The strengthening
component in pearlite is cementite with a chemistry of Fe3C, whereas in the Cu based composites
discussed in this paper, the strengthening component can have either fcc structure or body-centered
cubic (bcc) structure and the chemistry of the strengthening component is much simpler than
cementite.
The non-equilibrium structure offers, therefore, an enormous variety of features far away from the ideal lamellar structure.
Engineering Mechanical Properties by Optimization of Chemistry.
The Cu-Ag composites usually use the chemistry between 1-25 wt% Ag in Cu.
Among these chemistries, proeutectic Cu rich phase forms before the eutectic product.

Abstract.
The structures and properties of the composite were characterized by FT-IR, TGA, X-ray diffraction spectroscopy, and four–probe machine.
Introduction Montmorillonite (MMT) clay with a 2:1 mica-like layered structure, an important class of lamellar inorganic compound whose interlayer spacing can be modified by cation exchange, has been widely used for preparing organic–inorganic nanocomposites[1,2].
In this communication, from the point of the physics and chemistry design, PPy/MMT nanocomposites was selected for further investigation.
This suggests that PPy molecular chain has inserted into the MMT layers space and the lattice structure has destroyed.

Keywords: Phthalocyanine; Third-order nonlinear optical property; Z-scan; Optical limiting property.
In order to search for the applicable materials, considerable effort has been invested into the research of relationship between the molecular structure and the third-order optical nonlinearities.
But, a definite conclusion of the relationship between the electronic structure of the central metal atom and the third order optical nonlinearities has not been reached in the present study.
The molecular structures of the Pc samples are displayed in figure1, and the linear spectra of them in DMSO solution are also presented in figure 2.
Above results show that the optical nonlinear absorption and refraction effects of Pc samples have an intimate connection with the electronic structure of the central metal atom.

The results show that SBA-15, MCM-41 with two-dimensional hexagonal structure has a better adsorption effect on chloride ion than KIT-6 With cubic core structure, and MCM-41 with larger specific surface area and smaller pore size has better adsorption effect on chloride ion than on SBA-15.
MCM-41 and SBA-15 have good dispersibility in aqueous solution, and both belong to a two-dimensional hexagonal structure, and the structure is simple, which is favorable for chloride ion adsorption.

Mesoporous Al2O3 was synthesized from aluminum nitrate using different surfactants as structure-directing agents.
For the micelle can change the interfacial energy and interfacial properties, these help forming homogeneous distributed mesoporous structure, and lead to the improvement of pore structure and adsorption capacity of Al2O3. 3.3.
It illustrates that surfactant can help obtaining homogeneous mesoporous structure of Al2O3[7,8].
The prepared Al2O3 has mesoporous structure with the pore diameter mainly centered at 1-4nm.

A supramolecular assembly structured gel is formed by associating polymer side chain with wormlike micelle of surfactant.
The viscoelastic properties and gel structure were characterized by dynamic rheometer and cryo-TEM.
We hereby study a new class of surfactant with wormlike micelle structure in combination of associating polymer.
It can be seen that threadlike structure with about 10nm in diameter and >1 mm in length exists.
