Abstract

fetched live from OpenAlex

International simple glass (ISG) is a six‐component alumino‐borosilicate glass developed as a reference benchmark glass for six nations collaborating study on high‐level nuclear waste glass dissolution/corrosion mechanism. In this study, aqueous dissolution tests were performed for the ISG using microchannel flow‐through (MCFT) method to evaluate the initial dissolution rate of glass matrix, r 0 , precisely and systematically as a function of solution pH and temperature. The test results indicated that the r 0 shows a “V‐shaped” pH dependence with a bottom at around pH 4 at each temperature. Compared with Japanese reference glass of P0798, for which the r 0 showed a “U‐shaped” pH dependence with a bottom at around pH6 in our previous study, the ISG shows the higher dissolution rate at basic pH, and lower dissolution rate at neutral to acidic pH . The results also indicated that the r 0 increases with temperature according to an Arrhenius law, and the apparent activation energy evaluated from Arrhenius relation is 62–77 [kJ/mol] at any pH from 3 to 10, which suggests the initial dissolution of ISG proceeds controlled by a surface‐reaction mechanism in this pH range.

Teacher imitation

Not 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.
