“…It has been shown by theoretical analysis that sp 3 diamond nucleation from sp 2 carbon is possible inside carbon nanotubes or nanoparticles due to surface tension effects [39] and there have been many attempts to convert carbon nanotubes to diamonds using plasma techniques, laser irradiation, shock waves and plasma sintering [40][41][42] but all these techniques require very high pressures and temperatures as well as metallic catalysts. Non-metallic catalysts, such as alkali carbonates, have also been used although even higher temperatures and pressures are required as well as longer reaction times [43].…”

The electrochemical interaction between graphite and molten salts to produce carbon nanostructures is reviewed. It is demonstrated that, depending on the conditions, it is possible to electrochemically convert graphite in molten salts to either carbon nanoparticles and nanotubes, metal filled carbon nanoparticles and nanotubes, graphene or nanodiamonds. The application of metal filled carbon nanotubes as anodes in lithium ion batteries is reviewed. Surprisingly, this method of preparation is relatively simple and very similar to the mass production of aluminium in molten sodium aluminium fluoride-alumina mixtures, which is performed economically on a tonnage scale, indicating that it may be possible to apply it for the production of novel carbon nanostructures.

Diamond is a wide band gap semiconductor exhibiting a combination of superior properties, such as negative electron affinity, chemical inertness, high Young's modulus, the highest hardness and room-temperature thermal conductivity, etc. It is possible to control and enhance the fundamental properties of diamond by fabricating 1D diamond nanowires, due to the giant surface-to-volume ratio enhancements of 1D nanowires. Although theoretical comparisons with carbon nanotubes have shown that diamond nanowires are energetically and mechanically viable structures, reproducibly synthesizing the crystalline diamond nanowires has remained challenging. In this chapter, we present a comprehensive, up-to-date review for the diamond nanowires, wherein we will give a discussing for their synthesis along with their structures, properties and applications.

“…Furthermore, nanowires may act as functional part in a quantum computer [20]. Diamond nanorods are an increasingly popular example [21][22][23]. Molecular wires involving benzene are often modelled in a planar geometry such as polyacene and polyphenanthrene [24,25].…”
