NIST ThermoData Engine - Pure Compounds, Binary Mixtures and Reactions - SRD 103b

The ThermoData Engine fully implements all major principles of the concept of dynamic data evaluation formulated at NIST?s Thermodynamics Research Center (TRC). Dynamic data evaluation relies on large electronic databases to store the currently known experimental data along with detailed descriptions of relevant metadata and uncertainties. Combining this data with expert software allows the ThermoData Engine to producing data compilations 'to order' which include all major thermophysical properties (such as density, vapor pressure, heat capacity, enthalpies of phase transitions, critical properties, melting and boiling points, etc). As the name of this resource implies, its scope is pure compounds, binary mixtures and reactions. If you are only interested in pure compounds please see NIST ThermoData Engine - Pure Compounds - SRD 103a (https://www.nist.gov/srd/nist-standard-reference-database-103a).

NIST ThermoPlan - Experimental Planning and Coverage Evaluation Aid for Thermophysical Property Measurements - SRD 167

This web application provides free and open access for the broader research community to the experimental planning utilities that are incorporated into ThermoData Engine (TDE) [J. Chem. Inf. Model. 2005, 45, 816-838]. TDE provides recommendations for the relative merit of a proposed measurement via assessment of the existing body of knowledge, including availability of experimental thermophysical property data, variable ranges studied, associated uncertainties, state of prediction methods, and parameters for deployment of prediction methods. The web applications provides utilities for the assessment of specific property measurements for pure and binary chemical systems, the broader data needs of pure systems, and recommendations for binary mixture measurements that could extend the current UNIFAC model.    The primary focus of this recommendation service is molecular organic compounds. Some common inorganic and organometallic compounds are included, but, in general, polymers, radicals, ions, salt and acid solutions, metals, metal oxides, and inter-metallics are not considered.

QFlow 2.0: Quantum dot data for machine learning

Using a modified Thomas-Fermi approximation, we model a reference semiconductor system comprising a quasi-1D nanowire with a series of five depletion gates whose voltages determine the number of quantum dots (QDs), the charges on each of the QDs, as well as the conductance through the wire. The original dataset, QFlow lite, consists of 1 001 idealized simulated measurements with gate configurations sampling over different realizations of the same type of device. Each sample data is stored as a 100 x 100-pixel map from plunger gate voltages to (i) current through the device at infinitesimal bias, (ii) output of the charge sensor evaluated as the Coulomb potential at the sensor location - the experimentally relevant parameters that can be measured, (iii) information about the number of charges on each dot (with a default value 0 for short circuit and a barrier), and (iv) a label determining the state of the device, distinguishing between a single dot, a double dot, a short circuit, and a barrier state. The expanded dataset, QFlow 2.0, consists of 1599 idealized simulated measurements stored as roughly 250 x 250-pixel maps from plunger gate voltages to (i) output of the charge sensor, (ii) net charge on each dot, and (iii) a label determining the state of the device, distinguishing between a left, central, and right single QD, a double QD, and a barrier or short circuit (no QD) state. In addition, the QFlow 2.0 dataset includes two sets of noisy simulated measurements, one with the noise level varied around 1.5 times the optimized noise level and the other one with the noise level ranging from 0 to 7 times the optimized noise level.

Volume Fraction and Temperature Measurements of 30 cm Acetone, Ethanol, Methanol, Pool Fires

This dataset documents a series of time-averaged gas species measurements made along the centerline of methanol, ethanol, and acetone pool fires steadily burning in a quiescent environment. All gas species measurements are obtained using a Gas Chromatograph/ Mass Spectrometer System (GC/MS). Measurements were made at different heights along the centerline of the fire and repeated at least twice for each location. Gas species volume fractions were determined via the GC/MS using predetermined calibration factors. Soot mass fractions are simultaneously measured during the gas sampling process. The gas species volume and soot mass fractions are compared at different heights within the fire and across a variety of different fuels. Other fire parameters are measured as well, including time-averaged temperature measurements and mass burning rates. The dataset provided here are CSV files listing the volume fractions and temperature measurements made in 30 cm diameter Acetone, Ethanol, and Methanol pool fires.  A technical note (https://doi.org/10.6028/NIST.TN.2082) describes the collection and analysis of these datasets in further detail.

High-Resolution X-ray computed tomography (XCT) image data set of additively manufactured cobalt chrome samples produced with varying laser powder bed fusion processing parameters

This data contains X-ray computed tomography (XCT) reconstructed slices of additively manufactured cobalt chrome samples produced with varying laser powder bed fusion (LPBF) processing parameters (scan speed and hatch spacing). A constant laser power of 195 W and a layer thickness of 20 µm were used. Unoptimized processing parameters created defects in these parts. The as-built CoCr disks were 40 mm in diameter and 10 mm in height, with no post-processing step (e.g. heat treatment or hot isostatic pressing) used. Five mm diameter cylinders were cored out of each disk, and regions of interests (ROIs) within the cylinders were measured with XCT. The voxel size is approximately 2.5 µm, and approximately 1000 x 1000 x 1000 voxel three-dimensional images were obtained, for an actual volume of about  (pi/4) x (2.5 mm)^3 in case of the approximately 2.5 µm voxel data sets. The data set contains two folders ('raw' and 'segmented') with 5 zipped tiff image folders, one for each sample. The images in the 'raw' folder are the original 16-bit XCT reconstructed images. The images in the 'segmented' folder are the segmented images. 'setn' in the file name represents the sample set and 'samplen' represents the sample number.  The final trailing -n represents the number of the image in the stack where higher number is toward the top of the sample.

macOS Security Compliance Project

The macOS security compliance project is an open source effort to provide a programmatic approach to generating security guidance. This project can be used to create customized security baselines of technical security controls by leveraging a library of atomic actions which are mapped to compliance requirements in existing security guides or used to develop customized guidance. Through the use of a library of atomic actions that enhance security, and mapping them back to existing guides and policies, a single project can support multiple security guides and regulated industry policies while also allowing for documentation and QA to be uniformly managed through a single effort. This approach simplifies, and radically accelerates, the updating of annual security guidance through a unification and standardization of effort.Rationale for this project:Normalize and accelerate annual adoption of OS/Hardware by having guidance available to meet the needs of new operating systems on releaseReduce worldwide effort in creating annual guidance by unifying and consolidating compliance efforts into a single projectDevelop a methodology to foster collaboration between baseline authors, reducing overhead and redundancyUnify approach in setting controlsProvide MDM/EMM/security/audit vendors and Apple insight into customer hardening needsImportant note: This project is a programmatic approach to security policy and can produce output content to be used IN CONJUNCTION with management and security tools to achieve compliance.

Ideal-gas Thermochemical Properties for Carbon Dioxide and its Isotopologues Calculated from Partition Functions

Tabulations at 1 K intervals from 1 K to 6000 K of the partition function and standard-state isobaric heat capacity, entropy, and enthalpy for the 12 natural isotopologues of CO2, along with their standard uncertainties. Calculations performed with a partition function constructed from spectroscopic and theoretical data as described in the paper: S.A. Tashkun and A.H. Harvey, "Partition Functions and Ideal-Gas Thermodynamics for Carbon Dioxide," submitted to J. Phys. Chem. Ref. Data (2025). Note that the model does not account for dissociation of the CO2 molecule, making the results incomplete above approximately 3500 K. Text files have numbers for the corresponding isotopologue, where 6, 7, and 8 stand for the oxygen isotopes 16-O, 17-O, and 18-O, and where 2 and 3 stand for the carbon isotopes 12-C and 13-C. Thus, 626 refers to the most abundant isotopologue with two 16-O atoms and one 12-C atom. The file CO2-total.txt has values of the isobaric heat capacity, entropy, and enthalpy, and their standard uncertainties, calculated by averaging the 12 isotopologues according to the natural isotopic abundances as given by IUPAC. These heat capacities were used for the CO2 equation of state presented in the abovementioned paper.

Thermodynamic Data from Unpublished Sources to Support the New Reference Equation of State for Carbon Dioxide

During work on the new reference equation of state for carbon dioxide [E.W. Lemmon, A.H. Harvey, and R. Hellmann, NIST Internal Report, to be published in 2025], we obtained unpublished data from several sources.  These represent numerical values for data only presented graphically in a publication, or in some cases data not present in the publication at all. With the permission of the authors, we document and deposit these data here so they will be available for future workers.  These include data for the melting curve at high pressures, the isochoric heat capacity (including near the critical point and in the two-phase region), the sound speed and density at high pressures, and the vapor pressure of the liquid.  It also includes values of the second, third, and fourth virial coefficients calculated by R. Hellmann from state-of-the-art pair and three-body potentials.For ease of electronic processing, the data elements are formatted as comma-separated values (.csv).More details about the file contents are in the README.txt file and in the headings of individual files.The literature papers connected with these data are as follows:-- E.H.

AM Bench 2022: Cross sectional microstructure of single laser tracks produced using different processing conditions and 2D arrays of laser tracks (pads) on solid plates of nickel alloy 718

The following data files include microstructure measurement results associated with the 2022 Additive Manufacturing Benchmark test series (AM Bench 2022) AMB2022-03 set of benchmarks. These AMB2022-03 benchmarks explore a range of individual and overlapping melt pool behaviors using individual laser tracks and 2D arrays of laser tracks (pads) on solid metal IN718 plates. For the individual laser tracks, a range of laser parameters was used, with variations in laser power, speed, and spot diameter. For the laser pads, the laser scan patterns and most of the laser parameters match those used for the 2.5 mm legs from the AMB2022-01 3D builds. The laser tracks and pads were cross sectioned at different locations and examined using scanning electron microscopy (SEM) electron backscatter diffraction (EBSD) and energy dispersive spectroscopy (EDS). Descriptions and measurement data for all of the other AMB2022-03 measurements may be found on the AM Bench website at www.nist.gov/ambench.The AM Bench measurements metadata catalog provides both a web search interface and API access to extensive linked data associated with these measurements (see Data Access link to explore this related resource).  The SciServer AM Bench collaborative compute platform provides a mechanism for exploring and analyzing the AM Bench datasets directly on a data server without the need to download large datasets (see Data Access link to explore this related resource).
