摘要：

Possible mechanisms of carbon spheric nanoparticle formation are discussed. The growth mechanisms of nanoparticles with isospiral structures are not easily compatible with several experimental facts. The model of shell-by-shell growth of nanoparticles is not confirmed by our molecular dynamics simulation. We suppose that nanoparticles with shell structures arise from liquid cluster crystallization. We propose a new explanation for the origin of this liquid cluster: it is a result of melting of graphitic nanocrystals evaporated from electrodes.
