Study on Au nanoparticles TiO"2 nanoclusters and SiO"2 nanoshells coat

Multi-wall carbon nanotubes (MWCNTs) coated with crystalline Au nanoparticles, TiO2 nanoclusters, andamorphous SiO2 nanoshells, to represent conductors, semiconductors, and insulators, respectively, wereembedded in transparent silica gel-glass. The coated MWCNT/silica gel-glasses were prepar
