Formation, structure, and stability of titanate nanotubes and their proton conductivity

Article Abstract:

High yield H-form trititanate nanotubes are synthesized, and their structures are characterized by using X-ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM). Structural characterizations by XRD and HRTEM further give indications that the structure of the nanotubes can be regarded as a result from rolling up individual sheets of H(sub 2)Ti(sub 3)O(sub 7).

High-yield synthesis of single-wall carbon nanotubes on MCM41 using catalytic chemical vapor deposition of acetylene

Article Abstract:

High-quality single-wall carbon nanotubes (SWNTs) with narrow diameter distribution are grown on Fe/Co-loaded MCM41 by using acetylene as the carbon source within a short reaction period. The method is found to be appropriate for the preparation of a bimetal catalyst leading to a high-yield synthesis of SWNTs in a short time scale.

First-principles studies of SnS2 nanotubes: A potential semiconductor nonowire

Article Abstract:

The study used first principles calculations to predict the stability and electronic structures of SnS2 nanotubes. Ban structure calculations concluded that SnS2 nanotubes could have moderate band gaps regardless of their chirality.
