Mechanical properties of graphene [PDF]
Applied Physics Reviews, 2021 This paper reviews the mechanical properties of graphene with particular attention to what is established and what is still uncertain. It clarifies the thickness and the elastic constants, and by also considering also phonon frequencies, it argues that “best values” come from graphite, when available.

Misfit strain-induced mechanical cracking aggravating surface degradation of LiCoO2
Materials Research Letters, 2023 Cycling-induced cathode interfacial degradations are usually attributed to chemical process, while the physical effect is overlooked to a large extent. Herein, we investigate the failure mechanism of LiCoO2 cathode and reveal that misfit strain plays a ...
