Carbon nanotubes (CNTs) are synthesized utilizing novel, electrically-enhanced, oxy-fuel flame-based, catalytic chemical vapor deposition methods. The program integrates synthesis, in-situ laser-based diagnosis, and subsequent materials characterization of CNTs to optimize CNT production at high rates with prescribed characteristics (e.g. single- or multi-walled, diameter, helicity). Such a paradigm allows not only for detailed fundamental study of the mechanisms involved in CNT formation and growth but also for the active control of those basic processes, so that CNTs with tailored physical properties can be produced in large quantities with high purity.
