Computational predictions of hydrogen-assisted fatigue crack growth
A new model is presented to predict hydrogen-assisted fatigue. The model combines a phase field description of fracture and fatigue, stress-assisted hydrogen diffusion, and a toughness degradation formulation with cyclic […]

Influence of concentration-dependent material properties on the fracture and debonding of electrode particles with core-shell structure
Have you noticed that your phone battery seems to hold less charge than when you first bought it? One key reason is the mechanical fracture of electrode particles inside the […]

Disorder-Induced Transition from Transient Quantum Delocalization to Charge Carrier Hopping Conduction in a Nonfullerene Acceptor Material
In organic semiconductors, charge carriers may form delocalized or localized quasiparticles depending on molecular properties and environmental effects. Here, it is shown how structural and electrostatic disorder induce localization. Physical […]
