In this study, a chemical additive made by a combination of polymer, alkaline, and silica nanoparticles is used to control the oil recovery and relative permeability curves. Various parametersincluding the type and concentration of polymer, alkaline, and nanosilica particles have been studied.To evaluate the efficiency of these additives, we performed unsteady state displaceme...

Breast cancer is one of the most common diseases modern age. Although many methods for its treatment have been reported so far, report and synthesis new compounds based on technologies, especially nanotechnology, important. One laboratory evaluating anticancer properties in vitro MTT method (3-(4,5-Dimethylthiazol-2-yl)-2,5-Diphenyltetrazolium Bromide). In this study, anti-breast activity newly...

Background & Aims: Magnetically molecularly imprinted polymers (MMIPs) are assumed as kind of sorbent polymers ‎which can separate or determine bioactive compounds from environment fast and specifically.  ‎Magnetic properties, stability at various conditions (temperature , ionic strength and pH) and selective ‎function are among the advantages of these polymers in determin...

This study presents an innovative method for creating a highly porous surface with nanoscale roughness on biologically relevant polymers, specifically polyurethane (PU) and polycaprolactone (PCL). Nanoembossed polyurethane (NPU) and nanoembossed polycaprolactone (NPCL) were produced by the casting of PU and PCL over a plasma-deposited, spiky nanofeatured crystalline titanium (Ti) surface. The v...

Abstract The effects of a chemical reaction and radiative heat flux in nonlinear mixed thermo-solutal convection flow viscoelastic nanoliquid from stretchable surface are investigated theoretically. Newtonian heating is also considered. upper-convected Maxwell (UCM) model deployed to represent the non-Newtonian characteristics. includes influence thermal radiation that simulated via an algebrai...
