Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...

3D Bioinspired Hair‐Based Solar Evaporator for Efficient Water Harvesting
A bio‐derived solar evaporator inspired by blackbody radiation is developed using human hair waste. The vertically aligned hair structure enables broadband light absorption, efficient thermal localization, and rapid water transport, achieving high evaporation rates and stable desalination performance.

Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

Magnetic‐Field Dependent VB− Spin Decoherence in Hexagonal Boron Nitrides: A First‐Principles Study
This study investigates the decoherence of the VB− defect in h‐BN under external magnetic fields using first‐principles quantum many‐body simulations. A transition boundary distinguishing distinct decoherence regimes is identified, with its dependence on isotopic composition.
