducibly ignited at applied voltages below 1 kV. In the optical emission spectrum for the microplasma in artificial seawater, the main components of Na, Mg, Ca, K, S, H, and O were observed as distinguishable isolated lines, including lines for Pd, Ag and Fe from the electrodes.

  • Development of an Ambient Air Flow Rotating Arc Jet for Low-Temperature Treatment

    V. Gamaleev, N. Iwata, J.-S. Oh, M. Hiramatsu, M. Ito

    IEEE Access  7   93100 - 93107 2019.07  [Refereed]

     View Summary

    For low-temperature atmospheric pressure plasma treatment applications, we developed a novel rotating arc jet operated using various gases, including ambient air. We demonstrate the operation of plasma via the injection of various gas mixtures and tune operation parameters to achieve a low-temperature gas output from the arc jet. The rotating arc jet has an efficiency two orders of magnitude higher in the generation of reactive oxygen and nitrogen species than commercially available conventional nonequilibrium atmospheric pressure plasma jets operated with He or Ar gases. The high concentration of reactive species and use of ambient air as a process gas is promising for biomedical and agriculture applications. This work is a step toward the commercial use of plasma jets operated with ambient air.
