A Hybrid Wired/Wireless Deterministic Network for Smart Grid

July 26, 2021
Author(s)
Bin Hu, Hamid Gharavi
With the rapid growth of time-critical applications in smart grid, robotics, autonomous vehicles, and industrial automation, demand for high reliability, low latency and strictly bounded jitter is sharply increasing. High-precision time synchronization

Layered Double Perovskites

July 26, 2021
Author(s)
Hayden Evans, Lingling Mao, Ram Seshadri, Anthony K. Cheetham
Successful strategies for the design of crystalline materials with useful function are frequently based on the systematic tuning of chemical composition within a given structural family. Perovskites with the formula ABX 3, perhaps the best-known example of

Promoting Persistent Superionic Conductivity in Sodium Monocarba-closo-dodecaborate NaCB11H12 via Confinement within Nanoporous Silica

July 26, 2021
Author(s)
Mikael Andersson, Vitalie Stavila, Alexander V. Skripov, Mirjana Dimitrievska, Malgorzata T. Psurek, Juscelino Leao, Olga Babanova, Roman Skoryunov, Alexei Soloninin, Maths Karlsson, Terrence J. Udovic
Superionic phases of bulk anhydrous salts based on large cluster-like polyhedral (carba)borate anions are generally stable only well above room temperature, rendering them unsuitable as solid-state electrolytes in energy-storage devices that typically

Real-Time Low-Frequency Oscillations Monitoring

July 26, 2021
Author(s)
Bin Hu, Hamid Gharavi
A major concern for interconnected power grid systems is low frequency oscillation, which limits the scalability and transmission capacity of power systems. Un-damped, or poorly-damped oscillations will lead to undesirable conditions or even a catastrophic

Programmable System on Chip for controlling an atomic physics experiment

July 23, 2021
Author(s)
Ananya Sitaram, Gretchen K. Campbell, Alessandro Restelli
Most atomic physics experiments are controlled by a digital pattern generator used to synchronize all equipment by providing triggers and clocks. Recently, the availability of well-documented open-source development tools has lifted the barriers to using

Review of the Advanced Encryption Standard

July 23, 2021
Author(s)
Nicky Mouha, Morris Dworkin
The field of cryptography continues to advance at a very rapid pace, leading to new insights that may impact the security properties of cryptographic algorithms. The Crypto Publication Review Board ("the Board") has been established to identify

Atom probe tomography

July 22, 2021
Author(s)
Ann Chiaramonti Debay, Baptiste Gault, Julie Cairney, Michael P. Moody, Oana Cojocaru-Miredin, Patrick Stender, Renelle Dubosq, Christoph Freysoldt, Surendra Kumar Makineni, Tong Li
Atom probe tomography (APT) provides three-dimensional compositional mapping with sub-nanometre resolution. The sensitivity of APT is in the range of parts per million for all elements, including light elements such as hydrogen, carbon or lithium, enabling

Neutron Scattering Investigations of the Global and Local Structures of Ammine Yttrium Borohydrides

July 22, 2021
Author(s)
Jakob Grinderslev, Mikael S. Andersson, Benjamin Trump, Wei Zhou, Terrence J. Udovic, Maths Karlsson, Torben Jensen
Complex metal hydrides are a fascinating and continuously expanding class of materials with many properties relevant for solid-state hydrogen and ammonia storage and solid state electrolytes. The crystal structures are often investigated using powder X-ray

Simulated filament shapes in embedded 3D printing

July 22, 2021
Author(s)
Leanne Friedrich, Jonathan Seppala
Embedded 3D printing, wherein fluid inks are extruded into a bath, has enabled the manufacture of complex, custom structures ranging from cell-laden tissue analogues to soft robotics. This method encompasses two techniques: embedded ink writing (EIW)

Comparison Demonstrates Factor of Three Improvement in Gas Flow Measurements

July 21, 2021
Author(s)
John D. Wright, Gina Kline, Kevin John, Brian Novitsky, Jason Bellavance, Kevin SHufelt, Bradley Nease, Miles Owen, Joseph Allen, Casey Rombouts, William Gause, John Cuccio
A comparison of seven gas flow calibration laboratories piloted by NIST used four laminar flow meters as the transfer standards for nine nitrogen gas flows ranging from 1 sccm to 10 slm. The comparison reference value was calculated from the uncertainty

Fluorescence Microscopy Reveals Structure-Property Relationships and Polymer Dynamics in Biocomposites

July 21, 2021
Author(s)
Quinn Easter, Shawn Chen, Jeremiah Woodcock, Amanda Souna, Sindhu Seethamraju, Jan Obrzut, Douglas M. Fox, Stephan J. Stranick, Jeffrey Gilman
OBJECTIVES: Developing the next generation of materials for use in restorative work requires a multifaceted approach. While mimicking the properties of the tooth, currently available dental composites and porcelains eventually fail and require replacement

Author(s)
Bradley Moore, John Matyjas, Raymond Tierney, Jesse Angle, Jeannine Abiva, Jeff Hanes, David Dobosh, John Avera
NIST Handbook 150-872 presents the technical requirements and guidance for the accreditation of laboratories under the National Voluntary Laboratory Accreditation Program (NVLAP) Federal Warfare System(s) (FWS) program. It is intended for information and

Resource optimization of quantum-enabled channels using novel modulation schemes

July 21, 2021
Author(s)
Jabir Marakkarakath Vadakkepurayil, FNU Nur Fajar Rizqi Annafianto, Ivan Burenkov, Abdella Battou, Sergey Polyakov
We introduce new practical modulation schemes inspired by the quantum measurement. We experimentally show that our quantum-enabled communication system optimizes the combined resource efficiency (CRE) beyond the classical, shot-noise-limited CRE.

Binary Diffusion Coefficients for Fluorocarbons in Nitrogen

Author(s)
William Sean McGivern, Jeffrey A. Manion
Binary gas-phase diffusion coefficients, of interest in physical models of atmospheric and combustion chemistry, have been measured in N2 for the homologous series of refrigerant-related (fluoro)methanes CH4, CH3F, CH2F2, and CHF3. Values have been
