Introduction Tremendous advances have been made during the last two decades in our understanding of the chemistry, structure, electrochemistry, electrical and optical properties, processing routes and applications of conducting polymers of which polyanilines is the most widely exploited [1-16].
Conducting polymers are characterised by a conjugated structure of alternating single and double bonds.

Ethylene glycol dimethacrylate (EGDMA), di-n-octyl phthalate (DOP), high molecular weight polyvinyl chloride (PVC) and theophylline were purchased from Aladdin Chemistry Co., Ltd.
It can be seen that the surface of the MIP exhibits a more porous and rough structure than NIP.
The regular structure of the non-imprinted polymer is due to the fact that no specific binding sites are created for the polymer.
The cavities in the MIP are probably caused by the structure of the target caffeine molecule.

However, dendrite–like aragonite and flower–like vaterite [16], rod–shape aragonite, hexagon vaterite and tube–shape vaterite formed by the rolling up of a pseudolayed structure [17], rod–like aragonite grains with high and low aspect ratios [13] have been obtained at 90°C or above temperature.
What should be note that some rod–like particles look more like the rolling structure of lamellar grains (arrowed in Fig. 3b and e), similar to Chen et al.’s research [17].

These are dissimilar in term of structure and morphology.
The absorption bands at 3200-3800 cm-1and 700-1800 cm-1 correspond respectively to –OH stretching and –OH bending of water molecules in calcium sulfate structure.
Role of ethylene glycol on the transformations of DH to α-HH The phase transformation of DH to α-HH has been investigated using Eq 1, The theory of crystal structure formation of α-HH are dissolution-recrystallization [14] as shown in Eq 2 and Eq 3.

It indicates the ultra-fine nature, cubic phase structure and small crystallite size of the particles.
However, the crystalline structure of the synthesized SiO2 coated SPION in figure 5a is similar to that in figure 5b.

Low-temperature Pyrolysis Characteristics of Inner Mongolia Lignite Zhenxin ZHAO1， Buwei MA1， Shuquan ZHU2， Haijin ZHENG1 1 Department of Chemistry and Chemical Engineering， Henan University of Urban Construction， Pingdingshan， Henan，China 2 School of Chemistry & Environmental Engineering， China University of Mining & Technology (Beijing)， Beijing， China Email: zzx@hncj.edu.cn Key words: lignite; low-temperature pyrolysis; semi-coke; gas product Abstract: The utilization of high moisture, high volatile low rank coals such as lignite is gaining importance day by day to meet the growing demands of coal for the energy sectors.
So it is of great significance to the development of new technology for lignite conversion to analyze the composition and structure of the lignite before and after modification, which conducives to the rational utilization of the lignite resources[3].
Because the unsaturated structures of lignite such as alicyclic and bis ethylenically are more, the condensation cross linking reactions are prone to produce when the lignite is heated, and the char yield is significantly reduced.
The macromolecular structure of the coal exhibits a "thermal inertia".

XRD, FESEM and H2-TPR were applied to characteristic crystalline phase structure, morphology, thermal-stability of LCO samples.
Many synthesis methods were commonly used to prepare perovskite-structure compound oxide, such as high temperature solid phase combustion, sol-gel [8-10], co-precipitation [4, 11, 12] et al.
The possible reason for the above phenomenon is that methyl orange and gold orange II have different surface chemical structures (Fig. 7).

The general structure of molecules of physiologically active substances should correspond to the structure of specific molecules of cells.
For this reason, it is very important to buy amines with different structures and functional substitutions.
So, with this method, no solvent is used in the synthesis process, a high-yield product is obtained based on an efficient and safe technology, and the principles of "green chemistry" are ensured.
For this reason, the acquisition of amines with different structures and functional substitutions is of certain importance.

Fig. 2(a) is a SEM image at low-magnification, and indicates that many pimple-like structures grown on the surface of the nickel grain.
The morphological features of the pimple-like structures were clearly displayed by a high magnification SEM image (Fig. 2(b)).
It clearly shows that the morphology of the pimple-like structure is actually nanorod.
The measured lattice spacing is 0.27 nm, corresponding well to the (200) lattice spacing of the cubic Si structure.

There were a few changes in the structure of ZnO@PDA or ZnO-Ag @PDA.
The metal oxide@PDA with a melanin-like structure can act as a photocatalyst, light absorber, electron transfer receptor, and adhesive interface under the light.
The structure of the ZnO nanoparticles almost had no change after being coated by DA.
The reduction of Eg may be due to the absorption of light by the melanin-like structure of the PDA itself, which affected the diffuse reflectance spectrum.
