Candice Z. Ulmer, Jared Ragland, Jeremy P. Koelmel, N. Alan Heckert, Christina Jones, Timothy J. Garrett, Richard A. Yost, John Bowden
As advances in analytical separation techniques, mass spectrometry instrumentation, and data processing platforms continue to spur growth in the lipidomics field, more structurally unique lipid species are detected and annotated. The lipidomics community

Recommendation for the Triple Data Encryption Algorithm (TDEA) Block Cipher

November 17, 2017
Author(s)
Elaine B. Barker, Nicky W. Mouha
This publication specifies the Triple Data Encryption Algorithm (TDEA), including its primary component cryptographic engine, the Data Encryption Algorithm (DEA). TDEA is intended to be used with a Special Publication (SP) 800-38-series-compliant mode of

Instrumented impact testing of miniaturized Charpy specimens of AM Ti 6Al 4V

November 16, 2017
Author(s)
Enrico Lucon, Nikolas W. Hrabe
An investigation on the impact toughness properties of wrought and additively-manufactured (AM) Ti 6Al 4V was conducted at NIST Boulder, by means of instrumented impact tests on miniaturized Charpy specimens. Full transition curves for absorbed energy and

Modeling the Internet of Things (& People): A Foundational Approach

November 16, 2017
Author(s)
Spencer J. Breiner, Eswaran Subrahmanian, Ram D. Sriram
This talk provides an overview of recent NIST work in the Internet of Things (IoT) domain in the Information Technology Laboratory. We begin with some examples and illustrations of the range of IoT systems. In addition to the obvious cyber physical aspects

NIST Handbook 133: Checking the Net Contents of Packaged Goods (2018 Ed.)

November 16, 2017
Author(s)
Linda D. Crown, Lisa Warfield, David Sefcik
This handbook has been prepared as a procedural guide for the compliance testing of net contents statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance results of packaging, distribution, and sale of

Requirements for Spectrum Monitoring in Industrial Environments

November 16, 2017
Author(s)
Murat Aksu, Richard Candell
Spectrum monitoring serves as the eyes and ears of the spectrum management process and helps spectrum managers to plan and use frequencies, avoid incompatible usage, and identify sources of harmful interference. The key objective for this research at NIST

Sketchnote summary of "The Backscattering Story: A Personal View"

November 16, 2017
Author(s)
Robert M. Dimeo
In August 2014, Dr. Anton Heidemann published a short, personal history of the development of neutron backscattering. His fascinating article 1 described the technical innovations that were made during the development of this technique, and it is

Crystallography of Functional Materials (Editorial Comments)

November 15, 2017
Author(s)
Winnie K. Wong-Ng, Claudia J. Rawn
The goal of this special issue is to obtain new insights into the roles of crystallography in functional materials. This special issue consists of eight chapters illustrating the structure and property relationships, as well as applications of selected

Rate effects on transformation kinetics in a metastable austenitic stainless steel

November 15, 2017
Author(s)
Rakan Alturk, William E. Luecke, Steven Mates, A Araujo, K. S. Raghavan, Fadi Abu-Farha
In this study, the effects of strain rate on the mechanical properties and the strain-induced austenite-to-martensite transformation in 201 austenitic stainless steel (SS201) were investigated. This grade was selected as a low-cost stainless steel with

Simultaneous, Full Characterization of a Single-Photon State

November 15, 2017
Author(s)
Tim O. Thomay, Sergey Polyakov, Elizabeth A. Goldschmidt, Glenn S. Solomon, Olivier Gazzano, Vivien Loo
As single-photon sources become more mature and are used more often in quantum information, communications, and measurement applications, their characterization becomes more important. Single-photon-like light is often characterized by its brightness, as

Structural Aspects of Porphyrins for Functional Materials Applications

November 15, 2017
Author(s)
Lawrence P. Cook, Greg Brewer, Winnie Wong-Ng
Porphyrinic compounds comprise a diverse group of materials which have in common the presence of one or more cyclic tetrapyrrole units known as porphyrins in their molecular structures. The resulting aromaticity gives rise to the semiconducting properties

VISION EXPERIMENT ON CHROMA SATURATION PREFERENCE IN DIFFERENT HUES

November 15, 2017
Author(s)
Yoshihiro Ohno, Youngshin Kwak, Semin Oh
Increase of chroma is known to be a major factor for color quality preference in lighting, and gamut area measures are often used to evaluate preference aspects. However, gamut area accounts for chroma differences equally for all hue directions

Collision-Induced Dissociation of Deprotonated Peptides. Relative Abundance of Side-Chain Neutral Losses, Residue-Specific Product Ions, and Comparison with Protonated Peptides

November 14, 2017
Author(s)
Yuxue Liang, Pedatsur Neta, Xiaoyu (Sara) Yang, Stephen E. Stein
High-accuracy MS/MS spectra of deprotonated ions of 390 dipeptides and 137 peptides with 3 to 6 residues are studied. Many amino acid residues undergo neutral losses from their side chains. The most abundant is the loss of acetaldehyde from threonine. The
