Why Twisted Graphene Is One Of The Most Exciting Physics Stories Of The Year

Just a year ago, scientists presented results that seemed almost too good to be true: Carbon sheets only a single atom thick, called graphene, took on a pair of important physical properties when they were twisted at just the right “magic” angle relative to one another. If the atmosphere this…

A Graphene Speaker With No Moving Parts Uses Heat To Produce Sound

The traditional speaker design involves the use of a vibrating membrane that pushes air to create sound waves that travel to your ears. The technology has been in use for well over a century, but scientists at the University of Exeter might have found a way to improve how speakers…
