  • Patent number: 6207073
    Abstract: A method and composition for the remediation of environmental contaminants in soil, sediment, aquifer material, water, or containers in which contaminants were contained, wherein contaminants are reacted with a remediating composition comprising a metal and a sulfur-containing compound to produce environmentally-acceptable, chemically reduced products. The method is useful for treating contaminants such as halogenated hydrocarbons, pesticides, chemical warfare agents and dyes. The remediating composition preferably contains comminuted, commercial grade iron and iron sulfide. The addition of an alcohol to the reactants enhances the rate of the remediation reaction, particularly for contaminants of soils and sediments.

  • Patent number: 6100382
    Abstract: A method and composition for the remediation of environmental contaminants in soil, sediment, aquifer material or water wherein contaminants are first reduced with a reducing agent found in sediment and are then oxidized to environmentally safe products. The composition includes a reducing agent, solubilized from sediment by a solvent, for reduction of environmental contaminants such as nitroorganics, halogenated hydrocarbons, cyano compounds, anisoles and metals.

  • Patent number: 5190879
    Abstract: Containers utilizing economical gas-permeable, ultra-thin dense skin polydimethylsiloxane membranes incorporating porous substrates as passive contaminant barriers in containment systems for research, breeding, housing, and shipping of animals, including fish, birds, and mammals, and plants, or animal, plant or microbial cells. These membranes protect the animals from airborne pathogens while permitting exchange of respiratory gases and metabolic heat, as well as protect laboratory personnel, mail handlers, and others who come in contact with or transport the animals from animal borne allergens and infectious agents.

    Assignee: Bowolfe, Inc.
    Inventors: N. Lee Wolfe, Franklin W. Range
  • Patent number: 5173225
    Abstract: A ultra-thin dense skin gas-controlling membrane that is impermeable to liquids, bacteria, and viruses, yet is permeable to small molecular weight gases, such as O.sub.2, CO.sub.2, NH.sub.3, N.sub.2, and water vapor, and a method for making the membrane. The membrane possesses specific gas transfer characteristic making it suitable for use in the culturing of biological materials. The membrane is incorporated into cell culture apparatus, such as roller bottle caps, for the benefit of optimally maintaining O.sub.2 and CO.sub.2 levels in the tissue culture container during all phases of cell growth. The membrane also acts as an absolute barrier to microbial contamination of the culture media within the culture container.
