Abstract

fetched live from OpenAlex

Hybrid core-shell polymer-semiconductor or polymer-metal microspheres were used in the "bottom-top" approach to production of nanocomposite materials with periodic structures. In the first step CdS and Ag nanocrystals were synthesized in situ on the surface of polymer microspheres using ion exchange between the counter ions in the electrical double layer of latex beads and ions in the liquid medium. In the second step a low-Tg polymeric shell was synthesized on the surface of hybrid particles, which upon annealing of the periodic array of three-layer microbeads formed a matrix. The proposed strategy employing hybrid microspheres as the functional structural blocks shows a new way to produce optically responsive materials with periodicity commensurable with the wavelength of light, an intrinsic property of photonic crystals.

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.
