I started with Hlatt is proportional to [absolute value of the product of charge on cation and anion] divided by the distance between their nuclei. Since the charge on F and Cl are the same, you could equate 2 proportionality equations to get Hlatt FeCl2/Hlatt FeF2 = 133 pm / 181 pm...
Phase evolution, diffusion kinetics and cell failure are critically influenced by surface-specific reactions. The reversibility of the conversion reaction is governed by topotactic cation diffusion through an invariant lattice of fluoride anions and the nucleation of metallic particles on semicoherent ...
the onset of anion diffusion, following cation shear displacement, is marked by an abrupt change in the pressure dependence of resistance through the transformation. the phase boundary determined in this study is in excellent agreement with the phase boundary determined by in-situ x-ray studies in...
The investigation of the two type vacancy defect energies in periclase (MgO); one is uncoupled cation and anion vacancies which is called as Schottky vacancies of cation and anion and another is the coupled cation-anion vacancy, is reported be a density functional theory (DFT) calculation. Scho...
A systematic theoretical DFT study of the bonding between the cation Fe3+ and the anion H2PO4− was carried out. By interesting in tetrahedral, bipyramid... ADET Abderrabba - 《Journal of Molecular Structure Theochem》 被引量: 0发表: 2005年 A DFT study of monophosphate complexes of iron...
On the other hand, the -K treatment increased Ca and Mg concentrations. -Ca caused an increase in Mg concentration and -Mg raised Ca concentration. These results may be due to compensation effects of cation absorption for the maintenance of the cation/anion balance. 展开 ...
