The Los Angeles Megacity Carbon Project

Ongoing
Observation Network Tower and rooftop-based in-situ measurements of carbon dioxide (CO 2) and methane (CH 4) are the backbone of the LA Megacity test bed. This surface-based component of the LA observing system includes a network of Greenhouse Gas (GHG) monitoring stations that is intended to

Low Temperature Regenerator and Pulse Tube Losses

Ongoing
All-digital radio communication between the various forces of the U.S. military is required to improve communications to the level needed in the near future. Such communication requires analog-to-digital converters of speeds only possible with low temperature superconducting electronics. The

Low-Complexity Optimized MIMO Receiver

Completed
Transmit diversity is a very significant characteristic which a Multiple-Input Multiple-Output (MIMO) communication system possesses. Nevertheless, due to the size of a mobile phone, the 10λ distance between two antennas allowing each channel to be independent is difficult to fulfill. Against this

A Low-Cost Robot Science Kit for Education

Ongoing
Despite its low cost, Legolas has been demonstrated for machine learning-driven hypothesis design, discovery, and validation. For the last four years, Legolas has been used in hands-on courses at the University of Maryland to teach next-generation workforce skills, including ML, control systems

Low-Cost Sensor Platform

Ongoing
This platform uses commercially available sensors and microcontrollers, making them a fraction of the cost of traditional GHG measurement systems. Though these sensors are less accurate than traditional measurement systems, NIST hopes to reduce sensor uncertainty to the 1 ppm level with frequent

AI for Low-Field MRI

Ongoing
The overall goal of this project is to use an AI network to overcome the low Signal-to-Noise-Ratio (SNR) of low-field MRI, so that we can produce quantitative ADC measurements. This will be accomplished by a collaborative effort imaging with a low-field Hyperfine instrument, with the physicists

Low-GWP Refrigerants for High-Efficiency HVAC&R Equipment

Completed
Objective - To develop heat transfer and system performance information that will assist in the selection and implementation of the best replacements for high-GWP hydrofluorocarbon (HFC). What is the new technical idea? Most of the currently used HFC refrigerants will be phased out or phased down

Low-Phase Noise Frequency Synthesis

Ongoing
Frequency synthesis plays an essential role in virtually all present-day commercial, industrial, and military technologies. State-of-the-art low-noise frequency synthesis is a crucial technical asset to high-resolution imaging and radar, high-speed telecommunications, and efficient management of the

Lunar Spectral Irradiance (LUSI)

Ongoing
Earth observing satellite sensors were once the exclusive domain of large satellite platforms used by government agencies for the purpose of national security, defense, weather prediction and disaster mitigation. These satellites typically carry onboard radiometric calibrators that along with pre

Machine Learning Driven Self-correcting Autonomous Metrology Systems (SAMS)

Ongoing
While NIST-on-a-Chip has produced quantum and nanophotonic measurement solutions that can significantly reduce calibration frequency, their transition from laboratory to marketplace depends on seamless integration into user workflows. Our research addresses a fundamental challenge: maintaining

Machine Learning Fluid Equations of State

Ongoing
Understanding the thermodynamic properties of fluids and fluid mixtures is of central importance in many fields of science and engineering ranging from medicine to consumer products. The nature of the particles in a fluid can vary greatly depending on the type of interactions present, e.g., dipole

Machine Learning for Internet of Things (IoT)

Ongoing
Resource Allocation in IIoT Systems As with any large an complex system, Industrial Internet of Things (IIoT) deployments require the system operator to efficiently allocate the available bandwidth, computing, and energy resources. This is challenging because IIoT systems, especially large ones, can

Machine Learning for Materials Research: Bootcamps and Workshops

Ongoing
The 2016 bootcamp consisted of three days of lectures covering data processing, supervised learning and unsupervised learning as well as hands-on exercises using MATLAB covering a range of data analysis topics touching on each of the lecture . Example topics include: Identifying important

Machine Learning to Predict Food Provenance

Ongoing
Adulteration of food and food products is a pernicious problem which is difficult to solve as supply chains and international trade routes become increasingly complex; yet agriculture contributed over $1 trillion to the US GDP in 2017, [1] illustrating the importance of protecting this and related

Machine Learning to Predict Multicomponent Colloidal Crystals

Ongoing
There is a direct link between a material’s macroscopic properties and its microscopic structure, which makes rational bottom-up self-assembly a powerful tool for engineering properties of materials. In general, colloids are facile material building blocks whose shape, charge, and surface

AM Machine and Process Control Methods for Additive Manufacturing

Completed
Objective Develop algorithms, methods and standard protocols for Additive Manufacturing (AM) process control, and implement it with software and hardware tools for open control of AM systems to enable more flexible process optimization by manufacturers. What is the Technical Idea? Additively

Machine Translation

Ongoing
Current MT technology evaluation activities: OpenMT: A biannual NIST evaluation of text-to-text MT technology. Focus is placed on the core task of MT technology where information learned is applicable to other MT technology types. Past MT evaluation activities: LORELEI/LOREHLT, 2016-2019: Low

Macromolecular Architectures

Ongoing
This project’s purpose is to synthesize and characterize model thermoplastics, thermoplastic elastomers (TPE), and mixed resins with systematic variation of polymer sequence, chemistry, and architectures to generate libraries of quantitative structure-property relationships validated by multiple

Macromolecule and Nanoparticle Composition and Architecture

Completed
Bringing new products to market requires measurements for rapid, quantitative assessment of composition and structure. To this end, NIST has developed a series of mass spectrometry-based tools that decrease the time necessary to achieve measurement success while producing more accurate results. The

MAGIK Offspecular Reflectometer

Ongoing
Polarized-beam measurements are possible with the use of a 3He analyzer. This instrument is an evolution of the AND/R reflectometer, which was located on the NG-1 guide. MAGIK is located along the NG-D guide in the expanded guide hall (part of the NCNR's Expansion Initiative).

Magnetic Imaging

Completed
Advanced magnetic devices and storage media will rely on ultra thin ferromagnetic films; since such films are quasi two-dimensional magnets, they can have strong perpendicular magnetic anisotropy (PMA). Optimization of future materials, including improved yields, requires an ability to measure film

Magnetic Materials Metrology

Ongoing
Our aim is to develop the metrology for control and manipulation of magnetic anisotropy in magnetic materials. This includes development of the measurement science for quantification of the magnetic properties (e.g., magnetic anisotropy, magnetic exchange) and the structure-property-processing
