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 ...

Photoemission Spectra from Al(111) Surface: Jellium and Band-Structure-Based Potentials
Physical Sciences ForumWe theoretically compare the photoemission spectra of an Al(111) surface under a short laser pulse using two unidimensional models: jellium and band-structure-based (BSB).

Nucleophilic Aromatic Substitution in the Gas Phase
Journal of Physical Organic Chemistry, Volume 39, Issue 11, November 2026.In this review, we highlight experimental studies of gas‐phase SNAr. Studying reactions in the gas phase provides invaluable information on intrinsic reactivity by eliminating the complications of solvent effects. Because SNAr is a fundamental reaction in chemical research and organic synthesis, understanding its underlying reactivity and mechanisms is

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.Abstract We improved the Model for Analyzing the Terrestrial Exosphere (MATE), a kinetic exosphere model, by incorporating solar radiation pressure and Coriolis force arising from the Earth's revolution around the Sun, in addition to Earth's gravity, to investigate their impacts on the terrestrial exospheric hydrogen density. Under constant and uniform

Quiet Time Ionosphere‐Thermosphere Predictability During Sudden Stratospheric Warmings in TIE‐GCM
Space Weather, Volume 24, Issue 11, November 2026.Abstract We investigate the predictability of the ionosphere‐thermosphere (IT) region during sudden stratospheric warmings (SSWs) by using subseasonal hindcasts in the Community Earth System Model, version 2 with the Whole Atmosphere Community Climate Model (CESM2 [WACCM6]) to force the lower boundary of the TIE‐GCM.
