Transport studies of ions across polystyrene based composite membrane: Evaluation of fixed charge density using theoretical models

The fabrication of a highly conductive ceria-embedded gadolinium-stabilized bismuth oxide nanocomposite solid electrolyte for low-temperature solid oxide fuel cells

“…A further decrease in the TGA curve indicates weight loss of 2% from the nanocomposite material, which is attributed to the removal of lattice water in the temperature range of 300-480 1C. 36 As shown in the plot, the sample is stable from 500 1C to 800 1C, as revealed by the small weight loss from the nanocomposite. A strong endothermic peak is observed at 700-750 1C in the DTA curve, which shows a Bi 2 O 3 phase transformation from the a phase to the d phase.…”

Transport and surface charge density of univalent ion of polyvinyl chloride-based barium tungstate ion-exchange composite membrane for industrial separation of waste water

“…For this purpose, a variety of ion exchange membranes such as organic, inorganic and composite membranes have been used [11–16]. However, inorganic material plasticizes in an organic polymer such as polyvinyl chloride (PVC) in the form of the composite are very stable at high temperature as well as in acidic and basic media [17–20]. PVC is stable in all acid /base and all inorganic chemicals [21].…”
