RM 8376 Microbial Pathogen DNA Standards for Detection and Identification

Ongoing
RM 8376 consists of 20 individual gDNA components from 19 bacterial strains and 1 human reference genome. Its purpose is to enable developers and regulators to evaluate the analytical performance of metagenomic next generation sequencing (mNGS) tools. The material is certified for chromosomal copy

AC-DC Difference

Ongoing
The use of thermal converters for ac voltage metrology was introduced by Frank Hermach at NIST in 1952. The basic thermal converter is a thermoelement, consisting of a thermocouple positioned at the midpoint of a heater wire, enclosed in an evacuated bulb. The thermoelement senses the heat generated

Activated Carbon and FGD Gypsum Standard Reference Materials

Completed
The role of mercury in the environment is now receiving close scrutiny because ultimately it can bioaccumulate as alkyl mercury in seafood with subsequent risk to human health through trophic transfer. Many industrial sources of mercury have been effectively reduced in recent years, but atmospheric

Additive Manufacturing Part Qualification

Completed
Objective To develop and deploy test methods and protocols, standard test artifacts, exemplar data, data processing tools, and automation tools that create robust post-process measurements and non-destructive testing to enable qualification of AM parts by manufacturers. What is the Problem? To

ANSI/NIST-ITL Standard

Ongoing
February 3, 2023: NIST would like to welcome your participation in the upcoming ANSI/NIST-ITL Standard Update Workshop. This event is open to all biometric subject matter experts (SMEs), biometric system developers and integrators from government, academia, and industry alike, who wish to

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

Automated Vehicles and AV Communications

Ongoing
Automated vehicles (AVs), or Automated Driving Systems-equipped (ADS-equipped) vehicles, have great potential to improve our lives by freeing us from the stress of driving and reducing accidents caused by distractions or poor judgement. Connected, reliable, and safe AVs will spark significant

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: Remote Sensing Methods for Imaging Dose to Water

Ongoing
Ultrasound and laser interferometry, widely used for nondestructive testing and remote sensing applications, are being used here to measure dose distributions in irradiated water phantoms by taking advantage of temperature dependence in the speed of sound and optical index of refraction of water

Biofabrication of Tissue Engineered Constructs

Ongoing
OCT imaging was assessed using a model scaffold-cell system consisting of a polysaccharide-based hydrogel seeded with human Jurkat cells. Four test systems were used: hydrogel seeded with live cells, hydrogel seeded with heat-shocked or fixed dead cells and hydrogel without any cells. Time series

Bioprocessing Laboratory

Ongoing
Current Capabilities Computer controlled liquid nitrogen biostorage system Two culture areas including 4 monitored CO2 incubators 2 Six-foot BSLII biosafety cabinets Measurements- cell count and concentration, STR typing, flow cytometry, cell volume size distribution, conventional transmission and

Calibration Services: Low-Energy Photon Brachytherapy Sources

Ongoing
Since 1999, over 1,500 seeds of more than 40 different designs from 18 manufacturers have been calibrated using the WAFAC. On-site characterization at seed manufacturing plants for quality control, as well as at therapy clinics for treatment planning, relies on well-ionization chamber measurements

Cancer Biomarker Measurements and Collaborations

Ongoing
Collaborations and Cooperative Research Agreements We welcome collaborations and can help with assay validation and development of reference materials. Below are some examples of our collaborations and ways we can develop test materials. Early Detection Research Network (EDRN): Interagency agreement

Carbon Dioxide Measurements and Reference Materials

Ongoing
CO 2 Reference Materials The Gas Sensing Metrology Group at NIST has a long history of providing reference materials to industry, monitoring communities, and academia. The program began in the 1970’s by developing an initial suite of CO2 primary standard mixtures (PSMs) to support the US Department

Carbon Nanotube Reference Materials

Completed
Carbon nanomaterials are expected to play an important role in future technological developments of transistors, photovoltaics, transparent thin film conductors, sensors, and fuel cell electrodes among many potential applications. However, the potential of these materials has been hindered by a lack

Carbon Removal, Capture, Use, and Sequestration

Ongoing
NIST develops benchmark materials, measurements, data, and models to accelerate innovation in and validate performance of materials and technologies for the capture of carbon from air and sequestration in building materials.
