Sustainable Revival of Spent Lithium Iron Phosphate Cathodes in Li‐Ion Batteries: Recycling and Surface Engineering Approaches

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Schematic illustration of the lifecycle of LiFePO4 cathodes. Lithiation and delithiation reactions happen through its discharging and charging processes. Recycling pathways including hydrometallurgy, pyrometallurgy, and direct regeneration enable sustainable reuse of spent LFP materials. Surface modification approaches (carbon, polymer, and metal/metal

Identification and correlation of the Aso‐3 tephra in the Omaezaki area, central Japan: A valuable key stratum for the MIS 6/5 transition period

Journal of Quaternary Science, EarlyView.
ABSTRACT The Aso‐3 tephra is one of the most significant widespread marker layers from the Middle to Late Pleistocene, generated by a large caldera‐forming eruption at the Aso volcano in Kyushu, southwestern Japan. Despite its importance, a distal co‐ignimbrite ash correlative has yet to be clearly identified, primarily because although volcanic glass ...

Polymaterial Lattice Discrete Particle Model for the Optimization of Lightweight Aggregate Concrete: Intragranular Fracture and Compression Behavior

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Lightweight aggregate concrete (LWAC) offers clear advantages for sustainable construction, including reduced density and improved thermal insulation. However, its mechanical and fracture behavior is difficult to characterize due to the heterogeneity and brittle crushing of porous lightweight aggregates.
