  • Publication number: 20070112548
    Abstract: The focus of this invention is the combined use of: i) one or more biological agents to promote the precipitation of one or more desired solids onto ii) a biologically-assembled 3-D microscale-to-nanoscale structure. That is, the solid precipitation and the 3-D structural assembly are both conducted with the aid of biology. The biologically-derived 3-D structures may assembled by a biological organism, by a component of a biological organism, by a biological molecule, or by combinations thereof. One or more biological agents is/are used to promote the precipitation of one or more new solids onto the biologically-derived 3-D structure.

  • Patent number: 5681365
    Abstract: A radiation resistant optical waveguide fiber doped with fluorine or drawn with low tension in the fiber. The fluorine doping is substantially constant across the core and a portion of the clad adjacent the core. The concentration of the fluorine is in the range of about 0.3 to 3.0 weight percent. The draw tension is less than or equal to about 5 grams (40 dynes/cm.sup.2) to achieve optimum radiation resistance. A synergy is found when fluorine and low draw tension are applied to a fiber. Improvement in radiation resistance is largely independent of fiber type and geometry. Further improvement in radiation resistance is found when germanium is doped in a portion of the clad adjacent the core.
