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...

In this research, mechanical alloying was used to produce Ti-50Al, Ti-45Al-5Cr and Ti-45Al-5W (at%) alloys. The effect of ternary addition (Cr and W) on microstructure and production efficiency of TiAl alloy were investigated. Alloying was performed in a planetary mill and the milling time varying from 5 to 70h. The structural evaluation in these powders was done by X-ray diffraction (XRD) tech...

density, viscosity and refractive index of pure, binary and ternary mixtures of diethanolamine (dea) and methyl diethanolamine (mdea) with water have been measured at different temperatures from 288.15 k to 323.15 k at atmospheric pressure. also, this study presents the effects of mixture composition and temperature upon these thermo- physical properties. to measure the density and refractive i...

the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

A thermodynamic dataset was developed for the quinary Ti-Si-B-C-N system. The phase modeling includes all carbides, nitrides, carbonitrides, borides and silicdes which can be used as high temperature structural materials. The CALPHAD approach is used to calculate high-temperature phase reactions in the ternary and quaternary subsystems. The phase stabilities can be derived. All types of phase d...
