14997 – An energy efficient process for the separation of gases by selectively permeable membranes To counteract economic and environmental problems due to the burning of fossil fuels, society has placed an emphasis on development of renewable energy sources. Some of these renewable energy sources rely on the separation or removal of acid gases, such as carbon dioxide, hydrochloric acid,... Read More
14923 – An improved thin-film composite membrane which will efficiently purify greater amounts of water for reverse osmosis applications Access to potable, contaminant-free water is increasingly difficult in developing countries. Water purification by reverse osmosis is a potential solution, but only 12,500 desalination plants exist and less than 1% of the world’s total water consumption is... Read More
15002 – A technology capable of reducing concentration polarization and therefore minimize membrane fouling that arises during membrane-based separation, filtration, or concentration processes. Desalination produces potable water in areas of the world that have unreliable access to fresh water. The most common method of desalination requires a membrane-based filtration system to filter salt... Read More
37385 – A process for photoelectrochemical reduction of carbon dioxide to acetate using mixed metal oxide as catalysts The combustion of fossil fuels produces billions of tons of carbon dioxide annually. Research indicates that greater concentrations of carbon dioxide in the atmosphere has altered Earth’s climate, changed the pH of the ocean, and causing other potentially damaging evironmental...
