In this context, epitaxial processes are one of the key techniques to harness SiC desirable properties for device fabrication, but a major drawback for such processes is that they are quite cost intensive [2].
After the assessment of material reorganization after annealing, the crystallographic structure of the closed pores surface is investigated.
Careful examination suggests that the superficial layer on the inner pore wall may not follow the same ordered crystalline structure as expected from the bulk material.

Abstract.
In this work, conceptions developed by the authors about the evolution of a macroscopical substance structure in SHS-processes - structure determined by the common porosity, its volume distribution, size of pores or to elements forming the porous structure, specific surface, change in sizes and forms of burned test materials, presence of cracks, etc are stated.

Abstract.
Titanium mesh was chose as support material for gas diffusion layer and catalyst layer but not traditional carbon paper or cloth.
The detailed choice of each layer was explained as follows: (1) The choice of titanium mesh material: the 250 μ m thickness of the titanium mesh was chose for the support layer of anode and cathode, whose diamond mesh size was 0.2mm × 0.5mm
Prototypes preparation of S-MEA Experimental materials.

Abstract.
Experimental High purity of CaCO3, Li2CO3, Nb2O5 and ZrO2 raw materials (>98%) were batched stoichiometrically.
Moreover, the liquid phase segregated at grain boundary, which is amorphous materials with the ions weakly bonded in their network, dissipates and absorbs electromagnetic energy heavily [12], resulting in the substantial increase of THz absorption in highly B2O3 doped CLNZ ceramics.
The Natural Science Foundation of Guizhou Province (No.20132092) and the Key Project of the Education Department of Guizhou Province (No.2013070472) are also acknowledged for partial financial support.
