    • The cooling rate of helium downstream from the furnace exit was measured to be less than 4.0 × 103 K/s. For the quasistatic cooling of a 10 nm particle, the average energy transfer rate of 0.14 μeV per collision is required. This condition is well satisfied [8] in the present cooling procedure.

    • note
    • The average minor/major size ratio of the as-grown Dh particles larger than 7 nm was found to be ∼0.7 before annealing. The ratio increased up to 0.8-0.9 after annealing at 1173 K, while no population change was observed [see Figs. 2(a) and 2(b)]. The poor sphericity of the Dh particles was likely improved by the diffusion of surface atoms towards the surface energy reduction.
