Mechanisms for carbon adsorption on Au(110)-(2 x 1): A work function analysis

July 17, 2018
Author(s)
Dustin A. Hite, Hossein Jooya, Kyle S. McKay, Eunja Kim, Philippe F. Weck, David P. Pappas, H.R. Sadeghpour
The variation of the work function upon carbon adsorption on the reconstructed Au(110) surface is measured experimentally and compared to density functional calculations. The adsorption dynamics is simulated with ab-initio molecular dynamics techniques

Effect of temperature on the structure and dynamics of triblock copolymer coacervate hydrogels

July 16, 2018
Author(s)
Vivek M. Prabhu, Ryan C. Nieuwendaal, Anand Rahalkar, Juan J. DePablo, Samanvaya Srivastava, Matthew Tirrell
Triblock copolymer coacervate gels were characterized by small-angle neutron scattering (SANS) and dynamic light scattering. The oppositely charged polyelectrolyte complex core size does not change with temperature. However, the neutral middle block that

Energy-level statistics in strongly disordered systems with power-law hopping

July 16, 2018
Author(s)
Paraj T. Bhattacharjee, Victor L. Quito, Sergey V. Syzranov
Motivated by neutral excitations in disordered electronic materials and systems of trapped ultracold particles with long-range interactions, we study energy-level statistics of quasiparticles with the power-law hopping Hamiltonian $\propto 1/r^\alpha$ in a

Kinetic Mechanism of 2,3,3,3-Tetrafluoropropene (HFO-1234yf) Combustion

July 16, 2018
Author(s)
Valeri I. Babushok, Gregory T. Linteris
A kinetic model for 2,3,3,3-tetrafluoropropene (HFO-1234yf) high temperature oxidation and combustion is proposed. It is combined with the GRI-Mech-3.0 model, with the previously developed model for 2-bromo-3,3,3-trifluoropropene (2-BTP), and with the NIST

Quantifying Wind-Driven Firebrand Production from Roofing Assembly Combustion

July 16, 2018
Author(s)
Samuel L. Manzello, Sayaka Suzuki, Tomohiro Naruse
Large outdoor fires present a risk to the built environment. Examples often in the international media reports are wildfires that spread into communities, referred to as Wildland-Urban Interface (WUI) fires. Other examples are large urban fires including

Robotic Grasping and Manipulation Competition: Task Pool

July 15, 2018
Author(s)
Yu Sun, Joseph Falco, Nadia Cheng, Hyouk Ryeol Choi, Erik Engeberg, Nancy Pollard, Maximo Roa, Zeyang Xia
A Robot Grasping and Manipulation Competition was held during IROS 2016. The competition provided a common set of robot tasks for researchers focused on the application of robot systems to compare the performance of hand designs as well as autonomous

THREE APPROACHES TO QUANTIFICATION OF NDE UNCERTAINTY AND A DETAILED EXPOSITION OF THE EXPERT PANEL APPROACH USING THE SHEFFIELD ELICITATION FRAMEWORK

July 15, 2018
Author(s)
Jeffrey T. Fong, Nathanael A. Heckert, James J. Filliben, Steven R. Doctor
The ASME Boiler & Pressure Vessel Code Section XI Committee is currently developing a new Division 2 nuclear code entitled the "Reliability and Integrity Management (RIM) program," with which one is able to arrive at a risk-informed, NDE-based engineering

User Context: An Explanatory Variable in Phishing Susceptibility

July 15, 2018
Author(s)
Kristen K. Greene, Michelle P. Steves, Mary Theofanos, Jennifer A. Kostick
Extensive research has been performed to examine the effectiveness of phishing defenses, but much of this research was performed in laboratory settings. In contrast, this work presents 4.5 years of workplace-situated, embedded phishing email training

IR Computer Generated Holograms: Design and Application for the WFIRST Grism using Wavelength-Tuning Interferometry

July 14, 2018
Author(s)
Margaret Z. Dominguez, Catherine Marx, Qian Gong, John Hagopian, Ulf Griesmann, James Burge, Dae Wook Kim
Interferometers using computer generated holograms (CGHs) have become the industry standard to accurately measure aspheric optics. The CGH is a diffractive optical element that can create a phase or amplitude distribution and can be manufactured with low

Characterization of Interfacial Structure in Polymer-Fullerene Bulk Heterojunctions via 13C {2H} Rotational Echo Double Resonance NMR

July 13, 2018
Author(s)
Ryan C. Nieuwendaal, Dean M. DeLongchamp, Martin Heeney, Jan Hummelen, Chad R. Snyder, Ronald L. Jones, Sebastian Engmann, Lee J. Richter, Zhuping Fei, Alex Sieval
We introduce a new application of solid state NMR measurements towards characterizing the donor-acceptor interfaces within bulk heterojunction (BHJ) films. Rotational echo double resonance (REDOR) is used to measure dipolar couplings between 13C nuclei on

Identity and Access Management for Electric Utilities

July 13, 2018
Author(s)
James J. McCarthy
To protect power generation, transmission, and distribution, energy companies need to control physical and logical access to their resources, including buildings, equipment, information technology (IT), and operational technology (OT). They must

In IoT We Trust?

July 13, 2018
Author(s)
Jeff Voas, D. Richard Kuhn, Phillip Laplante
In this short article, we review an abbreviated list of trust challenges that we foresee as increased adoption transforms the IoT into another ubiquitous technology just as the Internet is. These challenges are in no specific order, and are by no means a

User Instructions and Technical Details for 500 mm GHP Simulation Programs

Author(s)
William C. Thomas
This report is a supplement to the paper published as "Transient Thermal Response of an Extended Temperature Range 500-mm diameter Guarded Hot-plate Apparatus" by Thomas and Zarr (2018), hereafter referred to as the "paper." The paper emphasizes the use of

Nature of Decahydro-Closo-Decaborate Anion Reorientations in an Ordered Alkali-Metal Salt: Rb 2 B 10 H 10
