A Guide to United States Personal Protective Equipment Compliance Requirements

February 1, 2023
Author(s)
Jennifer Marshall, Erik Puskar, Lisa Benson
This Guide addresses compliance requirements for personal protective Equipment (PPE) used in the workplace, except for PPE used in a nuclear or medical setting. Several U.S. federal agencies administer regulations associated with Personal Protective

A method for pole figure measurements via a dynamic segmented spiral scheme

February 1, 2023
Author(s)
Surya Chandramouleeswaran, Adam Creuziger, Kip Findley
A new method for pole figure measurement is described, titled a dynamic segmented spiral scheme. Compared to schemes currently in use, the dynamically segmented spiral scheme was shown to have advantages in term of evenness of pole figure coverage, time

A Non-Intrusive Fluorescent Pattern for Internal Microscale Strain Measurements Using Digital Image Correlation

February 1, 2023
Author(s)
Ami Ahure Powell, William Mulhearn, Shawn Chen, Stephan J. Stranick, Jeffrey Gilman, Mark Iadicola, Jeremiah Woodcock
A non-intrusive and non-disruptive internal fluorescent pattern is designed, developed, and tested using digital image correlation (DIC), an effective non-contact optical method, to measure deformation at internal planes of a polymer matrix material. The

Dynamic structural and microstructural responses of a metal organic framework type material to carbon dioxide under dual gas flow and supercritical conditions

February 1, 2023
Author(s)
Andrew J. Allen, Eric J. Cockayne, Winnie Wong-Ng, Jeffrey Culp, Ivan Kuzmenko
The structural and microstructural responses of a model metal-organic framework (MOF) material, Ni(3-Methy-4,4'-bipyridine)[Ni(CN)4] (Ni-BpyMe or PICNIC 21), to CO2 adsorption and desorption are reported for in situ small-angle X-ray scattering (SAXS) and

Optical-cavity-based primary sound standard

February 1, 2023
Author(s)
Akobuije Chijioke, Richard A. Allen, Steven E. Fick, David Long, Benjamin Reschovsky, Jared Strait, Randall P. Wagner
We propose an optical sound standard in which the sound pressure is directly measured by using an optical cavity to observe the induced change in the refractive index of air. In this method, an optical cavity is coupled with an acoustic cavity, with the

They're phishing for you: be the one that got away

Complete collision data set for electrons scattering on molecular hydrogen and its isotopologues: IV. Vibrationally-resolved ionization of the ground and excited electronic states.

January 31, 2023
Author(s)
Yuri Ralchenko, Barry I. Schneider, Liam Scarlett, Eric Jong, Igor Bray, Starsha Odelia, Mark Zammit, Dmitry Fursa
We present a comprehensive set of vibrationally-resolved cross sections for electron-impact ionization of molecular hydrogen and its isotopologues (H2, D2, T2, HD, HT, and DT) in both the ground and excited electronic states. We apply the adiabatic-nuclei

Separable Shape Tensors for Aerodynamic Design

January 31, 2023
Author(s)
Zachary J. Grey, Andrew Glaws, Olga Doronina
Airfoil shape design is a classical problem in engineering and manufacturing. In this work, we combine principled physics-based considerations for the shape design problem with modern computational techniques using a data-driven approach. Modern and

Design Guide for New Tornado Load Requirements in ASCE 7-22

January 30, 2023
Author(s)
Erik Perfetto, James Taylor, Karah Osburn, Brian O'Connor, Marc Levitan, Jennifer Mitchell
This instructional guidance is for design professionals and building officials to help them determine when a building or other structure is required to be designed to minimum tornado loads and how to calculate design tornado forces. This guide is in

Handout: Users Are Not Stupid: 6 Cybersecurity Pitfalls Overturned

January 30, 2023
Author(s)
Julie Haney, Susanne M. Furman
The cybersecurity community tends to focus and depend on technology to solve today's cybersecurity problems, often without taking into consideration the human element - the key individual and social factors impacting cybersecurity adoption. This handout
