Abstract
Official abstract text for this publication.
Provided are carbon nanotubes that allow effective utilization of the insides thereof as-synthesized, without undergoing opening formation treatment. The provided carbon nanotubes have not undergone opening formation treatment and exhibit a convex upward shape in a t-plot obtained from an adsorption isotherm.
First claim
