SiC ceramics are widely serving as ceramic composites matrix materials of high-velocity vehicles structures against extremely heating and oxidation for their sustainability at high temperature, and are also high temperature thermoelectric materials, which can transfer heat to electricity by temperature difference. Both of these advantages brought out an idea of generating electricity from aerodynamic heat by thermoelectric SiC structures on supersonic vehicles. A simple nose-tip thermoelectric module is set up, in this work, to predict the thermoelectric performance of SiC ceramics in a supersonic air flow environment (Mach number 3). The flow field parameters, temperature difference and temperature distributions of the module have been simulated by computational fluid dynamics methods. The thermoelectric performance and effect of Thomson heat were discussed. The maximum power output and energy efficiency reaches 0.0027 W and 0.0036 %, respectively, at 230 K temperature difference and a current of 0.122 A. The Thomson heat increases directly with the output current, and at a current above 0.15 A, over 50 % of the generated power has been turned back to thermal heat, resulting in the effective output power as well as energy efficiency decrease rapidly. The thermoelectric efficiency would be increased on higher-speed vehicles by enlarged temperature difference.

Photoreduction of CO2 to hydrocarbon needs the urgent development in effective and low-cost technology to mitigate global warming caused by atmospheric CO2 and other poisonous gas from fossil fuels combustion. In this work, Cu-decorated TiO2 nanorod films were synthesized by the hydrothermal method followed by electrochemical method with copper ion solution concentration (1-6mmol/L)and potential voltages (-1.6 and -1.2v). A combination of characterization methods XRD, SEM, and UV-Vis DTS, TEM, XPS were used to evaluate the interaction between titania and decorated copper. Their photocatalytic activities were evaluated by the reduction yield of CO2 under UV irradiation. The methane yield of Cu-TiO2 showed an obvious increment as a result of localized surface Plasmon (LSP) of Cu particles. These arrays are important for photocatalysis and for the development of the photoreduction of CO2 on the global warming.

In this research, the adsorption of toluene was tested with MCM-41 and mesoporous silica materials synthesized from spent solar panel and glass. The synthesized solution was mixed with cationic cetyltrimethyl ammonium bromide (CTAB) surfactants. The prepared adsorbents were characterized by nitrogen adsorption-desorption analysis, transmission electron microscope, scanning electron microscope - energy dispersive spectroscopy, X-ray powder diffractometer and Fourier transform infrared spectroscopy. The results showed that the surface area, large pore volume and pore diameter could be up to 1280m2 g-1, 0.82cm3 g-1 and 2.62 nm, respectively. The crystal patterns of mesoporous silica materials were similar of MCM-41 from TEM image. In this study, the effects of operation parameters, such as contact time and mixture concentration, on adsorption performance were also assessed.

A one-dimensional unsteady heat conduction simulation for downhole heat exchanger (DHE) is established in this paper, and the Lattice Boltzmann Method is used for the numerical simulation. In the model proposed, the influence factors of the temperature gradient with well depth, well pipe diameter, thermal properties of pipe, circulating water flow rate and inlet temperature on the outlet water temperature or heat output have been taken into account. According to the DHE experimental data, a comparison was made between the results of simulation and experiment. The result shows that the model can be used to predict the outlet water temperature of DHE at given conditions, but the deviation from the experiment increases with time, which is probably resulted from the natural convection occurred in the aquifer, and its intensity is gradually strengthened.

Paraffin microemulsions are multifunctional thermal fluid consisting of water as the continuous phase and paraffin as the dispersed phase. They can store or transfer a large amount of thermal energy by using the latent heat capacity of the paraffin during the phase transition as well as the sensible heat capacity of water. In this study, hexadecane O/W microemulsions were emulsified by an ionic surfactant SDS and a co-surfactant butanol. The phase behavior, effective stability, droplet size and thermophysical properties, such as latent heat and dynamic viscosity, were investigated experimentally. The results showed the prepared microemulsion with 30 wt.% hexadecane has expected high heat capacity about 93.4 J/g and low viscosity about 21 mpa·s. The average droplet size is 73 nm. The results indicate that they have potential applications in thermal energy storage and transfer.

γ-Al2O3 modified with different impregnants has been studied for COS removal efficiency under micro-oxygen conditions. γ-Al2O3 modified with 5%KOH is found to have markedly enhanced its adsorption purification ability. In the adsorption purification process, the reaction temperature and oxygen concentration of the gas are determined to be two crucial factors. After heating regeneration, the adsorption efficiency of spent sorbent (K/γ-Al2O3-R1 and R2) were still effective and stable. And it will be of use after heating regeneration. According to the current study results, the γ-Al2O3 impregnated with 5%KOH promises a good candidate for COS adsorbent.

The process of preparation of glass ceramics from black shale is briefly described in this paper. ICP-MS analytical method is used to obtain glass-ceramics REE content, RE eigenvalue and distribution model. It shows that rare earth elements (Ce, etc) are relatively concentrated in glass ceramics. It's proved in a series of tests that the flexural and compressive strength of glass-ceramics is superior to marble and granite because of traces REE containing in glass-ceramics. In addition, the results of scanning electron microscopy tests show that REE are as main factor affects the crystallization temperature and color of glass ceramics.

In the present study, core-shell Al2O3 was synthesized by hydrothermal method and employed as support for the preparation of Ni/Al2O3 catalysts via an impregnation method. The toluene thermal-reforming was investigated in a fluidized bed reactor using these core-shell Ni/Al2O3 catalysts. The catalysts were characterized with TEM, BET, XRD and H2-TPR techniques. Compared with the catalysts supported on commercial Al2O3, core-shell catalysts exhibited higher specific surface areas, smaller Ni particle sizes and higher catalytic activities. The core-shell catalysts showed high stability during 48h thermal-reforming.
