27 Feb 2021TL;DR: In this paper, the influence of hybrid nanoparticles on the dusty liquid flow through a stretching cylinder by employing the modified Fourier heat flux law was explored by employing two phase model to characterise the fluid flow.
Abstract: The current paper explores the influence of hybrid nanoparticles on the dusty liquid flow through a stretching cylinder by employing the modified Fourier heat flux law. Two phase model is implemented in the present research to characterise the fluid flow. Molybdenum disulphide and silver are used as nanoparticles suspended in base fluid water. The equations which represent the described flow are changed into a set of ordinary differential equations by opting appropriate similarity variables. The reduced dimensionless nonlinear ODEs are numerically solved out by using Runge–Kutta–Fehlberg fourth fifth order inclusive of shooting approach. The impact of several dimensionless parameters over velocity and thermal gradients are deliberated by using graphs. Graphical illustrations for skin friction are also executed. Result outcome reveals that, rise in values of mass concentration of particle declines the velocity and thermal gradient of both dust and fluid phases and cumulative in curvature parameter upsurges the velocity and thermal gradient within the boundary. Further, the heightening of thermal relaxation parameter enhances the thermal profile of both fluid and dust phases.

01 Nov 2020TL;DR: In this paper, NiFe2O4 NPs were synthesized via simple and cost effective sonochemical method and X-ray diffraction confirmed the formation of inverse spinel ferrite with face centered cubic structure and the dimensions of the NPs ranged from 9 to 17nm.
Abstract: In this study, nickel ferrite nanoparticles (NiFe2O4 NPs) were synthesized via simple and cost effective sonochemical method. X-ray diffraction confirmed the formation of inverse spinel ferrite with face centered cubic structure and the dimensions of the NPs ranged from 9 to 17 nm. Kubelka–Munk function was applied to study diffuse reflectance spectra and the band gap of the NPs was determined as 2.26 eV. Methylene blue (MB) and Drimarene yellow (DY) dyes were used as model dyes to study the photocatalytic properties of NPs under ultraviolet light irradiation. Point of zero charge (pHpzc) has played a significant role in understanding the adsorption of dyes onto the surface of the photocatalyst. Cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements for NiFe2O4 electrode were performed in 0.1 M HCl and 0.1 M NaOH aqueous electrolytes. The electrode exhibited specific capacitance of 2.084 F g–1 and 0.533 F g–1 in acidic and basic electrolytes, respectively. EIS measurements showed reduction in the charge transfer resistance. Modified carbon paste electrode using NiFe2O4 NPs has sensed Paracetamol in both acidic and alkaline electrolytes. These results indicated that NiFe2O4 is a promising electrode material for sensing paracetamol with high electrode reversibility and is an excellent photocatalyst. Hence, sonochemically synthesized NiFe2O4 NPs are expected to offer significant insight into their multifunctional applications.

TL;DR: In this article, an incompressible electrically conducting Casson-Maxwell fluid flow confined across two uniformly stretchable disks is reported, and the results of physical parameters are discussed by plotting the effects of such parameters on velocity, thermal and concentration fields.
Abstract: This study reports an incompressible electrically conducting Casson–Maxwell fluid flow confined across two uniformly stretchable disks. Buongiorno nanofluid model is implemented in the fluid flow. Cattaneo–Christov theory of double-diffusion is characterized through the heat and mass equations. Velocity, thermal and concentration slip conditions are executed at the lower stretchable disk. The flow model is dimensionalized through the similarity functions and then numerical solution is attained by RKF-45 scheme combined with shooting technique. The results of physical parameters are discussed by plotting the effects of such parameters on velocity, thermal and concentration fields. The results revealed that the Maxwell liquid is highly effected by Lorentz force than the Casson liquid. Thermal gradient of Maxwell liquid is highly influenced by stretching ratio parameter when compared to Casson fluid. Increase in Casson parameter and Deborah number declines the velocity gradient. Rise in the values of Brownian motion parameter declines the concentration gradient. Finally, the upsurge in thermal relaxation time parameter enhances the thermal gradient quickly in absence of thermal slip parameter.
