Proceedings of 1999 IEEE 13th International Conference on Dielectric Liquids (ICDL'99) (Cat. No.99CH36213), 1999

Moreover, electrical and transport parameters are mainly a function of fluid density N. For each density, above a threshold voltage Vk, the electric current I which is space charge limited is correlated to an intense light emission confined close to the tip needle. The spectral analysis of the emitted light can be used to evaluate some parameters of this non equilibrium weakly ionised region. For example, the kinetic temperature Tk in the corona region has been deduced from pressure broadening of several selected lines of argon

DBDP Reactor was constructed with spiral wire and cylinder. Plasma condition has been generated by using AC high voltage Ozone has been produced by this technology with oxygen and dry air as sources for ozone generating. In this research we found that the concentration of ozone produced increases with increasing voltage with a time constant. This concentration also increases with increasing time in certain applied voltage. Ozone concentration was higher than the concentration of dissolved ozone in water. Dissolved ozone in water was only 10 % of ozone produced and only 7 % for dry air as source. Oxygen as source of ozone was better than dry air; both for ozone produced and dissolved ozone in water.

Corona discharge was generated in two system electrodes such as: point to plane electrodes, and point to sphere electrodes. Plane and sphere electrodes have been made by liquid metal electrode (Mercury). Corona discharge has been generated by using direct current high voltage. The first aim of this research was to have a discharge glow plasma characteristic with point to plane electrode and the plane (or sphere) electrodes were liquid metal. The second aim was to observe an emission of corona glow discharge plasma. From this research, we found the crystal growth in plane (or sphere) electrode, and we consider that crystal growth observable fact as new phenomenon. The crystal growth has been found only for positive corona discharge and sign of growth follow the very intense electric field at the center point electrode. On the other hand, for negative corona discharge, crystal growth has not bee...

Distilled water on the order of microliters is dropped onto wounds before treatment. To assess the fate of the water, an infrared thermal imager is applied. To evaluate the healing effect, macroscopic and immunohistological studies are conducted. Regarding the wound contractile effect, we show that combination treatment of plasma with dropped water seemed to have a greater effect than plasma treatment alone. Plasma may modify the wound surface through such water, chemically and physically. The histological stiffness of the wound surface during maturation and remodeling, however, may also influence the fate of the water during treatment.
