Lubricating nanoparticles: The effect of doping semiconductor hollow closed-fullerene-like nanoparticles of MoS2 and WS2 has been overlooked to date. Rhenium doping of these nanoparticles leads to a marked increase in the nanoparticle's conductivity, reduced agglomeration, and a great reduction in friction and wear (see picture) that approaches superlubricity.
