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 Pookpanratana, Katelyn Goetz, Ruslan Ovsyannikov, Erika Giangrisostomi, Emily Bittle, Oana Jurchescu, Steven W. Robey, Christina 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

Fundamentals of Small Business Information Security

March 15, 2017
Author(s)
Celia Paulsen, Gregory A. Witte, Larry Feldman
This bulletin summarizes the information in NISTIR 7621, Revision 1: Small Business Information Security: The Fundamentals. The bulletin presents the fundamentals of a small business information security program.

Jetting of a shear banding fluid in a rectangular duct

March 14, 2017
Author(s)
Paul NMN Salipante, Charles A. Little, Steven D Hudson
We report on a jetting flow instability of shear banding worm-like micelle (WLM) solutions in microfluidic channels with rectangular cross-sections over an intermediate volumetric flow regime. Particle tracking methods are used to measure the three

Synchrophasor Data Quality Attributes and a Methodology for Examining Data Quality Impacts upon Synchrophasor Applications

March 14, 2017
Author(s)
Dhananjay Anand, Allen R. Goldstein, Alison Silverstein, Laurie Miller, Francis Tuffner, Yuri Makarov
Data from synchrophasor devices like phasor measurement units (PMU) is increasingly being used to enhance and improve power grid operations, analysis, and planning applications. However, PMU data often arrive at the application with a variety of data
