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
