Understanding the thermo-sensitivity of crystalline colloidal arrays formed by poly(styrene-co-N-isopropylacrylamide) core–shell microspheres
Bibliographic record
Abstract
Poly(styrene-co-N-isopropylacrylamide) core–shell microspheres have been synthesized by a two-step surfactant-free emulsion polymerization process. These microspheres are thermo-responsive with a clear volume phase transition around 30 °C and form crystalline colloidal arrays over a wide range of concentrations. The resulting crystalline arrays also display a response to temperature, visible through a change in the diffraction spectrum. However, the response appears to be highly dependent on the microsphere concentration. This behavior originates from a change in the short-range interactions between particles rather than from the volume change of the particles caused by the volume phase transition. Attractive van der Waals interactions increase while repulsions decrease; these changes only affect the equilibrium of concentrated samples, where the interparticle distance is sufficiently short to have an effect.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
