Thus, development of devices on the basis of such structures requires the stability of their properties and understanding the processes occurring at the interface between the phases "matrix-embedded nanoparticles" [2].
Methods The structure of the obtained samples was investigated by SEM (Quanta 650 FEG, FEI).
In this case, peak observed at 1078 cm-1 correspond to stretching vibration of Si–O(−Si), belonging to a more linear and less cross-linked structure [8].

Introduction Nanoporous metals are innovative materials with pore size range from a few nanometers to dozens of nanometers, which have attracted much attention due to their co-continuous internal structure, higher specific surface area, good conductivity and other unique properties.
Chemical composition and physical-chemistry data of the electrolytes.
Compared with the dealloying process of Cu68Zn32, to avoid Cu component fall off the substrate and keep plenty of time for reunion growth of Cu so that forming double continuous nanoporous structure during corrosion of Zn component, the corrosion rate of Zn in Cu36Zn64 should be reduced, therefore relatively low concentration of HCl (0.05M) is used as corrosion solution.

X-ray diffraction (XRD) was used to study the crystal structure of theresulting copper coatings.
The microstrip patch antenna structure comprises radiating patch, dielectric layer and ground plane.
The compact structure of the copper coating layer is confirmed by the cross-section image, Figure 3b, where cavities or pores can hardly be observed.

Porosity of the Ternary Gypsum-Based Binders with Different Types of Pozzolan DOLEŽELOVÁ Magdaléna1, a * and VIMMROVÁ Alena1, b 1Czech Technical University in Prague – Faculty of Civil Engineering – Department of Materials Engineering and Chemistry, Thákurova 7, 166 29 Prague 6, Czech Republic amagdalena.dolezelova@fsv.cvut.cz, bvimmrova@fsv.cvut.cz Keywords: Gypsum, ternary binders, crushed ceramic, microsilica, GBS, porosity, mechanical properties, moisture resistance.
Samples with microsilica stored in water (C-W) have a higher porosity but a finer porous structure than samples stored in laboratory condition (C-A).
According to the pore distribution the products of pozzolan reaction refine the porous structure of materials, especially when stored in the water.
Samples with microsilica (C-A, C-W) and blast slag (D-A, D-W) have the same compressive strength regardless to type of storage, but results of porosimetry shows changes in the porous structure yet.

Effect of Sintering Temperature on Al2O3/TiAl Composite from Ti-Al-TiO2-Eu2O3 System Fen Wanga, Xiaofeng Wangb, Jianfeng Zhuc and Liuyi Xiangd Key Laboratory of Auxiliary Chemistry and Technology for Chemical Industry, Ministry of Education, Shaanxi University of Science &Technology, Xi′an 710021, China awangf@sust.edu.cn, bwang3164153@126.com, czhujf@sust.edu.cn, dsixone317@163.com Keywords: TiAl; Al2O3; Sintering Temperature; Microstructure; Mechanical Property Abstract.
It can be found that all of the diffraction peaks shift to large angles and became increasingly broad in width with the temperature change from 900 oC to 1200 oC, which can be refined of the coarse-grained structure.
When the sintering temperature up to 1300 oC, the formation of overheated structure.
In addition, the decomposed rare earth element has a tendency to form a variety of compounds with Al, which modifies the structure of Al2O3/TiAl by well distribution along the matrix with fine grain itself.

In the course of service exposure, these alloys undergo manifold degradation processes such as coarsening of precipitates and the subgrain structure as well as the formation of unwanted phases such as the modified Z-phase, which grows on the expense of the important strengthening phases MX and M23C6.
