“…For instance, one-dimensional (1D) and two-dimensional (2D) jet arrays have been developed [10][11][12][13][14][15][16] and a few of them have been applied in materials processing and plasma biomedicine with satisfactory results. [15][16][17] In a single plasma jet, the effects of fluid field, electrical field, and device structure on the electrical characteristics, propagation dynamics, and plume length have been widely investigated with optical and electrical diagnosis, ICCD imaging, and Schlieren photography. [18][19][20][21][22][23] It has been found that the plasma plume propagates in different modes, [10,24] there are strongly nonlinear coupling effects of ionization waves determining streamer propagation, [25] the gas heating is the dominant factor for the transition of laminar to turbulent of plasma jet and the plume length, [3,26] and the linear-field and cross-field structures APPJs have also been compared and studied.…”

Atmospheric Pressure Plasma Jet (APPJ) arrays are considered as one of the most promising methods for uniform plasma processing of large uneven surfaces. To improve the downstream uniformity and enhance the surface treatment effects, it is important to reveal the mechanisms of the jet‐to‐jet interactions of plasma plumes in the jet array. In this paper, the electrical, optical, and fluid characteristics of the He and Ar three‐channel one‐dimensional (1D) plasma jet arrays with cross‐field needle‐ring electrode structure are studied and compared. It is found that there are divergences in the outside plumes of the propagation trajectory by the repellency of the plasma bullets and the spatial uniformity of the He and Ar plasma jet arrays can be improved with a lower applied voltage and a higher gas flow rate. The deflection angle of side plumes with respect to the central one of He is larger than that of Ar jet array due to the lighter molecular weight and better discharge synchronization. The experimental results show that Ar jet array is more controllable and stable and is more suitable for the design of the practical, simpler, and cheaper scalable plasma jet arrays.

“…A ten-channel atmospheric pressure glow discharge jet has been purposed by Cao et al [3]. Nie reported a two-dimensional array of 7 jets with honeycomb configurations [4]. Moreover, he suggested that this configuration of array had no fundamental limitation to scale up and a 37-channel honeycomb-shaped array was presented to illustrate the scalability.…”

Classification numbers: PACS: 52.70.Kz, 52.80.TnAtmospheric pressure planar RF 13.56 MHz discharge in Ar gas generated in long gap is investigated. The discharge operation with and without dielectric barrier on the electrodes is studied as a function of the applied power and gas flow. The source afterglow is characterized and analyzed for possible large scale biomedical applications where low gas temperature is required. The discharge is studied by relative and absolute emission spectroscopy. The gas temperature as low as 330±50 K is determined from rotationalvibrational band of OH emission. The absolute value of the discharge continuum irradiation is used to determine the electron density and the electron temperature. The electron-atom and electron-ion contributions to the Bremsstrahlung radiation are calculated and compared with measured spectra. The electron density of 1.91×10 20 m -3 and electron temperature of 1.750.25 eV are measured in the discharge without dielectric barrier. It is found that presence of the dielectric has negligible effect on electron temperature whereas electron number density is almost 6 times lower in the discharge with dielectric barrier.

Tissue products are susceptible to microbial contamination from different sources, which may cause disease transmission upon transplantation. Terminal sterilization using gamma radiation, electron‐beam, and ethylene oxide protocols are well‐established and accepted, however, such methods have known disadvantages associated with compromised tissue integrity, functionality, safety, complex logistics, availability, and cost. Non‐thermal (cold) atmospheric pressure plasma (CAP) is an emerging technology that has several biomedical applications including sterilization of tissues, and the potential to surpass current terminal sterilization techniques. This review discusses the limitations of conventional terminal sterilization technologies for biological materials, and highlights the benefits of utilizing CAP.
