Abstract

fetched live from OpenAlex

Abstract Nanoparticle technology has made an essential contribution to the pharmaceutical industry and has received considerable attention in comparison with the other domains. In the present study, ionic gelation via a novel combined system of nebulizer and falling film (IG‐NFF) has been proposed. The purpose of the design of this system is to increase the contact surface between the chitosan and sodium tripolyphosphate (STPP) for the preparation of monodisperse and spherical chitosan nanoparticles, because in both nebulizer and falling film systems, the surface‐to‐volume ratio of liquid increases. The formation of these nanoparticles is based on ionic interactions between the negatively charged phosphate groups in the STPP and positively charged amine groups on the chitosan. In this research, the effects of chitosan concentration, STPP concentration, the distance of the nebulizer from the inclined plate, gas to liquid flow rate ratio, and the initial chitosan solution pH on the z‐average size, polydispersity index (PDI), and morphology of nanoparticles formed by IG‐NFF were studied. The results showed that the IG‐NFF process has the ability to produce spherical particles with highly uniform sizes. The mean size of obtained chitosan nanoparticles was in the range of 80–320 nm, and the PDI value ranged from 0.08–0.30.

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.
