Gaseous density layering within carbon nanotubes: An analytic model

Growing Carbon Nanotubes within Boron Nitride Nanotubes

The controlled synthesis and growth of carbon nanotubes (CNTs) has been a long standing challenge in the fabrication of carbon based materials for electronic applications. Due to the sensitivity to small changes in their structure, the successful integration of CNTs on electronic devices is conditioned to the preservation of the graphitic network of single and multiwalled nanotubes from externa...

Azafullerenes encapsulated within single-walled carbon nanotubes.

Methods of insertion of azafullerenes in single-walled carbon nanotubes (SWNTs) at different temperatures were investigated, while the effects of the conditions applied on the structure of azafullerene-based peapods, namely, C59N@SWNTs, were explored. Morphological characteristics of C59N@SWNTs were assessed and evaluated by means of high-resolution transmission electron microscopy (HR-TEM). Pa...

Universal Density of States for Carbon Nanotubes

The density of states in the vicinity of the Fermi level of single-wall carbon nanotubes can be expressed in terms of a universal relationship that depends only on whether the nanotube is metallic or semiconducting. We compare the predictions of this approximate relationship with densities of states calculated using first-principles band structure results. These comparisons show that this appro...

Carbon nanotubes: An explosive thrust for nanotubes.

Nonlocal Flügge shell model for the axial buckling of single-walled Carbon nanotubes: An analytical approach

In this paper, the stability characteristics of single-walled carbon nanotubes (SWCNTs) under the action of axial load are investigated. To this end, a nonlocal Flügge shell model is developed to accommodate the small length scale effects. The analytical Rayleigh-Ritz method with beam functions is applied to the variational statement derived from the Flügge-type buckling equations. Molecular dy...
