The slopes of the load relative to the displacement are almost the same for three tests of naylon-6 nanofiber, but, the extent of elongation after the maximum load differed among the samples, which can be attributed to the non-uniformity of the fiber structure.

However, the properties of boried parts depend to a significant degree upon the structure of the boried layer.
Moreover Na２B４O７ + SiC medium have such a high viscosity that it suppresses the penetration of boron 3.2 Effect of steels chemistry Figure 3 shows the hardness distribution at the cross section of S35C, SCM435 and SUS420 steels with varying Cr contents boried at 1258K for 18ks in SiC agents by induction heating.

The structure of compound 1a was confirmed by 1H NMR(400 MHz, CDCl3): δ 1.89 (s, 3H, -CH3), 4.68 (s, 2H, -CH2-), 6.94 (s, 1H, thiophene-H), 7.56 (t, 1H, J=7.6Hz, phenyl-H), 7.65 (s, 2H, phenyl-H), 7.73 (t, 1H, J=8.0Hz, phenyl-H).

Research on the Strength of Green Hydroxyapatite Coating Obtained by Electrophoretic Deposition Lin Gao College of Chemistry and Environmental Engineering,Yangtze University, Jingzhou, China carbongl@yahoo.com.cn Keywords: Hydroxyapatite, Green coating strength, Electrophoretic deposition, Ripening time, Dispersion medium Abstract.
The common problem existed in our laboratory was the loose structure of green coating when ethanol or n-butanol was used as the dispersion medium.

Introduction MATLAB is the mathematical software launched by American MathWorks company in the 1980s, as can complete all kinds of data processing, visualization and easy to use and powerful mathematical tool, has been widely used in mathematics, physics, chemistry, engineering, finance and other complex computational domain.
It is based on the wavelet multi-scale edge detection, using the potential field anomaly information, spatial derivative and a variety of geological body has specific structure index to determine the anomaly field source location.

Encouraged by the development of green chemistry, the utilization of renewable natural materials has received considerable attention.
Polysaccharides and other biomacromolecules have already been utilized as templates to prepare porous metal oxide structures [6].

(1) where c is methyl orange solution concentration at time t, in mg / L; and c0 is the initial concentration of methyl orange solution, in mg / L. 2.3 Characterization X-Ray diffraction (XRD) patterns were obtained on a D2PHASER X-ray diffractometer (Bruker, Germany) using Cu Ka irradiation at a scan rate (2θ) of 0.05°s-1 and were used to determine the phase structures of the obtained samples and their crystallite size.
