In this work, the porous ceramic multilayer ultrafiltration membrane is developed. Macroporous support was formed by extrusion of paste derived from natural Moroccan Sahara Clay. The microporous interlayer then performed slip casting zirconia commercial powders and finally active toplayer obtained solgel route using TiO 2 sol. performance evaluated pores diameter, thickness top layer, water flu...

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...

Microporous poly(vinylidene fluoride) (PVDF) membranes were prepared from PVDF/N,N-dimethylacetamide (DMAC) solutions by using upercritical CO2 phase inversion process. As revealed by scanning electron microscope (SEM) and differential scanning calorimeter (DSC), he PVDF membranes exhibit morphological characteristics resulting from both liquid–liquid phase separation and crystallization, i.e.,...

Graphitic carbon nitride (g-C3N4) with photo-attached platinum (Pt@g-C3N4) is known to generate hydrogen under illumination in aqueous environments the presence of carbohydrate hole quenchers. Here, Pt@g-C3N4 embedded into a polymer intrinsic microporosity (PIM-1) host material molecularly rigid structure maintain active unblocked catalyst surfaces and control transport to/from photocatalyst. A...

Biorelevant dissolution is an indispensable tool utilized during formulation development and optimization for the prediction of in vivo bioavailability of pharmaceutical agents. Within that framework, membrane-permeation dissolution methodologies are widely used to model drug absorption. The current work evaluates polymer membrane surface modifications for production of biomimetic membranes to ...
