Study of conductance through wires grown dielectrophoretically from colloidal gold suspensions
Bibliographic record
Abstract
Gold nanoparticles have been synthesized by the reduction of tetrachloroauric acid in the presence of stabilized capping agents (citrate, polyvinylpyrrolidone, octadecanethiol) and dispersed in either a polar (water) or a non-polar solvent (dodecane).The size distribution of the nanoparticles was determined to be between 10-15 nm from transmission electron microscope images and through a comparison between Mie extinction theory and the measured extinction.Subsequently the particles were aligned into a wire between two gold electrodes through the action of a non-uniform electric field (dielectrophoresis).Conductance measurements through the dielectrophoretic wires showed non-linear conductance steps at integer multiples of Goan indication of a lowdimensional metallic conductor.Wires grown from PVP and ODT capped gold nanoparticles showed conductancs steps at I, 2 G¡ ll.

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.
