Textiles in a circular economy: An assessment of the current landscape, challenges, and opportunities in the United States

November 30, 2022

Author(s)

Kelsea Schumacher, Amanda L. Forster

The production and consumption of textile products traditionally follows a largely linear (take, make, use, discard) economic model. Textiles are currently being produced in greater volumes than ever before, even after accounting for population growth, and

Cannabis Laboratory Quality Assurance Program: Exercise 2 Moisture Final Report

In 2020, NIST launched Cannabis Laboratory Quality Assurance Program (CannaQAP) to improve the comparability of the analytical measurements of cannabis and cannabis-derived products in forensic and cannabis (hemp and marijuana) testing laboratories

On the Feasibility of COVID-19 Proximity Detection Using Bluetooth Low Energy Signals

November 29, 2022

Author(s)

Nader Moayeri, Chang Li, Lu Shi

The COrona VIrus Disease – 2019 (COVID-19) pandemic has had a profound effect on the entire world. With the onset of the pandemic in 2020, also started various efforts around the world to automate the contact tracing process to increase its efficacy. Most

The thermally-coupled imager: A scalable readout architecture for superconducting nanowire single photon

November 29, 2022

Author(s)

Adam McCaughan, Yao Zhai, Boris Korzh, Jason Allmaras, Bakhrom Oripov, Matthew Shaw, Sae Woo Nam

Although superconducting nanowire single-photon detectors (SNSPDs) are a promising technology for quantum optics, metrology, and astronomy, they currently lack a readout architecture that is scalable to the megapixel regime and beyond. In this work, we

Twenty-First Annual Report on Federal Agency Use of Voluntary Consensus Standards and Conformity Assessment Activities
