The reliance on imported bentonite for drilling fluid formulation in Nigeria poses significant economic challenges and limits local content development. This study evaluates the suitability of indigenous clay deposits from the Egbeta community, Edo State, for water-based drilling fluid applications. Clay samples were collected and subjected to laboratory analyses,... Continue here

This study presents a Hankel-transform-based analytical framework for optimising electromagnetohy-drodynamic (EMHD) fluid flow over a cylindrical surface, motivated by advanced material-processing applications such as coating, extrusion, thermal treatment, and surface modification. The interaction between electromagnetic forces and conductive fluid motion in... Continue here

This study employs spin-polarised density functional theory (GGA PBE+U) to investigate the structural, electronic, and magnetic properties of Fe-substituted Cu₂O at a nominal dopant concentration of 2.08%, corresponding to one Fe atom in a 2×2×2 supercell (48 atoms). The optimised lattice constant of pristine Cu₂O (4.252 Å) agrees closely with... Continue here

The present study investigates the electromagnetohydrodynamic (EMHD) boundary-layer flow, heat transfer, and mass transport of an electrically conducting viscous fluid over an exponentially stretching cylindrical surface with applications in advanced material processing systems. The mathematical model incorporates the combined effects of thermal radiation,... Continue here
