Firstly, let me declare my position - that the three WTC towers could not have imploded on 9/11 without some method of controlled demolition. Originally, this was a view I found too incredible to countenance (argument from incredulity). Having given the topic much attention, I now find the official theory - that they were brought down by a combination of fire and damage impossible to sustain.
The question of how, seems somewhat academic to me. I'm more interested in who. Nevertheless, if to a reasonable degree of certainty the first question is answered, maybe more people will demand an answer to the second.
It's with that in mind that I approach the publication today of Active Thermitic Material Discovered in Dust from the 9/11 World Trade Center Catastrophe pp.7-31 (25) Authors: Niels H. Harrit, Jeffrey Farrer, Steven E. Jones, Kevin R. Ryan, Frank M. Legge, Daniel Farnsworth, Gregg Roberts, James R. Gourley, Bradley R. Larsen
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.

Additional to SPreston and godles's comments: - the answer, I'm afraid, is yes and no. Many (like godless) in the mainstream scientific and engineering community have: Architects & Engineers for 9/11 Truth, Journal of 9/11 Studies, Medical Professionals for 9/11 Truth, 660+ Engineers and Architects Question 9/11, 7 Senior Federal Engineers and Scientists Call for New 9/11 Investigation (PDF), etc.
Very many others are unaware of the issues, thanks to the mainstream media's incessant promotion of the official story and scrupulous censorship of information which challenges it.
Coupled with this, very few major scientific journals would dare put their heads above the parapet by publishing a theory that almost pre-supposed government complicity in the horrors of 9/11. In an ideal world, scientific merit would be the issue. In the real world, the panel will protect the political and financial well-being of its journal. When the stakes are this high, the peer review process is, to a large extent, a gatekeeper's charter.
Nevertheless, several other peer-reviewed papers that contradict the official accounts of 9/11 (as per the 9/11 Commission, NIST etc.) have already been published, but typically they received no mainstream publicity:

NIST's study into the destruction of the towers, it should be noted, was not peer-reviewed: “I wish that there would be a peer review of this... I think all the records that NIST has assembled should be archived. I would really like to see someone else take a look at what they’ve done; both structurally and from a fire point of view... I think the official conclusion that NIST arrived at is questionable,” Former Chief of NIST's Fire Science Division Calls for Independent Review of World Trade Center Investigation

If this were so clear cut how could it not merit a line on Drudge or on our Yahoo mail page?
First, let's be clear - this is not somebody "whipping it out" to sell a book. It was exhaustively peer-reviewed "with pages of comments by referees. The tough questions the reviewers raised led to months of further experiments. These studies added much to the paper, including observation and photographs of iron-aluminum rich spheres produced as the material is ignited in a Differential Scanning Calorimeter". Furthermore, (unlike most technical specialist journals) the Open Chemical Physics Journal is free access - see download link above.
I don't expect to see the major industry journals or popular science magazines covering this (for reasons stated) but as for the lack of internet news coverage - it was only published a few hours ago.
There are two camps for sure, but I don't think many realize how small the official camp is compared to the growing number of highly accredited engineers and scientists on the other side.
Many seem to assume that any scientist not actively engaged in criticising NIST must be tacitly acquiescing. Clearly this is an illogical assumption.
Although there are about 1.5 million engineers in the US, the same four who "investigated" the Oklahoma City Murray building bombing turn up six years later as the ASCE team on the WTC collapses. One of them (Corley) is also involved in the Weidlinger study on behalf of Silverstein (which arrives at a different theory about the cause of the collapses!). Two of them work on the Pentagon Building Report. Another 6 who work on the FEMA report become part of the NIST team. Apparently very few engineers were either required or willing to work on the government's investigation.
And, of course, FEMA and NIST are federal agencies, like the Bush appointed 9/11 Commission, with institutional conflicts of interest that guarantee a lack of independence.

The evidence in this case could only be debated by challenging it's provenance, but the scientific interpretation of the evidence can and should be rationally debated. That is a major purpose of publishing the paper - to invite the wider scientific community to scrutinise the findings.
Although NIST, at least in their public posture, never seriously considered a controlled demolition hypothesis, several of the key engineers involved in the investigation were better qualified in explosives technology than structural collapse analysis and NIST has a long-standing partnership with NASA for the development of new nano-thermites and has a long history of working with leaders in nano-thermite technology.
The Top Ten Connections Between NIST and Nano-Thermites
NIST have not provided an alternative explanation for the nano particle findings. Just as they dismissed the evidence (when pressed) of molten metal beneath the buildings, they have simply ignored it's existence. No dust samples analysed - no awkward evidence to hand wave away.
If you were trying, after the fact, to cover up the demolition of the towers by nano-thermites, you could not do better than select insiders with expertise in nano-thermites - maybe the same experts who provided the technology used in the crime. What better way to ensure incriminating evidence - unignited thermite, molten metal, countless reports of explosions, molten metal cascades pouring from the buildings, etc. - did not hamper a pre-defined conclusion?

First, it's common knowledge and well-documented that a thermite reaction occurs when molten
aluminium contacts iron oxide.
It's no surprise at all that there are products of thermite-like reactions in the WTC dust clouds.
A residue is a part of the actual explosive itself that does not combust and not a combination of chemicals and/or compounds which could potentially be recombined to form a pyrotechnic metal cutting/welding compound such as thermite.
Detonation (hyper-sonic combustion) residues are the unreacted pieces of the actual explosive compound itself which is left behind at the conclusion of each micro-reaction %100.00 of the time.
If any form of thermite had been used to cut the steel there would be tons of actual unreacted thermite in the dust, you wouldn't need to reverse-engineer thermite from it's products as this paper attempts to do.
The unexploded thermite would have completely mixed throughout the profile of the dust cloud that fell all around the attack site, absorbed by plants including grass lawns, trees and lichens. Easily detectable amounts of the speculated multi-tons of pyrotechnic compound would still be present today in the lichen's branches, accumulated at the base of the roots of trees and chemically combined with the soil beneath any grass and in the sludge at the bottoms of lakes and ponds. As these materials were washed down in to the sewerage system, the pyrotechnic particles would form a layer of scum along the concrete walls in the sewerage complex at the level the water was at when it flowed in, and form a layer of silt which would still be present today and which will still be present many years hence. After the clean up of the area, the places where the steel and rubble were stored would still contain easily detectable amounts of the pyrotechnic thermite, or super-thermite or whatever, today, now and for many years to come.
1550°C
The lowest I've found is 1200°C.
Whatever, that the chips ignited at a temperature far below the ignition temp. of any form of thermite is at least as indicative of the likelihood that the red/gray chips contain no unreacted thermite at all.
We have discovered that when a glass poor waste stream containing aluminum and steel is processed in the high temperature environment of the incinerator, a violent thermite reaction occurs. The thermite reaction generates enough heat and thermal shock to damage or destroy the incineration equipment. The present invention provides an inexpensive, effective method of preventing the thermite reaction.
During the high temperature incineration process in oxidizing atmosphere, aluminum and iron (steel) are converted to their oxides. In the absence of glass, the maximum rate of oxidation of iron (steel) is below 1200° C. and the maximum rate of oxidation of aluminum occurs at 1375° C. As a result, at 1200° C. molten aluminum metal is in contact with iron oxides (FeO, Fe 3 O 4 , Fe 2 O 3 ) and a violent thermite reaction between the aluminum metal and iron oxides is initiated.

Red/gray chips were subjected to heating using a differential
scanning calorimeter (DSC). The data shown in Fig.

samples all ignited in the range 415-435 °C.

You'll have to bear with me a little here - I'm not a chemist and I'm guessing you are.
You say thermite-like reactions in the WTC dust should not be considered anomalous because: "During the high temperature incineration process in oxidizing atmosphere, aluminum and iron (steel) are converted to their oxides. In the absence of glass, the maximum rate of oxidation of iron (steel) is below 1200° C. and the maximum rate of oxidation of aluminum occurs at 1375° C. As a result, at 1200° C. molten aluminum metal is in contact with iron oxides (FeO, Fe 3 O 4 , Fe 2 O 3 ) and a violent thermite reaction between the aluminum metal and iron oxides is initiated."
But this reaction is taking place in a high temperature incinerator in an oxidizing atmosphere. NIST reported "maximum upper layer air temperatures of about 1,000° C." at the WTC.
Are you claiming that a violent thermite reaction between the aluminum and steel would be initiated at 1,000° C or less?
Can you point to records of this process recorded at any other high-rise fire (many of which have burned longer and hotter)?
Surely if this were the case, any building constructed of steel and aluminium would be an incendiary device waiting to go off in the event of a fire.
But it was precisely this which lead them to conclude it was not thermite, but nano or super-thermite, which ignites at lower temperatures.

As measured using DSC, the material ignites and reacts vigorously at a temperature of approximately 430ºC, with a rather narrow exotherm, matching fairly closely an independent observation on a known super-thermite sample. The low temperature of ignition and the presence of iron-oxide grains less than 120 nm show that the material is not conventional thermite (which ignites at temperatures above 900ºC) but very likely a form of super-thermite.
