## 2 Review of Special Issue Contents  
Contributions to this Special Issue focus on different aspects of Atmospheric-Pressure Plasma Technology, giving valuable examples of applied research in the field. This Special Issue of _Applied Sciences_, \"Recent Advances in Atmospheric-Pressure Plasma Technology\", includes one review [3] and eight original papers [4; 5; 6; 7; 8; 9; 10; 11], providing new insights into the application of atmospheric pressure plasma technology. [PERSON] et al [3] discussed the application of cold atmospheric pressure plasma (CAPP) technology in different configurations. Their manuscript outlines the application of CAPP in medicine for the inactivation of various pathogens (e.g., bacteria, fungi, viruses, sterilization of medical equipment, and implants) in the food industry (e.g., food and packing material decontamination), agriculture (e.g., disinfection of seeds, fertilizer, water, soil). In medicine, plasma also holds great promise with regard to direct therapeutic treatments in dentistry (tooth bleaching), dermatology (atop eczema, wound healing), and oncology (melanoma, glioblastoma). [PERSON] et al. [4] discussed the changes induced in the atmospheric pressure plasma jets (APPIs) characteristics of the gas mixture; more precisely, argon/oxygen (Ar/O\({}_{2}\)) mixture. The voltage-current waveform signals of APPJ discharge, gas flow rate, photo-imaging of the plasma jet length and width, discharge plasma power, axial temperature distribution, optical emission spectra, and irradiance were investigated. [PERSON] et al. [5] focused on fabrication and physicochemical properties investigations of silica-multiwalled carbon nanotubes/poly(dimethylsiloxane) composite coatings deposited on the glass supports activated by cold plasma in air or argon. They found that the type of plasma influences the surface properties of the deposited coating. [PERSON] et al. [6] realized a two-dimensional numerical model to simulate operation conditions in the non-transferred plasma torch, used to synthesis nanosilica powder. The numerical results showed good correlation and good trends with the experimental measurement. This study allowed us to obtain more efficient control of the process conditions and better optimization of this process in terms of the production rate and primary particle size. [PERSON] et al. [7] realized an evaluation of the effect of plasma gas species and temperature concerning the reactive species produced and the bactericidal effect of plasma. Nitrogen, carbon dioxide, oxygen, and argon were used as the gas species, and the gas temperature of each plasma varied from 30 to 90 \(\circ\)C. The results demonstrate that the plasma gas type and temperature have a significant influence on the reactive species produced, and the bactericidal effect of plasma and the disinfection process could be improved by properly selecting the plasma gas species and temperature. [PERSON] et al. [8] design and build a multi-gas temperature-controllable plasma jet that can adjust the gas temperature of plasmas with various gas species and evaluated its temperature control performance. By varying the plasma jet body temperature from \(-30\)\(\circ\)C to 90 \(\circ\)C, the gas temperature was successfully controlled linearly in the range of 29-85 \(\circ\)C for all plasma gas species. [PERSON] et al. [9] realized a single dielectric barrier discharge (SDBD)-based actuator. The consumed electric power was measured, and the optical emission spectrum was recorded in the ultraviolet-near infrared (UV-NIR) range. The average temperature of the neutral species over the actuator was found to be around 410 K at the maximum power level. [PERSON] et al. [10] reported a dielectric barrier discharge (DBD) plasma rotational reactor for the direct treatment of wheat flour. The primary research goal was to determine the effects of short-period cold plasma treatment of DBD type on flour and dough properties.
