Investigating intensities of very high voltage rise dv/dt pulsed power source in atmospheric microplasma
Siti Khadijah, Za'aba, Dr.; Akitsu, Tetsuya; Otagawa, Tomohiro; Yamazaki, Shinsuke; Sakurai, Takeki (2007-06)Micro barrier discharge operating at atmospheric air was excited by a compact pulse generator which has the capability to produce fast rising voltage pulse with maximum rise up voltage as high as 435MV/s. Sequences of ... -
Plasma disinfection and the deterioration of surgical tools at atmospheric pressure plasma
Siti Khadijah, Zaaba; Akitsu, Tetsuya; Ohkawa, Hiroshi; Katayama-Hirayama, Keiko; Tsuji, Masao; Shimizu, Naohiro; Imanishi, Yuichirou (The Institute of Electrical Engineers of Japan, 2010)The purpose of this paper is to present and compare disinfection effect of plasma by means of Atmospheric Pressure Glow plasma and streamer discharge. Geobacillus stearothermophilus was used as biological indicator for ... -

Study on the antifungal effect of atmospheric-pressure microplasma excited by high-repetition-rate inductive energy storage
Siti Khadijah, Za'aba, Dr.; Katayama-Hirayama, Keiko; Akitsu, Tetsuya; Shimizu, Naohiro; Imanishi, Yuichirou (Institute of Electrostatics Japan, 2009-09)Atmospheric microplasma in a plane-parallel configuration was excited by high-repetition-rate inductive energy storage. We studied (1) the homogeneity of the microplasma device and (2) the inactivation efficacy for Aspergillus ...
