“…The major advantage of this system is that it does not require an electrode similar to DBD or jet plasma system (Kopuk et al., 2022). Corona discharge plasma system has more applications in the textile industry, environment, and medical use (Sumariyah et al., 2018). Corona plasma is the stream of charged particles, including ions and electrons, accelerated by an electric field at atmospheric pressure.…”

With the constant increase in protein demand globally, it is expedient to develop a strategy to effectively utilize protein, particularly those extracted from plant origin, which has been associated with low digestibility, poor techno-functional properties, and inherent allergenicity. Several thermal modification approaches have been developed to overcome these limitations and showed excellent results.Nevertheless, the excessive unfolding of the protein, aggregation of unfolded proteins, and irregular protein crosslinking have limited its application. Additionally, the increased consumer demand for natural products with no chemical additives has created a bottleneck for chemical-induced protein modification. Therefore, researchers are now directed toward other nonthermal technologies, including high-voltage cold plasma, ultrasound, high-pressure protein, etc., for protein modification. The techno-functional properties, allergenicity, and protein digestibility are greatly influenced by the applied treatment and its process parameters. Nevertheless, the application of these technologies, particularly high-voltage cold plasma, is still in its primary stage. Furthermore, the protein modification mechanism induced by high-voltage cold plasma has not been fully explained. Thus, this review meets the necessity to assemble the recent information on the process parameters and conditions for modifying proteins by high-voltage cold plasma and its impact on protein techno-functional properties, digestibility, and allergenicity.

“…At an initial concentration of 10 mg/l, 84% removal was achieved in 0.5 hours, oxidation of ammonia was tested with aeration maximizing removal by 4.5 to 9 times more than oxidation without aeration. Sumariyah et al [72] explained the difference between DBD and CD. The current ion saturation flow in the corona discharge system is more than the flow of dielectric barrier discharges.…”

The ammonia pollution/contamination reveals at the inlet of drinking water treatment plants, especially on Northern coast of Egypt, due to the drainage of sewage and industrial wastes from factories along the Nile River, resulting in more neutralization that clogs inlet of water treatment plants. Ammonia causes many diseases; some of them lead to coma or death. Excess ammonia also causes the winter dam in North Egypt to force the drinking water treatment stations to stop operation because of the high pollution load. Therefore, many researchers removed ammonia from drinking water as it was limited to 0.5 ppm in the European association and WHO. In this review, a criticizing summary of researches work (1983-2021) is presented where removal of ammonia by physical (i.e. adsorption, air stripping, and membrane distillation), biological, and chemical (oxidation, struvite, photocatalyst, cold plasma) methods were reviewed.

“…where K is a dimensional constant which is determined experimentally. In essence of the equation (1) and equation (2), By comparing the linear dependence of I/V versus V and I 1/2 versus V, Ferreira et al [5] found that for negative corona discharges equation (2) performs better in all the inter-electrode ranges than equation 1, and equation (2) may hold only when the interelectrode distance is greater than 15 mm. All these indicate the existence of some inconsistencies in the applications of the formula mentioned and that there were still no determinate answers.…”

In this work, both positive and negative corona discharge of pin-grid geometrical configuration was studied and the necessary modification of the general law of corona discharge was proposed. The current-voltage measurements were performed at room temperature and at different inter electrode separations. The variation of dimensional constant K and corona inception voltage Vo with pin-grid separations S were subjected into the general law of corona discharge using the least square fitting method in Log-Log scale. The relationship between corona current and different voltage (V-Vo) was investigated to find the acceptable value of exponent n. The least square fitting for all variations of corona parameters was based on the highest R-square value of obtained straight lines for individual measurements. It was found that value of exponent n for both polarities is larger compared to the empirical formula proposed previously for the general law of corona discharge.
