Encapsulated ball bearings for rotary micro machines
We report on the first encapsulated rotary ball bearing mechanism using silicon microfabrication and stainless steel balls. The method of capturing stainless steel balls within a silicon race to support a silicon rotor both axially and radially is developed for rotary micro machines and MEMS ball bearing tribology studies. Initial demonstrations show speeds up to 6.8 krpm without lubrication, w...

متن کاملApproaches to rotary molecular motors*
Interest has recently intensified in the search for molecular motors and actuators capable of delivering useful work to nanodevices under the control of electrochemical or photochemical power sources. While many of these man-made molecular machines are designed to deliver rectilinear motion, very few are proposed for the controlled delivery of rotary motion on the time scale characteristic of i...
متن کاملMolecular Machines
The use of EM and image analysis techniques, particularly the single particle methodology, has opened the door to the structural characterization of large protein complexes in the megadalton range. This review covers the basic principles of single particle EM and recent examples of its application to the study of large molecular machines in the eukaryotic cell. These examples will give the read...
متن کاملMolecular machines.
Molecular machines are tiny energy conversion devices on the molecular-size scale. Whether naturally occurring or synthetic, these machines are generally more efficient than their macroscale counterparts. They have their own mechanochemistry, dynamics, workspace, and usability and are composed of nature's building blocks: namely proteins, DNA, and other compounds, built atom by atom. With moder...
