By napping carbon and oxygen out of thin air, scientists have discovered a cheaper way to make preci

Vanderbilt University engineers have discovered how to break carbon dioxide in air into carbon and oxygen, and then stitch the carbon together to make carbon nanotubes -- a valuable engineering material. What one researcher called "black gold," the tiniest carbon nanotubes are stronger than steel ...This is an NSF Multimedia Gallery item.
