It remains a challenge to generate the uniform and large-area cold plasma at atmospheric pressure. In this paper, we report a method to generate a reliable and homogeneous brush-shaped plasma plume running at atmospheric pressure. The plasma brush (110 mm in length and 10 mm in width) is mainly composed of well-aligned and hollow optical fibers.(More)
Atmospheric-pressure N2, He, air, and O2 microplasma arrays have been used to inactivate Escherichia coli cells suspended in aqueous solution. Measurements show that the efficiency of inactivation of E. coli cells is strongly dependent on the feed gases used, the plasma treatment time, and the discharge power. Compared to atmospheric-pressure N2 and He(More)
At temperatures above 350 degrees C, significant amounts of NOx formed from N2 and O2 have been observed in Cu-ZSM-5 catalyst-pellet filled dielectric barrier discharges, indicating the necessity of using low-temperature performance in all plasma-catalytic processes for removal of air pollutants.
In this paper, we report on the propagation behavior of the atmospheric-pressure and brush-shaped He/O<sub>2</sub> plasma plumes generated by a specially designed plasma device. The measurements show that the frequency of applied voltage (f) and the O<sub>2</sub> fraction and flow rate of the feed gas significantly affect the discharge propagation of the(More)
Tussah pebrine disease resulting from Nosema bombycis (NB) spores causes massive production and economic losses in the silk industry in China. This paper reports on highly effective inactivation of NB spores for the control of pebrine disease by using an atmospheric pressure cold plasma jet. Both Giemsa dyeing measurement and tussah breeding experiment show(More)
