Split peas : Nanopeapods consisting of highly ordered, wavy NiO nanopods embedded with equally spaced Pt nanopeas were fabricated by the oxidation of multisegmented Ni/Pt nanowires at low temperatures. The Ni/Pt interface is an efficient platform for enhancing the outward diffusion of Ni during oxidation and for manipulating the nucleation of vacancies in Ni, which intrinsically behaves in an uncontrolled manner.
