Two Faces of the Same Oxide: How Crystal Phase Defines the Nature of Proton Storage in MoO3

Abstract Proton storage in transition-metal oxides is often linked to fast proton transport, but how crystal phase governs structural evolution, electronic response, and kinetics remains insufficiently understood. Here, α-MoO3 and h-MoO3 are compared as model polymorphs to reveal...

Injectable Hydrogel Loaded With Umbilical Cord Blood‐Derived Exosomes Promotes Periodontal Bone Regeneration via the TLR4/NF‐κB Signalling Pathway

ABSTRACT Periodontitis is an immune‐mediated inflammatory disease characterised by progressive alveolar bone loss, which can lead to tooth loss in severe cases. Existing therapeutic agents have limited efficacy in reversing the associated inflammatory bone defects. Exosomes (Exos...

Breaking upstream–downstream linkage obstacles for efficient, economical, and green production of high-molecular-weight poly(β-L-malic acid)

Abstract Background Poly(β-L-malic acid) (PMA) is a biodegradable, biocompatible, and chemically modifiable polymer with broad applications. However, the production of high-molecular-weight, high-purity PMA (hhPMA) has long been constrained by “upstream–downstream linkage obstacl...
