Effect of molar ratio and calcination temperature on particle size of CeO2/-Al2O3 nanocomposites prepared via reverse micelle process
A porous composite of cerium oxide and gama aluminum oxide pigments were prepared via sol-gel processing controlled within reverse micelles of nonionic surfactant Triton X-114 in cyclohexane. The precursor in heated at several calcinations temperature between 823 to 1123K. This process includes three steps. In the first step of preparation the ceria sol was prepared. In the second step, cyclohe...
متن کاملEffect of Solvents on the Synthesis of SrAl2O4 Nanoparticles by Reverse Micelle Process
Three types of solvents with different polarity (cyclohexane, toluene and benzene), a nonionic surfactant Span 40 were used to prepare strontium aluminate (SrAl2O4) spinel nanoparticles by a reverse micelle method. The structure of SrAl2O4 nanoparticles was characterized by X-ray diffraction (XRD). The morphology and size of the synthesized materials were studied using field emission scanning e...
متن کاملReverse Micelle Based Formation of BaCO3 Nanowires
A reverse micelle based approach is reported for the synthesis of BaCO3 nanowires with lengths up to 100 μm and diameters as small as 10-30 nm, each of which is a continuous single crystal with the c-axis along the wire length axis. The synthesis is achieved by the reaction of barium and carbonate ions solubilized in the polar cores of nonionic reverse micelles of C12E4 (tetraethylene glycol mo...
متن کاملThermodynamics of micelle formation: prediction of micelle size and size distribution.
This paper presents a simple theory for the calculation of micelle size and other properties of micelleforming systems. The theory is based on the separate estimation of the components of the free energy arising from hydrophobic attraction and from head group repulsion, each as a function of micelle size. The difficult problem of an a priori calculation of the repulsive factor is circumvented b...
متن کاملInfluence of surfactant structure on reverse micelle size and charge for nonpolar electrophoretic inks.
Electrophoretic inks, which are suspensions of colorant particles that are controllably concentrated and dispersed by applied electric fields, are the leading commercial technology for high-quality reflective displays. Extending the state of the art for high-fidelity color in these displays requires improved understanding and control of the colloidal systems. In these inks, reverse micelles in ...
