On the interfaces between organic bio-sourced materials and metals for sustainable electronics: the eumelanin case
Bibliographic record
Abstract
Abstract Organic bio-sourced materials featuring charge transfer and transport properties are of high interest in the field of sustainable (green) electronics, which aims at alleviating the environmental impact of conventional electronics. Such materials may contain, after extraction from biological media, traces of salts that can dramatically affect their electrical response, because of electrochemical processes at organic bio-sourced material/metal contact interfaces. Eumelanin, a bio-sourced pigment, is an attractive candidate for sustainable electronics. This work reports on chemical and structural changes occurring at interfaces between metal electrodes (Pd, Cu, Fe, Ni and Au) and hydrated films of eumelanin, under bias. The parameters affecting such changes, i.e. the chloride content in eumelanin, the relative humidity of the environment and the type of eumelanin (synthetic versus natural), were investigated. Our work contributes to establish criteria for selecting metal contacts suitable for the fruitful exploration and exploitation of organic bio-sourced materials in sustainable electronics.

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.
