The Army report is a little thin on the science end, so I went looking for pictures, which led me to this whole superlubricity subculture. Looks like nano-technology is expanding beyond microchips.

|Simulated superlubricity, a condition of extremely low friction. In the center is a graphene sheet (red) wrapping around a particle of another material (ochre? yellow? puke?). It does this by itself, just by being in the same place. Below we have an undisturbed sheet of graphene (green). Above we have some unknown material (gray).|
