    Notes: By means of solid-state reactions method, ZnSnO3 nanoparticles were prepared in the reactions of ZnCl2 and SnCl4·5H2O with KOH in the presence of added KCl crystal, and were assembled into 3-D aggregates with tetragonal-like shape in the size range of 20-200 nm. The products were characterized by powder X-ray diffraction (XRD), and the microstructures of the samples were investigated by transmission electron microscope (TEM), selected area electron diffraction (SAED) and high-resolution transmission electron microscope (HRTEM) in detail. Probable mechanisms for the formation of such tetragonal-like shape of ZnSnO3 3-D aggregates are proposed

    Notes: A model based on the cellular automaton (CA) technique for the simulation ofsolidification microstructure has been developed. An improved solid fraction calculating method isused, in which the solid fraction of the interface unit is calculated by temperature compensationmethod combined with local equilibrium phase diagram. And then, a quadratic equation of solidfraction can be calculated according to the local temperature, solute concentration and curvature.The method avoids the assumption of the position and shape of solid/liquid interface. By using thismodel on A356 aluminium alloy, a dendrite growth process is simulated. The model can predict thefinal microstructure both grain size and grain morphology. It also predicts the Si concentrationdistribution in both solid and liquid phases

    Notes: Purpose - Aim for efficient motion planning of industrial robot with high degree of freedoms in both static and dynamic environments. Design/methodology/approach - A multi-agent based general path planner for serial manipulator is proposed in this work. A hierarchical structure developed based on fuzzy reasoning is employed in the planner. The high level in the hierarchical structure is designed to dynamically assign each link an appropriate behaviour and the low level is designed to determine the joint speed according to the behaviours assigned by the high level. Findings - Combination of multi-agent concept and fuzzy reasoning approach can obtain both flexibility and efficiency in motion planning of serial manipulator with high degree of freedoms. Research limitations/implications - Multiple local minima problem occurred in complex manipulation scenario has not yet been considered. Practical implications - Applicable for real time motion planning of serial industrial robots with high degrees of freedom in 3D space. Originality/value - In this research work, we make use of the of multi-agent plus fuzzy logic concept to design a novel manipulator motion path planner, in particular, we introduce a novel mechanism into the fuzzy logic algorithm with the "back-tracking" ability to avoid the local minima problem.The proposed motion planner has advantages on low computational cost, the suitability for real time path planning in 3D space and the capability to escape simple local minima.

    Growth of YBaCuO thin films on random and (100) aligned ZrO2 substrates (1989)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 55 (1989), S. 1792-1794

    Notes: The growth quality of thin, superconducting YBaCuO films has been compared on random and (100) oriented yttrium-stabilized zirconia substrates using x-ray diffraction and ion channeling experiments. Superior growth is observed on (100) substrates with narrow mosaic distributions (0.4°) and a minimum yield value of 10% in the channeling experiment. The lattice matching required for epitaxial growth is achieved by azimuthal adjustment of the film plane with respect to the substrate. The superior growth is reflected in the film properties like the critical current density yielding values of 2×106 A/cm2 at 77 K.

    Growth characterization of YBa2Cu3O7−x thin films on (100) MgO (1989)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 55 (1989), S. 310-312 
    Details
    ISSN: 1077-3118
    Source: AIP Digital Archive
    Topics: Physics
    Notes: The growth features of YBa2Cu3O7−x thin films on (100) MgO substrates were studied by He ion channeling and x-ray diffraction measurements. A minimum yield value of 7% at 2 MeV He ion energy and a standard deviation of the crystallite misorientation of only 0.1° show that epitaxial growth (c-axis oriented) is achieved despite a large lattice mismatch of about 9% between the film and the substrate. Detailed studies of the energy dependence of the dechanneling yield at the film-substrate interface for films of different thickness reveal the presence of dislocations probably formed by strain relief in the initial state of growth. Stacking faults appear as the main defect structure in the bulk of the films.

    Preparation and superconducting properties of ultrathin YBa2Cu3O7−x films (1989)
    Woodbury, NY : American Institute of Physics (AIP)

    Topics: Physics
    Notes: Ultrathin films of YBa2Cu3O7−x with thicknesses down to 2 nm were grown on(100)SrTiO3 and (100)MgO by inverted cylindrical magnetron sputtering. Metallic behavior and zero resistance temperatures above 4.2 K were obtained in 3-nm-thick films on SrTiO3. Thinner films revealed temperature-activated conductivity and only partial transitions to superconductivity due to inhomogeneities in the film morphology. On MgO, the critical film thickness leading to deteriorations of the transport properties was 6 nm. An analysis of the fluctuation-enhanced conductivity near Tc in terms of the Aslamazov–Larkin theory [Phys. Lett. A 26, 238 (1968)] revealed three-dimensional behavior even in the thinnest fully superconducting films.

    Notes: The material removal rate (MRR) model was investigated in abrasive jet precisionfinishing (AJPF) with wheel as restraint. When abrasive wore and workpiece surface micro-protrusion removed, the size ratio for characteristic particle size to minimum film thickness gradually diminishing, the abrasive machining from two-body lapping to three-body polishing transition in AJPF with grinding wheel as restraint. In the study, the material removal rate model was established according to machining mechanisms and machining modes from two-body to three-body process transition condition, and active number of particles in grinding zone were calculated and simulated. Experiments were performed in the plane grinder for material removalmechanism and academic models verification. It can be observed from experimental results that the surface morphology change dramatically to a grooved or micro-machined surface with all the grooves aligned in the sliding direction in two-body lapping mode. On the other hand, the surface is very different, consists of a random machining pits with very little sign of any directionality to the deformation in the three-body machining mode. Furthermore, the material removal rate model wasfound to give a good description of the experimental results
