Performance of polyacrylamide and poly(acrylamide/sodium acrylate) hydrogel-coated mesh for separation of oil/water mixtures
(Elsevier, 2018-12-01)Hydrogels are widely used as a coagulant in water treatment in addition to using in tissue engineering due to their high water absorption capacity and biocompatibility. Our research objective is to synthesize a reinforced ... -
Controlling the sustainability and shape change of the zinc anode in rechargeable aqueous Zn/LiMn2O4 battery
(Elsevier, 2018-11-01)The use of thixotropic gel electrolytes in the rechargeable hybrid aqueous battery improves the battery performance but it is required to have a corrosion inhibitor in the gel electrolyte. These inhibitors are not always ... -
Measuring effective diffusivity in porous media with a gasket-free, radial arrangement
(Elsevier, 2019-02-01)A simple technique for measuring the effective diffusivity, and ultimately tortuosity, in porous media is presented. The method uses a custom-built apparatus, based on a radial geometry, which eliminates the need for any ... -
Optimization and control of a thin film growth process: A hybrid first principles/artificial neural network based multiscale modelling approach
