Abstract: A method of making a material for capturing carbon dioxide from the earth's atmosphere, comprises producing an acid and a base with an electrochemical acid-base generator; dissolving a mineral in the acid to produce a mineral rich solution, separating silica from the mineral rich solution to form a silica depleted solution; adding a first portion of the base to the silica depleted solution to remove impurities by precipitation, adding a second portion of the base until ferrous hydroxide (Fe(OH)2) precipitates, then pausing base addition and removing the ferrous hydroxide precipitate from the solution. Then adding a third portion of the base to the iron-depleted solution to precipitate magnesium hydroxide (Mg(OH)2) and/or calcium hydroxide (Ca(OH)2). Then recovering a salt solution and directing the recovered salt solution to the electrochemical acid-base generator to

Abstract: Modified chemical structures of cardanol extracted from cashew nut shell oil, and the use of the same to prepare imidazolium ionic liquids (IILs). The IILs can be used to prepare different types of silica, magnetite and calcium carbonate nanoparticles (NPs) as multifunctional oilfield chemicals for use in various oil spill collection, de-emulsification, viscosity improvement, asphaltene dispersant, and enhanced oil recovery applications.

Abstract: Methods and systems for enhancing water treatment and desalination are provided. An example method includes generating structurally altered gas molecules from water, where the structurally altered gas molecules have a higher probability of attraction of electrons into areas adjunct to the structurally altered gas molecules than molecules of the water. The method further includes mixing the structurally altered gas molecules with raw water to modify properties of the raw water, thereby increasing raw water filtering efficiency of a water filtering system.

Abstract: Methods and systems integrate direct carbon capture and desalination processes to various degrees, benefiting from synergies in the combined processes. A method includes receiving an input liquid comprising a brine reject stream from a water treatment facility and pre-treating the input liquid. The pre-treatment includes one or more of filtration, a reverse osmosis, and ion exchange. The method also includes performing an electrochemical process on the input liquid to produce at least one hydroxide-rich stream and capturing CO2 from air using the hydroxide-rich stream and a passive air capture system, thereby producing a liquid carbonate solution containing air-captured CO2. In some cases byproducts and recovered water can be used by the water treatment facility and/or the carbon capture process.
