Of interest in that paper is the thermal conductivity measured.

For the carbon black for a ~100mm^2 area a value of ~0.033 C/W is proposed, and for a soldered joint a value of ~0.050 C/W is proposed.

Hard to say how that compares with goops like ShinEtsu, Arctic Silver or Cooling Flow as no commercial pastes were included in the testing.

Is AS3 worse than the carbon black mixture? I guess one would presume so, but where does it fit in? One would imagine that a micronised silver mixture would be substantially better than the graphite mixture which was measured at around 0.22C/W for a ~100mm^2 heat die.

Basically we need more testing on this.
