Abstract:Monodisperse and single-phase cerium oxide nanopowders were synthesized by mixed solvothermal route, Ce(NO3)3·6H2O as raw materials, poly (vinylpyrrolidone) (PVP) as stable agent. The cerium oxide nanopowders could be controlled from 50 to 60 nm by adjusting the ratio between ethanol absolute and water at 160 °C. With methanol instead of ethanol absolute, the reaction temperature could be lowered to 130 °C. © 2010 The Chinese Society of Rare Earths.

Abstract:Mesoporous silica materials with well-ordered hexagonal structure were synthesized under acidic conditions. The influences of crystallization conditions, aging conditions, acid sources HX and acid/ tetraethyl orthosilicate ratio on the order degree and the morphology have been discussed. The increase of crystallization temperature or crystallization time was beneficial for the condensation of silica species, but had no effect on improving the order degree of mesoporous silica. The order degree of mesoporous materials using various acid sources HX under the same acid concentration swas as follows: HNO 3>HBr> H2SO4>HCl which differed from that in the Hofmeister series; the sulfate anions 24 SO2-4 can play a supporting role on pore structure in the form of space occupation, leading to forming more ordered products than in HCl. Besides, the NO 3¯ and Br¯ions showed contrary effect on the growth of micelles, the bigger the pore wall thickness we obtained, the less HBr or the more HNO3 we used.

Abstract:The computational fluid dynamics (CFD) method is used to investigate the three-dimensional(3D) flow fields in a postpositional bulb tubular pump. In the numerical modeling, RNG k-Ε turbulence model and SIMPLE algorism are employed. The velocity distribution and pressure of vertical plane at BEP are analyzed, as well as the velocity of impeller outlet, guide-vane outlet and the tail of the bulb. The focus is on the static pressure distribution of blade pressure surface and suction surface as well as the relative velocity distribution near the airfoil cross-sections under different conditions (the designed condition, large and small flow rates conditions). The hydraulic losses of various components of tubular pump are also calculated, and it is found that the guide vane and bulb unit occupy major share in hydraulic losses. The comparison between the mathematical model calculation result and the model-tested pump performance data shows that the calculation result agrees well with the test data in nearby the high efficiency area; however, deviation exists between them under large flow and small flow working conditions. Using CFD method to simulate the internal flow field of tubular pump can provide the basis for further design optimization of the tubular pump. © 2010 Journal of Machanical Engineering.

Abstract:By using semi-analytical method, elastic stability of a simply supported FGM sandwich circular cylindrical shell under torsion loading was studied. The inner and outer layers of the shell are comprised of the same homogeneous and isotropic material, and the middle layer is made of an isotropic functionally graded material whose properties varies continuously in the thickness direction from the inner layer to the outer layer, and keeps continuation in the material properties of the interface. Firstly, based on the Flu¨gge thin shell theory, the governing equations for static buckling of the structure in terms of displacements were formulated. Secondly, by introducing the displacements in terms of trigonometric functions that identically satisfy the boundary conditions, an eigenvalue problem for linear algebraic equations including the torsion force parameter is obtained. Finally, critical buckling load characterizing the features of instability of the structure were obtained by numerical method. The numerical results show that the buckling load decreases with an increases in the radius to thickness ratio, and increases with an increase in the average value of Young's modulus of the FGM middle layer.

Abstract:A novel glucose biosensor was achieved by casting the biocomposite on the surface of platinum disk electrode via the cross-linking step by glutaraldehyde, with the laboratory-prepared bismuth oxide nanoparticles as enzyme immobilization matrix. The modified electrode has been characterized by scanning electron microscopy (SEM), infrared spectroscopy (IR) and electrochemical impedance (EIS) etc. SEM shows that the prepared nano-bismuth oxide is composed by two-dimensional nano-bismuth oxide sheet and one-dimensional nano-rod. The nano-bismuth oxide sheet thickness is about 80 to 110 nm with sub-micron-micron-level horizontal dimensions, and the diameter of bismuth oxide nanorods is about 40 to 50 nm. Experimental results show that the optimal conditions to fabricate biosensor are: GOD and BiOx mass ratio of 2:1, enzyme immobilized amount of 30 μg. The pH and the detection potential effects were also investigated. The biosensor has a wide linear range from 1 × 10-3 to 1.5 mmol/L with detection limit of 0.4 mmol/L (SNR=3) at 0.5 V vs. SCE. The apparent Michaelis constant is 2.88 mmol/L. And the biosensor presents fast response (5 s), good repeatability and excellent long-term stability.

Abstract:Cereal starch granules with high-amylose and resistant starch (RS) always show irregular morphology and special crystalline structure, but their formation during grain development is not yet clear. In our previous studies, we had generated a transgenic rice line (TRS) enriched with amylose and RS, which contained semi-compound starch showing a C-type crystalline structure. In this study, the formation of semi-compound C-type starch granule during TRS endosperm development was carefully investigated with light, scanning electron, and transmission electron microscopes and X-ray powder diffraction. The results showed that the TRS starch subgranules, each with a central hilum, were individually initiated in amyloplast and showed an A-type crystal at the early stage of starch granule development, which was similar to that in its wild type. However, with the endosperm development, the amylose content in TRS endosperm starch increased and the B-type starch crystal was deposited in the periphery of subgranules; then, the adjacent subgranules fused together and finally formed a continuous outer layer band surrounding the entire circumference of the starch granule. Accordingly, a mechanistic model for the formation of semi-compound C-type starch granules is proposed. © 2010 American Chemical Society.

Abstract:Pure nano-Fe3O4 and cobalt-doped nano-Fe 3O4 particles are successfully synthesized by co-precipitation method using tetramethylammonium hydroxide (TMAOH) as alkali. Several key factors that may affect preparation are carefully discussed such as alkali concentration, alkali dosage, reaction temperature, iron salt solution concentration and dispersant agents. Such nano-Fe3O4 particles prepared have good dispersibility and a very narrow size distribution with the average diameter about 38 nm, which are proved to be cubic spinel Fe3O4 crystal by XRD pattern. It is also found that the addition of PEG-4000 surfactant can improve the dispersibility of nanoparticles. In our work, effects of cobalt dopant concentration on magnetic properties of cobalt-doped nano-Fe3O4 are also discussed. The result shows that the coercivity of cobalt-doped nanoparticles changes greatly with the variation of cobalt dopant concentration. The maximum coercivity reaches as high as 1628 Oe, which is very meaningful for preparation of materials with high coercivity. © 2010 World Scientific Publishing Company.
