Potential Primary Measurement Tool for the Quantification of DNA

Ongoing
The biotechnology industry relies primarily on absorbance and fluorescence methodologies to assess DNA mass. However, these measurements can be seriously compromised by impurities in the DNA preparations or state of the DNA itself. These techniques are also not traceable to the SI because the

Powder Diffraction SRMs

Ongoing
This program strives to produce the highest-quality, traceable powders and other artifacts for x-ray diffraction calibration. (to be completed)

Power Conditioning Systems for Renewables, Storage, and Microgrids

Ongoing
Objective: To establish standards and measurement methods, and test for smart grid and microgrid Power Conditioning Systems needed to transition from today’s low penetration of nondispatchable intermittent renewable energy sources to flexible grid operations that can actively adjust to varying grid

Power Quality Measurements and Fault Detection and Identification

Completed
Traditionally, disturbance detection relies on customer calls to the utility and through the SCADA (Supervisory Control and Data Acquisition) system. A major disadvantage of SCADA is that the measurements are not synchronized, which means that the fault detection process is not precise or timely

Precision Electro-Mechanical Experiments (PREME)

Ongoing
NIST-4 Kibble Balance Previously called ‘the Electronic Kilogram’ Project, a major component of PREME is the realization of SI unit of mass, the kilogram, using the NIST-4 Kibble balance, the fourth generation of Kibble balances at NIST. This is accomplished through a high-accuracy comparison of

Precision Materials for Quantum Devices

Ongoing
MBE System Our fabrication system is composed of ultra-high vacuum (UHV) chambers that support the in-vacuum exchange of 75 mm wafers without exposure to air as seen in Figure 1. These chambers are: (1) a deposition chamber with electron gun deposition, UHV compatible sputter guns, in situ shadow

Precision Measurement Grants Program

Ongoing
If funding is available, two new grants in the amount of $50,000 per year will be awarded for the initial period of October 1 through September 30 of the following year. Each award may be continued for up to two additional years; however, future or continued funding will be at the discretion of NIST

Precision metrology with integrated photonics

Ongoing
This project develops integrated photonics– devices based on waveguides that are fabricated in a nanoscale device layer on a silicon wafer –for the purposes of exploring nonlinear science, enabling new applications with scalable integrated photonics light sources, and enhancing classical and quantum

Precision Spectroscopy and Quantum Control of Trapped Molecular Ions

Ongoing
Spectroscopy and Quantum Control of Molecular Ions Molecules exhibit vibration and rotation of their nuclei, degrees of freedom not present in atoms, and less stringent selection rules for transitions. This creates experimental challenges and great opportunities for exploring new physics. In this

Precision Timing for Smart Grid Systems

Completed
Objective: The key objective is to support the power sector industry through research and development in the metrology for online and predictive precision timing characterization necessary for grid monitoring and control applications. This project strives to support to the Smart Grid Testbed and the

Precision X-ray Emission Line Measurements

Ongoing
Precise knowledge of the shape and position of x-ray emission lines is the basis of connecting x-ray diffraction measurements to the Système Internationale d'Unités (SI), the official worldwide standard for making any measurement. Measurements of position of x-ray emission lines have been made been

Precursor Material Qualification

Completed
To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological, size

Prediction of Global Warming Potential

Ongoing
Goals Use ANN models to fit RF and .OH rate constant data k(.OH). Be able to predict RF, k(.OH), and GWP with reasonable accuracy using readily available information. Create a screening tool based on the ANNs.  Research Activities Improve the performance of rate constant prediction. Compare rate

Presidential Management Fellows Program

Ongoing
Key Aspects of the PMF Program: The PMF Program is currently administered by the PMF program Office within OPM. OPM announces the opportunity to apply for the PMF Program (usually in the late summer or early fall). Applicants go through rigorous assessment process to determine Finalists. Agencies

Pressure

Ongoing
Piston Gauge (29010C - 29040S) This service provides calibrated secondary standard piston gauges, calibrated electronic pressure instruments, and special tests of customer supplied piston gauges. Measurements of pressure are available for submitted calibration items for the range from 10 kPa to 280

Primary optical watt radiometer (POWR)

Ongoing
The POWR, including the detector module, was completely designed by NIST to have the versatility to grow with NIST's needs and embrace new technologies. It provides optical power measurements with uncertainties of 0.01 % ( k=1), which have been verified by an intercomparison with two other cryogenic

Probing Graphene Electronic Devices with Atomic Scale Measurements

Ongoing
Two of the remarkable features of graphene that are opening avenues to multiple applications are its high transport carrier mobility and the broad tunability of its electronic properties. Graphene charge carriers can be tuned continuously from negative carriers (i.e., electrons), to positive (holes)
