In this work is examined whether it is possible to predict solid-liquid-vapor phase equilibrium of ternary systems used in the SAS processing by the Peng-Robinson equation of state coupled with the LCVM mixing rules and the UNIFAC method for excess Gibbs free energy calculation. The enthalpy of fusion and the melting point temperature are estimated by group contribution methods. The results sho...

The ternary perovskite system PbTiO3-Bi(Zn1/2Ti1/2)O3-Bi(Mg1/2Ti1/2)O3 was investigated in an attempt to capture the enhanced tetragonality of the PbTiO3-Bi(Zn1/2Ti1/2)O3 binary system at a morphotropic phase boundary (MPB) to improve piezoelectric performance. Results from the (1 x)[0.75 PbTiO3-0.25Bi(Zn1/2Ti1/2)O3]-(x)Bi(Mg1/2Ti1/2)O3 pseudo-binary solution indicate the formation of an MPB-ty...

We have studied liquid-liquid phase separation in aqueous ternary solutions of calf lens 'y-crystallin proteins. Specifically, we have examined two ternary systems containing ys-namely, yIVa with ys in water and yll with ys in water. For each system, the phase-separation temperatures (Tph(4)))a as a function of the overall protein volume fraction ¢b at various fixed compositions a (the "cloud-p...

Photo-induced phase transitions are characterized by the transformation from phase A to phase B through the absorption of photons. We have investigated the mechanism of the photo-induced phase transitions of four different ternary systems CiE4/alkane (i) with n = 8, 10, 12, 14; cyclohexane/H2O. We were interested in understanding the effect of chain length increase on the dynamics of transforma...

Uranium is a very toxic and radioactive element. Removal of uranium from wastewaters requires remediation technologies. Actual methods are costly and ineffective when uranium concentration is very low. Little is known about the enhancement of sorption of uranyl ions by phosphate ions on aluminosilicates. Here, we studied sorption of uranyl acetate on red clay in the presence of phosphates. The ...

8 The isothermal section of the La–B–C phase diagram at 1270 K has been investigated by 9 means of X-ray, neutron powder diffraction, microstructure and EPMA analyses. Eight ternary 10 compounds were found, and for six of them the crystal structures have been established. The 11 phase with the structure type of La5B2C6 has a broad homogeneity range described by the 12 formula La5(BC)x (5.6x8....

A~t~ct-~en~tion-de~ndent growth phenomena have been observed for liquid-phase epitaxial In,_Fa,As and other ternary and quatemary III-V semiconductors. The data cannot be explained by existing regular solution phase equilibria models. In this study we have used the quasi-regular solution formulation to derive a model which al= considers equilibrium between the growing surface and the bulk solid...

Substrates of III-V ternary compound semiconductors with variable bandgaps orlattice constants still remain very attractive for a variety of electronic, optoelec-tronic, and photovoltaic devices. However, the commercial technology for growinglarge-diameter, compositionally homogeneous, bulk III-V ternary crystals has notbeen fully developed. This chapter discusses the fundamenta...

Phase separation in lipid bilayers that include negatively charged lipids is examined experimentally. We observed phase-separated structures and determined the membrane miscibility temperatures in several binary and ternary lipid mixtures of unsaturated neutral lipid, dioleoylphosphatidylcholine (DOPC), saturated neutral lipid, dipalmitoylphosphatidylcholine (DPPC), unsaturated charged lipid, d...

in this work, ternary polymer blends based on polypropylene (pp)/ polyethylene terephthalate (pet) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (sebs) triblock copolymer and a reactive maleic anhydride grafted sebs (sebs-g-mah) at various compositions were prepared by co-rotating twin screw extruder. the effects of pet, sebs and sebs-g-mah compatibilizer on morphology of the blends were ex...
