摘要
•Atomistic simulations of size effect on octadecanoic acid.•The limited sizes of nanowire forms reduce the low frequency atom vibration.•The nanochain forms exhibit more phonon scattering by high level phonon mismatch.•The biggest thermal conductivity value occurs for bulk while the smallest for nanochain.
