Abstract
A new method has been developed to study the role of hydrogen bonding in ice adhesion and to minimize the effect of this mechanism on ice adhesion. Metals were coated with a mono-molecular layer that had either strong hydrophobic properties or strong hydrophilic properties. Self-assembling monolayers (SAMs) of varying degrees of hydrophobicity/hydrophilicity were created by mixing the hydrophobic and hydrophilic components. The SAM structure and quality were examined using atomic force microscopy, and the degree of the SAM hydrophobicity/hydrophilicity was characterized by the contact angle of water on the monolayer surfaces. Then, water was frozen on the top of the SAM and the shear strength of the interface between ice and SAM was measured. A good correlation between the contact angle of water and the ice adhesion strength was shown and the fraction of ice adhesion caused by hydrogen bonding was determined. It is revealed that hydrogen bonding significantly enhances ice adhesion. PACS No.: 61

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 it
