The persistence of smoke VOCs indoors: partitioning, surface cleaning, and air cleaning in a smoke-contaminated house

October 13, 2023
Author(s)
Jienan Li, Michael F. Link, Shubhrangshu Pandit, Marc Webb, Cholaphan Deeleepojananan, Kathryn Mayer, Lauren Garofalo, Katelyn Rediger, Dustin Poppendieck, Stephen Zimmerman, Marina Vance, Vicki Grassian, Glenn Morrison, Barbara Turpin, Delphine Farmer
Wildfires are increasing in frequency, raising concerns that smoke can permeate indoor environments and expose people to chemical air contaminants. To study smoke transformations in indoor environments and evaluate mitigation strategies, we added smoke to

Vulnerability Test Suite Generator (VTSG) Version 3

October 13, 2023
Author(s)
Paul E. Black, William Mentzer, Elizabeth Fong, Bertrand Stivalet
The Vulnerability Test Suite Generator (VTSG) Version 3 can create vast numbers of synthetic programs with and without specific flaws or vulnerabilities. Such programs are useful for measuring static analysis tools. VTSG was designed by the Software

Adaptive Pore Opening to Form Tailored Adsorption Sites in a Cooperatively Flexible Framework Enables Record Inverse Propane/Propylene Separation

October 11, 2023
Author(s)
Ryan Klein, Lukas Bingel, Arijit Halder, Marcus Carter, Benjamin Trump, Eric Bloch, Wei Zhou, Krista Walton, Craig Brown, C. McGuirk
A proposed low-energy alternative to the separation of alkanes from alkenes by energy-intensive cryogenic distillation is separation by porous adsorbents. Unfortunately, most adsorbents preferentially take up the desired, high-value major component alkene

Quantum Plexcitonic Sensing

October 11, 2023
Author(s)
Peng Zheng, Stephen Semancik, Ishan Barman
Quantum sensing is poised to deliver unparalleled performance compared to its classical counterpart. While fundamental to quantum sensing, quantum state control has been traditionally limited to extreme conditions, such as a high vacuum or an ultra-stable

A thermodynamic analysis of CLC transporter dimerization in lipid bilayers

October 10, 2023
Author(s)
Rahul Chadda, Taeho Lee, Robyn Mahoney-Kruszka, Elizabeth Kelley, Nathan Bernhardt, Priyanka Sandal, Janice Robertson
The CLC-ec1 chloride/proton antiporter is a membrane-embedded homodimer with subunits that can dissociate and associate, but the thermodynamic driving forces favor the assembled dimer at biological densities. Yet, the physical reasons for this stability

Cybersecurity Framework Profile for Liquefied Natural Gas

October 10, 2023
Author(s)
Bill Newhouse, Josephine Long, David Weitzel, Jason Warren, Michael Thompson, Chris Yates, Hillary Tran, Alicia Mink, Aurora Herriott, Tom Cottle
This document is the Cybersecurity Framework Profile developed for the Liquefied Natural Gas (LNG) industry and the subsidiary functions that support the overarching liquefaction process, transport, and distribution of LNG. The LNG Cybersecurity Framework

Mechanical Ventilation in a Residential Building Brings Outdoor NOx Indoors with Limited Implications for VOC Oxidation from NO3 Radicals

October 10, 2023
Author(s)
Michael F. Link, Jienan Li, Jenna Ditto, Han Huynh, Jie Yu, Stephen Zimmerman, Andrew Shore, Katelyn Rediger, Jonathan Abbatt, Lauren Garofalo, Delphine Farmer, Dustin Poppendieck
Energy-efficient residential building standards require the use of mechanical ventilation systems that replace indoor air with air from the outdoors. Transient outdoor pollution events can be transported indoors via the mechanical ventilation system, and

Physical Component Libraries for SysPhS Modeling and Simulation in Manufacturing

October 10, 2023
Author(s)
Charles Manion, Conrad Bock, Raphael Barbau
Computer-interpretable representations of system structure and behavior are at the center of developing today's complex systems. Systems engineers create and review these representations using graphical languages and information models that capture

Polybutadiene Click Chemistry: A Rapid and Direct Method for Vat Photopolymerization

October 10, 2023
Author(s)
Levi Moore, Van Michael Saludo, Oliver Grasdal, Kayleen Smith, Thomas Kolibaba, Jason Killgore, Jacob Marcischak, Jeremy Snyder, Gregory Yandek, Kamran Ghiassi
Thiol-ene click chemistry was utilized to crosslink unmodified commercial liquid polybutadiene, and complex geometries were printed using vat photopolymerization. Polybutadiene contains reactive moieties as a result of its production process, and were used

A Total Break of the 3WISE Digital Signature Scheme

October 9, 2023
Author(s)
Daniel Smith-Tone
A new batch of ''complete and proper'' digital signature schemes submissions has recently been published NIST as part of its process for establishing post-quantum cryptographic standards. This note communicates an attack on the 3WISE digital signature

Fundamental Equation of State for Fluid Tetrahydrofuran

October 9, 2023
Author(s)
Felix Fiedler, Joel Karog, Eric W. Lemmon, Monika Thol
An empirical equation of state in terms of the Helmholtz energy for tetrahydro- furan is presented. In the validity range from the triple-point temperature up to 550 K and pressures up to 600 MPa, the equation of state enables the calculation of all

Grain size in low loss superconducting Ta thin films on c-axis sapphire

October 9, 2023
Author(s)
Corey Rae McRae
In recent years, the implementation of thin-film Ta has led to improved coherence times in superconducting circuits. Efforts to further optimize this materials stack have become a focus of the materials for superconducting quantum computing subfield. It

NIST's Antenna Gain and Polarization Calibration Service Reinstatement

October 9, 2023
Author(s)
Josh Gordon, Benjamin Moser
After a five-year renovation of the National Institute of Standards and Technology (NIST) Boulder, CO, antenna measurement facility, the Antenna On-Axis Gain and Polarization Measurements Service SKU63100S was reinstated with the Bureau International des

Capture and Analysis of Traffic Traces on a Wide-Area NDN Testbed

October 8, 2023
Author(s)
Sankalpa Timilsina, Davide Pesavento, Junxiao Shi, Susmit Shannigrahi, Lotfi Benmohamed
High-quality network traffic measurements from realistic network deployments are crucial to analyze and better understand emerging network technologies for the purpose of maturing them. However, achieving this measurement goal for the Named Data Networking

Using Disaster Surveys to Model Business Interruption

October 8, 2023
Author(s)
Maria Watson, Yu Xiao, Jennifer Helgeson
Business interruption after disasters is an important metric for community resilience planning because has both economic and social consequences. Each additional day that a business is nonoperational further compounds lost revenue, wages, and lack of

Activation loop plasticity and active site coupling in the MAP kinase, ERK2

October 6, 2023
Author(s)
Laurel Pegram, Demian Riccardi, NATALIE AHN
Previous studies of the protein kinase, ERK2, using NMR and hydrogen-exchange measurements have shown changes in dynamics accompanying its activation by phosphorylation. However, knowledge about the conformational motions involved is incomplete. Here, we

Part Deflection Measurements of AM-Bench IN718 3D Build Artifacts
