Thermodynamic calculations were performed using a HSC Chemistry Ver 4.1 computer programme [11].
Scale morphology Studies of scale morphology aimed mainly at the determination what effect the temperature and corrosive environment might have on its structure and porosity.

The TGO formation process is a complex function of chemistry of both, the bond coat and the TBC system as well as the heat treatment conditions and oxygen partial pressures employed [1, 2].
While the dark contrasted TGO sections primarily represent alumina-rich Al-Y-Oss compositions a composite grain protruding into the bond coat surface shows a significant Z-contrast change due to different yttrium concentrations in the core and shell structures respectively.

Introduction Austenitic stainless steels are widely used as structural materials and functional materials in modern industries such as chemistry, aerospace, auto-mobile, food production and medical fields for its good corrosion resistance and processing properties [1-3].
It could be seen that the part has a flat surface, and the sintered metallic structure looks dense and uniform.
A higher sintering temperature resulted in higher densification, smoother pore structure and smaller pore size.
This diffusion is useful in controlling the densification process during sintering, therefore, a denser structure is achieved at higher sintering temperature [17].
It is seen that, at higher sintering temperatures, a denser structure is formed due to higher diffusion rates [17].

Simulation Results The MAS in (1D) dimension structure contains up to six DTB molecular units packed in the parallel geometrical arrangement.
With Ef close to LUMO, the conductance gap and VIP (the voltage interval between two peaks of to the same molecular structure (Fig. 3b)) are found to decrease, while the peak of the conductance increases.
The magnitude of the Fermi level position for each molecular structure (N=1,2, 3, 4 and 6), is indicated in Fig. 2, curves (Efo).
The magnitude of the Fermi level position for each molecular structure (N=1,2, 3, 4 and 6), is indicated in Fig. 2, curve (Efo+3d).

The potentiality of PTC barium titanate ceramic is demonstrated not only by the number of applications but also by the expertise acquired on structure-properties relationships in this material [5].
The crystal phase of BaTiO3 was tetragonal structure matched exactly with JCPDS file no. 76-0744.
Literatures reveal that in order to get high dielectric constant, the crystal structure should have high tetragonality [7].

However, the milled samples show the presence of B2 intermetallic structure and also XRD-reflections of α-phase which is an aluminum hydroxide (Al(OH)3).
The α-phase has a hexagonal structure and is well known in mineralogy as bayerite.
On the other hand, the intermetallic bcc structure and the atomic relationship used in the present study (Fe40Al60) could favor the hydrogen embrittlement reaction [15].
The atomic packaging as consequence of bigger interatomic distances is smaller than in the fcc structure, allowing the hydrogen to diffuse more easily through the lattice’s interstices and the structural defects.
Therefore, aluminum centered in bcc cells, react more easily with water, unlike when pure aluminum has typical structure fcc.

As well, porous structure of the synthesized powders are introduced.
The porous structure was due to the development of foams in the thick solution during the stirring and drying process.
The crystallized powder also showed porous structure.
The SEM micrograph of the crystalline YAG revealed soft and porous powder structure.

The structure of the thin films was characterized by a Philips X ，Pert-MPD X-ray diffraction spectroscopy（XRD）and a Philips XL30E Scanning Electron Microscope (SEM).
The XRD spectra indicates that the structure of the SnS:Ag films are strongly influenced by the doping concentration.
It indicates that all the films show an orthorhombic crystal structure.
The four images of the SnS films seem to be similar which exhibit granular surface structures.

Chemical structures of both materials are shown in Scheme 1.
These diagrams can be used for the determination of model electric circuits of the studied structures.
