A single molecule working as the nano scale version of the steam engine

A single molecule working as the nano scale version of the steam engine: that is the molecular motor developed by a group of UT scientists led by prof. Julius Vancso of the MESA+ Institute for Nanotechnology. Natural motor molecules, capable of converting chemical energy into movement, have been the source of inspiration for this new synthetic version: a polymer molecule that stretches and shrinks caused by redox reactions.

Superheated nanotubes gain strength as they stretch, researchers find

A single-walled carbon nanotube heated to more than 3,600 degrees Fahrenheit became nearly 280 percent stronger than it was in its original form, and its diameter shrunk by 15 times. The discovery has implications in strengthening ceramic and other nanocomposites at high temperatures and is useful in tuning electronics.
