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.

Synthetic Chromatophores for Color and Pattern Morphing Skins

open access: yesAdvanced Materials, EarlyView.
Cephalopods use chromatophore organs (muscle‐actuated pigment sacs) to alter their skin color and pattern. Synthetic chromatophores, which closely mimic the mechano‐optical process found in cephalopods using stimuli‐responsive microscale hydrogel actuators, are reported.

Enhanced Deformability Through Distributed Buckling in Stiff Quasicrystalline Architected Materials

open access: yesAdvanced Materials, EarlyView.
Quasi‐periodic metamaterials combine stiffness and large‐strain deformability, overcoming limitations of traditional stretching‐dominated periodic designs that are prone to global buckling instabilities and catastrophic layer collapses. By leveraging non‐uniform force chains, they achieve high isotropic stiffness, stable deformation, and remarkable ...

Investigating Dopant Effects in ZnO as an Electron Transport Layer for Enhanced Efficiency in Organic Photovoltaics

open access: yesAdvanced Materials Interfaces, EarlyView.
By doping the elements with different numbers of valence electrons (Al3+ and Sn4+ ions) into the ZnO matrix, device conversion efficiencies of 8.69% and 9.21%, respectively, are achieved. The ultrafast time‐resolved studies show that the elevated carrier concentration in Sn‐doped ZnO, in comparison with Al‐doped ZnO and un‐doped ZnO, plays a ...
