NIST Programs to Advance Accurate, Internationally-Recognized Stack Emissions Measurements

September 15, 2016
Author(s)
Aaron Johnson, Iosif Isaakovich Shinder, Rodney A. Bryant, JohnPaul R. Abbott, Keith A. Gillis, Joey Boyd, James Filla, Michael R. Moldover
Accurate flow measurements are essential to quantify the amount of greenhouse gases (GHGs) and other pollutants emitted from power plant stacks. Although protocols have been developed, the uncertainty of stack flow measurements has not been documented.

The National Institute of Standards and Technology (NIST) Standard Reference Materials 2373 is a set of genomic DNA samples prepared from five breast cancer cell lines with certified values for the ratio of the HER2 gene copy number to the copy numbers of

Marie Curies Last Radium Standard Grand Challenge

September 1, 2016
Author(s)
Bert M. Coursey
The last of the radium-226 standards that Marie Curie personally handled is destined for a radioactive materials waste dump. Presented here is a history of the standards and a challenge to the scientific community to present a rationale for why this

Amanda J. Moors, Rebecca S. Pugh, Jody R. Evans, Jennifer M. Ness, Debra L. Ellisor, Melannie J. Bachman
The NIST Reference Materials Production (RMP) Facility at the Hollings Marine Laboratory produces fresh, frozen powder materials which are used as Standard Reference Materials (SRMs) and Control Materials (CMs) from frozen biological, environmental

Extensive sequencing of seven human genomes to characterize benchmark reference materials

June 7, 2016
Author(s)
Justin M. Zook, Jennifer H. McDaniel, David N. Catoe, Lindsay Harris, Marc L. Salit
The Genome in a Bottle Consortium hosted by the National Institute of Standards and Technology, (NIST), is creating reference materials and data for human genome sequencing, as well as methods for genome comparison and benchmarking. Here, we describe a
