Elastic and Fracture Properties of Single Walled Pentagraphene Nanotubes
J. M. De Sousa, A. L. Aguiar, E. C. Girão +3
Membranes of carbon allotropes comprised solely of densely packed pentagonal rings, known as pentagraphene, exhibit negative Poisson's ratio (auxetic behavior) and a bandgap of $3.…
Elastic Properties of Graphyne-based Nanotubes
J. M. De Sousa, R. A. Bizao, V. P. Sousa Filho +6
Graphyne nanotubes (GNTs) are nanostructures obtained from rolled up graphyne sheets, in the same way carbon nanotubes (CNTs) are obtained from graphene ones. Graphynes are 2D carb…
Torsional 'Superplasticity' of Graphyne Nanotubes
Jose M. de Sousa, Gustavo Brunetto, Vitor R. Coluci +1
Graphyne is a planar two-dimensional carbon allotrope formed by atoms in sp, sp2, and sp3 hybridized states. Topologically graphyne nanotubes (GNTs) can be considered as cylindrica…
Thermophoretically Driven Carbon Nanotube Oscillators
V. R. Coluci, V. S. Timóteo, D. S. Galvão
The behavior of a nanodevice based upon double-walled carbon nanotube oscillators driven by periodically applied thermal gradients (7 and 17 K/nm) is investigated by numerical calc…
Rotational dynamics and polymerization of C in C-cubane crystals: A molecular dynamics study
Vitor R. Coluci, Fernando Sato, Scheila F. Braga +2
We report classical and tight-binding molecular dynamics simulations of the C fullerene and cubane molecular crystal in order to investigate intermolecular dynamics and poly…
Modeling the Auxetic Transition for Carbon Nanotube Sheets
Vitor R. Coluci, Lee J. Hall, Mikhail E. Kozlov +4
A simple model is developed to predict the complex mechanical properties of carbon nanotube sheets (buckypaper) [Hall \textit{et al.}, \textit{Science} \textbf{320} 504 (2008)]. Fa…
