Controls of hole opening in single-wall carbon nanotubes and single-wall carbon nanohorns using oxygen

Article Abstract:

A study is conducted to show that C-dust-free hole-opening in single-walled carbon nanohorns (SWNHs) and heat-treated single-walled carbon nanotubes (SWNTs) could be easily achieves using slow combustion. The results reveal that the quantity of C-dust was greatly reduced by slow combustion using a low-temperature-increase and a low oxygen concentration.

Quantum effects on hydrogen adsorption in internal nanospaces of single-wall carbon nanohorns

Article Abstract:

Hydrogen adsorption isotherms in single-wall carbon nanohorns (SWNHs) were measured at 20 K. The pore volume from hydrogen adsorption was compared with that from nitrogen adsorption at 77 K to determine the density of confined hydrogen in the internal space of SWNHs.
