Novel Method for the Electrochemical Synthesis of Nickel-Rich Oxide Nanowires

Thorne S.A., Bhargava Y.V., Mintz T.S., Radmilovic V., Suzuki Y., Devine T.M., University of California-Berkeley, US

Using a novel electrochemical process, functionalized and self-assembled Ni-rich oxide nanowires were grown from an Alloy 600 (Ni – 15.5 a/o Cr, 8a/o Fe) substrate. The formation of the nanowires occurs in a high-temperature (238-288 [...]

IrO2 Nano Structures by Metal Organic Chemical Vapor Deposition

Zhang F., Barrowcliff R., Stecker G., Wang D., Hsu S-T, Sharp Labs of America, Inc., US

This paper will discuss the deposition of IrO2 nano structures using (methycycpentadienyl) (1, 5-cyclooctadiene) iridium as the precursor and using Metal Organic Chemical Vapor Deposition (MOCVD) method with no template. Three different shapes of IrO2 [...]

Wire-Streaming Processors on 2-D Nanowire Fabrics

Wang T., Ben-Naser M., Guo Y., Andras Moritz C., University of Massachusetts at Amherst, US

In this paper, we describe our initial architectural designs based on nanowires (NWs). We call our initial integrated circuit systems Wire-Streaming Processors (WISP) because in these designs, in order to preserve the density advantages of [...]

Electronic Structure and Transport in Biological Inorganic Hybrid Materials

Pandey R.R., Bruque N., Lake R.K., University of California Riverside, US

Chemical and biological hybrid organic-inorganic nanotechnology holds the promise to provide new capabilities for manufacturing functional nanosystems for a wide range of applications in engineering and biotechnology. We report fundamental studies used to model bio/inorganic [...]

Theory and Experiments on Periodic Lattice Distortions that Explain 1D Conductivity along the CuO2 Plane Ab And A-B Diagonals in YBa2Cu3O7 (YBCO) 50 nm Film with a 24 DEG Grain Boundary (Gb)

Sahibudeen H.S., Navacerrada M.A., Acrivos J.V., San Jose State University, US

Self consistent field (SCF) calculations carried out at San José State University (using MOLECOLE Linux codes) for a nano-particle of 18 molecules of T’-Nd2CuO4 explain the dxy symmetry for preferred superconductivity in the ab plane. [...]

Nano-scale Material by Design

Bleau D., Eisenbraun E., Raynolds J., US Army RDECOM ARDEC AETC, WS&T Benet Laboratories, US

This research is aimed at developing a fundamental understanding of how atomic scale processing and nano-scale film performance characteristics can be predictably correlated by the use of kinetic Monte Carlo simulation of PA-CVD. Our modeling [...]

Elastic Network Model of Polymer Nanocomposites

Jang Y., Nair S., Kim M.K., University of Massachusetts Amherst, US

We present a novel simulation technique for modeling the nano and micro scale behaviors of plastic flow and fracture around crack tips of polymer nanocomposites. A coarse-grained elastic network model (ENM) simply represents the interations [...]

Numerical Analysis of the Effect of Diffusion and Creep Flow on Cavity Growth at the Nano-scale Level

Brust F.W., Oh J., Battelle Memorial Institute, US

At high temperature, cavity initiation and cavity growth are important phenomena in understanding the failure mechanism and in predicting the lifetime of various parts in service in the area of power plants, aerospace applications, among [...]

Computer Simulation of Nanoparticle Sintering

Koparde V.N., Cummings P.T., Vanderbilt University, US

Nanoparticles have been the area of active research in recent years as they have novel and unique properties, which distinguish them from the bulk phase. Given the difficulties associated with experimental analysis at the nanoscale, [...]

Atomistic Simulations in Nanostructures Composed of Tens of Millions of Atoms: Importance of long-range Strain Effects in Quantum Dots

Korkusinski M., Klimeck G., Xu H., Lee S., Goasguen S., Saied F., Purdue University, US

Realistic calculations of propertioes of nanostructures begin with the determination of equilibrium positions of constituent atoms. The nanoelectronic modeling tool NEMO-3D determines these positions by minimizing the total elastic energy. The displacements are further used [...]
