Gel‐Free Capture of Microvolt‐Level Neural Signatures Via a 3D Monolithic Carbon Fiber Dry Electrode

open access: yesAdvanced Science, EarlyView.
A compressible carbon fiber/PEDOT:PSS electrode enables gel‐free contact at hairy scalp sites. Its conductive porous framework supports low interfacial impedance and retains contact performance after repeated mechanical and sweat‐related challenges.

Gd‐Mediated Spin‐State Modulation of Co Sites Enhances Oxygen Electrocatalysis in Zn‐Air Battery

open access: yesAdvanced Science, EarlyView.
The Gd‐mediated spin‐state modulation strategy was proposed to enhance electrocatalytic performance of Co sites towards oxygen reduction reaction. The Gd incorporation modulates the local electronic structure of Co centers by inducing pronounced spin splitting and orbital‐selective spin polarization, which optimizes the adsorption of oxygen‐containing ...

Label‐Free Super‐Resolution Imaging Using Non‐Linear Exogenous Photon Avalanche Backlight

open access: yesAdvanced Science, EarlyView.
Transmission avalanche backlight (TAB) microscopy turns a photon‐avalanching Tm3+:LiYF4 crystal into a nonlinear luminescent backlight. Weak attenuation by a transparent sample is amplified into strong emission modulation: image contrast increases with sample attenuation and avalanche nonlinearity (N), while the effective point spread function narrows ...

Boron Crosslinking Enables Anion‐Lean Solvation and Stable Interfaces for Dendrite‐Free Lithium Metal Batteries

open access: yesAdvanced Science, EarlyView.
The boron‐crosslinked gel polymer electrolyte (GPE_TMAB) enhances Li+ transport through Lewis‐acidic boron centers that selectively immobilize TFSI− anions, thereby enabling single‐ion conduction and promoting dendrite‐free lithium deposition. The engineered solvation structure drives the formation of an inorganic‐rich, mechanically robust SEI ...
