Abundance of atrazine degrading genes trzN versus atzA in soil cultures and in situ degradation rates

Pest Management Science, EarlyView.
Atrazine degradation in agricultural soils showed in situ half‐lives of 36–225 days. Field and laboratory results indicate active microbial hydrolysis driven mainly by trzN. Biphasic degradation sustains long‐term persistence, maintaining the potential for groundwater contamination despite reduced immediate leaching risk.

Photocatalytically Active Mechanically Interlocked Carbon Nanotubes

Small, EarlyView.
Mechanically interlocked CNTs (MINTs) are studied as heterogeneous photocatalysts. Two different motifs are presented, which own enhanced activity versus homogeneous systems at very low loadings, high TON, excellent recyclability, varied scope and no leaching.

Effects of humic electron mediators on reductive dechlorination of polychlorinated biphenyl by consortia enriched from terrestrial and marine environments

Frontiers in Microbiology
Humic electron mediators can facilitate the reductive dehalogenation of organohalogenated compounds by accelerating electron transfer. To investigate the effect of humic electron mediators on the microbial anaerobic reductive dechlorination of ...

Heavy‐Metal‐Free Colloidal Quantum Dots for Photocatalysis

Small, EarlyView.
Heavy‐metal‐free colloidal quantum dots provide sustainable photocatalytic platforms by combining tunable band structures, strong light absorption, and programmable surfaces/interfaces. This Review highlights how core/shell engineering, alloying, defect regulation, ligand design, and hybrid‐interface construction direct charge separation and ...

Visible‐light‐promoted catalyst‐free benzylic C‐H oxidation using molecular oxygen as a green oxidant

Smart Molecules, EarlyView.
A green and simple photo‐oxygenation of benzylic C‐H bond with molecular oxygen was developed for the preparation of a series of carbonyl compounds. The straightforward C‐H carbonylation strategy features catalyst‐ and additive‐free reaction conditions, only oxygen as a green oxidant, broad scope and scalable, and the simple‐operation nature.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Number and Position of Methoxy Substituents Govern Photophysics and Visible‐Light Photocatalysis in Earth‐Abundant Cu(I) Complexes

ChemSusChem, Volume 19, Issue 16, 27 August 2026.
The number and position of methoxy substituents provide a versatile molecular toolbox for tuning the photophysics and visible‐light photocatalytic performance of heteroleptic Cu(I) photosensitizers. Earth‐abundant Cu(I) photosensitizers are promising systems for visible‐light‐driven photocatalysis, but further design guidelines are required to relate ...
