  • Syntheses and structures of new inorganic borates

    Creator:
    Sun, Hongxing
    Abstract:
    Several new solid-state inorganic borates have been prepared and characterized. Single crystals of the simple orthoborate ScB0₃ were grown and its structure was determined by single-crystal X-ray methods. The new borates Li₃Sc(B0₃)₂, LaSc₃(B0₃)₄, NdSc₃(B0₃)₄, SrNaB0₃, and Li4Ln4MB90₂₃ (Ln = Y, Er, and Gd; M = Al and Ga) were identified...

  • The biology and seasonality of the parasitiod Trioxys pallidus Haliday in western Oregon

    Creator:
    Cohn, Judy L.
    Abstract:
    Seasonal synchrony between the filbert aphid, Myzocallis coryli (Goetze) and its newly introduced parasitoid Trioxys pallidus Haliday was examined in the field to evaluate the effectiveness of parasitoid based biological control in filbert orchards of Oregon. Fieldemergence observations showed that 50% eclosion of the aphid occurred 14 days before that...
