Phosphoric acid doped ABPBI (poly [2,5-benzimidazole]) membranes were prepared with a new low temperature casting procedure (ABPBI-ET), and their water uptake and proton conductivity were measured. The results were compared ...

New bacterial cellulose (BC)-triethanolamine (TEA) ion-conducting membranes have been prepared and characterized. The samples were obtained by soaking BC membranes in triethanolamine aqueous solutions and drying. The ...

Mixed ion/electron conductive ceramic materials, like perovskite, have recently gained relevance due to their possible applications in membrane technology. This work describes the preparation and characterization of a mixed ...

The role of different gossypol tautomers in the interaction of this molecule with membranes has been investigated using the isolated hemiacetal moiety of gossypol and the pH dependency of the keto-enol tautomeric equilibrium. ...

This work reports results from impedance spectroscopy, nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR) of chitosan bio-membranes, containing acetic acid and either with or without glycerol. Ionic ...

In this work, the proper charge density of a microfiltration membrane has been determined by using two different methods. Firstly, the ionic transport of a KCl solution has been investigated by simultaneous measurements ...

Nanocomposite polymer membranes based on PVA/TiO2 were prepared by a solution casting method. Glutaraldehyde solution (GA) was used as linking agent to improve the chemical, thermal and physical properties of the membranes. ...
