The present paper is to provide our study results on adsorption-desorption features of thallium in different burden soils through a batch test and investigation. To proceed with our research, we have investigated the adsorption-desorption behaviors of thallium in the soils with different pollutants of iron sulfide was…
Electroless copper pre-plating on ABS was made using glyoxal as reductant instead of traditional formaldehyde,and then copper eletroplating was made using basic cupric carbonate as main salt.Effects of the bath Composition and pH on copper coating were discussed in this paper.The optimized technological condition was:…
The α-Al2O3/Al4.59Si1.41O9.7/Al2TiO5 multiphase material with high performance was prepared by reaction sintering. The influence of different formulas on the structures and properties of multiphase material was investigated to determine the optimal formula. Crystalline structure and cell parameters of sintered samples…
The basic mechanical properties of E-glass fiber reinforced composites were achieved through tensile test to provide reference data for the material model and numerical simulation.Composite elastic constitutive equation was obtained through orthotropic constitutive material by derivation of elasticity and the numerica…
Ammonia was added to the ion-exchange solution to adjust the pH in the preparation of CuNaY catalyst by ion-exchange of NaY zeolite with Cu2+ aqueous solution,and then the ion-exchanged CuNaY was activated by high temperature calcinations.The effect of anion type in the Cu2+ aqueous solution on the ionexchange process…
The effect of the operation parameters,such as reaction temperature,feedgas flow and volume ratio of hydrogen to paraffins,on the performance of Pt-Sn-K / γ-Al2O3 catalysts for the dehydrogenation of isobutane was investigated by the methods of orthogonal and the single factor experiments. The results showed that the…

The effect of dyeing and printing process on properties of high tenacity flame-retardant vinylon blended fabric is analyzed.One-face-one-back shearing process,moderate pretreatment process,high-temperature steaming process and pre-shrinking process with rubber blanket is helpful to the strength,handle and color fastne…
Reaction of Ni(CH3COO)2·4H2O with NaH2B(pz)2 in methanol at room temperature gaves a complex of [Ni(H2B(pz)2)2](pz = pyrazolyl).The complex was characterized by elemental analysis,IR,and X-ray diffraction.Here,we report the kinetics of thermal decomposition of the complex under non-isothermal condition.The kinetic fun…
The sand inclusion causes on the big plane of rear axle box castings were discussed in this paper. On the basis of force analysis, the bending fracture process of sand mould surface layers is studied; it is indicated that the vertical compressive stress is the cause for early bending of sand mould surface layers. The…
The structures and nonlinear optical(NLO) properties of a series of superalkali compounds,Al 7 X0 /-(X = F,Cl,Br,I) were investigated by the means of density functional theory(DFT) calculations.The results indicate that the halogens have little influence on the geometry of the compounds.The present results indicate th…
Ag/AgX photocatalysts,as the new photocatalysts,exhibited high photocatalytic activity for the degradation of organic pollutants under visible light irradiation due to the obvious surface plasmon resonance(SPR) effect in the visible light region.In this paper,the structure,mechanism,preparation methods and morphology…
A hydrogen peroxide biosensor with high performance was obtained by co-immobilizing horseradish peroxidase(HRP)and the Pt/poly(3,4-ethylenedioxythiophene)(PEDOT)/MWCNTs composite with Nafion,which was prepared through improved one-step chemical synthesis route with multi-walled carbon nanotubes(MWCNTs)as the carriers.…
