Abstract:The fragility works as a fundamental concept characterizing glass‐forming liquids, whereas its atomic structural interpretation remains a challenge. Herein, viscosity behaviors in polyethylene (PE), S, Se, and Te are examined, which consist of distorted chain molecules with varied interchain strength, in comparison with that in SiO2, a typical strong material. Among the 1D materials, S and PE appear to be fairly strong. Such results suggest that the viscosity exhibits Arrhenius‐type behaviourif it is governed … Show more
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.
