Predictions of enhanced chemical reactivity at regions of local conformational strain on carbon nanotubes: kinky chemistry

Article Abstract:

Simulations that represent the consequences of conformational strain on the chemical reactivity of single-walled carbon nanotubes indicated a technique for substantially improving their reactivity locally by controlled deformations. The chemisorption of hydrogen atoms was predicted to be improved by as much as 1.6 eV at regions of high conformational deformation, suggesting that local reactivity will be substantially improved. Analysis of the local electronic density indicates the introduction of radical p orbital character to the sites that are locally deformed.

Isolation and characterization of fluorescent nanoparticles from pristine and oxidized electric arc-produced single-walled carbon nanotubes

Article Abstract:

Fluorescent nanoparticles were isolated from both pristine and nitric acid-oxidized commercially available carbon nanotubes that produced by an electric arc method. The pristine and oxidized carbon nanotube derived fluorescent nanoparticles exhibited a molecular-weight-dependent photoluminescence in the violet-blue and blue to yellowish-green ranges, respectively.

Organic solvent dispersions of single-walled carbon nanotubes: Towards solutions of pristine nanotubes

Article Abstract:

A systematic study has been performed in order to find an appropriate medium for solubilisation/dispersion of pristine single-walled carbon nanotubes. The room temperature solubility of single-walled carbon nanotubes in a variety of solvents finding a class of non-hydrogen-bonding Lewis basis that provide good solubility is investigated.
