introduction the aim of this study was toinvestigate the sterilization potential of atmospheric pressure plasma jet (appj) and interactions of this technology with double-stranded dna using the polymerase chain reaction (pcr) and single-strand conformation polymorphism (sscp) techniques. materials and methods the plasma jet was produced through a high voltage sinusoidal power supplyusing a mixt...

The use of atmospheric pressure plasma jets (APPJs) in plasma medicine have produced encouraging results in wound treatment, surface sterilization, deactivation of bacteria, and treatment of cancer cells. It is known that many of the reactive oxygen and nitrogen species produced by the APPJ are critical to these processes. Other key components to treatment include the ion and photon fluxes, and...

Tunable diode laser absorption spectroscopy (TDLAS) has been applied to measure the absolute production rate of NO molecules in the gas phase of an atmospheric pressure plasma jet (APPJ) operating at rf (13.56 MHz) in argon with small (up to 1%) admixtures of air. The resulting NO production rates were found to be in the range (0.1–80)× 10−3 sccm or (0.05–35)× 1018 molecules s−1 depending on th...

We use screen printing to deposit LiCl + Ni(NO 3 ) 2 ·6H O pastes on a flexible carbon cloth substrate and then calcine it using nitrogen atmospheric-pressure-plasma jet (APPJ). Through the high-temperature treatment by APPJ, can be rapidly converted into Li-Ni oxides (LNOs). The LNOs are used as electrodes of gel-electrolyte Li-ion hybrid supercapacitors (Li-ion HSCs). best areal capacity 21.0...

Atmospheric pressure plasma jets (APPJs) are being investigated in the context plasma medicine and biotechnology applications, and surface functionalization. The composition of the surface being treated ranges from plastics, liquids, and biological tissue, to metals. The dielectric constant of these materials ranges from as low as 1.5 for plastics to near 80 for liquids, and essentially infinit...

Different cold atmospheric plasma (CAP) sources are used for a variety of applications and produce a variety of different reactive species based on operating conditions such as gas chemistry and operating voltage. Direct comparisons of these different sources and understanding of how local environment near the target can affect the flux of species and high energy photons are lacking. Experiment...

Plasma treatments are common for increasing the surface energy of plastics, such as polypropylene (PP), to create improved adhesive properties. Despite the significant differences in plasma sources and plasma properties used, similar effects on the plastic film can be achieved, suggesting a common dominant plasma constituent and underpinning mechanism. However, many details of this process are ...

This study discussed the effect of oxygen impurity in inlet gas a nitrogen atmospheric pressure plasma jet (APPJ). A numerical model that takes into account fluid dynamics, heat transfer, mass diffusion, and chemical reactions was developed to simulate APPJ. Further, DC APPJ experiment performed verify temperature characteristics on treated surface. The decreased with an increase impurity. More...

Gas-liquid interfacial atmospheric-pressure plasma jets (GLI-APPJ) are used medically for plasma-induced cell-membrane permeabilization. In an attempt to identify the dominant factors induced by GLI-APPJ responsible for enhancing cell-membrane permeability, the concentration and distribution of plasma-produced reactive species in the gas and liquid phase regions are measured. These reactive spe...
