Additionally, one sample without gold was thermally treated at the same conditions (Cu0.5Mn0.5Fe2O4-TS300+400). Powder X-ray diffraction (XRD) patterns were collected on a TUR M62 diffractometer ... PowderCell-2.4 software and appropriate corrections for the instrumental broadening.Materials | Free Full-Text | In vitro Biocompatibility of ...Powder diffraction for all samples was measured on a STOE STADI P automated diffractometer, with CuK source, graphite monochromator, by using quartz sample holders; for the pure reagent, 10-25 mg of substance was used. The program PowderCell 2.2 was used for calculation of X-ray powder patterns on the basis of single crystal structure ...



Composition control of low-volatile solids through ...

Jan 10, 2012·Highlights This work is devoted to the composition control of solids with selective CVT method. Phase identity and non-stoichiometry of solids (GaSe, etc.) depend on CVT-temperatures. The interrelation between the properties of GaSe and CVT conditions is also found. For iodide transporting system the diagram of phase stability of solids is adjusted. High temperatures and Se-rich non ...

Treating the Public Water Supply - Department of Chemistry

In order for NaCl to be soluble, the Na + and Cl-ions must break free from the crystal-lattice structure of the solid. When the ions are in solution, they are surrounded by water molecules, and the ions are said to be solvated, or dissolved in an aqueous solution, denoted (aq).Hence, the process of dissolving a NaCl crystal can be described by the following chemical equation (Equation 1):

(IUCr) Lithium tetra­chlorido­aluminate, LiAlCl4: a new ...

Dissolving lithium chloride and aluminium chloride in boiling para- or meta-xylene and keeping the colourless solution at room temperature led to crystal growth of a new modification of lithium tetra­chlorido­aluminate, LiAlCl4, which represents a second modification (oP12, Pmn21) of the ternary salt besides the long known monoclinic form [LiAlCl4(mP24, P21/c); Mairesse et al. (1977).
