Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction ...

Rolling two-dimensional materials into one-dimensional nanoscrolls unlocks tunable emergent properties; however, existing methods rely on external forces. Now, intrinsically driven scrolling in polar ...

Mechanical engineers at Duke University have demonstrated a proof-of-concept method for programming mechanical properties into solid Lego-like building blocks. By controlling the solidity of hundreds ...
