unreacted

Depending on the fuel cell system design, some fuel might leave the system unreacted, constituting an additional loss.

Assuming that most of the "thermite" would have burned when set off, and only a fraction remained unreacted, then the amount of 0.1% of the total dust is astounding.

The paper ends with this sentence: “Based on these observations, we conclude that the red layer of the red/gray chips we have discovered in the WTC dust is active, unreacted thermitic material, incorporating nanotechnology, and is a highly energetic pyrotechnic or explosive material.”

One particularly unusual finding in this research article was that the percentage of "red/gray chips" of supposedly "unreacted thermite" amounted to approximately 0.1% of the total mass of the collected dust.

The technology may be immature -- e.g. the fuel (purity) grade is barely good for an explosion, but far from the optimum energy of a successful test (the consequence of this case would be dreadful for environmentalist, as a lot of unreacted nuke materials might have been left in the tunnel)

After each step the desired product must be separated from by-products and unreacted starting material and this takes time and involves loss of the product.
