Carbon nanotube-coated material moves when exposed to light

Due to nanotubes’ natural qualities, they can convert even small amounts of light into heat, leading to no-battery-needed motion. Researchers think the system could be used to create smart curtains that automatically draw when there is light.

How carbon nanotubes could save you from spoiled food

German researchers have come up with a cheap way to spray gas sensors, based on a relatively new material, onto thin film. If health fears are cleared, this could result in smart food packaging — perhaps with sprayed-on radio antennas, too.
