Introduction Yttria-stabilized zirconia (YSZ) as an electrolyte and lanthanum-strontium manganese oxide (LSM) as a cathode are still the most widely used materials for solid-oxide fuel cells (SOFCs).
Different quantities of carbon as a pore former were added to the slurries based on cathode material.

Hence our interest in the microspectroscopical properties of materials.
Accordingly, this paper, as presented to a meeting on the mechanical behaviour of materials, is in the nature of a non-specialist review.
After satisfactory validation, the model was used for testing all the spectra in the central region of the sample spanning the boundary between the two materials.
The boundary between the two materials runs vertically up the centre of the image.

The rare earth luminescent materials were prepared urgently which is matching with near ultraviolet and blue LED chips, especially the red phosphor.
The structure of alkaline earth and rare-earth elements BaY2O4 oxides was similar with the CaFe2O4, they belong to the triangular geometries of rare earth ions [6], the position of Y3+ ions may be substituted trivalent rare earth ions to form a luminescent center, so BaY2O4 can be become a matrix of light-emitting materials.
In this paper, the process of preparation method relatively mild and get high-quality light-emitting materials in a short time compared with a single preparation process after we combined the sol-gel method and combustion method.
This result indicates that a small amount of Eu3+ doping did not affect the structure of BaY2O4 host materials.

Materials and experimental method Experimental materials The main raw materials were representative samples which used in mass concrete structure engineering construction, there are: China resources (Pingnan) cement P•II42.5, Zhengjiang Huayuan class I fly ash, Tangshan DunShi S95 slag, sand of Xijiang river, gravels from Xinhui, Jiangsu Subote water reducing agent JM-PCA.
In consequence, as an effective evaluation of the cracking resistance of concrete materials, the thermal stress testing method need to be established based on the standardization research, then get accurate and effective evaluation indexes according to the standard test method.
Theoretically speaking, archived data matching mode considered the effect of cooling process and the influence of different temperature rise of different concrete materials.

Introduction Superalloys are an important class of complex materials that exhibits excellent mechanical strength and creep resistance at high temperatures(often in excess of 0.7 of the absolute melting temperature), good surface stability, and corrosion and oxidation resistance [1].IN738 is belong to Ni-based superalloys materials used for blades and buckets for hot sections turbine engines [2].
HIP+HT can improve creep strength which is important factor for application of materials at high temperature.
