External Stimuli‐Activable Single‐Atom Nanozymes for Bioapplications
Small, EarlyView.Stimuli‐activable single‐atom nanozymes (SANs) are reviewed from materials design to biomedical applications. We explain electronic‐structure tuning principles and synthesis strategies that maximize the responsiveness of metal active sites and supports to light, ultrasound, and magnetic fields.

Harnessing energy metabolism for enhanced bone defect repair: Mechanisms and therapeutic strategies
VIEW, EarlyView.This review addresses the critical challenge of bone defect repair by focusing on the underexplored role of cellular energy metabolism. It synthesizes regulatory mechanisms in bone‐forming cells and sums up innovative strategies—leveraging cell derivatives, active factors, and biomimetic scaffolds—to modulate metabolism for enhanced regeneration.

Pressure Pulses Generated by Wire‐Guided Discharges in Water
High Voltage, EarlyView.ABSTRACT The hydrodynamic characteristics of underwater wire‐guided discharges and their relationships with the wire length and pulsed circuit parameters are not fully understood. In this paper wire‐guided discharges using wires of length 3, 5 and 7 cm and diameter of 0.05 mm have been investigated. The energy available to the discharges was 162.3 J at

Journal of Prosthodontics, EarlyView.Abstract Purpose Few studies have explored the bone response in dental implant sites prepared using a piezoelectric device, indicating moderate effectiveness in enhancing secondary stability and osteogenesis. This study seeks to expand our understanding of the changes in biological, clinical, and radiographic parameters, during the initial phases of ...
