There is no such thing as nano super-duper uber thermite, err thermate. It does not exist.
Don't tell Dr.Jones!
There is no such thing as nano super-duper uber thermite, err thermate. It does not exist.
This is what is so hilarious about the truthers and Jones' samples and the Harrit et al paper. When you look into the sol gel process and it's use in producing nano-sized particles for use in a thermite reaction (of what ever flavour) you find that when comparing the material in the papers with the Harrit paper that the materials are so far apart in their size, morphology and chemistry that only an idiot can't see the difference. What's even more amusing is that various papers on these nano materials get heats of reaction below the theoretical maximum for the classic thermite reaction (namely Fe2O3 + 2Al) at around 3.5 kJ mol-1 and Jones gets above the theoretical maximum for the same reaction and then declares it must therefore be super-thermite! Also note that a reduction in particle size corresponds with a reduction of ignition temperature yet Jones' chips ignite at an even lower temperature yet the particle size of the material in the chips is at least 10 and 40 times larger for the Fe2O3 and Aluminosilicate respectively!I've realized that the particle in Jones' paper is not very nano.

The best magnified pictures (Fig. 8-10) they have shows particles in size of sub-microns (hundereds of nanometers).
Pictures in other articles about "nano-explosives" show much smaller particles.

Some of them are only 30 nm in diameter.
To me, the particles Jones found seem too large.

So how does that work? Higher than theoretical maximum output with a lower ignition temperature, but with a far larger particle size than the best that can be produced by current processes under laboratory conditions. Mmmmn. Something isn't right is it. Perhaps the combustion was due to the Carbon matrix in the samples and not a thermite reaction as claimed. No wonder the poor editor resigned when crap like this ended up being published under her remit.

Tillotson et al. said:Integration of the exothermic peak in Fig. 3 resulted in a heat of reaction value of 1.5 kJ/g. This is significantly lower than the theoretical value of 3.9 kJ/g. One potential explanation involves the aluminum fuel itself. We know from HRTEM analysis that the UFG Al used in this sample has an oxide coating of ~5 nm. With 30 nm diameter Al this oxide coating represents a large amount of the mass of the sample. In fact, a simple calculation, based on the volume of the oxide coating, indicates that the UFG aluminum used is actually 70% Al2O3 weight.
Isn't it true that the Al + O2 reaction creates about twice as much heat, per mole of Al, as the thermite reaction? Since Harrit's DSC was done in air, shouldn't this force the actual (not just the theoretical) energy density observed to be higher than the measured energy density in vaccuum, or inert gas?This is what is so hilarious about the truthers and Jones' samples and the Harrit et al paper.

Exactly. In the paper by Tillotson et al., they specifically remark how their sol-gel thermite is substantially lower power:
... so, again, why was this miracle stuff used? Even ordinary thermite would be superior in every way: Higher energy density, higher resistance to preignition, lower chance of detection after the fact, more easily manufactured, cheaper, and it actually existed prior to 2001.Originally Posted by Tillotson et al., Part 4

If you still can't figure out why Dr. Jones's own data shows the stuff isn't thermite, then you really need to seek help from a professional. We've made it about as clear as we can.
The advantages of the nanothermite -- the real nanothermite made by Tillotson and his team -- are that it is more uniform and predictable, has a relatively fast reaction time, and has a substantially LOWER ignition temperature than normal thermite, yet high relative to some other compounds including explosives. However, it has an extremely low energy density, about 1/30th that of ordinary gasoline, and 1/3 that of TNT.
What you would want in the WTC case is something with inordinately high energy density, an extremely high thermal stability, and a very low reaction rate. Real nanothermite does not fit this bill at all.
What Dr. Jones has found is a substance that burns readily in air, ignited at ordinary fire temperatures, and has a wildly varying energy content albeit in no way competitive with normal combustibles like wood or paper, let alone jet fuel or gasoline. This is not a match to nanothermite, nor does it have properties advantageous or even faintly usable for any WTC demolition scenario.
It is, however, utterly consistent with organics containing sphere-like and plate-like structures of aluminum and iron, and their oxides, at decidedly larger-than-nano sizes. Like paint. Paint burns. Paint burns in air with a similar ignition temperature and a comparable energy density, and not being designed to burn would burn somewhat unpredictably depending on how it was dried and its substrate. Perfect bloody match to what Dr. Jones found.
I don't see what your problem is.
Perhaps because you're focussing on the least plausible one. While the most plausible scenario (I believe) for the use of nanothermite on 911, period, is as an incendiary for the jet fuel, the next most plausible 911 nanothermite scenario is what I'll call a slow CD one.
Do let us know when you, or anybody else, find a paint that they can ignite, after it's dried, that creates microspheres.
Also, I don't want to look it up now, but one of the French Henry's had remarked on the narrowness of the exotherm (i.e., power profile). While not supporting the notion of Harrit's red chip material as a slow CD agent, as a fireball incendiary, having that property may be ideal.
Why make up idiotic ideas about 911? Is your purpose to make moronic ideas up about 911?... (assuming it has foil-like properties; otherwise, you'd have to paint it on), wrapping that with fire insulation, ...
true..., there's no point to concocting scenarios of spiraling insanity regarding how it might have been used.
Good grief, man, an ignition system for the jet fuel??
You think the jet fuel isn't going to get ignited on impact? You think that, oh, just maybe 150 tons of shredding aircraft plowing through a structure isn't going to create any heat?
I'm not sure why you ask "open to the air". If you apply your nanothermite to a column, then cover up the column with fireproofing, it won't be "open to the air". If you apply it to columns in an impact area, you don't need to time anything. The impact will rupture Al platelets, the thermite reaction kicks off, and, as we all know, nanothermite flames propagate very quickly. (Hopefully, Harrit, et. al, will do an experiment where they bang on it with a hammer, and see if it ignites. In fact, I'll ask them about this. If they can't get one to ignite by hitting it with a hammer, then I would doubt this impact ignition method I'm suggesting.)You think somebody put igniters -- open to the air -- that were coordinated not just with the impact floor, but also with the correct time of impact, to within +/- 1/2 second?
That's the most plausible scenario you can imagine?![]()
If you mean microspheres of the size that Harrit obtained, from chips of the width and size that Harrit was using, then the reason I don't think that there were such microspheres to begin with is the fact that this is a debunking web site, and nobody has posted such pictures. If somebody actually has such evidence, but has been shy to produce it, perhaps reading this post will help them lose their shyness.What makes you think there weren't microspheres to begin with?
No, I haven't. Apparently, if anybody else who frequents this site had looked at iron oxide (primer) paint under the microscope, and found similar spheres, of similar size, they're holding out on us. If they now lose their shyness, recall the brand of paint, create paint chips of that specific brand, burn them to isolate the spheres, and post the photos, we can at least speculate as to whether or not doing a similar DSC on them, as had Harrit, will create a similar DSC plot.Ever put iron oxide (primer) paint under the microscope? Didn't think so. And there are other possibilities besides.
It'd be even more surprising if your organic paint primer, while burning at more or less the same temperature, managed to create a larger microsphere out of any smaller micropheres. Not if the temperature burning in open air is far less than the melting point of iron.The "narrowness," huh. As in, the organic paint binder all ignites at more or less the same temperature. Well, golly, what a surprise.
Not if it's a part of one's religious faith that something cannot be thermite - in which case, the fact don't matter.What you're doing is called the Texas Sharpshooter Fallacy, the most extreme example of it I've ever seen. There is absolutely no reason to believe this stuff is thermite, not of any stripe,
I find this to be a curious statement. If it's a highly engineered incendiary that has no business being in the WTC, that can't be good. If it's a paint chip or other coating, then nobody will claim that it's malicious, anyway.nor is there any reason to believe it's in any way malicious.
Do you realize that this is basically the opposite of what Dr. Greening had written, at one point?If we can't get past that, there's no point to concocting scenarios of spiraling insanity regarding how it might have been used.
(Hopefully, Harrit, et. al, will do an experiment where they bang on it with a hammer, and see if it ignites. In fact, I'll ask them about this. If they can't get one to ignite by hitting it with a hammer, then I would doubt this impact ignition method I'm suggesting.)
I have speculated that the most plausible 911 nanothermite scenarios are the following, from most plausible, to least plausible:
1) incendiary, to make jet fuel turn into a fireball in about 1/3 second
2) slow CD, wherein a thin layer is applied to heat the columns, causing them to fail under their pre-existing loads
3) explosive CD
If 1) is, indeed, plausible, then I would further expect that one possible way to ignite a nanothermite igniter, itself, is simple impact. That certainly solves any timing problems.But, in this case, I would also expect a chip to also ignite under action of a hammer blow.
Hence, my question: Are the red/gray chips stable to hammer blows, or will they ignite?
Sure I do, just like I 'think' Allied incendiary bombs, even if they hadn't added thermite to them, would have created heat when they came crashing through buildings after falling thousands of feet. And yet, thermite was added to them, anyway. Do yo think that was a wasteful mistake?
I'm not sure why you ask "open to the air". If you apply your nanothermite to a column, then cover up the column with fireproofing, it won't be "open to the air".

This being JREF, I doubt that anybody will actually attempt that. It's so much easier to bloviate.
In fairness, I'll note that I also doubt that a single 911 Truther will have done any such simple tests on primer paint, either - including the ones proclaiming how wonderful the Harrit paper is, without bothering to take it to their local university physical chemistry department, first, to see what they think about it.
t'd be even more surprising if your organic paint primer, while burning at more or less the same temperature, managed to create a larger microsphere out of any smaller micropheres. Not if the temperature burning in open air is far less than the melting point of iron.
BTW, at this point I'd like to mention something about the DSC tests which confuses me. Since the exotherm in the DSC occurs well before the melting point of iron (430 C vs. 1538 C), how come there are not additional exotherms at a higher temperature?

Do you realize that this is basically the opposite of what Dr. Greening had written, at one point?
The reason I have talked about scenarios of different plausibility, is primarily because debunkers have focused on the question of how it could be used, trying to infer insights from that about what it is - or rather, is not.
How about you? What if you look up one of your old physics professors, and ask them to rank the plausibility of the 3 scenarios of nanothermite in a WTC context that I mentioned? Will they even be able to answer you without snide remarks about "spiralling insanity"?
GivenIsn't it true that the Al + O2 reaction creates about twice as much heat, per mole of Al, as the thermite reaction? Since Harrit's DSC was done in air, shouldn't this force the actual (not just the theoretical) energy density observed to be higher than the measured energy density in vaccuum, or inert gas?
While the Harrit DSC tests may be ambiguous, I don't think they're inconsistent with thermite. Why on earth do you?
<snip>
If an oxygen molecule is going to react with Al inside a platelet, do you really think it needs to burrow in from the edge? Do not the most simple, geometrical considerations, plus science lessons about the relationship between surface area and volume that we learned in 7th grade, suggest to you that the average distance between oxygen outside a platelet, and Al inside, is going to be determined primarily by the thickness of a platelet, rather than it's area?

Just sent off an email to Harrit, et. al.:
Interesting that the HOW question keeps coming up, when the WHO and WHY questions are clearly more pressing: once we find out WHO made this material and WHO placed in the building, investigation/interrogation can then find out HOW the nanothermite was used. Pressing justice is even more important!
I do not care to be distracted by "HOW" speculations that cannot be answered by any physical testing.
The question about whether the red material can be ignited by impact, OTOH, can be tested and is worthwhile.
