    The nucleation crystallography of CrFeNb particle on Ni grain is studied using Edge-to-Edge Matching model. Three orientation relationships are predicted to indicate a semi-coherent interface. A relaxation of some atoms may be necessary to minimize the nucleation interface energy. IN718 superalloy is used to validate the grain refinement effect.

    Honeycombs with zero Poisson's ratio (ZPR) are increasingly used in many important fields because of their unusual properties. A novel ZPR honeycomb is proposed by embedding a rib into every cell of the existing ZPR configuration, semi re-entrant honeycomb (SRH). The new proposed ZPR honeycomb exhibits superior specific stiffness and shows flexible in mechanical properties tailoring. Given these benefits, it may be promising in some applications.

  4. ZnO Coated Anodic 1D TiO2 Nanotube Layers: Efficient Photo-Electrochemical and Gas Sensing Heterojunction

    Ultrathin and homogeneous ZnO coatings within high aspect ratio TiO2 nanotubular structure are demonstrated. ALD ZnO coatings within high surface area TiO2 nanotubes layer form a heterojunction with excellent photoelectrochemical activity and good ethanol sensing response. These enhancements are contributed by the passivated surface traps on tube wall, increased light absorption, close match of coating thickness, and Debye length.

    Vapor-phase deposition methods allow the synthesis of (in)organic thin films, with high control on the chemical-physical properties and conformality. In this review, the encapsulation strategies of active drug molecules by means of vapor phase deposition processes are reported. The effects of (pre-) treatment and thin film deposition on controlled drug release and morphology are also reviewed, together with future perspectives and ‘smart’ device applications.
