Stabilisation of spread monolayers of an amine-functionalised biphenyl mesogen by association with a carboxymethyl cellulose salt
Bibliographic record
Abstract
The monolayer-forming capabilities of a tertiary amine-capped dialkyloxy biphenyl mesogen at the air-water interface were studied. It was found that stable monolayers are obtained in the presence of a water-soluble polymer in the subphase, notably the sodium salt of carboxymethylcellulose. Furthermore, the formation of a surface-adsorbed polymer layer, either by aspiration of the depletion layer or by heating, prior to the spreading of the mesogen resulted in higher surface pressures. The stable monolayers were successfully transferred to glass and aluminium substrates to give multilayer Langmuir-Blodgett films. Reflection Infrared Spectra of the transferred films were obtained, and they indicated that both components are indeed present and that the biphenyl moiety and alkyl spacer of the mesogen both have a net orientation perpendicular to the film surface.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
