Abstract:SiO2 aerogels, the lightest solid material have attracted much attention recently. However, it is difficult to be used in practical applications due to its fragility. A facile one step polymerincorporation sol-gel process, together with a surface modification and a normal temperature drying process, was developed to prepare silica-fiber composite aerogels. Four fibers (polyester fiber, polypropylene fiber, lignin fiber, polycrylonitrile fiber) were selected to enhance the intensity of silica aerogels, respectively. The obtained samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) specific surface area. Results showed that samples have a plenty of hydrophobic methyl group attached to their surface. The continuous network structure composed of silica aerogels of high purity are non-crystallized, porous, surface areas from 800 to 980 m<sup>2</ sup>/g and light weight nano-materials. Adsorption experiment of the above samples over organic solution (benzene, toluene) was tested. The composite aerogels absorbed the organic liquids by nearly 6-8 times its own mass, showing potential application in organic absorption. © (2011) Trans Tech Publications.

Abstract:Using Y2O3, Mn(CH3COO)2· 4H2O as raw materials and glacial acetic acid as solvents, YMn xFe1-xO3 precursors (x= 0, 0.05, 0.1, 0.3, 0.5) have been prepared under 80°C water bath conditions. Perovskite YMn xFe1-xO3 samples were achieved after calcination over 900 °C for 4 h. Structure of the samples was characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Ultraviolet obvious diffuse reflection(UV-vis DRS), and Field-emission scanning electron microscopy (FESEM). Photocatalytic activity of the samples was also investigated. Results showed that all the samples with stable perovskite structure had high light absorption in visible-light region, suggesting good visible light harvesting. SEM image showed that the samples were sponge-like and porous agglomerates. Photodecoloration activity of 100 mL Rhodamine B (10 mg/L) was 16∼56 % under illumination for 150 min. Oxygen vacancies of the perovskite may explain the high activity of x = 0.1 sample. © (2011) Trans Tech Publications.

Abstract:A systematic study on internal control of enterprises was carried out. Selected enterprises in Jiangsu Province were studied. Many companies are still in the initial stage of their internal control management, lacking of scientific and modern management. In order to meet the requirements of rapid business development, companies need a qualitative leap of management. Enterprises depends on not only the reformation of the external system, but also the strengthen of the internal control management, by means of scientific methods and management control which can enhance the quality of enterprises. In this way, the internal control fragment of enterprises should be builded up. The internal control environment should be created. The construction of risk evaluation and internal control supervision have to be reinforced. Good control activity and reliable message delivery system ought to be set up and executed. ©2011 IEEE.

Abstract:The tooth surface geometry of involute arch cylindrical gears is analyzed, a new original processing method for the gear named "tooth surface bi-directional envelop machining" is proposed. By using this method, convex tooth surface and concave tooth surface are machined separately with conical rotating cutterhead. In circumferential direction the involute profile is guaranteed by generating method, while in axial direction cambered surface of involute arch cylindrical gear is enveloping cut by the conical cutting edge of the rotating conical cutterhead. By this method, involute arch cylindrical gear can be machined effectively. With superior performance on transmission, the conception of arch cylindrical gear has proposed for a long time, but the application has not developed well, due to the ideal processing method for the gear that has not been resolved.^[1][2] In this paper, the geometry of involute arch cylindrical gears' tooth surface is analyzed, and a new original processing method of involute arch cylindrical gear named "tooth surface bi-directional envelop machining" method is proposed. By this method, involute arch cylindrical gear can be machined effectively. © (2011) Trans Tech Publications.

Abstract:Uniform poly(2-aminothiophenol) nanofibers embedded with highly dispersed gold nanoparticles have been fabricated through a facile templateless one-step method. The diameter of composite nanofibers can be controlled in the range of 200-80 nm by simply tuning the speed of mechanical stirring during materials synthesis. Results from our work will provide insight into the shape-controlled synthesis of other nanomaterials by simply introducing mechanical agitation. Removal of gold nanoparticles in composite nanofibers leads to polymer nanotubes with continuous or incontinuous nanocavities depending on mechanical stirring speeds. Furthermore, morphology-dependent catalytic performances of such composites are also investigated. © 2011 American Chemical Society.
