Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose...

Structural Metrology of Advanced Manufacturing Processes

Ongoing
Understanding material structures in advanced manufacturing is crucial because it enables precise control over material properties, leading to improved performance, efficiency, and cost-effectiveness in production processes. However, this understanding poses many challenges, such as the...

Terahertz Imaging and Sources

Ongoing
Over the past several years, we have focused on bolometric detection of THz radiation. Our initial work on cryogenic detectors has been extended to antenna-coupled bolometers operating at room temperature. These detectors provide a rugged, low-cost alternative for homeland security applications; e.g...

Theoretical Mass Spectrometry

Ongoing
No Description Intended Impact Unknown compounds will be identified more reliably. Quality control for the NIST Mass Spectrometry Database will be enhanced. Goals Develop software tools for predicting microcanonical branching fractions automatically. This is currently too laborious and too technical...

Theory: Designing the Nanoworld

Ongoing
Developing and exploiting nanodevices for quantum and nanotechnologies requires nanoscale and atomic scale modeling of ultrasmall structures, devices, their operation, and their response to probes. Key challenges of understanding physics at the quantum/classical interface and measurement at the...

Thermoelectric Measurements

Ongoing
Thermoelectric effects enable the inter-conversion of thermal and electrical energy, with applications that include solid-state waste heat recovery in engines for automotive and industrial manufacturing; power generation for aerospace, non-terrestrial exploration, and remote sensing; and...

Time Measurement and Analysis Service (TMAS)

Ongoing
The TMAS meets the requirements of any facility or organization that needs to maintain a high accuracy time standard. TMAS customers include calibration and metrology laboratories, telecommunication providers, instrumentation manufacturers, military installations, defense contractors, government...

TMAS Data Service

Ongoing
A commercial time measurement system can also be used to achieve similar results by building-in a comparable GPS receiver to generate the file format compatible with TMAS service. Commercial manufacturers can sell the equipment with this option, which would be activated when customers subscribe to...

Topological Insulators

Ongoing
Dichalcogenide-Based Topological Insulators A family of TI materials can by synthesized by combining binary compounds of Bismuth (Bi) or Antimony (Sb) with Selenium (Se) and Tellurium (Te) to form Bi 2Se 3, Bi 2Te 3, and Sb 2Te 3 compounds. In these material compounds, the spin of the electron has a...

Transport Property Measurements for Semiconductors and Energy Materials

Ongoing
The image above is an exploded cross section diagram representing the simplified structure layers in a MOSFET transistor. Thermoreflectance (TR) laser-based measurement techniques, a key focus of this project, can measure the thermal properties of substrates, thin films, multilayer structures, and...

Trapped Sr+ ion clock; a secondary realization of the SI second

Ongoing
The single 88Sr + clock is attractive for both its frequency accuracy and for its relative simplicity. The 674 nm clock transition has been independently studied at several NMI’s at the 10 -17 level [1-4]. Advances in light source technology [5,6] may allow operation with just two lasers: one for...

Trapped Ion Optical Clocks

Ongoing
This project uses techniques from quantum information science to enable precision metrology. We use the dipole-forbidden 1S 0 - 3P 0 transition in singly-ionized aluminum as an stable frequency reference (natural linewidth ~8 mHz), which we detect using quantum logic spectroscopy with a second ion...

Ultrafast Spectroscopy to Advance Microelectronics

Ongoing
Continued advancement in microelectronics, including analog and digital electronics, power electronics, optics and photonics, and micromechanics for memory, processing, sensing, and communications as defined by the OSTP “National Strategy on Microelectronics Research,” requires knowledge of material...

Using Quantum Information for Thermodynamics

Ongoing
We re-envision thermodynamics using the mathematical and conceptual toolkit of quantum information theory. We call this research “quantum steampunk,” after the steampunk genre of art, literature, and film that juxtaposes Victorian settings with futuristic technologies. Leveraging quantum...

X-ray Testbed for Breakthrough Catalyst Measurements

Ongoing
Interested in collaborating? See below What does this project do for industry? Current measurement techniques are unable to follow the reaction pathways during catalysis and are limited to observing only the end products or looking at catalysts outside of realistic reaction conditions. Our new...
