Surfactants with special molecule structures and properties play a key role in reverse micelle.
The relationship between the P value of surfactants and structure of the reverse micelle From the obtained results, it was confirmed that when P was less than 1.35, layer structure reverse micelle formed, which made CaSO4 present nanometer flakes; when P ranged from about 1.4 to 2.5, clavate structure reverse micelle was formed, which made CaSO4 present nanometer rods; when P was greater than 3.4, spherical structure reverse micelle was formed, which made CaSO4 present nanometer spheres.
(2) When P was less than 1.35, layer structure reverse micelle was formed, but when P ranged from about 1.4 to 2.5 or greater than 3.4, clavate structure or spherical structure reverse micelle was formed respectively

Silicone usually refers to linear polymers with the following structure: Fig. 1 silicone structure The R groups along the chain where = Methyl or PDMS can be substituted by many other groups.
Silicone polymers do not have carbon as part of the backbone structure.
Although the silicon is in the same group as carbon in the periodic table, it has quite different chemistry.
Silicone polymers have an alternating -Si-O- type structure.
The most prominent factors affecting these structures are the environment, pollution, and tourism.

Selected structure analysis results including XRD and TEM/EDX as well as elevated temperature tensile testing are presented.
Consequently, the 356 and 319 chemistries can not maintain their properties at highly stressed areas and temperatures reaching up to 250o C [1-4].
To meet such requirements proper development of alloy chemistry and heat treatment processing is needed [5].
Experimental Procedures Two primary Al-Si-Cu base alloys were selected from about 30 chemistries studied so far.
This was done to determine the effects of alloy chemistry and processing parameters on structure development.

Raman spectroscopy was used for structure analysis of CNFs synthesized by catalytic combustion technique.
Figure 4 shows a strong D peak and a weak G peak, indicating relatively small size graphite clusters within the CNF structure.
Raman spectrum of typical sample produced by using 1mol/l ferric chloride as the catalyst precursor over copper plate. higher than the D band, indicating relatively large size graphite clusters within the CNF structure.

The most common method of synthesis of nano-sized powders is by the use of a "wet chemistry" process.
The reverse microemulsion system exhibits a dynamic structure of nanosized aqueous droplets which are in constant formation, breakdown, and coalescence.
The diffractograms of the two samples correspond to the barium hexaferrite structure, except for the additional minor peaks corresponding to haematite in the case of mE-I.
The particles in sample mE-I were predominantly of a platelet-like structure with an irregular shape and an average size of 180 nm.
It should be pointed out that the magnetic parameters of sample mE-IІ are comparable to those of powders produced by other "wet chemistry" techniques.

Indium selenide (In2Se3) is an important narrow band gap III-V semiconducting material with a layered crystal structure.
Among them, hydrothermal or solvethermal method is regarded as a very effective and potential soft-chemistry route to tune the architectures of metal selenide.
Weon-kyu Koh et al[7] studied the role of different Se precursors for PbSe nanorod synthesis, focusing on phosphine chemistry to understand precursor decomposition (Figure 1c).
Prospects Metal selenide nanostructures have novel properties and functions corresponding to their unique structures.

This is because the different interaction between crude oil components (asphaltenes ,resins ,aromatics and saturated hydrocarbons)and rock and different displacement solution of different displacement ability make the content of asphaltenes and resins in produced crude oil different.The interaction between unsaturated hydrocarbon polarity and rock is mainly VDW(lesser),adsorption viscosity on rock surface is small,so it is easy to be out;aromatic hydrocarbon with weak polarity and have benzene ring structure so that the interaction among the rock expect VDW is the coordination bond with the bigger interaction formed byπbond and the cation on the rock surface ,the interaction between the bigger coordinate and the rock is bigger than saturated hydrocarbons,therefore,the adsorption viscosity on the rock surface is bigger than saturated hydrocarbons,make it hard displacement compared with the saturated hydrocarbons;Asphaltenes and resins have polycyclic aromatic hydrocarbons.The interaction
increase of asphaltenes content,more and more asphaltenes gathered on the oil-water interface,the strength of the film increased gradually,the emulsion stability increased,but when concentration of asphaltenes increased to its critical concentration,because of the special structure of asphaltenes[4]，it is easy to form hydrogen bond and aromatic sheet easy accumulation form a larger micelle aggregates between molecule,causing the oil - water interface asphaltenes concentration decreased and the emulsion stability decreased.For the resins,with the increase of resins content,dehydration rate gradually decreased.Because it is difficult for resins to form micellar aggregates,with the development of oil - water interface resins concentration increased,the strength of the film increased,stability gradually increased.
