Fundamental challenges and opportunities for preparative supercritical fluid chromatography.

TL;DR: A clearer understanding of the physico-chemical behavior of supercritical fluids in preparative chromatographic columns under nonlinear conditions is still needed, which seems to be the main obstacle to the establishment of SFC as a sustainable separation tool.

Structural changes in W/O triton X-100/cyclohexane-hexanol/water microemulsions probed by a fluorescent drug Piroxicam

TL;DR: In this article, the photophysics of a fluorescent drug Piroxicam was used to probe the intramicellar region of nonionic microemulsions of Triton X-100/cyclohexane/water, using both steady-state and transient (picosecond resolution) techniques.

Solvatochromism in pure and binary solvent mixtures: effects of the molecular structure of the zwitterionic probe

TL;DR: In this article, the solvatochromic behavior of 2,6-dichloro-4-(2,4-6-triphenyl-1-pyridinio)phenolate (WB) was studied by UV-visible spectrophotometry in 32 pure solvents, in binary mixtures of 1-butanol-cyclohexane (BuOH-Cyhx), and of water with methanol, ethanol, 1-propanol, 2-butoxyethanol (2-BE), acetonitrile

Characterization of some normal-phase liquid chromatographic stationary phases based on linear solvation energy relationships

TL;DR: In this article, a number of normal-phase liquid chromatography (NP-LC) stationary phases were characterized by estimating characteristic interaction constants for the stationary phases based on linear solvation energy relationships.

Local compositions in thermodynamic excess functions for liquid mixtures

TL;DR: In this paper, a new equation based on Scott's two-liquid model and on an assumption of nonrandomness similar to that used by Wilson is derived, which gives an excellent representation of many types of liquid mixtures.

Statistical thermodynamics of liquid mixtures: A new expression for the excess Gibbs energy of partly or completely miscible systems

TL;DR: The UNIQUAC equation as discussed by the authors is a semi-theoretical equation for the excess Gibbs energy of a liquid mixture, which is generalized through introduction of the local area fraction as the primary concentration variable.

Solute–solute interactions in water. II. An analysis through the Kirkwood–Buff integrals for 14 organic solutes

TL;DR: In this paper, the Kirkwood-Buff integrals Gij defined by Gij =∫∞0 [gij(r) −1] 4πr2dr=f(a,V,K), (i=1,2; j= 1,2), have been calculated in the whole concentration range.
