A high precision method for length-based separation of carbon nanotubes using bio-conjugation, SDS-PAGE and silver staining. [PDF]
PLoS ONE, 2018 Parametric separation of carbon nanotubes, especially based on their length is a challenge for a number of nano-tech researchers. We demonstrate a method to combine bio-conjugation, SDS-PAGE, and silver staining in order to separate carbon nanotubes on ...

Ultraviolet photon absorption in single- and double-wall carbon nanotubes and peapods: Heating-induced phonon line broadening, wall coupling, and transformation [PDF]
, 2007 Ultraviolet photon absorption has been used to heat single- and double-wall carbon nanotubes and peapods in vacuum. By increasing the laser intensity up to 500 mW, a downshift and a broadening of the optical phonons are observed corresponding to a ...

Solitons in carbon nanotubes [PDF]
Physical Review B, 2000 The symmetries of spontaneous lattice distortions in carbon nanotubes are investigated. When the degeneracy of the ground states remains discrete, there are solitons or domain walls connecting the different symmetry broken vaccua. These solitons, similarly to the case of polyacetelene, are fractionally charged states.
