The SAFT-γ Mie group-contribution equation of state is used to represent the fluid-phase behavior aqueous solutions a variety linear, branched, and cyclic amines. New group interactions are developed in order model mixtures interest, including like unlike between alkyl primary, secondary, tertiary amine groups (NH2, NH, N), secondary (cNH, cN), methine-amine (cCHNH, cCHN) with water (H2O). grou...

The topology and the geometry of a surface play a fundamental role in determining the equilibrium configurations of thin films of liquid crystals. We propose here a theoretical analysis of a recently introduced surface Frank energy, in the case of two-dimensional nematic liquid crystals coating a toroidal particle. Our aim is to show how a different modeling of the effect of extrinsic curvature...

This paper represents a continuation of the series concerning experimental determination of vapour–liquid equilibria (VLE) in diluted polymer + solvent systems. In the previous papers we dealt with the polymeric flow improvers + toluene, hexane, chloroform1,2, poly(acrylic acid) + water3, poly(methyl methacrylate) + acetone3, and poly(methyl methacrylate) + 2-butanone4 systems. The aim of this ...
