Researchers at Harvard have created a groundbreaking metasurface that can replace bulky and complex optical components used ...

The extension is no longer proportional to the applied force. is not exceeded, a graph of stretching force against extension is a straight line through the origin, because Hooke’s Law is obeyed.

However, when the applied force decreases, we find ourselves in an area where graphene exhibits typically auxetic properties," notes Kachorovskii. Discover the latest in science, ...
