Single-walled carbon nanotubes (SWCNTs) are seamless cylindrical tubes consisting of carbon atoms with diameters ranging from less than one nanometer to a few nanometers. The arrangement of carbon atoms in a SWCNT is uniquely specified by using a pair of integers (n,m) referred to as the chiral indices. While the detailed structures, such as a carbon–carbon bond length, should be important, they have...
In situ transmission electron microscope (TEM) observation has become a fairly powerful characterization method to uniquely provide the real-time information on the dynamics and kinetics of physical and chemical transformations at the nanometer scale. Here, we report a development of a high-temperature-compatible specimen heating holder equipped with a micro-sized carbon nanotube (CNT) network heater...
Metal catalyst-free mist flow chemical vapor deposition (CVD) growth of single-walled carbon nanotubes (SWCNTs) with C60 fullerenes has been investigated by using an aqueous colloidal C60 solution. Under the optimum reaction condition, relatively uniform SWCNTs with a mean diameter of 1.28nm can be synthesized without any treatments of C60 prior to CVD. Cap opening, nucleation and the growth of SWCNTs...
