1) What is nano-thermite?

2) How does nano-thermite differ from ordinary thermite?

3) How is nano-thermite made?

4) Can I see some pictures of nano-thermite?
 
I thought this was a helpful description. Guess where I got it from.

The 221st National Meeting of the American
Chemical Society held during April 2001 in San
Diego featured a symposium on Defense Applications
of Nanomaterials. One of the 4 sessions
was titled nanoenergetics…. This session provided
a good representation of the breadth of
work ongoing in this field, which is roughly 10
years old.… At this point in time, all of the
military services and some DOE and academic
laboratories have active R&D programs aimed
at exploiting the unique properties of nanomaterials
that have potential to be used in
energetic formulations for advanced explosives….
nanoenergetics hold promise as useful
ingredients for the thermobaric (TBX)
and TBX-like weapons, particularly due to
their high degree of tailorability with regards to
energy release and impulse management [20].

From Jones' comic book.

If you read the citation that "[20]" refers to, you will find that the nano-thermite was used for ignitors, not as that bulk that goes "boom" and blows stuff up.
 
Speaking of the American Chemical Society...

The overarching theme for the Spring 2009 national meeting in Salt Lake City was nanoscience and nanotechnology. As theme organizer, Professor Paul Weiss, Editor-in-Chief of ACS NANO, developed the theme “Nanoscience: Challenges for the Future” and organized the Keynote Address, Plenary Session, as well as many exceptional nano-specific symposia integrated with the technical program sponsored by the ACS Divisions.

Why didn't they ask Dr. Jones to present?
Why didn't Dr. Jones submit his paper to their journal, Nano, which is about nanotechnology?

You're right it doesn't go boom because "nanoenergetics hold promise as useful ingredients for the thermobaric (TBX) and TBX-like weapons, particularly due to their high degree of tailorability with regards to
energy release and impulse management."

does anyone argue thermobaric weapons were used on 9/11?

well, other than the planes becoming impromptu fuel-air bombs

not sure that is correct - unless the fuel was fully or mostly mixed with sufficient air prior to ignition it was not acting as an FAB with big overpressure followed rapidly with big underpressure (crushes your inn:)ards then pulls them out), just as spreading fuel fire

That's what I said, the nanothermite is an ingrediant; the detonator.

TBX (thermobaric ) weapons work on big structures via a few PSI overpressure. In WTC, it would blow out all the windows and kill everyone and leave the frame intact.

TBX bombs go BOOM just like all explosives.

Nobody heard a TBX explosion at WTC on 9/11.

You lose again.

A few people that read the footnotes in Jones' paper do but they are clueless about the meaning of the words they quote.
 
I've realized that the particle in Jones' paper is not very nano.

http://www.bentham-open.org/pages/content.php?TOCPJ/2009/00000002/00000001/7TOCPJ.SGM

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.
 
Hold up, though. If I'm not mistaken, Jones doesn't claim to have found ACTUAL thermite, he merely claims to have found evidence that a thermite reaction occurred. How does the "signature", if you will, of super-thermites differ from that of standard thermites?

The main differences seem to be with the reactants and reaction, not with the products. Aren't the products going to be still basically the same?



I admit I only got a C in chemistry (I was in it more for watching things explode than for actually learning), so I apologize if anything I just said is horribly stupid.

As the mass transport mechanisms that slow down the burning rates of traditional thermites are not so important at these scales, the reactions become kinetically controlled and much faster.
Interesting. Would a greater reaction speed make it easier to use as a demolition device?

Yes, It also makes it go BOOM.

Nobody heard BOOM on 9/11.
 
There is no such thing as nano super-duper uber thermite, err thermate. It does not exist.
