Ni-Zn ferrite has a cubic spinel type crystal structure whose general formula is AB2O4, where A represents a divalent cation in tetrahedral interstices and B a trivalent cation in octahedral interstices.
The synthesis technique by combustion reaction is based on the thermodynamic concepts of the chemistry of propellants and explosives, involving redox reaction mixtures that contain the metal ions of interest, such as oxidizing reagents, and a fuel, usually urea [CO (NH2)2] or glycine (C2H5NO2) as a reducing agent [11, 14].
To carry out the combustion reaction of the starting mixture, the ratio of each reagent was calculated according to the reactive valences of the elements established stoichiometrically based on the concepts of the chemistry of propellants and explosives [15].
The structures of the samples were analyzed by X-ray diffraction (SHIMADZU XRD 6000 X-ray diffractometer), under CuKa radiation.

The specific binding of antigen and antibody is based on both the structure and spatial complementarity and compatibility, including the charge gravity, the gravity of the van der Waals, hydrogen bonding force and hydrophobic interaction.
This feature is determined by the primary structure of antigen and antibody.

Among the AIE luminogens, tetraphenylethene (TPE) possesses a simple chemical structure [7] but shows an outstanding AIE effect.
We propose that joining thiophene moiety and TPE structure may bring about new functionalities that combine the unique properties of the two excellent materials.

In order to resolve the delamination problem, the conducting polymer should be interpenetrating network-like structure with the SPE matrix.
So most of the conductive polymer was formed at the surface, however some was formed in the midst of SPE matrix for providing good interlocking structure.

The mesh adopted is a fully structured grid consisting of 4.1 millions of nodes, with a minimum orthogonal quality of 0.327 generated with ANSYS® Icem CFD Hexa.
In order to assure a complete structured grid, extensive use of non conformal interfaces has been adopted between swirlers and the chamber core.
The interaction between turbulence and combustion was evaluated using the combined Finite Rate Chemistry/Eddy Dissipation model [4].
The bsl RSM RANS turbulence model and the combined Finite Rate Chemistry / Eddy Dissipation combustion model were used in the numerical computations.
