Nanowires, anisotropic synthesis

A novel route for the synthesis of Si02 and Ti02 nanotubes with rectangular cross-section is developed. The high metal content and their anisotropic morphology render these tubelike nanocomposites attractive materials for nanoelectronics. In order to realize probable applications as nanowires, the synthesis route must be further optimized to obtain tubes, which are uniform in length and width. 

Dozens of methods to synthesize nanotubes, nanowires, and nanorods have been reported that can be found in the references included in Table 1. In addition to the most well known ones, such as hot plasmas, laser ablation, chemical vapor deposition, high temperature solid state and hydrothermal synthesis, fill-ing/coating of carbon nanotubes and similar types of materials, three methods have been developed that enable the synthesis of a wealth of new anisotropic nanoparticles.
