Using the nitrene reaction, two individual single-walled carbon nanotubes can be covalently connected inducing only few defects to the nanotube sidewall. With this functionalization method nanotubes can be linked within a bundle as well as between bundles. For systematic investigations, a series of linker molecules of different lengths were synthesized. By filtering and drying, a buckypaper of linked...
In this contribution we provide an overview of our recent work on the mechanical and electronic properties of carbon and boron-nitride (BN) nanotubes, which are of key relevance to practical applications and to our present understanding of low-dimensional structures. On the mechanical properties we look at the nanotube axial stiffness, bending and torsion dynamics. We found that chiral tubes exhibit...
A Raman scattering characterization is reported that confirms the preparation of single wall carbon nanotubes (SWNT) by the solar energy route. The results are presented for samples synthesized with various catalysts—mixtures of Ni and Co (Y, La)—and compared to those obtained from electric arc discharge or laser ablation. In the light of the calculations of the vibrational spectra of SWNT by Eklund...
Co-evaporation of carbon, in the presence of helium with some other element as catalyst, yields interesting new molecules of the fullerene family which have tubular morphologies with a cross-section at the nanoscale but lengths at the macroscale. In particular, using Ni or Co based mixtures as catalyst with the electric arc technique, one obtains single wall carbon nanotubes in large quantities, with...
