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

In-situ Elastic Strain Mapping During Micromechanical Testing Using EBSD

November 14, 2017
Author(s)
Mark McLean, William A. Osborn
Compared to more commonly used strain measurement techniques, EBSD offers improved spatial resolution and measurement sensitivity. Additionally, EBSD can provide the full deformation tensor, whereas other techniques, such as DIC, are limited to only in

VISION EXPERIMENT ON PERCEPTION OF CORRELATED COLOR TEMPERATURE

November 14, 2017
Author(s)
Yoshi Ohno, Hyeyoung Ha, Youngshin Kwak
The correlated color temperature (CCT) is defined by the closest point on the Planckian locus from a light source on the (now obsolete) CIE 1960 (u, v) diagram, while the current standard uniform color space is the CIE 1976 (u', v') diagram. To re-visit

Advanced Electrical Power System Sensors Workshop Report

November 13, 2017
Author(s)
Allen R. Goldstein
The objective of the Advanced Electrical Power Sensors Workshop was to provide input into planning processes being undertaken by the National Institute of Standards and Technology (NIST), Department of Energy (DOE), and the Grid Modernization Laboratory

Overview of the NIST 2016 LoReHLT Evaluation

November 13, 2017
Author(s)
Audrey N. Tong, Lukasz L. Diduch, Jonathan G. Fiscus, Yasaman Haghpanah, Shudong Huang, David M. Joy, Kay Peterson, Ian M. Soboroff
Initiated in conjunction with DARPA's Low Resource Languages for Emergent Incidents (LORELEI) Program, the NIST LoReHLT (Low Re-source Human Language Technology) evaluation series seeks to incubate research on fundamental natural language processing tasks

Spontaneous avalanche dephasing in large Rydberg ensembles

November 13, 2017
Author(s)
Thomas L. Boulier, Eric Magnan, Carlos Bracamontes, James Maslek, Elizabeth Goldschmidt, Jeremey Young, Alexey Gorshkov, Steven Rolston, James V. Porto
Strong dipole-exchange interactions due to spontaneously produced contaminant states can trigger rapid dephasing in many-body Rydberg ensembles [E. Goldschmidt et al., PRL 116, 113001 (2016)]. Such broadening has serious implications for many proposals to

Time Distribution Alternatives for the Smart Grid Workshop Report

November 13, 2017
Author(s)
Allen R. Goldstein
The National Institute of Standards and Technology (NIST) hosted the Time Distribution Alternatives for the Smart Grid Workshop at its Gaithersburg, Maryland Campus on March 21, 2017. The event, co-hosted by the U.S. Department of Energy, brought together

Valley blockade in a silicon double quantum dot

November 13, 2017
Author(s)
Justin K. Perron, Michael Gullans, Jacob Taylor, Michael Stewart, Neil M. Zimmerman
Electrical transport in double quantum dots (DQD) is useful for illuminating many interesting aspects of the carrier states in quantum dots. Here we show data comparing bias triangles (i.e., regions of allowed current in DQDs) at positive and negative bias

Experiments to Quantify Firebrand Production from Roofing Assembly Combustion

November 12, 2017
Author(s)
Samuel Manzello, Sayaka Suzuki, Tomohiro Naruse
Large outdoor fires present a risk to the built environment. One example often in the international media reports are wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires. Another example are large urban fires

Investigation on Firebrand Generation from Reduced-scale Mock-ups

November 12, 2017
Author(s)
Samuel Manzello, Sayaka Suzuki
Firebrands generated from structures are known to be a source of rapid flame spread within communities in large outdoor fires, such as wildland-urban (WUI) fires, and urban fires. It is important to better understand firebrand generation mechanism. To this

Reference correlations for the thermal conductivity of copper, gallium, indium, iron, lead, nickel and tin

November 12, 2017
Author(s)
Marc J. Assael, Arsenios Chatzimichailidis, K.D. Antoniadis, William A. Wakeham, Marcia L. Huber, Hiroyuki Fukuyama
The available experimental data for the thermal conductivity of liquid copper, gallium, indium, iron, lead, nickel and tin have been critically examined with the intention of establishing thermal conductivity reference correlations. All experimental data
