Abstract
The layer-by-layer (LBL) adsorption of polyelectrolytes onto charged surfaces from aqueous solutions produces multilayered surface structures. A multilayer film of polydiallyldimethylammonium chloride (PDDA) and polystyrenesulfonic acid, sodium salt (PSS), prepared using 1.0 M NaCl in the polymer solutions, has a vermiculate morphology with roughness greater than 30 nm. Atomic force microscopy (AFM) investigations show that the morphology of the films can be annealed by the introduction of salt solutions of various concentrations. Roughness measurements taken at various times after immersion in salt solution indicate that the decrease in surface roughness is consistent with second-order kinetics. A model is proposed to explain the morphology annealing that relies on the presence of salt ions that free up polymer−polymer contacts, allowing new ones to form. The formation of new polymer−polymer contacts results in a new film morphology.

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
