Measurement, Metrics, and Assurance

Ongoing
The Structured Software Assurance (SSA) task is investigating a methodology known as "structured assurance case models," which have been used extensively in assuring safety-critical systems and applications, for their potential application in assuring other software system qualities, such as

Measurement and Prediction of Local Structure

Ongoing
Functional materials enable applications in the computer, data storage, wireless communication, and energy sectors. The properties of many of these systems are critically dependent on deviations of local atomic arrangements from the global average of the crystal. No single measurement technique can

Measurement Quality in Hydrogen Storage R&D

Ongoing
The hydrogen storage project targets metrologies that assess kinetics and energetics of hydrogen charging and discharging in combinatorial structures as well as the degradation mechanisms that limit life of use. New capabilities are being developed and several existing measurement capabilities are

Measurement and Sampling Standards

Ongoing
A foundational activity that crosscuts our research goals is the development of a variety of standards and test materials to support the effective operation of trace explosive and narcotic detection devices. Trace sampling issues are addressed through fundamental studies on the adhesion and

Measurement Science for Additive Manufacturing Program - 2013

Measurement Science for Additive Manufacturing Program

Ongoing
Objective To develop and deploy measurement science that will enable rapid design-to-product transformation through advances in: material characterization; in-process sensing, monitoring, and model-based optimal control; performance qualification of materials, machines, processes and parts; and end

Measurement Science to Assure the Performance of Green Concretes Project

Completed
Objective: To develop and deliver the measurement science identified by industry for assuring the performance of Industrial-by-Product (IBP) low-carbon footprint concretes with up to 50% by mass of the cement replaced by IBPs by 2015. What is the new technical idea? The industry average cement

Measurement Science to Assure the Performance of Innovative Concretes

Completed
Objective - To develop the measurement science needed to enable greater industry use of innovative concretes, such as 3D printing, more durable and limestone replacement concretes. What is the new technical idea? Manufacturing of cement and production/placement of concrete requires significant

Measurement Science for Building Systems

Ongoing
Objective: To develop and deploy advances in measurement science to enable the design and operation of high-performance building systems while maintaining healthier indoor environments. What is the problem? Buildings account for 40 % of the primary energy consumption, 74 % of the electricity

Measurement Science for Complex Information Systems

Ongoing
What are complex systems? Large collections of interconnected components whose interactions lead to macroscopic behaviors in: Biological systems (e.g., slime molds, ant colonies, embryos) Physical systems (e.g., earthquakes, avalanches, forest fires) Social systems (e.g., transportation networks

Measurement Science for Robotics and Autonomous Systems

Ongoing
Objective To develop and deploy measurement science that advances manufacturing robotic system performance, collaboration, agility, autonomy, safety, and ease of implementation to enhance U.S. innovation and industrial competitiveness. Technical Idea The fundamental idea is to provide the

Measurement Science Tools for Accelerated Weathering of Polymers Project

Ongoing
Objective - Develop a U.S. resource for service life prediction by delivering a suite of measurement science tools including publically available data sets, statistical models, validation data, and geographically specific predictions based on validated statistical models. This resource will be the

Measurement Services (SRMs and Calibrations)

Ongoing
The objective of this project is assure that certifications and uncertainty statements associated with NIST Standard Reference Materials are on a solid scientific foundation. SRMs are artifacts or chemical mixtures that are manufactured according to strict specifications, and are then certified by

A measurement-based approach to 5G supply chain security

Ongoing
NIST is working with a multidisciplinary group of stakeholders to define both the cybersecurity standards for 5G and beyond hardware and to secure the supply chain through developing technology that can detect corrupted hardware before it is put in use.  For an overview of NIST cybersecurity and

Measurements for Hydrogen Storage Materials

Completed
The evaluation of candidate storage materials is complicated by a lack of readily available methods for the direct measurement of hydrogen content. MML is working together with researchers from NCNR, and PML to provide measurement tools to fill this gap. Prompt Gamma Activation Analysis (PGAA) is a

Measurements for minimal cells

Ongoing
Minimal cells are cells whose genome has been stripped of all but those genes essential for replication, in a process called "genome minimization." NIST and collaborators demonstrated genome minimization coupled to single cell imaging as a powerful approach to investigate the minimal genetic

Measurements of Point-Defect Chemistry in Complex Oxides

Ongoing
Project Goal: To develop magnetic resonance, x-ray absorption, electron diffraction, and electrical conductivity measurements to better characterize dilute concentrations of point defects in oxide materials and effectively correlate electro-mechanical properties to measured defect chemistry. Oxide

Measurements and Standards for Botanical Dietary Supplements

Ongoing
Many consumers believe that botanical dietary supplements will improve their health and that these "natural" remedies are both effective and free from the side effects that may occur with other medications. There are occasional reports of inaccurate labeling, adulteration, contamination (with

Measurements and Standards for Contaminants in Environmental Samples

Ongoing
In 1971 NIST issued the first natural environmental matrix SRM for contaminants, SRM 1571 Orchard Leaves, with certified concentrations for trace elements. The development of SRM 1571 Orchard Leaves formalized the approach of combining results from "two or more independent and reliable analytical

Measurements and Standards for Contaminants in Biological (Human) Materials

Ongoing
The development of SRMs to support measurements for contaminants in biological fluids and tissues will expand quality assurance capabilities to important species critical to human health. We will provide SRMs that are representative of the analytical challenges that may be encountered by analysts in

Measurements and Standards for Organic Contaminants in Wildlife Matrices

Ongoing
Monitoring contaminant exposure in wildlife is crucial to assess the impact of environmental contaminants on animal health. The development of methods to screen samples for the presence of new compounds (non-targeted research) and to measure the accurate concentration of known, targeted compounds in

Measurements and Standards to Support Nutrition Labeling

Ongoing
Well-characterized certified reference materials are needed by laboratories in the food testing and nutrition communities to facilitate compliance with labeling laws and improve the accuracy of information provided on product labels so that consumers can make good choices. As a result of the
