MnO₂ catalyzed hydrothermal regeneration of spent LiFePO₄ cathode materials for sustainable lithium-ion battery recycling

This paper presents a recyclable MnO₂-catalyzed hydrothermal strategy that achieves high-value regeneration of spent LiFePO₄ cathodes by synchronously compensating lithium and reducing iron to restore crystal structure, resulting in electrochemical performance comparable to pristine materials while offering a sustainable and low-cost recycling solution.

Solanum torvum Leaf-Mediated Phytogenic Engineering of Zn- and Sr-Doped MgO Nanoparticles as an Efficient Photocatalyst

This study demonstrates that Zn- and Sr-doped MgO nanoparticles synthesized via a green *Solanum torvum* leaf-mediated route exhibit significantly enhanced visible-light photocatalytic activity for methylene blue degradation, with Zn-doped MgO showing superior performance due to bandgap narrowing and reduced electron-hole recombination.

Preparation and Pore Structure Characterization of Balsa Wood (Ochroma pyramidale)/GO Composites

This study demonstrates that pretreating balsa wood with Na₂SO₃/NaOH followed by vacuum impregnation with an optimal 3‰ graphene oxide (GO) concentration creates a composite with enhanced thermal stability and a hierarchical, well-connected multiscale pore structure, whereas deviating from this specific GO concentration compromises the desired pore architecture.
