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: 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: The present disclosure provides an ammonia 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 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. The method includes: placing an ammonia sensor in contact with a container holding a volume of ammonia; and monitoring the ammonia sensor for a detectable response from the at least one thermal indicator component due to contact of ammonia with the acid that generates thermal energy sufficient to cause the response.

Abstract: The present disclosure provides a hydrogen peroxide 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; a reactant-functional porous sorbent in thermal contact (which may or may not be direct physical contact) with the at least one thermal indicator component; and a reactant comprising a material that reacts exothermically with hydrogen peroxide. The reactant is impregnated in the porous sorbent. The method includes: providing a hydrogen peroxide sterilization sensor; allowing hydrogen peroxide to contact the reactant to generate thermal energy sufficient to cause a response from the at least one thermal indicator component; and detecting that conditions for the hydrogen peroxide sterilization have been met.
