https://w3id.org/delphi/resource/assessment/bragg1915-07--gemini http://purl.org/dc/terms/description Bragg's 1915 conjecture can be tested component by component against COD, AMCSD, and Materials Project: the inter-network spacing increase from ~2.06 A in diamond to ~3.35 A in graphite (close to Bragg's 3.42 A) is confirmed, whereas the conjecture that graphite preserves diamond's puckered two-layer carbon network in a wurtzite-like polytype is refuted (graphite sheets are strictly planar sp2 monolayers with 1.42 A C-C bonds, while the true wurtzite-type hexagonal polymorph of diamond is lonsdaleite). https://w3id.org/delphi/resource/assessment/bragg1915-07--gemini http://purl.org/dc/terms/subject https://w3id.org/delphi/resource/concept/dataset-resolvability-0.2.0

https://w3id.org/delphi/resource/assessment/bragg1915-07--gemini http://www.w3.org/2000/01/rdf-schema#comment Proposed test with existing data: Compare the refined crystal structures of graphite (P6_3/mmc) and diamond (Fd-3m) in terms of (1) inter-sheet spacing (c/2 in graphite vs d_111 in diamond), (2) bulk densities, and (3) whether graphite's carbon layers are puckered tetrahedral bilayers analogous to wurtzite/sphalerite (as in lonsdaleite) or strictly flat planar sp2 honeycomb monolayers. https://w3id.org/delphi/resource/assessment/bragg1915-07--gemini
