    Notes: Ceria nanoparticles supported on aligned carbon nanotubes (CeO2/ACNTs), a noveladsorbent for fluoride from drinking water, were prepared by chemical reaction of CeCl3 withNaOH on aligned carbon nanotube solution and subsequent heat treatment. The best fluorideadsorption effect of CeO2/ACNTs occurs at pH 4.0 ~ 9.0. The largest adsorption capacity ofCeO2/ACNTs reaches 33.7 mg g-1 at an equilibrium fluoride concentration of 18.0 mg l-1 at pH 7.0.The experiment results suggest that CeO2/ACNTs have great potential applications inenvironmental protection

    Notes: In today’s highly volatile global market, design activities become more and more importantin the whole lifecycle of product. The process of different developments should adopt appropriatemodeling approaches at each stage. Different modeling technologies exert a great impact on differentdesign stages. Therefore, modeling design is crucial to achieve success in the process of productdevelopment. This paper presents an integrated modeling of design process for product development.Its objective is to realize concurrent design towards ever-growing demands of market that has alreadyintegrated design process and production activities. It can manage to develop product towards earlydesign activities. Different design stage model relations and activities are presented for productdevelopment. At first, the characteristics of different development stages are analyzed. Theperformances and attributes of product are established through considering component, constraintsand environment. Second, the process of product modeling is described in detail for early design, andthe time interval between the two activities is evaluated for concurrent engineering during the designmodeling. Third, a promising framework is given to describe the process of design. Finally, anapplication example and knowledge are presented to illustrate the process of product development

    Notes: This paper presents a numerical simulation of anti-overturning control of seriallyconnected isolation system using an imagined novel device by combining piezo electric foot and MRtube support. In the vibration isolation of a serially connected electric device which is a real projectand was installed on an overhead frame, overturning was observed as a determinant failure mode. Tocounter for this overturning problem, several additional bolts were used in the isolation layer whichdecreased the isolation effect. This paper further proposed a semi-active solution using a device forproviding anti-overturning moment without increasing the seismic response of the superstructure.This paper presents the idea of the control device set-up and provides a vibration control algorithm, aswell the range of validity of parameters of the plant

    Notes: Al-Cu-Fe quasicrystals powder was used to prepare the thin films on the surface of the A3steel by the means of DMD-450 vacuum evaporation equipment. The thin films with differentcharacterization were obtained through different parameters. The microstructures of the thin filmswere analyzed by Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD). Additionally,the nano-hardness and the modulus of the films are tested by MTS and Neophot micro-hardnessmeter. The results showed that the modulus of the films was about 160GPa. Nano hardness of thefilms was about 7.5 Gpa. The films consisted of CuAl2, AlCu3. The thickness and the micro-hardnessof the films are improved. In same way, with the increase of the electric current, the thickness and thehardness of the films are also improved. Along with increase of the time and the electric current, thewear behavior of the films was improved. To some extent, the microstructure of films contained thequasicrystal phase of Al65Cu20Fe15

    Notes: The present paper investigates the bulk metallic glass formation in Co-based alloy systemswith the guidance of the cluster line and minor-alloying principles. The selected basic ternary Co-B-Sialloy compositions are intersecting points of cluster lines, defined by linking special binary clusters tothe third element. Then these basic ternary alloys are further minor-alloyed with Nb and quaternarybulk metallic glasses are obtained only by 4-5 at. % Nb minor-alloying of the basic compositionCo68.6B25.7Si5.7 that is developed from dense-packed cluster Co8B3. The bulk metallic glasses areexpressed approximately with a unified simple composition formula: (Co8B3)1(Si,Nb)1. In addition, aquantity of Fe substitution for Co further improves the glass-forming abilities

    Notes: Ternary Sm-Al-Co bulk metallic glass formation is investigated with the guidance of acluster line approach which is defined by linking a special cluster composition to the third element inthe ternary phase diagram. Two dense-packed cluster lines Sm6Al3Co2-Co and Sm8Al1Co4-Al areconstructed and they intersect at a good BMG composition Sm50Al25Co25. This composition can alsobe interpreted with a cluster-plus-glue atom model. The characteristic parameters of this optimumBMG are respectively Tg = 579 K, Tx = 640 K, Trg= 0.648, γ = 0.435 and [removed info]E=244 kJ/mol

    Notes: Single-phase nanocrystalline diamond composite is very difficult to sinter because of ahuge amount of oxygen-containing and nitrogen-containing functional groups adsorbed on thesurface of nanocrystalline diamond going against the yielding of diamond-to-diamond bonding. Inthis paper, silicon film was deposited on nanocrystalline diamond by means of atomic layerdeposition (ALD) using silane as precursor, which would promote the sintering of nanocrystallinediamond as the bond. The structure and the morphology of Si-deposited nanocrystalline diamondwere thoroughly studied by X-ray diffraction (XRD), high-resolution electron microscopy (HREM)and Fourier transform infrared (FTIR) spectra. The results confirmed that silicon film grewuniformly on every primary particle and functional groups adsorbed on the surface ofnanocrystalline diamond were removed by this method

    Notes: Nanocrystalline diamond compact possesses not only the advantageous performance of polycrystalline diamond but also the high strength and the high toughness of nano-ceramics. However, single-phase nanocrystalline diamond compact is very difficult to sinter because of a huge amount of oxygen-containing and nitrogen-containing functional groups absorbed on the surface ofnanocrystalline diamond. In this paper, atomic layer deposition (ALD) method has been used to coat nanocrystalline diamond with titanium, which will promote the bonding of nanocrystalline diamond as the bond in polycrystalline diamond. In vacuum, the H2 and TiCl4 reactants were employed alternately in an ABAB… binary reaction sequence to achieve Ti layer, which reacted with diamond matrix and formed TiC in the coating, realizing strong chemical bonding between thecoating and the diamond. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were utilized to study the structure and the morphology of the coating. The results confirmed the formation of titanium carbide at the depositing temperature 500°C. The darker spots and strips observed on nanocrystalline diamond particles by TEM were proved to be TiC and the nucleation and subsequent growth of TiC preferentially occurred in the defects as twin zones and dislocation areas on diamond surfaces

    Notes: B-doped diamond is an excellent grinding material owing to its high hardness, oxidationresistance and chemical inertness as well as low resistance. The recent developments of Borondoped conductive diamond has further increased the scale of diamond applications including themanufacture of electrically conductive grinding wheel or the use as an electrode in EDM. Theunique electrochemical properties also attract the researchers’ attention on the applications ofelectrode, sensor and detectors etc. This paper presents a viable technology that high boron dopeddiamond is synthesized under high pressure and high temperature using B-doped GICs as carbonsources. The synthetic diamond grains with electrically resistivity of 2[removed info]cm are sufficientlyconductive for electrochemistry measurement. Cyclic voltammotry was performed to evaluate theelectrode characteristics of diamond powder. The results shows that B-doped diamond powderelectrode is electrochemically stable in the supporting electrolytes such as 0.1M KCl, 0.5M Na2SO4and 0.1M H2SO4 over a wide potential range. The level of background current is very low. Theelectrode reaction is quasi-reversible in 0.5M Na2SO4 containing the ferricyanide-ferrocyanideredox couple
