thiese things are not difficult to find with a little googling:
"We have invented a new method of making nanostructured energetic materials, specifically explosives, propellants, and pyrotechnics, using sol-gel chemistry"

- April 10,2000
this paper appeared on the internet in october 2000 just weeks after 911, but clearly the research dates back to at least 1995: "Nanoscale chemistry yields better explosives"
