Observations of CO2, CH4, and CO mole fractions from the NIST Northeast Corridor urban testbed

Data provided by  National Institute of Standards and Technology

WARNING (updated: May 5 2023): This dataset has been updated and is now found at https://doi.org/10.18434/mds2-3012. We have become aware of errors in the inlet heights at multiple sites and have corrected these in the newest version. Hourly observations of CO2 and CH4 from tower-based sites in the NIST Northeast Corridor network; CO observations from one site. Data files are comma delimited (CSV). Measurements of each species may be from two or more different heights above ground.

The NMR Spectral Measurement Database: A System for Organizing and Accessing NMR Spectra of Protein Therapeutics

Data provided by  National Institute of Standards and Technology

The Nuclear Magnetic Resonance Spectral Measurement Database (NMR-SMDB) was developed for the purpose of organizing and searching NMR spectral data of protein therapeutics, linking spectra to corresponding sample information and enabling quick access to full datasets and entire studies. In addition to supporting internal NIST research, the system could facilitate data access to stakeholders outside of NIST, and future versions of the database software itself could be installed by others for their own data storage and retrieval.

Dilute solution properties and force field model parameters of LLDPE in good solvent from "Structure-dilute property relationships of comb-like macromolecules in a good solvent" and "The importance of branch placement on the dilute solution properties of comb-like macromolecules".

Data provided by  National Institute of Standards and Technology

These data and the coarse-grain force-field parameters were used to produce publication (1) "Structure-dilute property relationships of comb-like macromolecules in a good solvent" by Robert J. S. Ivancic (OrcID: https://orcid.org/0000-0001-9969-2534, National Institute of Standards and Technology, Material Measurement Laboratory, Division 642, Group 1), Sara V.

MAM Consortium Interlaboratory Study Raw Data

Data provided by  National Institute of Standards and Technology

These LC-MS and LC-MS/MS raw data were collected for purposes of an interlaboratory study evaluating the multi-attribute method (MAM). Tryptic digests of native NISTmAb (the "Reference" and the "Unknown" samples), degraded NISTmAb (the "pH Stress" sample) and NISTmAb spiked with 15 heavy-labeled synthetic peptides (the "Spike" sample) were sent to each participating laboratory. One injection of each digest was acquired in MS-only mode, while a second injection was acquired in MS/MS mode.

Python scripts used to generate the figures in "An algorithm to identify vapor-liquid-liquid equilibria of binary mixtures from vapor-liquid equilibria"

Data provided by  National Institute of Standards and Technology

The files in this repository can be used to generate the complete set of figures in the paper "An algorithm to identify vapor-liquid-liquid equilibria from vapor-liquid equilibria". The zip file, when expanded, includes a conda environment to populate the dependencies, and a set of python scripts. Running make_figures.py will regenerate all the figures, demonstrating how to use the algorithm.

Datasets from an interlaboratory comparison to characterize a multi-modal polydisperse sub-micrometer bead dispersion

Data provided by  National Institute of Standards and Technology

These four data files contain datasets from an interlaboratory comparison that characterized a polydisperse five-population bead dispersion in water. A more detailed version of this description is available in the ReadMe file (PdP-ILC_datasets_ReadMe_v1.txt), which also includes definitions of abbreviations used in the data files. Paired samples were evaluated, so the datasets are organized as pairs associated with a randomly assigned laboratory number.
