Conductivity and contact resistance of 100 nm and 250 nm diameter platinum (Pt) nanowires (NWs) are investigated computationally and experimentally. Finite element method based full-wave modeling and circuit simulations are used in conjunction with

Accelerator Surface Phase Associated with Superconformal Cu Electrodeposition

March 5, 2010
Author(s)
Thomas P. Moffat, Liang Yueh Ou Yang
Superconformal film growth is a key process in state-of-the-art Cu metallization of electronic devices. Superfilling of recessed surface features results from competition between electrolyte additives that accelerate or inhibit Cu electroplating. In situ

This is the final report of a research project entitled Smoke Aerosol Measurements Experiment (SAME). Smoke and/or fire detection in the spacecraft is crucial to the success of future long term space travel. It has been realized that the gravity force

Low-loss superconducting resonant circuits using vacuum-gap -based microwave components

March 4, 2010
Author(s)
Katarina Cicak, Dale Li, Joshua Strong, Michael S. Allman, Fabio Altomare, Adam J. Sirois, Jed D. Whittaker, Raymond W. Simmonds
We have produced high quality resonant microwave circuits through developing a vacuum-gap technology for fabricating lumped-element capacitive and inductive components. We use micromachining to eliminate amorphous dielectric materials leaving vacuum in

Diffusion-controlled reference material for VOC emissions testing: proof of concept

March 3, 2010
Author(s)
Steve Cox, Zhe Liu, John Little, Cynthia H. Reed, Steven J. Nabinger, Andrew K. Persily
Because of concerns about indoor air quality, there is growing awareness of the need to reduce the rate at which indoor materials and products emit volatile organic compounds (VOCs). To meet consumer demand for low emitting products, manufacturers are

Energy dissipation of highly charged ions on Al oxide films

March 3, 2010
Author(s)
Joshua M. Pomeroy, Russell Lake, C E. Sosolik
Slow highly charged ions carry a large amount of potential energy that can be dissipated within femtoseconds upon interaction with a surface. HCI-insulator collisions result in high sputter yields and surface nano-feature creation due to strong coupling

Matrix Relaxation After Fracture In A Toughened Epoxy

March 3, 2010
Author(s)
Aaron M. Forster, Aurelien Blond, Donald L. Hunston
The inclusion of phase-separated rubber particles in a brittle thermoset matrix has been shown to increase the Mode I fracture energies for a wide range of model and commercial adhesives. Our recent efforts combine these two approaches by comparing the

Measurement Challenges in Achieving Energy Monitoring Systems in Buildings

March 3, 2010
Author(s)
William M. Healy
The benefits of energy conserving approaches in buildings are often not apparent to building occupants because of the insufficient feedback provided regarding energy consumption. A review of the literature suggests that energy feedback devices can provide

Normal-state conductance used to probe superconducting tunnel junctions for quantum computing

March 3, 2010
Author(s)
David P. Pappas, Jeffrey S. Kline, Seongshik Ohy, Carlos Chapraro, Richard Bavier, Yong Kim, Eunyoung Kim
Here we report normal-state conductance measurements of three different types of superconducting tunnel junctions that are being used or proposed for quantum computing applications: p-Al/a-AlO/p-Al, e-Re/e-AlO/p-Al, and e-V/e-MgO/p-V, where p stands for

Water based Polyurethane Graphene Oxide Nanocomposites

March 3, 2010
Author(s)
Coralie Bernard, Tinh Nguyen, Bastien T. Pellegrin, Mat Celina, Alexander J. Shapiro, Deborah Jacobs, Kar T. Tan, Sungjin Park, R. S. Ruoff, Joannie W. Chin
Graphene oxides are potentially a new class of nanomaterial to enhance multifunctional properties of polymers because of their remarkable thermal conductivity, mechanical strength, and more importantly, low cost. The graphene oxides, produced by

Erratum: Scintillation time dependence and pulse shape discrimination in liquid argon

March 2, 2010
Author(s)
W. H. Lippincott, Kevin Coakley, D. Gastler, A. Hime, E. Kearns, D. N. McKinsey, J. A. Nikkel, L.C. Stonehill
We have found an error in the code used to perform the multibin method analysis of Sec. III C in which events were compared to a template trace calculated from the wrong photoelectron bin (the index l in Eqs. (14) and (15) did not match the observed signal

Scintillation time dependence and pulse shape discrimination in liquid argon

March 2, 2010
Author(s)
W. H. Lippincott, Kevin Coakley, D. Gastler, A. Hime, E. Kearns, D. N. McKinsey, J. A. Nikkel, L. C. Stonehill
Using a single-phase liquid argon detector with a signal yield of 4.85 photoelectrons per keV of electronic-equivalent recoil energy (keVee), we measure the scintillation time dependence of both electronic and nuclear recoils in liquid argon down to 5

The Nanomechanical Properties of Thin Film of Type I Collagen Fibrils

March 2, 2010
Author(s)
Koo-Hyun Chung, Kiran Bhadriraju, Tighe Spurlin, Robert F. Cook, Anne L. Plant
Cells sense and respond to the mechanical properties of the substrate to which they adhere. Matrices composed of collagen have been an important experimental system to study cell responses to the stiffness of the extracellular matrix. We had previously

Wind Driven Fire Research: Hazard and Tactics

March 2, 2010
Author(s)
Daniel M. Madrzykowski, Stephen Kerber
Fires in high-rise buildings create unique safety challenges for buillding occupants and fire fighters. Smoke and heat spreading through the corridors and the stairs of a building during a fire can limit building occupants' ability to escape and can limit
