Nanoscale Diamane Spiral Spring for High Mechanical Energy Storage
Small, Volume 18, Issue 38, September 22, 2022., 2022 A 2D diamane‐based planar spiral is proposed as an alternative low‐carbon footage energy supplier for micro‐/nanoscale devices/systems based on its mechanical deformation. Supported by the theoretical analysis, atomistic investigations reveal that its gravimetric energy density can reach 2.03 MJ kg−1 or 564 Wh kg−1, about 14 500 times that of steel ...

Achieving superlubricity in DLC films by controlling bulk, surface, and tribochemistry [PDF]
, 2014 Superlubricity refers to a sliding regime in which contacting surfaces move over one another without generating much adhesion or friction [1]. From a practical application point of view, this will be the most ideal tribological situation for many moving ...
