Tungsten disulphide sheathed carbon nanotubes.

An insulated nanotube wire is formed by the binary phase of layered tungsten disulphide and carbon nanotubes (shown in the HRTEM image) generated by the sulphidization of tungsten oxide coated multiwalled carbon nanotubes at 900 °C. Thermogravimetric analysis shows that the tungsten disulphide coat acts as an antioxidant.

Carbon nanotube template promoted growth of NbS2 nanotubes/nanorods.

NbS2 nanotubes/rods have been generated successfully employing carbon nanotube template promoted growth; high resolution transmission electron microscopy, coupled with EDX analysis, confirm the template effect and existence of NbS2 tube structures.

Novel nanoscale architectures: coated nanotubes and other nanowires.

Research has demonstrated that the structure and properties of a nanoscale system are inextricably linked. The advent of nanoscale research in 1991 relied upon nanoscale material production through random formation techniques, such as arc discharge, and the inherent properties and morphology of the system were therefore difficult to control. This article reviews some of the methods and ideas that have developed since the inception of nanotechnology, leading to fine control over the morphology of nanoscale systems and highlighting some interesting nanoscale architecture.
