Vanishing Act Creates a Stir in the Nanotech World


Sheets Made of Microscopic Carbon Fibers Seem to Disappear When Heated
Oct. 25, 2011

Dr. Ali Aliev, a research scientist at UT Dallas, and his colleagues recently demonstrated that transparent carbon nanotube sheets, which can have the density of air and the specific strength of steel, can be used to make objects invisible.

This invisibility for light oblique to the nanotube sheets is caused by the mirage effect, in which a thermally generated refractive index gradient bends light array from a hidden object. The paper was published in a recent issue of the journal Nanotechnology.

The findings created a flurry of press coverage, including stories in CNN, ABC and Wired magazine. the rest
