Researchers create 'rewritable magnetic charge ice'

A team of scientists working at the U.S. Department of Energy's (DOE) Argonne National Laboratory and led by Northern Illinois University physicist and Argonne materials scientist Zhili Xiao has created a new material, called ...

'Nanochains' could increase battery capacity, cut charging time

How long the battery of your phone or computer lasts depends on how many lithium ions can be stored in the battery's negative electrode material. If the battery runs out of these ions, it can't generate an electrical current ...

Researchers move closer to controlling two-dimensional graphene

The device you are currently reading this article on was born from the silicon revolution. To build modern electrical circuits, researchers control silicon's current-conducting capabilities via doping, which is a process ...

Smart skin is powered by the objects it touches

(Phys.org)—Researchers have fabricated a smart skin that is self-powered by its frictional contact with the objects that it touches. When a honeybee crawls across the smart skin, the skin not only senses the insect, it ...

Excitons pave the way to higher-performance electronics

After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices.
