Dataset for: A technique for in-situ displacement and strain measurement with laboratory-scale X-ray Computed Tomography

Data provided by  National Institute of Standards and Technology

This record provides raw and post-processed data used in the associated paper "A technique for in-situ displacement and strain measurement with laboratory-scale X-ray Computed Tomography." The codes used are provided in a separate software publication "SerialTrackXR", also referenced. The data consist of 3D X-ray computed tomography (X-ray CT) scans, projection images, and load/displacement data of two additively manufactured tensile test coupons made from IN718 with different processing conditions.

Python tools for OpenFOAM simulations of fused filaments in embedded 3D printing, Version 1.2.0

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. Using OpenFOAM, we simulated the extrusion of filaments and droplets into a moving bath, for single filaments, single filaments being disturbed by a nozzle, and printing pairs of filaments. OpenFOAM is an open source computational fluid dynamics solver.

OpenFOAM simulations of filament fusion 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. However, moving the nozzle near an existing structure and writing new filaments can cause deformation and lack-of-fusion defects. Using OpenFOAM, we simulated what happens when a nozzle moves near an existing filament, and when a nozzle writes a second filament next to an existing filament. OpenFOAM is an open source computational fluid dynamics solver. This work used OpenFOAM 8 on a computing cluster. OpenFOAM input files were generated using Python 3.7.

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.

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.
