Artifact‐Minimizing Ultrathin Transparent Electrodes Fabricated via iCVD for In Vivo Optogenetic Stimulation and Neural Signal Monitoring of Primary Visual Cortex

Advanced Functional Materials, EarlyView.
We present ultrathin flexible transparent electrodes through iCVD‐enabled molecular control of 10 nm gold films on poly(dimethylaminomethylstyrene). In vivo validation demonstrated photoelectric artifact reduction vs. opaque electrodes and preservation of natural neural dynamics.

Constructing Ionic Fast Diffusion Channels on LiNi0.5Mn1.5O4 for Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
A dual‐modification strategy is developed for LNMO cathode, where bulk Ti doping stabilizes the oxygen framework and simultaneously drives the in situ formation of LaTi2O6 nano‐islands as ion diffusion channels on (111) surfaces, enabling high‐rate capacity (∼100 mAh g−1 at 30 C) and excellent cycling retention (87.8% after 1000 cycles).

Ion‑Mediated Structural Engineering of Hydrogel Interfaces for Tunable Mechanical and Analyte Diffusion Properties in Electrochemical Biosensors

Advanced Materials, EarlyView.
An ion‐mediated structural engineering strategy enables versatile modulation of PVA–Alginate hydrogel microstructure. We systematically examine how different ion combinations affect hydrogel mechanical properties and analyte diffusivity. Applying this novel strategy to hydrogel as the outer membrane in an electrochemical glucose biosensor allows ...
