Termìte attiva scoperta tra i resti dell’esplosione al World Trade Center dell’Unidici Settembre

Molto importante questa scoperta!!(una foto a colori sarebbe l'ideale per individuare il core rosso)

The first WTC red/gray chip so tested was approximately 1mm x 1mm. After a few seconds of heating, the high-speed ejection of a hot particle was observed under the hand of the person holding the torch (Fig. 22). The intense light and bright orange color of the particle attest to its high tempera- ture. In this case, the attempt to recover the diminutive end- product of the reaction was unsuccessful.

comunque urge parere di un chimico, perchè ad una prima lettura pare un lavoro di un certo "peso"...

vabè...l'importane è poterlo scaricare.

3. Thermal Analysis using Differential Scanning
Calorimetry
Red/gray chips were subjected to heating using a differ-
ential scanning calorimeter (DSC). The data shown in Fig.
(19) demonstrate that the red/gray chips from different WTC
samples all ignited in the range 415-435 ˚C. The energy re-
lease for each exotherm can be estimated by integrating with
respect to time under the narrow peak. Proceeding from the
smallest to largest peaks, the yields are estimated to be ap-
proximately 1.5, 3, 6 and 7.5 kJ/g respectively.

dai...capire si capisce. E' scritto abbastanza chiaro. Semmai la cosa importante per noi ignoranti in chimica sarebe capire in che modo interpretare questi dati...perché leggendo così ad minchiam, risultano abbastanza pesanti.

è corretto aspettare la reazione del comico & C. in modo da valutare l'attendibilità e la consistenza dello studio

...mi sfugge il senso ma rispetto l'esigenza.

“Super-thermite electric matches” have been developed at Los Alamos National Laboratory for which “applications include triggering explosives for ... demolition” [30]. It is indeed possible that such matches, which are designed to be ignited by a simple electric pulse, could contain material similar to the red material we have found in the WTC dust. With regard to the safety of super-thermite matches, the Los Alamos announcement notes: “Unfortunately, conventional electric matches use lead containing compounds that are ex- tremely sensitive to impact, friction, static, and heat stimuli, thereby making them dangerous to handle. In addition, these compounds produce toxic smoke. The Super-Thermite electric matches produce no toxic lead smoke and are safer to use because they resist friction, impact, heat, and static discharge through the composition, thereby minimizing accidental ignition. They can be designed to create various thermal-initiating outputs—simple sparks, hot slag, droplets, or flames—depending on the needs of different applications” [30].

Capire se tale studio è inattaccabile come procedure e quindi come risultati.

Certo mi chiedo per averne trovato tracce addirittura nella polvere quanta roba c'era in ballo(?)

Fifteen small chips having a total mass of 1.74 mg were extracted from a 1.6 g sample of dust from which readily identifiable glass and concrete fragments had been removed by hand. Thus the fraction of red/gray chips was approximately 0.1% by weight in the separated dust Another sampling showed 69 small red/gray chips in a 4.9 g sample of sepa- rated dust. Further samples are being analyzed to refine this estimate. The fall of the WTC Towers produced enormous clouds of dust whose total mass is difficult to ascertain; but clearly the total mass of red/gray chips in the WTC dust must be substantial given the fraction observed in these sam- plings.

Thus, the energetic nano-composite can be sprayed or
even “painted” onto surfaces, effectively forming an energetic
or even explosive paint. The red chips we found in the
WTC dust conform to their description of “thin films” of
“hybrid inorganic/organic energetic nanocomposite”. Indeed,
the descriptive terms “energetic coating” and “nice adherent
film” fit very well with our observations of the red-chips
which survived the WTC destruction.

...avete visto la comparazione degli "XEDS spectrum" tra la thermite usata da paragone e le sfere originate dalla reazione in laboratorio ?

Diversamente che certezza c'è della provenienza dei campioni?

C'è scritto tutto...basta leggere.

On the morning of 9/12/2001, Mr. Stephen White of New York City entered a room in his apartment on the 8th floor of 1 Hudson Street, about five blocks from the WTC. He found a layer of dust about an inch thick on a stack of folded laundry near a window which was open about 4 inches (10 cm). Evidently the open window had allowed a significant amount of dust from the WTC destruction the day before to enter the room and cover the laundry. He saved some of the dust and, on 2/02/2008, sent a sample directly to Dr. Jones for analysis.
