@glitterbag,
Quote:I can't possibly be the only retired DOD person
Are you proud of spending your life with an organization that has far more committed more war crimes than the Nazis, has illegally invaded more nations than the Nazis,
Are you proud that usa military nanothermite was used to blow up WTCs 1,2 and 7?

Nanoscale Chemistry Yields Better Explosives
ONE thousand years ago, black powder was prepared by grinding saltpeter, charcoal, and sulfur together into a coarse powder using a mortar and pestle. Since then, the equipment for making energetic materials-explosives, propellants, and pyrotechnics-has evolved considerably, but the basic process for making these materials has remained the same. That, however, is changing, thanks to an explosive combination of sol-gel chemistry and modern-day energetic materials research.
At Livermore Laboratory, sol-gel chemistry-the same process used to make aerogels or "frozen smoke" (see S&TR, November/December 1995)—has been the key to creating energetic materials with improved, exceptional, or entirely new properties. This energetic materials breakthrough was engineered by Randy Simpson, director of the Energetic Materials Center; synthetic chemists Tom Tillotson, Alex Gash, and Joe Satcher; and physicist Lawrence Hrubesh.
These new materials have structures that can be controlled on the nanometer (billionth-of-a-meter) scale. Simpson explains, "In general, the smaller the size of the materials being combined, the better the properties of energetic materials. Since these `nanostructures' are formed with particles on the nanometer scale, the performance can be improved over materials with particles the size of grains of sand or of powdered sugar. In addition, these `nanocomposite' materials can be easier and much safer to make than those made with traditional methods."
