A dendrimer-based Co-32 nanocluster: Synthesis and application in diameter-controlled growth of single-walled carbon nanotubes

We report the synthesis and characterization of a dendrimer-based Co-32 nanocluster molecule and its use as uniform-size catalytic seed for diameter-controlled growth of single-walled carbon nanotubes. (c) 2005 Elsevier Ltd. All rights reserved.
