NASA Applications of Molecular Nanotechnology

Laboratories throughout the world are rapidly gaining atomically precise control over matter. As this control extends to an ever wider variety of materials, processes and devices, opportunities for applications relevant to NASA's missions will be created. This document surveys a number of future molecular nanotechnology capabilities of aerospace interest. Computer applications, launch vehicle improvements, and active materials appear to be of particular interest. We also list a number of applications for each of NASA's enterprises. If advanced molecular nanotechnology can be developed, almost all of NASA's endeavors will be radically improved. In particular, a sufficiently advanced molecular nanotechnology can arguably bring large scale space colonization within our grasp.

Chemical Storage of Data

We investigate the possibility of storing data using H and F on a polymer to signify 0 and 1 bits. We show that the difference between the B-F and B-H interaction energies for either C5H5B or C3H3N2B is only slightly larger than the variation in B-F interaction energy with type of neighboring atoms. Pyridine (C5H5N) and (CH3)3P=O have a much larger difference in the H and F interaction energies. (CH3)3P=O may be better suited as a surface probe, because the interaction with neighboring data sites should be smaller.
