Recent efforts have demonstrated enhanced tailoring of material functionality with mixed anion materials, yet exploratory research with mixed anion chemistries is limited by the sensitivity of these materials to synthesis conditions. Synthesis of a particular metal oxynitride compound by traditional reactive annealing requires specific, limited ranges of both oxygen and nitrogen chemical potent...
Controlling nanocomposite composition and morphology is a vital step toward designing new and advanced materials. The current work presents the results of an experimental investigation of the use of mixed-phase reactants for the synthesis of nanocomposite materials. Gas-phase tetramethyltin was used as a precursor for tin dioxide (SnO2). Metal additives were introduced to the SnO2 synthesis sys...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
Herein, the synthesis of new quaternary layered Na-based oxides of the type Na x Mn y Ni z Fe0.1Mg0.1O2 (0.67≤ x ≤ 1.0; 0.5≤ y ≤ 0.7; 0.1≤ z ≤ 0.3) is described. The synthesis can be tuned to obtain P2- and O3-type as well as mixed P-/O-type phases as demonstrated by structural, morphological, and electrochemical properties characterization. Although all materials show good electrochemical perf...
