Although hydroxyapatite is widely used as an osteoconductive biomaterial, carbonate apatite is more similar to the inorganic component of teeth and bone, and can be used as bioresorbable materials for filling bone defects [6].
Consequently, n-CAPs play a role in the synthesis of various materials.

For crystal A, 0.2 % wt vanadium was added to the source material.
To investigate the compensation of acceptors as well, crystal B was grown co-doped by adding 0.2 % wt vanadium and 8 ppm wt boron to the source material.
Journal Title and Volume Number (to be inserted by the publisher) 3 (iv) The results are consistent for any V 4+ and V 3+ absorption peak, although for different peaks minor deviations in the ratio of peak heights exist (see Fig. 2).

It can put a series of irregular parts in given materials, find out the optimal nesting of parts, have a highest material utilization ratio, so as to save material and improve the economic efficiency.

While magnesium alloys would normally not be candidates for bearings or gears, there are situations in which their surfaces could come into contact with other materials so as to make their friction and wear behaviors of interest.

In the past few years, the theory of the chaotic mixing has been mature and widely used in the real engineering, especially in the mixing of high viscosity fluid such as polymer blending, and in the processing of delicate shear-sensitive materials [2-4].
In the language of dynamical system, the results of geometric and statistical properties imply that in the chaotic zones material is stretched along one dimensional unstable manifold with the self-similar structure related to topological entropy rather than Lyapunov exponent [3, 4].
