The molecules that, at the same time, contain nitrogen and sulphur in their structures are of particular importance, since these provide an excellent inhibition compared with the compounds that contain only sulphur or nitrogen[2].
Two kinds of Mannich base as an inhibitor were synthesized with Thiosemicarbazide, acetophenone and Cinnamic aldehyde (Mannich baseI) or with Formaldehyde (Mannich baseII).The molecular structure of studied compounds were given as Scheme 1, Scheme 2.
Scheme 1 Structure and synthetic route of Mannich baseI Scheme 2 Structure and synthetic route of Mannich baseII Weight loss studies.

BaTiO3 has single perovskite structure, ABO3, which dielectric properties can be modified through doping.
Tetravalent or pentavalent cations such as Mn+4, Zr+4 and Nb+5can also be used to substitute into Ti site of the perovskite structure [3].

Some components of the electrolyte directly participate in the reaction, changing the structure of the film layer, and thus changing the properties of the film layer.
At present, the electrolyte is mainly composed of an alkali silicate-based electrolyte, and the structure and properties of the film layer are changed by adding various additives.
The additive can effectively change the structure and properties of the oxide film and change the growth rate of the oxide film.

Synthesis new photochromic diarylethenes 1-(2,5-dimethyl thiazole)-2-[4-(2-cyanophenyl)-3-thienyl]} perfluorocyclopentene Weiwei Geng, Shiqiang Cui, Shouzhi Pu* Jiangxi Key Laboratory of Organic Chemistry Jiangxi Science and Technology Normal University Nanchang 330013, P.
The photochromic process of diarylethenes is based on a reversible transformation between the open-ring isomer with a hexatriene structure and the closedring isomer with a cyclohexadiene structure, according to the Woodward–Hoffmann rule [2].
The open-ring isomer is colorless in most cases, while closed-ring isomer shows some color depending on the molecular structures [8].Among the photochromic compounds, diarylethenes are regarded as the best candidates for such devices, because of their advantages such as a high efficiency of photoisomerizations, sufficient thermal stability of both the open and the close forms, a very high resistance to photofatigue, and the ease with which the reaction can be monitored by UV-Vis spectroscopy [4], [9].
The structure of compound 1a was confirmed by 1H NMR spectroscopy. 1H NMR (400 MHz, CDCl3, TMS): δ2.024 (s, 3H, -CH3), 2.067 (s, 3H, -CH3), 2.694 (s, 3H, -CH3), 7.14(s, 1H, thiophene-H), 7.26 (t, 2H, benzene-H), 7.76 (d, 2H, benzene-H).

Most ceramic membranes have a composite structure, consisting of two or more layers.
This was an expected result and related to crystalline structure of clays and occurrence of impurities.
The thickness of gel layer is 5-7 µm and the coatings have homogeneous structure.
Coarse structure of the substrates can be seen clearly.

Preparation of Carbon Micro-spheres from Liquefaction Products of Lignite with NaOH-methanol Zhiping Lei, Lijuan Gao, Hengfu Shui * , Zhicai Wang and Shibiao Ren school of Chemistry & Chemical Engineering, Anhui Key laboratory of Coal Clean Conversion & Utilization, Anhui University of Technology Ma'anshan, Anhui Province, P.
Among the various structure forms of carbon materials, carbon spheres (CSs) have attracted a great deal of attention from many researchers in different areas owing to their excellent physical and chemical properties.
In our preliminary study [12], it was found that lignite can be easily liquefacted with NaOH-methanol and liquefaction products (LP) contained OH group, aromatic structure, carbonyl group and aromatic ether oxygen.
These CMSs are in perfect spherical morphology and some of carbon spheres are inclined to aggregate to form chain-like structure.
The broadening of the ‘‘graphite’’ peaks actually indicates the existence of highly disordered structures in the product [13].

Cellulose has a complex structure with large amount of crystalline regions.
This is mainly due to the inter- and intra-molecule hydrogen bonded supramolecular structure of celluloses, which formed highly crystallized structure to resist the adsorption of enzymes.
Tiny ultrasonic flow produced by ultrasonic field has a certain impulse on the cellulose, which results in the 3-D structure alteration and efficient binding with enzyme.

This indicates that, it has structure water among the nanometer particles in sample.
This illuminates that F-doped makes the structure water among the nanometer particles in sample increase.
It shows that the structure water among the nanometer particles in the sample is disappeared when it is calcinined.
It is considered that, the F-doped changes the crystal lattice structure of the nanometer crystal in the sample.

It is becoming apparent that the control of the film structure is needed to fully exploit the optical, electrical and photoconducting properties of organic materials.
Phospholipids have been used throughout this study due to suitability of their chemical structure to form stable Langmuir monolayers and also their flexibility to organize themselves into molecular architectures [3].
