H2 Production in the 10B(n,?)7Li Reaction in Water

December 4, 2020
Author(s)
Alan K. Thompson, Travis C. Dietz, Mohamad Al-Sheikhly, Marcin Sterniczuk, David M. Bartels
We demonstrate a method for measuring the H2 produced in water from the 10B(n,α)7Li fission reaction. Low energy neutrons from the NIST Center for Neutron Research interact with borate- containing water in a temperature-controlled high pressure cell made

Improved coupled-mode theory for high-index-contrast photonic platforms

December 4, 2020
Author(s)
Qing Li, Gregory Moille, Hossein Taheri, Ali Adibi, Kartik Srinivasan
Coupled-mode theory has been widely used in optics and photonics design. Despite its popularity, several different formulations of coupled-mode theory exist in the literature and their applicable range is not entirely clear, in particular when it comes to

Integrative Method to Whole-House Energy and Comfort Rating

December 4, 2020
Author(s)
Hyojin Kim, Han Yan, Anuradha Kadam
The purpose of this research is to investigate how thermal comfort dynamics are impacted by energy-efficient or thermal comfort improvements in a low-load house and to explore methods or metrics to rate a whole-house performance in an integrative way based

Mission Critical Voice Quality of Experience Access Time Measurement Method Addendum

December 1, 2020
Author(s)
Chelsea Greene, Jesse Frey, Zainab O. Soetan, Jaden Pieper, Silas Thompson
Access time generally describes the time associated with the establishment of a talk path upon user request to speak and has been identified as a key component of quality of experience (QoE) in voice communications. The National Institute of Standards and

Probing Electrified Liquid-Solid Interfaces with Scanning Electron Microscopy

December 2, 2020
Author(s)
Hongxuan Guo, Alexander Yulaev, Evgheni Strelcov, Alexander Tselev, Christopher M. Arble, Andras Vladar, John S. Villarrubia, Andrei Kolmakov
The mean free path of secondary electrons in aqueous solutions is on the order of a nanometer, making them a suitable probe of ultrathin electrical double layers at solid-liquid electrolyte interfaces. Employing graphene as an electron-transparent

Simplify your life

December 2, 2020
Author(s)
Gordon Drake, Eite Tiesinga
Within the Hartree atomic unit systems, the Schrödinger equation becomes parameter free. But there's more to it than making a student's life easier, as Gordon Drake and Eite Tiesinga recount.

An Approach for Detection of Advanced Persistent Threat Attacks

December 1, 2020
Author(s)
Qingtian Zou, Xiaoyan Sun, Peng Liu, Anoop Singhal
Advanced Persistent Threat (APT) campaigns employ sophisticated strategies and tactics to achieve their attack goal. The evolution of APT strategies and tactics compounds the challenge of detecting attack campaigns. This article introduces an approach

Annotated Bibliography of Key Publications on Business and Economic Recovery from Disasters

December 1, 2020
Author(s)
Sahar Derakhshan, Juri Kim, Maria Watson, Stephanie Chang, Charolotte Brown, Noah Dormandy, John Handmer, Jennifer Helgeson, Yoshio Kajitani, Adriana Keating, Ilan Noy, Adam Rose, Anne Wein, Norihiko Yamano
This Working Group focuses on the economic recovery of businesses and economies from the COVID-19 pandemic. With communities around the world experiencing severe economic impacts, we anticipate a proliferation of efforts to track, assess, and explain local

Exchange Bias Switching in an Antiferromagnet/Ferromagnet Bilayer Driven by Spin-Orbit Torque

December 1, 2020
Author(s)
Shouzhong Peng, Daoqian Zhu, Weixiang Li, Hao Wu, Alexander Grutter, Dustin A. Gilbert, Jiaqi Lu, Danrong Xiong, Wenlong Cai, Padraic Shafer, Kang L. Wang, Weisheng Zhao
Electrical manipulation of exchange bias and magnetization in antiferromagnet/ferromagnet thin films has been of great interest in recent years. Here, we experimentally demonstrate current-induced switching of exchange bias in perpendicularly magnetized

Methods for Characterization of Bioactivity Using Confocal Microscopy

December 1, 2020
Author(s)
Jirun Sun, Nancy Lin, Joy Dunkers, Sheng Lin-Gibson
One common tissue engineering approach for regenerating or replacing damaged tissues involves a porous polymeric scaffold. The scaffolds serve as the mechanical framework for cell attachment and growth, and generate an environment with features that span

Temporal Memory with Magnetic Racetracks

December 1, 2020
Author(s)
Hamed Vakili, Mohammed N. Sakib, Samiran Ganguly, Mircea Stan, Matthew Daniels, Advait Madhavan, Mark D. Stiles, Avik W. Ghosh
Race logic is a relative timing code that represents information in a wavefront of digital edges on a set of wires in order to accelerate dynamic programming and machine learning algorithms. Skyrmions, bubbles, and domain walls are mobile magnetic

A low-swelling, polymeric mixed conductor operating in aqueous electrolytes

November 30, 2020
Author(s)
Lee J. Richter, Tommaso Nicolini, Jokubas Surgailis, Achileas Savva, Guillaume Wantz, Olivier Dautel, Georges Hadiziioannou, Natalie Stingelin
Organic mixed conductors find use in batteries, bioelectronics technologies, neuromorphic computing and sensing. While great progress has been achieved, polymer-based mixed conductors frequently experience significant volumetric changes during ion uptake

Numerical Evaluation of Advanced Laser Control Strategies Influence on Residual Stresses for Laser Powder Bed Fusion Systems

November 30, 2020
Author(s)
Carraturo Massimo, Brandon Lane, Ho Yeung, Stefan Kollmannsberger, Alessandro Reali, Ferdinando Auricchio
Process-dependent residual stresses are one of the main burdens to a wide spread adoption of laser powder bed fusion technology in industry. Residual stresses are directly influenced by process parameters, such as laser path, laser power, and speed. In
