Building Better Body Armor With Nanofoams

Nanotechnology... the next big thing.

I'll get my coat

It sure does make for annoying headlines; but 'nanotechnology' is sort of a concept that is doomed by nature to be spread vacuously thin across all sorts of things, both incremental advances and more remarkable stuff.

There probably a material in existence whose bulk properties don't derive from its structure at a fine scale, so the entire history of fields like metallurgy is 'nanotechnology' in a weak sense. On the other hand, though, most of that history, even to the present for economically viable bulk production, is largely messing around with heating and cooling parameters, and throwing various trace impurities into the mix, and then hoping really hard that the right nanoscale structures self-assemble.

The real problem is deciding where to draw the line between 'yeah, it's "nanotech" in the vacuous sense that all materials engineering is' and 'actually "nanotech" in some sense that makes it worthy of the title'...
