Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Grain Boundary Structure Ordering via Electroshock Treatment Enhances Strength‐Ductility Synergy
Advanced Science, EarlyView.Electroshock treatment triggers atomic rearrangement, transforming disordered grain boundaries into ordered states without inducing recrystallization. This grain boundary ordering effectively relieves strain concentration and strengthens boundaries, enabling a simultaneous improvement in both strength and ductility.
