Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing

Advanced Materials Interfaces, EarlyView.
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...

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.

Ultra‐White Elastomeric Coatings for Daytime Radiative Cooling

Advanced Materials Technologies, EarlyView.
Passive daytime radiative cooling meets elasticity in a new class of ultra‐white silicone coatings. Combining high solar reflectance with strong sky‐window emission, they hold surfaces below ambient temperature under full sunlight while remaining flexible and stretchable. This combination of cooling performance and mechanical flexibility enables energy‐
