National Software Reference Library

Ongoing
The National Software Reference Library (NSRL) is designed to collect software from various sources and incorporate file profiles computed from this software into a Reference Data Set (RDS) of information. The RDS can be used by law enforcement, government, and industry organizations to review files

National Type Evaluation Program (NTEP)

Ongoing
NTEP requires industry to submit prototype weighing devices for evaluation to determine whether or not it meets the uncertainties which are related to tolerances associated with the intended final use in the marketplace. All devices sold in the United States for "legal for trade" purposes must pass

National Windstorm Impact Reduction Program Coordination

Ongoing
Objective - To support NIST's statutory Lead Agency role of coordinating National Windstorm Impact Reduction Program (NWIRP) research and implementation activities. What is the new technical idea? This project supports coordination, management, and leadership of the National Windstorm Impact

Nature of the Threat

Ongoing
"Improving Particle Collection Efficiency of Sampling Wipes used for Trace Chemical Detection", Gillen, Greg and Lawrence, Jeffrey and Sisco, Edward and Staymates, Matthew E. and Verkouteren, Jennifer and Robinson, Elizabeth L. and Bulk, Alexander, Anal. Methods, 14, 581-587 (2022). http://dx.doi

NCAL: Data Management

Ongoing
In the mechanical testing and materials science communities there is not a widely accepted solution for data management of test data. As part of NIST efforts on data archiving, provenance, and availability, we have worked to improve our data practices. We have extended our system beyond many out-of

NCAL: Diffraction Stress Measurement Under Applied Load

Ongoing
Using X-ray diffraction (XRD) techniques one can measure the full stress tensor just inside the surface of a sheet metal specimen under applied loading. This permits the measurement of biaxial stress states resulting from directly applied deformation (see NCAL: Multiaxial Material Performance) or

NCAL: Intermediate Strain Rate Testing

Ongoing
This project seeks to improve servohydraulic testing methods at intermediate strain rates by addressing the well-known problems associated with excessive stress oscillations (ringing) that currently limit our understanding of the mechanical behavior of engineering materials for loading conditions

NCAL: International Documentary Standards Activities

Ongoing
NIST Center for Automotive Lightweighting (NCAL) staff participate in many different international standards committees (e.g. ISO TC 164, ASTM E28 and D30); however, our main focus has been in the mechanical testing of metals and, to a lesser extent, composites. We work on the calibration and

NCAL: Materials Testing 2.0

Ongoing
The traditional approach to calibrating material models, known as Materials Testing 1.0, is a time-consuming and costly process that requires multiple experiments to be performed on different types of testing equipment. This not only results in high capital costs for testing machines but also leads

NCAL: Multiaxial Material Performance

Ongoing
Modern metal forming methods are designed and optimized using digital models of specific manufacturing operations. These models rely on a precise understanding of the mechanical behavior of sheet materials as they undergo multiaxial loading out to large plastic strains without failure (necking or

NCAL: NIST Center for Automotive Lightweighting

Ongoing
The ongoing development of new, advanced lightweight materials presents opportunities for the USA automotive industry to produce better, more reliable and less expensive products provided the new materials can be efficiently manufactured. The use of lightweight materials in automobiles, such as

NCAL: Quantifying Crystallographic Texture and Phase Fraction

Ongoing
Predicting the deformation and force response of a polycrystalline material with the level of accuracy needed by today’s manufacturers requires knowledge of the aggregate deformation and force response of all the grains in the material. Polycrystalline materials will respond differently depending on

NCAL: Tension-Compression Testing

Ongoing
The inability to predict the mechanical behavior of new automotive alloys during forming has generated strong demand in industry for more advanced material models and test methods necessary to calibrate them. Industry is particularly interested in modeling the behavior of advanced sheet metals

NCNR DAC and CCUS efforts

Ongoing
Objectives To advance US competitiveness in Direct Air Capture (DAC) and Carbon Capture, Usage, and Sequestration (CCUS) Use advanced neutron scattering techniques to understand the adsorption process for the most promising materials for adsorption-based carbon capture and provide avenues to

NEHRP Extramural Research

Completed
Objective - A task order to assist NIST and the NEHRP agencies in updating the NEHRP Strategic Plan will be awarded to a policy contractor. In addition, other planned FY 2020 extramural research will be assigned by task order to the new IDIQ contractor once that award is made. It is anticipated that

Neighborhood Area Communication Network

Completed
The smart grid is comprised of many networks (domains) with various boundaries that have to be interconnected to provide end-to-end services. The challenge is to design network architectures that can meet the interoperability requirements for inter-domain and intra-domain communications, as

Network Modeling for Public Safety Communications

Ongoing
Advances in broadband wireless technologies developed by standard developing organizations (SDOs) such as 3GPP and IEEE 802 offer unprecedented capabilities that have the potential to improve the effectiveness of first responders. Our efforts are aimed at evaluating how well emerging solutions meet

Neuromorphic Computing

Ongoing
Spin Torque Oscillators: The research at the heart of this effort is to better understand and control mutual synchronization of arrays of spintronic nanoscale oscillators operating in the range of 10 GHz to 40 GHz. The devices under study are well suited to neuromorphic applications because they are

Neuromorphic Device Measurements

Ongoing
One type of device that is emerging as an attractive artificial synapse is the resistive switch, or memristor. These devices, which usually consist of a thin layer of oxide between two electrodes, have conductivity that depends on their history of applied voltage, and thus have highly nonlinear

New Chemical Measurement Methods

Ongoing
The Biochemical and Exposure Science Group (BESG) located at the Hollings Marine Laboratory is focused on advancing measurement techniques to effectively detect compounds of emerging concern. The BESG has a long history of developing accurate and precise analytical methods for emerging organic
