"An excellent, concise, knockdown counterargument to the 9/11 Truthers’ “microspheres” thermite propaganda" says Jonathan Kay, managing editor of Canada's National Post and author of "Among The Truthers"
Found this posted on a group called New Mexicans for Science and Reason …
Hi Niels, thought you should see this, This was published on a blog (Among The Truthers) May 11, 2012 - by National post managing editor and author of the book "Among The Truthers" Jonathan Kay. Best Regards Doug
Hi Doug This is totally ridiculous, and the source, Dave Thomas of New Mexico, as well. I had a healthy laugh. many regards from Copenhagen

is a physicist and mathematician, mostly known for his writings and research on the paranormal (such as UFO sightings in Roswell, New Mexico and Aztec, New Mexico, as well as finding codings in other texts that dispute the credibility of the Bible Code). Thomas is currently president of New Mexicans for Science and Reason and a past president of the New Mexico Academy of Science, and is also a Fellow of the Committee for Skeptical Inquiry.

Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe

We have discovered distinctive red/gray chips in all the samples we 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 this 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.
