Double-integrating-sphere system at the National Institute of Standards and Technology in support of measurement standards for the determination of optical properties of tissue-mimicking phantoms

October 27, 2015
Author(s)
Paul Lemaillet, Jeeseong C. Hwang, David W. Allen
There is a need for a common reference point that will allow for the comparison of the optical properties of tissue mimicking phantoms. This paper provides a brief review of the methods that have been used to measure tissue mimicking phantoms. The review

Characterizing a Device's susceptibility to broadband signals: A case study

August 4, 2014
Author(s)
Jason B. Coder, John M. Ladbury, David Hunter
It is common for electronic devices to be tested for their susceptibility to radiated signals they may be exposed to during their normal operation. A reverberation chamber is well suited to perform this type of testing because it can expose the device

Applications of Surface Metrology in Toolmark Identification

Xiaoyu Alan Zheng, Johannes A. Soons, Theodore V. Vorburger, Jun-Feng Song, Thomas Brian Renegar, Robert M. Thompson
Surface metrology is commonly used to characterize functional engineering surfaces. The technologies developed offer opportunities to improve forensic toolmark identification. In 2009, a report by the National Academies called into question, amongst others

THE EFFECT OF MICROSTRUCTURE ON THE HYDROGEN-ASSISTED FATIGUE OF PIPELINE STEELS

July 14, 2013
Author(s)
Andrew J. Slifka, Elizabeth S. Drexler, Robert L. Amaro, Damian S. Lauria, April Stevenson, Douglas G. Stalheim, Louis E. Hayden
Tests on the fatigue crack growth rate were conducted on four pipeline steels, two of grade API 5L- X52 and two API 5L-X70. One X52 material was from the mid 1960s and the other was manufactured in 2011. The two X70 materials had a similar vintage and

Certification of SRM 2492: Bingham Paste Mixture for Rheological Measurements

June 7, 2012
Author(s)
Chiara F. Ferraris, Paul E. Stutzman, William F. Guthrie
Rheological measurements are often performed using a rotational rheometer. In this type of rheometer, the tested fluid is sheared between two surfaces, one of which is rotating [1]. Usually, the angular velocity is imposed and the response of the material

Functional Requirements of a Model for Kitting Plans

March 22, 2012
Author(s)
Stephen B. Balakirsky, Zeid Kootbally, Thomas R. Kramer, Rajmohan Madhavan, Craig I. Schlenoff, Michael O. Shneier
Industrial assembly of manufactured products is often performed by first bringing parts together in a kit and then moving the kit to the assembly area where the parts are used to assemble products. Kitting, the process of building kits, has not yet been

Calibrations of Multi-Hole Pitot Tubes Depend on Tubulence

March 19, 2012
Author(s)
Iosif I. Shinder, Christopher J. Crowley, Michael R. Moldover
NIST is developing techniques to calibrate 2- and 3-dimensional anemometer systems (such as multi-hole pitot tubes) with a resolution of 0.3 %. The pitch and yaw response of multi-hole pitot tubes is complicated; therefore, calibrations require hundreds of

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

Selective Binding of RNAse B Glycoforms by Polydopamine-immobilized Concanavalin A

June 10, 2009
Author(s)
Todd A. Morris, Alexander W. Peterson, Michael J. Tarlov
Glycoanalysis is important in the manufacture and quality control of protein therapeutics. An emerging method for glycoanalysis is the use of lectin arrays. Critical to the performance of these arrays is the immobilization of the lectin molecules
