Numerical Modelling of Experimentally Fabricated Inas/Gaas Quantum Rings

Filikhin I., Deyneka E., Vlahovic B., North Carolina Central University, US

In the presented work we apply a single subband model for InAs/GaAs QD(QR), where the electron effective mass depends on the confinement energy by the Kane formula. The geometrical parameters of the model are based [...]

Mobility of Electrons in Rectangular Si Nanowires

Ramayya E., Vasileska D., Goodnick S.M., Knezevic I., Arizona State University, US

We investigate two issues in this paper. First, we examine the role of interface-traps on the device drain current in an SOI nanowire MOSFET. Afterwords, we investigate the role of the interface-roughness on the low-field [...]

Tracking the Formation of a Break Junction Formed by Electromigration using Transmission Electron Microscopy

Dong J., Parviz B.A., University of Washington, US

Break junctions formed by electromigration have been extensively used in the molecular electronics and electrical characterization of atomic or molecular clusters and biological molecules such as deoxyribonucleic acid (DNA)1. However, to obtain a controllable gap [...]

Interface-Property Relationships in Hybrid Nanocomposites from Near Net-Shape Manufacturing

Mitchell B.S., Tulane University, US

Near Net-Shape Manufacturing is a two-step materials processing technique, in which nanoparticles are formed via mechanical attrition, from which nanocomposites are formed by consolidation and densification using Hot Isostatic Pressing (HIP). The technique is general [...]

Layered Oxide Polymer Nanocomposites: Synthesis, Characterization, and Strategies for Achieving Enhanced Barrier Property

Hansen T.J., Barber P., Ma J., Ploehn H.J., zur Loye H.-C., University of South Carolina, US

Our research goal is to enhance the gas barrier of polymer nanocomposites using exfoliated layered materials. We have synthesized various layered oxides, ranging from layered polysilicates to perovskites, and explored novel modification techniques. Polymer films [...]

Multifunctional Nanocomposites Made of Polypropylene Reinforced with Exfoliated Graphite Nanoplatelets (xGnP)

Kalaitzidou K., Fukushima H., Drzal L.T., Michigan State University, US

Polypropylene is one of the most widely used polymers. It is an attractive material because of its combination of mechanical properties, ease of processing and low cost. This research explores modification of polypropylene through addition [...]

Protein can act as unique template to assemble gold nanoparticles in a linear fashion

Bhattacharya R., Patra C.R., Wang S., Lu L., Yaszemski M.J., Mukhopadhyay D., Mukherjee P., Mayo Clinic, US

Nanoparticles of metals possess unique chemical, electronic, optical and magnetic properties from their bulk counterpart because of the quantum size effects. The spatial orientation and arrangement of nanoparticles is important in the realization of technologically [...]

Formation and Coatings of Fine Particles in Jets of Supercritical Fluids

Gokhale A., Shen Y., Khusid B., Dave R., Pfeffer R., New Jersey Institute of Technology, US

Recently published studies of the formation of polymer particles in supercritical carbon dioxide are limited to the use of good organic solvents or their mixtures and relatively wide nozzles. In contrast, we use the new [...]

Paclitaxel Conjugate Block Copolymer Nanoparticle Formation by Flash NanoPrecipitation

Saad W.S., Mayer L., Princeton University, US

Nanoparticle formulations of drugs, printing inks, sun screens, and other hydrophobic organic compounds have distinct advantages in bioavailability, color intensity, and aesthetics. Common requirements of these applications are control of particle size and surface functionality. [...]

Electrochemical Synthesis of Polyaniline Nanoparticles and Nanofibers

Xavier M.G., Leite E.R., Leite F.L., Leite E.R., Leite F.L., Venancio E.C., MacDiarmid A.G., Mattoso L.H.C., ARS-USDA, US

It is known that the properties of polymers produced by the electrodeposition of aniline is strongly dependent on the experimental conditions used. In these electrochemical methods two main steps can occur, the (1) nucleation process [...]
