Halogen‐Bonded Liquid Crystal Elastomers as Initiator‐Free Photochemical Actuators

open access: yesAdvanced Materials, EarlyView.
The combination of dynamic disulfide bonds and halogen bonds in chain‐extended liquid crystal elastomers enables the fabrication of photochemical actuators without the need for a photoinitiator, advancing the design of multimodal soft actuators that can be reprogrammed and reprocessed through supramolecular functionalization.

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions

open access: yesAdvanced Materials, EarlyView.
Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.

Spatially Resolved Observation of Ferroelectric‐to‐Paraelectric Phase Transition in a Two‐Dimensional Halide Perovskite

open access: yesAdvanced Materials, EarlyView.
Temperature‐dependent nanoscale ferroelectric domain evolution and the ferroelectric‐to‐paraelectric phase transition in 2D halide perovskites is visualized using piezoresponse force microscopy. The phase transition initiates locally below the Curie temperature and progressively propagates as paraelectric regions expand.

Spatially Controlled 3‐D Multiplexed Aptamer Patterning in Hydrogels

open access: yesAdvanced Materials Interfaces, EarlyView.
A hydrogel platform based on norbornene‐functionalized polyvinyl alcohol enables high‐resolution, 3‐D multiplexed patterning of DNA aptamers via two‐photon polymerization. Two distinct aptamers are covalently immobilized with single micron‐scale precision across the x, y, and z dimensions.
