Generation and Integration of NaOH into NaCl Clusters in Supercritical Water: A Molecular Dynamics Study on Hydrolysis Product Partitioning
Bibliographic record
Abstract
The interaction of water with NaCl nanoparticles at supercritical conditions has been studied by molecular dynamics (MD) simulation. During the nanoparticle nucleation process, water is not only physically adsorbed to the periphery of the NaCl cluster but also exists in a confined state within subsurface regions for several picoseconds. Electrostatic fields generated by the coalescing ions are shown to be on the order of 10(10) V/m, which can drive the hydrolysis of confined water molecules. A molecular mechanism for the sodium chloride hydrolysis reaction at supercritical conditions is suggested. It involves proton transfer from water to chloride ions, followed by hydrolysis product partitioning. We provide MD results displaying the subsurface hydroxide localization in amorphous NaCl clusters, as well as the partitioning of the HCl into the supercritical water phase.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
