The NIST Office of Weights and Measures (OWM) is pleased to announce the schedule for the 2025 Info Hours series. An Info Hour is a one-hour session that
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized time keeping, the
Weights and measures authorities in each U.S. state and local jurisdiction are responsible for the testing and official inspection of electric vehicle (EV) chargers, specifically the measurement devices that deliver electricity as fuel within commercial EV chargers. These devices are commonly
We have a number of opportunities to collaborate with us. See below for details. What does this project aim to do for the chemical industry? Many industrial processes depend on the intermolecular environment- the solvents and ions that surround a molecule. These interactions impact separations
The increasingly complex device requirements for next-generation computing architectures such as neuromorphic computing or nanoelectronic machine learning accelerators present challenges for researchers across the spectrum of institutions, from small businesses and universities to government
Quantum Dot – Surface Acoustic Wave Microwave-to-Optical Transducers In this project, we focus on coupling nanoscale acoustic resonators with InAs quantum dot (QD) single photon sources (Fig. 1). At ultra-low temperatures, such as those in a dilution refrigerator, the acoustic resonators act as

DC voltage references are typically based on calibrated Zener Diodes which are subject to drift and therefore require periodic recalibration against a Primary

We demonstrate a glass microwave microfluidic device for determining the permittivity of a wide range of liquid chemicals from 100 MHz to 10 GHz with relatively
We present on a novel gain extrapolation antenna range, the Compact Homodyne Extrapolation System (CHEXS), that can achieve absolute antenna gain measurements
In this paper we describe an enhanced three-antenna gain extrapolation technique that allows one to determine antenna gain with significantly fewer data points
Description High-throughput (combinatorial) metrologies have evolved as a useful approach to rapidly determine the composition-structure-property relationships
Description The Seebeck coefficient is a widely measured transport property that provides fundamental information on charge carrier transport and the electronic
The Applied Physics Division utilizes a fully automated, dual-chamber molecular beam epitaxy (MBE) system for the growth of advanced, compound semiconductor
