13 Mar 2023, NPL News NPL and the University of Utrecht, Netherlands have collaborated to develop new SI-traceable gas reference materials and a fast calibration approach to improve the quantification and comparability of proton-transfer reaction mass […]
In a brightly lit subterranean lab at the National Institute of Standards and Technology (NIST) sits a room-sized electromechanical machine called the NIST-4 Kibble balance.The instrument can already measure the mass of objects of roughly […]
January 03, 2023 We typically think of the ocean’s color as blue, but in some places, it looks blue-green. That’s because those areas are teeming with single-cell plants called phytoplankton, which contain chlorophyll and reflect […]
by Xiaoke Yan, et al. The influence of impurities on the shape of the freezing curves of the triple point of water (TPW) in three small TPW cells was investigated using the freezing curve analysis […]
An improvement to a Nobel Prize-winning technology called a frequency comb enables it to measure light pulse arrival times with greater sensitivity than was previously possible — potentially improving measurements of distance along with applications […]
The BIPM is pleased to announce the publication of the first key comparison report embedding machine-readable (XML and JSON) versions of the document. Use of the PDF/A-3 standard in this way was originally suggested by […]
The results of the first international comparison of the measurement of graphene have been published in 2D Materials, led by NPL, through the Versailles Project on Advanced Materials and Standards (VAMAS) and in collaboration with […]
The National Institute of Standards and Technology (NIST) invites learners of all ages to explore and discover a wide variety of Science, Technology, Engineering, and Mathematics (STEM) resources using the recently launched Education portal and […]
