Code and Results for the Application of Polar SAFT models to Refrigerants
Data provided by National Institute of Standards and Technology
This dataset includes the python scripts and output results for fitting SAFT models to the phase equilibrium density, pressure, and speed of sound for refrigerants. A conda environment file is included specifying the dependencies, and the driver script does all the fitting. The process is carried out in parallel through the use of process-level parallelism. The output files are in the JSON format, in a hierarchical folder data structure. Summary files are generated in the csv format. A README file is included within the zip file.

Digital image analysis tools for pairs of filaments in embedded 3D printing
Data provided by National Institute of Standards and Technology
In embedded 3D printing, a nozzle is embedded into a support bath and extrudes filaments or droplets into the bath. This repository includes Python code for analyzing and managing images and videos of the printing process during extrusion of single filaments, pairs of filaments, and triplets of filaments. The link to the GitHub release goes to the state of the code when the paper was submitted. From there, you can also access the current state of the code.

In situ methane mole fraction observations from three sites in the Washington DC region from the NIST Northeast Corridor Project: January 2015 - December 2022
Data provided by National Institute of Standards and Technology
Methane (CH4) mole fraction data collected from three tower sites in the Washington DC area: Bucktown, MD (BUC, ghg01), Stafford, VA (SFD, ghg65), and Thurmont, MD (TMD, ghg61), as part of NIST's Northeast Corridor Urban Testbed project, presented as 1-minute averages. This data is published for research academic and related non-commercial purposes consistent with NIST?s mandate to further the science and the promulgation of appropriate standards.

Videos of single, double, and triple filaments in embedded 3D printing
Data provided by National Institute of Standards and Technology
These images, videos, and tables show experimental data, where single lines, pairs of lines, and trios of lines of viscoelastic silicone inks were extruded into moving viscoelastic support baths. Lines were printed at varying angles relative to the camera, such that videos and images captured the side of horizontal lines, cross-sections of horizontal lines, and the side of vertical lines. For single lines and pairs of lines, the filaments were also disturbed after printing by running the nozzle next to the construct.

Templates for the Implementation of Rapid GC-MS for Seized Drug and Ignitable Liquid Analyses
Data provided by National Institute of Standards and Technology
This dataset contains templates to assist with the implementation and validation of rapid gas chromatography-mass spectrometry (GC-MS) technology for the analyses of seized drugs (probe tip injection) and ignitable liquids (liquid and solid phase microextraction (SPME) injection). The validation package includes plans and workbooks for each application, both of which can be modified to fit the methods and approaches currently utilized in the laboratory. A standard operating procedure (SOP) for the rapid GC-MS system is also included in the validation package.
