Multifunctional Oxadiazole‐Based Polycatenars: A Pathway to Polar Columnar Phases

Advanced Materials Interfaces, EarlyView.
Aromatic core fluorination directs oxadiazole‐based polycatenars into ferroelectric and antiferroelectric columnar phases with supergelation and photo‐responsiveness. ABSTRACT Polar columnar liquid crystals (LCs) offer a promising pathway to nanostructured architectures for next‐generation ferroelectric devices.

Light‐Programmable Interfaces: From Molecular Photoswitching to Adaptive Membrane Separations

Advanced Materials Interfaces, EarlyView.
This review advances an interface‐centered framework for light‐responsive membranes, linking molecular photoswitches (azobenzene (AZO), spiropyran (SP), diarylethene (DAE), donor–acceptor Stenhouse adducts (DASA), photoacid) to integration strategies in polymeric, porous, self‐assembled, and mixed‐matrix systems.

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.
