Sensitivity of gold nano conductors to common contaminations ab initio results

May 29, 2013
Author(s)
Shmuel Barzilai, Francesca M. Tavazza, Lyle E. Levine
Gold nanowire chains are considered a good candidate for nanoelectronic devices because they exhibit remarkable structural and electrical properties. A previous study shows that the beryllium terminated BeO (0001) surface may be a useful platform for

Thermal Decomposition Kinetics of 1,3,5-Triisopropylcyclohexane

May 29, 2013
Author(s)
Raina V. Gough, Jason A. Widegren, Thomas J. Bruno
Recent surrogate diesel fuel mixture development identified the need for a multiply-substituted, low cetane number, high molecular mass monocycloalkane component. On the basis of a thermophysical property evaluation and prediction, 1,3,5

Continuum-based free vibration of circular trigonal and isotropic plates

May 28, 2013
Author(s)
Ward L. Johnson, Paul R. Heyliger
The free vibration behavior of completely unrestrained elastic circular plates with trig- onal and isotropic material symmetry is studied using approximate solutions to the three- dimensional theory of linear elasticity. Of primary interest are 1) the

Practical Strategies for QKD Key Production

May 28, 2013
Author(s)
Alan Mink, Anastase Nakassis
We present the quantum key distribution (QKD) secure key ratio expression in a form that exposes the parameters that affect the Reconciliation (error correction) stage. Reconciliation is the least well understood in practical terms and is typically

Use of RF-Based Technique as a Metrology Tool for TSV Reliability Analysis

May 28, 2013
Author(s)
Chukwudi A. Okoro, Yaw S. Obeng, Jan Obrzut, Pavel Kabos, Klaus Hummler
In this work, we used radio frequency (RF) based measurement technique is used as a prognostic tool for the assessment of the effect of thermal cycling on the reliability of through-silicon via (TSV) stacked dies. It was found that RF signal integrity in

X-Ray Micro-Beam Diffraction Determination of Full Stress Tensors in Cu TSVs

May 28, 2013
Author(s)
Chukwudi A. Okoro, Lyle E. Levine, Oleg A. Kirillov, Yaw S. Obeng, Ruqing Xu, Jonathan Z. Tischler, Wenjun Liu, Klaus Hummler
We report the first non-destructive, depth resolved determination of the full stress tensor in Cu through-silicon vias (TSVs), using synchrotron based micro-beam X-ray diffraction. Two adjacent Cu TSVs were studied; one deliberately capped with SiO2, the

Surface mediated assembly of small, metastable gold nanoclusters

May 27, 2013
Author(s)
John M. Pettibone, William A. Osborn, Konrad Rykaczewski, Albert A. Talin, John E. Bonevich, Jeffrey W. Hudgens
The unique properties of metallic nanoclusters are attractive for numerous commercial and industrial applications but are generally less stable than nanocrystals. Thus, developing methodologies for stabilizing nanoclusters and retaining their enhanced

Chapter 13. Color Quality of White LEDs

May 24, 2013
Author(s)
Yoshihiro Ohno
This chapter overviews the fundamentals of chromaticity and color rendering as the two important aspects of color quality of light sources for general illumination, with special focus on the use for solid state light sources. The section for chromaticity

The Development and Implementation of Quality Assurance Programs to Support Nutritional Measurements

May 24, 2013
Author(s)
Lane C. Sander, Mary Bedner, David L. Duewer, Katrice A. Lippa, Melissa M. Phillips, Karen W. Phinney, Catherine A. Rimmer, Michele M. Schantz, Katherine E. Sharpless, Susan Tai, Jeanice M. Brown Thomas, Stephen A. Wise, Laura J. Wood, J. M. Betz, Paul M. Coates
The National Institute of Standards and Technology administers quality assurance programs devoted to improving measurements of nutrients and related metabolites in foods, dietary supplements, and serum and plasma samples. These programs have been developed

Toward the Development of a High Strain Rate Testing Standard for Advanced Fibers

May 24, 2013
Author(s)
Gale A. Holmes, Jae Hyun Kim, Nathanael A. Heckert, Walter G. McDonough, Stefan D. Leigh, Kirk D. Rice
The use of advanced fibers in applications where they are subjected to extremely energetic events has necessitated the need to develop measurement tools that quantify their properties at high strain rates (HSR). The split Hopkinson tension bar (SHTB) has
