Scientists at Los Alamos National Laboratories are exploring the potential to release
energy from nanoparticles – nano explosives. Nanoenergetics is a new field in which
nanoaluminum particles are used as more effective explosives. Just as with the suntan
products, the nanoaluminum presents a higher surface area to volume of the material.
This means that when ignited a greater volume of the aluminum achieves chemical
reaction, releasing its energy, and generating a larger explosion per pound of material.
Nuclear weapons achieve their destructive power in this same way at the very lowest
atomic level. This means that nanoaluminum and the “superthermite” that is made from it
are presenting significantly more powerful weapons than those in use today. Details on
this power and ongoing projects are not publicly available. But, it is instructive that the
experiments are being carried out at the same laboratory that created the designs for most
of the nuclear weapons in the US arsenal (Gartner, 2005).
The term, Metastable Intermolecular Composites (MIC) refers to an important subset of nanoenergetics. It is also known as a superthermite, or simply nanothermite, which are more descriptive terms. Typical compositions use a nanoscale metal fuel plus a nanoscale metal oxidizer. The reactions produce a large
amount of energy liberated primarily as heat. The high surface to volume ratio and the increased surface
contact between the reactants leads to a very rapid oxidation when compared to conventional (micronscale) thermites. This paper presents a mathematical model for the combustion wave propagation of consolidated and confined MIC pellets. In addition, a review of the current understanding of MIC as related to ignition and combustion mechanisms is presented and organized into four basic categories. Results of published and unpublished investigations on combustion mechanisms, such as ignition and burn rates are compiled and discussed so as to provide a single source of information for the technical community.
In recent years researchers have found that energetic materials/ingredients that are produced on the nanoscale have the promise of increased performance in a variety of ways including sensitivity, stability, energy release, and mechanical pro p e rties. As such, they represent a completely new frontier for energetic material research and development with the potential for major payoffs in weapons systems. Very simply, nanoenergetics can store higher amounts of energy than conventional energetic materials and one can use them in unprecedented ways to tailor the release of this energy so as to maximize the lethality of the weapons. The field of nanoenergetics R&D is quite young, but is already undergoing rapid growth. The goal of this article is to give the reader a sense for the physical and chemical characteristics and properties that make these materials so promising.
THERMITE FUEL-AIR EXPLOSION: This is a very dangerous device. Ask yourself if you really truly want to make it before you do any work on it.
It is next to impossible to give any dimensions of containers or weights
of charges because of the availability of parts changes from one person to
the next. However here is a general description of this device affectionately known as a HELLHOUND.
EXOTIC THERMITES: Thermites can also be made from teflon-magnesium or metalflourides-magnesium or aluminum. If there is an excess of flouride compound in the mixture, flourine gas can be released. Flourine is extremely corrosive and reactive. The gas can cause organic material to burst intoflames by mere contact. For teflon-magnesium use 67% teflon and 33% magnesium.A strong first fire igniter should be used to ignite this mixture. Both theteflon and the magnesium should be in powdered form. Do not inhale anysmoke from the burning mixture.

Exactly, I would have to look around again but I had just read where a professor and students tried to prove NIST's claim about aluminum pouring out of the building. They found that NIST was wrong, aluminum is silver even at the temperature that steel melts at and the office debris will not mix with it. They found that wood shavings and other materials would separate out and float on the top, so it is impossible for molten aluminum mixed with office materials to uniformly glow orange like we saw.
Try again NIST...
