Magnetically Responsive Piezoelectric Nanocapacitors Enhance Neural Recovery Following Spinal Cord Injury via Targeted Spinal Magnetic Stimulation

Advanced Science, EarlyView.
This study presents a novel “in vivo–in vitro” therapeutic strategy for spinal cord injury by leveraging magnetically responsive piezoelectric nanomaterials. These nanomaterials enable targeted delivery of localized electrical stimulation at the injury site through noninvasive external magnetic actuation, thereby promoting axonal regeneration and ...

Alkaline Phosphatase‐Activated NIR‐II AIEgens Nanosystem for Surgical and Postoperative Closed‐Loop Therapy of Advanced Osteosarcoma

Advanced Science, EarlyView.
This study designed a tumor microenvironment‐responsive AIEgen nanoparticle for near‐infrared photoimmunotherapy, which inhibits primary tumors and metastasis by promoting pyroptosis and suppressing aerobic glycolysis. ABSTRACT In advanced osteosarcoma, tumor invasion often prevents complete resection, and immunotherapy is limited by the tumor's ...

Assessing the reliability of laboratory test procedures for predicting concrete field performance against alkali-aggregate reaction (AAR)

Cement
Alkali aggregate reaction (AAR) affected structures show reduced serviceability and premature distress in over 50 countries worldwide. Several laboratory test protocols have been proposed to evaluate the potential reactivity of aggregates by varying the ...

Arbitrary 3D Organic Mixed Ionic‐Electronic Conductor Architectures via Self‐Fusion of PEDOT:PSS Microfibers

Advanced Science, EarlyView.
A general fabricating strategy for arbitrary 3D organic mixed ionic‐electronic conductor architectures is reported using PEDOT:PSS microfiber building blocks. A water‐assisted self‐fusion process is successfully developed in which adhesion can be modulated as reversible (PSS‐rich) or irreversible (PEDOT‐rich) self‐fusion depending on the post‐treatment
