Data from NIST TN 2006 'Interlaboratory mechanical-property study for Cobalt-Chromium alloy made by laser powder-bed-fusion additive manufacturing' DOI: 10.6028/NIST.TN.2006. Data from Figures 2, 3, 4, and 6, and Table 4.

Distributes NIST estimate of official U.S. time over the Internet in real time, using Network Time Protocol (NTP) and other time data formats to automatically synchronize clocks in computers and network devices to official U.S. time as realized by NIST several billions of times per day. This official U.S. time is the NIST estimate of Coordinated Universal Time (UTC), and called UTC(NIST).

Sulfonephthalein pH indicator dyes have historically been noted for impurities originating from the synthesis process which lead to batch to batch differences in pH measurements. Uncertainties up to 0.1 pH units have been attributed to impurities in these reagents.

This dataset provides the NIST Software Assurance Metrics And Tool Evaluation (SAMATE) Software Assurance Reference Dataset (SARD) - a set of programs with known security flaws. This will allow end users to evaluate tools and tool developers to test their methods.

The data is for the companion paper: ZH Levine et al., The detection of carbon dioxide leaks using quasi-tomographic laser absorption spectroscopy, Atmospheric Measurement Techniques, in press (to appear 2016). The data include measurements carbon dioxide in the atmosphere in a field in Ft. Wayne, Indiana as well as simulations of such measurements.

Extensible, public domain software for modeling magnetic behavior of ferromagnetic materials at nanometer resolution. Source code, in C++ and Tcl/Tk, is included.

This folder contains image data sets from 14 separate serial sectioning sessions. The entire data folder consists of 1379 8 bit tif images and is 47.3 GB in size. Serial sectioning was performed using FEI Helios 660 NanoLab focused ion beam scanning electron microscope (FIB SEM) and Auto Slice and View G3 software. The sample was a heavy metal stained and resin embedded Caenorhabditis elegans (C. elegans) that were exposed to 60 nm Au nanoparticles. Detailed descriptions of the worm preparation and resin block processing are described in Johnson, M.E. et al. (ACS Nano, 2016).

Software for the solution of elliptic partial differential equations using finite elements with adaptive mesh refinement and multigrid techniques.

SRM 1632e Trace Elements in Coal (Bituminous) - This Standard Reference Material (SRM) is intended primarily for use in the evaluation of techniques used in the analysis of coals and materials of a similar matrix.
