Nanostructures have great demand in areas such as chemistry, catalysis, electronics, energy, and medical applications.
Nano crystalline silver structures have found tremendous applications in high sensitivity bio-molecular detection and diagnostics, catalysis, antimicrobials, therapeutics, and micro-electronics. [2-7]However, there is still need for establishing cost effective commercially viable as well environmentally clean synthesis route to prepare silver nano-particles.[ 8] Several approaches are available for synthesis of silver nano-particles such as, solution reduction process, photochemical and chemical reactions for reverse micelles, ionic and thermal decomposition of silver compounds, radiation assisted, electrochemical, sonochemical, microwave assisted process and recent process via green chemistry route.
The green wet chemistry approach for the synthesis of silver nano-particles is having many advantages such as, ease with which the process can be scaled up and economic viability, etc.

The structure of synthesized elastomers was studied by Fourier transform infrared spectroscopy (FTIR).
This type of material has a distinctly segmented structure, which is the key to its behavior as strong physical rubbery network.
Many researchers have investigated the microdomain structure of segmented polyurethanes and isocyanate conversion using FTIR method [5, 6].
Results and Discussion SEM micrograph of polyurethane with 1 wt. % of bentonite (Fig. 1c, e.g.) shows the phase separated structure of prepared nanocomposites.

The XRD analysis shows the presence of ZnO thin films with a hexagonal wurtzite structure.
When the deposition cycle increases to 500 and 800 cycles, however, crystalline ZnO structure can be obtained.
XRD analysis confirmed that only ZnO was present with wutrtize crystal structure.

Intercalation process occurs by the topotactic incorporation of mobile guest molecules (may be neutral, anhydrous or solvated ions) into the accessible interlayer space of the layered host structure [12].
Based on the results obtained, it can be confirmed and concluded that the molar mass of amines has a major effect on structure and surface properties of bentonite clay.

At pH 2 and 6 the MnO2 deposited as the superfine nano-rod structure.
After the deposition of MnO2 the tubular structure of the CNTs becomes thicker with an increment in the tubular diameter size to approximately 50-80 nm.
The surface roughness of the tubular structure of CNTs with the present of MnO2 deposition has increases with decrease of the pH.
It can be seen that CNT-MnO2 pH 8 is coral-like structure in Fig. 2(a).

It is the intention to provide a basis for the structure design and improve combustion efficiency of the cement precalciner.
Geometrical Model and Generating Grid The entity structure of the precalciner is given in Fig.1.
To simulation numerically, the structure need to be meshed by Gambit software, as shown in Fig. 3.
The main challenges in modeling turbulent combustion are handling the mean rate of reaction and adequate representation of the chemistry in the model.
The structure of precalciner is well designed and can meet the need of manufacture.
