Ultrafast Optical Pulse Shaping using Dielectric Metasurfaces

May 2, 2019
Author(s)
Shawn M. Divitt, Wenqi Zhu, Cheng Zhang, Henri Lezec, Amit Agrawal
Simultaneous control of individual frequency-comb lines, and their modulation at the repetition-rate of an ultrafast laser represents the ultimate limit of optical pulse shaping. Remarkable progress in mode-locked lasers and chirped pulse amplifiers

Using Symmetry To Elucidate the Role Of Stoichiometry In Colloidal Crystal Assembly

May 2, 2019
Author(s)
Nathan Mahynski, Evan Pretti, Vincent K. Shen, Jeetain Mittal
We demonstrate a method based on symmetry to predict the structure of multi-component colloidal mixtures. In this work we focus on two-dimensional systems, for which the method allows us to exhaustively enumerate candidates from all wallpaper groups

Direct Measurement of Hydrogen Diffusivity and Solubility Limits in Zircaloy 2 (Formula Unit of ZrH 0.0155 ) using Incoherent Quasi-Elastic Neutron Scattering

May 1, 2019
Author(s)
Brent J. Heuser, Timothy R Prisk, Jun-li Lin, Tanya J. Dax, Yongfeng Zhang
The diffusivity of hydrogen is an important property of light water nuclear reactor (LWR) fuel cladding. LWR cladding absorbs hydrogen during normal operation, a contributing factor to embrittlement that decreases the lifetime of the fuel. Mass transport

Environmental Friendly Flame Resistant Coatings for Soft Furnishing

May 1, 2019
Author(s)
Yeon S. Kim, Yu-Chin Li, John R. Shields, Rick D. Davis
Pending flammability regulations and scrutinizing of the environment and health consequences of fire retardants is creating opportunities for novel and “greener” technologies to reduce the flammability of residential furniture. This presentation will

Grain Orientation Mapping of Graphene in a Scanning Electron Microscope

May 1, 2019
Author(s)
Benjamin W. Caplins, Jason D. Holm, Robert R. Keller
A scanning transmission electron diffraction method is developed for use in the scanning electron microscope to perform orientational imaging microscopy of 2D materials. The method can generate grain orientational maps of monolayer graphene over a field of

Guidelines for Generating Public Safety Benchmark Scenario Set

May 1, 2019
Author(s)
Richard A. Rouil, Chunmei Liu, Antonio Izquierdo Manzanares
There is a need to establish well-defined, public safety scenarios for the evaluation of current and future communication technologies for first responders. The scenario descriptions must contain enough details to be considered representative of key public

Proceedings of the 9th Model-Based Enterprise Summit (MBE 2018)

May 1, 2019
Author(s)
Thomas D. Hedberg, Mark G. Carlisle
The ninth installment of the Model-Based Enterprise (MBE) Summit was hosted at the National Institute of Standards and Technology (NIST) on April 2-5, 2018. The MBE Summit 2018 witnessed another year-over-year registration growth. This speaks to the

Rattling Behavior in a Simple Perovskite NaWO 3

May 1, 2019
Author(s)
Yuya Ikeuchi, Hiroshi Takatsu, Cedric Tassel, Craig Brown, Taito Murakami, Yuki Matsumoto, Yoshihiko Okamoto, Hiroshi Kageyama
A high-pressure reaction has allowed the preparation of stoichiometric tungsten bronze NaWO 3 (Im-3). Specific heat (C ;/T 3 vs T) exhibits a round peak at 30 K, indicating anharmonic phonon modes associated with low-energy rattling vibrations. Structural

Reference Material 8634: Ethylene Tetrafluoroethylene for Particle Size Distribution and Morphology

May 1, 2019
Author(s)
Dean C. Ripple, Srivalli Telikepalli, Kristen L. Steffens, Michael J. Carrier, Christopher B. Montgomery, Nicholas W. Ritchie, John Lu
Reference Material (RM) 8634 is a NIST particle standard produced from abraded ethylene tetrafluoroethylene (ETFE), a chemically inert polymer, that will help standardize and allow more accurate monitoring of subvisible proteinaceous particles in
