The structures and properties of Nylon 6/MgAl-LDH nanocomposites were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA).
Introduction Polymer/clay nanocomposites (PCNs) are of important interest because the structure and chemistry of clay imparts excellent thermal and mechanical properties[1,2].
The obvious lamellar structure of MgAl-LDH homemaded can been found.
TEM had been used to directly observe the structure of the nanocomposites, with emphasis on the MgAl-LDH dispersion in nylon 6 matrix.
The layered structure and the low content of MgAl-LDH in nylon 6/MgAl-LDH nanocomposites are probably the main reasons for the comparable thermal stability of neat nylon 6 and its nanocomposites under nitrogen environment.

All as-synthesized alumina with well-defined pore structures have large surface area.
However, the hierarchical microsphere structures assembled from nanoparticles with mesoporous structure have not been seen in the literature.

Secondly, the question of hydration of two-calcium slime in this case is limited only to the consideration of the formation of CSHI, that is, the varieties of the structure of the dicalcium silicate are not taken into account.
The peculiarities of silica transition into alumina solutions during the leaching of sinters of various types are primarily related to the structure of two-calcium silicate.
The phenomenon of oversaturation of aluminate-silicate solutions in this case can be explained by their structure of aluminum (III) silicon hydroxoforms (IV) in these solutions.
This is directly related to the structure of the silicon-containing reagent CSHI, which is a direct source of silica intake into alumina solutions.

Then, the prepared solutions had been used to prepare a conductive polymer with nanofibrous structure using electrospinning technique.
Finally a comparison was made between the pure PMMA and PMMA+ iodine additives sheets in the electrical conductivity and structure.
The chemical structure of the fibers was examined with (EDX) spectroscopy attached with SEM device.
The structure of the electrospun fibers from pure PMMA solution can be studied using the SEM image revealed in Fig. 6 (a).

The particles of kaolin are extremely small and it obvious shows a layer structure.
Part of the surface of the composite presents polymerization and no fixed form, and part of it shows obvious cracks, loosen surface, uneven wrinkles and the structure of layer.
It can be explained by that kaolin influence the internal structure of the material more than neutralization degree does.
Kaolin, a kind of clay minerals, has a structure of dioctahedron, which is formed by silicon-oxygen tetrahedron and aluminium-oxygen octahedron at the ratio of 1:1.
But these are just assumptions based on some researches, and the real mechanism needs further study of its components, structure and other factors.

Four alloys have been investigated, two fully recrystallized, AA6060 and AA7030, and two with fibrous grain structure, AA6082 and AA7003.
These cover both industrial interesting alloy systems and different grain structures (cf.

The optical microscopy confirmed the assumed grain structure of the as-extruded material.
Alloy 6060 is characterized by a fairly equiaxed grain structure with an average grain size of 110 mµ , while 6082 shows a fibrous microstructure with a thin recrystallized surface layer approximately 100-150 mµ thick.

Because of the relationship between viscosity and structure of molten slags, studying viscosity is also an effective means to come to realize the structure of molten slags.
Ingram [2] first formulated the concept of optical basicity, when studying the structure of silicate glasses.
All of these models were developed through correlating the activation energy of viscous flow (E) and optical basicity (Λ) to calculate viscosity which is closely related with the slag structure.

Shokrieh and Rafiee [13] and Shodja and Delfani [14] presented analytical formulations to predict the elastic moduli of graphene sheets and CNTs using a linkage between lattice molecular structure and equivalent discrete frame structure.
Mathematical Formulation 2.1 Molecular Mechanics Effect To establish a linkage between the microscopic chemistry and the macroscopic mechanics, covalent bonds between carbon atoms is represented by a force filed as a function of bond lengths and bond angles.
This phenomenon is consistent with the shell structure theories, Srubshchik [72].
