Toward a quantum computer, one dot at a time

Researchers at the University of Pittsburgh have developed a way to create semiconductor islands smaller than 10 nanometers in scale, known as quantum dots. The islands, made from germanium and placed on the surface of silicon with two-nanometer precision, are capable of confining single electrons.

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.

Big impact of nanocracks

An MIT researcher's atom-by-atom simulation of cracks forming and spreading may help explain how materials fail in nanoscale devices, airplanes and even in the Earth itself during a quake.
