Ge2Sb2Te5 nanowires (NWs) were synthesized by vaporizing GeTe, Sb, and Te precursors assisted by metal catalysts. Current-voltage measurement of the Ge2Sb2Te5 NW device displays fast and reversible switching between two distinct resistive states, which is due to the crystalline-amorphous phase

A solid-state growth technique is described for the preparation of misfit layered compounds [(Bi2Te3)x{(TiTe2)y}1.36] from preconfigured reactants that provide independent control of both x and y. A procedure for optimizing the structure of the preconfigured amorphous reactants is presented demonstrating

Neurotoxicology, 15(1), 171-180 (1994-01-01)
A compound may be "developmentally neurotoxic" because it interferes with a metabolic step exclusively or preferentially expressed during development in a particular class of neural cells. The initial metabolic specificity is often complicated by: (1) secondary responses in the affected

Tellurium (Te) demonstrates properties similar to those of elements known to be toxic to humans, and has applications in industrial processes, which are rapidly growing in importance and scale. It is relevant, therefore, to consider the tellurium physiology, toxicity, and
