The feasibility of a novel multivessel batch distillation–decanter hybrid for simultaneous separation of ternary heterogeneous azeotropic mixtures is addressed both theoretically and by simulations. The multivessel column is operated as a closed system without product withdrawal and the three components are accumulated in the vessels during one closed operation. The closed mode (total reflux) o...

Phosphatidylcholine/sphingomyelin/cholesterol (PC/SM/CHOL) ternary mixtures were investigated using differential scanning calorimetry (DSC). Palmitoyl-oleoyl phosphatidylcholine (POPC) and palmitoyl-docosahexaenoyl (-3) phosphatidylcholine (PDPC) were used to study the effect of the number of double bonds at the sn-2 position in PC molecule on the phase behavior of PC/SM/CHOL mixtures. The PDP...

In the first part of the present research, an R290/R600 mixture was tested as a drop-in substitute in a 20cubic-feet, single-evaporator, autodefrost, topmount, conventional domestic refrigerator/freezer. All the hardware remained the same, only the capillary tube was lengthened to achieve the optimum performance. The best result with an optimized R290/R600 blend was 6% savings compared to the b...

The dynamics of a ternary polymer mixture consisting of either homopolymers A and B, or diblock copolymers A-B, in a matrix of homopolymers C, is studied using the random phase approximation and assuming incompressibility. The relaxation frequencies and the amplitudes of the modes in dynamic scattering on such a mixture have been calculated as a function of the wave number q. In addition, the f...

– A lattice Boltzmann model is introduced which simulates oil–water–surfactant mixtures. The model is based on a Ginzburg-Landau free energy with two scalar order parameters. Diffusive and hydrodynamic transport is included. Results are presented showing how the surfactant diffuses to the oil–water interfaces thus lowering the surface tension and leading to spontaneous emulsification. The rate ...

The objective of the present study was to develop a physiologically based pharmacokinetic (PBPK) model for a ternary mixture of alkyl benzenes [toluene (TOL), m-xylene (XYL), and ethylbenzene (EBZ)] in rats and humans. The approach involved the development of the mixture PBPK model in the rat and extrapolation to humans by substituting rat physiological parameters and blood:air partition coeffi...

It is shown that good estimates of the activity of cholesterol in phosphatidylcholine-cholesterol mixed model membranes are obtained by examining the orientational order parameter S of cholestane spin probe (CSL) that is obtained from electron spin resonance by spectral simulation. By introducing thermodynamic stability conditions of liquid mixtures, the variation of activity (or S) as a functi...

Abstract:  In this study, the change in the crystalline structure of gas hydrate was predicted for ternary mixture of methane-ethane-water. For this purpose, the tangent plane distance (TPD) minimization method was used. First, the calculations were performed for the binary mixtures of methane-water and ethane-water as the gas and liquid phases. The results show that for a binary mixture of th...

Clarithromycin (CLA), a broad-spectrum macrolide, is a poorly soluble drug with dissolution rate limited absorption. The aim of this investigation was to prepare CLA nanoparticles from a ternary ground mixture in the presence of sodium lauryl sulfate (SLS) and polyvinyl pyrrolidone (PVP) as co-grinding water-soluble compounds, in order to improve the drug dissolution rate. Different weight rati...
