Deep Underground Science and Engineering, EarlyView.Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Low‐temperature carbonization and sulfur doping increase defect density and tailor surface area, enabling the formation of a thinner, more stable SEI, enhancing rate performance and the ICE. The S/C composite delivers an ICE of 83.1% and 480 mAh g−1 at 0.1 A g−1, retaining 232.6 mAh g−1 at 5 A g−1 for SIBs and achieves a considerable capacity of 439.2 ...
