Impact of Cattaneo–Christov Heat and Mass Flux on MHD Hybrid Nanofluid Flow Over an Extending Surface With Convective and Mass Flux Effects

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study investigates the flow of a magnetized hybrid nanofluid over a permeable stretching surface. The mass and thermal transport within the system is regulated using the Cattaneo–Christov flux theory. The fluid is additionally subjected to thermophoresis, chemical reaction, Brownian motion, and activation energy effects.

USING CHARACTERIZATION AND SYNTHESIS OF FATLIQUOR FROM SUDANESE CASTOR OIL

open access: yes, 2017
<p>Castor oil is classed as semi-drying oil because it oxidizes on exposure to air, giving a gummy film, and can be highly sulphated to make it miscible in water.
