The graphic illustrates the design of a hybrid bilayer composed of a liquid crystal hydrogel (LCH) and a liquid crystal network (LCN). The figure highlights the magnetic alignment of the chromonic hydrogel and the thermal‐responsive actuation of the LCN along with the LCH when both layers are aligned or misaligned, enabling programmable, light‐driven ...

Harnessing Chain Mobility via Protonation for Tough and Isotropic Hydrogel
A protonation‐guided strategy enables ultra‐tough, isotropic PVA hydrogels by temporarily unlocking chain mobility via acidification and fixing homogeneous networks through salting‐out. The resulting materials simultaneously achieve high strength, extreme stretchability, and record‐level toughness, offering a generalizable route toward robust hydrogels

Metamaterial Antennas Enhance MRI of the Eye and Occipital Brain
A radiofrequency antenna platform comprising planar and bend configurations is developed, incorporating structurally integrated epsilon‐negative metamaterial unit cells to enhance MRI. These antennas enable high‐resolution in vivo human MRI of the eye, orbit, and occipital brain. Comprehensive validation, including simulations, phantom experiments, SAR,

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.
