  • Publication number: 20130137171
    Abstract: The present method transfers carbon dioxide in increased concentrations using perfluorodecalin for growth of algae in a photobioreactor. First, a perfluorodecalin solution is provided and mixed with a biological growth medium and a surfactant. The biological growth medium, perfluorodecalin solution, and surfactant mixture are then emulsified by circulation in a high-pressure emulsifier. The emulsified biological growth medium, perfluorodecalin solution, and surfactant mixture are then added to a photobioreactor containing algae capable of photosynthetically utilizing carbon dioxide. After adding carbon dioxide to the photobioreactor, the carbon dioxide dissolves in the perfluorodecalin solution at a higher concentration than in the growth medium.

  • Patent number: 8197857
    Abstract: A method for the elimination of carbon dioxide from waste gases includes the following steps. First, waste gases, which include carbon dioxide, are provided from a source for waste gases. Next, the waste gases are contacted with an absorbent composition that includes perfluorodecalin solution. The waste gases, especially the carbon dioxide, are then absorbed by the absorbent composition. The absorbent composition thereby absorbs the waste gases to eliminate the carbon dioxide.

  • Patent number: 5968854
    Abstract: An electromagnetic shielding fabric is formed entirely from a plurality of synthetic fiber yarns which have been previously coated with silver. The preferred yarn structure comprises silver-coated nylon yarns, although other synthetic yarns can also be used as a base for the silver-coated yarns. The silver content of the silver-coated synthetic yarn is preferably not less than 20% by weight, and the conductivity of the silver-coated yarn is preferably not less than 1.2 ohms/cm. The silver-coated synthetic yarns are preferably formed into a planar textile material by means of a warp-knitting method which interlocks all of the yarns in a continuous chain stitch. The resulting fabric is thus formed entirely of the conductive silver-coated yarns thereby providing superior conductivity and electromagnetic shielding capability.
