The dielectric barrier discharge has attracted the interest of many researchers in several fields since it produces a non-thermal plasma at atmospheric pressure. Its field application is totally vast and includes medicine, biotechnology, chemistry, various other science technology because physical chemical properties that characterize jet based on discharge. These are characterized by different...

Arrays of atmospheric-pressure plasma jets are being considered as a means to increase the area being treated in surface modification and in plasma medicine in particular. A unique challenge of scaling plasma jet arrays is that individual plasma jets in an array tend to interact with each other, which can lead to quenching of some individual jets. To investigate these potential interactions, a ...

Cold atmospheric pressure plasmas (CAPPs) have emerged over the last decade as a new promising therapy to fight cancer. CAPPs' antitumor activity is primarily due to the delivery of reactive oxygen and nitrogen species (RONS), but the precise determination of the constituents linked to this anticancer process remains to be done. In the present study, using a micro-plasma jet produced in helium ...

OBJECTIVE To study the effect of atmospheric pressure plasma (APP) jet as a potential accelerator of the degradation of hydrogen peroxide in bleaching gels which could lead to better and faster bleaching. MATERIAL AND METHODS 25 pastilles of hydroxylapatite were colored in green tea for 8 hours and were randomly divided into five groups (n = 5). The bleaching process was performed with 30% an...

Broadband ultraviolet absorption spectroscopy is employed to measure absolute number density of C2 and CH radicals in the boundary layer of an atmospheric DC plasma assisted chemical vapor deposition (CVD) system. High spatial resolution (125 μm) is achieved by using a spatial filter and a ultra-bright argon mini-arc light source. The spectra of D Σu←X Σg electronic transition of C2 and C Σ←X ∏...

In this paper, the ground state OH density is measured in high pressure plasma by laser-induced fluorescence (LIF) spectroscopy. The OH density determination is based on the simulation of the intensity fraction of fluorescence from the laser-excited level of OH (A) in the total detected LIF signal. The validity of this approach is verified in an atmospheric pressure Ar + H2O plasma jet sustaine...

Cold plasma is recognized and explored for a plethora of applications in the food agricultural industry. This study investigated influence continuous atmospheric pressure non-thermal jet system on mortality Rhyzopertha dominica adults whole wheat kernels changes milling physicochemical attributes treated wheat. Air-filled packets were artificially infested with R. adults. The packages carried b...

Atmospheric pressure single electrode argon /oxygen plasma jet has been generated between a high-voltage electrode and the surrounding room air for treating thermally sensitive materials is reported. The discharge has been characterized by electrical and optical emission spectroscopic technique. The microplasma jet device operated by an electrical power less than 10 W exhibited a long plasma je...
