Ferrocenylalkylthiolate labeling of defects in alkylthiol self-assembled monolayers on gold
Bibliographic record
Abstract
Coverage defects in alkylthiol self-assembled monolayers (SAMs) are critically important to function related to electron transfer from soluble redox probes. There is therefore a need for an accurate and direct measurement of the number and type of coverage defect in a range of SAMs. Ferrocenyldodecanethiol (FcC(12)SH) has been assessed as an electrochemically-addressable label of coverage defects. It is shown that short time exposure of a SAM to FcC(12)SH leads to a quantifiable Fc coverage (Gamma(Fc)), with Gamma(Fc) < 1% readily measurable. The voltammetric signature of FcC(12)SH label is also able to differentiate types of defect in a given SAM. A number of SAM preparation conditions are assessed for the density and type of coverage defect. This labeling method therefore will be a useful tool for research into SAM property-function relationships.

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.
