The viscoelastic properties of worm-like micelles formed by mixing the cationic surfactant N-hexadecyl-N-methylpiperidinium bromide (C16MDB) with the anionic surfactant sodium laurate (SL) in aqueous solutions were investigated using rheological measurements. The effects of sodium laurate and temperature on the worm-like micelles and the mechanism of the observed shear thinning phenomenon and p...

The classical viscous theory is limited to illustrating the characteristics of several materials like pseudoplastic and dilatant fluids. Sutterby fluid has features shear thinning thickening fluids because its Power law index. Therefore, this study considered an incompressible, time-independent electrically conducting flow across a rotating stretchable disk. disk experiences effect porous space...

Abstract A novel polymer nanocomposite has been synthesized in the present study using a bio-polymer Karaya and inorganic SiO 2 nanoparticles via sonication for application as fracturing fluid stimulating oil gas wells. Gum (KG), an acidic polysaccharide, investigated its structural, morphological rheological characteristics, results have compared with prepared KG–SiO at different dosing improv...

ultrasound-assisted extraction was used to determine the optimum processing conditions and to achieve the maximum extraction yield and viscosity of the gum extracted from quince seed. using response surface methodology (rsm) to design the experiments and adopting the central composite rotatable design (ccrd), the effect of extraction temperature (25-55°c), time (3-10 minutes), and ph (6-8) were...
