Abstract: A sensor has a transparent polymer aerogel, and sensing materials dispersed into the transparent, polymer aerogel, where the sensing materials change color in response to environmental conditions. A method of forming a sensor includes providing a substrate, forming a polymer aerogel layer on the substrate, and infusing the polymer aerogel layer with sensing molecules.

Abstract: Methods comprising: evaporating a catalyst source to produce a catalyst gas; condensing the catalyst gas to produce a catalyst vapor comprising catalyst droplets suspended in a gas phase; and contacting the catalyst vapor with a hydrocarbon gas to catalyze a decomposition reaction of the hydrocarbon gas into hydrogen gas and carbon. And, systems comprising: a catalyst source evaporator that provides a first stream to a reactor; a hydrocarbon source that provides a second stream to the reactor; a cooling column coupled to the reactor via a third stream comprising hydrogen, catalyst liquid, solid carbon, optionally catalyst gas, and optionally unreacted hydrocarbon gas such that the cooling column receives the third stream from the reactor; and wherein the cooling column has effluent streams that include (a) a fourth stream that comprises hydrogen and optionally catalyst gas and (b) a fifth stream that comprises catalyst liquid.

Abstract: A solution flows through a salinate chamber and a desalinate chamber of an electrochemical cell. Solutes are moved from the desalinate chamber to the salinate chamber to create respective solvent and concentrate streams from the desalinate and salinate chambers. The concentrate stream flows to a recombination cell where it is combined with a solvent. The combination causes at least one of an absorption of heat within the recombination cell and emission of heat from the recombination cell.

Abstract: A system has an alkaline capture stream as an input, an alkaline depleted stream as an output, a carbon dioxide removal unit operation having a return stream as an output, and a series of electrolyzers, each electrolyzer to receive a CO2-rich input stream and produce an acidified output stream that is more acidic than the CO2-rich input stream, and to receive a return stream and produce a basified output stream that is more alkaline than the input return stream. A method of removing carbon dioxide from an atmosphere and generating hydrogen includes capturing carbon dioxide from an atmosphere in an alkaline capture solution, sending the alkaline solution as a CO2-rich input solution to a series of electrolyzers in a CO2-rich path, removing carbon dioxide from the acidified CO2-rich solution at a removal unit to produce a CO2-poor solution, sending the CO2-poor solution to the series of electrolyzers in a return path, and returning the return solution to the alkaline capture stream. An electrolyzer is also discussed.

Abstract: A method for producing a homogenous molten composition and a fluid product is disclosed. For example, the method includes producing a first molten metal composition in an enclosed volume, contacting a hydrocarbon reactant with the first molten metal composition, decomposing the hydrocarbon reactant into at least one fluid product and carbon, forming a metal alloy from a mixture of the carbon and the first molten metal composition, and separating a homogenous second molten composition from the metal alloy.

Abstract: A system comprises an electrodialysis apparatus, which includes first and second reservoirs, wherein a salt concentration in the first reservoir reduces below a threshold concentration, and salt concentration in the second reservoir increases during an operation mode. A first electrode comprises a first solution of a first redox-active electrolyte material, and a second electrode comprises a second solution of a second redox-active electrolyte material. In a first reversible redox reaction between the first electrode and first electrolyte material at least one ion is accepted from the first reservoir, and in a second reversible redox reaction between the second electrode and second electrolyte material at least one ion is driven into the second reservoir. A first type of ion exchange membrane is disposed between the first and second reservoirs, and a second type of ion exchange membrane, different from the first type, is disposed between the respective electrodes and reservoirs.
