Candy cane supercapacitor could enable fast charging of mobile phones

Supercapacitors promise recharging of phones and other devices in seconds and minutes as opposed to hours for batteries. But current technologies are not usually flexible, have insufficient capacities, and for many their performance quickly degrades with charging cycles. Researchers now have found a way to improve all three problems in one stroke.

Atomically thin layers bring spintronics closer to applications

Researchers have created a graphene-based device, in which electron spins can be injected and detected with unprecedented efficiency. The result is a hundredfold increase of the spin signal, big enough to be used in real life applications, such as new spin transistors and spin-based logic.
