Advanced Microscopy for Trace and Bulk Particle Characterization

Ongoing
The goal of this project is to help develop innovative metrologies and measurement protocols for micro/nano-scale analysis of particles. In this project, state-of-the-art optical and electron-based microscopy are used to conduct research for quantitative and qualitative analysis of chemical

Advanced Microwave Photonics

Ongoing
NIST is home to a broad interdisciplinary program in quantum information science. NIST is exploring multiple implementations of qubits and strategies for taking advantage of quantum effects to compute, simulate, and improve fundamental measurement strategies. Josephson junctions are at the heart of

Advanced Microwave Radiometer Metrology

Ongoing
Using the NIST radiometer as a test bed, we studied the stability of temperature measurements for infrequent calibrations and developed stability metrics. We developed models to simulate output temperatures from the NIST radiometer, thus enabling the study of radiometer output without having to

Advanced Security Architectures for Next Generation Wireless

Ongoing
National Priorities: The National Strategy to Secure 5G and Implementation Plan goals to: facilitate the rollout of 5G domestically; assess the cybersecurity risks to and identify core security principles of 5G capabilities and infrastructure; address risks to United States economic and national

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-Assistance for Resilience Research and Practice

Ongoing
Objective - In FY25, the project will focus on developing and evaluating human-in-the-loop AI-assisted methods for data curation, data analysis, and behavioral experiments. These efforts will support decision-making to enhance community resilience against compound risks from extreme weather events

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 To acquire high-quality data from well-controlled field configurations that inform residential building designers and equipment standards organizations about space conditioning and ventilation system performance characteristics, especially the air distribution system(s), when applied in

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
