Seabird Tissue Archival and Monitoring Project (STAMP)

Ongoing
Seabirds are an important group of upper trophic-level marine organisms with potential for accumulating lipophilic chemical contaminants which have been linked to adverse health effects. Analyses of seabird tissues, particularly eggs, have played important roles in temporal and spatial ecosystem...

Searching the ICSD for new functional materials from first principles

Ongoing
The combination of increased computing power and the improvement and streamlining of numerical techniques over the past decade have allowed for high quality first principles density functional theory calculations to be routinely performed on large numbers of compounds. This computational power, when...

Secondary Ion Mass Spectrometry Ion Source Development

Ongoing
In SIMS, a typical analysis requires <1 % of the surface to be sampled, which minimizes chemical damage in the form of molecular fragmentation due to energetic ion bombardment. Cluster sources such as C 60 and Ar GCIB allow for efficient removal of the damage volume, and by operating the analysis...

Security: Air-Kerma Measurements in High Energy X-ray Beams

Completed
X rays are used for imaging the contents of vehicles and cargo. Because of the need to penetrate through the thickness of the wall of containers and vehicles in addition to the objects contained within, these systems rely on the use of penetrating radiation such as high energy megavoltage x rays...

Security (Archive): Neutron Detector Replacement Program

Completed
This course of action has included an intense sequence of tests of alternative technologies performed at the Los Alamos National Laboratory and the Nevada National Security Site. NIST has been integral to all phases of these testing programs, including evaluation of submitted detectors, design and...

Security (archive): X-ray Systems for Cargo and Vehicle Inspection Systems

Completed
The American National Standards Institute (ANSI) standard for the image quality indicators of non-intrusive cargo and vehicle inspection systems, ANSI N42.46, was previously developed through a series of meetings hosted by NIST. NIST has conducted and analyzed the results of tests using this...

Security - Health Information Technology

Ongoing
Specifically in the area of health IT, NIST researchers are: Leveraging security automation principles and specifications to develop baseline security configuration checklists and toolkits to aid organizations in implementing the HIPAA Security Rule standards and implementation specifications...

Security for Internet Systems and IETF

Ongoing
Our work will significantly improve the state of security metrology, improving the quantification of operational and technical security and increasing the ability to perform science for information security based on sound, consistent measures. This will initially impact all Federal agencies, and...

Security: Nuclear Forensics Reference Material (RM) Program

Ongoing
NIST coordinates the production and characterization of nuclear forensics reference materials (NFRMs), which are vital for making precise and accurate measurements of nuclear materials. These materials will help ensure that measurements of nuclear material evidence are highly reliable, are traceable...

SED Consulting Program

Ongoing
Description: Specific SED contributions include: Leadership in the establishment of a high standard of statistical practice within NIST via interactions with technical staff, publications, workshops, and seminars. Design and analysis of experiments, and evaluation of measurement uncertainties for...

Seismic Response of Reinforced Concrete Walls

Ongoing
Objective: The project includes two critical tasks identified in Performance Based Seismic Engineering (PBSE): (1) use of simplified reinforced concrete wall models in high-fidelity nonlinear dynamic analysis that have no robust experimental data validation - to be solved by thorough experimental...

AI self-quality assurance using learning curves in feedback loops

Ongoing
One application of artificial intelligence (AI) in materials is the acceleration of materials innovation, which is the mission of the Materials Genome Initiative. However, to decrease the cost and time-to-market, we must continuously assess the quality of models with new facts. AI quality assurance...

Semi-Automatic Curation

Ongoing
Scientific literature is undeniably an important source of scientific data for research but the review and curation of data from literature is both tedious and time consuming. Investigators must sort through many articles to review and extract relevant information. For many areas of research...

Semiconductor Integration of Electronics and Photonics

Ongoing
Using integrated photonics, we generate spectrally flat, dark soliton microresonator frequency combs with accurate alignment to the ITU-T grid. These laser sources support innovation in advanced communication and computation applications. Moreover, technical development in these application areas...

Semiconductor Nanowire Metrology: Electronics, Photonics, and Sensors

Completed
One of the key issues hampering progress in semiconductor nanotechnology is the absence of standardized nanostructures. We address this need through the controlled fabrication and assembly of semiconductor nanowire test structures with well-defined properties. To achieve this, we have manufactured...

Sensing and Imaging of concealed objects

Ongoing
Threats to personal and collective safety abound in our society. The Security Technologies Group (STG) performs research to advance the technology and measurement science of security imaging and sensing. This work includes the establishment of test and evaluation tools, reference test beds, test...

Sensing, Transport, and Simulation

Ongoing
We have recently developed a finite-size scaling approach and special simulation cell aspect ratio—the golden aspect ratio—to enable accurate incorporation of access resistant and bulk diffusion in ionic transport, see the figure. This enables quantitative, and efficient, prediction of ion transport...

Sequential Bayesian Experiment Design

Completed
We develop and publish the optbayesexpt python package. The package implements sequential Bayesian experiment design to control laboratory experiments for efficient measurements. The package is designed for measurements with: an experiment (possibly computational) that yields measurements and...

Serology and Neutralization Assays for COVID-19

Ongoing
Multiplexed bead-based SARS-CoV-2 serological assay We have developed a validated multiplexed bead-based SARS-CoV-2 serological assay that measures different antibodies produced by a patient (IgG, IgM, IgA). In collaboration with the NIST Applied and Computational Mathematics Division, we have...
