Packing the ions: Discovery boosts supercapacitor energy storage

Flat is in the eye of the beholder. When you're talking about nanomaterials, however, that eye is pretty much useless unless it's looking through an electron microscope or at a computer visualization. Yet the pits and ridges ...

New property of light discovered

A team of researchers affiliated with several institutions in Spain and the U.S. has announced that they have discovered a new property of light—self-torque. In their paper published in the journal Science, the group describes ...

Jumping drops get boost from gravity

A decade ago a new idea was brought into the general scientific community—shedding water from condensers was more efficient by using surface tension to make microscopic water droplets "jump" off the surface. The idea took ...

Collecting clean water from air, inspired by desert life

Humans can get by in the most basic of shelters, can scratch together a meal from the most humble of ingredients. But we can't survive without clean water. And in places where water is scarce—the world's deserts, for example—getting ...

Absorbing electromagnetic energy while avoiding the heat

Electrical engineers at Duke University have created the world's first electromagnetic metamaterial made without any metal. The device's ability to absorb electromagnetic energy without heating up has direct applications ...
