The all-iron flow battery is currently being developed for grid scale energy storage. As with all batteries, the membrane in these systems must meet stringent demands ionic conductivity while limiting unwanted reactant (Fe 3+ ) crossover. In addition, chemistry proton transport across highly desirable to maintain pH levels negative and positive electrolytes. Two membranes are considered, Nafion...

Recovery of ammonia (NH3) from residual waters offers various reuse opportunities, such as the production fertilisers and generation electricity heat. However, simultaneous evaporation water (H2O) during NH3 stripping under vacuum results in diluted recovered gas with high H2O contents. Whereas porous gas-permeable membranes are already used for stripping, use non-porous silica-based pervaporat...

proton exchange membrane fuel cells (pemfcs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. in this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/la2ce2o7 (pva-lc) with the aim of increasing the water uptake and proton conductivity. glutaraldehyde (ga) was used as cross linking agent ...

Membrane structuration of Large Hybrid Unilamellar Polymer/Lipid Vesicle (LHUV) is an important parameter on the optimization their properties and thus valuation in various fields. However, this kind information hardly accessible. In work, we will focus development LHUV obtained from self-assembly diblock poly(dimethylsiloxane)-b-poly(ethylene oxide) (PDMS-b-PEO) different molar masses combined...
