Structure transformation of T-carbon nanowires from MWCNTs. HRTEM images of a shortened MWCNTs (insets show the structure and FFT pattern of pristine MWCNTs) (scale bar = 20 nm) and b carbon nanowire produced from laser irradiation (inset: low magnification, scale bar = 5 nm). FFT patterns of c the nanowire corresponding to b (scale bar = 5 nm⁻¹), and d another nanowire (scale bar = 2 nm⁻¹). e EELS spectrum corresponding to b after subtraction of carbon film background
