In addition, from XPS results, the degree of ionicity of Nb [d.sub.5/2]-orbital was found a chemical shift of 1.3 eV, and for O 1sorbital were found two chemical shifts at 4.7 eV and 2.2 eV, which are attributed to the appearance of [Nb.sup.4+] and oxygen vacancies due to the RHT in [La.sub.0.05][Li.sub.0.85]Nb[O.sub.3] when compared to LiNb[O.sub.3], respectively.
They exhibit high aspect ratio unit cell that is similar to MAX phases with alternating planes containing stiff carbidic and boridic bonds with a high degree of ionicity providing the high stiffness and hardness, while metallic bonds offer moderate ductility.
However, this polysiloxane backbone is susceptible to attack from acids or bases and can be degraded even at relatively low temperatures, due to the ionicity of Si-O bonds (12).

Given that CROSS is based on ionicity of the involved cations, it would appear appropriate that coefficients of dispersibility could be used to further inform clay colloidal behaviour in a soil system and derive an equation on this basis.
Contrast was subdivided on the basis of ionicity into ionic and nonionic; osmolarity into high osmolal contrast media (HOCM) and low osmolal contrast media (LOCM); structure into monomer and dimer.
The molecular structure, whether cyclic or linear, and the ionicity determine the stability of Gd chelates.

In recent years, various experimental and theoretical works have been done to generalize the trends in the ionicity ([f.sub.i]) and refractive index (n) of ternary chalcopyrite structures [A.sup.I][B.sup.III][C.sub.2.sup.VI] and AIIBIVC2V (Gorai and Mahata, 2010; Kumar et al, 1994; Neumann, 1987, 1985).
