Papers by Keyword: Metallofullerenes

Abstract: Endohedral metallofullerenes were prepared by DC arc discharge method with yttrium oxide and yttrium-nickel alloy as metal source, respectively. Mass spectroscopy and high-performance liquid chromatography analyses evidence that yttrium-nickel alloy has advantages over yttrium oxide in higher yield of soot, more species and higher yield of soluble metallofullerenes.

Abstract: In this study, we investigate the internal mechanics for a two-state memory device,comprising a charged metallofullerene which is located inside a closed carbon nanotube.Assuming the Lennard-Jones interaction energy and the continuum approximation, the metallofullerenehas two symmetrically placed equal minimum energy positions. On one side theencapsulated metallofullerene represents the zero information state and by applying an externalelectrical field, the metallofullerene can be made to overcome the energy barrier of thenanotube, and pass from one end of the tube to the other, where the metallofullerene thenrepresents the one information state.
