Reference Correlation for the Viscosity of Carbon Dioxide

March 21, 2017
Author(s)
Arno D. Laesecke, Chris D. Muzny
A comprehensive database of experimental and computed data for the viscosity of carbon dioxide (CO2) was compiled and a new reference correlation was developed. Literature results based on an ab initio potential energy surface were the foundation of the

Chiral magnetoresistance in Pt/Co/Pt zigzag wires

March 20, 2017
Author(s)
Kyoung-Whan Kim, Yuxiang Yin, Dong-Soo Han, June-Seo Kim, Lavrijsen Reinoud, Kyung-Jin Lee, Seo--Won Lee, Hyun-Woo Lee, Henk Swagten, Bert Koopmans
The Rashba effect leads to a chiral rotation of conduction spins while the Dzyaloshinskii-Moriya interaction (DMI) fixes the chirality of the profile of local spins. We predict that these two spin systems interact with each other via s-d exchange, and

Frontiers of Characterization and Metrology for Nanoelectronics: 2017

March 20, 2017
Author(s)
Erik M. Secula, David G. Seiler
The 2017 International Conference on Frontiers of Characterization and Metrology for Nanoelectronics (FCMN) has the goal of bringing together scientists and engineers interested in all aspects of the characterization and measurement technology needed for

Structural Polymorphism in "Kesterite" Cu 2 ZnSnS 4 : Raman Spectroscopy and First-principles Calculations Analysis

March 20, 2017
Author(s)
Mirjana NMN Dimitrievska, Federica Boero, Alexander P. Litvinchuk, Simona Delsante, Gabriella Borzone, Alejandro Perez-Rodriguez, Victor Izquierdo-Roca
This work presents a comprehensive analysis of the structural and vibrational properties of the kesterite Cu 2ZnSnS 4 (CZTS, I-4 space group) as well as its polymorphs with the space group P-42c and P-42m, from both experimental and theoretical point of

Validation of Robotics for Antenna Measurements

March 18, 2017
Author(s)
Jeffrey R. Guerrieri
This paper presents recent measurements using the newly developed Configurable Robotic Millimeter-Wave Antenna (CROMMA) facility by the Antenna Metrology Lab at the National Institute of Standards and Technology (NIST). NIST set out to develop an antenna

A Radio Frequency Radiation Reverberation Chamber Exposure System for Rodents

March 17, 2017
Author(s)
Perry F. Wilson, John M. Ladbury, Galen H. Koepke, Capstick Myles, Niels Kuster, Sven Kuhn, Veronica Berdinas-Torres, Yijian Gong, David McCormick, James Gauger, Ronald Melnick
In this paper we present the novel design features, their technical implementation, and an evaluation of the radio frequency (RF) exposure systems developed for the National Toxicology Program (NTP) of the National Institute of Environmental Health

Efficient Simulation of Secondary Fluorescence via NIST DTSA-II Monte Carlo

March 17, 2017
Author(s)
Nicholas Ritchie
Secondary fluorescence, the final term in the familiar matrix correction triumvirate Z·A·F, is the most challenging for Monte Carlo models to simulate. In fact, only two implementations of Monte Carlo models commonly used to simulate electron probe x-ray

Life Time Dosimetric Assessment for Mice and Rats Exposed to Cell Phone Radiation in Reverberation Chambers

March 17, 2017
Author(s)
Perry F. Wilson, John M. Ladbury, Galen H. Koepke, Yijian Gong, Myles Capstick, Keven Kuhn, David L. McCormick, Ronald L. Melnick, Niels Kuster
In this paper, we present a detailed life time dosimetry analysis for individually housed rodents exposed to radio frequency (RF) signals. The unrestrained rodents were exposed in reverberation chambers for 2 years at three whole-body averaged specific

Electronic Structure of Single Crystal a-Perylene

March 16, 2017
Author(s)
Sujitra J. Pookpanratana, Katelyn Goetz, Ruslan Ovsyannikov, Erika Giangrisostomi, Emily G. Bittle, Oana Jurchescu, Steven W. Robey, Christina A. Hacker
In organic electronics, the highest estimated charge mobility in a device is typically achieved when the organic semiconductor is a single crystal. However, the measurement of the electronic and chemical structure of organic single crystals by

Fourier transform spectroscopy of a spin-orbit coupled Bose gas

March 16, 2017
Author(s)
Ian B. Spielman, Erin Marshall, Dimitry Trypogeorgos, Ana ValdCuriel
We describe a Fourier transform spectroscopy technique for directly measuring band structures, and apply it to a spin-1 spin-orbit coupled Bose-Einstein condensate. In our technique, we suddenly change the systems Hamiltonian by adding a spin- orbit

Neuroelectronic Device Process Development and Challenge

March 16, 2017
Author(s)
Jessie Zhang, Gymama Slaughter, Matthew Robinson, Joel Tyson
One of the major challenges of brain activity monitoring is to obtain high quality signals from the brain using metal electrodes. The probes consisting of metal electrodes have to be thin enough without damaging the tissue while maintaining good contact to

NIST Micronutrients Measurement Quality Assurance Program Winter and Summer 2016 Comparability Studies: Results for Round Robin LXXIX and LXXX Fat-Soluble Vitamins and Carotenoids in Human Serum

March 16, 2017
Author(s)
Jeanice M. Brown Thomas, David L. Duewer
The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat-soluble vitamins and carotenoids in human serum and plasma. This report describes the design

29Si NMR and SAXS investigation of the hybrid organic-inorganic glasses obtained by consolidation of the melting gels

March 15, 2017
Author(s)
Andrei Jitianu, Sylvian Cadars, Fan Zhang, Gabriela Rodriguez, Quentin Picard, Mario Aparicio, Jadra Mosa, Lisa C. Klein
This study is focused on structural characterization of hybrid glasses obtained by consolidation of melting gels. The melting gels were prepared in molar ratios of methyltriethoxysilane (MTES) and dimethyldiethoxysilane (DMDES) of 75%MTES-25%DMDES and 65
