Evaluating the Impact of Cellulose Nanocrystals on the Performance of Polycarbonate Thin‐Film Nanocomposite Membranes for Treating Oily Wastewater

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...

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

Asia-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.
