The alloy chemistry and morphology of the solid particles need also to be controlled in order to achieve a solidified alloy structure that will result in optimal mechanical properties.

The number of research projects aiming to develop the constitutive equation from the exact laws of physics and chemistry has in the recent past been steadily increasing [11].
The structure of the mathematical model's solutions (a=0.3, b=0.012, n=0.2, ΦT =1, 1=tδ ).

Synthesis and Swelling Behaviors of Poly(sodium acrylate)/Hydroxyapatite Superabsorbent Nanocomposites Jinlei Wang1, 2, a , Yian Zheng1, b and Aiqin Wang1, c * 1 Center of Eco-material and Green Chemistry, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, Lanzhou, 730000, P.R.
As discussed above, the incorporation of HP can improve the surface structure of the resulting superabsorbent nanocomposites (Fig.2b), and therefore facilitate the permeation of water into the polymeric network, resulting in a higher swelling rate.

Research on the behavior of materials subjected to multiaxial loadings are closely related to areas such as physics, chemistry, mathematics and computer science and seeks to generate ideas, methods and concepts to provide precise answers to industrial and scientific problems and challenges.

The combustion reaction synthesis was more efficient in magnetic nanoferrites production and these materials with spinel type structure are promising for esterification reaction of soybean oil to biodiesel production, as there were active in that conversions reached 57%.

Fuzzy mathematics applied to heavy metal pollution in the marine environment, the calculation of water quality assessment - A Case Study of Lianyungang Marine Wenbin Chen 1,a 1 Department of Chemical E ngineering, Huaihai Institute of Technology, Lianyungang,Jiangsu 222005, China achenwenbin111@sohu.com Author introduction：Wenbing Chen (1970－) male, vice professor, master, majors in research of chemistry.
Fuzzy Evaluation Method of principle, Structure and Calculation Method Fuzzy set concept is the characteristic function of fuzzy mathematics in intermediate state, and use membership function represents fuzzy set.

This method depends upon water diffusionn through the polymer matrix for dissolution of the fluoride compound withh subsequent outward migration of the fluoride, but which may over time result in voids in the matrix and thus weakening of the material structure.
Thus, the post- polymerisation component of the setting reaction is acid-base in nature with some features in com- mon with the glass ionomer cement chemistry, most notably the release of fluoride.
