temperature, high stiffness, high electrical, thermal conductivity23, and positive Poisson s ratio24, have been well studied. In contrast, for the 2D counterpart of these diborides, little information is currently available, let alone the mechanical properties. The elastic behaviour in 2D MB 2 can be totally different from the bulk.

However, it turns out that resistivity of LaNiO2 shows insulating be-haviour below 150 K. Then, the authors[1] explored La 1−xSrxNiO2 (x ≃ 0.2) which
