We also found that the FWHM of the (002) diffraction peak decreased to 0.26°by decreasing the sputtering pressure from 1.0 Pa to 0.5 Pa, which indicate that the grain size of the film increase at lower working pressure condition, the crystalline quality of films was enhanced.
The thickness of thin films by RBS method can be written as: , where ∆E, N, [e], are the energy loss of the particles scattered from the films on the surface and bottom, number density of molecules, molecules stopping cross section factor, respectively.

The corrosion of 304L SS in HCl medium is presumably due to the anodic dissolution either at the grain boundaries or at the metal-media interface.
Inhibitor efficiency of the compound depends on many factors which includes the number of adsorption active center’s and their charge density, molecular size and the mode of interaction with the metal surface [11] .The high efficiency exhibited by DCTU may be due to the presence of a C=S group and two –NH groups which are electron donating groups.

Metal injection molding (MIM) as a near net shape process for high production number of small intricate parts is a desirable alternative [3].
The structure also clearly shows the formation of beta (β) grain and alpha/beta (α/β) lameallae structure of sintered titanium alloy and it is shown in the Fig. 4 (a).

Introduction Fagopyrum tataricum has a scientific name of Tatary buckwheat, is one main miscellaneous grain crops [1,2].
The explants was obtained by the disinfection of buckwheat seed germination of sterility stem and leaves, adding 2.0 mg/L 6-BA, 0.5 mg/L NAA in MS culture and 2.0 mg/L 6-BA, 1.0 mg/L NAA in MS solid medium respectively, induced continuous and successive transfer and culture for 3 generations to obtain a large number of stable callus.

By taking for a basis the Eq.1 is written for one particle (radius r1αγ) separately standing in a metal, we transform it on two A1 (2) and three A1 (3) such particles in view of known relations (for volumV1α and capillary pressure 2σ1αγ /r1αγ): V = V1α + V1γ, V1α = (1/3)F1αγr1αγ , P1α – P1γ = 2σ1αγ /r1αγ , F1(3)αγ = 3F1αγ (2) A1(2)= – P1γV + (2/3)σ1αγF1αγ + (Σμini)1 ; A1(3)= – P1γV + σ1αγF1αγ + (Σμini)1 (3) Let's consider an aggregate from two or three particles with a film of metal with a tension σ2L in the field of contact (with an area of surface F2(i)L, where i - number of particles in an aggregate).
The particles NdCrO3 form in the aggregates 5-30 grains (Fig.1 A).

Material specification and experimental investigations The cold formed spring material comprised fine grained (50 μm) induction hardened tempered martensite steel with elemental composition given in Table 1 and mechanical properties: Ultimate tensile strength 1921 MPa; Young’s modulus 225 GPa; Poisson’s ratio 0.284.

Surface texture (grain) of the early research work can be traced back to 1977.
Currently , various models used to analyze the lubrication characteristics of texture surface have been established, and a large number of relevant experiments are conducted.

A visual method for obtaining preliminary information about the color, number of layers, the thickness of each layer, connection with the finishing layer was used at the first stage of the investigation of the plaster layer of interior finishing (stucco and paint) [2].
Nanostructured microscopy allows to: - the most accurately identify original (authentic) elemental composition of the mortar; - to analyze the changes in chemical composition of the mortar during operation from environmental influences (this explains the presence of lead in the mortar mixture); - determine the microscopic structure and grain size in order to control the properties of new mortar mixtures in the restoration of damaged areas of the plaster layer.

This phenomenon can be explained by increasing temperature increases acetylation reaction rate and consequently the number of acetyl group that substitutes carboxyl group would also increase.
Parameter Examination of Sorghum Grain and Total Analysis Effects of Lactic Acid and pH on Sorghum Flour Baker's Yeast by Fermentation (Saccharomyces cereviceae).

With the development of the smelting process, the number of mono-copper sulphide decrease and copper oxide increase, added to the influence of during converter slag-forming, which result in the disseminated particle of copper fineness and unevenness[13-15].
However, the digenite, presenting as medium-fine grains, appeared on the boundary of fayalite and glass phase with more fine crystal size.
