Size-dependent nonlinear elastic scaling of multiwalled carbon nanotubes.
We characterize through large-scale simulations the nonlinear elastic response of multiwalled carbon nanotubes (MWCNTs) in torsion and bending. We identify a unified law consisting of two distinct power law regimes in the energy-deformation relation. This law encapsulates the complex mechanics of rippling and is described in terms of elastic constants, a critical length scale, and an anharmonic...
متن کاملNonlinear mechanical response and rippling of thick multiwalled carbon nanotubes.
The measured drop of the effective bending stiffness of multiwalled carbon nanotubes (MWCNTs) with increasing diameter is investigated by a generalized local quasicontinuum method. The previous hypothesis that this reduction is due to a rippling mode is confirmed by the calculations. The observed ripples result from a complex three-dimensional deformation similar to the Yoshimura buckling patte...
متن کاملNonlinear Vibration Analysis of Embedded Multiwalled Carbon Nanotubes in Thermal Environment
In this article, based on the Euler-Bernoulli beam theory, the large-amplitude vibration of multiwalled carbon nanotubes embedded in an elastic medium is investigated. The method of incremental harmonic balance is implemented to solve the set of governing nonlinear equations coupled via the van der Waals (vdW) interlayer force. The influences of number of tube walls, the elastic medium, nanotub...
متن کاملSize- and shape-dependent pleural translocation, deposition, fibrogenesis, and mesothelial proliferation by multiwalled carbon nanotubes
Multiwalled carbon nanotubes (MWCNT) have a fibrous structure similar to asbestos, raising concern that MWCNT exposure may lead to asbestos-like diseases. Previously we showed that MWCNT translocated from the lung alveoli into the pleural cavity and caused mesothelial proliferation and fibrosis in the visceral pleura. Multiwalled carbon nanotubes were not found in the parietal pleura, the initi...
متن کاملMultiwalled Carbon Nanotubes: Environmental Application
The high external surface area leads to a significant increase in the surface contact between the gaseous or liquid reactants and the active phase supported on this nanostructured host which is a prerequisite for its use as catalyst support, especially in liquid phase medium where diffusion rate is predominant [2]. Also, the strong interactions between the exposed prismatic planes and the depos...
