A Neutron Reflectivity Study of Poly(<i>N</i>-isopropylacrylamide) at the Air−Water Interface with and without Sodium Dodecyl Sulfate
Bibliographic record
Abstract
The properties of poly( N -isopropylacrylamide) (polyNIPAM) at the air/water interface, with and without sodium dodecyl sulfate (SDS), were measured by neutron reflectivity and surface tension. Below the lower critical solution temperature (LCST), polyNIPAM adsorbs at the air/water interface to give a thin (δ ∼ 1.5 nm) layer with a low water content approximately equal to phase-separated polyNIPAM above the LCST. Above the LCST the adsorbed polymer layer increases by a factor of 10 approximately equal to the effective diameter of a single phase-separated polymer chain (a globule). Polymer-bound SDS lowers the density of adsorbed polyNIPAM because of electrostatic effects.

How this classification was reachedexpand
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.
