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

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
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 ...

Highly Permeable CeO2 Porous Hollow Microspheres with Multilevel Gas Channels for Rapid NH3 Gas Response and Recovery Performance

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
In this study, a series of highly permeable CeO2 porous hollow microspheres with multilevel gas channels and tunable pore sizes were first prepared via the hydrothermal method, achieving rapid response and fast recovery to ammonia gas. Fast response and recovery performance is highly significant for real‐time monitoring of NH3 gas due to the toxic and ...

Vacancy‐Type Defects in N‐Implanted GaN and Their Impact on Mg Diffusion Studied by a Monoenergetic Positron Beam

physica status solidi (b), Volume 263, Issue 11, November 2026.
Vertical GaN devices have been extensively studied, and Mg implantation with sequential N implantation has been reported as an ideal technique for fabricating p‐type regions in these devices. We used positron annihilation to study vacancy behavior during ultrahigh‐pressure annealing. It was found that the imbalanced formation of Ga‐ and N‐vacancies and

High‐Performance Self‐Powered Perovskite Photodiodes for Blue‐Light Detection Using Anisole‐Assisted Precursor Engineering

Small, Volume 22, Issue 62, 6 November 2026.
Anisole‐assisted precursor engineering provides a simple route to high‐quality perovskite films for self‐powered blue‐light photodetection. Anisole promotes grain growth and suppresses pinholes, reducing dark current while improving external quantum efficiency and detectivity.

Ethnic Groups' Access to State Power and Group Size

Economics &Politics, Volume 38, Issue 3, Page 790-803, November 2026.
ABSTRACT Ethnic‐based political inequality is widespread, yet its underlying drivers remain poorly understood. This paper shows that an ethnic group's relative size is a key correlate of its access to central executive power. Using data on 575 groups across 181 countries from 1946 to 2021, and restricting attention to non‐dominant groups, I document a ...
