Abstract

fetched live from OpenAlex

The phase behavior of A(BC) n BA multiblock copolymer melts is investigated using self-consistent mean-field theory (SCMFT). Solutions of the SCMFT equations corresponding to hierarchical lamellar structures are obtained. The free energy of these structures are used to construct phase diagrams. It is predicted that hierarchical lamellar structures with different number of “internal” BC layers can be formed. The number of BC layers of the stable lamellar structure is determined by the competition between chain entropy and interfacial energy. It is found that more BC layers are preferred when the interactions between A and BC blocks are much stronger than that between B and C blocks.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
