Molecular bearings
Molecular manufacturing systems will make extensive use of molecular bearings to enable smooth, low-friction motion of nanomechanical parts.
Topics:
Bearings play a crucial role in many sorts of machinery
A shaft in a sleeve can form a rotary bearing
Bearings can be stable despite attractive interactions between their surfaces
Phonon drag in sleeve bearings can be orders of magnitude smaller than viscous drag in liquids
Sleeve bearings have been designed and modeled in atomic detail
PDB files can describe molecular structures in atomic detail
