High-entropy assisted capacitive energy storage in relaxor ferroelectrics by chemical short-range order by Tongxin Wei, Jinzhu Zou, Xuefan Zhou, Miao Song, Yan Zhang, Cewen Nan, Yuanhua Lin, Dou Zhang

“…We design a chemical short-range order strategy to modulate polarization response under external electric field and achieve substantial enhancements of energy storage properties, i.e. an ultrahigh energy density of ~16.4 J/cm3 with markedly improved efficiency ~90% at an electric field of 85 kV/mm in Nb doped (Bi0.2Na0.2K0.2La0.2Sr0.2) TiO3 system. Atomic-scale scanning transmission electron microscopy observations show that Nb exhibits a chemical short-range order structure, with Nb enriched regions displaying ultrasmall polar nanoregions and more flexible polarization configurations, which is conducive to achieving high maximum polarization and low residual polarization. …”

Molecular Dynamics Study on Crystallization Patterns in Tunnel Drainage Pipes in Alkaline Geological Environments by Xiangge Chen, Jie Zhou, Xuefu Zhang, Wenbing Yu, Shiyang Liu, Hongyi Liu, Yuhan Xiao

“…The goal is to study the interfacial interaction between CaCO3 and PVC and to reveal the effect of the alkaline environment on the adsorption of CaCO3 by PVC at the atomic scale. Analysis of the adsorption properties predicted by the CaCO3-PVC MD model reveals that CaCO3 molecules attract each other and form many atomic clusters at approximately 0.11 nm from the PVC interface. …”

Improving oxidation resistance property of single-crystal Ni-based superalloy via utilizing high temperature aging-induced dislocations by Boxuan Du, Yi Ru, Jiao Wen, Xuetao Li, Yang Cao, Yunpeng Hu, Fan Yang, Yanling Pei, Shusuo Li, Shengkai Gong

“…Taking advantage of such dislocations, the sample aged exhibited an extremely low oxidation rate, and a protective α-Al2O3 layer formed rapidly at the surface instead of multilayer oxides without the aid of aging dislocations, determining the change in oxidation mechanism. The atomic-scale investigation revealed that the Al had a higher activity in aged specimens, and the dislocation from aging treatment enabled the pipe diffusion effect. …”
