Thermographic and FE Simulation of the DMLS Process at NIST

February 4, 2015
Author(s)
Brandon M. Lane, Li Ma, Shawn P. Moylan, M A. Donmez, Eric P. Whitenton, Daniel J. Falvey
A major effort of the Measurement Science for Additive Manufacturing Program at NIST is to provide high quality, well-defined temperature measurement of the DMLS process to support and validate multi-physics simulations. However, the dynamic, complex

Understanding the blue color in antique mosaic mirrored glass from the Temple of the Emerald Buddha, Thailand

February 4, 2015
Author(s)
Bruce D. Ravel, Wantana Klysubun, Christoph Hauzenberger, Prapong Klysubun, Yuying Huang, Weeraya Wongtepa, Panidtha Sombunchoo
Two samples of the blue glass produced in the middle 19th century from the Temple of the Emerald Buddha in Bangkok, Thailand, were studied in order to understand the origin of its blue color. The oxide components and trace elements are quantitatively

An Iodide-Based Li 7 P 2 S 8 I Superionic Conductor

February 3, 2015
Author(s)
Ezhiylmurugan Rangasamy, Zengcai Liu, Mallory Gobet, Kartik Pilar, Gayatri Sahu, Wei Zhou, Hui Wu, Steve Greenbaum, Chengdu Liang
A Li 7P 2S 8I solid state Li-ion conductor derived from β-Li 3PS 4 and LiI demonstrates exceptional electrochemical stability. The oxidation instability if 'I' is subverted via its incorporation into the coordinated structure. The inclusion of 'I' also

Critical Examination of the Colloidal Particle Model of Globular Proteins

February 3, 2015
Author(s)
Prasad S. Sarangapani, Steven D Hudson, Ronald L. Jones, Jack F. Douglas, Jai A. Pathak
Recent studies of globular protein solutions have uniformly adopted a colloidal view of proteins as particles, a perspective that neglects the polymeric primary structure of these biological macromolecules, their intrinsic flexibility and their ability to

Report on Pairing-based Cryptography

February 3, 2015
Author(s)
Dustin Moody, Rene C. Peralta, Ray A. Perlner, Andrew R. Regenscheid, Allen L. Roginsky, Lidong Chen
This report summarizes study results on pairing-based cryptography. The main purpose of the study is to form NIST’s position on standardizing and recommending pairing-based cryptography schemes currently published in research literature and standardized in

Building Analytical Support for Homeland Security

February 2, 2015
Author(s)
Sanjay Jain, Charles W. Hutchings, Yung-Tsun Lee
This chapter discusses modeling and simulation as a significant means for providing analytical support for homeland security problem solving and decision making that involves what can be considered a complex and dynamic system of systems - the current

EFFECT OF SIDING TREATMENT ON FIREBRAND PRODUCTION FROM BUILDING COMPONENTS

February 2, 2015
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Wildfires which spread into a community, commonly known as Wildland-Urban Interface (WUI) fires, is a significant problem all over the world. Post-fire investigations have suggested that firebrands are the major cause of structure ignitions. Yet, few

Experimental and Numerical Simulations of the Gas-Phase Effectiveness of Phosphorus Compounds

February 2, 2015
Author(s)
Nicolas Bouvet, Gregory T. Linteris, Valeri I. Babushok, Fumiaki Takahashi, Viswanath R. Katta
The effectiveness of phosphorus-containing compounds as gas-phase combustion inhibitors varies widely with flame type. To understand this behavior, experiments are performed with dimethyl methylphosphonate (DMMP) added to the oxidizer stream of methane-air

NIST Time and Frequency Bulletin

February 2, 2015
Author(s)
Petrina C. Potts
The Time and Frequency Bulletin provides information on performance of time scales and a variety of broadcasts (and related information) to users of the NIST services

SIM.RI(I)-K3 Comparison of Calibration Coefficients at Radiotherapy Level for Orthovoltage X-ray Beams

February 2, 2015
Author(s)
C M. O'Brien, J.P. McCaffrey, H Shen, M Saravi, G M. Ortiz, G Stefanic, M Carlos, C.N.M. da Silva, J L. Alvarez, V Tovar
Air-kerma calibration coefficients were compared at the radiotherapy level for orthovoltage x-ray beams in the SIM.RI(I)-K3 comparison for members of the Sistema Interamericano de Metrología (SIM). Five SIM laboratories participated in the comparison: NIST

True Composition and Structure of Hexagonal "YAlO 3 ", Actually Y 3 Al 3 O 8 CO 3

February 2, 2015
Author(s)
Jun Li, Andrew E. Smith, Peng Jiang, Judith K. Stalick, Arthur W. Sleight, M. A. Subramanian
The discovery of a brilliant blue color on introduction of Mn 3+ into the trigonal bipyramidal (TBP)sites in YInO 3 has led to a search for other hosts for Mn 3+ in TBP coordination. An obvious choice would be YAlO 3. This compound, which has only been

Beyond the International Year of Crystallography

February 1, 2015
Author(s)
Andrew J. Allen, Janos Hajdu, Anke R. Kaysser-Pyzalla
It is now one year since all International Union of Crystallography (IUCr) journals became online only, and this is just one of the developments during the International Year of Crystallography, IYCr 2014. Perhaps, most conspicuously, IUCr’s new flagship

MICROARRAY APPLICATIONS TO UNDERSTAND THE IMPACT OF EXPOSURE TO ENVIRONMENTAL CONTAMINANTS IN WILD DOLPHINS (Tursiops truncatus).

February 1, 2015
Author(s)
Annalaura Mancia, Luigi Abelli, John Kucklick, Teresa Rowles, Randall Wells, Brian C. Balmer, Aleta Hohn, John Baatz, James Ryan
It is increasingly common to monitor the marine environment and establish geographic trends of environmental contamination by measuring contaminant levels in animals from higher trophic levels. The health of an ecosystem is largely reflected in the health
