Abstract: An electrophoretic gel comprising at least one crosslinked temperature-responsive polymeric compound having an LCST is disclosed. A method of separating and recovering substances involves conducting the electrophoresis of a sample containing substances to be separated using the electrophoretic gel at a temperature below the LCST, excising each portion of the gel containing the substance to be separated and raising the temperature of the excised portion to a temperature above the LCST to shrink the excised portion to recover the substances.

Abstract: A coating of resin and photoactive functionality is autodeposited from an emulsion onto a metallic substrate in order to selectively protect the substrate from corrosive environments such as etchant processes. An acid and oxidizing agent are included in the emulsion so that when the substrate is immersed in the emulsion the resin and photoactive functionality autodeposits. The resulting coating can be exposed to actinic radiation in an image-wise fashion and developed in an alkaline solution to develop the image created. In instances where the emulsion and process are used to make circuit boards, the metallic surface uncovered during developing is then etched away, leaving only the coated sections of the surface. The resulting coated surfaces will be the circuit traces of the circuit board.

Abstract: A method of preparing a hydrophilic, biocompatible contact lens characterized by a surface which resists nonspecific protein adsorption. The method involves forming a prepolymer, at least 75% of which are oxyethylene-based diols and polyols having molecular weights of about 7000 to about 30,000. The prepolymer is subsequently gelled and hydrated to produce a hydrated polyurea-polyurethane polymer gel. The hydrated polymer gel is used to obtain a contact lens which resists nonspecific protein adsorption. Preferably, the contact lens are prepared by molding the prepolymer into a contact lens mold, prior to polymerization, to achieve the desired lens shape.

Abstract: A process of inhibiting enzymatic browning in raw fruit and vegetable juices comprising treating the juices with cyclodextrins, individually or in combination. Soluble cyclodextrins treatments may be added directly to the juices. In the alternative, isoluble cyclodextrins may be used as a packing in a column or in a batch treatment process. In effect, treatments of the invention tend to limit the extent or rate of enzymatic browning in the affected juices. Also disclosed are novel browning inhibiting compositions which are effective in controlling enzymatic browning in raw fruit and vegetable juices. The novel compositions are potential alternatives for presently used sulfites.
