Oligodeoxyribonucleotide Association with Single-Walled Carbon Nanotubes
02 Aug 2007 | | Contributor(s):: Jennifer McDonald
Commercially available single-walled carbon nanotubes (SWCNTs) tend to aggregate as ropes and bundles during production making them of little use in many scientific and industrial applications. An effective technique for dispersing and solubilizing SWCNTs is required to fully utilize their unique...

Orbital Mediated Tunneling in a New Unimolecular Rectifier
25 May 2007 | | Contributor(s):: Robert Metzger, NCN at Northwestern University
In 1997 we showed that hexadecylquinolinium tricyanoquinodimethanide is a unimolecular rectifier, by scanning tunneling microscopy and also as a Langmuir-Blodgett (LB) monolayer, sandwiched between Al electrodes. We have now seen rectification in a new molecule: this rectification can be followed...
