Abstract

fetched live from OpenAlex

We study thermodynamic behaviors of 1-propanol (abbreviated as 1P) in ternary 1P−salt−H 2 O in order to elucidate the effects of salt on the molecular organization of H 2 O. We determine the excess partial molar enthalpy of 1P, H 1P E, as a function of the mole fraction of 1P, x 1P, and the salt. We examine the x 1P dependence of H 1P E, and changes induced by the presence of salt are used to elucidate the effect of the salt on the molecular organization of H 2 O. We previously found that an NaCl ion pair binds 7 to 8 molecules of H 2 O, but has no effect on H 2 O outside of the hydration shell. Na 2 SO 4 and NaClO 4, on the other hand, modify the molecular organization of H 2 O each in different ways. In particular, ClO 4 - seems to participate in the hydrogen bond network of H 2 O and to retard the degree of fluctuation inherent in liquid H 2 O.

Full frame distilled prediction

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.
