Molecular‐Level Modulation of Proton Transport via Electron‐Proton Coupling in Bio‐p‐n Junctions

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
We developed a pH‐sensing device capable of operating in biological environments. A biohybrid p–n junction was constructed using bacteriorhodopsin (bR) and the photoconductive polymer poly(3‐hexylthiophene) (P3HT). Under light illumination, the photocurrent exhibits distinct transitions across various pH gradients, demonstrating the system's high ...

Dual‐Mode Electrophoretic Displays Enabled by Quantum Dot‐Decorated PR48:2 Pigment Particles and TiO2 for All‐Weather Visibility, Excellent Bistability, and Enhanced Readability

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study presents a novel quantum dot electrophoretic display (QDEPD), which combines electro‐controlled reflection and optically‐triggered emission to achieve efficient multi‐modal switching within a single pixel. By incorporating multi‐component nanostructures, the system enhances functional integration and multi‐modal response capabilities.
