Nanofibers (IMAGE) North Carolina State University Caption Images of carbon nanofibers grown from nickel nanoparticle catalysts: (left) without removing the ligands and (right) after removing the ligands from the nanoparticles before nanofiber growth. Note how the nanofibers grown from nanoparticles with ligands are more uniform in diameter and distribution.
