Nano-material is harder than diamonds

A material that is harder than diamond has been created in the lab, by packing together tiny "nanorods" of carbon.

 

The new material, known as aggregated carbon nanorods (ACNR), was created by compressing and heating super-strong carbon molecules called buckyballs or carbon-60. These molecules consist of 60 atoms that interlock in hexagonal or pentagonal shapes and resemble tiny soccer balls.

 

The super-tough ACNR was created by compressing carbon-60 to 200 times normal atmospheric pressure, while simultaneously heating it to 2226°C.

 

The properties of the resulting material were then measured using a diamond anvil cell at the European Synchrotron Radiation Facility in France. This instrument squeezes a material between two normal diamonds, enabling researchers to study it at high pressure using synchrotron radiation – extremely intense X-rays which reveal the material’s structure.

 

The researchers found their ACNR to be 0.3% denser than ordinary diamond and more resistant to pressure than any other known material.

Industrial applications

 

"Our material actually scratches normal diamonds," says Natalia Dubrovinskaia, of the University of Bayreuth, in Germany, who led the research. "We were very excited, and glad."

 

While an ordinary diamond gets its hardness from the strong molecular bonds between each of its atoms, ACNR derives its strength from the fact that it is formed from interlocking nanorods, the researchers say.

 

Dubrovinskaia told New Scientist the material could have a wide range of potential industrial applications. As it is stable at very high temperatures, she says it could be better than normal diamond for deep drilling and polishing abrasive materials. She also believes it will be easy to mass produce the super-tough material. "It's a very reproducible result," she adds.

Ya, that's the main aspect that gets my attention. As sumone else mentioned from another site, imagine planes that can withstand crash landings, and oil liners that would never leak.

 

but im seeing a new race to stock up on this material and make everything evil from them. terrorists and happy superpowers alike.

That's pretty neat... I wonder what kind of applications a material like this would have.

 

I bet rappers will get it in their teeth.

ya, i was already hearing the new lyrics and seeing the new episodes of cribs where everyones showing off their ACNR plated stretch escalades.

 

50 cent's gonna have to dump that lame bulletproof vest now.

Too bad the people inside are still going to liquify. I guess it saves the airline company some money though.

hey, i put a disclaimer in my post there yogi.

Yeah, also too bad: 50 cent thinks his bulletproof vest is made of teflon. Too bad thats a synthetic material used for nonstick pans and not for vests. Maybe he should invest in a kevlar vest before he invests in some new technology. Please correct me if im wrong, i wont be all but hurt about it...
