Two weeks ago a german fellow found this patent by accident in search for an online discussion with so called debunkers, originally by searching the temperature of thermite burning.
US patent 5505799: called, Nanoengineered Explosives, Filed 1993, granted 1996,

I forwarded this patent to Prof. Harrit who did immediately respond and called it a good catch, and begged me I should write a blog entry about it. Also, Prof. Jones did respond immediately, too, with the multilayers working on his mind. Because this patent describes a three-layered “near” explosive material.

This patent looks like the manual for what was found in the WTC dust. Maybe the biggest hint is the last figure (31) published in the work “Actice Thermitic Material Discovered In Dust Of The World Trade Center Catastrophe” by Niels Harrit et al,

showing a residue with two red-grey-layers and other layers as well.

There are several sentences you have to read from the patent:

“A complex modulated structure of reactive elements that have the capability of considerably more heat than organic explosives while generating a working fluid or gas. The explosive and method of fabricating same involves a plurality of very thin, stacked, multilayer structures, each composed of reactive components, such as aluminum, separated from a less reactive element, such as copper oxide, by a separator material, such as carbon. The separator material not only separates the reactive materials, but it reacts therewith when detonated to generate higher temperatures. The various layers of material, thickness of 10 to 10,000 angstroms, can be deposited by magnetron sputter deposition. The explosive detonates and combusts a high velocity generating a gas, such as CO, and high temperatures”

“The reaction of metals (i.e. Al, Ti, Be . . . ) with inorganic oxides (i.e. CuO, Fe.sub.2 O.sub.3, MnO.sub.2 . . . ) is well known. For example, the reaction of Al and Fe.sub.2 O.sub.3 to produce Al.sub.2 O.sub.3 and Fe is referred to as the Thermite reaction, and it has been used for many years in metallurgical processes, such as welding.
Also, the enhanced reactivity of thin multilayer structures compared to powder mixtures has been observed by other researchers. The reactivity of thin multilayer structures is attributed to the energy stored in the layer interfaces and the very high ratio of interface area to volume.”

“Unlike organic explosive molecules, this explosive has properties that can be engineered because the structure is a fabricated multilayer not determined by molecular structure and bonding. It provides an alternative to any application for organic propellants or explosives. The stability of inorganic materials from which the new type explosive consists make it attractive for use in severe environments such a space applications. Also, the multilayer structure can be engineered to provide desired ignition temperatures and detonation characteristics. For example, the multilayer explosive can be engineered to be ignited by a mechanical scratch at room temperature, or to be as insensitive to ignition as a mixture of powder components. In addition, the ability to control the thickness (from 10 to 10,000 angstroms) of the various layers in the multilayer structure provide control over ignition sensitivity. Thicker layers in the multilayer structure produce a more stable material. In addition to beryllium, aluminum, and titanium, other inorganic elements or reactive metals such as lithium (Li), calcium (Ca), zirconium (Zr), and yttrium (Y), may be used. Also, the inorganic oxides of other metals, such as gallium (Ga), zinc (Zn), nickle (Ni), cobalt (Co), molybdenium (Mo), tin (Sn), and germanium (Ge) may be used. While carbon is the preferred organic component layer between the reactive layer and the oxide layer, other organic components (i.e. polymer films) which will react with both but also prevents any passivating reaction between the reactive material and the inorganic oxide material, may be used.”

I would call it only a manual, with strong evidence such material could in fact be developed long before 9/11, because, sure, there are at least the following differences:
-In the patent CuO (cupper-oxide) was used for the metal-oxide. In the red-grey chips described by Harrit et al they found FeO. However, FeO (iron oxide) is mentioned in the patent as the metal-oxide for well known thermite reaction (see above). What are the differences: CuO is faster in the reaction, but more expensive, too, as cupper is much more expensive than iron. There is no doubt that FeO can be used, too, with a little slower reaction front.
-there are three distinguishable layers, each useful for a special purpose, described in the patent: The CuO for the metal-oxide, the carbon layer for secure handling and creating carbide in the reaction and the Al-layer delivering the aluminum for the reaction. In the red-layer of the red-grey chip it looks like more than one of the features of the patents different layers were used, aka Al, FeO and C together. As there is the possibility, that more layers were used and only fragments of the layers were found, or that for other purposes the layers were even intermixed, it is no reason to undermine the meaning of this patent.
-magnetron sputtering is not a likely method for creating the amounts of nano-engineered explosives eventually used for the WTC destruction
-the term "explosive" shoud be used with caution, as there are clear definitions of it- we have a new stuff here, on the border between beeing explosive and incendiary

So, besides this, we can put a few things to rest: A stuff combining best of two worlds, as described later in science, a reaction speed likewise of explosives with the potential energy of incendiaries, nanomaterial layers capable of producing gas, carbides, very high temperatures in the reaction, like explosives, features adjustable just what you want from it, because of the adjustable layer features, known as early as 1993…means: Such stuff is possible. Don’t matter how often the “debunkers” will say thermite is not an explosive and the layers were much too thin for any harming of WTC steel. This looks like an important further step for reaching out to the criminals who did blow up the towers.

This patent can be found only randomly, if ever, in regards to 9/11 truth, e.g. you will find some comments on the web by harrasing "debunker" "Merlin5by5" on youtube or a short article by 911truth.ch. However, this information can be considered new to a wider audience, including the authors of the "Active Thermictic Material..." Even if it is not exactly the stuff that was used in the WTC demolition, hopefully it is a useful contribution for further studies.
