I doubt I have the background knowledge to assess a chemistry paper.
But thermitic materials make no sense for the Twin Towers. If structural failure were to occur across a full cross-section, there’s no way they could not collapse. If an aircraft had failed to arrive, there’d be a tower full of thermite and detonation equipment, so it’d make more sense to dispense with any destructive materials and just let them burn, even if they didn’t collapse.
If the paper is right, the thermitic material presumably came from somewhere else. It would seem more likely that it was deliberately added to the dust; a psi-op to help protect the Saudi-jihadi-NATO collaboration.
