en wat meer haar

ik denk echter dat het échte verhaal hierachter nooit boven komt.
mja misschien na 1000 jaar, na opgravingen ed.

Grappig overigens dat er over nano thermiet niets te vinden is met google, behalve op 9/11 gerelateerde paginga's.

thermite is a pyrotechnic composition of a metal powder and a metal oxide, which produces an aluminothermic reaction known as a thermite reaction. It is not explosive, but can create short bursts of extremely high temperatures focused on a very small area for a short period of time.

Thermites can be a diverse class of compositions. The fuels are often aluminium, magnesium, calcium, titanium, zinc, silicon, and boron. The oxidizers can be boron(III) oxide, silicon(IV) oxide, chromium(III) oxide, manganese(IV) oxide, iron(III) oxide, iron(II,III) oxide, copper(II) oxide, and lead(II,II,IV) oxide. [1]

The most common thermite is aluminium-iron(III) oxide.

The aluminium reduces the oxide of another metal, most commonly iron oxide, because aluminium is highly combustible:

Fe2O3 + 2Al -> 2Fe + Al2O3 + Heat

The products are aluminium oxide, free elemental iron, and a large amount of heat. The reactants are commonly powdered and mixed with a binder to keep the material solid and prevent separation.

The reaction is used for thermite welding, often used to join rail tracks. Other metal oxides can be used, such as chromium oxide, to generate elementary metal. Copper thermite, using copper oxide, is used for creating electric joints in a process called cadwelding:

3CuO + 2Al -> 3Cu + Al2O3 + Heat

Some thermite-like mixtures are used as pyrotechnic initiators such as fireworks.

Thermites with nanosized particles are described through a variety of terms, such as metastable intermolecular composites, superthermite nanothermite, and nanocomposite energetic materials.

Oke dan, stel dat alle bronnen die de 9/11 aan de kaak stellen doorgedraaide en paranoïde zwakbegaafden zijn, waarom dan alles geloven dat o.a. deze verlichte geest hieronder beweerd slimpie?

Oh, en nu nog even aantonen dat nano technologie in 1969 al in gebruik was en dat de architect Minoru Yamasaki ook opdracht had gegeven nano technologie daadwerkelijk te gebruiken

7. Could the Red Chip Material be Ordinary Paint?
We measured the resistivity of the red material (with very
little gray adhering to one side) using a Fluke 8842A multimeter
in order to compare with ordinary paints, using the
formula:
Specific resistivity = RA / L
where R = resistance (ohms); A = cross-sectional area (m2); L
= thickness (m).
Given the small size of the red chip, about 0.5 mm x 0.5
mm, we used two probes and obtained a rough value of approximately
10 ohm-m. This is several orders of magnitude
less than paint coatings we found tabulated which are typically
over 10¹⁰ ohm-m [31].
Another test, described above, involved subjection of red
chips to methyl ethyl ketone solvent for tens of hours, with
agitation. The red material did swell but did not dissolve, and
a hard silicon-rich matrix remained after this procedure. On
the other hand, paint samples in the same exposure to MEK
solvent became limp and showed significant dissolution, as
expected since MEK is a paint solvent.
Further, we have shown that the red material contains
both elemental aluminum and iron oxide, the ingredients of
thermite, in interesting configuration and intimate mixing in
the surviving chips (see Results, section 1).

GEOMET® is a proprietary water-based coating dispersion containing metal oxides, metallic zinc and aluminum flakes.
Solvent Resistant- Inorganic nature causes it to be resistant to organic solvents
Heat Resistant- Maintains corrosion resistance even following a heat shock of 3 hours at 550º F (288º C)
Conductive- Concentration of metallic flake allows an electrical current to be passed to the substrate

Red Oxide Zinc Chromate Primer
We offer Shilpi Redoxide Primer which is known for its good adhesion to substrate. It has fine anti-corrosive properties towards the metal. This primer is easily brushed or sprayed as it forms a hard & tough adherent coating.

Aluminum. Aluminum paint is probably used for more jobs than any other paint. It is a desirable coating for battleships and large bridges, since the dried film weighs less than half as much as the film of any other common paint. It is used to cover and protect steel structures and buildings, because it is durable and light-colored. It reflects light and heat more than any other paint and has a desirable decorative finish. It is commonly used as a body and final application over a red iron-oxide, zinc-oxide, or linseed-oil priming coat.
