Researchers from Zhejiang University report on findings in alloys and compounds

  2008 SEP 15 - (VerticalNews.com) -- "SiC nanowires, SiC/SiO2 core-shell nanocables, and SiC nanotubes have been synthesized simultaneously by direct heating Si powders and multiwall carbon nanotubes (MWCNTs)," scientists in Hangzhou, People's Republic of China report.

  "The as-obtained SiC nanowires are generally 100 nm in diameter and several tens of micrometers in length, the nanocables consist of a 20-30 nm diameters single-crystalline SiC core covered by a uniform layer of about 20 nm thick amorphous SiO2, and the nanotubes with very narrow hollow channel have outer diameters of about 20 nm," wrote B.S. Li and colleagues, Zhejiang University.

  The researchers concluded: "The characteristics of the products are analyzed by various methods, results of which indicating that temperature and ambience are two key factors for the formation of the three different products; their possible growth mechanisms are also discussed."

  Li and colleagues published their study in the Journal of Alloys and Compounds (Simultaneous growth of SiC nanowires, SiC nanotubes, and SiC/SiO2 core-shell nanocables. Journal of Alloys and Compounds, 2008;462(1-2):446-451).
