Abstract
Natural compounds cholic acid and β-cyclodextrin are attached separately as pendant groups in a copolymer with N, N ′-dimethylacrylamides. The formation of supramolecular hydrogels is induced by inclusion complex formation between cholic acid and β-cyclodextrin moieties as evidenced by rheological analysis and 1 H NMR spectroscopy. Storage modulus of the hydrogel shows a maximum value when the molar ratio of cholic acid to β-cyclodextrin units is adjusted to 1:1. The concentration of the hydrogel can be as low as 5.5 wt %. Both shear-thickening and shear-thinning have been observed when the shear rate gradually increases from 0.01 to 100 s –1 . The inclusion complexation renders the gel–sol process reversible under heating and cooling cycles. The self-healing of such hydrogels is observed and confirmed by step-strain rheological measurements. The dynamically reversible host–guest complexation provides reasonably good mechanical properties of the cross-linked polymer network. The natural origin of the constituents may make the hydrogels suitable candidates for biomedical applications pending further tests.

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 it
