Nanoenergetics: An Emerging Technology Area of National Importance … 43
Dr. Andrzej Miziolek, Weapons and Materials Research Directorate, Army Research Laboratory
From the first experiments with gunpowder and fireworks to the latest ammonium nitrate and powdered aluminum high explosives,
man has sought to unleash the force of chemical explosives in more powerful and controlled ways. Nanotechnology allows
researchers to bridge the gap between pure chemical evaluation and microstructural analysis, and better understand the phenomena
which make energetics work. Dr. Miziolek presents a guided tour of some of the most groundbreaking work going on today in
energetics and how nanoscience is improving our understanding of one of our oldest weapons of war.
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
h a ve potential to be used in energetic formulations for
advanced explosives and propellant applications.
Figure 4 shows an example of the typical UFG aluminum
that is produced by the Indian Head process. A transmission
electron microscope (TEM) image of the Al nanoparticles is
shown on the left while an EFTEM (energy filtered TEM) is
shown on the right, clearly indicating a thin passivation layer of
A l2O3. These images we re taken at Lawrence Live r m o re
National Laboratory (LLNL). In summary, much more
research and development needs to be done in the production
and characterization of these and new types of MIC formulations.
Issues of MIC ignition and safety characteristics (such as
impact, friction, and electrostatic initiation) are promising, but
need to be fully explored. Overall though, certain key MIC
characteristics are very attractive and quite promising for practical
applications. These include energy output that is 2x that
of typical high explosives, the ability to tune the reactive power
(10 KW/cc to 10 GW/cc), tunable reaction front velocities of
0.1-1500 meters/sec, and reaction zone temperature exceeding
3000K. Specific areas of possible applications include use in
environmentally clean primers and detonators, chem/bio agent
neutralization, improved rocket propellants, IR flares/decoys,
thermal batteries, and others.

Please stop spreading disinfo.
From a pic by SPreston. Look up the information if you don't believe. As far as I have uncovered, this is true.

Everything you link to displays your inability to comprehend even the basics of thermodynamics. Instead of Googling scientific jargon out of context that sounds like your notion of thermite as an explosive try learning the basics of the complex chemistry involved. It means opening books and reading hundreds of pages of dense text.
Maybe you'll be able to explain how a millimeters thin layer of allegedly thermitic material with the same composition of primer paint caused a building to collapse. Practicing professional chemists, demolitionists, structural engineers, can't.

OK. I'm done with you. Did you even take the time to read the ten pages that I linked to?
