Broadband Resonator-Waveguide Coupling for Efficient Extraction of Octave Spanning Microcombs

October 1, 2019
Author(s)
Gregory Moille, Qing Li, Travis Briles, Su P. Yu, Tara E. Drake, Xiyuan Lu, Ashutosh Rao, Daron Westly, Scott Papp, Kartik Srinivasan
Frequency combs spanning over an octave have been successfully demonstrated on-chip in Kerr nonlinear microresonators, thanks to their large effective nonlinearity and ability to support a suitable dispersion profile. Efficient extraction of intracavity

Feasibility Study of Compton Imaging for PGAA

October 1, 2019
Author(s)
Heather H. Chen-Mayer, Steven Brown, Hao Yang
We are developing a one-sided tomographic method for imaging prompt gamma rays, without moving the source, sample, or detector, in a standard prompt gamma activation analysis (PGAA) setting. Dual-plane pixelated CZT detectors developed from a commercial

Field-Tunable Quantum Disordered Ground State in the Triangular-Lattice Antiferromagnet NaYbO 2

October 1, 2019
Author(s)
Mitchell M. Bordelon, Eric Kenney, Chunxiao Liu, Tom Hogan, Lorenzo Posthuma, Marzieh Kavand, Yuangqi Lyu, Mark Sherwin, Nicholas Butch, Craig Brown, M. J. Graf, Leon Balents, Stephen D. Wilson
One of the simplest routes to pursuing magnets with strong quantum fluctuations that quench conventional order is via decorating a triangular lattice with antiferromagnetically coupled S=1/2 moments. As disorder and anisotropies inherent in materials

NIST Fatty Acid Quality Assurance Program 2017 Final Report

October 1, 2019
Author(s)
Bruce A. Benner Jr., Jacolin A. Murray
At the request of the National Institutes of Health’s (NIH’s) Office of Dietary Supplements (ODS) and in conjunction with the Centers for Disease Control and Prevention (CDC), in 2017 the National Institute of Standards and Technology (NIST) conducted the

Potential Use of Lightweight Aggregate (LWA) Produced from Bottom Coal Ash for Internal Curing of Concrete Systems

October 1, 2019
Author(s)
Mohammad Balapour, Weijin Zhao, Edward Garboczi, Nay Ye Oo, Sabrina Spatari, Grace Hsuan, Peter Billen, Yaghoob Farnam
This study evaluates the potential use of a novel lightweight aggregate (LWA), spherical porous reactive aggregate (SPoRA), which is produced from waste coal bottom ash, for internal curing of concrete. Engineering properties of SPoRA required for concrete

Revealing the emergence of classicality in nitrogen-vacancy centers

October 1, 2019
Author(s)
Thomas Unden, Daniel Louzon, Michael P. Zwolak, Wojciech Zurek, Fedor Jelezko
The origin of classical behavior of quantum systems is a long-standing mystery. Here, we examine a nitrogen vacancy center evolving naturally in the presence of its environment to study the proliferation of information about preferred quantum states via

Simulation of Copper Electrodeposition in Through-Hole Vias

October 1, 2019
Author(s)
Trevor M. Braun, Daniel Josell, Thomas P. Moffat, Jimmy John
Copper electrodeposition processes for filling metallized through-hole (TH) and through-silicon vias (TSV) depend on selective breakdown of a co-adsorbed polyether-chloride adlayer within the recessed surface features. In this work, a co-adsorption

The Role of Carbon Dioxide in Ventilation and IAQ Evaluation: 40 years of AIVC

October 1, 2019
Author(s)
Andrew K. Persily, William S. Dols, Steven J. Emmerich, Lisa C. Ng
The purpose of this summary is to review Air Infiltration and Ventilation Centre activities, as reflected in its publications, related to indoor carbon dioxide over the 40 years that have transpired since its creation. These activities, like most
