Studies on crystal semi-permeable membrane. II. On the formation of barium sulfate semi-permeable membrane.
The 1st report1) in a series of these studies, which was deduced from the report by Miyamoto and Takikawa2) that a precipitate of calcium silicate and magnesium silicate formed a semi-permeable membrane at the Pringsheim'a equilibrium point, recognized a formation of the so-called •hCrystal semi-permeable membrane•h also in a common water-insoluble salt (In this case, sodium carbonate and calci...

present for the formation mechanism. A famous •gPfeffer's semi-permeable membrane•h made of potassium ferrocyanide and copper sulfate in unglazed pottery cylinder by W. Pfeffer in 1877 is quite different from an artificial semi-permeable membrane at present, which is organized only by handling of extending high molecular substances, that is, collodium, cellophane, and various synthetic resins. ...
متن کاملGrowing Vegetable Seeds for Sale
MEN WHO grow vegetable seeds for sale engage in a specialized and highly competitive farming operation. They compete to maintain superior strains of most standard varieties and to develop new varieties. Most of the large vegetable seed companies have well-qualified staffs to develop and maintain stock seed, from which is produced seed for the market, mostly by farmers who have contracts with th...
متن کاملElectrostatic interaction of neutral semi-permeable membranes.
We consider an osmotic equilibrium between bulk solutions of polyelectrolyte bounded by semi-permeable membranes and separated by a thin film of salt-free liquid. Although the membranes are neutral, the counter-ions of the polyelectrolyte molecules permeate into the gap and lead to a steric charge separation. This gives rise to a distance-dependent membrane potential, which translates into a re...
متن کاملA New Approach to Provide High Water Permeable Polyethersulfone based Nanofiltration Membrane by Air Plasma Treatment
In this study, polyethersulfone based nanofiltration membranes were modified by air plasma generated through dielectric barrier discharge to increase the membrane hydrophilicity aiming to improve the separation and antifouling characteristics. The effect of plasma time on the physico-chemical and separation properties of membrane was investigated. The PES nanofiltration membranes were fabricate...
