  • Publication number: 20100009267
    Abstract: The present invention generally relates to metal oxide fibers and nanofibers, the processes for making same, and uses thereof. Such metal oxide nanofibers possess the ability to absorb and decompose chemical warfare agents and other toxic chemicals. These nanofibers can be incorporated into protective clothing and devices for breathing or in another example may be used in lithium-ion batteries. In one embodiment, the present invention relates to titania, alumina, and/or magnesia fibers and nanofibers, and to processes for making same. In another instance, alpha-phase aluminum oxide is utilized as one material in nanofibers.

  • Patent number: 5174873
    Abstract: A method of isotope enrichment including providing a reactant. The reactant is a mixture of at least two isotopic compounds. One of the isotopic compounds has a greater percentage of a selected isotope than the other. An electron transfer agent is introduced into the reactant isotopic mixture to form a reaction mixture. The electron transfer agent facilitates transfer of electrons interactive with one or more selected nuclei of the reactant. The electron transfer agent is in an amount sufficient upon reaction of the reaction mixture to establish an equilibrium between an electron rich reaction product and an electron poor reaction product. The reaction mixture is reacted until the equilibrium is established. The electron poor reaction product is then separated from the electron rich reaction product.

  • Patent number: 4849075
    Abstract: A method of isotope enrichment comprises providing a mixture of at least two isotopic compounds of a reactant. One of the components having a greater percentage of a selected isotope than the other. An electron transfer agent is introduced into the mixture to form a reaction mixture. The electron transfer agent facilitates the transfer of electrons interactive with nuclei of the selected element in the reactant. The transfer agent is in an amount sufficient upon reaction of the reaction mixture to establish an equilibrium between an electron rich reaction product and an electron poor reaction product. The reaction mixture is reacted until the equilibrium is established. Molecules of the electron poor reaction product are then separated from molecules of the electron rich reaction product.
