The team broke the world hardness record by combining quantum mechanics, chemistry and mechanical engineering. They synthesized polyyne, a superhard molecular rod comprised of acetylene units - that resists 40 times more longitudinal compression than a diamond. Ironically, these glittery gems are comprised from the element carbon and have the weakest type of chemical bonds, while polyyne has the strongest bonds in carbon chemistry.

The downsides of such a material are very minimal IMO because of the bonds used(if you're thinking of molecular fallout).
As for the applications it could make lightweight frames for cars, nature-proof housing for 3rd world countries(maybe not this in particular but something along the lines of Ultra-lightweight modular housing units with embedded solar cells in the actual material to bridge the electricity and digital divide.

Embedded solar cells in construction materials? When?
And light weight, strong, safe cars? ...Is the material more like kevlar or steel?

Is it me or are we advancing faster and faster in technology?
Is there no limit?

Looks like we are getting closer and closer to the limits of material science.

Other composites that absorbe and crumble maybe some type of memory alloy that can repair itself when an specefic electrical charge is induced.

You don't think there are limits to materials science? How much stronger can we get it?
And really was that veiled insult necessary Frosty?

I dont see that happening for a very long time.
Metal is made to have a certian elastic limit, but its pretty minimal. If you crash your car, its unlikely you wil have a easy dent that could pop out, its far more likely there will be torn metal, scratched paint, and metal creases...So the bodyman wont go away for a long long time.

Who said anything about metal? What kind of metal do think is incapable of this, transition, alloys, organo, etc?

Sardion2000 aside from Polyyne being cost affective enough to be available to the general market do you think Polyyne is an ideal choice for armor?

an alloy is metals.
and I think all metals are incapable of doing that.
But I dont see any practicle use for that.
Take that same strip of metal and bend it 180 degrees and hit it will a hammer, I dont care how much water you put on it, it will not go back to normal.
Originally posted by sardion2000I personally believe that an effective armour using nanotech would stiffen upon impact rather then being hard armour it would look like padded armour.
As for cost effectiveness it's way to early to even speculate.

I notice that they don't mention the strength increase in the other directions. (if any) The compression resistance in the transverse plane might be totally different. That doesn't mean the material is useless, but it does mean that it has to be considered in any design using this material.
