2D copper nanozyme patches facilitate bone regeneration via interfacial modulation of osteoclast‐osteoblast dynamics

BMEMat, EarlyView.
This study develops a nano‐enzyme patch (ezPatch) targeting bone interfaces. Utilizing ligand‐to‐metal charge transfer (LMCT) catalysis and bone‐targeting ligands on copper nanosheets, ezPatch simultaneously scavenges reactive oxygen species (ROS) and generates oxygen in situ at bone‐losing sites.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

Deep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Identification of invisible damage in prestressed concrete bridges—A demonstrator case using coda wave interferometry

Structural Concrete, EarlyView.
Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.
