A 3D PRINTING FLEXURE PRESSURE SENSOR FOR ROBOT IMPACT SAFETY TESTING

October 9, 2015
Author(s)
Hongliang Shi, Yong Sik Kim, Nicholas G. Dagalakis, Duan Xuechao
This paper presents a flexure pressure sensor fabricated by means of 3D printing. This sensor combined with a biosimulant artifact from National Institute of Standards and Technology (NIST) is used to measure the severity of injuries caused in the case of

A Scanning Probe Investigation of the Role of Surface Motifs in the Behavior of p-WSe(sub2) Photocathodes

Author(s)
Jesus M. Velazquez, Jimmy John, Daniel V. Esposito, Adam Pieterick, Ragip Pala, Guofeng Sun, Xinghao Zhou, Zhuangqun Huang, Shane Ardo, Bruce S. Brunschwig, Nathan S. Lewis
The spatial variation in the properties and performance of bare and Pt-decorated p-type WSe(sub2) photocathodes has been investigated by using Scaning Photocurrent Microscopy (SPCM) and Local Spectral Response in solution. Microscale SPCM measurements

Identification and Quantification of Six-Ring C26H16 Cata-Condensed Polycyclic Aromatic Hydrocarbons in a Complex Mixture of Polycyclic Aromatic Hydrocarbons from Coal Tar

October 8, 2015
Author(s)
Jorge O. Ona Ruales, Arun K. Sharma, Stephen A. Wise
We applied a combination of normal-phase liquid chromatography (NPLC) with ultraviolet-visible spectroscopy and gas chromatography with mass spectrometry (GC/MS) for the fractionation, identification, and quantification of six ring cata-condensed C26H16

Realization of Ground-State Artificial Skyrmion Lattices at Room Temperature

October 8, 2015
Author(s)
Dustin A. Gilbert, Brian B. Maranville, Andy L. Balk, Brian J. Kirby, Peter Fischer, Daniel T. Pierce, John Unguris, Julie A. Borchers, Kai Liu
The topological nature of magnetic skyrmions deriving from broken symmetries leads to extraordinary static and dynamic properties that provide new insight in fundamental problems of magnetism and exciting potentials for exploitation in novel magnetic

Top-top internal rotation coupling in the microwave spectrum of pinacolone

October 8, 2015
Author(s)
Jon T. Hougen, Yueyue Zhao, Ha Vanh L. Nguyen, Wolfgang Stahl
The molecular beam Fourier-transform microwave spectrum of pinacolone (methyl tert-butyl ketone) has been measured in several regions between 4 and 40 GHz. Fits of the assigned spectrum using several computer programs based on different models for treating

Unparalleled Lithium and Sodium Superionic Conduction in Solid Electrolytes with Large Monovalent Cage-like Anions

October 8, 2015
Author(s)
Wan Si NMN Tang, Atsushi Unemoto, Wei Zhou, Vitalie Stavila, Motoaki Matsuo, Hui Wu, Shin-Ichi Orimo, Terrence J. Udovic
Solid electrolytes with sufficiently high conductivities and stabilities are the elusive answer to the inherent shortcomings of organic liquid electrolytes prevalent in today's rechargeable batteries. We recently revealed a novel fast-ion-conducting sodium

(NISTIR 7804-1)Technical Evaluation, Testing, and Validation of the Usability of Electronic Health Records: Empirically Based Use Cases for Validating Safety-Enhanced Usability and Guidelines for Standardization

October 7, 2015
Author(s)
Svetlana Z. Lowry, Mala Ramaiah, Emily S. Patterson, Sandra S. Prettyman, Debora Simmons, David Brick, Latkany A. Paul, Michael C. Gibbons, Sheryl L. Taylor
This document provides the empirical rationale for critical patient safety related usability guidelines for standardization and requirements for validation testing to ensure safety-enhanced design. These standardization guidelines are targeted at

Chemical Kinetics and Fire

October 7, 2015
Author(s)
Gregory T. Linteris, John Griffiths
The purpose of this chapter is to set out the principles of chemical kinetics as they apply to combustion in flames and fires. Chemical equilibrium, which was discussed in a previous chapter, deals with the final preferred state of a given set of reactants

Cosolvency and cononsolvency explained in terms of a Flory-Huggins type theory

October 7, 2015
Author(s)
Jack F. Douglas, Jacek Dudowicz, Freed Karl
Standard classic Flory-Huggins (FH) theory is employed to describe the enigmatic cosolvency and co-nonsolvency phenomena for systems of polymers dissolved in mixed solvents. In particular, phase boundaries (spinodals) are calculated for solutions of

2015 an eventful year for the Metabolomics Society

October 6, 2015
Author(s)
Dan Bearden, Ute Roessner
The Metabolomics Society again has experienced a year full of exciting events and developments. The activity of the Society reflects the growth of the metabolomics sciences with many more researchers in academic, government and industry institutions using

Degenerate Bose-Fermi mixtures of rubidium and ytterbium

October 5, 2015
Author(s)
James V. Porto, Varun Vaidya, Jiraphat Tiamsuphat, Steven Rolston
We report the first realization of a quantum degenerate mixture of bosonic $^{87}$Rb and fermionic $^{171}$Yb atoms in a hybrid optical dipole trap with a tunable, species-dependent trapping potential. $^{87}$Rb is shown to be a viable refrigerant for the

Enforcing realizability in explicit multi-component species transport

October 5, 2015
Author(s)
Randall J. McDermott, Kevin B. McGrattan, Jason Floyd
A strategy is proposed to guarantee realizability of species mass fractions in explicit time integration of the partial differential equations governing fire dynamics, which is multi-component transport problem. For a mixture of $n$ species, the

Equilibrium and stability of axisymmetric drops on a conical substrate under gravity

October 4, 2015
Author(s)
Asha K. Nurse, Sean A. Colbert-Kelly, Sam R. Coriell, Geoffrey B. McFadden
Motivated by recent investigations of toroidal tissue clusters that are observed to climb conical obstacles after self-assembly, we study a related problem of the determination of the equilibrium and stability of axisymmetric drops on a conical substrate

Microwave Rotational Spectral Study of SO2-CO

October 2, 2015
Author(s)
Francis J. Lovas, Matthew K. Sprague
The microwave spectrum of the molecular complex of sulfur dioxide (SO2) with carbon monoxide (CO) has been studied with a pulsed-beam Fourier Transform Microwave Spectrometer (FTMW) from a pair of gas samples of 1 % by volume of SO2 and CO in Ar, and

New Insights into Sequential Infiltration Synthesis

October 2, 2015
Author(s)
James Alexander Liddle, Jeffrey Elam, Mahua Biswas, Seth B. Darling, Angel Yanguas-Gil, Jonathan Emery, Alex Martinson, Paul Nealey, Tamar Segal-Peretz, Qing Peng, Jonathan P. Winterstein, Y. C. Tseng
Sequential infiltration synthesis (SIS) is a process derived from ALD in which a polymer is infused with inorganic material using sequential, self-limiting exposures to gaseous precursors. SIS can be used in lithography to harden polymer resists rendering
