    In the paper, the nickel silicide phase forming the Schottky junction in a silicon nanowire device is identified and characterized using high resolution TEM and EDX line scan. The sample was prepared using a lift-out process in FIB and corresponding low accelerating voltage ion milling. The EDX line scan data is provides a comprehensive idea about the structure of the Schottky junction, which is essential for the engineering and theoretical modeling of the said junction.

  2. Carbon Fiber/Carbon Nanotube Buckypaper Interply Hybrid Composites: Manufacturing Process and Tensile Properties

    Shaokai Wang, Rebekah Downes, Charles Young, David Haldane, Ayou Hao, Richard Liang, Ben Wang, Chuck Zhang and Rob Maskell

    Carbon nanotube sheet was successfully integrated into carbon fiber composites to create hybrid multifunctional structural composite materials. In this study, nano/micro dual-scale resin flow characteristics and quality control in the autoclave process of manufacturing hybrid composite laminates were investigated. This hybrid composites had competitive strength and modulus, and resulted in dramatic improvements in both in-plane and through-thickness electrical conductivities.

    High Pressure Torsion (HPT) technique is a promising and efficient process for consolidating metal powders by imposing severe shear deformation and high hydrostatic pressure to the samples. Iron powder is compacted successfully into solid disk by HPT at room temperature. The homogeneity of shear strain across the thickness of the disk displays a gradient distribution. The strain gradient leads to the formation of three regions throughout the thickness of the dsisk: Region U, that is Undeformed in torsion (top part – in contact with the fixed punch), Region T, Transition or intermediate region where the shear strain is increasing, and Region S, which is Severely deformed (bottom part in contact with the rotating die) which is uniformly and heavily sheared. The microstructure and Vickers hardness in the three regions show a non-uniform distribution, corresponding to the strain gradient.

  4. Monodisperse Polystyrene Foams via Microfluidics – A Novel Templating Route

    Aggeliki Quell, Jonas Elsing, Wiebke Drenckhan and Cosima Stubenrauch

    Article first published online: 19 MAR 2015 | DOI: 10.1002/adem.201500040

    Microfluidic techniques can be used to generate highly monodisperse polystyrene foams with periodic pore organization. For this purpose, monodisperse foamed emulsions and emulsions, respectively, are to be used as templates. The polymerization of the templates leads to tailor-made polystyrene foams with controllable pore size, pore size distribution, and connectivity.

  5. Shape Recovery Kinetics in Vascularized 3D-Printed Polymeric Actuators

    Aditya Balasubramanian and Christopher J. Bettinger

    Article first published online: 19 MAR 2015 | DOI: 10.1002/adem.201500091

    The shape recovery kinetics of vascularized 3D-printed thermo-responsive shape memory polymeric actuators are measured and compared with predictive models. Experimental and modeled recovery kinetics are in close agreement. A generalizable framework based on predictive models to assess the intrinsic property of SMP that governs the response actuation rate is presented.
