    Abstract: A system and method for removing fouling from a photoelectrocatalytic oxidation assembly is provided. The method includes resetting a first counter, increasing the first counter by a first channel increment value, and determining if the value in the first counter exceeds a value corresponding to the number of channels provided in the assembly. If the first counter does not exceed the number of channels, the polarity in a channel associated with the value in the first counter is reversed, and a first timer is reset. If an amount of time in the first timer does not exceed a first time period, the first timer is increased by a first time increment until the time remaining in the first timer exceeds the first time period and the polarity reversal is terminated, returning to the step of increasing the first counter by a first channel increment value.

The feed can be carbon dioxide, water, methane, or other substances requiring electrolysis. Carbon dioxide and water can be processed into syngas and ozone continuously, enabling carbon and oxygen recycling at power plants. Within the space between the counter-rotating disk electrodes, a shear layer comprising a fractal tree network of radial vortices provides sink flow conduits for light fractions, such as syngas, radially inward while the heavy fractions, such as ozone and elemental carbon flow radially outward in boundary layers against the disks and beyond the disk periphery, where they are recovered as valuable products, such as carbon nanotubes.

  • Patent number: 8419921
    Abstract: It is a task of the present invention to provide an electrolytic apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt, the electrolytic apparatus being advantageous in that the electrolysis can be performed without the occurrence of the anode effect even at a high current density and without the occurrence of an anodic dissolution. In the present invention, this task has been accomplished by an electrolytic apparatus for producing fluorine or nitrogen trifluoride by electrolyzing a hydrogen fluoride-containing molten salt at an applied current density of from 1 to 1,000 A/dm2, the electrolytic apparatus using a conductive diamond-coated electrode as an anode.

  • Patent number: 8409422
    Abstract: This invention relates to a process and an apparatus for generating hydrogen and oxygen gas by electrolysis of water. The process involves forming an electrolyte including alkaline ions and the water and generating plasma between electrodes immersed in the electrolyte by applying an electrical potential between the electrodes. The plasma ionizes the electrolyte, thereby generating hydrogen and oxygen gas. The process further involves controlling the process by relocating the generated plasma between two or more further electrodes.

  • Publication number: 20130068629
    Abstract: Improvements in an ocean wave energy conversion unit that converts kinetic energy from oceanic waves into useable form of energy that will benefit society called and Aqua-tamer. The unit is designed to be modular in nature where the units can be deployed to function individually or assembled into groups where units will rely on each other and function together as a whole. Each individual unit has an electrical output. As a group (Colony) during deep sea surface applications, the electrical output of each Aqua-Tamer unit will be consolidated and used to operate a water-electrolysis operation that produces Oxygen Gas (O2) and Hydrogen Gas (H2). This production of O2 and H2, instead of electrical output, is designed to eliminate the requirements of an Ocean-wide electrical grid system and still facilitate an economic logistically efficient) method of energy transportation (energy in a gas state.

  • Patent number: 8361337
    Abstract: Nanopatterned substrates can be prepared by a method that includes forming a block copolymer film on a substrate, annealing the block copolymer film, surface reconstructing the annealed block copolymer film, coating an etch-resistant layer on the surface reconstructed block copolymer film, etching the resist-coated block copolymer film to create an etched article comprising a nanopatterned substrate, and separating the etch-resistant layer and the block copolymer film from the nanopatterned substrate. The method is applicable to a wide variety of substrate materials, avoids any requirement for complicated procedures to produce long-range order in the block copolymer film, and avoids any requirement for metal functionalization of the block copolymer.

  • Patent number: 8342207
    Abstract: The invention relates to a microfluidic device for making a liquid/liquid or gas biphasic system using a first liquid or a gas and a second liquid, non-miscible with each other, the device having a first hydrophobic surface for the second liquid, the first liquid forming a layer (6) on said first hydrophobic surface. The device comprises means for introducing a drop (7) of the second liquid into the layer of first liquid or gas and in contact with said first hydrophobic surface, and means for displacing the drop on said first hydrophobic surface along a determined path, the device having on the path of the drop, at least one wetting defect causing, upon passing of the drop over this defect, failure of the triple line of contact of the drop on the first hydrophobic surface and inclusion of first liquid (8) or gas into the drop. The invention also relates to the associated method.
