Abstract
The significance of the parameters involved in the synthesis of rare-earth metal–organic frameworks (RE-MOFs) has not been studied in depth. Design of experiments (DoE) is used herein to determine the impact of seven synthetic parameters on the yield and surface area of Y-UiO-66 (UiO = University of Oslo). The seven synthetic parameters are evaluated through 16 experiments, leading to a new synthetic procedure for Y-UiO-66 that increases the yield from 30 % to 84 % while maintaining high crystallinity and surface area. These results show that a simple screening design, using DoE, is useful for the improvement of MOF synthesis. The new procedure is successfully adapted to scale-up the reaction twenty times, as well as to improve the yield of Ho- and Yb-UiO-66, demonstrating that it can be extended to lanthanoid analogues of UiO-66. The results obtained from the design were used to improve the yield of Tb-CU-27 (CU = Concordia University) with only one experiment, suggesting that the synthetic parameters identified as being significant for Y-UiO-66 have a similar effect on other RE cluster-based MOFs.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
