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

Despite being disparaged for their malodorous and toxic demeanour, compounds of selenium, a bio-essential element, and tellurium, offer possibilities as therapeutic agents. Herein, their potential use as drugs, for example, as anti-viral, anti-microbial, anti-inflammatory agents, etc., will be surveyed along
