Dielectric properties of Nb_x}W_1-x}Se_2} alloys

December 16, 2019
Author(s)
Albert Rigosi, Heather M. Hill, Sergiy Krylyuk, Nhan V. Nguyen, Angela Hight Walker, Albert Davydov, David Newell
The growth of transition metal dichalcogenide (TMDC) alloys provides an opportunity to experimentally access information elucidating how optical properties change with gradual substitutions in the lattice compared with their pure compositions. In this work

Economics of Interoperability in the Context of Smart Grid Architectures

December 16, 2019
Author(s)
Cheyney O'Fallon, Avi Gopstein
Technological change in the electric power sector has progressed rapidly and there now is need for the development and evaluation of new smart grid architectures. This special publication discusses the current conditions of the U.S. electric grid and the

Measurement of Airborne Emissions from Extinguished Cigarettes: Final Report

December 16, 2019
Author(s)
Dustin G. Poppendieck
Three series of experiments were conducted in this study. First, studies were performed to the determine the relative distributions of the target chemicals in freshly smoked butts by analyzing six types of samples consisting of different parts of the butts

Numerical methods every atomic and molecular theorist should know

December 16, 2019
Author(s)
Barry I. Schneider, Heman Gharibnejad
This review article discusses a few theoretical and numerical approaches that have been successfully used to treat electron scattering and photoionization of atoms and molecules and the interaction of those systems with intense, short-pulse electromagnetic

Enhancing LAA Co-existence Using MIMO Under Imperfect Sensing

December 13, 2019
Author(s)
Somayeh Mosleh, Yao Ma, Jason B. Coder, Erik Perrins, Lingjia Liu
To meet the ever growing wireless network demands, in terms of subscribers and data throughput, operating long term evolution (LTE) in unlicensed bands, also known as license assisted access (LAA), is introduced as a promising solution. However, the LAA

Reduced Holey Graphene Oxide Membranes for Desalination with Improved Water Permeance

December 13, 2019
Author(s)
Xiaoyi Chen, Zhihao Feng, Janavi Gohil, Christopher Stafford, Ning Dai, Liang Huang, Haiqing Lin
Reduced-graphene oxide (r-GO) membranes with narrow channels exhibit salt rejections comparable to conventional nanofiltration (NF) membranes. However, their water permeances are much lower because of the high tortuosity for water permeation. Herein we

Verifying the Performance of a Correlation-Based Channel Sounder in the 3.5 GHz Band with a Calibrated Vector Network Analyzer

December 12, 2019
Author(s)
Jeffrey A. Jargon, Jeanne T. Quimby, Catherine A. Remley, Amanda A. Koepke, Dylan F. Williams
We verified the performance of a correlation-based channel sounder in the 3.5 GHz band with a calibrated vector network analyzer by comparing measurements in a stable, coaxial environment at the same reference planes. The purpose of this experiment was to

A Strategy for Handling Aberration in Spherical Neutron Polarimetry

December 11, 2019
Author(s)
Jacob Tosado, Wangchun Chen, Efrain E. Rodriguez
We present a strategy for identifying and correcting for aberration effects in Spherical Neutron Polarimetry. The transformation of the neutron beam polarization vector due to scattering from a material is determined with Spherical Neutron Polarimetry

DIGITAL TWIN FOR SMART MANUFACTURING: THE SIMULATION ASPECT

December 11, 2019
Author(s)
Guodong Shao, Sanjay Jain, Christoph Laroque, Loo Hay Lee, Peter Lendermann, Oliver Rose
The purpose of this panel is to discuss the state of the art in digital twin for manufacturing research and practice from the perspective of the simulation community. The panelists come from the US, Europe, and Asia representing academia, industry, and

Emergent Magnetic State in (111)-Oriented Quasi-Two-Dimensional Spinel Oxides

December 11, 2019
Author(s)
Xiaoran Liu, Sobhit Singh, Brian Kirby, Zhicheng Zhong, Yanwei Cao, Banabir Pal, Mikhail Kareev, Srimanta Middey, John W. Freeland, Padraic Shafer, Elke Arenholz, David Vanderbilt, Jak Chakhalian
We report on the emergent magnetic state of (111)-oriented CoCr 2O 4 ultrathin films sandwiched by Al 2O 3 in the quantum confined geometry. At the two-dimensional crossover, polarized neutron reflectometry reveals an anomalous enhancement of the total

NIST Special Database 302: Nail to Nail Fingerprint Challenge

December 11, 2019
Author(s)
Gregory P. Fiumara, Patricia A. Flanagan, John D. Grantham, Kenneth Ko, Karen Marshall, Matthew Schwarz, Elham Tabassi, Bryan Woodgate, Christopher Boehnen
In September 2017, the Intelligence Advanced Research Projects Activity (IARPA) held a data collection as part of its Nail to Nail (N2N) Fingerprint Challenge. Participating Challengers deployed devices designed to collect an image of the full nail to nail

On the Cooling of a 360o Video Camera to Observe Fire Dynamics In Situ

December 11, 2019
Author(s)
Jiann C. Yang
An analysis was performed to provide design guidance on the cooling of an NIST-developed in situ fire visualization device, called Burn Observation Bubble (BOB). The analysis was to address the question of how long the device can be operated in a fire

Sizing up the Next Generation of Nanomedicines

December 11, 2019
Author(s)
Jeffrey D. Clogston, Vincent A. Hackley, Adriele Prina-Mello, Sanyogitta Puri, Silvia Sonzini, Patrick Lim Soo
During the past two decades the field of nanomedicines has experienced significant progress. To date, over sixty nanoparticle (NP) formulations have been approved in the US and EU while many others are in clinical or preclinical development, indicating a

The Economics of Firefighter Injuries in the United States

December 11, 2019
Author(s)
David T. Butry, David H. Webb, Stanley W. Gilbert, Jennifer Taylor
This report identifies, summarizes, and evaluates the available data and the literature describing the economic costs associated with non-fatal firefighter injuries, illnesses, health exposures, and occupational disease (‘health outcomes’) resulting from

Generating few-cycle pulses with integrated nonlinear photonics

December 10, 2019
Author(s)
David Carlson, Phillips Hutchison, Daniel D. Hickstein, Scott Papp
Ultrashort laser pulses that last only a few optical cycles have been transformative tools for studying and manipulating ultrafast light--matter interactions. These few-cycle pulses are typically produced from high-peak-power lasers, either directly from
