How many atoms of oxygen are there in 2.28 moles of Ca(NO_3)_2? How many moles of Ca(NO3)2 are needed to make 0.250 liters of a 0.200 M calcium nitrate solution? Calculate the mass percentage of nitrogen in 0.67 moles of Ca(NO3)2. Calculate the mass percentage of nitrogen...
The Ca/Sr atoms in the image do not exhibit displacement with regard to the unit cell center, which is expected since the matrix should belong to the nonpolar Acaa space group. On the other hand, we observe many nanometer-sized features along the (001) interface distributed randomly all ...
We have studied an internal friction (IF) peak at 400 K which appears when site A in manganite type ABO3 is partially substituted by Ca, Sr and Ba atoms. In the case of total substitution in CaMnO3, the 400 K peak is absent. The appearance and the increase of this peak measured...
These differences can be explained via the energy exchange that exists between the loaded Sn+4ions and the lattice locations of certain host atoms, consequently resulting in lattice deformation. This falls in line with the little peak-positioned shift at low Sn levels. Nevertheless, for perovskite...
we assume that the change in force constants is small, the short-range interactions are effective up to the second-neighbour ions and harmonic elastic forces hold the atoms together without any internal strains within the crystal. We thus express the crystal energy for a particular lattice separati...
In 1974, Molina and Rowland proposed in their Nature article that the chemically inert CFC could gradually be transported up to the ozone layer, there to be met by such intensive ultra-violet light that they would be separated into their constituents, notably chlorine atoms. They calculated that...
