Epitaxial Growth of “Strain-Free” Indium Oxide Films on (111) Yttria-Stabilized Zirconia by Metal-Organic Chemical Vapor Deposition Yi Zhuo1,a*, Zimin Chen2,b and Shengdong Zhang1,c 1School of Electronic and Computer Engineering, Peking University, Shenzhen 518055, China 2State Key Laboratory of Optoelectronic Materials and Technologies, Sun Yat-Sen University, HEMC, Guangzhou 510006, China.
In combination with zinc oxide (Eg ≈ 3.2 eV), gallium oxide (Eg ≈ 4.9 eV) and aluminum oxide (Eg ≈ 9 eV), band-gap engineering and heterostructure device for electronic and optoelectronic applications are foreseeable.[1, 2] For decades, however, In2O3 is only used as transparent electrode material in light emitting diodes, photovoltaic devices, and flat panel display, usually in the form of polycrystalline thin films deposited by sputtering technique. [3-7] The realization of real semi-conductor devices typically requires highest crystalline quality which is commonly achieved by epitaxial growth methods.[8-10] The thermodynamically stable phase of In2O3 under ambient conditions is the body center cubic bixbyite structure (space group Iα3) with lattice parameter of a = 10.117 Å.[1, 11] Since single crystalline In2O3 substrates are not commercially available, epitaxial In2O3 films have been usually grown on yttria-stabilized zirconia (YSZ) substrates.[12-14] YSZ at the 17% Y doping level

Biodegradation of the specific compounds (such as xenobiotics or trace compounds) is feasible if sufficient microbial growth occurs through utilization of natural organic material and if the secondary-utilization kinetics of the micropollutants is sufficiently rapid.
Sometimes, biological oxidation and respiratory action was vigorously promoted in the presence of a little key zymogen, in result of increasing removals of organic substrates.

Dynamic analysis of concrete frame structure with story-adding steel structure at the top Xianghong Sun1, a, Lieping Xie1,b and Feng Ji1,c 1School of Civil Engineering, Chang’an University, Xi’an, Shaanxi, 710061, P.R.
The Key Issues of Existing-structure with Story-adding Analysis Strengthening Design.
The selection of the damping parameters should be chosen by the material of main stress components, and selecting the damping parameters for the overall structure.
The damping coefficient of the reinforced concrete composite structure is 0.05, the damping coefficient of the steel structure is 0.02, and the damping coefficient is determined 0.04 according to the engineering experience value.
In modal analysis, steel and concrete are considered to be elastic material.

According to literature [12, 13], the groove area density (Sp) and the groove aspect ratio (e) are the two keys parameters for the surface texturing, and they could be defined as follows: Sp =( 2rp / ζ)*100, e = hp / 2rp Fig. 1 Schematic drawing of PR-CL interface with oil grooves.
According to Greenwood and Tripp's model of asperity contact [10], assuming that the surface roughness of the piston ring and cylinder bore to be isotropic, the asperity contact pressure can be expressed as: Pasp=16215π(ηβσ)2E σβF2.5H (5) Where β is the radius of curvature of asperity peak, η is the asperity density, and É the composite elastic modulus of the surface materials.
