Macpherson and Unwin and co-workers Challenge the Current Consensus on the Electrochemical Properties of Nanotubes as featured in "Chemistry World" http://www.rsc.org/chemistryworld/2012/06/challenging-consensus-nanotube-electrochemistry and Chemical Communications http://pubs.rsc.org/en/content/articlelanding/2012/cc/c2cc32890a.

For more information see "Electrochemistry at Carbon Nanotube Forests: Sidewalls and Closed Ends Allow Fast Electron Transfer; The electrochemical properties of the closed ends and sidewalls of pristine carbon nanotube forests are investigated directly using a nanopipet electrochemical cell. Both are shown to promote fast electron transfer, without any activation or processing of the carbon nanotube material required, in contrast to the current model in the literature." Chem.
