Abstract

fetched live from OpenAlex

Abstract Ultraviolet (UV) irradiation is an environmentally friendly technique to modify starch. In this study, potato starch films were irradiated by UV (wavelength ∼302 nm) in the presence of sodium benzoate as a photo‐sensitizer (PHS). PHS concentrations in the starch films were varied in the range of 0.2–1.0% (based on dry starch). Cross‐linking reaction was initiated by UV irradiation and proven by gel mass and swelling degree measurement when immersed in DMSO. The modified starch film was characterized by attenuated total reflectance‐Fourier transform infrared spectroscopy (ATR‐FTIR) to investigate the changes of the surface properties with UV irradiation over time. Water contact angle and Tq of starch film were measured to understand the influence of the UV modification. The result showed that water contact angle and Tq of the cross‐linked starch film increased with the dosage of UV irradiation.

Not 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.
