Application of an electrostatically actuated cantilevered carbon nanotube with an attached mass as a bio-mass sensor
TL;DR: In this article, the relationship between the resonant frequency, dynamic pull-in voltage at the resonance frequency shift, and the attached mass is established by using the nonlocal Euler-Bernoulli beam theory.

Exceptionally high Young's modulus observed for individual carbon nanotubes
TL;DR: In this article, the amplitude of the intrinsic thermal vibrations of isolated carbon nanotubes was measured in the transmission electron microscopy (TEM) and it was shown that they have exceptionally high Young's moduli, in the terapascal (TPa) range.

Nanobeam mechanics: Elasticity, strength, and toughness of nanorods and nanotubes
TL;DR: In this paper, the Young's modulus, strength, and toughness of nanostructures are evaluated using an atomic force microscopy (AFM) approach. And the results showed that the strength of the SiC NRs were substantially greater than those found previously for larger SiC structures, and they approach theoretical values.

Electrostatic deflections and electromechanical resonances of carbon nanotubes
TL;DR: The methods developed here have been applied to a nanobalance for nanoscopic particles and also to a Kelvin probe based on nanotubes, which indicates a crossover from a uniform elastic mode to an elastic mode that involves wavelike distortions in the nanotube.
