A number of publications exist in the literature on the synthesis of manganite perovskites.
The size, shape and distribution of the grains were examined using JEOL-JSM 6300 scanning electron microscopy (SEM).

Recently, it has been shown that ZnO is a versatile material in terms of down sizing and has been prepared in a number of interesting nano and microsized shapes such as nano needles [5], prismatic nanorods [6], bone-like nanorods [7] nanoflowers [8], nanofibres [9], nanopetals [10], nanotube arrays [11], nanowhiskers [12], nanowires [13] and hollow nanospheres [14].
The cross-sectional grain sizes of the ZnO nanoparticles measured from SEM images were in the range of 52 to 86 nm.

The film prepared from the suspension containing 0.6 gL-1 bioglass contained larger number of the bioglass particles, compared to the film prepared from the suspension containing 0.3 gL-1 bioglass (Fig.2a,b).
It is in this regard, that the properties of sintered HA with large grain size are different from the properties of natural nanostructured HA.

Considering the result of X-Ray Photoelectron spectroscopy and X-Ray diffraction of as-prepared nanocapsules, it is identified that the shell of the nanocapsules consists of most BiFeO3 and few Bi2Fe4O9, the core of nanocapsule consists of Fe crystal grains.
The anisotropic energy of small size particles, especially in nanometer scale, may be remarkably increased due to the surface anisotropic field affected by very small size effect, in addition, a large number of lattice defects and interfaces can bring about the increase of effective anisotropy field, in other words, the magnetic BiFeO3 coated Fe nanocapsules own a relatively high effective anisotropic energy and the resonance frequency may shift to the higher frequency 11.3 GHz, which would be significant for their use as electromagnetic wave absorption materials in the microwave range.

With prepolymerization time increase, the particle size of latex grain change smaller, the viscosity of system decreased, and the property of staining resistance is enhanced.
But when the quantity of grafted more than 5%, the performance of adhesive become worse, the reason is that there are large numbers of Si-OR groups which can form crosslinking structure, it can increase the crosslinking density of the membrane, it is conducive to improve the water resistance of the membrane.

LC-OFC (LARGE CRYSTAI OFC): Large crystal oxygen free copper is to make the crystal grain of oxygen free copper that has high conductivity power grow up through mechanical process and hit treatment, and reduce signal distortion caused by crystal boundary of wires.
In high frequency wire, silver is used as surface material in the level of number signal.

Of a number of processing methods to produce nanoparticles, a sol-gel process has been known to be a promising synthetic means that offers several advantages such as high purity, high chemical homogeneity and lower calcination temperatures [2].
The powder treated at 900°C showed hexagonal-shaped grains with crystallite size above 500 nm.

Since the lattice style of CrN is not the same as that of austenitic stainless steel, the precipitation of CrN needs so much grain boundary energy that only high temperature can make the chromium atom bind together to obtain enough critical nucleated measurement, forming the lattice of CrN balance phase.

Introduction Theoretical investigation of the stresses in solid and annular disks rotating at high speeds has been receiving widespread attention due to a large number of applications in engineering like turbine motors, flywheels, gears, shrink fits etc.
The composite shows a steady state creep behavior , which may be described by following Sherby’s law of the form [1977], ; where where be the effective strain rate, effective stress, the stress exponent, threshold stress, a constant, lattice diffusivity, the sub grain size, the magnitude of burgers vector, Young’s modulus.

.% Mo), indicate that films with more incorporated Mo have larger crystallite/grain sizes.
The increased reversibility in Mo/W mixed films may be related to a reduction in the number of sites where lithium ions could bind the matrix irreversibly [4].
