@paco_Hast du die ganze LLNL-Studie gelesen? Mann, ich habe dafür fast 20 Minuten gebraucht. Noch jemand am Start, der behaupten möchte, so ein Zeug gäbe es nicht?

Energetic multilayer structures, also referred to as energetic nano- laminates, are described in U. S. Patents 5,538, 795 (Barbee, et al. ), herein incorporated by reference, and 5,547, 715 (Barbee, et al. ), herein incorporated by reference. Energetic multilayer structures are made of two or more alternating unreacted layers of known composition.
Layer thickness varies from 40 A to 4000 A and reaction front velocity varies from less than 1 m/sec to 17 m/sec.
(Der Layer ist nur der Zünder der eigentlichen Explosivschicht!)
For example, silicon is an effective element to be included in an energetic multiplayer.
The energy release rate is determined by the reaction front velocity, the energy staved per unit volume of reactant, the volume of reactant consumed per unit time.
Metallic multilayer structures are known to have good environmental stability as they are currently used as precision reflective coatings on orbiting satellites such as the Transition Region and Corona Explorer (TRACE) and are thus exposed to harsh environments and stresses. Igniters comprising energetic multilayer structures coated with energetic booster materials can be tailored to be stable to environmental aging, i. e. , where the igniters are exposed to extremes of both hot and cold temperatures (-30 °C to 150°C) and both low (0%) and high relative humidity (100%).
Energetic bi-metallic multilayer structure foils can be dip-, spin-, or spray-coated with thermite-based sol-gel materials.
The Fe203/Al nanocomposites ignite and burn at temperatures exceeding 3000 K. Other thermite reactions are known to reach temperatures of 4000K.
A device (s) comprising energetic sol-gel coated multilayers when initiated by mechanical stimuli will generate sufficiently high temperatures as to lead to decomposition/deflagration/detonation of the Pb (N3) 2 transfer charge.
All numbers expressing quantities of ingredients, constituents, reaction conditions, and so forth used in the specification and claims are to be understood as being modified in all instances by the term"about". Notwithstanding that the numerical ranges and parameters setting forth the broad scope of the subject matter presented herein are approximations, the numerical values set forth in the specific examples are reported as precisely as possible.

Sogar die Möglichkeit der Benutzung eines Magnetrons für eine "Thin Film" Erzeugung wird angesprochen, was die Reste vielleicht magnetisch werden lässt.
