In Situ Nanomechanics
In situ nanomechanics is an emerging field that investigates the mechanical properties and deformation mechanisms of the nanoscale and nanostructured materials. The in situ nanomechanics study is usually conductedby integrating the real-time mechanical testing inside an electron microscope and the mechanics modeling with atomic resolution. It provides a powerful approach to visualize the intrinsic nanomechanical behavior of materials - seeing is believing. In this talk, several of our recent in situ nanomechanics studies will be presented, including the electrodedegradation in nanoscale lithium-ion batteries (Nature Nanotechnology, 7, 749, 2012);deformation-induced stacking fault tetrahedra in FCC nanocrystals (Nature Communications, 4, 2340, 2013); fracture toughness of graphene (Nature Communications, 5, 3782, 2014); and twinning-dominated deformation in BCC nanowires (Nature Materials, 2015). The in situ nanomechanics studies provide new insights thatcannot be offered by traditional mechanics studies. Ultimately, the in situ nanomechanics research aims to enable the design of nanostructured materials to realize their latent mechanical strength to the full. Our research involves collaborations with Drs.Scott Mao, Jianyu Huang and Jun Lou.
