We know from the WoR on Aura that dust reacts to aura and that semblance is just the specialised manifestation of aura for a certain person.

So Blake using dust bullets to modify her clones could simply be her shooting the cartridge into it. As for Nora, she could easily have chanelled her semblance into the grenades to maximise their destruction area. You know, like Weiss used her glyphs to shape the ice.
