Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3

Advanced Functional Materials, Volume 36, Issue 13, 12 February 2026.
Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...

Deuteration Induced Electron‐Phonon Coupling Modulation: Suppressing Energy Dissipation and Enhancing Carrier Separation in Organic Photocatalysis

Advanced Science, Volume 13, Issue 7, 3 February 2026.
During charge transport, photogenerated carriers exchange energy with lattice vibrations, influencing photocatalytic performance. The deuteration strategy enhances exciton dissociation and suppresses non‐radiative energy loss, significantly improving photocatalytic hydrogen evolution.

Luminescent Chiral Molecular Glasses by Melt‐Quenching Enantiopure BINAP

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Melt‐quenching of enantiopure BINAP yields transparent chiral molecular glasses that retain axial chirality and display blue‐shifted luminescence together with strongly enhanced circularly polarized emission with dissymmetry factors |glum| of ≈10−2.

Push–Pull Bridged Stilbenes as Small Solvatochromic Aggregation‐Induced Emission Luminogen: Design and Excited‐state Deactivation Dynamics

Aggregate, Volume 7, Issue 2, February 2026.
A push–pull bridged stilbene (DpCBS[7]) demonstrates both solvatochromism and aggregation‐induced emission (AIE) within a compact molecular framework. Despite polarity‐dependent emission shifts, its fluorescence quantum yield remains low in solution due to ultrafast internal conversion.

The Vascular‐Immune Cells Crosstalk and Microenvironment in Pulmonary Hypertension

Comprehensive Physiology, Volume 16, Issue 1, February 2026.
This review synthesizes current evidence showing how vascular–immune cell crosstalk and microenvironmental cues shape pulmonary vascular remodeling in pulmonary hypertension. We provide an integrative perspective that positions disrupted cellular communication as a central driver of disease progression and a promising source of future therapeutic ...
