Programmable Chiral Radiation via Spin‐Decoupled Metasurface with Integrated Compound Phases

open access: yesAdvanced Science, EarlyView.
A programmable spin‐decoupled metasurface integrating propagation and geometric phases enables high‐purity chiral radiation with reconfigurable emission direction. Spin‐selective radiators combined with a compound phase decoupling strategy suppress undesired components, while embedded PIN diodes allow real‐time directional control.

Aligned Nanostructures Resolve Zn2+ Transport Bottlenecks via Interfacial Kinetics–Diffusion Coupling in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Science, EarlyView.
It is revealed that limited solid‐state Zn2⁺ diffusion within the cathode leads to interfacial Zn2⁺ accumulation, forming a transport bottleneck that distorts Zn2⁺ flux directionality. Through advanced analytical techniques, including in situ electrochemical impedance spectroscopy (EIS), distribution of relaxation time (DRT) analysis, and COMSOL ...

Dynamic Modulation of OECT‐Based Inverters for In Situ Electrophysiological Monitoring

open access: yesAdvanced Science, EarlyView.
This work presents a dynamic gain modulation system for inverter‐based in situ electrophysiological monitoring, enabling long‐term stable signal amplification via real‐time driving voltage adjustment. Moreover, stretchable complementary circuits (inverters, NAND, and NOR gates) are achieved based on a flexible PET substrate and a hexagonal network ...

Sensitive Sub‐THz Photodetection in Twisted Graphene with Broad Spectral Response

open access: yesAdvanced Science, EarlyView.
A dual‐gated twisted monolayer–bilayer graphene (TMBG) phototransistor enables ultrabroadband detection spanning visible to sub‐THz regimes. Gate‐tunable moiré bands produce photothermoelectric responses at zero bias and bolometric responses under applied bias.
