3. Conclusion and outlook

This paper deals with dissipation phenomena and noise associated with rigid nanostructures undergoing pure translational or elastic motion and bending deformation.

These dissipation phenomena are a relatively complex subject that covers a wide range of disciplines in physics. We have seen that viscous damping is strongly influenced by the scale effect. The rarefaction of the surrounding gas must therefore be taken into account. The calculations are not trivial and generally require knowledge of statistical and molecular physics, along with a solid foundation in numerical simulation. Monte Carlo simulation is a typical example. Furthermore, dissipation calculations relating to nanobeams show us that acoustic coupling effects (dissipation due to the support) or thermal coupling effects (thermoelastic dissipation) must be considered as first-order effects.
