Electron-Solid Interactions

Ongoing
A measuring instrument produces a signal that depends upon the value of the measurand. The value and its uncertainty are inferred from the signal by using a model of their relationship. Erroneous models lead to erroneous inference. The accuracy of SEM (scanning electron microscopy) is limited by

Embedded Intelligence in Buildings Program

Ongoing
Objective To develop and deploy advances in measurement science that will improve building operations to achieve lower operating costs, energy waste, occupant comfort/safety/security, and smart grid integration through the use of intelligent building systems. What is the problem? Over 80% of the

Embodied AI and Data Generation for Robotics

Ongoing
Objective To facilitate the adoption of AI-based robotic approaches in practical manufacturing scenarios by creating test methods that target AI-enabled robotic systems, evaluating the performance of AI-enabled robotic systems, and creating manufacturing-relevant and AI-centric datasets. Technical

Emerging Hardware for Artificial Intelligence

Ongoing
Here is a brief description of our work with links to recent papers from our investigations, broadly classified as experimental and modeling. A brief overview of Josephson junction-based bio-inspired computing can be found in our review article. Experimental We have facilities to develop our devices

Emerging Technologies in Healthcare

Ongoing
It is hard to imagine a world now without sophisticated medical devices, efficient electronic data transfer of real-time health information and high-tech operating rooms – health IT solutions that are improving outcomes and transforming healthcare delivery. Over the past several decades, NIST has

End-to-End Quality Priority and Pre-emption

Ongoing
The Middle Class Tax Relief and Job Creation Act of 2012 (H.R. 3630) appropriated $7 billion for the establishment of a nationwide interoperable public safety broadband network under FirstNet, an independent authority in the National Telecommunications and Information Administration (NTIA). FirstNet
Energy Monitoring Systems promise to deliver real-time, detailed energy end-use information to building occupants.

Energy Measurements for Existing Residential Buildings Project

Ongoing
Objective: To improve estimates of residential whole-building energy consumption by 2014 through characterization of uncertainties of tools used in providing energy feedback to building occupants and selecting retrofit options to improve the performance of existing buildings. What is the new

Energy Storage & Delivery

Completed
Our program will address key measurement issues related to structure and dynamics of important classes of PEM materials, including emerging systems like block copolymers, polymer blends, and candidate materials proposed by industry leaders like GM. We are developing advanced methods that illuminate
Engineered Designed Lattice Ferroelectric

Engineered Designer Lattices for Quantum Systems

Ongoing
Exposing the low-dimensional materials to a superlattice periodic potential is an effective way to engineer their electronic and other solid-state properties. One example is the moiré superlattice, created by stacking two-dimensional layers at a twist angle, which leads to novel band structures and

Engineered Materials for Resilient Infrastructure Program

Ongoing
Objective - To develop and deploy measurement science to reliably assess the current and future performance of engineered materials in support of resilient infrastructure given exposure to chronic (e.g., materials degradation) and episodic (e.g., earthquakes) hazards. What is the technical idea? To
Map of the world with the engineering biology topics covered in Americas, Europe, and Asia meetings

Engineering Biology Metrics and Technical Standards for the Global Bioeconomy

Ongoing
Stakeholders from the Americas, Asia and Australia, and Europe and Africa, came together through a series of regional workshops in Washington D.C., Singapore, and Brussels, respectively, to identify specific areas for development, both technical and non-technical towards continued scale-up and economic growth across the bioeconomy.

Engineering Living Measurement Systems to Sense PFAS

Ongoing
Per- and polyfluoroalkyl substances, PFAS, are thermodynamically stable organic fluorinated chemicals that are resistant to traditional degradation pathways leading to concern for bioaccumulation. These compounds originate from several industrial manufacturing processes and are found in soil systems

Engineering and Optical Characterization of Magnetic Nanoparticles (MNPs)

Completed
Nanomagnets by Design Nanoparticles are an important subclass of low-dimensional magnetic materials displaying size-dependent magnetic behavior. The controllable magnetocrystalline anisotropy introduced at nanoscale size regimes (as low as 3 nms in diameter) allows for MNPs of ferro/ferrimagnetic

Engineering of G Protein-Coupled Receptors

Ongoing
A trait of all life is the ability to sense and respond to changing environments, and the largest family of eukaryotic proteins that sense and respond to extracellular signals are called G Protein-Coupled Receptors (GPCRs). In humans, over 800 GPCRs detect a wide range of biological and chemical

Enriched Silicon and Devices for Quantum Information

Ongoing
Enriching silicon from 5% to <1 ppm 29Si Groundbreaking work around the world has realized qubits in silicon using metal-oxide-semiconductor (MOS) devices, single atomic dopants/defects and SiGe heterostructures, and, in all cases, the qubit coherence and fidelity properties are improved when using

Environmental Leaching of Nanoparticles from Consumer Products

Ongoing
New nanotechnology-based consumer products are currently entering the market at a rate of 3 or 4 per week, and it is estimated that $2.6 trillion in manufactured goods will contain nanotechnology by 2014. Unfortunately, the overall safety of short- and long-term exposure to nanoparticles and the

Environmental Metrology Measurement Assistant (EMMA)

Ongoing
Quantification of environmental metrology data can be complex at the level on which NIST operates. Projects often include dozens of samples from multiple matrices and can target well over 300 analytes of vastly different chemical properties, each of which must be individually assessed. Quality

Environmental: NIST Radiochemistry Intercomparison Program (NRIP)

Ongoing
The NRIP includes five matrices (acidified water, air filters, soil, synthetic urine and synthetic feces) of test samples spiked with a well-characterized solution that contains alpha-, beta-, and gamma-emitting radionuclides (see Table 1). The NRIP participants decide which radionuclides they will
