“…Plasma treatment time to activate water also plays a key role in PAW inactivation efficacy. In principle, longer treatment time leads to greater physicochemical changes of PAW, including more acidic pH, higher concentration of reactive species, which have been demonstrated by many studies (Kinandana et al, 2018;Vlad & Anghel, 2017;Zhang et al, 2016Zhang et al, , 2017. Plasma treatment time has been proved to be in a positive correlation with inactivation efficacy (Bakovsky, Fantova, & Chumachenko, 2016;Qi et al, 2018;Zhang et al, 2016).…”

“…(2017) investigated the effect of various distance (from 1 to 4 mm) on the formation of N 2 and OH species close to the water surface, and results showed that the OH concentration was reduced when the gap distance was increased, while the electron density was increased with increased distance, suggesting the particular production of RONS can be tailored via changing the distance. Kinandana, Sumariyah, and Nur (2018) demonstrated that the maximum reactive species (dissolved O 3 and H 2 O 2 ), as well as the most acidic pH were obtained when the distance was 2 cm compared to 1 or 3 cm.…”

Novel nonthermal inactivation technologies have been increasingly popular over the traditional thermal food processing methods due to their capacity in maintaining microbial safety and other quality parameters. Plasma-activated water (PAW) is a cutting-edge technology developed around a decade ago, and it has attracted considerable attention as a potential washing disinfectant. This review aims to offer an overview of the fundamentals and potential applications of PAW in the agri-food sector. A detailed description of the interactions between plasma and water can help to have a better understanding of PAW, hence the physicochemical properties of PAW are discussed. Further, this review elucidates the complex inactivation mechanisms of PAW, including oxidative stress and physical effect. In particular, the influencing factors on inactivation efficacy of PAW, including processing factors, characteristics of microorganisms, and background environment of water are extensively described. Finally, the potential applications of PAW in the food industry, such as surface decontamination for various food products, including fruits and vegetables, meat and seafood, and also the treatment on quality parameters are presented. Apart from decontamination, the applications of PAW for seed germination and plant growth, as well as meat curing are also summarized. In the end, the challenges and limitations of PAW for scale-up implementation, and future research efforts are also discussed. This review demonstrates that PAW has the potential to be successfully used in the food industry.

“…The important advantages of this system are that it is small and lightweight with a compact design. It is easy to use and can be constructed from cheap, readily available components (Huang et al, 2018;Kinandana et al, 2018;Jung et al, 2022). This research demonstrates the possibility of changing the characteristics of the Al/PVA films by an annealing process to obtain Al 2 O 3 thin films and improve their general performance (Lee, 2013;Baggetto et al, 2015;Parauha et al, 2021).…”

Alumina thin films have significant applications in the areas of optoelectronics, optics, electrical insulators, sensors and tribology. The novel aspect of this work is that the homogeneous alumina thin films were prepared in several stages to generate a plasma jet. In this paper, aluminium nanoparticles suspended in vinyl alcohol were prepared using exploding wire plasma. TEM analysis was used to determine the size and shape of particles in aluminium and vinyl alcohol suspensions; the TEM images showed that the particle size is 17.2 nm. Aluminium/poly vinyl alcohol (Al/PVA) thin films were prepared using this suspension on quartz substrate by plasma jet technique at room temperature with an argon gas flow rate of 1 L/min. The Al/PVA thin films were thermally converted to alumina films, where they were annealed at different temperatures (700, 800, or 900°C). X-ray diffraction (XRD), atomic force microscopy (AFM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) techniques were used to characterise these thin films before and after annealing process. The diffraction patterns of the prepared thin films before subjecting them to the annealing process indicated the presence of peaks belonging to aluminium and PVA; however, the diffraction patterns and FTIR spectra obtained for these films after the annealing process showed peaks indicating the formation of alumina films of different phases. AFM and SEM investigations proved that the formed particles for all prepared films before and after the annealing process were similar in size and almost spherical; the diameter of the particles was on the order of a few nanometres. To control the properties of prepared thin films, the plasma which was used to produce thin films is diagnosed spectrophotometrically. The generated plasma was diagnosed using optical emission spectroscopy to estimate the electron temperature Te; the electron temperature was 1.925 eV.

“…Plasma‐facing liquids (PFLs), one type of plasma‐activated liquid, have attracted considerable research attention in terms of the elucidation of its physicochemical properties and the expansion of its application scope. Plasma‐activated liquid refers to all liquid affected by plasma discharge, while PFL has the advantage of being more efficient in that it can supply short‐lived chemical species directly to the liquid surface because the plasma discharge plume faces the liquid surface [22–26] . In particular, when using inert gas such as He as discharge gas, it has the great advantage of being able to keep the temperature of the plasma jet low, so it is particularly strong in the bio‐field where maintaining an appropriate temperature is required.…”

Plasma‐facing liquids (PFLs) facilitate the storage of reactive O and N species (RONS), including H2O2 and NO2−, which remain in the PFL after plasma treatment, and they can continuously influence the target immersed in the liquid. However, their behaviors and levels of generation and extinction depend strongly on the plasma characteristics and liquid condition. Therefore, understanding the effects of the liquid type on the plasma discharge characteristics and the RONS generated via plasma discharge is necessary. We compared the RONS generation and storage trends of deionized H2O and a high‐conductivity PFL, RPMI 1640, which is a well‐known cell culture medium commonly used to culture mammalian cells. RPMI 1640 acted as an electrode and enhanced the plasma discharge power by supplying abundant radicals and RONS. The production of gaseous hydroxyl radicals and NO markedly increased, which facilitated H2O2 and NO2− production in the PFL for the first 200 s, and then the increase in the RONS concentration stagnated. With respect to storage, as the components within RMPI 1640 exhibited high reaction constants for their reactions with H2O2, H2O2 elimination was completed in <30 min. Unlike H2O2, the concentration of NO2− in the PFL was unchanged.
