Abstract

fetched live from OpenAlex

This study investigates the effect of nanoparticles, namely silver nitrate (AgNO3) and barium titanate (BaTiO3), on polyvinyl alcohol (PVA)/ polyethylene oxide (PEO) blends prepared by casting at different weight ratios.Improving the structural and optical properties of polymer blends by incorporating nanoparticles is an important strategy for obtaining materials with advanced functions.X-ray diffraction (XRD) results confirm the semicrystalline nature of the pure polymer blend, the best peak was obtained at 2 = 19.58,with high-intensity other peaks at 2 = 22.1 and 23.69, which increased in crystallinity after the addition of nanoparticles due to the formation of distinct new crystalline phases at 2 =19.61, 22.4, 23.59, 19.4, 23.46, 23.51, 31.92,39.25, 47.74, 50.94, 56.48, 65.71, 54.61, 31.65,39.03, 45.15, 56.29, and 65.96.Fourier transform infrared (FTIR) spectroscopy revealed distinct peaks at: 2884 cm -1 (C-H and C-O vibration in PEO/PVA), a broad band at 3300 to 3500 cm - (O-H groups, more in PVA), 1340.73 cm - (N-O vibration of AgNO3), and 606.30cm - (Ti-O bond of BaTiO3).UV measurement results show that Pure PVA/PEO polymers blend absorb in the UV region 190 to 250 nm, and the addition of nanoparticles increases the absorption intensity between 300 and 600 nm.

Full frame distilled prediction

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.
