Development & Validation of A Rapid GC-MS Method for Seized Drug Screening

February 15, 2023
Author(s)
Madeline Bloom, Edward Sisco, Ira Lurie
Controlled substances are one of the most frequently analyzed types of evidence in forensic laboratories. An increase in frequency of seizures in recent years has necessitated a need for rapid screening techniques to decrease case backlogs and expedite

Thermal and Electronic Properties of Ba2MnSe3

February 15, 2023
Author(s)
Adam Biacchi, Oluwagbemiga Ojo, Wilarachchige Gunatilleke, George Nolas
The structural, thermal, and electronic properties of Ba2MnSe3 were investigated. Analysis of the low-temperature heat capacity revealed a low Debye temperature and a low average speed of sound that, together with the bonding in this material, result in a

Topological charge pumping with subwavelength Raman lattices

February 15, 2023
Author(s)
Ian Spielman, Gediminas Juzeliunas, Domantas Burba, mantas Raciunas
Recent experiments demonstrated deeply subwavelength lattices using atoms with $N$ internal states Raman-coupled with lasers of wavelength $\lambda$. The resulting unit cell was $\lambda/2N$ in extent, an $N$-fold reduction compared to the usual $\lambda/2

PSCR Impact Assessment: 2016-2022 Executive Summary

February 14, 2023
Author(s)
Monika Bochert, Marc Leh, Danni Leicht
The purpose of this executive summary is to provide key stakeholders with relevant information about how PSCR spent Public Safety Trust Funds and the impacts of that funding. Furthermore, this report seeks to demonstrate the value and positive outcomes of

Characterization of Reference Materials 8690 to 8693

February 13, 2023
Author(s)
Jessica Reiner, Benjamin Place, N. Alan Heckert, Katherine Peter, Alix Rodowa
The National Institute of Standards and Technology (NIST) Reference Materials (RMs) 8690 Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film-Forming Foams (AFFF) Formulation I, RM 8691 Per- and Polyfluoroalkyl Substances (PFAS) in Aqueous Film

Checking the Net Contents of Packaged Goods

February 13, 2023
Author(s)
Tina G. Butcher, David Sefcik, Lisa Warfield, Elizabeth Benham, Shelby Bowers, Katrice Lippa
This handbook has been prepared as a procedural guide for the compliance testing of net content statements on packaged goods. Compliance testing of packaged goods is the determination of the conformance results of packaging, distribution, and sale of

Discovery of digital forensic dataset characteristics with CASE-Corpora

February 13, 2023
Author(s)
Alexander Nelson, Eoghan Casey
The digital forensics community has generated training and reference data over the course of decades. However, significant challenges persist today in the usage pipeline for that data, from research problem formulation, through discovery of applicable

Uniform Laws and Regulations in the Areas of Legal Metrology and Fuel Quality

February 13, 2023
Author(s)
Tina G. Butcher, David Sefcik, Lisa Warfield, Shelby Bowers, Katrice Lippa
NIST Handbook 130 includes a compilation of model laws and regulations and related interpretations and guidelines designed to encourage uniformity in adoption and implementation of weights and measures laws and regulations. The model laws and regulations

An Automated System for Flow Characterization at Exhaust Ducts and Smokestacks

February 10, 2023
Author(s)
Rodney Bryant, Artur A. Chernovsky, Joseph A. Falco, Iosif Isaakovich Shinder
This report summarizes the design and description for an automated system of velocity traverse probes. Performance of key components of the system are also described. The system is designed for conducting detailed characterizations of flow distributions in

Rydberg Engineering: Recent Techniques for Sensitive Field Measurements

February 9, 2023
Author(s)
Drew Rotunno, Nik Prajapati, Samuel Berweger, Aly Artusio-Glimpse, MATTHEW SIMONS, chris holloway, Amy Robinson
Highly-excited Rydberg atoms have been used for International System of Unit (SI)-traceable radio-frequency (RF) electric field and power measurements, but are limited in sensitivity to order 100 $\mu$V/m/$\sqrtHz}$ by noise and linewidth issues. These
