Absorption Spectra of Protonated Corroles: Two Distinct Patterns Due to Peripheral Substitution Architecture

open access: yesOrganics, 2023
The origin of individual features in the ground state absorption spectra of two protonated corroles differing in the architecture of peripheral substitution (either Cm-aryl or Cb-alkyl) have been studied in detail with the ground state absorption ...

Highly Dispersed Vanadia Anchored on Protonated g-C3N4 as an Efficient and Selective Catalyst for the Hydroxylation of Benzene into Phenol

open access: yesMolecules, 2022
The direct hydroxylation of benzene is a green and economical-efficient alternative to the existing cumene process for phenol production. However, the undesired phenol selectivity at high benzene conversion hinders its wide application.

Proton Binding of Halloysite Nanotubes at Varied Ionic Strength: A Potentiometric Titration and Electrophoretic Mobility Study

open access: yesColloids and Interfaces
Proton binding (i.e., charging) isotherms of halloysite nanotubes (HNT) were determined from cycled acid-base potentiometric titrations in KCl solution at constant ionic strengths (0.01, 0.10, 1.00 mol dm−3). The isotherms measured in the pH cycle from 3

Solvent effects on glyphosate deprotonation: DFT theoretical studies

open access: yesChemical Physics Impact, 2023
To better understand the molecular structures of glyphosate in different solvents, we have studied several possible conformations, and their relative abundances, of glyphosate and its deprotonated forms, in acetone, acetonitrile, DMSO, water, ethanol ...
