Our research group members have been pioneers in the synthesis, characterization and development of carbon nanotubes and their engineered structures ever since the discovery of this material at NEC labs in 1991. Prof. Ajayan worked with Sumio Iijima and Thomas Ebbesen during the early days of carbon nanotubes research. The group has been responsible for various milestones in the development of carbon nanotubes. Our present interests are in the engineering of meso- and macro-scale architectures of carbon nanotubes and their hybrids and explore applications.
