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 ...

Synthesis, structure and solvatochromism of 5-methyl-5-(3-or 4-substituted phenyl)hydantoins [PDF]

open access: yesJournal of the Serbian Chemical Society, 2009
Several 5-methyl-5-(3- or 4-substituted phenyl)hydantoins were prepared and their ultraviolet absorption spectra were recorded in the region 200-400 nm in twelve solvents of different polarity. The effect of solvent dipolarity/ polarizability and solvent/

Linear Solvation Energy Relationships in the Determination of Specificity and Selectivity of Stationary Phases [PDF]

open access: yesChromatographia, 2012
The retention of fifty structurally different compounds has been studied using linear solvation energy relationships. Investigations were performed with the use of six various stationary phases with two mobile phases (50/50 % v/v methanol/water and 50/50 % v/v acetonitrile/water).

Biorelevant Drug Solubility Enhancement Modeled by a Linear Solvation Energy Relationship [PDF]

open access: yesJournal of Pharmaceutical Sciences, 2018
It is for the pharmaceutical sciences of vital importance to understand how drugs are solubilized in biorelevant media. However, the complexity of fasted state simulated intestinal fluid (FaSSIF) has so far hampered adequate solubility modeling. The present study focuses on apparently neutral compounds at physiological pH and a linear free energy ...
