A cautionary tale of basic azo photoswitching in dichloromethane finally explained

open access: yesCommunications Chemistry
Many studies of azobenzene photoswitches are carried out in polar aprotic solvents as a first principles characterization of thermal isomerization. Among the most convenient polar aprotic solvents are chlorinated hydrocarbons, such as DCM.

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Carbonylation reactions offer a sustainable route to valuable carbonyl compounds. This review highlights methodologies that exploit carbonylative coupling to drastically enhance process sustainability, avoiding the direct use of CO through CO surrogates and promoting syntheses in green solvents potentially derived from renewable and sustainable sources.

Cosolvent‐Enhanced Dissolution of Long‐Chain Polyamides: Toward Room‐Temperature Material Recycling of Sustainable Composites

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
Long‐chain polyamides (PAs) such as bio‐derived PA11 and conventional PA12 are difficult to dissolve at room temperature, hindering facile recycling by dissolution‐based methods. This work shows that adding a weak H‐bonding cosolvent to formic acid can rapidly dissolve long‐chain PAs at room temperature by balancing H‐bonding and dispersive ...

Release rates of chlorinated hydrocarbons from contaminated sediments

open access: yes, 1992
The release rates of chlorinated hydrocarbons from contaminated intertidal sediments were measured with an apparatus that consists of a microcosm with calibrated flow regime, a continuous counterflow liquid-liquid extractor, and an aerator column ...

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 7, Page 3593-3617, July 2026.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...
