Metric Conversion Card

August 2, 2024
Author(s)
Elizabeth Benham, Kristen Dill
NIST SP 365, Metric Conversion Card is a laminated wallet size card includes an 8 cm and 80 mm ruler with approximate unit conversion factors between common International System of Units (SI) and U.S. customary measurement units for length, area, mass

Modeling Spiking Neurons without Spikes

August 2, 2024
Author(s)
Jeff Shainline, Bryce Primavera, Ryan O'Loughlin
While spiking neuromorphic hardware holds promise for efficient implementations of artificial intelligence, the impact has been limited due in part to a lack of learning algorithms that achieve performance superior to conventional deep learning. One

Additive Manufacturing of Highly Entangled Polymer Networks

August 1, 2024
Author(s)
Abhishek Dhand, Matthew Davidson, Hannah Zlotnick, Thomas Kolibaba, Jason Killgore, Jason Burdick
Incorporation of polymer chain entanglements within a single network can synergistically improve stiffness and toughness, yet attaining such dense entanglements through vat photopolymerization additive manufacturing (e.g., digital light processing, DLP)

Construction of Highly Porous and Robust Hydrogen-Bonded Organic Framework for High-Capacity Clean Energy Gas Storage

August 1, 2024
Author(s)
Jia-Xin Wang, Xu Zhang, Changhao Jiang, Teng-Fei Zhang, Jiyan Pei, Wei Zhou, Taner N. Yildirim, Banglin Chen, Guodong Qian, Bin Li
Development of highly porous and robust hydrogen bonded organic frameworks (HOFs) for high-pressure methane and hydrogen storage remains a grand challenge due to the fragile nature of hydrogen bonds. Herein, we report a strategy of constructing the double

Quantum state tracking and control of a single molecular ion in a thermal environment

August 1, 2024
Author(s)
Yu Liu, Julian Schmidt, Zhimin Liu, David Leibrandt, Dietrich Leibfried, Chin-wen Chou
Understanding molecular state evolution is central to many disciplines, including molecular dynamics, precision measurement, and molecule-based quantum technology. Details of this evolution are obscured when observing a statistical ensemble of molecules

Orthogonal Determination of Competing Surfactant Adsorption onto Single-Wall Carbon Nanotubes During Aqueous Two-Polymer Phase Extraction via Fluorescence Spectroscopy and Analytical Ultracentrifugation

July 31, 2024
Author(s)
Christopher Sims, Jeffrey Fagan
A combination of analytical ultracentrifugation (AUC) and fluorescence spectroscopy are utilized to orthogonally probe compositions of adsorbed surfactant layers on the surface of (7,5) species single-wall carbon nanotubes (SWCNTs) under conditions known

Characterizing the Broadband RF Permittivity of 3D-Integrated Layers in a Glass Wafer Stack from 100 MHz to 30 GHz

July 30, 2024
Author(s)
Jacob Pawlik, Tomasz Karpisz, Nicholas Derimow, Sarah Evans, Jim Booth, Nate Orloff, Chris Long, Angela Stelson
We present a method for accurately determining the permittivity of dielectric materials in 3D integrated structures at broadband RF frequencies. With applications of microwave and millimeter-wave electronics on the rise, reliable methods for measuring the

Effects of the Human Presence among Robots in the ARIAC 2023 Industria Automation Competition

July 30, 2024
Author(s)
Leandro Buss Becker, Anthony Downs, Craig I. Schlenoff, Justin Albrecht, Zeid Kootbally, Angelo Ferrando, Rafael Cardoso, Michael Fisher
The ''Agile Robotics for Industrial Automation Competition'' (ARIAC) is an international robotic competition carried out in a simulated factory floor. ARIAC's competitors must perform assembly and kitting tasks by means of controlling four AGVs, one floor

NIST Cloud Computing Forensic Reference Architecture

July 30, 2024
Author(s)
Martin Herman, Michaela Iorga, Ahsen Michael Salim, Robert H. Jackson, Mark R. Hurst, Ross A. Leo, Anand Kumar Mishra, Nancy M. Landreville, Yien Wang
This document summarizes the research performed by the NIST Cloud Computing Forensic Science Working Group and presents the NIST Cloud Computing Forensic Reference Architecture (CC FRA or FRA), whose goal is to provide support for a cloud system's forensic

Advances in Yeast Synthetic Biology for Human GPCR Biology and Pharmacology

July 29, 2024
Author(s)
Geoffrey Taghon, Nicholas Kapolka, Daniel Isom
G protein-coupled receptors (GPCRs) are the largest family of transmembrane receptors in humans. Over 800 GPCRs regulate the (patho)biology of every organ, tissue, and cell type. Consequently, GPCRs are the most prominent therapeutic targets in medicine

Similarity Measures of Mass Spectra in Hilbert Spaces

July 29, 2024
Author(s)
Anthony J. Kearsley, Matthew Roberts
Mass spectrometry (MS) is an analytic tool for measuring mass-to-charge ratios of molecules or molecular fragments. It is often used to identify and classify compounds. A mass spectrometer measures the mass of molecules and produces a signal proportional

A Plan for Global Engagement on AI Standards

July 26, 2024
Author(s)
Jesse Dunietz, Elham Tabassi, Mark Latonero, Kamie Roberts
Recognizing the importance of technical standards in shaping development and use of Artificial Intelligence (AI), the President's October 2023 Executive Order on the Safe, Secure, and Trustworthy Development and Use of Artificial Intelligence (EO 14110)
