Self-Assembly of Bile Acid–PEG Conjugates in Aqueous Solutions
Bibliographic record
Abstract
Thermoresponsive characteristics of oligo(ethylene glycol) derivatives of lithocholic acid (LCA) depend on the hydrophilic/hydrophobic balance of the compounds. Below a threshold temperature (∼30 °C), one of the derivatives, LCA(EG(4))(2), self-assembles in water into hollow nanotubes that form thixotropic gels at high concentrations. Two concentration regimes were observed in the plateau moduli (G(0) ∼ G'). At high concentrations, the mobility of the nanotubes is restricted at the ordered microdomains acting as cross-links. In semidilute aqueous solutions, the linkers between the aggregated domains in the fragile gel rupture easily, and this effect depends strongly on dilution. Organic hydrophobic additives perturb the self-assembling process, leading to changes in the two transition temperatures and poorer mechanical properties of the gel.

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.
