Measuring Up to Sustainable Water: Report from the 2010 NIST/Virginia Tech. Water Workshop

September 9, 2010
Author(s)
Lauren F. Greenlee, Jessica D. Torrey, Stephanie A. Hooker, Michael J. Fasolka, Sunil K. Sinha, Marc A. Edwards
Securing water sources of sufficient quality and quantity poses a major barrier to growing communities. Major investments in capitol and materials are planned in water treatment and distribution system infrastructure over the next several decades, but

Phases of a 2D Bose Gas in an Optical Lattice

September 9, 2010
Author(s)
Karina K. Jimenez Garcia, Yu-Ju Lin, James V. Porto, Ian B. Spielman
Ultra-cold atoms in optical lattices realize essential models in condensed matter physics. Like with most experiments with ultra-cold atoms, our Rubidium-87 Bose Einstein condensate is confined in a harmonic trapping potential that persists even when

Study on Noise Reduction in Up-conversion Single Photon Detectors

September 9, 2010
Author(s)
Lijun Ma, Oliver T. Slattery, Xiao Tang
Up-conversion single photon detector technology has been established as efficient for photons in near infrared range. However, its dark count rate is a major concern for some applications in quantum optics. We have theoretically and experimentally studied

Phase Equilibria of the Ba-Sm-Y-Cu-O System for Coated Conductor Applications

September 8, 2010
Author(s)
Winnie K. Wong-Ng, Guangyao Liu, Zhi Yang, James A. Kaduk, Lawrence P. Cook
The complex phase relationships near the BaO-poor region of the quaternary Ba-Sm-Y-Cu-O oxide system prepared in pure air (pO2 = 22 kPa, 950 ºC) and in 0.1% O2 (pO2=100 Pa, 810 ºC) have been determined. This investigation also included the subsolidus

Scientific Issues with Analysis of Low Amounts of DNA

September 7, 2010
Author(s)
John Butler, Becky Steffen
Faced with limited evidence that yield low amounts of DNA, forensic analysts will continually have to confront the question of how far to push DNA testing techniques. Low copy number (LCN) analysis, also known as low template DNA (LT-DNA) testing, involves

Superconformal Electrodeposition for 3-D Interconnects

September 7, 2010
Author(s)
Thomas P. Moffat, Daniel Josell
Electrodeposition is a key fabrication process used in the state-of-the-art multilevel Cu metallization of microelectronic interconnects from transistor to circuit board length scale. Recent electrochemical surface science and feature filling studies have

Effect of Moisture on Copolymer Fibers based on 5-amino-2-(p-aminophenyl)-benzimidazole.

September 6, 2010
Author(s)
Guillaume Messin, Amanda L. Forster, Kirk D. Rice, Michael A. Riley, Stephanie S. Watson
In recent years, there has been some concern in the soft body armor community that copolymer fibers based on 5-amino-2-(p-aminophenyl)-benzimidazole can release hydrochloric acid, which could potentially be detrimental to other fibers that might come in

Metrological Compatibility and Statistical Consistency

September 5, 2010
Author(s)
Raghu N. Kacker, Ruediger Kessel, Klaus-Dieter Sommer, Xin Bian
The traditional concept of consistency in multiple evaluations of the same measurand is statistical. The statistical view of consistency does not match the modern view of uncertainty in measurement; in particular, it does not apply to the results of

Sub-micron force detection using optically-cooled levitated microspheres

September 3, 2010
Author(s)
Andrew Geraci, Scott B. Papp, John E. Kitching
We propose an experiment using optically trapped and cooled dielectric microspheres for the detection of short-range forces. The center-of-mass motion of a microsphere trapped in vacuum can experience extremely low dissipation and quality factors of 10 12

Epitaxial Graphene Electronic Structure And Transport

September 2, 2010
Author(s)
Joseph A. Stroscio, Walt A. de Heer, Claire Berger, Xiaosong Wu, Yike Hu, Ming Ruan, Phillip First, Robert Haddon, Benjamin Piot, Clement Faugeras, Marek Potemski
Since its inception in 2001, the science and technology of epitaxial graphene on hexagonal silicon carbide has matured into a major international effort and is poised to become the first carbon electronics platform. A historical perspective is presented

PYRAMID MODEL BASED DOWN-SAMPLING FOR IMAGE INPAINTING

September 2, 2010
Author(s)
Hamid Gharavi
Image inpainting is a useful and powerful technique for automatically restoring or removing objects in films and damaged pictures. In the last ten years, many excellent inpainting algorithms have been proposed after Bertalmio et al. [1]. However, no paper

Surface Wrinkling: a Versatile Platform for Measuring Thin Film Properties

September 2, 2010
Author(s)
Jun Y. Chung, Adam J. Nolte, Christopher M. Stafford
Surface instabilities in soft matter have captivated the scientific community for decades. Recently, surface wrinkling has received a great deal of attention due to its simplicity and well-established mechanics of formation. Particularly, the use of

A Channel Propagation Model for the 700 MHz Band

September 1, 2010
Author(s)
Camillo A. Gentile, Nada T. Golmie, Catherine A. Remley, Christopher L. Holloway, William F. Young
Conversion from analog television in the United States combined with the appeal for broadband public safety communications is generating a lot of interest in the so-called 700 MHz band between 698-806 MHz. To our knowledge, no channel propagation model for
