The National Institute of Standards and Technology (NIST) is currently using Johnson noise thermometry (JNT) to determine the deviations of the International...
Resistance thermometers using wires of rhodium with 0.5 mol % of iron (Rh-Fe thermometers or RIRTs) were first made by H Tinsley & Co in 1969 for applications...

We report the Residual Resistance Ratio (RRR) and resistance ratio W(GaMP) (gallium melting point) values for well-annealed samples of the original SRM 1967...
Technology life cycles are becoming shorter as is the time for those technologies to become ubiquitous in the society. The Industrial Revolution took about 150...
The normal self-heating coefficient for standard capsule-type resistance thermometers is gas-mediated over most of their designed range of use. This is readily...

To efficiently assemble manufacturing supply chains, manufacturers need to provide precise and easily accessible their manufacturing service capability (MSC)...
We have recently updated the uncertainty budgets for calibrations in the NIST Thermocouple Calibration Laboratory. The purpose for the updates has been to 1)...

We discuss optical two-way time and frequency transfer over air to connect remote optical clocks/oscillators. This method can link remote sites with a residual...
The daily variation (diurnal) in the two-way satellite time and frequency transfer (TWSTFT) difference is one of the most significant instabilities of the...
We evaluate a method for testing the radius of spheres with a hologram that consists of a pair of nested Fresnel zone lenses. The hologram is positioned in the...

With an increasing utilization of nanoparticles (NPs) in consumer products, the potential for release to the environment also increases. It is therefore...
As distributed energy resources are added to existing building systems, and variable priced electricity tariffs are introduced, facility owners may profit from...

As a part of NISTs program to standardize measurements of greenhouse gas emissions, we are developing long-wavelength acoustic flowmeter (LWAF) for accurate...
We discuss a high-speed quantum key distribution (QKD) system with the protocol infrastructure implemented on a single printed circuited board that can operate...
There are now a series of published works related to Differential Fault Attack (DFA) on the Grain family, but most of them require quite a large number...
The objective of this work is to identify compositional changes that could improve the thermal stability of RP-2. For this study, we tested the effect of alkane...
