Materials with negative Poisson's ratio attract considerable attention due to their underlying
intriguing physical properties and numerous promising applications, particularly in stringent …

Topological electronic materials such as bismuth selenide, tantalum arsenide and sodium
bismuthide show unconventional linear response in the bulk, as well as anomalous gapless …

Shape memory materials can maintain temporary shapes without external constraints and
revert to their permanent shape upon exposure to an external stimulus, such as heat, light …

Negative thermal expansion (NTE) is the phenomenon in which materials shrink rather than
expand on heating. Although NTE had been previously observed in a few simple materials …

Negative thermal expansion (NTE) alloys possess great practical merit as thermal offsets for
positive thermal expansion due to its metallic properties. However, achieving a large NTE …

Chemical pressure, a strange but familiar concept, is a lattice internal force caused by lattice
