Superlubricant

The poor lubricity means that the fuel flow must be dosed with a superlubricant and herein lies the root of the problem with naphtha firing.

Adhesives or superlubricants liberally applied on seaports, air base runways, highway intersections, steep railway grades, key bridges, and other bottlenecks could impede enemy military traffic or bring it to a standstill.

Figure 19 compares the two AES spectra, which show clearly the absence of oxygen and carbon on the outer surfaces of the wear scars of the superlubricant MoS₂, in contrast to the commercial coating which contained both carbon and oxygen.

Slippery foam is more promising — researchers still consider the superlubricant a viable mechanism for putting a railyard, dock, airstrip, or bridge out of commission temporarily without permanently destroying it.
