Rapid Wafer-Scale Growth of Polycrystalline 2H-MoS2 by Pulsed Metalorganic Chemical Vapor Deposition

July 12, 2017
Author(s)
Berc Kalanyan, William A. Kimes, Ryan Beams, Stephan J. Stranick, Elias J. Garratt, Irina Kalish, Albert Davydov, Ravindra Kanjolia, James E. Maslar
High volume manufacturing of devices based on transition metal dichalcogenide (TMD) ultra-thin films will require deposition techniques that are capable of reproducible wafer-scale growth with monolayer control. To date, TMD growth efforts have largely

The Empirical Core-Chain Model

July 12, 2017
Author(s)
Boualem Hammouda, Man-Ho Kim
Small-angle scattering requires models to analyze the data. A core-chain model has been available to fit data from solutions of core-chain particles. When the core particles are "hard" with well-defined surface, that model has been found to work well and

The Open Academic Robot Kit

July 12, 2017
Author(s)
Raymond K. Sheh, Amy Eguchi, Haldun Komsuoglu, Adam Jacoff
The Open Academic Robot Kit (OARKit) lowers the barrier of entry into robotics research. A community driven initiative, it was developed in the context of the RoboCupRescue Robot League competition to advance the state of research in response robotics. All

VMEXT: A Visualization Tool for Mathematical Expression Trees

July 12, 2017
Author(s)
Moritz Schubotz, Howard Cohl, Bela Gipp, Norman Meuschke, Thomas Hepp
Mathematical expressions can be represented as a tree consisting of terminal symbols, such as identifiers or numbers (leaf nodes), and functions or operators (non-leaf nodes). Expression trees are an important concept to store and process mathematical

Calibration of night vision goggles: an SI-units-based measurement technique

July 11, 2017
Author(s)
Vyacheslav B. Podobedov, George P. Eppeldauer, Thomas C. Larason
A new night vision goggles (NVG) gain definition for the calibration process is proposed and evaluated. This definition is based on the radiance measurements at the input and output of the NVG. In contrast to the old definition which uses a non-

Color Quality (book chapter)

July 11, 2017
Author(s)
Yoshihiro Ohno
This book chapter provides the fundamentals of colorimetry and color quality for solid state lighting, including descriptions of the current standards on chromaticity of SSL light sources and color rendering, and recent studies on these topics. Section 8.1

Enhancing Egress Drills: Preparation and Assessment of Evacuee Performance

July 11, 2017
Author(s)
Steve Gwynne, Erica D. Kuligowski, Karen E. Boyce, Daniel Nilsson, Amanda Robbins, Ruggiero Lovreglio, J.R. Thomas, A. Roy-Poirier
This article explores how egress drills - specifically those related to fire incidents - are currently employed, their impact on safety levels, and the insights gained from them. It is suggested that neither the merits of egress drills are well understood

SATE VI Ockham Sound Analysis Criteria

July 11, 2017
Author(s)
Paul E. Black
In preparation for SATE VI, we present our current thoughts on the Ockham Sound Analysis Criteria track. First, we explain the purpose of the Ockham track and define some terms, such as "sound", "finding", and "site". Then we present the general flow for

Development of NIST Standard Reference Material 2082, a Pathlength Standard for Measurements in the Ultraviolet Spectrum

July 10, 2017
Author(s)
Brian Lang, Aaron A. Urbas, Paul C. DeRose, Hung-Kung Liu, John C. Travis, Steven J. Choquette, Kenneth D. Cole
New spectrophotometers and cuvettes have been designed to allow the measurement of absorbance values from samples using microliter volume sizes. These measurements are done using short pathlengths to decrease the sample volumes required. The major

Equivalent Isotropic Response as a Surrogate for Incident Field Strength

July 9, 2017
Author(s)
Dan Kuester, Duncan McGillivray, William F. Young, John M. Ladbury, Ari Feldman, Adam Wunderlich, Sheryl M. Genco
The strength of a radiated field at some location in free space can be described in terms of the equivalent conducted output from an isotropic probe antenna with a specified reference polarization. This metric has already entered use by various standards

Seasonal variation of total mercury burden in the American alligator (Alligator mississippiensis) at Merritt Island National Wildlife Refuge (MINWR), Florida

July 8, 2017
Author(s)
Frances Nilsen, Jonathan E. Dorsey, Stephen E. Long, Tracey B. Schock, John A. Bowden, Russell H. Lowers, Louis J. Guillette Jr.
Seasonal variation of mercury (Hg) is not well studied in free-ranging wildlife. Atmospheric deposition patterns of Hg have been studied in detail and have been modeled for both global and specific locations with great accuracy and correlates to

Formation of [Cu 2 O 2 ] 2+ and [Cu 2 O] 2+ Toward C-H Bond Activation in Cu-SSZ-13 and Cu-SSZ-39

July 7, 2017
Author(s)
Bahar Ipek, Matthew J. Wulfers, Hacksung Kim, Florian Goeltl, Ive Hermans, Joseph P. Smith, Karl S. Booksh, Craig Brown, Raul F. Lobo
Cu- exchanged small-pore zeolites (CHA and AEI) form methanol from methane (>95% selectivity) using a 3-step cyclic procedure (Wulfers, M. J.; Teketel, S.; Ipek, B.; Lobo, R. F. Chem. Commun. 2015, 51, 4447–4450) with methanol amounts higher than Cu- ZSM-5

In Situ Carbon Dioxide and Methane Measurements from the Los Angeles Megacity Carbon Project

July 7, 2017
Author(s)
Kristal R. Verhulst, Anna Karion, Jooil Kim, Peter Salameh, Chris Sloop, Ralph Keeling, Ray Weiss, Riley Duren, John B. Miller
Concern about rising greenhouse gas levels has motivated many nations to begin mitigating emissions, motivating the need for robust, consistent, traceable greenhouse gas observation methods in complex urban domains. The Los Angeles (LA) Megacity Carbon

Photochemical Properties of CH2=CH-CFCl-CF2Br (4-bromo-3-chloro-3,4,4-trifluoro-1-butene) and CH3-O-CH-(CF3)2 (methyl 2,2,2-trifluoroethyl-1-trifluoromethyl ether): OH Reaction Rate Constant, UV and IR Absorption Spectra.

Rana NMN Ashkar, Michael J. A. Hore, Xingchen Ye, Bharath NMN Natarajan, Nicholas J. Greybush, Thomas Lam, Christopher B. Murray
The utility of gold nanorods for plasmonic applications largely depends on the relative orientation and proximity of the nanorods within a material. Through previous studies have demonstrated methods that can generate side-by-side or chain-like nanorod
