Abstract: The present disclosure provides an ethylene oxide sterilization sensor and method of use. The sensor includes: at least one thermal indicator component independently selected from an electronic thermal sensor, an irreversible temperature indicator, and a heat-shrinkable film; an acid-functional porous sorbent or an acid-functional nonwoven fibrous substrate in thermal contact with the at least one thermal indicator component; and an acid having a boiling point above 120° C. and a pKa of no greater than 2.5. The acid is impregnated in or covalently attached to the porous sorbent or is covalently attached to the nonwoven fibrous substrate. The sensor includes at least one of the electronic thermal sensor, the irreversible temperature indicator, or the acid-functional nonwoven fibrous substrate.

Abstract: A sorbent suitable for sorbing aldehydes includes acidified zeolite impregnated with a urea-based compound, the acidified zeolite having a pore opening of 5 Å or greater and a molar ratio of silicate to aluminate of at least 1.1:1. The sorbent may be prepared by impregnating acidified zeolite with a solution of a urea-based compound, where the acidified zeolite includes proton counterions. The sorbent may be supported on a filter support to provide an air filter.

Abstract: Polymeric sorbents for aldehydes including formaldehyde are provided. More particularly, the polymeric sorbents are a reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. The nitrogen-containing compound is covalently attached to the resulting polymeric sorbent. Additionally, methods of sorbing aldehydes (i.e., aldehydes that are volatile under use conditions) on the polymeric sorbents and compositions resulting from the sorption of aldehydes on the polymeric sorbents are provided. The polymeric sorbents typically are porous with the pores often being in the size range of mesopores and/or micropores.

Abstract: Compositions are provided that include a matrix and a polymeric composite particles disposed in the matrix. The polymeric composite particles include a porous polymeric core and a fragrance positioned within the porous polymeric core. Polymeric composite particles are also provided including a porous polymeric core, a fragrance positioned within the porous polymeric core, and a coating layer around the porous polymeric core. Further, a method of determining a minimum temperature of a composition is provided including providing a composition including polymeric composite particles disposed in a matrix, heating the composition, releasing at least a portion of the fragrance as a vapor from the porous polymeric core of the polymeric composite particles at or above the minimum temperature, and detecting at least a portion of the fragrance vapor in a location outside of the matrix.

Abstract: Hydrolyzed divinylbenzene/maleic anhydride polymeric materials and methods of making these polymeric materials are provided. These polymers have a high BET specific surface area that results from the presence of micropores and/or mesopores. The polymers are useful for the adsorption of low molecular weight (e.g., no greater than 150 gram/mole), basic nitrogen-containing compounds.

Abstract: Composite granules that contain a binder and a polymeric sorbent material for capturing aldehydes such as formaldehyde are provided. Additionally, methods of making the composite granules, methods of using the composite granules to capture aldehydes, and compositions formed by reacting the composite granules with aldehydes are provided. The polymeric sorbent material included in the composite granules is a reaction product of a divinylbenzene/maleic anhydride precursor polymeric material with a nitrogen-containing compound. This reaction results in the formation of nitrogen-containing groups that are covalently attached to the polymeric sorbent. Aldehydes can react with the nitrogen-containing groups.
