Summary: This study discusses the impact of unsteady magnetohydrodynamics hybrid ferrofluid flow over a stretching/shrinking rotating disc. By transforming the mathematical model into ordinary differential equations and analyzing the solutions, it is found that both solutions are stable. The research also reveals that the unsteadiness parameter decreases the boundary layer thickness of velocity and temperature distribution, while the magnetic and mass flux parameters have a lowering effect on the skin friction coefficient and the unsteadiness parameter has a supportive effect on the heat transfer rate.

Summary: In this investigation, three different frameworks of liquid-liquid extraction (L.L.E) were examined for determining slip velocity (S.V) and characteristic velocity (C.V) in a non-center rotating column (N.C.R.C) with a wide range of factors. Experimental tests were conducted using three dual systems with different interfacial tensions: toluene-water (high), n-butyl acetate-water (medium), and n-butanol-water (low). Two common relationships were proposed for predicting S.V and C.V, involving phase flow rates, rotor speed, column geometry, and physical properties. The proposed relationships were found to be more accurate than those previously reported.

Summary: The forced convection of power law fluid in a microchannel was studied using the Lattice Boltzmann method, considering viscous dissipation and wall slip condition. The effects of Reynolds number, Prandtl number, and slip coefficients were investigated. The study presented contour plots of velocity, temperature profile, local friction factor, and average Nusselt number. It was observed that the average Nusselt number was higher for shear-thinning fluid (n<1) compared to Newtonian fluid (n=1) and shear-thickening fluid (n>1). For Re=30, increasing the slip coefficient resulted in higher average Nusselt number. The results also showed that the friction factor decreased along the channel due to changes in velocity gradient. Slip coefficient improved the convection heat transfer mechanism for Non-Newtonian fluids.

Summary: This study analyzed the effects of rarefaction on permeability and heat transfer coefficients in convective gas flows by conducting pore-level analysis of a Kelvin cell model. The results showed that rarefaction significantly enhanced permeability, but this enhancement decreased with increasing porosity. Rarefaction also weakened inertial effects and drag forces, with a more pronounced effect at high Reynolds numbers. For highly conductive metal foam structures, the influences of boundary slip and temperature jump canceled each other out, resulting in Nusselt numbers primarily being dependent on Reynolds number.

Summary: This study examines the three-dimensional stretched flow of carbon nanotubes with variable thickness. The results demonstrate that an increase in the wall thickness parameter suppresses the magnitude of the surface drag force, while an increase in the nanoparticles volume fraction intensifies it. Additionally, the flow is enhanced by an increase in the shape parameter and nanoparticles volume fraction. Furthermore, an increase in thermal relaxation time leads to higher temperatures.

Summary: In this study, the magnetohydrodynamic bioconvective flow of a non-Newtonian nanomaterial over a stretched sheet is analyzed. The convective conditions and irreversibility analysis in the presence of gyrotactic micro-organisms are discussed. Energy expressions considering thermal radiation, heat generation, and ohmic heating are used. By employing Buongiorno's model, the characteristics of the nanoliquid through thermophoresis and random diffusions are studied. Nonlinear expressions of the model are transformed through adequate transformations and computed using the Newton built in-shooting technique. Graphical studies are conducted on influential variables for velocity, concentration, microorganism field, temperature, and entropy rate. Significant findings include velocity reduction with bioconvection Rayleigh number and magnetic variable, temperature augmentation with higher heat generation variable, and entropy and temperature enhancement with increased magnetic variable.

Summary: This study investigates the thermodynamic quantities, such as entropy, specific heat, and magnetic susceptibility, in the next-nearest-neighbors Heisenberg model on a honeycomb-kagome lattice. The linear spin-wave approach is applied to obtain the temperature-dependent behavior of these quantities. Additionally, the entanglement negativity, a quantifier of quantum entanglement, and the spin Hall conductivity are also studied. The results show that all the thermodynamic quantities, as well as the entanglement negativity and spin Hall conductivity, exhibit an increasing trend with temperature. Furthermore, it is found that all the analyzed quantities approach zero in the low-temperature limit, consistent with experimental observations.
