Nice, but not necessary
Wildbear, yes it would be interesting to see whether the red chips would ignite in the same way in an oxygen-free atmosphere. However, if they did not, it would prove nothing against the Active Thermitic Material hypothesis, as oxygen was present in the towers.
The important criterion regarding the DSC test is that the product is globular iron, hence previously molten. There is no way that the combustion of organic material in air can produce a temperature high enough to produce molten iron.
For those promoting "thermitic paint", the responsibility is theirs to find a sample of such material and to show that it had been applied in large scale in the towers. A theory without evidence is just a distraction.
