Mechanisms of goethite dissolution in the presence of desferrioxamine B and Suwannee River fulvic acid at pH 6.5 [PDF]

, 2013
Siderophores are Fe3+ specific low MW chelating ligands secreted by microorganisms in response to Fe stress. Low MW organic acids such as oxalate have been shown to enhance siderophore mediated dissolution of Fe3+ oxides.

Environmental Transformation and Trophic Transfer of Engineered Nanomaterials in the Agri‐Food Chain and Implications for human Health

ChemFoodChem, EarlyView.
ABSTRACT Engineered nanomaterials (ENMs) are increasingly applied in agriculture to improve crop yield, nutrient efficiency, and food quality. This study examines the environmental transformation of ENMs, their uptake in plants, and their transfer across the agri‐food chain leading to human exposure.

Wurtzite‐Chalcopyrite Crystal Polymorphism in CuGaS2 Nanoparticles Dictates the Localized Surface Plasmon Resonance

Chemistry – A European Journal, EarlyView.
Crystal phase‐ and size‐selective synthesis of chalcopyrite and wurtzite‐type CuGaS2 NPs was successfully achieved. They exhibited clear LSPR in the NIR region. The extinction coefficient of chalcopyrite was three times higher than that of wurtzite due to its greater symmetry and dipole moment. These results will enable precise control of the plasmonic

Composition characteristics and metal binding capacity of dissolved organic matter in the agriculture‐dominated Tuhai River

River
An essential part of river ecosystems, dissolved organic matter (DOM) has an enormous effect on the transport and variability of heavy metals. Nonetheless, our understanding of how the DOM affects heavy metal behavior in agricultural rivers remains ...

Characterization of Humic Substances by Functional Groups and Spectroscopic Methods

, 2017
Humic substances are often described as coiled, long chain molecules of two or three dimensional cross linked macromolecules which may vary in molecular weight depending on type of humic acid and method of measurement (Stevenson, 1994).

Structure-Property-Function Relationship in Humic Substances to Explain the Biological Activity in Plants

Scientific Reports, 2016
Knowledge of the structure-property-function relationship of humic substances (HSs) is key for understanding their role in soil. Despite progress, studies on this topic are still under discussion.

Optimization of a reactor for biostimulant production with emphasis on the economic aspects of hydrolysis

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Biostimulants are increasingly used in agriculture to promote plant growth, improve stress tolerance, and support sustainable farming practices. One common method of production is chemical hydrolysis of protein‐rich waste, such as tannery by‐products, offering an economical and eco‐friendly alternative to conventional raw materials.

Utilizing Coal Ash and Humic Substances as Soil Ameliorant on Reclaimed Post-Mining Land [PDF]

, 2014
Coal ash and humic substances can be used as soil ameliorant in the reclamation of formerly mined land. Due to its high pH and nutrients content, coal ash can be used to improve the chemical properties of the soil, such as increasing of pH, and ...
