“…It could be possible by thermal and non-thermal technologies while preserving all the nutrients of the food. Though thermal technologies might reduce the microbes' counts, they also degrade the quality by destroying the heatsensitive vitamins and micronutrients [4]. Alternatively, irradiation, low-temperature plasma technique, pulsed electric field, high hydrostatic pressure, pulsed UV-light, and ultrasound processing are some non-thermal techniques for the inactivation or reduction of the microbial load on various food items.…”

“…Disinfection/Sterilization of different kinds of equipment in the bio-medical field is necessary to avoid unnecessary secondary infections caused due to pathogens. Various techniques are used to sterilize medical equipment, such as the use of ethylene oxide, peracetic acid, hydrogen peroxide, formaldehyde, exposure to UV, treatment with gamma-ray, and autoclaving [4]. Table 2 signifies the different existing processes and the pros and cons of utilizing these techniques.…”

“…When the excited particles relax to low energy states, we see the plasma glow. Plasma breakdown voltage between the electrodes for a specific gas depends on the pressure and the distance between the electrodes, according to Paschen's Law [2,3] and with this breakdown voltage, electrons are generated that later contribute to electron avalanches and secondary electron emission processes [4]. Figure 1 shows the breakdown voltage for various gases as a function of the product of pressure and distance between the electrodes.…”

Cold atmospheric plasma (CAP) is a promising technology quite useful in many industries including biotechnology, biomedical, textiles, and food processing. The contrivance of plasma technology can be a potential game-changer to use in any possible way in these industries. This CAP technology is technically a green process with no generation of chemically harmful substances with more ecological and economic benefits. This review article will focus on the research done in the textile industry and food processing, how plasma brings in an effective change in these industrial sectors as well the as application of CAP in disinfection, sterilization, microbial inactivation, and surface modification to obtain desirable results. Recently, there have been reports of successful use of CAP technology for surface inactivation of SARS-CoV-2, plasma-activated water for disinfection of SARS-CoV-2. This article will streamline the innovations in textiles and food industries achieved using plasma technology and what gaps industries face while manufacturing. The focus will be on what research has already done while depicting the gaps and opportunities for using plasma technology in these industries and making use of it to achieve a circular economy, which is one of the major policies of the European countries. A circular economy enables manufactures to produce goods which can be reused, recycled, refurbished, and repaired rather than scrapping them after a single use. The reduction of harmful chemicals, wastewater treatment, and sterilization is achieved using plasma technology and allows reusing the resources which consequently helps to achieve most of the UN’s sustainable development goals and help society to live a sustainable and better life.

“…The aim of the multifractal approach is to offer generalist laws that could unify different aspects of the laser-matter interactions. We previously tackled processes like plasma self-structuring, particle distribution in a single element and complex alloys, spatial-temporal evolution of certain plasma parameters, and even charge particle oscillations [30][31][32][33][34][35][36][37]. All these results were achieved by admitting that the ejected particles move on continuous but nondifferentiable curves.…”

Non-Linear Behaviors of Transient Periodic Plasma Dynamics in a Multifractal Paradigm

et al. 2020

View full text Add to dashboard Cite

In a multifractal paradigm of motion, nonlinear behavior of transient periodic plasmas, such as Schrodinger and hydrodynamic-type regimes, at various scale resolutions are represented. In a stationary case of Schrodinger-type regimes, the functionality of “hidden symmetry” of the group SL (2R) is implied though Riccati–Gauge different “synchronization modes” among period plasmas’ structural units. These modes, expressed in the form of period doubling, damped oscillations, quasi-periodicity, intermittences, etc., mimic the various non-linear behaviors of the transient plasma dynamics similar to chaos transitions scenarios. In the hydrodynamic regime, the non-Newtonian behavior of the transient plasma dynamics can be corelated with the viscous tension tensor of the multifractal type. The predictions given by our theoretical model are confronted with experimental data depicting electronic and ionic oscillatory dynamics seen by implementing the Langmuir probe technique on transient plasmas generated by ns-laser ablation of nickel and manganese targets.

“…Studied for the past two to three decades for their potential novel application for medical applications, particularly wound treatment and decontamination, cold atmospheric pressure plasmas (CAPPs) are becoming increasingly closer to clinical applications for emergency workers and the warfighter. A plasma is formed when a gas is exposed to a sufficiently strong applied voltage, or electric field, to cause electrical breakdown, or discharge formation [8]. During this discharge formation, CAPPs form reactive oxygen species (ROS), reactive nitrogen species (RNS), reactive oxygen nitrogen species (RONS), and charged particles that can influence biological systems [9].…”

Despite the high overall survival rates of severely injured military and civilian personnel requiring trauma and acute care, the challenges of treating infections and healing-resistant wounds have grown. Exposure to unknown environmental pathogens at the wound, including parasites and antibiotic resistant microorganisms, hinders timely and effective treatment using traditional techniques. Cold atmospheric pressure plasma (CAPP) provides a promising biophysical tool to address these issues by applying physically created modalities that cannot be circumvented by bioresistance to inactivate microorganisms and enhance wound healing. CAPPs generate charged particles and numerous reactive oxygen species (ROS) and reactive nitrogen species (RNS) that act on biological cells and tissues, often through plasma membrane interactions. This review fills a gap in the plasma medicine literature by specifically focusing on applying CAPPs for acute trauma, such as surgery, wound treatment, and disinfection. After briefly highlighting the areas of opportunity for improving acute trauma treatment and the fundamentals of CAPP generation, this review details emerging applications of CAPPs for enhanced wound healing, burn treatment, transdermal delivery, and surgical applications. We also discuss CAPP optimization through novel device design and synergistic combination with traditional treatment technologies to transition this biophysical technology to the battlefield and acute care settings.
