Chirality hierarchical transfer in homochiral polymer crystallization under high-pressure CO2

Autor: Lei Zhang, Guoqun Zhao, Zhiping Chen, Xianhang Yan

Publikováno v: Nature Communications, Vol 15, Iss 1, Pp 1-11 (2024)

Abstract Ordered phase transitions are commonly correlated to symmetry breaking, while disordered phase transitions are characterized by symmetry restoration. Nevertheless, this study demonstrates that these correlation relations are not always appli
