Letters, a new material called porous colossal carbon tubes (CCTs) shows all the characteristics that could make it suitable for clothing and a possible replacement of cotton. Compared to traditional carbon nanotubes (CNTs), these colossal carbon tubes have...

a way to create these coiled nanotubes on a large scale. "The problem we have faced in the past is producing enough of these coiled carbon nanotubes at a reasonable cost to make a difference," said Rao. "Because our current method produces coiled nanotubes...

material needed to be highly conductive; material for cathodes usually needs to be highly insulating. However, the scientists were able to "coax" the M13 virus--modifying two genes-- into binding with iron phosphate first, and then binding with carbon nanotubes....

Letters.In the article, the researchers report that the experimental memory devices use an iron nanoparticle--1/50,000 the width of a human hair--that is enclosed in a hollow carbon nanotube. When electricity is applied, the nanoparticle can "shuttle" back...
