The Infrared Spectra of BF3+ and BF2OH+ Trapped in Solid Neon

May 20, 2011
Author(s)
Marilyn E. Jacox, Warren E. Thompson
Observations on a Ne:BF3 = 400:1 mixture into which a trace of normal or isotopically enriched water had been introduced, codeposited at 4.3 K with a beam of neon atoms that had been excited in a microwave discharge, demonstrate that a pair of absorptions

Inter-ion Coulomb interactions in a Magneto-Optical Trap Ion Source

May 19, 2011
Author(s)
Jabez J. McClelland, Brenton J. Knuffman, Adam V. Steele
We have investigated the role played by inter-ion Coulomb interactions in a magneto-optical trap ion source (MOTIS). Using a Monte Carlo simulation accounting for all pair-wise ion-ion Coulomb interactions in the source, we have calculated the broadening

Electrical Reliability Testing of Single-Walled Carbon Nanotube Networks

May 18, 2011
Author(s)
Mark C. Strus, Ann C. Chiaramonti Debay, Robert R. Keller, Yung J. Jung, Younglae Kim
We present test methods to investigate the electrical reliability of nanoscale lines of highly-aligned, networked, metallic/semiconducting single-walled carbon nanotubes (SWCNTs) fabricated through a template-based fluidic assembly process. We find that

Hyperbranched Poly(ethylene oxide) Electrolytes for Lithium Ion Batteries

May 17, 2011
Author(s)
Christopher L. Soles, Kirt A. Page, Huagen H. Peng
This work demonstrates the capability of hyper-branched PEO polymers to act as a polyelectrolyte for Li-ion batteries. Hyperbranching has been shown to lead to a 100 fold increase in the ion conductivity below the melting temperature of the PEO

Robust Iris Recognition Baseline for the Grand Challenge

May 17, 2011
Author(s)
Yooyoung Lee, Ross J. Micheals, James J. Filliben, P J. Phillips
Due to its distinctiveness, the human iris is a popular biometric feature used to identity a person with high accuracy. The “Grand Challenge” in iris recognition is to have an effective algorithm for subject verification or identification under a broad

Electronic transport in two dimensional graphene

May 16, 2011
Author(s)
Shaffique Adam, Sankar Das Sarma, Euyheon Hwang, Enrico Rossi
We provide a broad review of fundamental electronic properties of two-dimensional graphene with the emphasis on density and temperature dependent carrier transport in doped or gated graphene structures. A salient feature of our review is a critical

EXPOSING GLAZING ASSEMBLIES TO FIREBRAND SHOWERS

May 16, 2011
Author(s)
Samuel L. Manzello, Sayaka S. Suzuki, Yoshihiko Hayashi
An experimental campaign was undertaken to determine vulnerabilities of glazing assemblies to firebrand bombardment using the NIST Dragon installed in the Building Research Institute’s Fire Research Wind Tunnel Facility (FRWTF). Results of these

Fabrication, characterization and simulation of high performance Si nanowire-based non-volatile memory cells

May 16, 2011
Author(s)
Xiaoxiao Zhu, Qiliang Li, D. E. Ioannou, Xuelei X. Liang, Diefeng Gu, Helmut Baumgart, John E. Bonevich, John S. Suehle, Curt A. Richter
We report the fabrication, characterization and simulation of Si nanowire SONOS-like non- volatile memory with HfO2 charge trapping layers of varying thicknesses. The memory cells, which are fabricated by self-aligning in situ grown Si nanowires, exhibit

Mechanics behind 4-D interferometric measurement of biofilm mediated tooth decay

May 16, 2011
Author(s)
Michael S. Waters, Bin (. Yang, Nancy J. Lin, Sheng Lin-Gibson
Evaluating the efficacy of dental materials to protect human teeth requires the capacity to measure tooth accurately and precisely decay. Current practices for determining tooth decay are destructive, qualitative to lowly quantitative, and/or measure bulk
