Fully self-referenced frequency comb consuming 5 Watts of electrical power

September 12, 2018

Author(s)

Paritosh Manurkar, Edgar F. Perez, Daniel D. Hickstein, David R. Carlson, Jeffrey T. Chiles, Daron A. Westly, Esther Baumann, Scott A. Diddams, Nathan R. Newbury, Kartik A. Srinivasan, Scott B. Papp, Ian R. Coddington

We present a hybrid fiber/waveguide design for a 100-MHz frequency comb that is fully self- referenced and temperature controlled with less than 5 W of electrical power. Self-referencing is achieved by supercontinuum generation in a silicon nitride

Monte Carlo Simulation of Cylinders with Short-Range Attractions

September 12, 2018

Author(s)

Harold W. Hatch, Nathan Mahynski, R. P. Murphy, Marco Blanco, Vincent K. Shen

Cylindrical or rod-like particles are promising materials for the applications of fillers in nanocomposite ma- terials and additives to control rheological properties of colloidal suspensions. Recent advances in particle synthesis allows for cylinders to

Polymer Identification of Plastic Debris Ingested by Pelagic-phase Sea Turtles in the Central Pacific

September 12, 2018

Author(s)

Melissa R. Jung, George H. Balazs, Thierry M. Work, T. T. Jones, Sara Orski, Viviana Rodriguez, Kathryn Beers, S. A. Abriola, K. D. Hyrenbach, Brenda A. Jensen, Jennifer Lynch

Pelagic Pacific sea turtles eat large quantities of plastic. We identified the polymers ingested by 37 olive ridley, 9 green and 4 loggerhead sea turtles caught as bycatch in Pacific longline fisheries using Fourier transform infrared spectroscopy

Spherical Test Objects for Hand-held Metal Detector Characterization

September 12, 2018

Author(s)

Nicholas G. Paulter Jr., Donald R. Larson, John A. Ely

Measuring the detection performance of metal detectors (hand-worn, hand-held, and walk-through models) is based on the observation of an alarm indication (light, sound, vibration) given by the metal detector when a threat or test object is present. These

A Novel Application of Silicone-Based Flame-Retardant Adhesive in Plywood

September 11, 2018

Author(s)

Mauro Zammarano, John R. Shields, Elizabeth D. Knowlton, Ickchan Kim, Matthew S. Hoehler

A silicone-based elastomer filled with vinyl-silane treated aluminum hydroxide was used as a flame- retardant adhesive for plywood, as a replacement for a conventional polyurethane-based adhesive. The shear strength and fire performance of such a silicone

Core-Shell p-i-n GaN Nanowire LEDs by N-polar Selective Area Growth

September 11, 2018

Author(s)

Matthew D. Brubaker, Kristen L. Genter, Bryan T. Spann, Alexana Roshko, Paul T. Blanchard, Todd E. Harvey, Kristine A. Bertness

GaN nanowire LEDs with radial p-i-n junctions were grown by molecular beam epitaxy using N- polar selective area growth on Si(111) substrates. The N-polar selective area growth process facilitated the growth of isolated and high-aspect-ratio n-type NW

Extending Portico HLA to Federations of Federations with Transport Layer Security

September 11, 2018

Author(s)

Thomas Roth, Martin Burns, Tim Pokorny

The Internet of Things (IoT) promises to connect and manage an unprecedented number of heterogeneous devices that are not designed to interoperate as a system. Modeling and Simulation of IoT will face new challenges in the representation of this scale

Fundamentals and characterizations of scratch resistance on automotive clearcoats

September 11, 2018

Author(s)

Li Piin Sung, Linqian Feng, Nadia Benhamida, Pierre Morel, Andrew T. Detwiler, Jon M. Skelly, Leslie T. Baker, Deepanjan Bhattacharya

As original equipment manufacturers (OEMs) strive to deliver improved coating performance with a sustainable footprint, opportunities for innovation are emerging, particularly on improving mechanical properties, appearance, and solids content. Resistance

Proceedings of the First Workshop Organized by the IAFSS Working Group on Measurement and Computation of Fire Phenomena (MaCFP)

September 11, 2018

Author(s)

Randall J. McDermott, Morgan Bruns

This paper provides a report of the discussions held at the first workshop on Measurement and Computation of Fire Phenomena (MaCFP) on June 10-11 2017. The first MaCFP workshop was both a technical meeting for the gas phase subgroup and a planning meeting

Quantification of Carbon Nanotube Liquid Crystal Morphology via Neutron Scattering

September 11, 2018

Author(s)

Francesca Mirri, Rana N. Ashkar, Vida Jamali, Lucy Liberman, Robert A. Pinnick, Paul van der Schoot, Yeshayahu Talmon, Paul Butler, Matteo Pasquali

Liquid phase assembly is among the most industrially attractive routes for scalable carbon nanotube (CNT) processing. Chlorosulfonic acid (CSA) was found to be an ideal solvent for CNTs, spontaneously dissolving them without compromising their properties

Reference Materials and Proficiency Testing for Validating X-Ray Powder Diffraction Measurements of Cement Composition

September 11, 2018

Author(s)

Paul E. Stutzman

Validation of quantitative X-ray powder diffraction measurements traditionally involved compounding test mixtures of known phase compositions. Validation is particularly important with the Rietveld method as the normalization will obscure bias. ASTM C1365
