No remnants of NiO platelets formed on the surface layer were observed after oxidation at 960°C, while many small pyramid structures on the surface layers was observed.
The formation of the porous structure of the oxide scale formed on sample A also might be associated with the substrate crystal structure.
It also shows that the different crystal structure for sample B, such as high preferred orientation, might be contributing to the high oxidation resistance for Ni coatings.

The ideal structures must be formed by an interconnected porous network with a wide variety of pores sizes, large pores that allow tissue ingrowth and vascularization of the new formed tissue [14], and pores in the microporous range to promote protein adhesion and consequently cell adhesion and proliferation.
SEM analysis of the porous structures of the sample before immersion revealed a microstructure composed of various size pores (refer with: Fig.3a).
The special structure improves the activity of chemical reaction with physiological body fluid for biomaterials, and also provides a great deal of "crystal nucleus" for the aggradation of hydroxy- carbonate-apatite (HCA).
Conclusions The bioglass reinforced tricalcium phosphate scaffold possesses an inter-connectively porous structure with the pore diameters from 100 to 500 µm.

Introduction Atomization technology is extensively applied into agriculture, coal, chemistry and other industry.
But the process of atomization is so complicated, because the geometrical structure of nozzle and the inlet pressure of nozzle and some others factors are all affecting the water droplet generation.

Introduction High quality thermal oxides on silicon carbide are a key to the fabrication of future generations of field effect and other electronic device structures.
This corona-based method, described in [5], facilitates the rapid evaluation of processing effects while the complications and cost associated with the fabrication of capacitor structures are avoided.
The afterglow gas chemistry used in this work was O2 and 10% volume flow of N2O.
The SiC sample is held on a vacuum chuck that moves in sequence under a charging structure and then under the potential probe.
Evidence of the effective removal of carbon from films grown in the afterglow process is seen in the insert of Fig. 2 where scatter plots for 300Å films show the dependence of QC versus VCPD, or COX when the oxide-semiconductor structure is biased in accumulation.

Introduction One of the by-products of steel industry is steelmaking dust, formed during steelmaking processes, and its chemical composition strongly depends on the chemistry of the kind of processed steel.
In every sample, the calculated fraction of an amorphous component contained also the part of the phases of the unknown crystal structure.
Unfortunately, there is still no structure data of the identified lead compounds, so - excluding lanarkite - there was no possibility to include these compounds in the calculated pattern.
The calculated values of "amorphous content" contain the fractions of lead compounds which structures are unknown and cannot be used in Rietveld refinement quantification.
But in these investigations, a considerable rise to χ2 values comes from not fitted diffraction lines of phases of unknown structures.

Plasma diffusing technology may endow the workpiece with well wear resistance, fatigue resistance and causticity resistance through changing the chemical composition and structure of the workpiece surface material.
The morphology and phase structure of the duplex layer was observed and examined by using Quanta200 scanning electron microscopy (SEM) and D8 ADVANCE X-ray diffractometer(XRD), respectively.
Results and Discussion Morphologies and Structure.
It can be seen that the FeS solid lubrication duplex layer has loose structure, and the sulphide grains pile layer upon layer, and their dimensions are very fine and in micron nano scale.

The C-H bending vibration comes around at 847 cm-1and also the corresponding intensity of Bi-S bond (PVA-Bi2S3@CS) are decreased for the reason that the size of Bi2S3 NRs converted into very small size, so easily adsorbed on CSs as shown in Fig.1(d). 3.2 Structural and Morphological Studies The positions and relative intensities of all the peaks are in good conformity with those of the orthorhombic crystal structure of Bi2S3 and are indexed according to JCPDS card number 17-0320.The broadening of the peaks clearly indicates that the size of the product is in Fig. 2: XRD spectrum of Bi2S3 NRs coated on carbon spheres, (a) - without PVP, (b) - low Concentration of PVP, (c) - high concentration of PVP.
While increasingthe time duration (24 h), the nanorods were formed as flower like structures on the carbon spheres as shown in Fig.4(E-G).

The calculation of the pressure and the temperature dependence of the thermodynamic properties of VSb2 material is obtained from that of the electronic structure, within the framework of the Quasi-Harmonic Approximation (QHA).The thermodynamic properties such as the primitive cell volume V(Bohr3), the bulk modulus B (GPa), the heat capacities CV(J.mol-1.K-1) and CP(J.mol-1.K-1), the thermal expansion coefficient α (K-1), the Grüneisen parameter γ, and the Debye temperature qD(K) have been studied depending on the temperature (T) in the range [0°K; 500°K], and the pressure (P) in the interval [0 ; 15 GPa].
