“…This is in marked contrast to the 40 kHz DBD, where the ultrasonic irradiation enhanced treatment efficiency only moderately [15][16][17][18]. The attachment of these functional groups on the surfaces will contribute to the increase in the polar component of surface energy and potentially improve the adhesion properties of the surfaces [5,[15][16][17][18][19][20].…”

“…Accordingly, the polar component of the surface energy of the GFRP was increased by the plasma treatment with ultrasonic irradiation. It is a significant contrast from the atmospheric pressure plasma treatment driven at approximately 40 kHz AC voltage, where only moderate improvement of wettability was observed with ultrasonic irradiation [15][16][17][18]20]. It is noted that the increasing wettability and the polar component of surface energy can most likely improve adhesion properties of the GFRP surfaces because of strong interaction with general adhesives [19].…”

“…It is further reported that simultaneous ultrasonic irradiation during the DBD treatment can enhance oxidation at the GFRP surfaces [15] and suppress arcing in air plasmas [16,17]. A gliding arc with and without ultrasonic irradiation was also used for the adhesion improvement of GFRP plates [19,20]. However, a 50 Hz DBD with ultrasonic irradiation is never attempted for plasma surface modification.…”

Glass-fiber-reinforced polyester (GFRP) plates are treated using a 50 Hz dielectric barrier discharge at a peak-to-peak voltage of 30 kV in helium at atmospheric pressure with and without ultrasonic irradiation to study adhesion improvement. The ultrasonic waves at the fundamental frequency of around 30 kHz with the sound pressure level of approximately 155 dB were introduced vertically to the GFRP surface through a cylindrical waveguide. The polar component of the surface energy was almost unchanged after the plasma treatment without ultrasonic irradiation, but drastically increased approximately from 20 up to 80 mJ m À2 with ultrasonic irradiation. The plasma treatment with ultrasonic irradiation also introduced oxygen-and nitrogen-containing functional groups at the GFRP surface. These changes would improve the adhesion properties of the GFRP plates.

In this work, a self-made microplasma jet system was used to conduct the qualitation and quantitation of inactivation with Escherichia coli as the target bacteria. The logarithmic concentration and the size of antimicrobial rings served as the evaluation parameters, respectively. The effect of various parameters on inactivation effect was studied. The results showed that the majority of bacteria had been inactivated in 30 s. The inactivation effect enhanced and then weakened with the increase of air flow rate, and receded as the extension of treatment distance. The effect with different carrier gases showed as follows: oxygen > air > nitrogen > argon. Meanwhile, the effect of different components of microplasma was studied in the optimum conditions (The flow rate was 5 L/min; inactivation distance was 2 cm). The results showed that electrically neutral active species was the main factor of inactivation rather than heating effect, ultraviolet radiation and charged particles. Finally the experiments of thallus change proved that microplasma jet had etching effect on cell membrane. It also found that microplasma could degrade organic material like protein. Furthermore, the images of scanning electron microscope (SEM) revealed the change of cell morphology step by step in the whole process of inactivation.

“…Irradiation of ultrasound can improve treatment effects of atmospheric pressure plasmas. The effect of ultrasound is considered to be thickness reduction of the boundary layer of a gas on a material surface (Kusano 2009;Kusano et al 2010Kusano et al , 2011aKusano et al , b, 2012bKusano et al , 2013aKusano et al , 2014aKusano et al , 2015Kusano et al , 2018. Due to the thickness reduction, the reactive species in a plasma can more easily approach the material surface.…”
