    • Purification of the ARC-derived material was done in a two-step process: (i) selective oxidation in dry air for 30 min at 450°C and (ii) refluxing in 4 M HCl at 120°C for 24 hours.

    • note
    • Recently, a broad peak in S(T), observed below 100 K and superimposed on a linear T background, has been attributed to an additional contribution from phonon drag (11, 17). Because our measurements in this study were made at 500 K, we ignore a phonon drag contribution that is a low-temperature effect.

    • The (10,0) tube is semiconducting and has a diameter of 7.83 Å. It is sufficiently small to facilitate the simulation of a large number of scattering events required for statistical analysis.

    • This was done by scaling the velocity of the carbon atoms at the tube ends to zero at each trajectory time step. In this way, energy flowing in the tube axial direction was adsorbed, but not energy that flows in the tube radial or circumferential directions.

    • -1. The short length of the nanotube which is clamped at the ends may upshift the squash-mode frequency relative to that obtained for an infinite tube.

    • note
    • We also found that the slopes of theoretical lines of the average tube energy and the maximum radial displacement as a function of the colliding mass decrease with time.
