Abstract

fetched live from OpenAlex

Copper nanocrystals have been grown on thin polypyrrole films obtained by electropolymerization on a gold electrode from CuSO 4 solution electrochemically in both potentiostatic (constant potential) and galvanostatic (constant current) modes. A variety of copper nanostructures including fractals, nanowires, and cubic nanocrystals have been observed in the galvanostatic mode, in contrast to a single predominant type of nanostructures obtained by manipulating the under-peak potential (fractals) or over-peak potential (cubic nanocrystals) in the potentiostatic mode. The homogeneous distribution of nanocrystals observed at over-peak potential is consistent with an instantaneous growth mechanism. Depth profiling by X-ray photoelectron spectroscopy further reveals the presence of an ultrathin copper oxide layer on the surface of these nanocrystals.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame distilled prediction

Teacher imitation

Not 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.
