Abstract:
A sorbent polymer is provided that interacts or reacts with aqueous urea to aid the regeneration of a dialysate liquid. The sorbent polymer may include one or more specific functional groups bonded thereto. Such specific functional groups are selected from carboxylic acids, carboxylic acid esters, carboxylates, amides, dicarboxylic acids, dicarboxylic acid esters, and dicer boxylates to produce the desired urea sorbent.
Abstract:
In a method of regenerating a carbon slurry (14) used to produce a black matrix-type phosphor screen of a cathode ray tube, excess carbon slurry is collected (21) after the completion of carbon-coating of a cathode ray tube panel (11) and the collected carbon slurry is regenerated by means of an ion-exchange resin. The method can be employed in an apparatus for producing the screen, the apparatus including a nozzle (17) for coating the slurry (14) on the panel (11), a tank (13) containing the slurry, a supplying system (16) for supplying the slurry from the tank to the nozzle, a collecting system (21) for collecting the excess slurry produced from the nozzle back into the tank, and a carbon slurry regenerating device (24) using the ion-exchange resin. The regenerating device (29) can be placed in at least one of the supplying system (16), the collecting system (21) and the tank (13).
Abstract:
Steam generating systems (20) in which steam and water wetted components are fabricated from corrosion resistant materials. This reduces the requirement for chemical feedwater treatment to removal of dissolved solids from the feedwater. Ion exchange resins (98) are employed for this purpose to remove contaminants from both condensate and make-up water. Feedwater treatment is completed by filtering suspended solids from the condensate and make-up water and by utilizing hot well (64) deaeration as necessary to reduce the dissolved gases content of the feedwater to an acceptable level.
Abstract:
The present invention is directed to lithium ion transport media for use in separators in lithium ion batteries, and the membranes, separators, and devices derived therefrom.
Abstract:
The present disclosure provides a membrane having a first major surface and a second major surface and including one or more anionic exchange electrolyte polymers. The membranes can be useful for selectively mass transporting molecules and/or ions.
Abstract:
In a method for making anion electrolyte membrane a fluorinated poly(aryl ether) ionomer is dissolved in a solvent to form a ionomer solution. A crosslink component is added to the ionomer solution, to achieve a transparent solution. An inorganic component precursor and water are introduced to the transparent solution, to form a sol-gel mixture. A crosslink catalyst is mixed with the sol-gel mixture to form a membrane casting solution. The membrane casting solution is coated on a substrate to form a membrane, and heated. The membrane is removed from the substrate.
