Proton exchange membrane fuel cells (PEMFCs) typically use Nafion®, which has many drawbacks, such as high cost, crossover, and strenuous synthesis processes. As such, an alternative Nafion®-ionomer free proton conductor drawn significant interest. Graphene oxide (GOM) is a promising due to its hydrophilic nature attractive conductivity under humidified conditions. However, pristine GOMs have i...

Selective Proton Transport In article number 2215109, Tongwen Xu, Liang Ge, Xingya Li, and co-workers report a series of dibenzo-18-crown-6 functionalized sulfonated poly(biphenyl alkylene) membranes. The membranes possess synergistic hydrophilic networks induced by bi-functional sites (crown ether sulfonic-acid group), increasing selective proton transport, providing efficient acid recovery in...

In this work, the impact of lipid lateral mobility on the steric interaction between membranes containing poly(ethylene glycol) (PEG) functionalized lipids was investigated using the surface force apparatus. The force-distance profiles show the presence of electrostatic and steric repulsion that arise from the presence of negatively charged PEG functionalized lipids. Fluid-phase bilayers have h...

Membranes made up of composite materials have shown promising advantages for application in alkaline fuel cell anion exchange membranes. In this study, a general method is employed to improve the overall performance and properties membranes by making use polyethersulfone quaternized with imidazolium groups blended functionalized graphene oxide inorganic filler (ImGO). The polymer matrix yielded...

Ceramic hollow-fibre membranes which have an asymmetric structure have been prepared in one step, using an immersion induced phase inversion technique. With this method, membranes with a high surface area per unit volume ratio can be produced, while production cost is dramatically reduced. Yttria-stabilised zirconia (YSZ) is selected as a membrane material, as it is relatively inexpensive and h...

abstract— in the present study, genetic programming (gp) as a completely different approach in comparison with conventional methods, based on the imitation of natural evolution of living organism is proposed for the prediction of cellulose acetate (ca) polymeric membrane characteristics. the membrane preparation parameters of polymer concentration, additive concentration and coagulation bath te...
