Improved Selectivity In Making Metallic Carbon Nanotubes
A new way of preparing single-walled carbon nanotubes allows chemists to control the tubes’ chirality, which is the property that renders their conductivity behavior either semiconducting or metallike (Science 2009, 326, 116). Standard nanotube synthesis methods usually produce a mixture of semiconducting and metallic tubes, which are difficult to separate. A team led by Avetik R. Harutyunyan of the Honda Research Institute USA, in Columbus, Ohio, used iron nanocatalysts deposited onto a SiO2/Si . . .
