This maturity indicator falls under the FAIR principle R1.3: (meta)data meet domain-relevant community standards

The ID of this MI is composed of the following segments (separated by hyphen):

1. Acronym for "Maturity Indicator"
2. The FAIR principle this maturity indicator belongs to
3. The first 10 characters truncated from the SHA-256 hash of the primary reference DOI of this maturity indicator.
4. A short name to distinguish the maturity indicator definition file

This MI is to indicate if "Size Distribution" of the nanomaterial(s) is reported by the nano toxicity study data or not.

This maturity indicator is extracted from the following paper Title: Guidance to improve the scientific value of zeta potential measurements in nanoEHS DOI: https://doi.org/10.1039/C6EN00136J

R1.3

If the size distribution is reported by the nano toxicity study data or not.

The appropriate model for calculating the zeta-potential depends on particle size (through κa) and potentially on shape for the smallest particles. The presence of a macromolecular coating on the particle, or a shell, or any charged (small molecule) ligands can affect the electrophoretic mobility and hence zeta-potential.

If the value is measured and reported in the data, the following field(s) should appear in JSON-LD metadata:

The size distribution should be provided in a machine-readable format (JSON-LD) which can be queried using open universal protocol like HTTP.

The presence of the field "size distribution" in the JSON-LD metadata means the measurement is reported which is the valid result.

For nano toxicity related datasets.
