Artificial limbs help to restore normal function to amputees. Surface materials for prostheses need to look realistic, hold up to exposure, and mimic skin. ORNL scientists combined superhydrophobic polymer inventions with carbon nanotubes to create a self-cleaning skin-like surface material with the ability to transmit heat. This material provides an improved external covering for mechanical prost…

Sensingindividualcarbon Contour plot of FE current (in nA) from an isolated VACNC, measured during a raster scan of the 2- m- diam probe at a height of 10 m above the substrate surface and biased at 300 V. The probe was scanned in discrete steps of 2 m with a current measurement taken after each step. Sensing Individual Carbon Nanotube Emissions Probe for mapping field emission from individua…

Carbon Nanotubes at Interface of Electronics, Aeronautics Show Exceptional Ability to Diffuse Damaging Heat Managing the heat in microelectronics is an ever-increasing problem.
