IMPLICATIONS OF THE SYNTHESIS AND STRUCTURE OF THE Sr ANALOGUE OF CURITE
Bibliographic record
Abstract
The structure of the synthetic analogue of curite, Sr 2.82(H2O)2[(UO2)4O3.82(OH)3.18]2, Z = 2, orthorhombic, space group Pnam, a 12.3143(7), b 12.9609(8), c 8.4053(5) A, V 1341.5(2) A 3 , has been refined to an agreement index ( R) of 5.30% for 1369 unique observed (|Fo| ≥ 4sF) reflections measured using monochromatic MoKa X-radiation and a CCD-based detector. The crystal was synthesized from a mixture of uranyl nitrate and SrCl 2 reacted at 185°C for 5 days. The structure determination has demonstrated that the title compound is isostructural with the Pb uranyl oxide hydrate curite. On this basis, a complex series of Sr uranyl oxide hydrates with various Sr:U ratios, analogous to the Pb uranyl oxide hydrate minerals, may exist.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
