Abstract: Apparatuses and methods for removing carbon dioxide and other pollutants including heavy metals from a gas stream are provided. The methods include obtaining a water-condensate from the flue-gas stream; obtaining a chloride salt; admixing the salt with water, steam, or both to produce a solution; electrolyzing the solution to produce a hydroxide and chlorine gas; admixing a portion of the hydroxide with the flue-gas stream to produce carbonate products, bicarbonate products, or a mixture of carbonate and bicarbonate products in an admixture; separating said carbonate and/or bicarbonate products from the admixture, thereby removing carbon dioxide from the flue-gas stream; adding a portion of the hydroxide to the water-condensate to change the pH of the water-condensate from acidic to basic, resulting in precipitation of the heavy metals; and passing the water-condensate through a filtering medium.

Abstract: The present invention relates to carbon dioxide sequestration, including processes in which group-2 silicates are used to remove carbon dioxide from waste streams to form corresponding group-2 carbonates and silica.

Abstract: Methods for removing carbon dioxide and other pollutants from a gas stream are provided. The methods include obtaining hydroxide in an aqueous mixture, mixing the hydroxide with the gas stream to produce bicarbonate products or a combination of carbonate and bicarbonate products in an admixture, separating the products from the admixture, and using the products to perform ion-exchanges with one or more group-1 or group-2 salts to precipitate carbonates, wherein obtaining the hydroxide comprises obtaining a group-1 or group-2 salt; mixing the salt with acid and water, acid and steam, or acid, water, and steam to produce a protonated brine solution; and electrolyzing the protonated brine solution to produce a hydroxide; and wherein mixing the hydroxide with the gas stream comprises altering the product equilibrium to favor the production of bicarbonate products.

Abstract: A new system and method for high-speed testing of semiconductor devices is disclosed. The system utilizes bi-directional FET switches to hide the delay related to the distance signals have to travel between the test head electronics and the device under test. The effect is to increase the frequency with which a prior art tester can test a device. By placing the FET switches closer to the device under test, the device operates on the tester in the same electrical environment as it would in actual use. The device under test can be switched from receiving an input signal to driving an output signal in less time than the TL delay between the test head electronics and the device under test.
