Modifying Electrochemical Doping in Light‐Emitting Electrochemical Cells With Gold Nanoparticles

Advanced Science, EarlyView.
This study shows that gold nanoparticles placed at an electrode can control how electrochemical doping occurs in organic electronic devices. Particularly, in light‐emitting electrochemical cells, by shifting the light‐emitting region, device efficiency is improved without altering the emissive material. This approach provides a simple and effective way

Prepolymerization Enables On‐Demand Viscosity Tuning for Xolography of Soft Hydrogels

Advanced Science, EarlyView.
A facile in situ prepolymerization strategy enables on‐demand viscosity tuning across three orders of magnitude without external thickeners, transforming low‐viscosity resins into printable formulations for Xolography. The approach suppresses sedimentation, lowers curing dose, enables high‐fidelity support‐free fabrication, and produces advanced ...
