Abstract Several attempts have been made to deliver reactive oxygen and nitrogen species (RONS) produced by non-thermal plasma onto large surfaces in a controllable way compatible with skin treatments. In this paper, the effect of pulse frequency, range 0.5–20 kHz, on discharge behavior was studied tissue models evaluate potential treatment changes. This has done through electrical characterization, visualization helium flow (by Schlieren technique), jet modifications (ICCD imaging) RONS...
The biological effects induced by cold atmospheric plasmas (CAPs) on human tissues are mainly due to the production of reactive oxygen and nitrogen species (RONS). Some RONS also responsible for pH lowering treated medium. CAP-induced acidification has beneficial effect tissues, contributing anti-bacterial healing improvement observed in wound. In this work we investigated local a helium CAP treatment using tissue models made agarose gels with adjusted around 7.4 mimic generic organs or 5.5...
In this work, we developed transporting atmospheric pressure cold plasma using single electrode configuration through a sub-millimetre flexible dielectric tube beyond 100 cm. It was shown that the waveform of applied high voltage is essential for controlling upstream and downstream inside tube. regard, sawtooth enabled transport with less compared to sinusoidal pulsed form voltages. A string as long 130 cm obtained by only 4 kV peak-to-peak waveform. Optical emission spectroscopy revealed...
This study developed a stable transfer of He atmospheric pressure cold plasma bullets in large dielectric tube with length 70 cm and an inner diameter 0.4–1.6 cm. DC superimposed AC voltage was used for this purpose. The component the applied generated corona ionization through tube, which helped ignition as pre-ionization background. followed frequency component; therefore, very high energy not required to ignite large-scale plasma. To our knowledge, is first time such complex waveform has...
In this work, the surface modification of ultra‐high‐molecular‐weight polyethylene (UHMWPE), a linear polymer, by helium transporting discharge at atmospheric pressure was investigated means FTIR, AFM, XPS, ToF‐SIMS, and contact angle measurements. Two types configurations, that is, jet glow for treatment polymer substrates were studied. The results show position UHMWPE plays an important role in stability treatment. placed inside tube present more stable wettability modification. addition,...
In this article, we developed transporting plasma sources that operate at atmospheric pressure. The effect of electrode configuration on was investigated. order to increase the cross-section, converted a stream into four channels by cylindrical housing. Electron excitation and rotational temperatures were estimated using optical emission spectroscopy. Furthermore, electrical temporal characteristics plasma, discharge power charge deposition target propagation single multi-channel compared...
Blood viscoelasticity and plasma protein levels can play an important role in the diagnosis prognosis of cancer. However, histones DNA modulating blood clot properties remains to be investigated. This study investigates differences among cancer patients, individuals with other diseases, healthy individuals.
In this study, the characteristics of nanocrystalline diamond films synthesized at low surface temperature on Ti-6Al-4V (TA6V) substrates using a distributed antenna array microwave reactor aiming biomedical applications were investigated. The roughness TA6V is varied by scratching with emery paper 1200, 2400, 4000 polishing grit. Nanocrystalline (NCD) coatings morphology, purity, and microstructure comparable to those obtained silicon usually employed in same growth conditions are...
SiOx films were deposited using an atmospheric-pressure transporting discharge, and we adopted tetraethyl orthosilicate (TEOS) as the precursor. We studied effects of nozzle-substrate distance, applied power, deposition time, precursor inlet positions on substrates placed at tube exit. The thin investigated field-emission scanning electron microscopy attenuated total-reflection Fourier-transform infrared spectroscopy. specific studies that carried out showed a clear relationship between...
