DESCRIPTION:The miniaturization of mechanical devices has evolved to the p
 oint that microelectromechanical systems (MEMS) are now in widespread use.
  While _useful_ nano-mechanical systems have not yet been constructed\, so
 me prototype devices with sub-micron dimensions have been made and it seem
 s unlikely that the ultimate lower size limit of functional machines has\,
  on the micron scale\, already been reached. In this seminar I will discus
 s some of the issues that arise when the dimensions of a mechanical device
  approach the nanometer length scale. I will provide some examples from mo
 lecular dynamics simulations of simple carbon-nanotube-based mechanical sy
 stems to illustrate the host of problems that will arise in the design of 
 deterministic nanomachines.\n\n
