Synthesis of Multi-walled Carbon Nanotubes by Plasma Enhanced Microwave Cvd Using Colloidal Form of Iron Oxide as a Catalyst
(Oklahoma State University, 2005-05-01)
Carbon nanotubes (CNTs) were discovered in 1991 by Sumio Iijima of NEC Corporation, Japan. They are rolled up sheets of graphene and have structure resembling that of an elongated fullerene molecule. Because of their ...
Experimental investigation on the synthesis of carbon nanotubes (CNTs) by arc-discharge method using a MIG welder
(Oklahoma State University, 2005-12-01)
Carbon nanotubes (CNT) are obtained by vaporizing graphite in an inert atmosphere using the arc-discharge method. Helium is found to be a favorable buffer gas for the synthesis of MWNTs compared to argon. Maximum yield of ...
