A solvent extraction route is proposed to synthesize CaF(2) hollow spheres, which are formed by reversed micelles in a solvent extraction system templating the self-assembly of CaF(2) nanoparticles.
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
In this paper, the system reliability in the design stage and before production is improved. The proposed algorithm is based on the fact that the chosen structure should be practical in reality. First, possible structures for the system of interest are designed then the optimum structure is chosen for production. The proposed approach to select the optimal alternative is to determine the effe...
