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
