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).
