From: Conditions for escape of a rotor in a rotary nanobearing from short triple-wall nanotubes

Curves of ω 1 and the snapshots of the nanobearing from TWNT (17, 11)/(20, 20)/(25, 25) when driven by Rotor2. (a) ω 2 = 200 GHz. (b) ω 2 is nearby the critical value, i.e., 128 GHz. (c) ω 2 > 128 GHz (the values appear in bi-section process). (d) Rotor1 shows non-coaxial with Stator.
