The New Black?

I must be an old fart because I had to Google the term 'None more black'.  That's one of the terms being used to describe a new material developed by researchers at Rice University.  How black is it you ask?  It is so black it absorbs more than 99.9% of light.  Composed of a carpet-like layer of carbon nanotubes, the new material is more than three as dark than the current record holder.  The team, led by Pulickel M. Ajayan, developed the material using hollow tubes of carbon atoms 400 thinner than a strand of human hair.  The tubes have a rough surface that cuts down on reflectivity and the use of tubes helps trap light in the spaces between the strands.  The current research has been restricted to visible wavelengths of light but could also have applications for other forms of radiation including stealth technologies.
