  • Biological insertion of nanostructured germanium and titanium oxides into diatom biosilica

    Creator:
    Jeffryes, Clayton S.
    Abstract:
    There is significant interest in titanium oxide and germanium-silicon oxide nanocomposites for optoelectronic, photocatalytic, and solar cell applications. The ability of the marine diatom Pinnularia sp. to uptake soluble metal oxides from cell culture medium, and incorporate them into the micro- and nano-structure of their amorphous silica cell walls, called...

  • Phylogeny of the "Chaoboriform" genera

    Creator:
    Ogawa, Joshua R.
    Abstract:
    The phantom midges (Diptera: Chaoboridae) are a relatively small fly family composed of 50 extant species in six genera. Larvae are of interest to limnologists and ecologists because of their tolerance to toxicants, predatory avoidance strategies, and the role chaoborids play in zooplankton community dynamics. Relative to mosquitoes, systematists have...
