• Size-dependent Phase Transformation and Fracture of ZnO Nanowires 

      He, Jianying; Wu, Jianyang; Nagao, Shijo; qiao, lijie; Zhang, Zhiliang (Journal article; Peer reviewed, 2017)
      The structural and mechanical properties of ZnO nanowires (NWs) have been systematically investigated by using molecular dynamic simulations based on the empirical Buckingham potential. Under tensile loading in <0001> ...
    • Structural Instability and Mechanical Properties of MoS2 Toroidal Nanostructures 

      Wu, Jianyang; Nie, Gaosheng; Xu, Jun; He, Jianying; Xu, Qingchi; Zhang, Zhiliang (Journal article; Peer reviewed, 2015)
      Molybdenum disulfide (MoS2) nanostructures have received considerable research attention due to their outstanding physical and chemical properties. Recently, a form of MoS2 ring structure exhibiting unique transport ...
    • Supergiant elasticity and fracture of 3D spirally wound MoS2 

      Wu, Jianyang; He, Jianying; Ariza, Pilar; Ortiz, Michael; Zhang, Zhiliang (Peer reviewed; Journal article, 2020)
      Recently experimentally synthesized three-dimensional (3D) MoS2 spiral is a new kind of helical structure with technically robust properties. Among them, the mechanical properties of such appealing materials are indispensable ...
    • Topology and polarity of dislocation cores dictate the strength of monolayer MoS2 

      Wu, Jianyang; Zhang, Zhisen; He, Jianying; Ariza, Pilar; Ortiz, Michael; Zhang, Zhiliang (Journal article; Peer reviewed, 2019)
      In contrast to homoelemental graphene showing common dislocation dipole with pentagon-heptagon (5|7) core, heteroelemental MoS2 is observed to contain diverse dislocation cores that tune the chemical and physical properties. ...
