Abstract:An ultrasensitive electrochemical method for simultaneous determination of lead and cadmium was first developed using the novel bismuth-Nafion-medical stone doped disposable electrode (an improved wax-impregnated graphite electrode). Through the synergistic sensitization effect of the resulting composite material, the disposable electrode showed remarkable electrochemical responses to lead and cadmium. The oxidation of the two metals produced two well-defined and separated square wave peaks at about -0.62V for Pb²⁺ and -0.85V for Cd²⁺, respectively. The effects of the amount of medical stone, concentration of Nafion, thickness of bismuth, pH of buffer solution, deposition potential, accumulation time, voltammetric measurement and possible interferences were investigated in detail. Under the optimal conditions, the fabricated electrode exhibited linear ranges from 2.0 to 12.0μgL^-1 with detection limit of 0.07μgL^-1 for lead and 2.0-12.0μgL^-1 with detection limit of 0.47μgL^-1 for cadmium. The assay results of heavy metals in wastewater with the proposed method were in acceptable agreement with the atomic absorption spectroscopy method. © 2011 Elsevier B.V.

Abstract:In this work, thermal behaviors and viscoelasticity of the PPS/epoxy resin mixtures prepared by melt mixing were studied, and the rheology was used as a tool to further explore the relation between chain structures and properties of the mixtures. The results show that the epoxy resin can promotes degradation and branching of the PPS during melt mixing due to its poor thermal stability. The formation of long chain branched and partly crosslinked structures in the mixtures together with the residual decomposed components hence result in broadening of molecular weight distribution in comparison with those of the neat PPS. As a consequence, the mixtures show the viscoelastic behaviors far different from the neat PPS: the presence of crosslinked structure leads to the strong solid-like responses in the small amplitude oscillatory shear (SAOS) flow, and the presence of long chain branched structure to the weak strain overshoots in the large amplitude oscillatory shear (LAOS) flow. Moreover, after quiescent annealing, a strain-scaling transient stress behavior is observed in the mixtures in the reverse flow. © 2011 Published by Elsevier B.V.

Abstract:A novel biosensor is developed based on immobilization of proteins on nanoflake-like SnS2 modified glass carbon electrode (GCE). With glucose oxidase (GOD) as a model, direct electrochemistry of the GOD/nanoflake-like SnS2 is studied. The prepared SnS2 has large surface area and can offer favorable microenvironment for facilitating the electron transfer between protein and electrode surface. The properties of GOD/SnS2 are characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-vis spectroscopy, Fourier transform infrared spectroscopy (FTIR) and cyclic voltammetry (CV), respectively. The immobilized enzyme on nanoflake-like SnS2 retains its native structure and bioactivity and exhibits a surface-controlled, reversible two-proton and two-electron transfer reaction with the apparent electron transfer rate constant (ks) of 3.68s^-1. The proposed biosensor shows fast amperometric response (8s) to glucose with a wide linear range from 2.5×10^-5M to 1.1×10^-3M, a low detection limit of 1.0×10^-5M at signal-to-noise of 3 and good sensitivity (7.6±0.5mAM^-1cm^-2). The resulting biosensor has acceptable operational stability, good reproducibility and excellent selectivity and can be successfully applied in the reagentless glucose sensing at -0.45V. It should be worthwhile noting that it opens a new avenue for fabricating excellent electrochemical biosensor. © 2011 Elsevier B.V.

Abstract:A novel method of dynamic hand gesture recognition based on Speeded Up Robust Features (SURF) tracking is proposed. The main characteristic is that the dominant movement direction of matched SURF points in adjacent frames is used to help describing a hand trajectory without detecting and segmenting the hand region. The dynamic hand gesture is then modeled by a series of trajectory direction data streams after time warping. Accordingly, the data stream clustering method based on correlation analysis is developed to recognize a dynamic hand gesture and to speed up calculation. The proposed algorithm is tested on 26 alphabetical hand gestures and yields a satisfactory recognition rate which is 87.1% on the training set and 84.6% on the testing set. © 2011 IEEE.

Abstract:The performance of two types of Chinese screw nails in connections between sheathing and wood frame was assessed using ASTM-F1575-03. Specimens were tested in groups of 10, and both parallel-to-grain and perpendicular-to-grain specimens were tested in the case of ASTMF1676-03. It was found that the type of nail had little effect on the performance of nail joints. Finally a modified model suitable to domestic nails in two directions was established on the basis of Foschi's exponential model. The model provides useful data on the performance of sheathing-tolumber connections. © (2011) Trans Tech Publications, Switzerland.

Abstract:Traditional cold extrusion process of internal thread is only fit for processing low-intensity and high plasticity metals such as non-ferrous metals and low-carbon steel. But the internal thread of the key parts such as airplane and high speed train is processed with high-strength steel. During cold extruding high-strength steel internal thread, the effects of lubricant, workpiece bottom hole diameter, extrusion speed and extrusion times on wear and fracture of the tap and manufacturing quality of the internal thread are great. The process of cold extrusion of Q460 high-strength steel internal thread is studied through experiments. The effects of lubricant, workpiece bottom hole diameter, extrusion speed and extrusion times on extrusion torque and extrusion temperature is analyzed. And the ideal internal thread is obtained through optimizing technological parameters. It provides a new basis for improving the surface quality and the fatigue property of internal thread. The test results show that Q460 high-strength steel internal thread is better formed by cold extrusion through one-step forming technology. The fluidic thin film lubricant whose viscosity number is between 10 and 12 is selected. The best range of workpiece bottom hole diameter is between 21.20 mm and 21.30 mm. And the generally selected extrusion speed is between 30 and 60 mm · min^-1. ©2011 Journal of Mechanical Engineering.

Abstract:We proposed an idea for overcoming the difficulties met by the application of colloidal photonic crystal in flat-panel displays, such as overcoming the viewing angle dependence, displaying a complicated image, and, how to control the brightness and saturation of each pixel. In our strategy, nanospheres were firstly self-assembled into uniform spherical units, and then the colloidal crystal units were patterned as pixels. This method was favorable to realize the fabrication of display device in a large scale, with controllable uniformity and easily pattern designing. The problem that display colors varies with the observation angle can probably be adequately corrected through the homogeneity derived from the spherical symmetry of the colloidal crystals. Nematic liquid crystals were infiltrated into the voids of the inverse opaline colloidal crystal unit, and the saturation of the pixels can be controlled by utilizing the field response feature of the liquid crystals. © 2011 Elsevier B.V.
