Colloidal chemistry enters to some degree every technological problem involving clay and liquids, such as problems of soil consolidation, plant nutrition, molding of ceramic objects, and the circulation of drilling fluids in an oil well.
For instance, network structures may collapse when water is displaced by less polar compounds.
Kaolin suspensions form card-house structures, in which the positively charged edges are attracted to the negative surfaces forming three dimensional structures.
The presence of less organic compounds or multivalent anions (polianions) recharging the edges destabilizes these three dimensional structures increasing its dispersibility [4].

In welding for the corner joint of box-column structure with a ultra thick plate of 80mm,
lamination occasionally occurs along the mid-thickness of the flange plate.
Introduction With increasing application of large scale steel structures to buildings, bridges, ships, and offshore structures, the use of ultra-thick plate box columns has increased and this trend is expected to be continued[1].
This linear band leads to discontinuities in chemistry, resulting in inhomogeneous microstructure and properties through the plate thickness direction.
During welding of such plates for high restraint structures, an internal crack, known as lamination, occasionally occurs along the linear discontinuous layer in the mid-thickness of the plate, owing to the combined effects of ductility loss in that reason and applied external force[2].
The main difference in chemistry is sulfur contents, showing 40 ppm and 20ppm respectively.

Keywords: Aluminium oxide, Spray pyrolysis, Stainless steel, Thin-films, Zirconia oxide.
Alumina exhibits largely open porous foam-like structure (Figs. 4a and 4b).
The structure of alumina film consists primarily of sphere-like particles (Fig. 4c), with diameters smaller than 50 nm.
Analysis of SEM micrographs revealed that ZrO2 and Al2O3 films have micro concavities, open porosity and structure irregularity, which would be advantageous to a possible use of the deposited oxide films as catalysts supports.
SEM analysis shows that ZrO2 and Al2O3 films have micro concavities, open porosity and structure irregularity. 20 µm 5 µm 0.25µm 20 µm 5 µm 0.25µm Our results have shown better adhesion of the ZrO2 film than of the Al2O3 one to the SS substrate.

The difference between amorphous and crystalline structure in XRD pattern is determined by the peaks.
The obtained result of XRD pattern as shown in Fig. 1 confirm that the crystalline structure is absent in all glass samples.
The optical absorption study in glass materials is crucial to relate with the theory of electronic structure of amorphous materials.

The crystal structure and the electronic properties of the TiC and its surfaces may significantly influence the combination between the TiC and the metal matrix.
The experimental [3, 4] and theoretical [5-7] studies on TiC cover the fields of materials science, physics as well as chemistry.
In addition, electronic structure and adhesion of polar TiC(111)/Ti interfaces and Al/TiC interface have also been examined by Liu et al. [9].
The studies on TiC experimentally and theoretically involve the fields of materials science, physics as well as chemistry.
The minimum total energy of the structure is achieved by relaxing automatically the internal coordinates using the Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm.

Results and discussion
The structure of the as-deposited ErAlO film is checked by XRD, which was collected between 20°and 60°.
Particularly, luminescence around 500nm was regarded as resulting from dangling bonds of the amorphous structures for the un-annealed samples.
Kasuya [9] reported intense photoluminescence in the green and red regions excited by the 800nm laser beams which consists of more than 10 peaks corresponding to the fine structures.
