An analytical cluster wetting model is developed, based on minimization of an expression for the free energy, for solid-liquid equilibrium coexistence states in clusters. For given materials’ characteristic interfacial energies of the solid and liquid phases, the model relates the fraction of the solid-phase area wetted by the liquid to the volume fraction of the two phases. Equilibrium coexist...

Theoretical calculations are presented of solid-liquid equilibrium for linear quadrupolar molecules, focusing especially on the ratio of the triple point temperature to the critical temperature. The proposed treatment uses the hard quadrupolar dumbbell model as the reference system, and incorporates the effect of dispersion forces through a mean-field term. The reference system of quadrt/polar ...

We present a general algorithm for calculating the spatial variation of the shear viscosity and thermal conductivity through an equilibrium solid-liquid interface using the zero-flux version of the boundary fluctuation theory. In the case of an equilibrium interface between a high melting point Lennard-Jones solid and a low melting point Lennard-Jones liquid, we find that the transport coeffici...

Knowledge of solid–liquid equilibria (SLE) and vapor–liquid (VLE) for mixtures containing deep eutectic solvents (DESs) is paramount importance. We have conducted experiments to obtain additional data SLE systems then used the e-NRTL model predict VLE behavior in DESs comprised choline chloride (ChCl), sorbitol (S), water (W). The under investigation include three 2-component (S/W, ChCl/W, ChCl...

Due to the general population awareness about specific health hazards of synthetic chemical dyes, natural colorant materials have been gaining attention in past several years. Among them, ?-carotene is widely used as a soluble orange–red pigment food industry, while also presenting medical care benefits. Thus, considerable efforts dedicated development an efficient serial, cost effective and su...

Mass transfer during membrane formation by means of phase inversion for a polymeric system with both a solid-liquid and a liquid-liquid equilibrium was studied on the basis of the theory developed by Reuvers and Smolders. During the first moments of immersion in the coagulation bath, the concentrations at the interface between bath and film are governed by the virtual liquid-liquid equilibrium....

This work is mainly an investigation of some of the liquid-to-solid properties of pure benzene on a restricted domain of high pressures (20.6< or =P< or =102.9 MPa). Newly obtained equilibrium experimental data and recently developed analytical equation of state are exploited and compared with each other and with previous experimental data. Curves fitted to the pressure, volume discontinuity, a...

The case of a sorption process considered here involves a solid phase (sorbent) and a liquid phase (solvent, normally water) containing a dissolved species to be sorbed (sorbate, e.g. metal ions). Due to the higher ‘affinity’ of the sorbent for the sorbate species the latter is attracted into the solid and bound there by different mechanisms. This process takes place until an equilibrium is est...

Sea sand disruption method (SSDM) and matrix solid phase disruption (MSPD) were compared to solid-liquid extraction (SLE) for extraction of phenolic compounds from the Ficus carica leaves. Statistical treatment, ANOVA-single factor, was used to compare the extraction yields obtained by these methods, and for the majority of the extracted compounds, significantly higher yields were obtained by t...
