Inorganic-organic composite electrolyte membranes were fabricated from CsXH3-XPMo12O40 (CsPOMo) and quaternary diazabicyclo-octane polysulfone (QDPSU) using a polytetrafluoroethylene (PTFE) porous matrix for the application of intermediate temperature fuel cells. The CsPOMo/QDPSU/PTFE composite membrane was made proton conducting by using a relatively low phosphoric acid loading, which benefits...

Membrane-based separation has gained increased popularity over the past few decades, particularly reverse osmosis (RO). A major impediment to improved performance of membrane processes, in general, is fouling. Fouling detrimental effects on membrane’s and integrity, as deposition accumulation foulants its surface and/or within pores leads a decline permeate flux, deterioration selectivity, perm...

Mismanagement, pollution and excessive use have depleted the world’s water resources, producing a shortage that in some territories is extreme. In this context, need for potable prompts development of new more efficient wastewater treatment systems to overcome shortages by recovering reusing contaminated water. Among methods, membrane technology considered one most promising. Besides, photocata...

Fouling and scaling in membrane distillation (MD) is one of the significant barriers to its continued growth. Fouling in MD blocks the pores, causing a decline in permeate flux, and may eventually lead to wetting of a hydrophobic membrane by the saline feed, contaminating the permeate. Many previous studies on MD have observed that while MD is more fouling resistant than reverse osmosis (RO), i...

In electroosmotic dehumidification, a membrane composed of a desiccant material removes moisture from air to be conditioned. Then, electroosmotic pumping driven by the application of voltage moves the moisture across the membrane and rejects it on the other side. A bench top experiment was developed to screen promising membrane materials. Two sealed humidity chambers were separated by a membran...

Stimulation of Mg(2+)-dependent inorganic pyrophosphatase activity several fold by disruption of mitochondrial membranes does not appreciably alter the catalytic properties of the enzyme. Stimulation is due to increased accessibility of substrate to the enzyme, which is not solublized on activation. The enzyme is attached to the inside of the inner membrane, and under physiological conditions p...
