A hydrogen-informed Rice-Beltz model for crack-tip dislocation emission under mixed-mode loading
Kai Zhao
The fundamental competition between crack-tip cleavage and dislocation emission dictates the ductile-to-brittle transition in crystalline solids. In hydrogen-charged environments,…
Revealing trap depth distributions in persistent phosphors with a thermal barrier for charging
Ang Feng, Jonas J. Joos, Jiaren Du +1
The performance of persistent phosphors under given charging and working conditions is determined by the properties of the traps that are responsible for these unique properties. T…
Thermal Transport in MoS from Molecular Dynamics using Different Empirical Potentials
Ke Xu, Alexander J. Gabourie, Arsalan Hashemi +7
Thermal properties of molybdenum disulfide (MoS) have recently attracted attention related to fundamentals of heat propagation in strongly anisotropic materials, and in the con…
Interfacial thermal conductance in graphene/black phosphorus heterogeneous structures
Yang Chen, Yingyan Zhang, Kun Cai +4
Graphene, as a passivation layer, can be used to protect the black phosphorus from the chemical reaction with surrounding oxygen and water. However, black phosphorus and graphene h…
Superhigh moduli and tension-induced phase transition of monolayer gamma-boron at finite temperatures
Junhua Zhao, Zhaoyao Yang, Ning Wei +1
Two dimensional (2D) gamma-boron (γ-B28) thin films have been firstly reported by the experiments of the chemical vapor deposition in the latest study [Tai et al., Angew. Chem. Int…
A comparative study of two molecular mechanics models based on harmonic potentials
Junhua Zhao, Lifeng Wang, Jin-Wu Jiang +3
We show that the two molecular mechanics models, the stick-spiral and the beam models, predict considerably different mechanical properties of materials based on energy equivalence…
