Abstract: A method of producing a polymer aerogel includes dissolving precursors into a solvent, wherein the precursors include monomers, crosslinkers, a controlling agent and an initiator to form a precursor solution, wherein at least one of the monomers or at least one of the crosslinkers has a refractive index of 1.5 or lower, polymerizing the precursor solution to form a gel polymer, and removing the solvent from the gel polymer to produce the polymer aerogel. A method of producing a polymer aerogel include dissolving precursors into a solvent, wherein the precursors include monomers, crosslinkers, a controlling agent and an initiator to form a precursor solution, polymerizing the precursor solution to form a gel polymer, removing the solvent from the gel polymer to produce the polymer aerogel, and reducing a refractive index of one of either the gel polymer or the polymer aerogel.

Abstract: A deposition system has a multi-material print head, a first reservoir of a first compatible material having particles containing chemical elements similar to a first substrate, a second reservoir of a second compatible material having particles containing chemical elements similar to a second substrate, a third reservoir of an polymer precursor material, and at least one mixer. A method of bonding a joint between dissimilar substrate materials includes functionalizing a first compatible material having chemical elements similar to a first substrate, mixing the first compatible material with a polymer precursor material, functionalizing a second compatible material having chemical elements similar to a second substrate, mixing the second compatible material with a polymer precursor material, and using the deposition system to deposit the first and second compatible materials and a polymer precursor material on the joint between the first and second substrate materials.

Abstract: A method of fabrication of a porous polymer aerogel amine material includes preparing a solution comprising at least a solvent, amine monomers having protecting groups, one or more crosslinkers, and one or more radical initiators, heating the solution to promote polymerization and to produce a polymerized material, performing solvent exchange with the polymerized material, causing a deprotection reaction in the polymerized material to remove the protecting groups to produce a deprotected material, soaking and rinsing the deprotected material to remove excess reagents and any byproducts of the deprotection reaction, and drying the deprotecting material to produce the amine sorbent. A system to separate CO2 from other gases has a polymer porous aerogel sorbent having greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone, and the amine containing vinyl monomers may have a molecular weight of less than 100 g/mol.

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: A test strip includes a substantially transparent substrate and one or more colorimetric test spots on the transparent substrate. Each colorimetric test spot has one or more sensing chemicals chemically attached onto a porous support material. The porous support material has at least one exposed surface configured to absorb a body fluid. The one or more sensing chemicals are configured to change a color in response to a presence of a target drug in the body fluid.

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.
