Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.Abstract As large wildfires become more frequent and severe in North America due to heightened fuel aridity and fire weather conditions driven by anthropogenic climate change, wildfire smoke has an increasingly important influence on air quality. Transported smoke can impact urban boundary layer ozone (O3) directly, via the entrainment of O3 formed in ...

Advanced Science, Volume 13, Issue 44, 7 August 2026.This work constructed a tandem W−N−C center to simultaneously achieve the regulation of reaction pathways and optimization of charge separation efficiency. The Lewis‐acidic W6+ sites activated O2 to generate O2−$O_2^ - $, with enhanced charge separation via electronic modulation, steering U(VI) reduction down an efficient radical pathway.

From Cages to Sheets: Computational Elucidation of Methylaluminoxane Structure and Reactivity
ChemPlusChem, Volume 91, Issue 8, August 2026.Methylaluminoxane (MAO), the dominant cocatalyst in metallocene‐based olefin polymerization, has resisted structural characterization for decades. This review traces the computational journey from early cage and nanotube proposals to the identification of two‐dimensional aluminoxane sheets as the thermodynamically preferred motif, and how this ...

Counterion Effects on the Properties and Reactivity of Charged Photoredox Catalysts
ChemPhotoChem, Volume 10, Issue 8, August 2026.The choice of a counterion for a charged photocatalyst has long been overlooked. In this review, we summarize recent reports on counterion effects in photocatalysis, providing readers with a comprehensive theoretical understanding and synthetic applications for the use of a carefully chosen counterion. Electrostatic interactions represent the strongest

Food Science &Nutrition, Volume 14, Issue 8, August 2026.ZnO nanoparticles and MgSO4 synergistically alleviated drought‐induced damage in saffron. Foliar application improved relative water content and antioxidant enzyme activity. Photosynthetic performance and membrane stability were enhanced under water deficit. Moderate drought combined with ZnO‐NPs and MgSO4 maximized saffron productivity. ABSTRACT Water
