本文报道了用原子力显微镜的尖端进行的纳米级弯曲实验，测量了几层(5~25层)自由悬浮的MoS_2纳米厚片的弹性变形。这些纳米薄片的杨氏模数非常高(E=0.33TPA)，可与氧化石墨烯的杨氏模数相媲美，并且变形可逆至数十纳米。
The elastic deformation of few layers ( 5 to 25) of thick, freely suspended MoS2 nanosheets by means of a nanoscopic version of a bending test experiment, carried out with the tip of an atomic force microscope is reported. Young's modulus of these nanosheets is extremely high ( E = 0.33 TPa), comparable to that of graphene oxide, and the deformations are reversible up to tens of nanometers.
