Vasylyev et al. reported titanium and oxide-phosphonate porous nanospherical particles by non-hydrolytic condensation of water-insoluble arylphosphoric acid (tetrakis-1,3,5,7-(4-phosphonatophenyl) adamantane) and titanium isopropoxide [26].
Xray photoelectron spectroscopy (XPS) measurements were performed on a Kratos Axis Ultra DLD (delay line detector) spectrometer equipped with a monochromatic Al-Kα X-ray source (1486.6 eV).
The chemical compositions of Ti and P were analyzed by inductively coupled plasma (ICP) emission spectroscopy on a Thermo Jarrell-Ash ICP-9000 (N+M) spectrometer, and C, N and H were analyzed on a Vario-EL elemental analyzer.

(a) (b) Recent statistical analysis of the distribution of grain boundary planes in polycrystalline MgO [77-79], SrTiO3 [77,80,81], MgAl2O4 [77], TiO2 [77], and Al [77] using electron backscattered diffraction (EBSD) mapping showed that the low index grain boundaries were the most numerous.

Experimental To obtain the ZnAl2O4 catalytic support were used the following materials: aluminum nitrate [Al(NO3)3.9H2O] and zinc nitrate [Zn(NO3)2.6H2O] as oxidants, and the fuels aniline (C6H5NH2), carbohydrazide (CH6N4O), and glycine (NH2CH2COOH) as reducing agents, all of them with purity above 97%.
Singh et al. [15], when synthesized powders ZnAl2O4 via combustion reaction using urea as fuel, also observed a liberation of large amounts of gas, achieving a maximum temperature greater than those observed in the present study, reaching a value of approximately 1500°C.
Singh et al. [15] when synthesized the ZnAl2O4 spinel by combustion reaction using urea as fuel observed by textural analysis the obtaining of a material with mesoporous characteristic, and with similar physical properties, i.e. surface area of 32.9 m2/g, pore diameter of 19.04 Å and pore volume of 0.045 cm3/g.
According to Singh et al. [15], this non-uniformity in the shape could be related to the non-uniformity in the distribution of temperature and mass flow in the combustion flame.

Li Shun et al [16] found that when the Mw was too high or too low, it will reduce adsorption amount to the surface of cement particles.
Li Chongzhi et al [18] introduced polyoxyethylene chain to the backbone.
K.Yamada[20]et al found a shorter backbone chain length gave more fluidity at the same dosage, and a slightly longer setting time.
