A Unified Mechanism for Hydrogen Trapping at Metal Vacancies
Weiwei Xing, Xing-Qiu Chen, Gang Lu +2
Interaction between hydrogen (H) and metals is central to many materials problems of scientific and technological importance. Chief among them is the development of H storage and H…
Interstitial-Boron Solution Strengthened WB
Xiyue Cheng, Wei Zhang, Xing-Qiu Chen +8
By means of variable-composition evolutionary algorithm coupled with density functional theory and in combination with aberration-corrected high-resolution transmission electron mi…
Rock-salt SnS and SnSe: Native Topological Crystalline Insulators
Yan Sun, Zhicheng Zhong, Tomonori Shirakawa +5
Unlike time-reversal topological insulators, surface metallic states with Dirac cone dispersion in the recently discovered topological crystalline insulators (TCIs) are protected b…
How Channel Segregates Originates: The Flow of Accumulated Impurity Clusters in Solidifying Steels
Dianzhong Li, Xing-Qiu Chen, Paixian Fu +5
The phenomenon, channel segregates (CS) as a result of gravity-driven flow due to density contrast occurred in the solid-liquid mushy zones1during solidification, often causes the…
