摘要： Systems and methods for fixing carbon using bacteria are described. In one embodiment, a system includes a reactor chamber with a solution contained therein. The solution may include hydrogen (H2), carbon dioxide (C02), bioavailable nitrogen, and a chemolithoautotrophic bacteria. The system may also include a pair of electrodes that split water contained within the solution to form the hydrogen. Additionally, the system may be operated so that a concentration of the bioavailable nitrogen in the solution is below a threshold nitrogen concentration to cause the chemolithoautotrophic bacteria to produce a product.

摘要： Provided are a macroporous titanium compound monolith and a production method thereof, the macroporous titanium compound monolith having a framework that is composed of a titanium compound other than titanium dioxide, having controlled macropores, and having electron conductivity, the titanium compound being oxygen-deficient titanium oxide, titanium oxynitride, or titanium nitride. Provided is a method including: placing a macroporous titanium dioxide monolith and a metal having titanium-reducing ability in a container, the macroporous titanium dioxide monolith having a co-continuous structure of a macropore and a framework that is composed of titanium dioxide; creating a vacuum atmosphere or an inert gas atmosphere within the container; and heating the monolith and the metal to cause gas-phase reduction that removes oxygen atom from the titanium dioxide composing the monolith by the metal acting as an oxygen getter, thereby obtaining a macroporous oxygen-deficient titanium oxide monolith having a co-continuous structure of the macropore and a framework that is composed of oxygen-deficient titanium oxide, the macroporous oxygen-deficient titanium oxide monolith having electron conductivity derived from the oxygen-deficient titanium oxide.

摘要： In a submerged discharge device, a pair of electrodes is arranged in a liquid in a reservoir to receive an alternating voltage from an alternating power source, thereby generating a submerged discharge using a discharger arranged in the liquid between the pair of electrodes. A surface of this pair of electrodes has a coating that ensures the submerged discharge generated by the discharger. This may reduce the area of contact between the surface of the pair of electrodes and the liquid in the treatment vessel to reduce the consumption of the pair of electrodes.
