Structures are determined by two principal factors: the relative sizes of the ions and the ratio of the numbers of positive and negative ions in the compound. The size of the ion also depends upon the nature and magnitude of charge it possesses. As the positive charge increase...
The compound formed by this transfer is stabilized by the electrostatic attractions (ionic bonds) between the oppositely charged ions.Moving from the far right to the left on the periodic table, nonmetal elements often gain electrons to form anions with the same number of electrons as an atom...
structure is maintained during thisdissolution processand that the lost manganese ions on the manganese sites are replaced bylithium ions. In this manner, a disordered lithium-rich spinel of increased manganese oxidation state is formed. So, the complete dissolution reaction can be qualitatively ...
First-Principles Study on Structural Properties and 4f → 5d Transitions of Locally Charge-Compensated Ce3+ in CaF2 The structural properties and 4f → 5d transitions of Ce3+ in CaF2, with local charge compensation by an interstitial fluoride (Fi′) or an oxygen substitu... L Ning,C Wu,L...
Ionic liquids with a fluoride anion were used to make PHIG: 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim]BF4), 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF6), 1-butyl-4,5-dimethyl-imidazole tetrafluoroborate ([Bmmim]BF4), 1-butyl-3-methylimidazolium Bromide ([Bmim]Br) and...

Thus, particle surface charge is usually characterized using zeta potential (ZP), which is the electrostatic potential of the particles measured at the distance from the surface where ions are not bound to the particle (Moore et al., 2015). ...
