The Alexandria University process uses pervaporation--separating components of a mixture by passing it through a semipermeable membrane
and evaporating the liquid--eliminating the need for electricity to pump water by relying on the sun and natural processes of evaporation.
The research on IEMs began in 1890 when Ostwald  discovered that a semipermeable membrane
could be impermeable for any electrolyte if it was impermeable either for its cation or its anion and postulated the existence of the so-called "membrane potential" at the boundary between the membrane and the solution caused by the difference in concentration.
A two-fluid flat plate LAMEE is composed of several parallel air and desiccant solution channels, where each adjacent air and solution channels are separated by a semipermeable membrane
Round window membrane is the only soft tissue barrier separating the middle ear from the inner ear this semipermeable membrane
appears to be the main portal for the passage of noxious substance from the middle ear cavity to the labyrinth.
Gareau, is that the gut is bounded by a semipermeable membrane
containing hundreds of millions of microbes.
Osmotic systems consist of a hydrophilic matrix and a coated extended-release system, with polyethylene oxide polymers and inorganic salts or sugars as osmogens in the tablet core and cellulose acetate with polyethylene glycol (PEG) polymers as the semipermeable membrane
Obesity and overconsumption of foods high in saturated fats and simple carbohydrates have been found to weaken the blood brain barrier (BBB), a semipermeable membrane
that helps protect the central nervous system and brain from pathogens and toxins circulating in the bloodstream.
Avoid slow-release formulations, including ion-exchange resins with a semipermeable membrane
and those with slowly dissolving characteristics; substitute an immediate-release formulation.
When two solutions with different salt concentrations come into contact through a semipermeable membrane
, these solutions 'want' to mix so that the concentration of salt is the same on both sides of the membrane--a natural process called osmosis.
In addition to the danger of direct intravenous bacterial inoculation, the small molecular size of endotoxin and endotoxin fragments produced by bacteria enables them to pass through the semipermeable membrane
of a dialyzer from the dialysate compartment.
In nanofiltration (NF), a pressure driven membrane separation process, the separation takes place across a semipermeable membrane
Replace the anode, cathode, and semipermeable membrane
in each electrolytic cell annually.
