Epsilon‐Negative Derived Electromagnetic Wave Absorption of Magnetic Metacomposites by Bifunctional Phase Paradigm

open access: yesAdvanced Science, EarlyView.
An epsilon‐negative response of up to 100000 in the radio frequency band is achieved by creating a metacomposite system with graphene/iron (III) oxide as the main body. The magnetic metacomposites are just like the mythical creature Qiongqi in Chinese mythology, capable of swallowing electromagnetic wave pollution that falls from the sky.

A Sub‐1 Nm Cluster Chains‐enhanced Poly(ethylene oxide) Electrolyte for an All‐solid‐State Lithium Metal Battery with a Long Cycling Lifespan

open access: yesAdvanced Science, EarlyView.
Sub‐1 nm inorganic cluster chain with cation vacancies optimize PEO electrolytes by eliminating Li+ migration barriers and constructing 3D ion transport networks, while in situ c‐AFM reveals dynamic transport mechanisms, enabling high‐performance all‐solid‐state batteries. Abstract Flexible composite polymer electrolytes (CPEs) are promising candidates

Mussel‐Bioinspired Edible Ca2+‐Crosslinked Alginate Hydrogel Electrodes for Glucose Gastrointestinal Monitoring

open access: yesAdvanced Science, EarlyView.
A fully edible soft electrode is engineered from Ca2⁺‐crosslinked alginate integrated with polydopamine, silver nanoparticles, and food‐grade glucose oxidase. The hybrid hydrogel combines ionic and electronic conduction, enabling efficient glucose‐to‐H2O2 conversion and catalytic reduction in simulated intestinal fluid.

Physical Origin of Temperature Induced Activation Energy Switching in Electrically Conductive Cement

open access: yesAdvanced Science, EarlyView.
The temperature‐induced Arrhenius activation energy switching phenomenon of electrical conduction in electrically conductive cement originates from structural degradation within the biphasic ionic‐electronic conduction architecture and shows percolation‐governed characteristics: pore network opening dominates the low‐percolation regime with downward ...
