The phase structure of samples was characterized by X-ray diffraction (XRD).
In addition, the crystal structure of Ba-Ta2O5 was studied with X-ray diffraction.
XRD and MB degradation measurements The phase structure was identified by X-ray diffraction (D8-ADVANCE, Bruker, Germany) with Cu Kα (λ= 1.5406 Å) radiation at a scan rate of 0.02 2θ S-1.

The nanoscale fracture surface morphology respects the micromechanisms of the failure of the amorphous structure.
The failure is performed in a narrow region via local softening of the amorphous structure in front of the crack tips.

The effect of Fe dopant from different source of Fe to the crystal structure and ionic conductivity of 8YSZ samples were investigated.
Results and Discussion Structure Characterization.
The present of Fe from iron nitrate source easily diffuse in the fluorite structure and distorted the crystal lattice and has resulted in the formation of monoclinic phase.
The results were in contrast with what Nakajima et al. [5] found where they reported that the crystal structure of cubic phase was not changed by Fe doping.

However, if the thickness was high e.g. 600 µm the film surface had more wavy structure.
The tablets without coating show clearly the porous structure.
The porous structure disappeared and the surface was smoother after the coating process.
At higher film thicknesses, the films got more wave structure (Fig. 4).

The dissolution of KCa(PO3)3 phase formed a pore
structure in KCa(PO3)3-CMP samples.
Introduction Among various types of biomaterials, biodegradable calcium phosphate ceramics has been considered for use in dental and medical areas for the repair and reconstruction of diseased or damaged bones due to the fact that they have a good solubility in biological environments, similar chemistry to bones and diversity in chemical composition [1].
But, the dissolution of KCa(PO3)3-CMP samples were found with the formation of pore structure, (Fig. 3).
The dissolution of KCa(PO3)3 phase formed a pore structure in KCa(PO3)3-CMP samples.
There is a possibility to control the dissolution rate of CMP by adding KPO3 and to form porous CMP structure for the use in bone regeneration.

Laminated templates electro-deposition (LTE) is a small-sized metallic-structure
fabrication technique based on template-patterned depositing.
Introduction Laminated templates electro-deposition (LTE) is a newly-developed technique which by integrating small-size electroforming with the discrete piling-up principle [1, 2], achieves small-scaled metallic-structure fabrication.
Compared to other conventional technologies in this type, it features arbitrary 3-dimentional structure construction, extensive material adaptability as well as less cost in maintenance and equipment [3].
Although the articles that have been made belong to simple structure, the proposed method has proved its technical feasibility and can be improved in the further programs.

Results and Discussion Structure analysis of the rare earth complexes.
After β-diketone was chelated with rare earth ion, the bands of C=O, C=N, C=C were weaken by conjugate structure of C=O-Eu and lead to vibration peak redshift.
It can be seen that there is no mass loss occurs below 200℃ which indicates the absence of water molecular in its structure.

Abstract.
A novel intumescent flame retardant oligomer containing phosphorous-nitrogen structure (PSPTR) was synthesized and characterized by Fourier Transform Infrared (FTIR) and Mass Spectrometry (MS).
Recently, the intumescent flame retardant containing phosphorous-nitrogen structure has been received more and more attentions owing to the environmental friendly consideration [4-8].
The structures of PSPTR and its intermediate were characterized by FTIR and MS.
The FTIR spectra of DAMT: 1582, 1528, 802 cm-1 (triazine-ring structure); 3347, 3217, 1681 cm-1(-NH2).

Increasing time did not result in any significant changes of the product appearance and structure.
The synthesis temperature in this case was sufficient for the beginning of ZrO2-Y2O3 solid solution crystal structure formation.
Thus, the final crystalline structure of ZrO2-Y2O3 solid solutions is determined solely by the presence of Y2O3 stabilizing additive and does not depend on the conditions of combustion synthesis.
