Atomically Dispersed Fe‐Modified SnS for Sn‐Centered Peroxymonosulfate Activation Toward Acetaminophen Degradation

Advanced Science, EarlyView.
Atomically dispersed Fe regulates the local electronic environment and surface properties of SnS, while PMS preferentially coordinates to Sn through Sn–O interaction. Fe incorporation further enhances the Sn–OPMS interfacial interaction, facilitating Sn‐centered PMS activation and the generation of SO4•−/•OH for APAP degradation, thereby clarifying the

Aumento del contenido de ácidos húmicos en un carbón de bajo rango a través de la oxidación con aire y con peróxido de hidrogeno o ácido nítrico

Química Nova, 2013
Low-rank coals are an important source of humic acids, which are important in retention processes of water and nutrients in plants. In this study coal samples of Montelibano, Colombia, were oxidized with air at different temperatures and subsequently ...

Soil pH Amelioration Synergizes Carbon Accrual with Yield Gains Under Organic Substitution

Advanced Science, EarlyView.
Soil pH shifts towards neutrality in both acidic and alkaline soils under organic substitution. A global synthesis links pH amelioration to soil organic carbon accrual through enhanced microbial biomass after accounting for added organic carbon and its interaction with pH. This pH amelioration‐shared soil organic carbon accrual accounts for 5.1–8.6% of

Electronic‐State Programming of Ultrasmall CeO2 Switches H2O2 Activation From Radical to Bio‐Inspired Nonradical 1O2 Generation for Combating Antibiotic Resistance

Advanced Science, EarlyView.
A scalable synthesis of carbon‐supported ultrasmall CeO2 nanoparticles with precisely tunable Ce electron density is reported. Electron‐lean Ce sites activate H2O2 exclusively via a nonradical pathway, enabling efficient HOBr and 1O2 production analogous to bromoperoxidase for contaminant and antibiotic resistance removal.

Impact of humic acids on methane emissions from microplastic contaminated paddy soils

, 2023
reservedPolyvinyl chloride (PVC) microplastics (MP) have been shown to increase methane emissions from paddy soils. Redox-active humic acids (HA) were also found to be enriched in microplastic contaminated soils, and these compounds have the potential to

Heavy metal distribution between fractions of humic substances in heavily polluted soils

Plant, Soil and Environment, 2004
Soil organic matter is important in controlling heavy metal behaviour in soils. This study aims to determine the distribution of organically bound Cd, Pb, and Zn between humic and fulvic acids in 20 samples of heavily polluted Fluvisols.

EFFECT OF SOME HUMIC ACIDS ON WHEAT PLANT GROWN IN DIFFERENT SOILS [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2006
A pot experiment was conducted to study the effect of four humic acids extracted from different composts on wheat plant (Triticum aestivum L. cv. Yecora rojo) grown in a highly calcareous loamy sand soil (CaC03=28%) and in noncalcareous sandy soil ...
