Preparation of the Pure Poly(ϵ-caprolactone)-Urea Complex by Electrospray
Bibliographic record
Abstract
In this work, we demonstrate that electrospray is a simple and efficient method for preparing pure supramolecular complexes between a polymer and a small molecule. Such complexes are often difficult to prepare by conventional methods because of the kinetically favored crystallization of the small molecules. However, the fast solvent evaporation involved in electrospray can circumvent small molecule crystallization. Pure samples of the poly(ϵ-caprolactone)-urea complex were successfully prepared for the first time using the electrospray technique. Infrared spectroscopy, X-ray diffraction and differential scanning calorimetry were used to confirm the purity of the electrosprayed complex and to determine the phase diagram for this system. The electrospray method is similar in concept to the electrospinning approach that we have recently demonstrated, but it proves to be complementary for some challenging samples such as the poly(ϵ-caprolactone)-urea complex.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
