This paper reports experimental data and the thermodynamic modeling of the liquid-liquid equilibrium systems with triacylglycerols, free fatty acids (obtained from olive oil), ethanol and water. The experimental data were fitted using the UNIQUAC model, in which absolute deviation of 1.28 % and root mean square deviation of 2.10 % between experimental and calculated mass fraction of the compone...

Living systems are the most important and most complex of nonequilibrium liquid crystalline systems. We check an experimental minimal model for macroscopic implications of this statement. To do this, we consider “living systems” in terms of three broken symmetries: 1. liquid crystalline (broken continuous symmetry); 2. chiral (broken mirror symmetry) and 3. non-equilibrium (broken time reversal...

Three-phase equilibrium in argon was obtained based on the thermodynamics of a perfect solid and a perfect liquid (v2). The equation of state (EOS) for a perfect solid was obtained from our previous study of a pure substance using spherical molecules. The EOS for a perfect liquid is a van der Waals EOS with the Carnahan-Starling repulsion term to explain 3-phase equilibrium. The Lennard-Jones p...

We study the interaction of a liquid drop with an elastic beam in the case where bending effects dominate. We use a variational approach to derive equilibrium equations for the system in the presence of gravity and in the presence or absence of contact line pinning. We show that the derived equilibrium equations for the beam subsystem reveal the external forces applied on the beam by the liquid...
