3D shape and size data for 10084 and 14163 lunar regolith particles

Data provided by  National Institute of Standards and Technology

This database contains 3D shape and size data for 10084 (Apollo 11) and 14163 (Apollo 14) real lunar regolith particles, along with STL files for the approximately 14,000 particles studied via X-ray micro-CT and X-ray nano-CT. The database also contains similar information for the lunar regolith simulant JSC-1A but for over 100,000 particles. There are also images for all 10084 and 14163 particles examined by SEM, which are different particles out of the same material.

Current Population Survey: Basic Monthly

Data provided by  United States Census Bureau

To provide estimates of employment, unemployment, and other characteristics of the general labor force, of the population as a whole, and of various subgroups of the population. Monthly labor force data for the country are used by the Bureau of Labor Statistics (BLS) to determine the distribution of funds under the Job Training Partnership Act. These data are collected through combined computer-assisted personal interviewing (CAPI) and computer-assisted telephone interviewing (CATI).

A Synthetic Methodology for Preparing Impregnated and Grafted Amine-Based Silica-Composites for Carbon Capture

Data provided by  National Institute of Standards and Technology

The database includes thermal data analysis for silica-composites that conclude the loading amount of amine adsorbents of each composite as well as each specimen's ability to adsorb CO2. The data repository includes raw data files for: thermogravimetric analysis (TGA) weight loss and CO2 adsorption traces, and Fourier Transform Infrared Spectroscopy (FTIR) spectra?s. For more information see the readme and data documentation. A complete manuscript describing data collection, analysis, and database documentation is to be published. File formats for data include: .txt and .csv.

Sound Pressure Spectral Density at 1 Hertz and 1 Hour Resolution Recorded at SanctSound Site SB01_01

Data provided by  National Oceanic and Atmospheric Administration

This record represents the sound pressure spectral density (PSD) levels derived from raw passive acoustic data. The hourly PSD levels were calculated as the median of mean-square pressure amplitude (µPa^2) with a frequency resolution of 1 Hz from 10 Hz to 24,000 Hz over no less than 1,800 seconds in each hour and converted to decibels (dB re 1 µPa^2/Hz). These data were recorded at SanctSound Site SB01_01 between November 12, 2018 and January 28, 2019.
