Thus it is easy to infer that the structure of experimental products is FCC.
As there is a large quantity of dangling bonds and defect structures on the surface of micro/nano-MgO particles, the particles not only can pose nano-film through combine with each other, but also can permeate into metal matrix to produce dispersal layer and permeation layer.

The XRD, SEM and PL spectra have been characterized for the composition, morphology and structure of the as-obtained ZnWO4 and ZnO nano/microstructures.
The feasibility and capability of this hydrothermal approach in this paper is worth exploring for other inorganic systems for the rational designing and high throughput of low-dimensional structures, since it is an efficient and mild solution method with promising advantages over the traditional high-temperature approach.

Introduction Most of the questions regarding the concrete internal structure and its effects on its behavior pertain to the primary hydration product and binding phase of Portland cement paste, the calcium silicate hydrate (C-S-H) gel.
In particular, as new experimental techniques such as nanoindentation provides unprecedented access to micromechanical properties of materials, it becomes possible to indentify the mechanical effects of the elementary chemical components of cement-based materials at the scale where physical chemistry meets mechanics, including the C-S-H gel [4].
After 60 days of hydration, the vitreous structure that enfolded the fly ash begins to break, the active silicon dioxide (SiO2) reacts with Portlandite to form C-S-H gel, the hydrate precipitates on the exposed surface of fly ash.

In recent decades, fractal theory has been successfully applied to the natural sciences and social sciences and other fields, such as engineering, physics, chemistry, biomedical, materials science, astronomy, geography, economics and management, computer graphics, etc. [1] A.
Some well-known fractals · Sierpinski Gasket.Take an equilateral triangle, divide it into 4 equal size equilateral triangle and dig the middle one, divide the three remaining triangles into 4 small and equilateral triangles and dredge the middle one, do this constantly and eventually the resulting pattern constitutes an infinite level of self-similar structure, as shown in Figure 2, called Sierpinski gaskets or arrow pattern [2].
Divide a square into 9 little squares and dig the middle one and dig the middle of one of the remaining eight squares again using the same approach.As Figure 3 shows, so do so, and finally get an infinite level of self-similar structure, known as Sierpinski carpet [2].

In addition, OPEFB is considered polar material due to the existence of hydroxyl groups and C-O-C links in its structure.
High polarity of the main structure makes OPEFB more compatible with polar polymers such as poly acrylamide (PAAm) and poly acrylic acid PAA [9].

EXPERIMETAL PROCESS The chemistries of the steels investigated are listed in Table 1.
At 900oC, only partial recrystallization was observed, particularly, less deformed grains are recrystallized at lower strain rate; moreover, recrystallization was initiated at the deformed austenite grain boundaries, and the recrystallized zone got thickening with the proceeding recrystallization, leading to formation of so called necklace-like structure.

Several applications of GP in modeling of material properties can be found [12].The only difference between GP and GA is that, in GP, the solutions are represented by a tree structure whereas in GA, the solutions are represented by strings in real or binary form.
The structure of ANN consists of three layers: input layer, hidden layer and output layer.

Adjustment of Product Structure As we known, the majority of the world's PET production is for synthetic fibers in nowadays, but the demand for non-fiber PET is increasing, such as PET bottles and engineering grade PET.
The product structure in China PET market will change in the future.

Modification in hygroscopic nature of urea via formation of solid solution, and its particle size and second harmonic generation study RAJASEKHAR BHIMIREDDI and RAMANAND RAI* Department of Chemistry, Centre of Advanced Study, Faculty of Science, Banaras Hindu University, Varanasi-221 005, INDIA * Corresponding author: E-mail: rn_rai@yahoo.co.in, Ph: +91-542-6701597, Fax: +91-542-2368127 Key words: Solid Solution; Urea; Powder XRD; Particle Size; SHG.
The powder X-ray diffraction technique was used to study the structure of binary materials as well as the compositional range of miscibility, of DNB as well as BNA in urea, which forms the solid solution.
The XRD studies indicate that a small amount of BNA/DNB in urea i.e., till their respective monotectic composition has been accommodated in the urea structure without causing any change on its crystallography.

Microscopic image revealed the island structure of these alloys (Fig. 4c).
Ni-Mo alloys obtained by induced codeposition from nickel-molybdenum bath are of molybdenum in nickel (α phase) solid solution characterized by nonocrystalline structure (Fig.5 a) [25] whereas the Ni-Mo+PPy coatings are characterized by decreased peaks coming from Ni-Mo base (Fig. 5b).
