Tailoring High‐Valent Iron‐Oxo Species Redox via Extended π‐Fe3d–O2p Orbital Overlapping Toward Chemical‐Efficient Water Purification

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We address the long‐standing challenge of reactivity–selectivity trade‐off by precisely tuning the redox properties of Fe(IV), rather than simply accelerating its formation, to enable chemically efficient and low‐emission water treatment. ABSTRACT High‐valent iron oxo species (Fe(IV)) are attractive for wastewater treatment because of their high ...

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Bacterial composition of Polygenis (Polygenis) bohlsi bohlsi (Wagner, 1901) (Siphonaptera: Rhopalopsyllidae) associated with Thrichomys fosteri (Rodentia: Echimyidae) in the Brazilian Pantanal wetland

Medical and Veterinary Entomology, EarlyView.
This study characterizes the bacteriome of Polygenis (Polygenis) bohlsi bohlsi fleas collected from free‐living Thrichomys fosteri in the Pantanal region of Brazil. The bacterial microbiota associated with male fleas exhibited greater phylogenetic diversity, and the overall community structure differed between the flea sexes.

A Gamma Ray–Induced Dwarf and Early Mutant of Brassica juncea With Favourable Traits for Developing High‐Yielding, Dwarf/Semi‐Dwarf Genotypes

Plant Breeding, EarlyView.
ABSTRACT Introduction of dwarfism to cereals has set a new paradigm in crop improvement programmes. To date, very little progress has been made in the development of high‐yielding dwarf/semi‐dwarf genotypes in oilseed Brassica. Previous attempts using induced mutagenesis employed in the induction of dwarfism in Brassica crops yielded limited success ...

Simultaneous Determination of Clomazone, Diuron and Hexazinone in Wastewater From Agrochemical Formulators by High‐Performance Liquid Chromatography

Water and Environment Journal, EarlyView.
ABSTRACT Agrochemical companies face significant challenges in cleaning their equipment due to the high levels of residual pesticide contamination. This study aimed to develop and validate an HPLC‐UV/DAD method for the simultaneous determination of clomazone, diuron and hexazinone in wastewater generated during the cleaning of formulation equipment ...
