Carbon Nanotube Forest Camouflages 3-D Objects (image) American Institute of Physics Caption Scanning electron microscope images show a tank etched out of silicon, with and without a carbon nanotube coating (top row). When the same structures are viewed under white light with an optical microscope (bottom row), the nanotube coating camouflages the tank structure against a black background. Credit L. J.
