# The lattice parameter of Nickel, a material of the MatWerk knowledge graph. The quality is measured as a measurement datum; the datum carries the number
# (nfdi:NFDI_0001007, a literal) and points to its unit, which is an individual of measurement unit label, not a literal. The unit label has its own value, the symbol.
# The knowledge graph's materials tab names the material 'Nickel' but the sources used here record no measurement of it, so the number is the textbook value for face-centred cubic nickel at room temperature.
