Thermal‐induced fracture evolution and acoustic signature of Beishan granite: Insights into tensile strength of barrier system for high‐level radioactive waste disposal

open access: yesDeep Underground Science and Engineering, EarlyView.
The tensile strength of granite, a proposed host for nuclear waste, degrades severely above 400°C. We link this to specific microcracking patterns captured by acoustic emission, establishing a scientific basis for assessing repository safety under thermal load.

Bifunctional Role of Surface Cobalt Doping as a Lithium‐Residue Scavenger and Surface Stabilizer in Single‐Crystalline Ultrahigh‐Ni Cathodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Surface cobalt coating on single‐crystalline NCA acts as a lithium‐residue scavenger and structural stabilizer. The protective layer suppresses moisture‐ and CO2‐induced reactions, mitigates crack formation, and inhibits the formation of NiO‐like rock‐salt phases. This dual‐function surface engineering enhances interfacial stability and electrochemical
