Exotic behavior when mechanical devices reach the nanoscale

Mechanical resonators are extensively used in high-tech industry, to mark time in electronic components, and to stabilize radio transmissions. Most mechanical resonators damp (slow down) in a well-understood linear manner, but ground-breaking work has now shown that resonators formed from nanoscale graphene and carbon nanotubes exhibit nonlinear damping, opening up exciting possibilities for super-sensitive detectors of force or mass.
