Numerical Investigation of Mixed Mode I-III Fracture Behavior in Sandstone Under Static and Dynamic Loading

Mixed mode I–III fracture commonly occurs in rock masses under complex three-dimensional stress states, yet the combined effects of loading conditions and fracture mode remain unclear. In this study, a heterogeneous sandstone disc model is developed in ABAQUS by coupling the Druc...

Direct Regeneration of Spent LiFePO 4 Using Methionine for Defect Repair and N/S‐Doped Interface Construction

ABSTRACT The coming wave of end‐of‐life electric vehicles presents a formidable challenge for the recycling of spent Li‐ion batteries, particularly those with LiFePO 4 cathodes. The degradation of the LiFePO 4 cathode is primarily attributed to Li loss‐induced lattice defects and...
