Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Carbon nanotubes (CNTs) have received the attention of researchers for the past 25 years. It is one of the most investigative material in the history of Nanoscience and mainly responsible for current Nanotechnology boom. This chapter describes the various techniques of synthesis of CNTs such as arc discharge, laser ablation and chemical vapor deposition. Special techniques like use of liquid solution in arc discharge, lithographic techniques, solar, electrolysis and hydrothermal for CNTs synthesis are also included. The chapter also discusses the mechanism proposed for the development of carbon nanotubes in these methods and summarizes the removal of impurities from these synthesized CNTs by chemical, physical, and multi-steps purifications.
