Effect of Aging on Unidirectional Composite Laminate Polyethylene for Body Armor

March 8, 2023
Author(s)
Amy Engelbrecht-Wiggans, Ajay Krishnamurthy, Amanda L. Forster
Ballistic-resistant body armor has increasingly been using flexible unidirectional (UD) composite laminates that comprise multiple layers in the armor construction. Each UD layer contains high-performance fibers held in place using very low modulus binder

MOFX-DB: An online database of computational adsorption data for nanoporous materials

January 4, 2023
Author(s)
N. S. Bobbitt, Kaihang Shi, Benjamin J. Bucior, Haoyuan Chen, Nathaniel Tracy-Amoroso, Zhao Li, Yangzesheng Sun, Julia Merlin, Joern Ilja Siepmann, Daniel Siderius, Randall Q. Snurr
Machine learning and data mining coupled with molecular modeling have become powerful tools for materials discovery. Metal-organic frameworks (MOFs) are a rich area for this due to their modular construction and numerous applications. Here, we make data

Breaking Category Five SPHINCS+ with SHA-256

September 28, 2022
Author(s)
Ray Perlner, David Cooper, John M. Kelsey
SPHINCS+ is a stateless hash-based signature scheme and a finalist in the NIST PQC standardization process. Its security proof relies on the distinct-function multi-target second-preimage resistance (DM-SPR) of the underlying keyed hash function. The

Mass Spectral Library Methods for Analysis of Site-Specific N-Glycosylation: Application to Human Milk Proteins

September 16, 2022
Author(s)
Concepcion Remoroza, Meghan Burke Harris, Xiaoyu (Sara) Yang, Sergey Sheetlin, Yuri Mirokhin, Sanford Markey, Dmitrii V. Tchekhovskoi, Stephen E. Stein
We present a mass-spectral library-based method for analyzing site-specific N-linked protein glycosylation. Its operation and utility are illustrated by applying it to both newly measured and available proteomics data of human milk glycoproteins. It

Measurement Challenges for Scaling Superconductor-based Quantum Computers

June 23, 2022

Pete Hopkins, Manuel Castellanos Beltran, John Biesecker, Paul Dresselhaus, Anna Fox, Logan Howe, David Olaya, Adam Sirois, Dylan Williams, Samuel P. Benz, Alirio De Jesus Soares Boaventura, Justus Brevik
… testing, 2) measurement tools, and 3) calibration standards that will be required for accurate modeling and …

Computations of Particle Surface Characteristics Using Optical and X-Ray CT Images

October 12, 2021
Author(s)
E Masad, S Saadeh, T Al-Rousan, Edward Garboczi, D Little
The description of particle surface characteristics is of interest in many disciplines in science and engineering such as powder technology, geology, soil science, and infrastructure materials. Consequently, there is a need to develop methods to quantify

Rapid Identification of Synthetic Routes to Functional Metastable Phases Using X-Ray Probed Laser Anneal Mapping (XPLAM) Time-Temperature Quench Maps

June 6, 2021
Author(s)
Robert T. Bell, Peter A. Beaucage, Marc J. Murphy, Aine Connolly, David Ginley, Ulrich Wiesner, R. B. Van Dover, Michael O. Thompson
Most material systems have known or predicted functional phases that are metastable at standard temperature and pressure. While substantial advances have been made in the high-throughput and combinatorial synthesis of materials with a range of

Recent research and development in photometry at NIST

April 22, 2021
Author(s)
Yuqin Zong, Maria Nadal, Benjamin K. Tsai, C Cameron Miller
Many developments were made in recent years in photometry at NIST for reducing measurement uncertainties, increasing calibration efficiencies, and adding measurement capabilities. The 40 years old photometry laboratory has been renovated. The new
