Preparation of carbon supported nanometal catalysts were realized through the carbonization of metal precursor doped carboxymethyl cellulose under nitrogen condition. This carbon supported nanometal catalyst exhibited good activity in the reductive amination of amine. The results suggested a promising one-pot route based on economical and sustainable biomass towards the development of value carbon materials as effective catalyst for C-N bond synthesis reaction.

Iron oxides-doped carbon microspheres composites were synthesized by one-pot hydrothermal methods using Fe (NO3)3·9H2O as the iron source and glucose as the carbon source. The morphology, particle size and crystal structure can be controlled flexibly by altering the concentration of ferric salts and glucose. The SEM and XRD were used to characterize the physicochemical properties of materials. The SEM images indicated that the composites were microspheres, and as the salts concentration increase, adhesion occurred between microspheres. The XRD results showed that the composites were composed of Fe3O4 and amorphous carbon. The materials were applied to photocatalytic degradation of dye wastewater and possessed high performance.

Ti-Al-Nb ternary phase diagrams were calculated by Thermo-Calc software. The analysis of the calculated vertical sections of Ti-Al-Nb phase diagram indicated that when Nb content is fixed at 5at.% and Al content is lower than 52.3at.%, the primary phase would be β phase during solidification. With 10 at.%Nb and Al content lower than 55.8at.%, or with 15 at.%Nb and Al content lower than 56.9at.%, the primary phase would be β phase. The vertical sections of Ti-Al-Nb ternary phase diagram were further simplified into pseudo-Ti-Al binary phase diagram. According to the pseudo-Ti-Al diagram, the expression of the aluminum equivalent was obtained in Ti-Al-5Nb ternary alloys.

The 3D Finite Element Method (FEM) model of engine connecting rod was established in this paper. And, nonlinear analysis of engine connecting rod was made, Stress distribution of the connecting rod under condition of maximum stretching and maximum compressing was simulated. The result shows that the results coincide with the actual results and connecting rod can satisfy the strength requirement, the method turns out to be very effective in practice.

Polycrystalline aluminum nitride (AlN) films were deposited on Si (111) substrates by radio frequency (RF) magnetron sputtering method in an nitrogen (N2) + argon (Ar) gas mixture. The effect of the preparation conditions- sputtering pressure (p), sputtering power (w), gas mixture (Ar/N2) and post-deposition annealing treatment -on the properties of AlN films were investigated by means of X-ray diffraction (XRD). Highly c-axis oriented AlN films were obtained with optimized growth parameters: p=0.3Pa, w=400w and Ar/N2=2.

In this paper, the finite method is applied and ABAQUS software is used, the vortex flow field is loaded as boundary condition of wraps. The stress and deformation in scroll under the action of gas pressure, temperature load and both of them is analyzed, the stress distribution and deformation of wraps in different shaft rotation angles is discussed, the stress distribution and deformation discipline of wraps are also respectively obtained. The results show that the overall stress and deformation in scroll are the largest when compression chamber is moving near the vent position and the thermal deformation is the main factor of affecting the overall deformation of scroll.

In order to improve electric efficiency of solar cell arrays and obtain available heat energy, the solar trough concentration photovoltaic/thermal system has been constructed and the experiment performance and analysis of solar cell arrays have been carried out. The results show that in concentration the thermal efficiency of system linearly decreases with the temperature of cell arrays increasing. In non-concentration, the maximum power output (Pm) temperature coefficients of single crystalline silicon solar cell, polycrystalline silicon cell array and super cell array are -0.2 W/(m2·°C), -0.15 W/(m2·°C) and -0.16 W/(m2·°C), respectively.
