ABSTRACT:
A method and apparatus for production of nanoscale materials is disclosed. In the preferred embodiments, the invention is scalable and tunable to reliably produce nanoscale materials of specifically desired qualities and at relatively high levels of purity. In a preferred embodiment, combustible gas is discharged onto a substrate through a multi-zone flame facilitating the formation of nanoscale materials such as single and multi-wall nanotubes.
