Abstract
Ultralong carbon nanotubes can be formed by placing a secondary chamber within a reactor chamber to restrict a flow to provide a laminar flow. Inner shells can be successively extracted from multi-walled carbon nanotubes (MWNTs) such as by applying a lateral force to an elongated tubular sidewall at a location between its two ends. The extracted shells can have varying electrical and mechanical properties that can be used to create useful materials, electrical devices, and mechanical devices.
