Understanding the interactions between ionized matter and neutral particles is a prerequisite for discovering their impact on natural phenomena. One such phenomenon electric wind, which supposedly occurs due to charged particle-neutral coupling in systems of weakly gases, but this mechanism remains unclear. Here, we report direct evidence that wind caused by an electrohydrodynamic force generated particle drag as result momentum transfer from electrons/ions neutrals. The model experiment...
The purpose of the present study is to evaluate potential plasma‐treated water (PTW) as an alternative synthetic sodium nitrite in loin ham manufacturing. Two brine solutions made were compared against PTW for curing ham. In comparison chemical brining resulted increased redness ( a *‐value), while allowing maintain low residual content and total bacterial counts. No significant differences found yellowness b lightness L lipid oxidation among treatment groups. Furthermore, manufactured using...
Deadly diseases caused by pathogenic bacteria and viruses have increasingly victimized humans; thus, the importance of disinfection has increased in medical settings as well food agricultural industries. Plasma contains multiple bactericidal agents, including reactive species, charged particles, photons, which can synergistic effects. In particular, chemicals formed aqueous solution during plasma exposure potential for high antibacterial activity against various bacterial infections. Here,...
The electron-atom neutral bremsstrahlung continuum radiation emitted from weakly ionized plasmas is investigated for electron density and temperature diagnostics. spectrum in 450–1000 nm the argon atmospheric pressure plasma found to be excellent agreement with formula momentum transfer cross-section given by Popović. In 280–450 nm, however, a large discrepancy between measured emissivities observed. We find that without accounting radiative H2 dissociation continuum, temperature,...
The atmospheric pressure plasma jet (APPJ) is a promising technology for inactivating waterborne pathogens by generating diverse reactive species under ambient conditions. However, uncertainties regarding the bacterial inactivation mechanisms persist due to varying findings in prior research. This study aimed clarify of two representative bacteria, Staphylococcus aureus (S. aureus, Gram-positive) and Escherichia coli (E. coli, Gram-negative), using an argon-based APPJ (Ar-APPJ) system...
The interaction of plasma with liquid generates nitrogen species including nitrite (NO(-) 2). Therefore, the color developing capacity plasma-treated water (PTW) as a source for meat curing was investigated in this study. PTW, which is generated by surface dielectric barrier discharge air, and increase treatment time resulted concentration PTW. PTW used study contains 46 ppm after 30 min. To evaluate effect on cured color, batters were prepared under three different conditions (control,...
Weakly ionized plasmas at or near 1 atm pressure, atmospheric-pressure plasmas, have received increasing attention due to their scientific significance and potential for use in a variety of applications, particularly medicine, agriculture, food. However, there is large imbalance between research on plasma physics which partly the considerable differences characteristics these compared with those low-pressure plasmas. This discrepancy related difficulty performing diagnostics highly...
Abstract Ozone (O 3 ), nitrogen oxides (NO x and reactive species (RNS) play critical roles in atmospheric-pressure plasma applications. Although it is crucial to individually quantify these understand plasmas increase their effectiveness, the lack of reliable cost-effective diagnostics makes this difficult for many researchers. To address problem, we introduce a new deconvolution method broadband ultraviolet–visible absorption spectra simultaneous measurement eight species—O , NO, NO 2 N O...
Atmospheric pressure plasma (APP) is an emerging nonthermal microbial inactivation technique. In this study, agar and raw chicken breast were inoculated with Escherichia coli treated APP jet based on cold arc plasma. The aim of study was to investigate the optimum conditions for treatment in order maximize efficiency E. inactivation. combination N2+O2 (10 standard cubic centimeters per minute) a longer time min) resulted highest plates distance 20 mm. samples dry wet showed similar...
