Fluctuating Curvature and Actuation in 4D Printed Asymmetric Networks by Frontal Photopolymerization
Advanced Materials Interfaces, EarlyView.Asymmetric polymer networks, fabricated by frontal photopolymerization (FPP), are shown to exhibit curvature oscillations associated with monomer‐solvent exchanges during development and drying. We introduce a theoretical model for such dynamic curvature fluctuations and demonstrate the fabrication of bistable switches and self‐propelled materials that

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
Advanced Materials Technologies, EarlyView.A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.

Microwave‐Assisted Aqueous Synthesis of Gelatin‐Norbornene for Hydrogel Crosslinking and Bioprinting
Advanced Materials Technologies, EarlyView.A microwave‐assisted reaction is utilized to synthesize gelatin‐norbornene (GelNB), achieving a high degree of norbornene functionalization while reducing the macromer's upper critical solution temperature. The resulting GelNB macromer has high solubility at room temperature, facilitating light‐based 3‐dimensional (3D) printing of thiol‐norbornene ...

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems
Advanced Materials Technologies, EarlyView.Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.
