During the last two decades atmospheric (or high) pressure non-thermal plasmas in and contact with liquids have received a lot of attention view their considerable environmental medical applications.The simultaneous generation intense UV radiation, shock waves active radicals makes these discharges particularly suitable for decontamination, sterilization purification purposes.This paper reviews current status research on liquids.The emphasis is mechanisms physical characteristics.
Abstract Plasma treatment is often used to modify the surface properties of polymer films, since it offers numerous advantages over conventional modification techniques. In this paper, a polypropylene (PP) film plasma‐treated using dielectric barrier discharge (DBD) operating in air at medium pressure (5.0 kPa). The modified films are characterized contact angle measurements, XPS‐analysis and attenuated total reflectance‐Fourier transform infrared (ATR‐FTIR) spectroscopy. Results show that...
An atmospheric pressure plasma jet generated in Ar/water vapor mixtures has been investigated and the effect of water content on properties studied. Plasma (0.05%) mixture shows higher intensity OH radicals emission spectra than pure argon alone. density estimated from current measurement is order 1.5×1013 cm−3. Electron temperature as 0.97 eV Ar it decreases with an increase plasma. The gas determined by fitting experimental using Boltzmann plot method. increases addition to feed 620 K up...
Dc-excited discharges generated in water at the tip of a tungsten wire which is located orifice quartz capillary are investigated by time-averaged optical emission spectroscopy.
Electrical and optical emission properties of non-equilibrium atmospheric air discharges between a metal pin tap water anode/cathode are presented. With anode the glow type as is derived from short-exposure time plasma imaging electrical characteristics. Additionally, validity extrapolated scaling laws low pressure discharge supports these findings.In case cathode filamentary in nature at surface. In anode, diffuse down to 10 ns. The timescales on which filaments visible near region...
In this contribution, optical emission spectroscopy is evaluated and thoroughly analysed as a diagnostic to characterize plasmas in contact with liquids. One of the specific properties liquids strong OH(A–X) hydrogen lines. As an example 600 ns pulsed dc excited discharge Ar, He O2 bubbles water investigated by time resolved spectroscopy. It shown that production processes species plasma kinetics strongly influence spectrum. This complicates interpretation spectra but provides opportunity...
Electrical and optical emission properties of a burning plasma between liquid cathode metal anode are presented in this paper. The has constricted contact points at the is clearly filamentary nature near water surface.The voltage drop depends on conductivity rather than pH significantly different for distilled electrolyte solutions. An acidification due to always observed.The rotational temperature OH N2 bulk is, respectively, range 3200?3750?K 2500?2750?K. nitrogen typically two times...
In this paper it is shown that electronic quenching of OH(A) by water prevents thermalization the rotational population distribution OH(A). This means observed ro-vibrational OH(A–X) emission band (at least partially) an image formation process and determined not only gas temperature. The negative ions clusters for larger concentrations can contribute to non-equilibrium. above demonstrated in RF excited atmospheric pressure glow discharges He–water mixtures a parallel metal plate reactor...
The characteristics of plasma temperatures (gas temperature and electron excitation temperature) density in a pulsed-dc excited atmospheric helium jet are studied by relative absolute optical emission spectroscopy (OES). High-resolution OES is performed for the hydrogen lines determination through Stark broadening mechanism. A superposition fitting method composed two component profiles corresponding to different densities developed fit investigated lines. Electron orders magnitude 1021 1020...
An antimicrobial nano-silver non-woven polyethylene terephthalate (PET) fabric has been prepared in a three step process. The fabrics were first pretreated by depositing layer of organosilicon thin film using an atmospheric pressure plasma system, then silver nano-particles (AgNPs) incorporated into the dipping-dry process, and finally covered second 10-50 nm, which acts as barrier layer. Different surface characterization techniques like SEM XPS have implemented to study morphology chemical...
In negative corona discharges in ambient air different discharge modes can be observed. this paper the current regions corresponding to these are determined. The influence of anode geometry, resistivity, inter-electrode distance and gas flow on threshold currents that mark corona-to-glow glow-to-spark transitions is investigated. experimental data backed up by an analytical treatment ionization instability development within a local spot metallic resistive anodes.
