Abstract

fetched live from OpenAlex

The adsorption of insoluble surfactants, spread as a monolayer at the gas-solution interface (GS), onto an electrified metal-solution (MS) interface of a gold single-crystal electrode has been investigated. A Langmuir trough converted into an electrochemical cell was employed in these studies and the adsorption of insoluble surfactants on the Au electrode surface was measured using electrochemical techniques. The results of these experiments have shown that the transfer of insoluble surfactants from GS onto the MS interface is strongly affected by the electrode potential and the transfer ratio is 1:1 only at the potential of zero charge (pzc). UV-Vis and light scattering experiments were employed to demonstrate that insoluble surfactants may be desorbed from the electrode surface at very negative potentials. The desorbed surfactants are trapped in the subsurface region in the form of aggregates, most likely micelles. When the electrode potential is changed to a value close to pzc the micelles spread back onto the electrode surface. The potential induced adsorption of micelles proceeds through a hemimicelle stage. We have shown that the shape and size of the hemimicelle may be conveniently controlled by the electrode potential.

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.
