Abstract

fetched live from OpenAlex

We employed synchrotron infrared spectromicroscopy to provide new insights into the development of self-assembled fibrillar networks. The noncovalent interactions responsible for the occurrence of transient junction zone in 12HSA arise because of hydroxyl−hydroxyl hydrogen bonding. This may result from the preferential arrangement of carboxylic acid groups to dimerize within the fiber, resulting in a reduction of the fiber−solvent interfacial tension. As well, synchrotron infrared spectromicroscopy indicates that the crystallization process of SAFiNs efficiently displaces solvent from the interface of the growing crystals contributing to the epitaxial growth into axially symmetric elongated aggregates. The periodicity in the density of hydrogen bonding resolves the supramolecular chirality of 12HSA fibers.

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.
