Technology Transfer is an intensely dynamic field, and the process of moving federal scientific and technological research from the lab to the marketplace teems
To combat COVID-19 amid supply shortages in 2020, health care facilities across the U.S. resorted to disinfecting personal protective equipment (PPE), such as
Researchers at the National Institute of Standards and Technology (NIST) have discovered a potential source of error when using acoustic waves to measure the
This NIST-wide collaborative project aims to improve biotechnology and medical diagnostics by increasing the resolution and precision of measurements of cells
Presently used methods to measure CO2 and other emissions from smoke stacks have errors of 20 % or more depending on the level of swirl in the flow. The
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
The use of microfluidics to make mechanical property measurements is increasingly common. Fabrication of microfluidic devices has enabled various types of flow

We present a new particle tracking algorithm to accurately resolve large deformation and rotational motion fields, which takes advantage of both local and
The dynamic gravimetric standard is used to calibrate micro-flow meters and to conduct research on new flow sensors. This micro-flow standard measures mass
A compressor is used to pressurize up to twenty-five 40 L gas cylinders to 35 MPa. The cylinders can then be used as a source of rapidly changing gas flow by
NIST uses pressure, volume, temperature, and time (PVTt) standards to calibrate gas flow meters. PVTt flow standards generate selected, steady gas flows through
NIST’s wind tunnel can produce air speeds between 0.15 m/s and 40 m/s. The air speed reference is a Laser Doppler Anemometer (LDA) with an uncertainty of 2.5 %
