A scientific paper published in a respectable peer-reviewed journal, The Open Chemical Physics Journal, entitled"Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe" provides indisputable evidence that a highly engineered explosive called nano-thermite was found in the dust of all three buildings that came down on 9/11 2001 in New York city.

This advanced explosive incorporating nanotechnology is only available to sophisticated military labs.

The researchers have discovered distinctive red/gray chips in all the samples they have studied of the dust produced by the destruction of the World Trade Center . Examination of four of these samples, collected from separate sites, is reported in their paper. These red/gray chips show marked similarities in all four samples. One sample was collected by a Manhattan resident about ten minutes after the collapse of the second WTC Tower , two the next day, and a fourth about a week later. The properties of these chips were analyzed using optical microscopy, scanning electron microscopy (SEM), X-ray energy dispersive spectroscopy (XEDS), and differential scanning calorimetry (DSC).

The red material contains grains approximately 100 nm across which are largely iron oxide, while aluminum is contained in tiny plate-like structures. Separation of components using methyl ethyl ketone demonstrated that elemental aluminum is present.

The iron oxide and aluminum are intimately mixed in the red material. When ignited in a DSC device the chips exhibit large but narrow exotherms occurring at approximately 430 °C, far below the normal ignition temperature for conventional thermite.

Numerous iron-rich spheres are clearly observed in the residue following the ignition of these peculiar red/gray chips. The red portion of these chips is found to be an unreacted thermitic material and highly energetic.
