Stimuli‐Responsive Afterglow from Luminescent Liquid Crystal Elastomers

open access: yesAdvanced Materials, EarlyView.
An active glow luminescent system for encoding, signaling, and tracking in dark environments has been developed by integrating inorganic ultralong afterglow phosphors with adaptive liquid crystal elastomer actuators. Abstract Stimuli‐responsive luminescent polymeric materials which combine afterglow emission with mechanical flexibility and adaptability

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

open access: yesAdvanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced Materials, EarlyView.
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.
