General Relationship Between Gibbs Energies and Enthalpies of Solvation, Vaporization, and Complexation for Molecular Compounds [PDF]

open access: yesMolecules
The Gibbs equation describes the relationship between the enthalpy (∆H), entropy (∆S), and Gibbs energy (∆G) changes in physicochemical processes: ∆G = ∆H − T∆S.

Ion–solvent chemistry in lithium battery electrolytes: From mono-solvent to multi-solvent complexes

open access: yesFundamental Research, 2021
The building of safe and high energy-density lithium batteries is strongly dependent on the electrochemical performance of working electrolytes, in which ion–solvent interactions play a vital role. Herein, the ion–solvent chemistry is developed from mono-

Rapid determination of serum albumin partition coefficients using affinity chromatography

open access: yesEnvironmental Advances, 2022
Sorption to serum albumin is essential for characterizing the distribution of chemicals in organisms. It impacts the concentration of the freely dissolved chemical in vivo and in vitro, and needs to be considered when effect concentrations at the target ...

Solvent influence on absorption spectra of food azo dyes

open access: yesZaštita Materijala, 2019
The solvent influence on absorption spectra of food azo dyes was examined by the method of Linear Solvation Energy Relationships (LSER). For this purpose, six azo dyes were used: tartrazine (E 102), ponceau 4R (E 124), azorubin (E 122), brilliant black ...
