On the basis of these and other observations, the team concluded 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."4
The article's first-named author, Dr. Niels Harrit a University of Copenhagen chemistry professor who specializes in nano-chemistry5 explained on Danish TV2 News:
"Thermite itself dates back to 1893. It is a mixture of aluminum and rust-powder, which react to create intense heat. The reaction produces iron, heated to 2500 degrees Centigrade. This can be used to do welding. It can also be used to melt other iron.
"So in nano-thermite, this powder from 1893 is reduced to tiny particles, perfectly mixed. When these react, the intense heat develops much more quickly. Nano-thermite can be mixed with additives to give off intense heat, or serve as a very effective explosive. It contains more energy than dynamite, and can be used as rocket fuel.
"You cannot fudge this kind of science. We have found it: unreacted thermite."6
What was the significance of this sophisticated material?
Reported Evidence that Nano-thermite is a Military Substance
In a German interview in May 2009, Dr. Harrit said: "There are no experts on nano-thermite without connections to the military". This stuff has only been prepared under military contracts in the USA and probably in bigger allied countries. This is secret military research"It was not prepared in a cave in Afghanistan."7
