Copper@polypyrrole nanocables

Copper@polypyrrole nanocables

A simple hydrothermal redox reaction between microcrystalline CuOHCl and pyrrole leads to the isolation of striking nanostructures formed by polypyrrole-coated copper nanocables. These multicomponent cables that feature single-crystalline face-centered cubic Cu cores (ca. 300 nm wide and up to 200 μm long) are smoothly coated by conducting polypyrrole, which in addition to its functionality, of...

Growth mechanisms of SnO(2)/Sn nanocables.

SnO(2)/Sn nanocables have been grown on single-crystal Si substrates by metal catalyst assisted thermal evaporation of SnO powders. The morphologies and structures of the prepared nanocables were determined on the basis of field emission scanning electron microscopy (FESEM), high-resolution transmission electron microscopy (HRTEM), x-ray diffraction (XRD), Raman and photoluminescence (PL) spect...

Peptide directed synthesis of silica coated gold nanocables.

Here we report a peptide directed synthesis of co-shell nanocables by sequential guide formation of silica insulating shells on metallic gold nanoribbons which is significant since it demonstrated the ability to fabricate a functional nano-electronic component using a biomimetic method.

Synthesis and electrical property of metal/ZnO coaxial nanocables

Ag/ZnO and Cu/ZnO coaxial nanocables were fabricated using AgNO3 or copper foil as source materials by the vapor-liquid-solid process. The coaxial nanocables consist of a crystalline metallic Ag or Cu core and a semiconductor ZnO shell. The evolution of the Ag/ZnO products having different morphologies was investigated by stopping the heating at different temperatures. The diameters of the Ag/Z...
