Introduction The application of nanoscale materials and structures is an emerging area of nanoscience and nanotechnology.
The observation of silver nanoparticles by TEM showed that wire-like structures were synthesised at acidic pH (Fig. 2A).
Dendritic structures were obtained by agglomeration (Fig. 3A) and the platinum nature was evidenced by electron dispersive spectroscopy (Fig. 3B).

Modelling the evolution in microchemistry and its effects on the softening behavior of cold rolled AlFeMnSi-alloys during annealing Emmanuel Hersent1,a, Ke Huang1,b, Jesper Friis2,c, and Knut Marthinsen1,d 1Department of Materials Science and Engineering, NTNU, NO-7491, Trondheim, Norway 2SINTEF Materials and Chemistry, NO-7465, Trondheim, Norway aemmanuel.hersent@material.ntnu.no, bke.huang@ntnu.no, cjesper.friis@sintef.no, dknut.marthinsen@material.ntnu.no Keywords: precipitation, recrystallization, modeling, concurrent precipitation Abstract.
The last two properties are mainly controlled by the grain structure/size in the material and show opposite trends with increasing grain size: mechanical strength decreases whereas the material becomes less subject to corrosion.
The final grain structure results from the recovery/recrystallization behavior during the final heat treatment after cold rolling and is often strongly influenced by concurrent precipitation.
As the precipitates are non-stoichiometric, it is necessary to track how the precipitate chemistry changes with time.
Model Predictions Model calculations have been carried out by assuming an initial deformed structure with and and an initial precipitation state with constituents having a and and dispersoids having a and .

We can find its use in special monolithic structures in industry, for fire-resistance brick, protection cladding, etc.
This process has led to large number of structures collapse and resulted in strict prohibition of use of aluminous cement in load-bearing structures.

SYNTHESIS AND CHARACTERIZATION OF NANO CuO-ZrO2 MIXED OXIDE R.R.Muthuchudarkodi1,a and C.Vedhi2,b 1Department of Chemistry, V.O Chidambaram College, Tuticorin –628008, Tamilnadu, INDIA 2Department of Chemistry, V.O Chidambaram College, Tuticorin –628008, Tamilnadu, INDIA amuthu.rajaram@gmail.com ,bcvedhi@rediffmail.com Keywords: Nano copper oxide, Nano Zirconium oxide, CuO-ZrO2, EDAX, Cyclic Voltammetry ABSTRACT Nano CuO-ZrO2 mixed oxides were prepared by wet chemical method by mixing equimolar solutions (0.45M) of cupric chloride (1.92g) and Zirconium oxychloride (3.63g) in aqueous Sodium hydroxide and refluxed at elevated temperature.
SEM morphological studies of CuO, ZrO2 and mixed CuO-ZrO2 revealed the particle distribution with uniform granular structure.
Stabilized Zirconia is used in Oxygen sensors and fuel cell membranes because it has the ability to allow oxygen ions to move freely through the crystal structure at high temperature.

The Hc value of dendritic structure was found to be higher compared to the spherical structure.
The phase also exhibited the BCC crystal structure.
The dendritic structure in 30 minutes deposition exhibited the highest Hc value compared to the irregular structures in 90 minutes deposition.

The phase structure and morphologies of the as-obtained composites were characterized and observed by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM).
The measurements showed that the different ZnO/Graphene composites prepared in this work have a remarkable structure, however, compared to the sample 2, the agglomeration of ZnO nano-particles supported on the surface of Graphene in the sample 4 is serious relativly.
