ZnO nanowires with diameters of 40–200 nm were grown with a gold catalyst in bulk quantities on alumina substrates and sapphire substrates. This synthesis procedure was achieved by heating a 1:1 mixture of ZnO and Zn powder to 500 °C with trace water vapor as an oxidizer. X-ray diffraction and transmission electron microscopy revealed that the nanowires were in the pure wurtzite phase. Photoluminescence spectroscopy showed two peaks: one was a strong ultraviolet emission at around 380 nm, which corresponds to the near-band-edge emission; the other was a weak near-infrared emission around 750 nm, which indicates a low concentration of oxygen vacancy. Moreover, we observed that the Zn/Au alloy droplets appeared on the tips of ZnO nanowires. As a consequence, we can select areas to grow ZnO nanowires by patterning the thin metal film on the substrates. These findings prove that the low-temperature growth mechanism is via vapor–liquid–solid rather than vapor transport deposition or vapor supersaturation (vapor–solid) mechanism. On the basis of the site-specific growth and the low-temperature requirement developed from this work, the synthesis of ZnO is compatible to microelectric machining system processing.

Cold hardness and ice encasement tolerance of 'Fredrick' and 'Norstar' winter wheats as affected by infection with barley yellow dwarf virus (BYDV) were determined during inoculation, disease development periods, and low-temperature growth. Plants were either prehardened to cold, or warm grown before infection; two disease development periods (DDP) were utilized. A long DDP induced greater pathogenesis and greater hardiness reduction than a short DDP. The effect of virus infection on the final level of hardiness of prehardened plants was generally greater than on that of nonprehardened plants. Viral infection reduced hardiness up to 3.5 °C in 'Fredrick' wheat, but reductions of 6–10 °C below hardiness potential were recorded after certain environmental regimes allowing disease development. Ice tolerance was reduced by BYDV infection in early low-temperature growth but was increased by infection after 4 months at low temperature. This increase in survival was associated with higher dry matter content in infected than in noninfected plants.
