Abstract

fetched live from OpenAlex

Abstract ZnO nanoparticles (NPs) were prepared and characterized by different analytical methods and then they were used to decorate with N , N ´-bis(salicylidene)ethylenediamine (salen) in order to perform as receptor for the metal ions in an aqueous medium. The results show that ZnO-salen selectively detects Al 3+ ions in aqueous medium since the intensity of fluorescence has been enhanced significantly. However, the presence of K + in the medium further intensified the fluorescence emission for the [ZnO-salen-Al 3+ ] system. The above system has been applied to recognize Al 3+ and K + in cells by developing the cell images, for which, the fluorescence image is brightened if a human glioblastoma U251 cell contains [ZnO-salen-Al 3+ ] + K + ions, consisting of the fluorescence titration. The binding global constant for Al 3+ and the subsequent recognition of K + by ZnO-salen resulted in β 2 (Al 3+ ) = 6.61 × 10 3 and β 2 (K + ) = 3.71 × 10 3 with a detection limit of 36.51 µM for Al 3+ and 17.39 µM for K + . In the cell toxicity analysis, the cell viability was over 85% for the ZnO-salen even in the concentration as high as 100 mM.

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.
