Conceptual Density Functional Theory for Temporary Anions Stabilized by Scaled Nuclear Charges [PDF]

, 2022
The charge stabilization method has often been used before for obtaining energies of temporary anions. Herein, we combine this method for the first time with conceptual density functional theory and quantum theory of atoms in molecules, by extending it ...

Unraveling the Role of Humic Acid in the Oxidation of Phenolic Contaminants by Soluble Manganese Oxo-Anions [PDF]

Humic acid (HA) is ubiquitous in natural aquatic environments and effectively accelerates decontamination by permanganate (Mn(VII)). However, the detailed mechanism remains uncertain. Herein, the intrinsic mechanisms of HA’s impact on phenolics oxidation
