Contributed Papers from MSC to 7th Foresight Conference on Molecular Nanotechnology.
Molecular mechanics and molecular dynamics studies are carried out at the MSC by Tahir Cagin, Guaghua Gao, Jinsong Hu and W. A. Goddard III on the Molecular Planetary Gear proposed by R. Merkle and E. Drexler. These all atom simulations employed Dreiding Parameters for the interactions.

Over 12.0 picoseconds simulation, the input unit completes one full cycle and the output unit completes almost a half cycle and the rail completes a quarter cycle. Over the run the initial angular kinetic energy partially dissipates through conversion into thermal energy via atomic collisions

The two movies represent the same dynamics trajectory calculation over its full duration, but the second includes more intermediate frames.
The MPEG movies were generated by Jim Kendall from a dynamics trajectory run by Tahir Cagin. Cerius2 molecular dynamics software was used to calculate the trajectory.
