Abstract

fetched live from OpenAlex

The enthalpies of solution (Δ sol H ) of carbon dioxide (CO 2 ) in two aqueous solutions ( w = 0.1500 and w = 0.3000) of monoethanolamine (MEA) have been measured at two temperatures (322.5 K and 372.9 K) and pressures up to 5 MPa. Measurements were carried out by a flow calorimetric technique using a custom-made flow-mixing unit combined with a SETARAM C-80 isothermal differential heat-flux calorimeter. Enthalpies of solution of CO 2 (Δ sol H ) have been obtained as function of loading α (moles CO 2 /mol amine). Solubility data of the gas into the different absorbent ( s ) were derived from the enthalpic data.

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.
