Investigating properties of nanotubes at high temperature.
A quantitative understanding of the strength of carbon nanotubes is important for the development of nanocomposites and other nanomaterials. However, there is still insufficient direct experimental data to validate theoretical predictions of the mechanical properties of carbon nanotubes. The role of kinks in carbon nanotube deformation is of particular...
