Is the scientific manuscript "Active Thermitic Material Discovered in Dust from the 9/11WTC" valid

I wasnt ignorant of that claim about hematite , the XEDS spectra of hematite had Fe2+ and Fe3+ iron peaks , why im not sure.Please englighten us. Nevertheless its not important to the debate in hand the composition of hematite.Before september of 2002 were you or other scientists actively making nanothermite ? Im not well qualified enough to answer that question please email the authors of the paper with any concerns. Well i havent shifted the goal posts because we are not making iron spheres in a laboratory , how were iron spheres with that chemical signature produced by heating them to 440 c ? If you are a chemist you might have the answer , please englighten us. They took these red gray chips and heated them to 440c in normal air which undergoed exothermic reaction causing the formation of iron rich spheres,they did not heat in CO ."Fig. (21). Spheroid found in post-DSC residue showing iron-rich sphere and the corresponding XEDS spectrum. The carbon peak must be considered indeterminate here since this sample was flashed with a thin carbon layer in order to preclude charging under the electron beam." " A conventional quantitative analysis routine was used to estimate the elemental contents. In the case of this iron-rich spheroid, the iron content exceeds the oxygen content by approximately a factor of two, so substantial elemental iron must be present. This result was repeated in other iron-rich spheroids in the post-DSC sample as well as in spots in the residue which did not form into spheres. Spheroids were observed with Fe:O ratios up to approximately 4:1. Other iron-rich spheres were found in the post-DSC residue which contained iron along with aluminum and oxygen (see Discussion section). That thermitic reactions from the red/gray chips have indeed occurred in the DSC (rising temperature method of ignition) is confirmed by the combined observation of 1) highly energetic reactions occurring at approximately 430 ° C, 2) iron-rich sphere formation so that the product must have been sufficiently hot to be molten (over 1400 ° C for iron and iron oxide), 3) spheres, spheroids and nonspheroidal residues in which the iron content exceeds the oxygen content. Significant elemental iron is now present as expected from the thermitic reduction-oxidation reaction of aluminum and iron oxide. The evidence for active, highly energetic thermitic material in the WTC dust is compelling" response to second part "XEDS maps were acquired from the swollen red material at a beam energy of 10 kV, in order to determine the locations of various elements following the MEK treatment. The data shown in Fig. (15 ) illustrate regions where iron, aluminum and silicon are concentrated. Furthermore, the data indicate that wherever silicon or iron is concentrated, oxygen is also concentrated. On the other hand, there also exist regions where the aluminum is concentrated but where the Focusing the electron beam on a region rich in silicon, located in Fig. (15e ), we find silicon and oxygen and very little else (Fig. 16 ). Evidently the solvent has disrupted the matrix holding the various particles, allowing some migration and separation of the components. This is a significant result for it means that the aluminum and silicon are not bound chemically. The next XEDS spectrum (Fig. 17 ) was acquired from a region that showed a high concentration of aluminum. Using a conventional quantification routine, it was found that the aluminum significantly exceeded the oxygen present (approximately a 3:1 ratio). Thus, while some of the aluminum may be oxidized, there is insufficient oxygen present to account for all of the aluminum; some of the aluminum must therefore exist in elemental form in the red material. This is an important result. Aluminum particles are covered with a layer of aluminum oxide irrespective of size, thus it is reasonable to find a significant oxygen content with the aluminum, given the very high surface area to volume ratio of these very fine particles."
