Aluminum nitrate nonahydrate (Al(NO3)3.9H2O, 99.999%) powder and ethanol (purity 99.7%) were used as starting material and solvent, respectively.
The Al(NO3)3.9H2O powder was dissolved in ethanol through ultrasonic agitation.

Calcium phosphate bioceramics, including beta-tricalcium phosphate (β-TCP), hydroxyapatite (HA) et al. are the most attractive synthetic bone substitutes because of their excellent osteocondutivity[2-5].

Yang et al. [5] stated that most of the polyurethane/waterglass composite grouting materials are fragile and stiff, which cannot meet all of the requirements in many practical applications.
Prolongo et al. [8] stated that epoxy resins cured with aromatic amines generally present good thermal and chemical resistance, while the benefits of anhydride hardeners are their low contraction, viscosity and excellent thermal resistance.

This phenomenon is in agreement with the results reported by Yu Wang et al. [8] with anodic oxidation process in the glycerol electrolyte at 30 V, 2 h, pH of 6 and 40 oC at 20 and 40 wt% water content.
A similar result is also presented by Muhamed et al. [5].

In contrast to the EDX spectra of bare-Mn-doped ZnO, the EDX spectra of montmorillonite-modified Mn-doped ZnO obviously revealed Si and Al peaks, which are due to the incorporation of montmorillonite in the sample.

As a matter of fact, at the beginning of the seventies, a team of French researchers directed by Leray et al, [7], noticed the existence of a discretization of the angles which formed the helicoids vortices (resulting from the combination of the rectilinear vortices and a flow of translation) with their axis.
Based upon this microscale display; the same privileged angles were found by Leray et al. [7] to also exist at a macroscopic scale in the case of Helium II supra fluid flow.

Numerous simulations done by Bouffioux et al. [8, 9, 10] confirms that the line test FE predictions are very sensitive to the choice of the finite element, the mesh density, the isotropic and kinematic hardening law and the identification method of the material set of parameters.
The parameters of these laws were identified by Henrard et al. [12] using several combinations of a tensile test, shear tests and an inverse modeling approach taking into account a test similar to the incremental forming process.

Hayat et al [15] analyzed the boundary layer flow of Carreau fluid over a convectively heated stretching sheet.

In this study, a value of T2 equal to twice the first mode period was chosen, because Cordova et al. [5] identify it as adequate, and Bojórquez et al. [22] confirm this for nonlinear SDOF systems and considering different performance parameters.
