Photo‐Switching Thermal and Lithium‐Ion Conductivity in Azobenzene Polymers

open access: yesAdvanced Functional Materials, EarlyView.
Light‐responsive azobenzene polymers control thermal and ionic transport simultaneously through structural transitions. UV illumination disrupts π–π stacking, converting crystalline trans states to amorphous cis configurations. Thermal conductivity drops from 0.45 to 0.15 W·m−1·K−1 while Li+ diffusivity increases 100 fold. This dual transport switching

Therapeutic Implants: Mechanobiologic Enhancement of Osteogenic, Angiogenic, and Myogenic Responses in Human Mesenchymal Stem Cells on 3D‐Printed Titanium Truss

open access: yesAdvanced Healthcare Materials, EarlyView.
This study investigates a synergistic effect between 3D‐printed surface features and mechanical micro‐strain in enhancing the osteogenic, angiogenic, and myogenic responses of human mesenchymal stem cells (hMSCs). Load‐induced mechanotransduction, facilitated by the implant's architectural design, significantly amplifies hMSC differentiation.

Beyond Bioactive Glass Composition: Using Morphology to Improve in Vitro and in Vivo Performance

open access: yesAdvanced Healthcare Materials, EarlyView.
Bioactive glasses can easily be shaped into granules, spheres, discs, fibers, or three‐dimensional scaffolds. The resulting morphology not only affects handling properties; it has a direct influence on various glass properties, including results of acellular immersion experiments or in vitro studies with cells or bacteria, but also on in vivo ...

A Robust Heparin‐Mimicking Polyglycerol‐Based Coating for Blood‐Contacting Devices with Long‐Term Hemocompatibility and Preliminary Anti‐Inflammatory Properties

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust heparin‐mimicking coating based on sulfated polyglycerol is constructed via layer‐by‐layer assembly on bloodcontacting surfaces. The coating exhibits long‐term anticoagulant and anti‐inflammatory properties by resisting protein adsorption, preventing platelet activation, and suppressing immune responses, offering a promising strategy for ...
