Abstract: An electrochemical device comprises a first type of membrane disposed between first and second reservoirs containing an input solution, and a second type of membrane, different from the first type, is disposed between a first redox-active electrolyte chamber and the first reservoir and disposed between a second redox-active electrolyte chamber and the second reservoir. The first type of membrane and one of the second type of membranes form a membrane pair and the pair has an area specific resistance below y=5065.3x3−1331.1x2+90.035x+39 Ohm cm2 when the pair is equilibrated in an electrolyte and for at least part of a range where 0

Abstract: A porous polymer aerogel, wherein the aerogel has greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone. A method of fabrication of a porous polymer aerogel amine material, includes preparing a solution comprising at least a solvent, amine monomers having protected amino groups, one or more crosslinkers, one or more radical initiators, and a nitroxide mediator, removing oxygen from the solution, 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 groups protecting the amino groups, soaking and rinsing the material to remove excess reagents and any byproducts of the deprotection reaction, and drying the material to produce the amine sorbent. A system to separate CO2 from other gases, comprising a polymer porous aerogel sorbent having greater than 5 wt % of amine containing vinyl monomers integrated into a polymer backbone.

Abstract: A device controls levels of carbon dioxide and water in a controlled environment. The device comprises a first electrode chamber, which receives an input fluid comprising first concentrations of carbon dioxide and water and is configured to deliver a first output fluid having concentrations of carbon dioxide and water lower than the first concentrations to a first environment, and a second electrode chamber having an outlet configured to deliver a second output fluid having third concentrations of carbon dioxide and water to a second environment. A reduction catalyst layer in the first electrode chamber reduces carbon dioxide and water in the input fluid to form ionic carrier species, an ion-transporting membrane is positioned between the first and second electrode chambers and comprises carrier species, and an oxidation catalyst layer in the second electrode chamber oxidizes the ionic carrier species to form carbon dioxide and water.

Abstract: A polymer electrolyte membrane includes an ion-conducting polymeric electrolyte material and platelets, distributed through the polymeric electrolyte material. The platelets have an aspect ratio of length to thickness of at least 2:1. The platelets are aligned generally parallel to a length of the membrane. The platelets can be functionalized with free radical scavengers, or other moieties, to extend the lifetime of the membrane or of a membrane electrode assembly incorporating the membrane.
