AM Bench 2022 ASTM E8 Macroscale Tension at Different Strain Rates on As-built IN625
Data provided by National Institute of Standards and Technology
Macro-scale tensile data on additively manufactured (AM) IN625 in the as-built microstructural condition at room temperature and at different strain rates are provided in this data publication. The specimens are machined in accordance with ASTM-E8 subsize specimen with a gauge width of 6 mm and a gauge thickness of 4 mm. Three specimens are tested at a nominal strain rate of 0.001 1/s and 2 specimens are tested at a nominal strain rate of 0.01 1/s on a servo hydraulic material testing machine using a constant crosshead displacement rate of 0.03175 mm/s and 0.3175 mm/s, respectively.

Nanoindentation study on the phase transformation of single crystal silicon of different crystallographic orientations using a spherical indenter probe
Data provided by National Institute of Standards and Technology
The effect of the crystallographic orientation on the primary and secondary phase transformations of single-crystal silicon (Si) during indentation was investigated in a statistical instrumented-indentation study using a spherical diamond probe with a nominal tip radius of 5 µm. The primary phase transformation from the Si-I to Si-II phase were initiated above a threshold pressure during loading and assumed to be reflected as change in slope or a plateau-like discontinuity in the loading curve (pop-in event).

Segmentation of lipid nanoparticles from cryogenic electron microscopy images
Data provided by National Institute of Standards and Technology
Lipid nanoparticles (LNPs) were prepared as described (https://doi.org/10.1038/s42003-021-02441-2) using the lipids DLin-KC2-DMA, DSPC, cholesterol, and PEG-DMG2000 at mol ratios of 50:10:38.5:1.5. Four sample types were prepared: LNPs in the presence and absence of RNA, and with LNPs ejected into pH 4 and pH 7.4 buffer after microfluidic assembly. To prepare samples for imaging, 3 ?L of LNP formulation was applied to holey carbon grids (Quantifoil, R3.5/1, 200 mesh copper).

Computer Forensic Tools and Techniques Catalog
Data provided by National Institute of Standards and Technology
The Tool Catalog provides an easily searchable catalog of forensic tools and techniques. This enables practitioners to find tools and techniques that meet their specific technical needs. It provides the ability to search by technical parameters based on specific digital forensics functions, such as disk imaging or deleted file recovery. Note: All information is provided by the developer. In addition, the Tool Catalog also provides a picture of the digital forensics tool landscape, showing where there are gaps, i.e., functions for which there are no tools or techniques.

Wi-Fi and Bluetooth I/Q Recordings in the 2.4 GHz and 5 GHz Bands with Low-Cost Software Defined Radios
Data provided by National Institute of Standards and Technology
This dataset consists of baseband in-phase/quadrature (I/Q) radio frequency recordings of Wi-Fi and Bluetooth radiated emissions in the 2.4 GHz and 5 GHz unlicensed bands collected with low-cost software defined radios. A NIST technical note describing the data collection methods is pending publication. All I/Q captures are one second in duration, with a sampling rate of 30 mega samples per second (MS/s), and a center frequency of 2437 MHz for the 2.4 GHz band captures and 5825 MHz for the 5 GHz band captures.

NIST Fingerprint Registration and Comparison Tool (NFRaCT)
Data provided by National Institute of Standards and Technology
The NIST Fingerprint Registration and Comparison Tool (NFRaCT) is a cross-platform GUI application which allows a user to load a pair of fingerprint images, find corresponding points in both images, register and crop the images, and finally compute a series of measurements on the registered images as described in NIST Special Publication 500-336
