Acoustic Techniques in Fluid Metrology

Ongoing
The Fluid Metrology Group leads the world in designing and using gas-filled acoustic resonators for measuring the thermodynamic temperature T, the Boltzmann

Acoustic Thermometry

Completed
By measuring the speed of sound in argon gas, we have determined thermodynamic temperature with unprecedented accuracy in the range 0 °C to 552 °C. Our results

Crystallographic Databases

Ongoing
Components and devices used in a broad spectrum of technology sectors such as health care, communications, energy and electronics are manufactured from

Fixed Point Development : Non-Metals

Ongoing
We are developing new fixed points and new maintenance systems for use with Standard Platinum Resistance Thermometers (SPRTs) below the triple point of water

Gas properties for flow metering

Ongoing
Flow meters that rely on measuring the pressure drop across a laminar flow element can be accurately calibrated using a benign surrogate gas (such as helium or

Inorganic Phase Equilibrium Data

Ongoing
Compile and evaluate phase equilibrium data for NIST Standard Reference Database 31 (Phase Equilibria Diagrams); disseminate the data in a readily accessible

Nanoscale Thermal Properties

Completed
Our goal is to develop measurement techniques to characterize the changes in thermal transport and thermal transition temperatures in polymeric and hybrid

Photonic Dosimetry

Ongoing
As part of the NIST on a Chip program, the Photonic Dosimetry project is developing in-situ sub-micrometer ionizing-radiation dosimetry and calorimetry leading

Photonic Thermometry

Ongoing
Photonic Thermometry is a cutting-edge research program at NIST that aims to break the fundamental limitations of electrical resistance-based thermometry and

Refrigerants and Working Fluids

Ongoing
The conversion of primary energy (e.g. heat generated by the combustion of a fuel) into useful work most often involves a working fluid operating in a

Reliable Vaccine Storage

Ongoing
We study provider-level vaccine storage and temperature monitoring methods to develop best practice guidance for public health audiences.

Renewable Energy and Fuels

Ongoing
Energy is one of the most critical problems facing the United States, with technical, economic, and public policy aspects. Our group develops state-of-the-art

Solvation Free Energies

Ongoing
Measuring and maintaining water quality is increasingly becoming a significant global issue. As new chemicals are introduced into the water supply, development
