Augmented Intelligence for Manufacturing Systems (AIMS)

Ongoing
Objective To overcome existing measurement challenges via augmented intelligence, the fusion of integrated metrology, physics-based models, and artificial intelligence, to enable monitoring, diagnostics, and prognostics of manufacturing systems and their processes. Technical Idea One research

Basic Metrology (Archive): New Standardization of Ra-228

Completed
Radium-228 has a half-life of (5.75 years) and decays by emitting a beta particle. It is a radioactive decay product in the thorium-232 decay series, a very difficult and complex decay chain: 232Th→ 228Ra → 228Ac → 228Th → 224Ra → 220Rn → 216Po → 212Pb → 212Bi → 208Tl → 208Pb(stable); with a sub

Basic Metrology: Standard Reference Data on Radiation Interactions

Ongoing
This work continues in the Division's Photon and Charged-Particle Data Center. The compilations of the Data Center rely heavily on evaluating measurements and on their synthesis with available theory to extend the data and provide for comprehensive coverage over broad ranges of energy and materials

Biomanufacturing Initiative

Ongoing
The objective of the NIST biomanufacturing program is to support US biopharmaceutical industry delivery of high quality and low cost protein drugs around the world. The mission is fulfilled through the development of standards, measurement science, and state of the art tools that support advances in

Carbon Capture, Use, and Storage

Ongoing
Carbon Capture, Use, and Storage (CCUS) requires a suite of technologies to capture carbon dioxide from industrial point sources, the atmosphere, and the ocean; convert carbon dioxide into products such as fuels, chemical feedstocks, and building materials; and sequester carbon dioxide deep

Computational Chemistry

Ongoing
Given the combinatorial possibilities for combining fundamental elements to create novel molecules, bench science experimentation is impractical as a wholesale means to discovery. By contrast, computational resources abound and thereby offer a possible alternative. However, this immense resource is

Crystallographic Databases

Ongoing
Impact and Customers Materials with new or improved properties are continually being developed to meet demands for increased functionality of components and devices at decreased costs. Examples of multi-million dollar industries driven by materials advances are solid-state lighting (GaN-based

Diffraction Metrology and Standards

Ongoing
Diffraction techniques can provide data on a number of sample characteristics. Therefore, the method of certification and the artifact itself are chosen to address a specific measurement issue pertinent to a diffraction experiment. NIST diffraction SRMs may be divided into five groups: Line Position

Digital PCR

Ongoing
With appropriately validated assays, digital polymerase chain reaction (dPCR) determines the number of DNA targets (copies) per reaction partition, without the need for a standard curve. Reaction partitions can be in the form of fixed chambers in a microfluidic device, referred to as chamber digital

External RNA Controls Consortium

Completed
While early gene expression measurements with DNA microarrays were groundbreaking in their ability to reveal biological activity, the results were irreconcilable and irreproducible. Industry leaders approached the National Institute of Standards and Technology (NIST) in 2003 for help with addressing

Gas properties for flow metering

Ongoing
NIST has two on-line databases that include accurate gas viscosity values: SEMIPROP - NIST Standard Reference Database 134 - for selected semiconductor process gases NIST Chemistry WebBook - for heat transfer fluids, components of air, components of natural gas [Note: as of February 2014, the NIST

Genome in a Bottle

Ongoing
Consortium goals: The Genome in a Bottle Consortium is a public-private-academic consortium hosted by NIST to develop the technical infrastructure (reference standards, reference methods, and reference data) to enable translation of whole human genome sequencing to clinical practice and innovations

Inorganic Phase Equilibrium Data

Ongoing
Every deliberate effort to develop a new material or to improve processing begins with chemical composition and the conditions (temperature, pressure) under which pure compounds and their mixtures are stable ( an equilibrium phase diagram ). In the absence of such information, materials scientists

Material Qualification

Ongoing
Objective To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological

Metrology for Multi-Physics AM Model Validation

Completed
Objective To provide reference data for the validation of multi-physics models of metal additive manufacturing processes to enable improvement of AM process models and more rapid and predictable process development for AM production by manufacturers. What is the Technical Idea? The Metrology for

The NIST Chemistry Webbook

Ongoing
Intended Impact It is part of NIST's mission to distribute Standard Reference Data to scientists, engineers, educators, and the general public. The NIST Chemistry WebBook is intended to help fulfill NIST's mission by distributing such data over the Internet. Objective Develop a web site
