The strong force that originates from breaking covalent bonds can be easily quantified through various testing platforms, while weak interfacial sliding resistance (ISR), originating from hydrogen bonding or van der Waals (vdW) forces, is very challe

Grain boundaries (GBs) and the spontaneous oxidization around GB regions are inherent features of graphene. In this paper, the thermal conductivity (κ) of oxidized polycrystalline graphene (PG) is studied using molecular dynamics simulation. The κ

The presence of defects not only modifies the stiffness and strength of materials, but also changes their morphologies. The latter effect is extremely significant for low-dimensional materials such as graphene. We show in this work that graphene swel

Linear elastic fracture mechanics (LEFM) implies that crack-like flaws would intensify stress in brittle materials with stress intensity scaling up with the square root of the crack size. Therefore, the apparent strength of materials tends to be much

The fracture of polycrystalline graphene is explored by performing molecular dynamics simulations with realistic finite-grain-size models, emphasizing the role of grain boundary ends and junctions. The simulations reveal a ~50% or more strength reduc

Thermal transport in solids changes its nature from phonon propagation that suffers from perturbative scattering to thermally activated hops between localized vibrational modes as the level of disorder increases. Models have been proposed to understa
