Pore Size Distribution and Accessible Pore Size Distribution in Bituminous Coals

October 1, 2012
Author(s)
Richard Sakurovs, Lilin He, Yuri B. Melnichenko, Andrzej P. Radlinski, Tomasz Blach, Hartmut Lemmel, David F. Mildner
Contrast-matching ultra-small-angle neutron scattering (USANS) and small-angle neutron scattering (SANS) techniques have been used to determine the fraction of the pores that are inaccessible to deuterated methane, CD 4, in 23 coals over the range of pores

Sequential Estimation of Timebase Corrections for an Arbitrarily Long Waveform

October 1, 2012
Author(s)
Chih-Ming Wang, Paul D. Hale, Jeffrey A. Jargon, Dylan F. Williams, Catherine A. Remley
We present a procedure for correcting the timebase distortion and jitter of temporal waveforms of arbitrary lengths. This is achieved by estimating the timebase distortion and jitter sequentially with overlapping measurements and using the information in

The Juliet 1.1 C/C++ and Java Test Suite

October 1, 2012
Author(s)
Frederick E. Boland Jr., Paul E. Black
The Juliet Test Suite 1.1 is a collection of over 81,000 synthetic C/C++ and Java programs with known flaws. These programs are useful as test cases for testing the effectiveness of static analyzers and other software assurance tools, and are in the public

Interference Mitigation Using Adaptive Schemes in Body Area Networks

September 30, 2012
Author(s)
Wen-Bin Yang, Kamran Sayrafian
Considering the medical nature of the information carried in Body Area Networks (BAN), interference from coexisting wireless networks or even other nearby BANs could create serious problems on their operational reliability. As practical implementation of

Multiexciton dynamics in infrared-emitting colloidal nanostructures probed by a superconducting nanowire single-photon detector

September 30, 2012
Author(s)
Richard L. Sandberg, Lazaro A. Padilha, Mumtaz Qazilbash, Wan Ki Bae, Richard D. Schaller, Jeffrey M. Pietryga, Martin Stevens, Burm Baek, Sae Woo Nam, Victor I. Klimov
Carrier multiplication (CM) is the process in which absorption of a single photon produces multiple electron-hole pairs. Here, we evaluate the effect of particle shape on CM efficiency by conducting a comparative study of spherical nanocrystal quantum dots

SCIENCE-BASED METRICS FOR PRODUCT SUSTAINABILITY ASSESSMENT

September 30, 2012
Author(s)
Barbara C. Lippiatt
Consumers and manufacturers need compelling metrics, tools, and data supporting investments in sustainable products. Today’s marketplace is fraught with sustainability claims that are often based on incomplete, anecdotal evidence that is difficult to

A high resolution gamma-ray spectrometer based on superconducting microcalorimeters

September 28, 2012
Author(s)
Douglas A. Bennett, Robert D. Horansky, Daniel R. Schmidt, Andrew Hoover, Ryan Winkler, Bradley K. Alpert, James A. Beall, William B. Doriese, Joseph W. Fowler, Gene C. Hilton, Kent D. Irwin, Nathan J. Hoteling, Vincent Y. Kotsubo, John A. Mates, Galen C. O'Neil, Michael W. Rabin, Carl D. Reintsema, Francis J. Schima, Daniel S. Swetz, Leila R. Vale, Joel N. Ullom
Improvements in superconductor device fabrication, detector hybridization techniques, and superconducting quantum interference device readout have made square-centimeter-sized arrays of gammaray microcalorimeters, based on transition-edge sensors (TESs)

Optimization of Dispersion and Surface Pretreatment for Single GaN Nanowire Devices

September 28, 2012
Author(s)
Norman A. Sanford, Kristine A. Bertness, Andrew M. Herrero
The correlation of residual contamination with void formation at the contact/SiO2 interface for single GaN NW devices was investigated. The morphology at the metal/SiO2 interface was observed by removing the annealed Ni/Au films from the SiO2 with carbon

A Model for Geometry-Dependent Errors in Length Artifacts

September 27, 2012
Author(s)
Daniel S. Sawyer, Brian Parry, Christopher J. Blackburn, Balasubramanian Muralikrishnan, Steven D. Phillips
We present a detailed model of dimensional changes in long length artifacts, such as step gauges and ball bars, due to bending under gravity. The comprehensive model is based on evaluation of the gauge points relative to the neutral bending surface. It

MEMS Kinematics by Super-Resolution Fluorescence Microscopy

September 27, 2012
Author(s)
Craig D. McGray, Samuel M. Stavis, Joshua Giltinan, Eric Eastman, Samara L. Firebaugh, Jenelle Piepmeier, Jon C. Geist, Michael Gaitan
Super-resolution fluorescence microscopy is used for the first time to study the nanoscale kinematics of a MEMS device in motion across a surface. A device under test is labeled with fluorescent nanoparticles that form a microscale constellation of near

Revised Guide Helps Organizations Handle Security-Related Incidents

September 27, 2012
Author(s)
Shirley M. Radack
This bulletin summarizes the information that is included in NIST Special Publication (SP) 800-61 Revision 2, Computer Security Incident Handling Guide. This publication assists organizations in establishing computer security incident response capabilities

Thermal Decomposition of 1-Pentyl Radicals at High Pressures and Temperatures

September 27, 2012
Author(s)
Andrea Comandini, Iftikhar A. Awan, Jeffrey A. Manion
Complementary shock-tube studies at the National Institute of Standards and Technology (NIST) and the University of Illinois at Chicago (UIC) have been used to examine the decomposition reactions of the 1-pentyl radical at temperatures of 833 K to 1130 K

Upper roughness limitations on the TIS/RMS relationship

September 27, 2012
Author(s)
J C. Stover, Sven Schroeder, Thomas Germer
The relationship between total integrated scatter (TIS) and root mean square (rms) roughness was developed in the radar literature and enabled the first use of scatter measurements to monitor optical roughness. This relationship has been used and misused
