Johnson Noise Thermometry

Completed
The NIST Gaithersburg JNT project produces data useful for verification of the International Temperature Scale of 1990 (ITS-90) over a temperature range from 500 K to 930 K. This range overlaps those covered by other thermodynamic methods, most notably the upper-most range of Acoustic Thermometry

Key Comparisons and International Interlaboratory Studies Project

Ongoing
Key comparisons serve as the technical basis for the MRA and must therefore accurately reflect the true relationships between measurement systems maintained by NMI's belonging to the CIPM. The results of key comparisons must also be extensible to members of Regional Metrology Organizations (RMO's)

Kinetic Inductance Spectrophotometry

Ongoing
Within this application space, the transition-edge sensor (TES) microcalorimeter is the most mature technology, with demonstrated x-ray energy resolving capabilities of better than a part per thousand. Current TES readout techniques require the use of superconducting quantum interference device

Knowledge Extraction and Application

Completed
Objective - To develop and deploy advances in standards, measurement science, and software tools using actionable, computable, domain knowledge and data in operations and logistics to improve the reliability, quality, and efficiency of advanced manufacturing systems. What is the technical idea? The

Knowledge Facilitation Project

Ongoing
As we grow to rely on the data in our computers, and that data is shared more frequently, the need for security of that data also grows. Our staff depends upon the confidentiality, integrity, and availability of the data we store and process for them. Confidentiality refers to allowing access to our

Label-free imaging of cells and their extracellular matrix by SPR imaging

Ongoing
Cellular remodeling of their neighboring environment, extracellular matrix (ECM), is an important biological process from development biology, to wound healing, to diseases and cancers – this is a challenging process to measure and quantify. Surface plasmon resonance imaging (SPRI) has been

Landscape Review of Forensic Science Training for Officers of the Court

Completed
The 2009 NAS Report highlighted the need for forensic science training for judges and lawyers noting, “Lawyers and judges often have insufficient training and background in scientific methods, and they often fail to fully comprehend the approaches employed by different forensic science disciplines

Laser Power and Energy Meter Calibrations

Ongoing
We serve Industry, DoD, and research institutions by calibrating instruments used to measure the power or energy emitted by a laser, or single photon source. From Single Photons to Kilowatts, Longwave Infrared to Deep Ultraviolet, Free-space and Fiber, we can calibrate your instruments. The chart to

Laser Stabilization and Coherence with Optical Resonators

Ongoing
Coherent laser interrogation of the narrowband electronic ‘clock’ transition is required to realize the very high spectroscopic resolution that make optical clocks so precise. At the same time, phase fluctuations in the laser interrogation can compromise the frequency stability of the optical clock

Laser-wavelength conversion with nonlinear photonics

Ongoing
Many sophisticated technologies, including detection and characterization of biological samples, quantum sensing of magnetic and electric fields, time standards based on atomic clocks, and precision metrology, demand versatile laser sources spanning a broad range of wavelengths. Nonlinear optics

Latent Print AFIS Interoperability Working Group

Ongoing
Why is AFIS Interoperability Important? Automated fingerprint identification systems (AFIS) allow latent print examiners to search fingerprint files and to transmit fingerprint images. However, examiners often lack the technological ability to access AFIS in neighboring jurisdictions. In addition

Lead-Free Solder

Completed
The U.S. microelectronics industry has clearly articulated the measurement needs for lead-free solders, and for solderability and assembly. For example, the urgency for materials data for lead-free solders has been specified in the 1997 IPC, 1999 International Technology Roadmap for Semiconductors

Lead-Free Surface Finishes for Electronic Components: Tin Whisker Growth

Completed
Tin is widely used as a coating in the electronics industry because it provides excellent solderability, ductility, electrical conductivity, and corrosion resistance. Unfortunately, tin whiskers often grow spontaneously from pure tin electrodeposits and short-circuit finely pitched electrical

SI Length and Traceability

Ongoing
Laser interferometry, which measures distances in terms of light wavelength, provides the backbone of top-level length metrology in industry and science. This project develops techniques to facilitate the tie between interferometer-based length measurements and the SI definition of length (in terms

Light-matter interactions in Semiconductor Nanostructures

Ongoing
We investigate the interaction of light with semiconductor-based nanostructures. We extend concepts of entanglement and coherence in atomic physics to our solid-state systems. Our devices are based on semiconductors, like GaAs. We use InAs quantum dots (QDs) in GaAs as artificial atoms; they have

Lightweight Cryptography

Ongoing
For more information regarding the Lightweight Cryptography, please visit the Computer Security Resource Center (CSRC).

Live Cell Imaging of Induced Pluripotent Stem Cell Populations

Ongoing
As part of our program in Cell Biology , our live cell image program supports the advancement of induced pluripotent stem cell (iPSC) technology in three ways: 1) Identification of process control measurements: A critical component to the translation of iPSCs into therapeutic applications is to

Living Yeast Cell Reference Material (RM 8230)

Ongoing
Quantification of total and viable microbial cells is critical for applications ranging from assessment of DNA extraction efficiency in support of microbial metagenomics to characterization of antimicrobial efficacy. In addition, safe biological materials are needed to substitute for true biothreat

LMR and LTE Interfacing

Ongoing
The Wireless Broadband Technology Demonstrator is part of an effort of DHS OIC to evaluate how wireless broadband technology can be integrated with existing LMR and other first responder and law enforcement communications.PSCR provides independent verification, testing, and support on behalf of DHS

LNP-RNA Research Grade Test Material

Ongoing
The currently planned LNP/RNA material (designated RGTM 10240) will include a fragment of the SARS-CoV-2 genome that is approximately 4 kb in length. This fragment was previously included (in unencapsulated form) as “Fragment 1” of NIST RGTM 10169. The RNA fragment is not designed for cell-based

Local Control

Ongoing
In March 2012, the National Public-Safety Telecommunications Council (NPSTC) Local Control Task Group published a report titled, “Local Control in the Nationwide Public Safety Broadband Network”. The NPSTC report identified four areas where users will need some type of control in respect to first

Local and Dynamic Quality Priority and Pre-emption

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA). FirstNet

Long Wavelength Sensors and Applications

Ongoing
Our project designs and micro-fabricates custom devices that achieve sensitivity at fundamental limits and are based on the principles of superconductivity. We often work in large collaborations to apply these devices to challenging measurements of high scientific interest, such as those which
