When Dark States Become Bright: Vibronic Intensity Borrowing in Triplet 2,6‐Dichloro‐4‐Hydroxyphenylnitrene

Journal of Physical Organic Chemistry, Volume 39, Issue 7, July 2026.
Irradiation of 4‐azido‐2,6‐dichlorophenol in cryogenic matrices generates triplet 2,6‐dichloro‐4‐hydroxyphenylnitrene. Vibronically structured absorption enables extension of a formally forbidden transition into the visible region (up to 500 nm). Analyses based on NICS(1.7)zz, ACID, HOMA, MCI, and spin density reveal magnetically induced ring currents ...

Integrating DynamiCROP model and risk assessment for pesticide residues in spinach: Implications for food safety

Pest Management Science, Volume 82, Issue 7, Page 7154-7163, July 2026.
This study adapted and validated the dynamiCROP model for spinach, a leafy vegetable not previously included in its standard framework. The findings confirm that model‐predicted pesticide concentrations, when integrated into hazard quotient (HQ) calculations, can effectively support dietary risk assessment.

Antioxidants in Plant‐Based Food Matrices: From Structure–Activity and Degradation Kinetics to Formulation Design

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 4, July 2026.
ABSTRACT Plant‐based antioxidants are widely incorporated into foods to retard oxidative deterioration and to deliver health‐related benefits. Yet, their in‐product and in vivo performance frequently diverges from predictions based on solution‐phase chemical assays, because matrix interactions, processing history, and host metabolism reshape both ...

Nitrate Photolysis in the Upper Boundary Layer as a Daytime Missing Source of HONO: Revealed by In Situ Airship Measurements and Modeling

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The missing source of nitrous acid (HONO) is a key uncertainty in understanding atmospheric chemistry in the troposphere. Particulate nitrate photolysis has been proposed as a potential source of daytime HONO, but its contribution remains poorly constrained, with even less attention paid to the impact of nitrate aloft. Here, we investigate the

Influence of Secondary Brown Carbon Aerosol Lifetime on Radiative Properties

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Brown carbon (BrC), a light‐absorbing organic aerosol, exhibits higher absorption coefficients at short wavelengths. Partial BrC can be formed via secondary process. In this study, we isolated the secondary BrC (σabs,sec BrC) between urban surface and mountain stations (which receive surface pollutants during convective mixing) to investigate ...
