(CN)6as thecathode material. The relation between relative intensity of Raman spectra peak and the Ca(NO3)2concentration (Fig. 7c) shows that increasing the concentration of Ca(NO3)2can enhance the coordination number of Ca2+and NO3-, thus reducing the hydration number of Ca2+through ...

the fifth most abundant element in the earth's crust (3.6 per cent), occurring esp as forms of calcium carbonate. It is an essential constituent of bones and teeth and is used as a deoxidizer in steel. Symbol: Ca; atomic no: 20; atomic wt: 40.078; valency: 2; relative density: 1.55...
For trabecular bone, the following 3D parameters in the defined ROI were reported: bone volume (BV, mm3), tissue (cortical and marrow) volume (TV, mm3), relative bone volume over total volume (BV/TV, %), trabecular number (Tb.N, 1/mm), trabecular thickness (Tb.Th, mm), trabecular ...
Concentrations of copper and calcium in samples were determined by atomic absorption spectrophotometry. The concentration of copper uptaken and the calcium displaced from the gel at equilibrium was determined from the mass balance. At the end of each run, the spheres were collected, external water ...
Like other elements, a variety of processes alter the relative abundance of calcium isotopes.[28] The best studied of these processes is the mass-dependent fractionation of calcium isotopes that accompanies the precipitation of calcium minerals such as calcite, aragonite and apatite from solution. Lig...
