Norway Spruce X-ray Scattering Data Across Nine Moisture Conditions

Small and wide-angle X-ray scattering (SAXS/WAXS) intensities measured for Norway spruce wood under nine distinct moisture conditions, from wet to various relative humidities. The data was collected by researchers from Aalto University using a Xenocs Xeuss 3.0 C SAXS/WAXS device and is associated with a 2022 publication in Nano Letters. Processed files include background-subtracted detector images, azimuthally regrouped data, and merged anisotropic intensity profiles.

Use Cases

• Modeling nanoscale swelling mechanisms in wood microfibril bundles based on anisotropic scattering intensity data.
• Analyzing the impact of relative humidity on wood structure using scattering vector (q) and intensity columns.
• Developing computer vision models to interpret 2D scattering patterns from the provided PNG image files.
• Validating data processing pipelines for SAXS/WAXS experiments using the provided background-subtracted and azimuthally regrouped text files.

Strengths

• Data covers nine precisely controlled moisture conditions, including wet state and relative humidities from 10% to 95%.
• Provides multiple processed data versions per condition, including raw images, azimuthally regrouped data, and merged anisotropic intensities.
• Detailed experimental metadata is provided, including sample-to-detector distances, beam centers, and detector specifications.

Limitations

• Row count and total file size are unknown, which may limit suitability assessment for large-scale ML tasks.
• Column-level documentation is absent; field semantics for the provided text files must be inferred from the description.
• Last update date is unknown; freshness unverified.
