A Global Review of Microplastic Contamination in Groundwater: Empirical Evidence and Latin American Perspectives

Water and Environment Journal, EarlyView.
ABSTRACT The presence of microplastics (MPs) in groundwater has emerged as a significant concern due to their environmental impact and the threat they pose to vital water resources, groundwater being one of the most important freshwater sources in the world.

Toward Sustainable Carbonylation Reactions Enabled by CO Surrogates in Green Solvents

ChemSusChem, 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.

Photoinduced Copper‐Catalyzed para‐Selective C–H S‐Arylation of Benzylic Oxime Carbonates with Sulfenamides

Chinese Journal of Chemistry, Volume 44, Issue 13, Page 2160-2166, 1 July 2026.
We present a dual copper/photoredox catalytic system that enables the para‐selective C–H functionalization of benzyl alcohols with sulfenamides. This approach facilitates the para‐selective C–H sulfilimination of benzylic oxime carbonates through an orchestrated sequence involving photoinduced decarboxylation/dearomatization of oxime carbonates, copper‐

A Circular and Tacticity‐Independent Crystalline Mono‐Substituted Nylon‐6 Platform: Unexpected Large Positional Effects on Crystallizability and Performance

Angewandte Chemie, Volume 138, Issue 25, 15 June 2026.
Methyl substitution positions on the nylon‐6 backbone markedly affect crystallizability, thermomechanical properties, and recyclability of the resulting atactic nylon‐6 variants. While γ‐methyl substitution gives an amorphous nylon, all other four methyl‐substitution positions (α, β, δ, and ε) afford, unexpectedly, crystalline nylons, showing tacticity‐
