Multi‐Functional ZnO–Te Heterojunction Devices Enabling Compact Frequency Quadrupler

Advanced Functional Materials, EarlyView.
Wafer‐scale ZnO–Te heterojunction devices featuring tunable double negative differential transconductance (D‐NDT) are demonstrated at ≤ 200°C. Leveraging this unique characteristic, a single‐stage frequency quadrupler is realized, achieving a 64%–75% reduction in device count.

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

Advanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

Kinetic Regimes of Hydrogen Absorption in Thin Films

Advanced Functional Materials, EarlyView.
Knowledge of the hydrogen incorporation mechanisms in thin layers in relation to the amount absorbed is essential to design coatings and devices compatible with hydrogen‐based technologies. A combination of simultaneous in situ methods gives detailed insight into the hydrogenation of a prototypical hydrogen absorber layer in a time‐dependent manner ...

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Magnetothermal‐Triggered Response and Self‐Healing of Recyclable and Reprocessable Nanocomposites for Actuation Systems

Advanced Functional Materials, EarlyView.
Developing recyclable materials for magnetic robotics that combine rapid response and self‐healing properties is challenging. Hence, this study focuses on the integration of magnetothermal nanoparticles into a dynamic sorbitol‐based vitrimer, a recyclable composite capable of remote actuation and self‐healing by magnetic heating.
