Abstract: A method of forming a porous structure involves mixing a solvent with a curable material which disperses in the solvent such that the mixture has greater than 50% solvent content. The mixture is deposited on a substrate and viscosity of the mixture is increased. The curable material in the mixture is cured while a shape of the curable material is maintained by the solvent. After curing, the solvent is removed from the structure.

Abstract: An electrochemical device suited to modifying a carbon dioxide concentration in an interior space includes a cathode chamber with an inlet which receives a feed gas containing carbon dioxide. A reduction catalyst layer in the cathode chamber reduces carbon dioxide in the gas to form an ionic carrier species. An anode chamber with an outlet outputs a gas comprising carbon dioxide. A solid electrolyte membrane spaces the anode chamber from the cathode chamber and transports the ionic carrier species between the cathode chamber and the anode chamber. The membrane includes an ionic liquid. An oxidation catalyst layer in the anode chamber oxidizes the ionic carrier species to form carbon dioxide. A voltage source provides a voltage difference across the membrane.

Abstract: A method of producing functionalized graphene oxide includes mixing graphene oxide with a reactive monomer containing at least one epoxy functional group and a secondary functional group that is selected from vinyl, acrylate, methacrylate, and epoxy to form a mixture, adding an activation agent, heating and stirring the mixture, cooling the mixture, separating the particles from the mixture, and drying the particles to produce functionalized graphene oxide. A method of manufacturing a cured polymer resin using functionalized graphene oxide includes mixing functionalized graphene oxide with a resin precursor to produce a functionalized graphene mixture, wherein the particles contain functional groups nearly identical to, or identical to, a polymer precursor material, adding a curing initiator to the functionalized graphene mixture and mixing to produce a formulation, depositing the formulation into a desired shape, and curing the formulation to form a polymer having functionalized graphene oxide groups in a base polymer material.

Abstract: Additive manufacturing compositions and methods for fabricating a conductive article with the same are provided. The additive manufacturing composition may include a 3D printable material, a plurality of porogens disposed in the 3D printable material, and a metal precursor disposed in the 3D printable material. The metal precursor may include a metal salt, a metal particle, or combinations thereof. The method may include forming a first layer of the article on a substrate, where the first layer includes the additive manufacturing composition, forming a second layer of the article adjacent the first layer, and binding the first layer with the second layer to fabricate the article. The method may also include plating a metal on the article to fabricate the conductive article.
