Sapphire Stars in Nanotube Support Role

On crystal surfaces, nanotubes self-guide themselves into dense structures with exciting potential applications as sensors or integrated circuits

USC researchers have found that sapphire surfaces spontaneously arrange carbon nanotubes into useful patterns - but only the right surfaces.
Nanotubes are one-atom thick sheets of carbon rolled into seamless cylinders. They can be used to work as chemical sensors and transistors, like devices made from carbon's close chemical cousin, silicon.
