Advanced Security Architectures for Next Generation Wireless

Ongoing
The US Government, and the Department of Commerce in particular, has identified the development and commercialization of Open Radio Access Network (O-RAN) technologies as a strategic priority in the evolution of next-generation wireless networks and a key enabler for the US IT industry to increase

Advanced Spectral Analysis: Two-Dimensional Correlation Spectroscopy (2DCOS)

Ongoing
When a series of spectra are acquired from a sample as a function of temperature, pressure, electric field strength, concentration, or any experimental parameters, conventional spectral analysis is performed by monitoring the intensity change at a specific frequency. However, such a single frequency

Advanced Waveform Co-Channel Interference

Ongoing
The Federal Communications Commission (FCC) spectrum auctions in 2015, resulted in significant rule changes to former federal spectrum bands, causing incumbent federal users to abandon, or share frequency allocations with commercial users. With these changes in licensed spectrum use and associated

Advancing PEEM-based Metrology

Ongoing
With the rise of emergent material systems, nanoscale devices and components, there is a need to assess their electronic properties at similar length scales. Bulk-sensitive measurements provide characteristic information averaged over the sample or device, and these properties may not be uniform

Advancing Power Electronics with Defect Metrology

Ongoing
Power electronics play a central role in all aspects of electrical energy storage, distribution, conversion, and consumption. Currently, power electronics heavily rely on Si-based insulated-gate bipolar transistors (IGBT), which have large footprints, are inefficient, and require extensive cooling

Aerodynamic Flow Visualization

Agility Performance of Robotic Systems

Ongoing
Objective Deliver robot agility performance metrics, test methods, information models, datasets, combined virtual/real testbeds, and planning approaches that will enable manufacturers to more easily and rapidly reconfigure, retask, and redeploy robotic systems. Technical Idea The project is

Agri-Food Manufacturing System and Supply Chain Integration

Ongoing
Objective: Deploy new standards and reference data supporting agri-food manufacturing systems to enable industry to more efficiently and cost effectively produce food-based products of higher quality and with improved food safety. Technical Idea: Today, food producers face many challenges include

AI-based measurements For Imaging

Ongoing
The problem addressed in this work lies in enabling scientists to apply artificial intelligence (AI) based models to deriving measurements from terabyte-sized images. This problem is important as image-based measurements can become more accurate by introducing supervised AI-based models instead of

Air Distribution Impacts in Net-Zero Energy Homes

Ongoing
Objective - Develop the measurement science necessary to evaluate various technological approaches, with a focus on the air distribution systems, to achieve thermally comfortable and healthy net-zero energy residential buildings via innovative monitoring techniques, methods of test, performance

Air Speed Metrology

Ongoing
NIST's wind tunnel has two interchangeable test sections. (See Fig. 1) The upper test section has a uniform cross section; the lower test section has a contracted zone in its center to achieve higher velocities. Upper test section: 2.1 m high × 1.5 m wide × 12 m long; speeds to: 45 m/s (100 mi/hour)

Ambient and Atmospheric Pressure Mass Spectrometry

Ongoing
Surface and Trace Chemical Analysis Group employs a range of commercial pneumatically-assisted electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photoionization (APPI) sources for traditional mass spectrometric chemical analysis, identification

Amplifiers

Ongoing
We have developed parametric amplifiers based on two different technologies: Josephson Junctions and superconductors with high kinetic inductance, a representation of the kinetic energy of superconducting Cooper-pair charge carriers. Junction-based parametric amplifiers (JPAs) are well suited for

Analysis of Copper Incorporation Into Zinc Oxide Nanowires

The lasing capabilities and piezoelectric properties of single ZnO nanowires offer promise for future technologies. However, the photoluminescence of ZnO nanowires differs depending upon the synthesis method and the defects present in the sample. This project was undertaken to characterize zinc

Analysis and Modeling of Atmospheric Particles to Assess Effects on Climate

Ongoing
Spectral data from satellite and ground-based remote sensing instruments are used to monitor the effects of atmospheric aerosols on climate. Determinations of how aerosols interact with sunlight or infrared radiation from Earth’s surface rely upon an aerosol model that approximates the sizes, shapes

ANSI/NIST-ITL Standard

Ongoing
Recent Announcements Save the Date: NIST welcomes your participation in the ANSI/NIST-ITL in-person workshop on April 22-24, 2025 to update the ANSI/NIST-ITL standard. The workshop will be held at the NIST NCCoE facility in Rockville, Maryland. In-person participation is strongly encouraged and

Antenna Metrology Project

Ongoing
NIST CTL’s Antenna Metrology Project combines theoretical models, analytical tools, and custom-developed facilities to advance the field of antenna measurement and share those advances with industry, government, and academic users. Two generations ago, NIST pioneered the near-field scanning

Aperture area measurements

Ongoing
Aperture area measurements are performed at NIST’s aperture area measurement facility, which combines a precise interferometric motion stage with high-resolution optical microscopy. This non-contact method is especially well suited for the measurement of defining apertures with knife edges that are

Applications of Quantum Information

Ongoing
Human-scale physical phenomenon represent the emergent, complex behavior of simple, microscopic laws. In the past twenty years, improved understanding of these microscopic laws have suggested that typical large-scale systems — those used in modern day technology from transistors to mechanical

Applied: Methods in Neutron Detection and Spectroscopy

Completed
Energetic neutrons (> 1 MeV) play a variety of important roles from dosimetry to the fundamental sciences. Fast neutrons can be an often under-appreciated but significant biological dose from accelerators and nuclear facilities, serve as a way of detecting nuclear materials, and can often yield

Applied: Photon Assisted Neutron Detector (PhAND)

Ongoing
Due to the simplicity of the PhAND physics package, any number of detector configurations can be deployed. Basic detector operation is illustrated in Fig. 1. Incident neutrons are absorbed in a 10B film and the charged daughter products (𝜶 7Li) enter the surrounding xenon where they produce xenon
