Physicochemical Reinforcement Unlocks Sterilization‐Stable Anisotropic Hydrogels for Cell‐Compatible Mock Arteries

Advanced Healthcare Materials, EarlyView.
ABSTRACT In vitro arterial models offer ethical and robust alternatives for vascular research but require cytocompatible materials that replicate physiological mechanics. Poly(vinyl alcohol) (PVA) hydrogels produced by directional freezing and salting‐out (PVA DFSO) are anisotropic yet lack stability for cell culture. Herein, methacrylated PVA (PVA‐MA)

Effects of temperature on the microstructural evolution and mechanical properties of copper − bearing medium manganese steel during tempering

Materials & Design
This work introduced the effects of higher tempering temperatures on the microstructural evolution of Cu − bearing medium Mn steel. After quenching steel at 860 °C for 1 h, it was tempered at 600, 640, and 670 °C for 2 h.

Seta‐Inspired Mechano‐Intelligent Janus Bandage with Coordinated Adhesion–Contraction for Minimizing Scarring

Advanced Materials, EarlyView.
We developed a bioinspired mechano‐intelligent Janus bandage (MIB) with a hydrophobic flat exterior and a hydrophilic interior featuring gecko‐mimicking wedged microstructures, fabricated via micromolding and anisotropic plasma treatment. The MIB dynamically synchronizes adhesion and contraction, enabling precise force modulation.
