Abstract

fetched live from OpenAlex

The article explores a novel method of synthesizing silver nanoparticle using aqueous extract of Capsicum chinense Jaqc. The capsaicinoid alkaloids and polyphenols served as an reducing and stabilizing agent in the formation silver nanoparticles. The formation of silver nanoparticle was confirmed by the surface Plasmon resonance which occurred at 430 nm. A gradual colour change of the reaction medium occurred from colourless to pale yellow tinge followed by pale red and then to intense reddish brown colour. The completion of nanoparticle synthesis occurred at 6 hr, as further increased in reaction time showed a marginal rise in the intensity of colour. The characterization of the formed silver nanoparticle was carried out using UV Visible Spectrophotometry and Transmission Electron microscopy. The antibacterial studies were carried out using well diffusion technique using pure culture of Escherichia coli, which showed an inhibition zone of 11.8 mm at a dosage of 70 μg/ml.

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.
