Abstract:A 2D-layered network Zn[N(CN)2]2, is reported in which the transverse vibrations of C atoms and the rotation of ZnN4 tetrahedra dominate its biaxial NTE behavior.
“…9,10 The motif of layer structures such as flat and undulation significantly influences on the anisotropic structural transformation. For example, undulating layers in uniaxial 11,12 and bi-axial [13][14][15][16] directions are highly flexible due to the anisotropic and isotropic structural transformations, respectively, involving layer-expansion/contraction (Fig. 1).…”
Flat layers are usually considered as structurally rigid motifs in two-dimensional (2D) materials. In this work, we demonstrate that a flat honeycomb-layer composed of distorted tri-coordinate copper ions bridged with...

Discovering new negative thermal expansion (NTE) materials is a great challenge in experiment. Meanwhile, machine learning (ML) method can be another approach to search for NTE materials using the existing...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
