Query: Radial deformation measurements of isolated pairs of single-walled
  carbon nanotubes   Interactions between atoms of bound single-walled carbon nanotubes (SWNTs)
are known to cause measurable distortion to the tube's original circular
cross-section frame. High-resolution transmission electron microscope (TEM)
investigation was used here to directly image and verify these radial
deformations. The data presented here provide, for the first time, direct
measurements of the deformations due to the interactions between isolated pairs
of nanotubes. The deformation data is compared to previously reported
experimental and simulation results.
