Abstract: Provided herein is a stand-alone self-powered portable direct-air-capture (DAC) carbon dioxide removal system. In some embodiments the DAC compromises 1) a wind turbine; 2) at least one solar panel; 3) an energy storage device; 4) a liquid-air contactor; 5) an electrodialysis bipolar membrane (EDBM) device; 6) an acid tank; 7) a base tank; 8) a mixing tank, and 9) at least one CO2 sequestration pump. In some embodiments, the liquid-air contactor overcomes the need to pass large amounts of air over the contactor device using wind. In some embodiments, the EDBM lowers energy requirements to less than 1.2 MJ/Kg CO2 compared to thermal regeneration systems (3.5-4 MJ/Kg/CO2).

Abstract: Quantum dots that are cadmium-free and/or stoichiometrically tuned are disclosed, as are methods of making them. Inclusion of the quantum dots and others in a stabilizing polymer matrix is also disclosed. The polymers are chosen for their strong binding affinity to the outer layers of the quantum dots such that the bond dissociation energy between the polymer material and the quantum dot is greater than the energy required to reach the melt temperature of the cross-linked polymer.

Abstract: Exemplary embodiments relate to methods for removal of CO2 and other acid gases from gaseous fuels prior to combustion. Exemplary methods may be used for CO2 capture, H2 purification and natural gas sweetening. Exemplary methods use at least one ionic liquid that has excellent CO2 solubility, selectivity over hydrogen, low viscosity, and resistance to H2S.

Abstract: Herein, we describe polymerized ionic liquids, demonstrate the synthesis of polymerized ionic liquids, and demonstrate the polymerization of triazolium monomers. One embodiment shows the polymeriazation of the triazolium monomers with bis(trifluoromethanesulfonyl)imide anions. In another embodiment we show the feasibility of copolymerizing with commodity monomers such as styrene using free radical polymerization techniques.

Abstract: Methods and compositions useful, for example, for physical solvent carbon capture. A method comprising: contacting at least one first composition comprising carbon dioxide with at least one second composition to at least partially dissolve the carbon dioxide of the first composition in the second composition, wherein the second composition comprises at least one siloxane compound which is covalently modified with at least one non-siloxane group comprising at least one heteroatom. Polydimethylsiloxane (PDMS) materials and ethylene-glycol based materials have high carbon dioxide solubility but suffer from various problems. PDMS is hydrophobic but suffers from low selectivity. Ethylene-glycol based systems have good solubility and selectivity, but suffer from high affinity to water. Solvents were developed which keep the desired combinations of properties, and result in a simplified, overall process for carbon dioxide removal from a mixed gas stream.

Abstract: Methods and compositions relating to poly(hydroxyl urethane) compounds are described herein that are useful as, among other things, binders and adhesives. The cross-linked composition is achieved through the reaction of a cyclic carbonate, a compound having two or more thiol groups, and a compound having two or more amine functional groups. In addition, a method of adhesively binding two or more substrates using the cross-linked composition is provided.
