Abstract
This research work’s aim was to enhance the biocompatibility of the commercially pure titanium (cpTi-2) surface via Au-ion irradiation. Various ion dosages, i.e. [Formula: see text] (Au-11), [Formula: see text] (Au-12) and [Formula: see text] (Au-13) ions[Formula: see text][Formula: see text][Formula: see text]cm[Formula: see text], were produced by exposing the polished cpTi-2 samples to Au-ion beam at room temperature. The surface topographic features of cpTi-2 and the effects of Au-ion-implanted surfaces were examined by atomic force microscopy and XRD analysis. Open-Circuit Potential (OCP), Potentiodynamic Polarization Scans (PPS) and Electrochemical Impedance Spectroscopy (EIS) were used to compare the electrochemical behavior of the cpTi-2 and Au-ion-implanted samples in Ringer’s lactate (RL) solution at 37 ∘ C. The effects of Au-ion irradiation on the proliferation of mesenchymal stem cells (MSCs) were estimated during 24[Formula: see text]h and 48[Formula: see text]h of exposure. Based on the experimental results, Au-12 samples presented more positive OCP and lower corrosion rate in RL solution than the Au-11 and Au-13 samples. No significant change in the morphology of the MSCs was observed after exposure to the Au-ion-implanted samples. Similar to the controlled medium, the percentage of viability of the cells of the cells on Au-12 increased from 75% to 165% on the surface of Au-13 samples during 48[Formula: see text]h of incubation indicating the positive effects of Au-ion irradiation for biocompatibility.

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 it
