Abstract: A barrier coating composition includes a polymer material and a structuring agent dispersed in said polymer material, wherein the structuring agent decreases oxygen or water permeability through the polymer material. The barrier coating composition can be used to coat a core component, which can be oxygen or water sensitive, to form a microencapsulated material. The microencapsulated material can be formed by microencapsulation methods, which include atomization or coacervation methods, including forming an oil emulsion of an oil phase and an aqueous phase, the oil phase including the core component and the aqueous phase including the polymer material, adding the structuring agent to one of the oil phase and the aqueous phase, mixing the oil emulsion to form desired particle sizes of the core component, forming the shell component around the core component to form the microencapsulated material, and extracting the formed microencapsulated material from the oil emulsion.

Abstract: The invention relates to pumpable heat transfer compositions wherein a solid polymeric porous structure having absorbed therein a polar or non-polar phase change material is incorporated with a heat transfer carrier liquid, with the phase change material being present in an amount sufficient to increase the heat capacity and/or heat transfer coefficient of the carrier liquid. The invention also relates to the method of increasing the heat capacity and/or heat transfer coefficient of a heat transfer carrier liquid by adding thereto a solid polymeric porous structure having absorbed therein a polar or non-polar phase change material.

Abstract: An active material encapsulated in a coating material immiscible therewith is contacted with a solvent that dissolves residual active material on the surface of the coating material without dissolving the coating material. The resultant encapsulated material has improved stability as compared to the material not contacted with solvent.

Abstract: Osteoprogenitor cells encapsulated in alginate and alternatively, additionally encapsulated in poly-L-lysine and/or agarose promote regeneration of bone at the site of implantation. The present invention provides a composition comprising osteoprogenitor cells embedded or encapsulated in alginate and the use of said microcapsules for the facilitation of bone regeneration.

Abstract: A process for preparing fatty acid microspheres of microorganisms by rotary disc processing is disclosed. The process is designed to minimize heat risk to the microorganisms during production. Microsphere particles of fatty acid matrix containing microorganisms, preferably stearic acid encapsulated Enterococcus faecium, are also provided.

Abstract: A biodegradable composition comprising a polymer matrix having distributed substantially uniformly therethrough hollow sphere-like inclusions or microcapsules, said polymer matrix consisting essentially of a water-soluble polymer/polymer-compatible salt complex with said salt present in an amount sufficient to render said polymer insoluble in water and products made by shaping such composition.

Abstract: The invention is a process for preparing round, fluid filled microcapsules by the simultaneous extrusion, of core and shell material from coaxially aligned and concentric extrusion nozzles into a surrounding carrier fluid moving in the direction of the extrusion wherein a surfactant having affinity with the carrier fluid is added to the carrier fluid.When the carrier fluid is an oil based carrier, a lipophilic emulsifier such as a sorbitan monoester of a fatty acid can be used.

Abstract: A method of manufacture and the product made thereby are set forth; in the preferred and illustrated embodiment, a core including an insect poison is encapsulated by shell material melting and hardening for encapsulation. The core is primarily soybean extract mixed with DURSBAN.RTM. insecticide, an example of a toxicant. The surrounding shell or encapsulation is formed by melt extrusion of shell material. The surrounding shell encloses the core material to form an impervious shell. The surrounding shell includes soy protein as an insect attractant mixed in gelatin or poly(vinyl alcohol). A gelling agent such as carrageenan and the attractant were added to the shell. The beads formed by the melt extrusion encapsulation has sufficient shell strength to enable mechanical handling for dispensing, are resistant to water, do not bleed from the inside to the outside, and yet can be penetrated by the insect.
