New technique produces longer-lasting lithium batteries

The grand challenge to improve energy storage and increase battery life, while ensuring safe operation, is becoming evermore critical as we become increasingly reliant on this energy source for everything from portable devices ...

Expression of stop bands in forward volume spin waves

A research group led by assistant Professor Taichi Goto at Toyohashi University of Technology has, for the first time, demonstrated stop bands that prevent propagation of specific frequency components of forward volume spin ...

A stabilizing influence enables lithium-sulfur battery evolution

In late July of 2008 a British solar plane set an unofficial flight-endurance record by remaining aloft for more than three days straight. Lithium-sulfur batteries emerged as one of the great technological advances that enabled ...
