A Visualizing Method for Study of Micron Bubble Attachment onto a Solid Surface under Varying Physicochemical Conditions
Bibliographic record
Abstract
The impinging jet technique, a direct microscopic observation method, is presented to fundamentally study micron bubble attachment onto a solid surface (collector) under well-controlled stagnation flow conditions. The bubble−collector attachment near the stagnation point of an impinging jet is analogous to bubble−fine solid interaction, which is of interest to flotation processes. In this work, bubble attachment experiments were conducted for sodium chloride solutions with various concentrations (10 -1 −10 -4 M) and pH values (2.5−9.0) under a fixed flow intensity (in terms of Reynolds number Re = 200). In addition, the effect of metal ion valence on the bubble attachment was examined as well. Results have showed that the bubble attachment flux was dependent on both solution concentration (ionic strength) and pH, suggesting a strong impact of the electrostatic double layer interaction. In the presence of multivalent metal ions, the bubble attachment rate was noticeably enhanced.

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.
