The second line of research was the use of the new particles as tools to explore the microscopic world where physics and chemistry meet.
One is the explorations of the structure of new compounds with unpredicted properties such as the high-temperature superconductor and the "buckyballs".

Introduction The petroleum resources will be dried up in one day[1-3] , coal still be an important position in the energy structure, Yunnan brown coal with rich reserve and shallow buried depth, can be easily exploited and generated many products by low-temperature pyrolysis[4,5], including tar, pyrolysis gas, semi-coke, and ash[6,7].

Improve the Temperature Resistance of Guar Gum by Silanization Jie Zhang*, Gang Chen College of Chemistry and Chemical Engineering, Xi’an Shiyou University, Xi’an, 710065, China Email: zhangjie@xsyu.edu.cn; gangchen@xsyu.edu.cn Keywords: guar gum, temperature resistance, silanization, modification Abstract.
The reaction and the structure of guar gum (GG) solution and silanized guar gum (SGG) were shown in Scheme 1.

However, question arises as to how to attain better integration by modification of the implant surface in its physical chemistry characteristics.

The obtained resin is then placed in the mould and heated under pressure until presenting a solid structure that will be used for the thermo-mechanical characterizations.

However, the characterization of any crystalline defects, especially the dislocation structure in the sapphire is less reported.

The structure of compound 1a was confirmed by 1H NMR(400 MHz, CDCl3): δ 0.83 (m, 3H, -CH3), 0.97-1.16 (m, 12H, -CH2), 1.24 (m, 3H, -CH3), 2.44 (m, 2H, -CH2), 2.65 (m, 2H, -CH2), 7.34 (m, 2H, phenyl-H), 7.59 (d, 1H, J = 3.2 Hz, phenyl-H), 7.71 (s, 1H, thiophene-H), 7.77 (d, 1H, J = 3.8 Hz, phenyl-H), 9.80 (s, 1H, -CHO).

Their structure in the atomic scale, however, has not been well revealed due to lack of experimental tools for them.
