Abstract: | Catalytic nickel particles at the tips of carbon nanotubes grown under different physicochemical conditions are experimentally studied by high-energy electron diffraction. The spacings of the crystal lattice are determined. It is demonstrated that the nanoparticles consist of a supersaturated solid solution of carbon in nickel with an abnormally high carbon content. |
