The initial solution composition was calculated based on the total valence of oxidizing and reducing reagents using the propellants and explosives chemistry concepts [7].
The X-ray diffraction curves showed the presence of main peaks characteristic of the inverse spinel structure, evidenced by the appearance of the main peak 2θ = 35.5º as crystallographic record JCPDF 52-0278.
This excellent performance of Ni0.5Zn0.5Fe2O4 nanocatalyst for biodiesel conversion can be mainly attributed to the synergism between the oxides Ni, Zn and Fe that make up the nanoferrite, that is, whether the cohesion (chemistry and physics) or simultaneous association of cooperation between the elements of the material.

HA is a mineral in the apatite family with chemical formula (Ca10(PO4)6(OH)2, molecular structure is hexagonal shape with about 20x80x5 nanometers dimensions, molecular weight 1004.8, density 3.16 g/cm3, unit cell: a = 9.432 and c = 6.881, mol ratio of calcium phosphorus (Ca:P) = 10:6 [3].
Now various types of bioceramic and bioglass are popular use as human bone substitute, particularly HA which has the molecular chemistry as same as major human bone mineral.For example, Albee et al. [12] succeeded in usingthe first of bioceramic calcium phosphate in the patients.

Synthesis and Characterization of 3-Difluoroaminomethyl-3-methyl Oxetane and Its Homopolymer Li Huan1,a, Pan Renming2,b*, Wang Wanjun3,c, Zhang Luyao4,d 1,2Chemical Engineering School, Nanjing University of Science and Technology, Nanjing 210094, China 3Shanghai Institute of Organic Chemistry, Chinese Academy of Science, Shanghai 200032, China 4Gansu Yinguang Chemical Industry Group Co.
The structure of PDFAMO was characterized by 1H and 19F NMR.
Affected by the unstable structures, difluoroamino compounds have not been practically use until 1980th, while Chapman et al [2] found the similar cyclic structure with cyclotrimethylenetrinitramine (RDX) or cyclotetramethylenetetranitroamine (HMX) to keep difluoroamino group stable.
This phenomenon could be due to the strong acidity of these Lewis acids which induced the dissociation of fluorine and reduced the structure stability of difluoroamino groups.

The structure of the prepared oxygen carrier was characterized by scanning electron microscope (SEM) and an X-ray diffractometer (XRD).
Fig. 1b shows the SEM images of Fe2O3/Al2O3 and Fe2O3/Coal-Ash, in which the Fe2O3/Coal-Ash prepared using 10 wt.% corn starch has loose porous structure and hence larger effective reaction area than other OCs.
Fig. 2b further discussed the activity of inorganic membrane structure OC with corn starch content of 10 wt.%, 20 wt.%, and 30 wt.%, respectively.
The structure of the prepared oxygen carrier was characterized by SEM and XRD.

The ER particles and abrasive particles suspended in silicone oil are polarized in which ER particles strongly attract each other and aggregate into chain like structure along the electric field lines, and the abrasive particles may adhere to the ER chain.
ER fluid-assisted polishing is a new machining method combined the theory of electric field, fluid dynamics and analytical chemistry [5].
Fig1.Mechanism of ERP When the electric is applied, the ER particles are dielectrically polarized and aggregate into chain like structure aligned in the electric field direction, and the abrasives may adhere to the ER chain.
The starch particles surrounding the abrasive particles form a chain-like structure and give bonding strength to the embedded abrasive particles.
Therefore, the ER particle aggregate into chain like structure aligned in the electric field direction.

The chemical phase analysis carried out by X-ray powder diffraction method confirms the major phase of Cu-Zn ferrite structure.
The ternary phase diagram in this ternary oxide system (CuO-ZnO-Fe2O4 ) shows that the phase boundaries are shifted slightly with temperature and adjust the trivalent and divalent metal ions in their respective site to form a spinal structure.
