Recent studies indicate that structure of a-Se having two fold coordination consists of randomly mixed long polymeric Sen chains in which various portions of a chain have ring fragments [7].
As Bi is introduced to host Se-Te alloy, this may create the compositional disorder in the structure of Se-Te alloy which may further leads the change in optical, electrical and thermal properties.

Occurrence structure of China rich in coal but poor in oil, it is a long-term strategy to make full use of coal resources, vigorously develop coal chemical industry, promote the balanced development of economy and society[2].
We induct 10 main kinds of influent factors of the coal chemical industry in Shaanxi province, which are industrial policy, market size, market structure, market growth rates, industrial profit rate, industrial competition strength, technical requirements, capital demand, environmental protection ＆safety requirements and substitute; And we also induct 10 main kinds of influent factors of the coal chemical enterprise competitiveness in Shaanxi, which are development strategy conformity degree, products association degree, natural resource to meet the satisfaction degree, human resources, market share, relative market share, marketing satisfaction, technology maturity, sales contribution rate and investment profit margins[4].

Molecular structure of 2-substituted 4-nitrobenzoic acid.
In this article, we summarize key aspects of solid solution formation and try to identify an approach for prediction of solid solution formation using quantum chemistry calculations.
Several ratios of native and derivative molecules have been investigated: ratios 1:0 (original structure, P21/c), 0:1 (isostructural structure, P21/c) and 3:1 (substituted structure, P1).
If we compare lattice energy of original structure to fully isostructural structure, it gives more detailed information about in which case structure will be more energy efficient (see Table 4).
Total energy changes between original structure and fully isostructural structure Isostructural to ΔE [kJ·mol-1] 2Cl-original structure 2CH3-original structure 2OH-original structure 2Cl4NBA structure - 0.4 – 6.5 2CH34NBA structure 8.9 - – 0.9 2OH4NBA structure 29.5 10.9 - The main thing to observe is that in the case of 2-hydroxy-4-nitrobenozic, the original structure is the most advantageous, and 2OH4NBA molecule can easily replace Cl or CH3 molecules in crystalline lattice.

The electrodes had lamellar structure, which could contribute to the adsorption of gold nanoparticles on electrode surface.
Obviously, GO possesses folding surface and relatively thin layer structure, which is due to the ultrasonic in post-treatment.
The structure of AG becomes flakiness and thicker than that of GO because of the modification of amidogen.
The GO has obvious lamellar structure and fold surface.

Novel CO2 capturer derived from SBA-15 monolith coated with amine Kunkun Han, Yu Zhou, Jingjia Wen, Jianhua Zhu* Key Laboratory of Mesoscopic Chemistry of the Ministry of Education, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210093, China, E-mail: jhzhu@mail.nju.edu.cn Keywords: SBA-15 monolith; 3D net-linked; CO2 adsorption; Environment protection Abstract A new strategy of preparing the efficient CO2 adsorbent without further molding is reported in this article.
However, these in situ coating TEPA composites did not have the well ordered mesoporous structure; besides, it is unknown whether the monolith coated with TEPA in post-modification can exhibit such high adsorptive capability.
Results and Discussion Structure characterization Figure 1A unveils the macroscopic appearance of SM sample, while SBA-15 presents the powdery appearance.
Also, they yielded a narrow pore-size distribution with a mean value of around 9.0 nm from the adsorption progress, mirroring the almost same textual structure of SM to SBA-15 (Fig. 3A, Table 1).
However, this composite is still less active in adsorption of CO2 than our previously reported in situ coated mesoporous composite (170 mg g-1, [6]), because of the different type of host pore structure and different coating procedure of TEPA guest that strongly affect the final function of adsorbent.

Simultaneously, the characteristic peak at approximately 38.3o, 44.4o, 64.5o and 77.6o are correspond to the Ag structure, which is due to the Ag nanoparticles are formed form Ag+ ions.
The GO is a thin sheet with a smooth surface (Fig.3a), the Ag nanoparticles homogeneous dispersion in the RGO sheets (Fig.3b, 3c, 3d), and this may be attributed to PVP adsorption on the surface of GO by strong Π-Π interaction due to the pyrrolidone of PVP close to the structure of GO [17], the PVP can protect the Ag nanoparticles via N and O coordinate with silver and form the protection layer [23].
