ITL Forensic Science Program

Ongoing
The principal goals of the Program are to develop standards, measurement methods, tests, validation studies, and technology to: Better understand and improve the accuracy and reliability of forensic science. Provide scientifically validated bases for forensic methods and standards. Establish...

ITL Quantum Information Program

Ongoing
The principal goals of the ITL Quantum Information Program are: To understand the potential (both opportunities and risks) for quantum information to revolutionize information science. To develop theory, methods, architectures and algorithms to enable engineering and testing of quantum computing...

JARVIS-ALIGNN, JARVIS-ALIGNN-FF

Ongoing
ALIGNN uses a line graph neural networks to include bond distances and angular information graph to incorporate finer details of atomic structure, leading to high accuracy models. While the nodes of an atomistic graph correspond to atoms and its edges correspond to bonds, the nodes of an atomistic...

JARVIS-DFT

Ongoing
JARVIS-DFT hosts materials property data for ~40000 bulk and ~1000 low-dimensional crystalline materials and the database is continuously expanding. Some of the properties in the database are: formation energies, bandgaps, elastic, piezoelectric, dielectric constants, and magnetic moments...

JARVIS-FF

Ongoing
Many classical force-fields are developed for a particular set of properties (such as energies) and they may not have been tested for properties or configurations outside the training (such as elastic constants, defect formation energies or energies for metastable phases). JARVIS-FF provides an...

JARVIS-ML

Ongoing
JARVIS-ML introduced Classical Force-field Inspired Descriptors (CFID) as a universal framework to represent a material’s chemistry-structure-charge related data. With the help of CFID and JARVIS-DFT data, several high-accuracy classifications and regression ML models were developed, with...

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

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 the wavelength of light, 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...

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...

Linguistic and AI Support for Collective Standards Development

Ongoing
Standards are increasingly part of complex digital ecosystems which may span dozens of documents, several different domains of science and engineering, and hundreds of contributors from different countries and backgrounds. It can be challenging to ensure that standards are consistent, meet...
