Rapid Detection of Plasticizer Migration From UV‐Aged PVC Films by DART‐HRMS

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale The migration of phthalate plasticizers from high‐volume polymers, such as poly(vinyl chloride) (PVC), raises significant toxicological concerns, particularly when materials are subjected to aging and environmental stress. As traditional monitoring techniques rely on time‐consuming solvent extraction and chromatographic methods that ...

Mechanism of the Photodecomposition of Stable Triarylmethyl Radicals

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Photolysis of luminescent chlorinated trityl radicals was studied with density functional theory and the decomposition products were isolated and characterized. It proceeds by a 5‐electron electrocyclization then a 1,8‐sigmatropic chloride shift, forming non‐emissive, less stable fluorenyl radicals.

What Is a Polyolefin? A Critical Overview of Ethylene Copolymers Used as Solar Photovoltaic Module Encapsulants

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 4, Page 367-395, April 2026.
Polyolefin encapsulants are gaining dominance in PV modules, yet confusion persists around PO, POE, and TPO definitions. This study clarifies terminology, reviews materials, and properties and proposes a taxonomy to improve understanding, communication, and reliability in solar module manufacturing.

Relative Humidity Influences Aureobasidium pullulans Degradation of Polyester Polyurethane Foam

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
The plant pathogen Aureobasidium pullulans' ability to degrade polyurethane foam is impacted by Equilibrium Relative Humidity (ERH). These impacts can be observed through foam weight loss, scanning electron microscopy (SEM), fungal growth, and cutinase gene expression.

Acid‐ and Nucleophile‐Gated Photoisomerization of Phosphaindirubin

Angewandte Chemie, Volume 138, Issue 10, 2 March 2026.
Triply gated isomerization: In polar solvents, a phosphorus‐containing indirubin photoswitch undergoes visible‐light‐driven Z→E isomerization only when protonated, and reverts thermally via nucleophile‐catalyzed back‐isomerization. This three‐way control by light, acid, and nucleophile enables reversible photoisomerization.
