? Carbon nanotubes have been produced by catalytic decomposition of acetylene on iron nanoparticles. Electron microscopes were used to examine the morphology and structure of the nanotubes. Experimental results show that the growth of branched carbon filaments from the wall of the nanotubes may be possible. The mechanism of the kinks formed on carbon nanotubes was studied. 
