Reliable Vaccine Storage

Completed
Our group examines best practices for the storage and monitoring of vaccines in partnership with the Centers for Disease Control and Prevention’s (CDC) Vaccine Supply and Assurance Branch. Vaccines are highly temperature sensitive, and inappropriate storage conditions can render them ineffective...

RMAT Laboratory Programs

Ongoing
Examples of Current Activities: Cell Counting and viability are key measurements critical for decision making from R&D to manufacturing. We recently developed an approach for evaluating the quality of cell counting measurements through experimental design and statistical analysis that does not...

Smart Grid Interoperability Testbed Facility

Ongoing
Objective - To develop and progress an advanced multi-mode interacting measurement testbed that leverage cross-OU expertise to facilitate implementation, validation, and full characterization of smart grid interoperability standards and smart grid performance, with a particular emphasis on DER...

Smart Grid Testing and Certification

Completed
Objective: To accelerate the development of new test programs and improve existing test programs for smart grid interoperability and security by utilizing the ANSI/NEMA Interoperability Process Reference Manual (IPRM) testing and certification framework, and demonstrating benefits of testing and...

Solid-state lighting metrology

Ongoing
Light Emitting Diodes (LEDs) are increasingly being introduced into lighting market, and solid state lighting (SSL) is becoming a reality. But, this new technology still faces many challenges. Lighting consumes a huge amount of energy, currently 22% of all electricity consumed in the U.S. White LED...

Speaker and Language Recognition

Ongoing
Current Speaker and Language Recognition technology activities: Speaker Recognition Evaluation series: (1996-) A biennial NIST evaluation of fully automated text-independent speaker recognition technology. View the 2012 NIST SRE report. Human Assisted Speaker Recognition Evaluation series: (2010- )...

Speech Analytics

Ongoing
Current speech analytics work: OpenSAT is a new speech analytic evaluation series designed to include developers from multiple speech analytic technologies where common datasets are used in NIST evaluations. The goal is to bring together developers focused on different speech analytic tasks to...

Standard Platinum Resistance Thermometer Calibration Laboratory (SPRTCL)

Ongoing
The SPRTCL provides an extensive list of calibration services that cover the whole temperature range for which long-stem SPRTs, including high-temperature SPRTs, are the ITS-90 interpolation artifacts. This range spans from the triple point of argon (-189.3442 °C) to the freezing point of silver...

Standard Reference Materials for Hexavalent Chromium in Contaminated Soil

Completed
During the last century, chromate and dichromate chemical production facilities processed considerable amounts of chromite ore for industrial manufacturing purposes. The waste material from these operations called chromite ore processing residue (COPR) was disposed of in waste sites across the...

Standard Solution SRMs Provide Traceability for Millions of Measurements

Ongoing
Literally millions of measurements of elemental composition are performed each year worldwide. The vast majority of these measurements depend upon reference materials for establishing traceability of results to the SI. Leveraged through commercial CRM producers, the NIST SRM 3100 series provides an...

Standards

Ongoing
Standards for Optical Based Standoff Detection NIST is researching methods for creating explosive threat materials standards relevant to optical detection technologies (e.g. that result in samples with particle morphologies similar to those found in explosive threat devices). This includes both...

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose...

Standards for Metagenomics

Ongoing
Metagenomics is a powerful technology combining high-throughput (a.k.a. “next-generation”) sequencing with advanced bioinformatics to identify and quantify mixtures of organisms in a sample. Metagenomics workflows consist of 4 main steps: Sample collection: location, amount, storage, etc. Extraction...

Standards to Support Biological Detection in the Field

Ongoing
NIST is working in partnership with the Department of Homeland Security Science and Technology Directorate (DHS S&T) to develop methods, guidance, standards, and reference materials to support and improve our Nation's ability to detect and respond to suspected biothreat incidents. Specific...

Standards to Support Biothreat Detection

Ongoing
Since 9/11 and the subsequent anthrax attacks in 2001, suspicious white powder incidents continue to occur within the US, often requiring Federal law enforcement response. Suspect samples are sent to public health laboratories for confirmatory evaluation, which can take hours to weeks to receive...

Study of Microheterogeneity in Solid Reference Materials

Ongoing
Presently there are a variety of analytical techniques that are served by few or no reference materials due to the small sample sizes they require. NIST currently certifies solid reference materials at or above the 100 mg mass level in most cases with no mention of the effect of using smaller sample...

Surrogate protein particle standards

Ongoing
Intended Impact This work will enable industry to obtain accurate, reproducible counts of protein particles, and to differentiate protein particles from other particle types, resulting in greater drug efficacy and safety. Objectives Create a polydisperse suspension of polymer particles that mimic...

Synthetic Biology

Ongoing
New measurement methods and tools are required for biology to emerge fully as an enabling, practical platform for engineering. The Cellular Engineering Group works to provide a foundation of measurement assurance to support the control and rational design of biological function. Through state of the...

Synthetic Fecal Metabolite Calibrant Solution (RGTM 10212)

Ongoing
Metabolomics is an exciting and dynamic field in life sciences that harnesses cutting-edge technologies to identify and characterize small molecules, or metabolites, within cells, tissues, or organisms, collectively known as the metabolome. The wealth of evidence in the literature underscores the...
