Separating Single-Walled Carbon Nanotubes by Length

Rauwald U., Schmidt D.J., Hauge R.H., Smalley R.E., Ziegler K.J., University of Florida, US

Single-walled carbon nanotubes (SWNTs) have received great attention because of their unique electronic and mechanical properties combined with their chemical stability. Typically, SWNTs are microns in length; however, intermediate lengths between small spheroidal fullerenes and [...]

Cutting Fluorinated/Ozonated Single-Walled Carbon Nanotubes by Pyrolysis

Chen Z., Gu Z., Ziegler K., Chan C.K., Shaver J., Hauge R.H., Smalley R.E., Rice University, US

Fluorinated/ozonated Single-Walled Carbon Nanotubes (SWNTs) was found to have been cut to short length by Pyrolysis and/or piranha treatment. Large scale cutting of SWNTs would lead to novel applications of nanotubes in microelectronics, biological imaging [...]

Cutting, Solubilizing and Size-Sorting of Single-Wall Carbon Nanotubes

Gu Z., Peng H., Cratty J., Hauge R.H., Smalley R.E., Margrave J.L., Rice University, US

The fluorination of purified HiPco single-wall carbon nanotubes (SWNTs) to a stoichiometry CFx (x ≤ 0.2) followed by pyrolysis of the partially fluorinated SWNTs up to 1000 oC was found to have cut the nanotubes [...]
