Green synthesis of high throughput hydrogen peroxide via sub-atmospheric plasma-water interaction.

Plasma-activated water (PAW), enriched with reactive species such as hydrogen peroxide (HO), presents a sustainable and versatile solution for wastewater treatment, disinfection, agriculture, and biomedical applications. This study investigates the effects of key plasma parameters - treatment time, input power, water purity, and chamber pressure - on HO production. A statistical framework combining response surface methodology (RSM), regression analysis, ANOVA, effect estimation, and marginal means was employed to model and analyze these influences.

Investigating the efficacy of plasma washing for stains removal.

The study explores the effectiveness of plasma washing as an environmentally sustainable method for fabric stain removal. Utilizing a dielectric barrier discharge pencil plasma jet (DBD-PPJ) with air as the plasma-forming gas, we assessed its stain removal efficacy on various stains (ink, turmeric, mud/soil, grass, coffee, and oil) on white cotton fabric. Results indicate that plasma washing efficiently removes stains, with increased detergency over time.

Investigating the effects of microwave plasma on bacterial cell structures, viability, and membrane integrity.

Plasma-mediated bacterial inactivation holds great promise but presents several challenges. This study investigates the antibacterial effect of 2.45 GHz non-thermal microwave (MW) plasma on Staphylococcus aureus (S.

Green synthesis of ammonium nitrate (NHNO) fertiliser: production via plasma water/ice interaction with air and NH plasma.

This study introduces a green and sustainable method for synthesising ammonium nitrate (NHNO) using plasma activated water (PAW). Nitrate ions () were generated via air plasma treatment, and ammonium ions () were introduced using low pressure ammonia (NH₃) plasma exposure to nitrate-rich PAW in frozen form to produce NHNO. Results demonstrated that process parameters, including NH₃ gas pressure, applied voltage, and treatment time, significantly influenced PAW properties, with NH₃ plasma treatment time showing the most substantial impact.

Methotrexate degradation in artificial wastewater using non-thermal pencil plasma jet.

The rising global cancer rate is driving up the consumption of anticancer drugs. This causing a noticeable increase in the levels of these drugs in wastewater. The drugs are not metabolized effectively by the human body, leading to their presence in human waste, as well as in the effluent from hospitals and drug manufacturing industries.

Investigation of Antimicrobial Activity of DBD Air Plasma-Treated Banana Fabric Coated with Natural Leaf Extracts.

This paper focuses on the investigation of the antimicrobial activity of banana fabric treated with dielectric barrier discharge (DBD) plasma. The fabric was exposed to air plasma for varying treatment times of 1-5 min followed by coating with green tea () and tulsi () leaf extracts at five different concentrations. The treated fabric was evaluated in terms of surface wettability by a range of tests like wet-out time analysis, hydrophilicity test, and contact angle measurements.
