“…In the study of plasma [1][2][3][4][5][6][7] particles, there is a ground breaking tool available in the literature named the "Vlasov Maxwell system", which is the amalgamation of the Vlasov equation and Maxwell equations. The Vlasov and Maxwell equations (MEs) are actually the mathematical formulation of performance of plasma particles and electro-magnetic field, formulated by well-known scientists Anatoly Vlasov (1938) and James Clerk Maxwell (1862), respectively.…”

We integrate fractional calculus and plasma modelling concepts with specific geometry in this article, and further formulate a higher dimensional time-fractional Vlasov Maxwell system. Additionally, we develop a quick, efficient, robust, and accurate numerical approach for temporal variables and filtered Gegenbauer polynomials based on finite difference and spectral approximations, respectively. To analyze the numerical findings, two types of boundary conditions are used: Dirichlet and partial slip. Particular methodology is used to demonstrate the proposed scheme’s numerical convergence. A detailed analysis of the proposed model with plotted figures is also included in the paper.

Abstract-In this study, decomposition of methane hydrate using argon plasma jet investigated in the pressure range of 0.1MPa to 2.0MPa. The plasma generated under the high-pressure condition, which is difficult to achieve when using radio frequency (RF) plasma in the liquid method. By using emission spectrometer analysis, the excitation temperature is found to increase as the gas pressure increases, whereas, it decreases as the argon flow rate increases. During the process of plasma irradiation, the required essential reactions for methane hydrate decomposition, such as methane hydrate dissociation (MHD), steam methane reforming (SMR), and methane cracking reaction (MCR) were not completely satisfied due to an insignificant amount of methane. The gas chromatography analysis confirmed that the methane cracking reaction (MCR) was only occurred to generate hydrogen and the C (s) , due to the absence of C 2 H 2 and C 2 H 4 as the byproducts. In comparison with the other primary reactions of methane hydrate decomposition, steam methane reforming reaction became dominant in converting methane into hydrogen. Although the hydrogen production efficiency is less than that of radio frequency plasma in liquid, the reduction of CO 2 by the thermal decomposition of Teflon from CO making it possible is considered as an advanced promising technique in the future.

“…The determining role is played by the magnetizable phase. The latter may be in the form of iron nanoparticles [11,12], colloidal magnetic nanoparticles [13,14], octopusshaped magnetizable microparticles [15], iron microtubes [16], iron microspheres and/or iron pore microspheres [17,18] and iron oxide nano-microfibers [19], generated by plasma processes. Their size and shape are controlled by the electro-thermal parameters of the plasma and by the quantities of thermally processed materials in inert or oxidizing gas environments [11][12][13][14][15][16][17][18][19].…”

From liquid solutions, based on the nano-microfibers of iron oxides and silicone oil, magnetorheological suspensions are obtained whose electrical properties are useful in making magnetically active composites [20].…”
