Triboelectric generator captures power from friction

Researchers have discovered yet another way to harvest small amounts of electricity from motion in the world around us - this time by capturing the electrical charge produced when two different kinds of plastic materials rub against one another. Based on flexible polymer materials, this 'triboelectric' generator could provide alternating current (AC) from activities such as walking.

Tiny bubbles snap carbon nanotubes like twigs

A computer model from Rice University shows that long nanotubes bend and snap like twigs when blasted with ultrasonic energy. The research finds that short and long nanotubes behave differently during sonication. The discovery answers a longstanding question about the origin of competing power laws that were found in experiments on cutting nanotubes by sonication.
