Sorting and transmission electron microscopy analysis of single or double wall carbon nanotubes [PDF]

open access: yes, 2009
On the basis of the recent progress on the sorting of carbon nanotubes’ structure with respect to their diameter or number of walls, we investigate by transmission electron microscopy the sorting efficiency, with a comparison with optical absorption ...

Effect of hydroxylated carbon nanotubes on the thermal and electrical properties of derived epoxy composite materials

open access: yesResults in Physics, 2020
Carbon nanotubes are efficient thermal conductors and exhibit unique electrical properties. What is not entirely clear, however, is how to effectively transfer the carbon nanotube's unique attributes exhibited at the nanoscale to the macroscale.

Structural selective charge transfer in iodine-doped carbon nanotubes [PDF]

open access: yes, 2006
We have investigated iodine intercalated carbon nanostructures by extended X-ray absorption fine structure (EXAFS) and Raman spectroscopies. We discuss here the charge transfer and the iodine–carbon interaction as a function of the carbon nanostructures (

Carbon Nanotube Actuators

open access: yesScience, 1999
Electromechanical actuators based on sheets of single-walled carbon nanotubes were shown to generate higher stresses than natural muscle and higher strains than high-modulus ferroelectrics. Like natural muscles, the macroscopic actuators are assemblies of billions of individual nanoscale actuators.
