The plasma-modified clinoptilolite (PMC) nanorods were prepared from natural (NC) utilizing environmentally-friendly corona discharge plasma. PMC and NC characterized by XRD, FT-IR, SEM, EDX, XPS BET, which confirmed the nanocatalyst formation. catalytic performance of in heterogeneous sono-Fenton-like process was greater than for treatment phenazopyridine (PhP). desired amounts obtained experimental parameters including initial pH (5), dosage (2g/L), K2S2O8 concentration (2mmol/L),...
In the present study, properties of natural clinoptilolite were successfully modified by a glow discharge plasma technique. A thorough characterization was performed to clarify morphology, chemical composition, and porosity untreated plasma-treated clinoptilolites. The scanning electron microscopy images clinoptilolites demonstrated that morphology changed from microparticle nanorod after treatment. Brunauer–Emmett–Teller results showed treatment has enhanced specific surface area up 2-fold...
A new model for plasma behaviour in Filippov type focus (PF) systems has been described and used. This is based on the so-called slug Sing Lee's Mather PF devices. Using model, discharge current its derivative as a function of time, pinch time maximum pressure, have predicted. At end, predicted data are compared with experimental obtained through facility nominal energy 90 kJ.
The aim of this study was to modify surface properties immobilized rutile TiO₂ using Argon cold plasma treatment and evaluate the performance catalyst in photocatalytic elimination synthetic dyes UV/TiO₂/H₂O₂ process. surface-modified characterized by XRD, EDX, SEM, UV-DRS XPS analyses. Response methodology adopted achieve high efficiency evaluating effect two main independent parameters (exposure time pressure) on modification catalyst. increase operation pressure led higher decolorization...
This study aimed to investigate the efficacy of DBD cold plasma (CP) on carrot juice quality maintenance and develop suitable shelf life models based carotenoid degradation total mesophilic bacteria (TMB) growth. The physicochemical, microbial, sensory properties treated with CP (8, 10, 12 kV for 3 min) heat (80 °C 7 were evaluated during storage at 4 21 days. Results showed treatment lowest voltage (8 kV) better preserved physicochemical (ascorbic acid phenol), color changes, microbial...
Pyrite ores were converted to pyrite nanostructures using N<sub>2</sub>plasma for use as effective reusable catalysts in the heterogeneous Fenton process.
Ion-acoustic solitons in a collisionless plasma consisting of warm ions, hot isothermal electrons, and relativistic electron beam are studied by using the reductive perturbation method. The basic set fluid equations is reduced to Korteweg–de Vries (KdV) modified (mKdV) equations. effects ion temperature on ion-acoustic investigated. It has been shown that four modes can be propagated this system. compressive rarefactive satisfies KdV equation for given soliton velocity, density much smaller...
The presence of pesticide residues in food products and water leads to adverse health environmental effects. In an emerging field research, a range non-thermal physical techniques has recently been identified as suitable substitutes for the conventional residue removal method. These strategies not only exert no negative effects on quality but also increase shelf life through inhibiting or eliminating harmful bacteria toxins. This review focuses efficiency mechanism action several elimination...
We use multifractal detrended fluctuation analysis (MF-DFA) to study the electrical discharge current fluctuations in plasma and show that it has properties behaves as a weak anti-correlated process. Comparison of MF-DFA results for original series with those shuffled surrogate shows correlation is responsible nature current.
Ni/Al2O3 catalyst promoted by Co and ZrO2 was prepared co-impregnation method treated with glow discharge plasma. The catalytic activity of the synthesized nanocatalysts has been tested toward conversion CH4/CO2 to syngas. physicochemical characterizations like XRD, EDX, FESEM, TEM, BET, FTIR, XPS show that plasma treatment results in smaller particle size, more surface concentration, uniform morphology. dispersion nickel plasma-treated nanocatalyst also significantly improved, which helpful...
