Abstract

fetched live from OpenAlex

Enzyme entrapment in hydro-ionic liquid gels (HydrIL gels) was explored as an enzyme immobilization strategy. The liquid phase of the gels was a mixture of buffer and tributyl methyl phosphonium alkanesulfonate [P4441][RSO3] ionic liquids. The ionic liquid modifies the liquid phase creating a more “organic” hydrophobic microenvironment around the enzyme. In the esterification of a secondary alcohol by Candida antarctica Lipase B, a 20-fold enhancement in final substrate conversion was achieved using an HydrIL gel compared to a standard poly(acrylamide) hydrogel. Co-polymerization of the poly(acrylamide) matrix with acrylate monomers led to further increases in reaction rate. A CalB HydrIL gel was reused over 10 reaction cycles, achieving a consistent performance from the fifth cycle. IL leaching became undetectable from the third reaction cycle.

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.
