Highly Parallel, Nanoscale Stripe Morphology in Mixed Phospholipid Monolayers Formed by Langmuir−Blodgett Transfer
Bibliographic record
Abstract
Atomic force microscopy (AFM) has been used to investigate the morphology of mixed monolayers of 1,2-dilauroyl- sn -glycero-3-phosphocholine (DLPC) and 1,2-dipalmitoyl- sn -glycero-3-phosphocholine (DPPC) deposited onto mica by the Langmuir−Blodgett technique. At compositions near the critical point where phase separation is first observed by AFM, this binary lipid mixture yields a regular nanometer-scale pattern of highly parallel stripes. The area fraction covered by the stripes in the AFM images, their height, and mechanical properties are consistent with phase separation into solidlike DPPC stripe domains and a liquidlike DLPC matrix. The orientation of the stripes has been found to always be perpendicular to the film transfer direction, even when the substrate orientation is varied. This indicates that the film deposition process plays an important role in the generation of the stripe pattern. AFM images of films deposited onto mica at different surface pressures and substrate pulling speeds provide physical insight into the process of stripe formation.

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.
