Abstract: Atomically thin 2D graphene sheets exhibit unparalleled in‐plane stiffness and large out‐of‐plane elasticity, thereby providing strong mechanical resonance for nanomechanical devices. The exceptional resonance behavior of ultrathin graphene, which promises the fabrication of superior acoustic… read more here.

Abstract: Abstract We demonstrate a broadband high-efficiency acoustic absorber with subwavelength thickness. The acoustic absorber is based on meta-molecules can achieve near-perfect absorption. By adjusting structural parameters of meta-molecules, the acoustic absorber can offer absorption tenability… read more here.
