Abstract: The present disclosure is related to porous media with adjustable fluid permeabilities and related systems and methods. In certain cases, the fluid permeability of a porous medium can be adjusted by applying an electrical potential to the porous medium. In some such cases, the application of the electrical potential to the porous medium results in the deposition of material over or the removal of material from the porous medium. Also disclosed herein are systems and methods for capturing species (e.g., acid gases) in which porous media with adjustable fluid permeabilities are used, for example, to control the flow of fluid into and out of a medium used to capture the species.

Abstract: Methods, apparatuses, and systems related to electrochemical capture of Lewis acid gases from fluid mixtures are generally described. Certain embodiments are related to electrochemical methods involving selectively removing a first Lewis acid gas from a fluid mixture containing multiple types of Lewis acid gases (e.g., a first Lewis acid gas and a second Lewis acid gas). Certain embodiments are related to electrochemical systems comprising certain types of electroactive species having certain redox states in which the species is capable of binding a first Lewis acid gas but for which binding with a second Lewis acid gas is thermodynamically and/or kinetically unfavorable. The methods, apparatuses, and systems described herein may be useful in carbon capture and pollution mitigation applications.

Abstract: An asymmetric system containing a first conductive polymer modified with a redox active moiety and a second conductive polymer modified with a surfactant is used for the separation of organic compounds from aqueous solutions. The asymmetric system has complementary hydrophobicity tunability in response to electrochemical modulations. For example, both materials are hydrophobic in their respective neutral states, therefore exhibiting affinity toward organic compounds. Application of a mild potential drives the desorption of the organic compounds and regeneration of the materials. The asymmetric system can be used in a cyclic fashion, through repeated electrical discharge or shorting of the two electrodes to program the capture of organics from a feed solution, and application of a potential to stimulate the release of the adsorbed organics.

Abstract: Methods, apparatuses, and systems related to the electrochemical separation of target gases from gas mixtures are provided. In some cases, a target gas such as carbon dioxide is captured and optionally released using an electrochemical cell (e.g., by bonding to an electroactive species in a reduced state). Some embodiments are particularly useful for selectively capturing the target gas while reacting with little to no oxygen gas that may be present in the gas mixture. Some such embodiments may be useful in applications involving separations from gas mixtures having relatively low concentrations of the target gas, such as direct air capture and ventilated air treatment.

Abstract: A carbon-capture device and related processes are disclosed. The devices include substrate surfaces having a textured surfaces and a liquid sorbent contacting the texture surface in either a Cassie-Baxter state, in the case of a texture omniphobic surface or a plurality of re-entrant features or a Wenzel state, in the case of a textured omniphilic surface. The liquid sorbent reversibly captures a chemical species, which can usefully be carbon dioxide. This reversible capture can be exploited to capture and sequester carbon or other chemical species of interest.
