Abstract:
The present invention relates to methods of separating one or more components from a feed composition, methods of desorbing one or more components from an absorbent fluid, as well as systems and apparatus that can carry out the methods. In one embodiment, the present invention provides a method of separating one or more components from a feed composition including contacting at least some of a first component of a feed composition including the first component with an absorbent fluid, to provide a contacted composition and a used absorbent fluid including at least some of the first component contacted with the absorbent fluid. In some embodiments the absorbent fluid can be an organosilicon fluid including an organosilicon including at least one of a hydroxy group, an ether group, an acrylate group, a methacrylate group, an acrylamide group, a methacrylamide group, and a polyether group. In some embodiments, during the contacting the feed composition can be contacted to a first side of a membrane while the absorbent fluid is contacted to a second side of the membrane. In some embodiments, the membrane can be a silicone membrane.
Abstract:
Provided in various embodiments are addition curable silicone compositions, methods for their preparation, and uses thereof for delivery of personal care and healthcare active ingredients, and agricultural active ingredients. In some embodiments, such addition curable silicone compositions comprise an addition curable organopolysiloxane, a hydrosilylation cure catalyst or initiator for the addition curing reaction, (c) a hydrogel or hydrogel microparticle whose surface has been modified by an organopolysiloxane or silane through either an amine-capping reaction or through a free radical-initiated encapsulation process utilizing an organoborane initiator. The silicone compositions optionally comprise or are optionally treated with one or more of at least one multifunctional crosslinker for the addition curable organopolysiloxane, at least one water-soluble active ingredient, and at least one surfactant. The hydrogel or hydrogel microparticle includes at least one siloxane-coated surface. The silicone compositions are hydrosilylation curable silicone compositions.

Various embodiments disclosed relate to systems and methods for dehumidifying or humidifying air, and methods of using the same. In various embodiments, the present invention can provide an HVAC system including a radiant heat transfer device in fluid communication with a membrane module or a liquid contacting device. The membrane module or liquid contacting device can enrich or deplete water in a feed gas mixture including air.
Abstract:
The present invention relates to hollow fibers. In some embodiments, the present invention provides a method of forming a hollow fiber. The method can include providing or obtaining a solid core including a core composition that includes about 50 wt% to about 100 wt% of a composition that is at least one of meltable and sublimable. The method can include coating the core with a curable composition. The method can include curing the curable composition. The method can include melting or subliming at least part of the core composition, to provide a hollow fiber. In some examples, the hollow fiber can be an organopolysiloxane hollow fiber. In various embodiments, the present invention provides a hollow fiber made by the method, an organopolysiloxane-coated core, or a core coated with a cured organopolysiloxane composition.
