Engineering Near-Field SEIRA Enhancements in Plasmonic Resonators

January 20, 2016
Author(s)
Jungseok Chae, Basudev Lahiri, Andrea Centrone
Engineering of the optical resonances in plasmonic resonators arrays is achieved by virtue of the intrinsic properties to the constituent structures such as composition, size and shape and by controlling the inter-resonator interactions by virtue the array

Measurement Challenges and Metrology for Monitoring CO2 Emissions from Smokestacks Workshop Summary

January 20, 2016
Author(s)
Aaron N. Johnson, Rodney A. Bryant, Tamae M. Wong, James R. Whetstone, Eric Harman, Woong Kang, Keith A. Gillis, Hsin-Hung Lee, Iosif I. Shinder, Liang Zhang
On April 20-21, 2015, NIST hosted a workshop that, through measurement science, enabled the owners of stationary sources (primarily the electric power industry) and their regulatory agencies (federal and state) to better characterize greenhouse gas (GHG)

The Influence of Water Activity on the Hydration Rates of Triclinic Tricalcium Silicate

January 20, 2016
Author(s)
Tandre Oey, Aditya Kumar, Gabriel Falzone, Jian Huang, Sierra Kennison, Mathieu Bauchy, Narayanan Neithalath, Jeffrey W. Bullard, Gaurav Sant
Tricalcium silicate stops hydrating at relative humidities (RH) less than 80 %. But the rate at which its hydration rate decreases as a function of the RH has not yet been elucidated. By invoking correspondence between RH and water activity (aH, unitless)

Absolute Energy Calibration of X-ray TESs with 0.04 eV Uncertainty at 6.4 keV in a Hadron-Beam Environment

January 19, 2016
Author(s)
Hideyuki Tatsuno, William B. Doriese, Douglas A. Bennett, Catalina Curceanu, Joseph W. Fowler, Johnathon D. Gard, Fredrick P. Gustafsson, Tadashi Hashimoto, Ryugo S. Hayano, James P. Hays-Wehle, Gene C. Hilton, Mihail Iliescu, Shigeru Ishimoto, Kenta Itahashi, Masashiko Iwasaki, Keisuke Kuwabara, Yue Ma, Johann Marton, Hirofumi Noda, Galen C. O'Neil, Shinji Okada, Haruhiko Outa, Carl D. Reintsema, Masaharu Sato, Daniel R. Schmidt, Hexi Shi, Ken Suzuki, Takatoshi Suzuki, Jens Uhlig, Joel N. Ullom, Eberhard Widmann, Shinya Yamada, Johann Zmeskal, Daniel S. Swetz
A performance evaluation of superconducting transition-edge sensors (TESs) in the environment of a pion beam line at a particle accelerator is presented. Averaged across the 209 functioning sensors in the array, the achieved energy resolution is 5.2 eV

SVClassify: a method to use multiple datasets to classify candidate structural variants into true positives and false positives

January 16, 2016
Author(s)
Justin M. Zook, Hemang M. Parikh, Desu Chen, Hariharan K. Iyer, Marc L. Salit, Wolfgang Losert
The human genome contains variants ranging in size from small single nucleotide polymorphisms (SNPs) to large structural variants (SVs). While high-quality benchmark small variant calls have recently been developed by the Genome in a Bottle Consortium, no

Imaging Nanophotonic Modes of Microresonators using a Focused Ion Beam

January 15, 2016
Author(s)
Kevin A. Twedt, Jie J. Zou, Marcelo I. Davanco, Kartik A. Srinivasan, Jabez J. McClelland, Vladimir A. Aksyuk
Optical microresonators have proven powerful in a wide range of applications, including cavity quantum electrodynamics, biosensing, microfludics, and cavity optomechanics. Their performance depends critically on the exact distribution of optical energy

Morphological origins of polarization-induced scattering anisotropy from organic thin films

January 14, 2016
Author(s)
Eliot Gann, Brian A. Collins, Maolong Tang, John R. Tumbleston, Subhrangsu Mukherjee, Harald W. Ade
Anisotropic scattering patterns have been observed from organic thin films that are isotropic on the scale of the probe in polarized resonant X-ray scattering experiments. The symmetry is broken by local correlations between molecular orientation and

Polymer Glass-Formation in Variable Dimension

January 14, 2016
Author(s)
Jack F. Douglas, Freed Karl, Wensheng Xu
We explore the nature of glass-formation in variable spatial dimensionality (d) based on the generalized entropy theory, a synthesis of the Adam-Gibbs model with direct computation of the configurational entropy of polymer fluids using an established

Survival analysis approach to account for non-exponential decay rate effects in lifetime experiments

January 13, 2016
Author(s)
Kevin J. Coakley, Maynard S. Dewey, Michael G. Huber, Hans P. Mumm, Alan Keith Thompson, Andrew T. Yue, C. R. Huffer, P. R. Huffman, C. M. O'Shaughnessy, K. W. Schelhammer, D. E. Marley
In experiments that measure the lifetime of trapped particles, in addition to loss mechanisms with exponential survival probability functions, particles can be lost by mechanisms with non-exponential survival probability functions. Failure to account for

FIRE-STRUCTURE INTERACTION EXPERIMENT PLAN FOR FULL-SCALE COMPOSITE FLOOR SYSTEM

January 12, 2016
Author(s)
Lisa Y. Choe, John L. Gross, William L. Grosshandler, Matthew F. Bundy
The newly-constructed National Fire Research Laboratory (NFRL) at the National Institute of Standards and Technology (NIST) provides an opportunity for the structural fire research community to undertake experimental research here-to-for not possible. This

Logic circuit prototypes for three-terminal magnetic tunnel junctions with mobile domain walls

January 12, 2016
Author(s)
Jean Anne Currivan-Incorvia, S. Siddiqui, S. Dutta, Eric R. Evarts, J. Zhang, D. Bono, C A. Ross, M. A. Baldo
Spintronic computing promises superior energy efficiency and nonvolatility compared to conventional field-effect transistor logic. But, it has proven difficult to realize spintronic circuits with a versatile, scalable device design that is adaptable to
