Sathishkumar et al. [7] investigated the structural and dielectric studies of Co(0.5-x)NixZn0.5Fe2O4 (x = 0 to 0.3) prepared by co-precipitation technique.
Tang et al. [9] prepared Co1-xNixFe2O4 (0 ≤ x ≤ 1) nanoparticles (NPs) and found that the saturation magnetization (Ms) decreased linearly with increase in Ni2+ contents.
For instance, Harish et al. [14] investigated the photo-catalytic property of neodymium-substituted nickel ferrite nanoparticles NiFe2−xNdxO4 (where x = 0.0, 1.0, 1.5, 2.0).
Similar result was reported by Chavan et al. [21].

The study by Barbosa et al [12], they used ferrite Ni0,5Zn0,5Fe2O4 methyl esterification reaction in soybean oil.
The work of Dantas et al [13], they made a comparative study of the catalytic nanoferrites activity Ni0.4Cu0.1Zn0.5Fe2O4 and Ni0.1Cu0.4Zn0.5Fe2O4 as catalysts in the methyl transesterification reaction of soybean oil.
These two events were also reported by Wu et al [22] when they studied the fuel effect on chemistry and electromagnetic properties of Ni-Zn ferrite doped SiO2.
Similar results of the reference (DBET/tc) were reported by Costa et al [25], when they studied the synthesis and characterization of Ni-Zn ferrite doped with copper.

In this way, Malzbender et al [20] obtained an average interfacial toughness of 0.18
MPam0.5 for their hybrid coatings which falls into the range determined previously based on
analysis by He et al [21].
Another adhesion model based on equilibrium theory and the solution for the deflection of a centrally loaded disc was proposed to deal with the same phenomena by Hainsworth et al. [37].
Marshall et al [43] proposed a model to relate the toughness of brittle bulk materials to the depth where lateral cracks occur and the crack driving force Pr due to the residual stress during unloading.
Here the hardness and elastic modulus are composite parameters resulting from the contribution of coating and substrate which can be estimated based on an energy-based model developed by Bull et al. [44-46].

Recently, Zhu et al. [8] found a new high-pressure phase of Mg2Si with a monoclinic structure at pressures of 11.1–37 GPa.
At the postprocessing stage, the symmetry of various structures was identified using the ISOTROPY package of Stokes et al. [17], implemented by USPEX.
These results confirm other high-pressure structures besides P63/mmc and Pnma can be involved, explaining the observation of a new monoclinic structure reported by Zhu et al. [8].
The lattice constant for the antifluorite structure at P=0 coincides with the theoretical results of Hao et al. [19] and agrees with the experimental data of 6.35 Å [19, 21] and 6.34 Å [22].
According to the early proposals of Dyuzheva at el. [23, 24], based on X-ray data analysis there are possible polymorphic transformations of the Ni2In structural type (by analogy with the Mg2Sn polymorphic phase transition [25]) due to a different linking of the identical coordination polyhedra.

In addition the thermal conductivity of Al2O3 is below that of pure aluminum.
So for these experiments the amount of Al 4047 A was normalized with respect to the welding speed.
