Summary: The main objective of this study is to investigate the heat and mass transfer in an Ag-H2O thin film flowing past a stretching sheet with thermal and velocity slips. Various variables including porosity, thermal radiation, thermophoresis, and Brownian motion are taken into account, and the impact of nanoparticle volume fraction is analyzed using a modified Buongiorno model. The results show that an increase in the mixed convection parameter enhances the temperature profile and reduces the velocity profile, while thermophoresis increases both temperature and concentration profiles. Moreover, higher volume fractions of nanoparticles lead to higher temperatures and lower velocities.

Summary: In this article, the flow of upper-convected Maxwell (UCM) viscoelastic fluid in a permeable medium is analyzed. The Cattaneo-Christov (CC) heat flux theory is used for heat transfer phenomena. Various factors such as thermal radiation, thermal slip condition, and magnetohydrodynamic (MHD) are considered in modeling the physical phenomena. The equations of fluid flow are transformed to non-linear ordinary differential equations (ODEs) and solved numerically with boundary conditions. Results show that velocity decreases with the magnetic parameter, temperature increases with thermal radiation and magnetic parameters, and Nusselt number behaves oppositely for different parameters.

Summary: Pure and doped ZnO nanoparticles were synthesized via a modified sol-gel method. The crystal structure of ZnO remained intact with vanadium doping, as confirmed by various analytical techniques. SEM and TEM were used to examine the morphology of the samples. UV-Vis-NIR spectra showed changes in the band gap and absorption band with increased vanadium content. Photoluminescence analysis revealed the creation of defects in the band gap due to vanadium doping. Magnetic studies indicated a mixed state of ferromagnetic and paramagnetic phases, with magnetic interaction explained by defects-induced magnetic polarons.

Summary: The present study investigates the characteristics of 2D MHD melting and its effect on mass and heat transportation in stagnation point Powell-Eyring nanofluid flow on an extensible surface. Melting is a vital phenomenon involved in various procedures, including permafrost melting, solidification of slag, and defrosting frozen ground. A mathematical model is developed to describe the boundary layer flow, and numerical algorithms implemented in MATLAB are used to solve the corresponding differential equations. The graphical representations of the numerical variations of embedded parameters provide insights into velocity, temperature, and concentration profiles, as well as the width of the boundary layer and its delineation rate with increasing velocity parameter. The velocity function exhibits a decremental response to M, while the concentration field shows the opposite behavior.

Summary: In this paper, numerical investigations were conducted to study the impact of double stratification with a radiative mixed convective nanofluid over a cylinder. The study focused on the heat transfer characteristics and mass transfer involving Brownian motion and thermophoresis inspiration. The equations were solved numerically using MATLAB, and graphical illustrations were provided for the distribution of velocity, energy, and concentration against different parameters. The results showed enhancement in concentration profile and a decrease in temperature field with varying thermophoresis and thermal stratification parameters. The agreement with previously published results was found to be good, and a higher Hartmann number indicated a higher coefficient of friction.

Summary: The most important condition for modern industrial activities is excellent refrigeration performance in conventional buildings. The Buongiorno relation assessment explores the thermal and mass efficiency of nanofluids, which has led to the identification of different properties related to random motion and thermophoretic diffusion. Non-Newtonian nanofluids have various applications, including thermal exchangers, solar liquid boilers, and heat control in vehicles. Nanoparticles can significantly improve the thermal conductivity and heat transfer properties of fluids, making nanofluids attractive for cooling systems in electronic devices and industrial applications where efficient heat transfer is crucial.

Summary: Bio-convection mechanisms have various uses, including in sedimentary pools, fuel models, and microbially accelerated oil restoration. This study examines the application of bio-convective nanoparticle fluid flow and electrically conducting incompressible magneto-hydrodynamic flow of nanofluid on a chemically reactive stretchable surface. The findings show that the magnetic field slows down fluid motion when thermal and mass buoyancy forces speed it up, and that thermophoretic diffusion increases the temperature and concentration of the fluids. The Brownian motion, concentration exponent, and chemical reaction parameters affect the temperature and concentration relationship. Additionally, the presence of a magnetic field and the first-order chemical reaction impact heat transfer rate and shear stress.

Summary: Cilia are commonly found in mammalian cells and play a significant role in cell cycle movement and proliferation, as well as human and animal growth. They can generate propulsive forces that enable the movement of organisms in fluid settings. In this study, thermal and mass transfer in beating cilia of non-Newtonian Ree-Eyring fluid were measured in two- and three-dimensional channels using magnetohydrodynamics in porous medium. The governing equations for both the dusty and fluid phase were formulated, and exact solutions for velocity, temperature, concentration, and pressure gradient were calculated. The physical behavior was discussed by plotting dimensionless parameters for velocity, thermal, and concentration.
