For the quantum chemistry calculation, energy barrier and kinetic energy for a carbon atom intrudes into a model cluster has been calculated with an ab-initio computational chemistry software package, Gaussian.
In addition, since the periodicity of the crystal structure on the steel surface is lost by drilling, the cluster model is a valid model for the drilled surface.
Quantum chemistry calculation software Gaussian was used for the calculations.
The hypotheses (A) and (B) were examined by the quantum chemistry calculation and experimental.
For the quantum chemistry calculation, five model clusters with different atomic compositions were prepared, each energy change ΔE and Eb were calculated with an ab-initio computational chemistry software package, Gaussian.

The fourier transform infrared spectrum(FTIR) and 1H nuclear magnetic resonance spectroscopy (1HNMR) were used to confirm its structure and composition.
In this work, we designed and synthesized an optically active amphiphilic graft copolymer bearing quinine pendants poly[3,3-bis(triazolyl-L-quinine) methyl oxetane]-g-poly(ethylene oxide) (PBTQMO-g-MPEO) using copolymer transformation and ‘‘click’’ chemistry (Scheme 1).
The gel permeation chromatography (GPC), 1HNMR spectra and fourier transform infrared spectrum(FTIR) were carried out to confirm its structure and composition.
Fig. 3 FTIR spectra of PBTQMO-g-MPEO Conclusions In summary, ‘‘click’’ chemistry was adopted to immobilize of 10,11-didehydro quinine onto azido-modified graft amphiphilic copolymer, which provided a convenient way to generate various optically active amphiphilic graft copolymers bearing quinine pendants.

The molecular structures of each isomer were evaluated on the basis of single point energy with zero point vibration correction.
And the stability of geometric configuration was carried on frequency analysis and determined by the related vibration frequency data. 2 Results and Discussions In the chain structure of polybutadiene, vinyl in 1, 4 polybutadiene structure are included in the chain, and in 1, 2 polybutadiene structure are include inside chain.

In this paper, LaMnO3/α-Al2O3 magnetic nanocomposites were synthesized through using a soft-chemistry route.
The synthesis strategy in this work is based on a soft-chemistry process using a polyacrylamide gel route in which citric acid is employed as the chelating agent.
(iiii) The organics is decomposed during calcinations, and the frame-structure α-Al2O3 / LaMnO3 composites forms.
Other LaMnO3 nanoparticles are implanted in the porous α-Al2O3 inside to form complex structure.
XRD analysis indicated that the as-synthesized samples are rhombohedral α-Al2O3 and perovskite structure LaMnO3, suggesting that LaMnO3 /α-Al2O3 magnetic nanocomposites can be prepared by a soft-chemistry process and sintering at about 600 ˚C.

Monoclinic Li3V2 (PO4)3/C cathode material has been synthesized by soft chemistry route and the electrochemical performance of this material was investigated.
The structure of the particles was characterized by X-ray diffraction (XRD).
Soft chemistry routes could provide intimate mixing of the reactants in molecular level and hence the product is of better homogeneity.
The structure of the product was characterized by X-ray diffraction analysis (XRD, Rigaku Ultimate IV) with Cu Kα radiation.
All diffraction peaks can be indexed to a monoclinic structure with space group P21/n.

Structure of the thiol-compounds was characterized by FT-IR, 1H-NMR.
Structure of the COMP was recorded with Nuclear Magnetic Resonance Spectrometer (AVANCE III 400, Brooke Company in Switzerland) and FT-IR (Spectrum 2000, Perkin Elmer).
Because the prepolymer had a relative neat structure contained polor ester, urethane and hydrogen bondings; which had greater cohesion and higher viscosity.
Structure of the COMP was characterized by FT-IR, 1H-NMR.
